Many videographers and companies are now delivering

live streaming of events, sports, weddings, plays, graduation

ceremonies, training sessions, news reporting, and promotions.

With free or very affordable CDNs like YouTube Live, UStream,

Twitch LiveStream, Wowza, or any RTMP server you can

easily deliver your live content to any number of people, all

over the world. All you need is a camera, an encoder and an

internet connection.

But what about when you don’t have a good internet

connection? Maybe you are in the middle of a ball field or shooting

at an outdoor gazebo behind the chapel or you find yourself in

the bleachers of a high school football field for graduation? What

if you get to the recital hall or auditorium only to find that there

isn’t wired internet and/or the Wi-Fi coverage is sketchy at best?

Maybe you arrive at the church only to find that someone changed

the IP address for the server or the settings on the firewall?

Teradek VidiU Pro:The Must-Have Tool for

Professional Live Streaming

http://www.streamingmedia.com


WHAT DO YOU DO?As the saying goes, the show must go on. The Teradek VidiU

Pro is the essential tool that solves all these problems and

makes sure that you can deliver your live stream as promised,

regardless of the internet connectivity issues the location may

hit you with. With Teradek’s latest ShareLink™ technology

and VidiU Pro, you guarantee the bandwidth needed to

stream your HD content from anywhere, to everywhere.

ShareLink lets you use up to 4 iPhones and other internet

connections to deliver the combined bandwidth you need

for Live HD streaming, even with poor cell service.

HOW DOES IT WORK?The ShareLink allows you to achieve maximum

bandwidth and ultimate reliability by bonding multiple

internet connections, from different sources, into a single

connection. Bonding is a technology that broadcasters have

been using for years to upload and deliver their content. They

use expensive gear costing many times more than the VidiU

Pro. Teradek products like the Bond II and Cube use cellular

bonding in broadcast environments, so these guys know how

to do it right. With the robust connectivity of ShareLink™,

you can be sure that your HD live video feed will get to your

audience every time.

Let’s use as an example that you are on a ball field with no

internet connection. With a single iPhone you can deliver low-

quality video streams. By bonding a second iPhone you can double

your bandwidth. Utilize up to 4 iPhones together and you can

create a big fat streaming pipe able to handle 720p HD streams.

TECH NOTE 1: Videoguys recommends 720p as the optimal streaming

resolution for all workflows. For internet-based content delivery you

always want to choose progressive over interlaced. While you may have a

pipe capable of supporting 1080p, we’ve seen that only a fraction of your

audience will have the bandwidth to watch 1080p. By going with 720p

you give your audience a great quality HD stream, one that you can be

confident will be delivered to their computer or mobile device.

TECH NOTE 2: Cellular bonding works best when the iPhones are on

different cell carriers (ie Verizon, AT&T, Sprint, T-Mobile) so they are not

competing for the same cell service and bandwidth

When you have your VidiU Pro with you, along with a couple

of iPhones and ShareLink enabled, you always have a backup,

even if the site has internet connectivity. As mentioned in the

tech tip above, if at all possible, try to get your crew to be on


several different carriers so that you can use their iPhones to

maximum benefit.

ShareLink can also be set up to combine wired, Wi-Fi and

USB modem cellular internet connectivity for redundancy.

You can use ShareLink to mix iPhones together with Wi-Fi

and/or wired internet to provide even higher throughput and

redundancy should any of the bonded connections fail or slow

down. That means that if one of the iPhones or connections

fail, the others still work together to deliver the best quality

stream they can. This happens seamlessly and automatically.

ShareLink is available as a subscription plan starting at

just $19.90 per month, accessed through the VidiU App or

ShareLink.Teradek.com.

VidiU Pro does not require cell service to work. It connects to

the internet via wired internet, Wi-Fi or via cellphone(s) using

the ShareLink application. While VidiU Pro is a stand-alone

camera mounted encoder, it can be used with any switcher/

mixer to enable live streaming to your productions. Just plug

the HDMI output of the switcher into the VidiU Pro and start

streaming. So even if you are doing multi-camera shoots, VidiU

Pro is still a very valuable tool to have. We have many customers

using the HDMI output of their Roland, DataVideo, or other

live switcher/ mixer to feed directly into a Teradek VidiU Pro

encoder. This allows you to add live streaming to an existing

live production.

VidiU Pro also allows you to record your streaming output

directly to an SD card for archiving, additional post production

or easy distribution via ftp or services like Dropbox.

WHO SHOULD PURCHASE VIDIU PRO?All of the VidiU family of video encoders for streaming works

great. But if you are doing this professionally, or you are planning

on streaming a once in a life time event then you know you

simply cannot tolerate any hiccups or issues with your stream. If

your internet goes down, you are out of business. There is no way

to make that up. So anyone who produces live video productions

will benefit from the ShareLink function and professional feature

set of the VidiU Pro, and will quickly understand the value of

the added investment for the VidiU Pro. For less than $1,000

and a couple of iPhones that you already have access to, you can

have a bulletproof streaming solution. When you don’t have to

worry about the stream, you can concentrate on getting the best

possible shots, camera angles and content for your production.

New York, New York—Pulling off a live

stream for a complex event in the heart

of Times Square is no easy task, but

five-time Emmy Award winning video

journalist and reporter Michael Artsis

was up for the challenge.

To mark the launch of their new

SideKick installment for the TWIN

Wash laundry pair, LG Electronics

wanted to create a Broadway-inspired

event in the middle of New York’s

Theater District. This event would

consist of six separate performances

throughout the day featuring a

14-foot version of the TWIN Wash

laundry pair, six dancers, and two

16-foot puppets, each operated by

six puppeteers.

Working as a producer with the

nontraditional live experiential media

company Digital Media Etc., Artsis and

his BeTerrific!! team was responsible

for perfectly executing all of the

project’s technical elements. This

included setting up wireless cameras

on the ground and streaming the event

seamlessly to an iconic Times Square

screen hundreds of feet in the air as well

as to multiple live streaming platforms.

“You couldn’t have had cables because

it was on the street in the middle of

Times Square,” said Artsis. “There was

no staging or anything, so regular people

LG Turns to Teradek for “Larger than life” Times Square Product LaunchA complete wireless workflow combining IP and RF expertise.


walking through the area—even the

performers—could have tripped if there

were wires and the feed could have been

disrupted. Realistically, there was no

way to conveniently cable this.”

In addition to the people crawling

everywhere, the sheer amount of RF

and wireless interference in Times

Square could potentially interrupt any

stream or transmission. With this in

mind, Artsis chose to set up a wireless

workflow using Teradek products—

the Bolt, Bond II, Core, and Cube—to

ensure a successful production.

To start, Artsis used the Teradek Bolt

600s for all three cameras to transmit

the feed to their respective receivers,

which were outfitted with directional

panel antennas. The zero-delay video

signals from the Bolts then routed to

the switcher where the final mix was

produced.

After, that final mix was output via

SDI connection into the Teradek Bond II.



Despite not being able to use Ethernet

or satellite connectivity, due to client

demands, Artsis found a way to create

a reliable Internet connection with

Bond through cellular connectivity.

This way, if one network unexpectedly

disconnected, the feed would remain

uninterrupted.

Once the feed was encoded and sent

over IP networks with Bond II, the signal

was directed to Teradek Core. With Core,

Artsis had the freedom to route, DVR,

and configure all of his destinations,

including YouTube Live, Livestream, and

a Teradek Cube decoder that ultimately

fed to the large LG screen for the entire

downtown to see.

“We only do things on a high end,

so we need the best products because

failure isn’t an option,” said Artsis.

“It’s unbelievable how much flexibility

Teradek products give you, and the ease

of setup is completely unmatched. You

couldn’t have given this a more stressful,

challenging environment and, when it

came down to it, everything just worked.”

“It was probably one of the scariest

projects we have ever done,” said Paul

Whitney, F“Due to the ambient waves

that are through the air in Times Square

it was definitely an uphill battle, but

we did not have one single issue. We

depended on Teradek at a high level, and

they came through.”

With this workflow in place—and

some extra support from Dynamic

Digital Displays (D3) and partner Meric

Adriansen—Artsis and Digital Media

Etc. continually aired LG’s theatrical

event successfully during the day. In

the end, the multi-destination stream

reached 400,000 to 500,000 viewers,

giving LG extensive exposure across

different platforms.

“It takes years to build up a

reputation, but only seconds to tear it

down,” said Artsis. “I mean, with my

company BeTerrific!! we’ve established

our viewership throughout the years

by broadcasting high-end events like

Comic-Con and CES. Like those, this

LG production was big enough to

potentially damage that foundation,

but we chose Teradek, who is the

leader in wireless video transmission

technology. Thanks to their products,

we really made the impossible possible.

We couldn’t have done this without

Teradek and their support.”

A revolution is taking place right in our living rooms and spilling into any space

where our Wi-Fi and mobile networks reach. Today’s viewers are watching less

traditional broadcast TV, instead turning their attention to other screens such as

tablets, phones, and computers for their entertainment.

At the same time, advances in technology have allowed almost anyone to become

a “broadcaster.” Anyone with a computer and an internet connection can create live

streamed content and generate audiences in the thousands of people or more.

Live Streaming From (Over The)

Top to Bottom



Additionally, live event producers

are realizing they can multiply their

audiences significantly by providing

a live stream of their events to remote

audiences. Also, there are many

forms of education, entertainment,

and community content that can

find an audience through streaming

technology in a way that just wasn’t

practical with traditional delivery

mechanisms.

The options for how and where you

can produce and deliver live video

content continue to expand. Content

owners and event producers that don’t

consider live streaming can miss

opportunities for audience growth,

revenue, and market share.

WHAT IS LIVE STREAMING?Live streaming is a term that is used

to describe many video applications

and situations, and it can all be a bit

confusing. Here at Telestream, streaming

is in our DNA, so we thought we’d share

what the video streaming ecosystem

looks like from our perspective, what’s

involved, and how you might get started.

There are many types of situations

where live streaming makes sense.

Whether you are a student in high

school or a team of professionals putting

on the evening news, the fundamentals

of live streaming are the same: You need

to capture your content, produce your

show, and encode and deliver (i.e. “live

stream”) that content to a place your

audience can view it.

Let’s take a look at some of the

situations where live streaming

technology is used, things to consider,

and pitfalls to avoid.

1. LIVE EVENTSToday’s fans are increasingly turning

to the web for entertainment—from

music and sports to live interviews,

comedy, and more.

Here are a few examples of events that

can be, and are, streamed live:

Live Sports/eSports/NewsWhen was the last time you watched

recorded sports or news? Sports and

news are two of the main categories of

live events, because of their timeliness.

EducationTeachers and online trainers use live

streaming to make lectures, tutorials,

and other school events available to

anyone connected to the Internet. Many

educators use live streaming as a teaching

tool in a video production course, creating

student-run live shows, or assigning

students to live stream assemblies.

Houses of WorshipReaching home-bound members is

important to many houses of worship

that use live streaming to broadcast

weekly services, as well as special

events such as baptisms, weddings,

confirmations and more.


Meetings/conferencesMany conferences offer

remote access to attendees

who cannot physically travel

to conference locations.

Additionally, many companies

are beginning to take advantage

of technology to live stream

important corporate meetings

to keep all employees informed.

GamingThe growth of Twitch.tv’s

live game streaming site is a

perfect example of how the

concept of traditional television

as entertainment has changed.

Gamers have burst onto the

live streaming scene, and are

gaining enormous audiences, using

live streaming technology to broadcast

themselves playing video games.

These are just a few of the many

examples of live event streaming. The

spectrum of requirements ranges

from premium, multi-day events like

the Olympic Games where temporary

venues are combined with permanent

facilities around the globe, to single-

camera events impressively produced

by a crew of one. Equally there is a

spectrum of solutions to provide live

streaming, encoding, and delivery.

These can be integrated into traditional

outside broadcast trucks, as well as

complete software-based camera

switching, graphics, encoding, and

delivery systems that can be run on

commodity PC workstation hardware.

• Things to consider

º Are you going to repurpose an

event from the venue or are you

going to produce and live stream

the event yourself?°

º Do you need production and live

switching capabilities built in to

your system?

º If you operate a theater/arena/

stadium could you repurpose

feeds from a resident or outside

broadcast system to provide in-

house multiscreen services?

º Is it possible to deliver coverage of

more events by adopting multiple

live streaming approaches?

º Consider the implications of

originating your live service at the

event site, in a central location,

or the capability for both/either

depending on your needs.

• Pitfalls to avoid

º Balancing capabilities and cost

will help determine how much

production should be done on-site

as opposed to a central location.

º Wide area network capabilities

and costs can vary greatly. It

may be relatively inexpensive

to obtain a fast and reliable

connection on a university

campus vs. a remote location.

2. SECOND SCREEN LIVE STREAMING

Traditional television content is

no longer just broadcast on a linear

service. Broadcasters are increasingly

looking to stream their existing content

to multiscreen devices (“over the top”

or OTT).

In this scenario the intention is to

broaden the audience of an existing

channel transmission to allow some or all

of the live programming material to be

viewed via web and mobile devices like

phones and tablets. Since there is pre-

existing infrastructure for creating the

channel content, the ideal live streaming

solution may be a system that can take

input that would normally be used as

final output for the broadcast chain.



Catch-up TV is an internet

television service that repurposes

linear service content to enable video

on demand (VOD) viewing of recently

aired programs. The service is often

funded by advertising, which can

expand advertising opportunities and

increase ad revenue.


º Which is the best output of the

broadcast chain to use for your

service? Is it IP- or SDI-based?

º Will you carry ads from the linear

broadcast feed?


º Do you need to plan for a future

transition from SDI- to IP-based

signal distribution?

º Do you anticipate graphics

or branding requirements

that are unique to multiscreen

delivery? If so, you might need

to provide for a clean feed and

access to graphics metadata

and assets.

º Live content can be preserved for

long-term viewing access. Plan

for potential ad replacement,

audience measurement and

lifecycle management.

º Avoid legacy packaging and

distribution formats for

new services (e.g. Flash and

Silverlight).

º Don’t forget captioning. There

are few mandates for captioning

of streaming video services,

however in the United States,

captions are mandatory for

streaming of content that

was originally broadcast

with captions.

3. MSO FOR CABLE TV PROVIDERS

Increasingly cable, satellite, and

IPTV service operators make their

programming available on their primary

platform, and also stream it live to mobile,

tablet and web platforms to attract

customers to their premium services.

Similar to Scenario 2, Second Screen

Live Streaming, the infrastructure to

produce and deliver content already

exists for cable operators. There is a

complete live channel—just many

more of them. These channels may

have disparate rules depending on the

content itself, the viewer’s location,

and regional implications regarding

blackouts (e.g. sports programs). The

challenges in this scenario are largely

in system scale, management, and

disparate rights management scenarios

that may apply across content channel,

or even a program-by-program basis.



º What targeted devices/players

do you plan to support?

Common packaging and

rights management for targets

are helpful.

º Will you implement your own

streaming origin services and/or

content distribution network?


º Avoid duplicated encoding,

packaging and storage, which

can increase complexity and

drive up costs and resources.

º Rights management

requirements may vary

with content providers and

requirements to support

solutions for regional blackouts.

º Consider future needs for

emerging technologies

(eg. HDR and UHD) even

if you don’t plan to deploy

them initially.

IN CONCLUSIONWhether you’re a crew of one

with a laptop; a production team

in a studio; or a content owner

that needs robust, redundant and

scalable distribution infrastructure,

Telestream’s live streaming provides

purpose-built solutions.

As Tom Griffiths, director of

broadcast and distribution technology

for ITV said at the recent Streaming

Forum in London, “To scale successfully

you can’t take disparate systems for

VOD and for broadcast,” Griffiths said.

“They need to be brought together

into a unified chain in order to deliver

efficiencies, scale, and flexibility.”

(go2sm.com/itv)

So, before you settle on your

solutions, consider the scenarios above.

Also consider that everything live

streamed now has potential to become a

VOD asset for later viewing. It is rare that

a new live streaming service is created

where there is not a legacy library of

content. Sometimes that legacy content

can be used to create a deeper service.

It is also possible that excerpts from

an existing library may be posted to

generate additional marketing demand

for new live content. Of course it is also

typical that live encodings continue

to build this library. It is important

to consider how to make the existing

library accessible, how to operate

a system with a mixture of live and

existing content as well how to preserve

live encodings to grow a resilient library.

While you may have the best content, the quality of the way you share it really is

the most important aspect to online video streaming. You make a huge investment in

producing a live event where audiences will be logging on to see something for the first

and in some cases only time. You can’t ever risk losing those viewers. All live-streamed

events are therefore mission-critical transmissions. And the transport and encoding

engine you use determines the success of your stream.

The internet is at best unpredictable, and the networks you use for the first mile of

your transition can be just as erratic. The good news is that there have been important

advancements such as IP-based bonding and advanced transport technologies that go

beyond basic video encoding to provide broadcast-quality video signals and reliable

bandwidth. There are also different transport protocols that help to reduce artifacts,

jitter, and buffering when viewing live experiences online.

Trusting Your Live Content on

the Internet?What you need to know for successful,

high-quality, online streaming



DEALING WITH THE CHALLENGES

So, you are challenged on all sides, you

need to engage with your audience with

dynamic live content that is delivered

flawlessly online and to every viewing

device. You have to get your camera in

the middle of the action, but to do that

you need to cut the cord so you can shoot

from anywhere, leaving you at the mercy

of the available bandwidth. You have to

produce engaging content consistently,

even while your camera is mobile. Your

job is to produce great content, but you

are spending more time trying to navigate

the technology used to deliver it to make

sure people can actually watch it!

Everything really starts with the

audience and its viewing experience.

Broadcasters have the benefit of being

able to control this experience with

high-quality content and super-reliable

delivery to televisions everywhere. But

what happens when you want to bring

that same experience to online streaming?

How do you ensure the same high-quality

content and reliable delivery?

An added challenge to reliable

delivery is that as our lives become even

more mobile, an increasing amount of

live video content needs to be captured

on the fly—and out in the world. Be it

from a drone, from a body-worn camera,

on the move, in the air—exciting video

can happen anywhere and often in

locations where it isn’t easy to have a

fixed network with reliable bandwidth

ready for your use.

RELIABLE TRANSPORT AND INTEGRATED ENCODING

Transport and encoding are two

separate issues, but both impact

how the audience experiences your

content. Transport deals with how

bytes get from one place to another;

encoding deals with how sounds and

images are converted to bytes and

back. When cutting the cord to capture

content over wireless, you can’t rely

on just one connection. Whether

using cellular or Wi-Fi, issues with

congestion or interruption can ruin

your stream. Bonding multiple signals

allows for consistency in bandwidth

even when one source becomes

unstable. To ensure high quality,

the encoder needs to be part of this


process. When the transmission engine

informs the encoder, the encoder can

adapt dynamically when bandwidth

inevitably increases and decreases—

so losses can be compensated and a

high quality viewer experience can be

automatically maintained.

Streaming directly to an online video

platform (OVP) or content delivery

network (CDN) introduces further

considerations versus streaming to

a studio, where the video is made

available as a baseband signal.

In order to ensure that your content

comes out the other end in as high

quality as it went in, and with as little

delay as possible, you need to solve the

first-mile problem of getting your video

into the cloud over IP-based technologies

and mitigate the issues that make the

internet such a challenging environment

for video streaming. Using advanced

integrated encoding technology allows

you to match the output bitrate of the

encoder to the available bandwidth

dynamically, while you are live

streaming, and automatically, without

any interaction needed from you.

For high-quality online streaming,

you need reliable transport over the

most unreliable of networks, including

cellular networks where the transmitter

is moving at high speed. You need all

this and one other element that many

of the transport level solutions on the

market today leave out: tight integration

with the encoder.

INTEGRATED RELIABLE TRANSPORT PROTOCOL – LRT™

LiveU has been at the forefront of

IP-based live video services for over 10

years. As such, LiveU has seen these

inherent issues for the online streaming

community and developed a Reliable

Transport protocol. LiveU Reliable

Transport (LRT™) brings together the

best of all these techniques into one

integrated protocol that works with

the encoder so you don’t have to do

anything. How?

Packet OrderingLRT uses

numbered packets

so that the packets

can be re-ordered

when they arrive

out of order. This is

a common practice since data often

arrives in a different order than it was

sent, but is an absolute requirement

with connection bonding, where data

usually arrives in a different order

than intended.

Dynamic Forward Error Correction

Another

technique used

in LRT is Forward

Error Correction

(FEC), which adds

some overhead to the stream, with

the idea that the small amount of

additional overhead can be used to

recover lost data faster than resending a

packet. For example, 20% of additional

stream bandwidth can result in enough

redundancy so that entire groups of

lost packets can be recovered without

ever requesting or waiting for a resend.

LRT uses a dynamic version of FEC,

meaning that it automatically varies the

FEC parameters based on monitored

network conditions.

Acknowledge and Resend

LRT uses a form

of acknowledge

and resend that

is appropriate to

streaming video and

audio. It can acknowledge large

groups of packets if they all arrived. If

some did not arrive, it can inform the

streaming engine to resend needed

data. By acknowledging large groups

of packets at a time, the overhead and

latency of TCP is not re-introduced.

Only the packet numbers are used to

let the system know what was delivered

(or not) so that only the data that is

absolutely needed is requested and

resent. You also never encounter the

main drawback of UDP where you can

only hope that your data makes it to

its destination. With LRT, you get a

complete feedback loop so you know it

is consistently getting there.

Tight Encoder Integration or Adaptive Bit Rate Encoding

The last but

perhaps most

important piece of

the LRT protocol is its tight integration

with the encoder. As the bandwidth

condition changes, LRT automatically

recognizes this and informs the video

encoder to allow it to adapt the bit

rate of video it is delivering and keep

the best possible stream within the



available bandwidth at any given

moment. This ensures you are not

trying to push more bits than will fit

on the pipe and minimize buffering.

As bandwidth conditions improve,

LRT signals the encoder to modify its

parameters and increase the bandwidth

it is using to stream. In this way, you

continue to push the best possible video

stream at all times. This backward

flow of information ensures that video

continues to be sent, and sent at the

highest quality and lowest latency

possible no matter how unpredictable

the network conditions are.

BRINGING IT ALL TOGETHERFreedom and mobility are necessary

for creating engaging live content. High

quality and reliable streams are essential

to the viewers’ experience and erratic

networks and unpredictable Internet

bandwidth can be a fear of the past with

the right reliable transport protocol

and encoding system. Especially if it is

something that happens automatically

without needing your interaction.

Bonding greatly improves available

bandwidth in the field and reliable

transport protocols enhance bonding

and quality anywhere. When the

transport and encoder engines are

integrated, all you have to focus on is

getting great content.

All LiveU online streaming solutions

allow you to acquire exciting live

content in even the remotest locations

for your viewers and deliver this content

reliably without worry. With an LRT

integrated solution, the highest quality

content streaming is ensured and you

can expect the best possible online

video experience for your audience –

differentiating your content from

everyone else.

LIVE EVENT PRODUCERS: WHAT’S IN IP FOR YOU?

Let’s face it: Live streaming pros

are far ahead of the bell curve when it

comes to implementing video over IP.

Between RTMP, MPEG-DASH, AAC,

and H.264, most streaming pros can

recite the alphabet of IP standards

f luently, encoding and transporting

their programs from wherever the

event is taking place to the very screens

where their viewers are watching it live.

Over in the broadcast world,

meanwhile, your compatriots are haggling

over which proposed standard is going to

replace SDI with a different kind of cable.

Or which development to place their

bets on when they re-wire their studio or

build out their next facility.

Or which manufacturer’s

consortium they’ll side with for signal

routing and switching.

These are the decisions they

need to make so they can migrate

their installations away from

legacy baseband—technology that

carries the outdated burdens of

inefficient weight and a low ceiling for

performance improvements. (Not to

mention a colossal pain in the gear for

disconnecting, moving around, and

reconnecting equipment at will.)

These are largely avoidable problems

for live event producers, whose client

base (or job) counts on them to be

nimble and moveable enough to detach

from the confines of a fixed studio

installation and sit in the same room

with the cameras they’re switching.

After all, if you’re reading this guide,

chances are:

• You cover events in conference

centers, meeting halls, auditoriums,

and arenas—not confined to

installed control rooms.

• You determine, mostly, where the

ideal camera placement is, and set

up your production desk where the

cables can reach.

• You are self-sufficient in your

routine to lift, transport, and

reconnect your production kit—it’s

what you do; your package may even

be part of the reason you get jobs.

• You’ve fine-tuned your system

to its most streamlined no-brainer

setup, connect, and strike

processes already.

• You don’t own a station group

with a handful of affiliates sharing

your video content and requiring a

common, standardized format.

• And your method for transporting

video signals is entrenched in

IP already.

To hear the major trade groups

tell it, the most important functions

to innovate with IP are in the areas

you don’t have a problem with—

cable replacement, proximity, device

connection, file format standardization,

transport.

NewTek’s NDI— Giving Live Event

Producers Video Over IP



If that were the extent of it, then you

might feel live event pros have been

excused from the discussion.

In reality, though, the broadcast

industry’s narrative about how IP will

improve the next generation of broadcast

and facility infrastructure barely

scratches the surface of professional video

production that’s being done out there.

BEYOND POINT-TO-POINTTypically, SDI systems, and the

IP workflows designed to replace

them, utilize point-to-point network

connections that send a signal

directionally from a video source to

its receiving destination in a one-way

path. Both models are heavily

dependent on expensive high-speed

infrastructures. That’s why they have

enormous buy-in from broadcasters:

it’s a model they have great familiarity

with already.

At NewTek, our developers believe

this minimizes the gains of true network-

based production.

In a universe where anyone reading

this guide can build a network of

computers and servers that connect

with each other and interact with them

over basic Ethernet, it seems clear that

limiting video production to a simple

point-to-point transmission vastly

underutilizes the great potential of a

connected workflow.

Indeed, on small home or corporate

LANs, people move files around, upload

or share media, and use apps to execute

a variety of tasks online … even host

games and compete with others in a

different room.

Imagine if you could open up the

same breadth of connected capabilities

by adding a network switch to your

production kit (or connecting to the

venue’s LAN where your event is taking

place)—then add any video-enabling

device you could conceive of, as long as it

was connected to the network.

That’s the promise of NDI, a bi-

directional standard that can operate

over a GigE local area network, with many

video streams on a shared connection.

INTERCONNECTED IPNDI™ (Network Device Interface) is

a protocol created by NewTek to make it

easy to share video—not just send it—on

a local area network.

NDI allows multiple video systems to

identify and communicate over IP, and

to encode, transmit and receive many

streams of high quality, low latency, frame-

accurate video and audio in real-time.

It can “IP-enable” nearly any kind

of network-connected video device you

have in your kit, including video mixers,

graphics systems, capture cards, and

other equipment.

Most importantly, it can free you to

explore a stunning range of IP workflows

that don’t emulate a broadcast facility

production process, but break out into

the live events you cover—and pretty

much anywhere you go.

BEYOND THE FACILITYFor professionals streaming live

events far from the confines of a fixed

installation, NDI can currently be

implemented in one of four ways:

• as any of several software client

applications, described below;

• as a programmable SDK freely

available for manufacturers, end

users, and developers to customize

their own IP workflows;

• as supported 3rd-party devices

connected to the network;

• or—for owners of NewTek TriCaster—

included in the TriCaster Advanced

Edition add-on software.

Regardless your live streaming kit, if

you make some standard IT networking

components part of your gear (or a good

LAN part of your location requirements),

you can use NDI to start with very

some small steps that make a really big

difference in the show you’re delivering.

Additional InputsWho hasn’t needed just one more input

at one time or another? You don’t have to

directly attach devices, wrangle cables

when moving around, or sacrifice sources

for limited hardware inputs. You can even

borrow inputs from other switchers in the

venue and switch them from a different

location, all over the network.

Source accessYou have a fixed number of

hardware devices on hand to connect

to a switcher. But what about video

sources on a network? Whichever

ones you can think of, if you have an

NDI-enabled workstation capturing or

playing them—whether from media

players, camcorders, even presentation

software—you can switch them.

Multiple roomsSay you’re covering the general

session, and your second operator is

streaming the breakout panel. If both

of your NDI-enabled switchers are

connected to the LAN, you can access

each other’s output and mix it into your

shows. What’s more, you can use any of

the cameras or other devices connected

to each other’s switchers—devices don’t

have to be on the LAN, if the switcher

they’re connected to is.

Central ISO recordingWhether it’s one multi-camera

production or several across a venue, you

can record all NDI sources connected to

the switcher, used in the program, or just


There’s an NDI production app for that

Third-party devices. Home-grown production kits. A laptop and some capture cards. Or a complete, non-NewTek,

non-IP workflow. Whatever your production gear entails, before you go spend money on an expensive network-based solution, try NewTek’s free, paid, and trial apps that put any live event producer on the easy path to IP. (Though specifications occasionally change, the below information is current as of publication. See www.newtek.com/NDI for details.)

NDI Connect Pro:This production app is a multi-purpose software client that allows you to configure a host computer as a multi-channel video server, complete with professional color correction tools, 8-channel audio control, production utilities, and support for capture cards from AJA, Blackmagic Design, DELTACAST, and other manufacturers.

Install the NDI Connect Pro client on a compatible computer on the network, and make up to 4 of its video sources appear in your NDI-enabled production workflow. Access the I/O of any cameras, decks, and devices connected to it via capture card, serve up stored media files for live playback, or increase your camera count with local webcams. Any compatible source on the computer with NDI Connect Pro installed can be configured and made available over the network to TriCaster® and other NDI systems.

NDI IsoCorder ProExpand recording capabilities to capture more productions, media files, and raw footage with recording over IP. Install this app on any network-connected workstation for multi-channel ISO recording of NDI sources. NewTek NDI IsoCorder™ Pro encodes video in a high-quality QuickTime format that’s universally compatible with practically any platform or application. It allows for virtually unlimited recording with suitable storage media and capacity.

NDI Transmit (also in Demo Version, watermarked)Upgrade your video conferencing and communications, replacing low-quality webcam video with high-quality NDI using NewTek NDI Transmit. Download and install this app on any network-connected PC to make NDI sources available for use with video-compatible 3rd party software supporting a webcam input.

Applications for NDI Transmit can include Google Hangouts, GoToMeeting, WebEx, Skype and other video messaging platforms, plus streaming encoders that support webcams.

NDI Group Editor Just as NDI allows all devices on a network to identify and use each other as sources, NDI Group Editor lets you manage which ones are and are not accessible during production. Organize NDI sources into groups and determine whether those sources are public or private on your network—making devices visible to every system, or only to certain groups. You can also determine the sources and groups that are visible and accessible to your system during productions.

NDI Scan ConverterTake full advantage of an IP production workflow with the power to switch more content into your shows—without extra equipment—using the NDI protocol, NewTek’s innovative Network Device Interface technology.

Expand your entire workflow, virtually, with the NDI Scan Converter. Install on laptops and workstations—anywhere on your network—and any combination of windows, applications, webcams, or the entire selection become available as switchable video sources, without effecting other actions on those computers during production.

NDI Test Pattern Generator Equip your system or device to send a reference signal to other NDI-enabled devices on your network for audio and video calibration. Install this app and choose from a variety of test patterns and color bars—and include an audio tone—to ensure accurate color properties and appropriate sound levels.

NDI Video MonitorTurn any laptop or workstation into an NDI Video Monitor. Install this app, then select any NDI source visible on your network to view its video feed in real time from a dedicated window on your desktop.

NDI VLC PluginEnable more content, in more formats, delivering video clips to the network directly from your desktop with the NDI VLC Plugin. Reduce the time and effort spent transcoding and transferring files for live production, bypass the hassle and cost of signal conversion from consumer devices, and access otherwise unusable content for your live programs. And all of it transcoded, transferred, and accessed over a standard GigE network connection.

available and playing on the network—

all to a central workstation for storage,

archive and later postproduction.

Allow other use of sourceBecause NDI is not point-to-point

but multidirectional, anything on

the network that can process a video

signal, not just a switcher, can use

each source—even at the same time.

A connected computer can use an NDI

feed as a Skype source, so you can send

a high-quality camera signal in place of

a low-quality webcam to a conference

room or remote meeting audience.

Device doesn’t have correct I/OFinally you can find a use for gear

that doesn’t match your switcher’s I/O

configuration. If you connect a capture

card to a workstation, and put that

workstation on the network—then you’ve

magically added an extra “input” to your

production and can be more flexible and

spontaneous with last-minute changes.

Monitor everything on the LANInstead of stringing cable for every

monitor of every camera, source, and

program out for every room in the entire

venue, all inputs and outputs of an NDI

source (including cameras connected

to an NDI-enabled switcher) can be

monitored on the network—even using

a browser. Keep an eye on everything

while walking around with your iPad.

It doesn’t take much bandwidth—

see http://bit.ly/GettingStartedNDI

for guidance. Even on a GigE network,

an NDI-enabled workflow will add

incredible capabilities at your event;

the more robust your network, the more

powerful your productions can become.

The worship landscape has changed

in recent years. Instead of building one

main megachurch, churches of all sizes

are expanding their reach to multiple

locations. As more churches go multi-site,

there is a great demand for live, high-

quality, and error-free site-to-site video

distribution that allows these churches to

reach more people than ever before and to

give the impression that the head pastor

is actually presenting at each venue.

Traditionally, this capability has only

been possible through satellite broadcast

or fiber transmission. However, satellite

broadcast distribution is expensive and

out of reach to all but the largest churches.

While fiber is more affordable than

satellite, it too is cost-prohibitive to many

churches wanting to ensure everyone

at every site hears the same message.

Of course one affordable, yet highly

inconvenient and inefficient, alternative

is to record the service onto a portable

storage device and then physically drive

it over to the other campus for later

playback — a cumbersome process that

means the congregants at the satellite

campus miss out on the live service

experience. Now, there is an affordable

real-time solution for churches:

streaming over the public Internet.

With advances in IP streaming

technologies and IP infrastructure, even

the smallest congregation with a modest

budget can stream high-quality HD video

between sites. Houses of worship (HOW)—

and many broadcasters for that matter—

are still unaware of the high-quality

service they can achieve with the latest

IP solutions. Utilizing this technology,

VITEC’s IPTV House of Worship Solution

enables HOW to extend their reach across

multiple campuses and foster a sense

of community among church members

who attend services at different sites. The

solution bundles VITEC portable encoders

and decoders—the same technology that’s

used by broadcasters, NASA, and some of

the largest stadiums in the world—with

the Zixi™ error-free streaming protocol,

and is just as effective and far more

affordable than satellite or fiber-based

streaming services, making it accessible

for churches of any size.

VITEC’s encoder/decoder combinations

with integrated Zixi Stream Protection take

advantage of an increase in bandwidth

and a decrease in costs by using the public

internet to enable real-time streaming

of church services and events. VITEC’s

portable appliances encode and stream

up to 1080p60 video for the highest level

of HD video quality at the lowest possible

VITEC Mastering Live Streaming:Solutions for Houses of WorshipBy Mark D’Addio, VP of Business Development & Emerging Markets, VITEC

The Bridge Christian Church has installed VITEC’s IPTV House of Worship Solution for affordable error-free, low-latency streaming between its two campuses in Tucson, Arizona.


latency. Combined with VITEC’s advanced

video compression, the hardware ensures

that the most demanding video will look

great even on the largest IMAG screens

while Zixi error correction protects the

stream from packet loss as it’s transmitted

over the public Internet.

VITEC/Zixi live-streaming solutions

are available in three different bundles

to enable point-to-point, bidirectional,

and multisite streaming. The point-to-

point streaming bundle includes a VITEC

encoder and decoder with integrated

Zixi Stream Protection for zero-error

delivery over unmanaged networks.

The bidirectional streaming solution

includes two sets of VITEC encoders and

decoders—one set per location—and

integrated Zixi Stream Protection. This

solution ensures low-latency streaming

for natural two-way communication

and live interaction between the main

and satellite campuses. The multisite

distribution bundle consists of a VITEC

encoder at the main campus, a VITEC

decoder at each of the satellite campuses,

and a Zixi Broadcaster platform in the

middle. Zixi Broadcaster acts as a central

hub that manages, processes, and

distributes content in various formats.

Zixi Broadcaster also makes it possible

for a HOW to record streams and play

them out later to other campuses.

Let’s take a look at one church that

utilized VITEC’s IPTV House of Worship

Solution:

The Bridge Christian Church is

a non-denominational church with

two campuses in the greater Tucson

area. The church’s goal is to offer a live

experience for the congregation at both

campuses simultaneously. To that end,

The Bridge streams services between

the main and satellite campuses so that

worshippers can experience the service

in perfect synchronization, with the aim

of providing both flawless video and low

latency so that the streaming experience

is as smooth as possible. The technical

team at The Bridge had been looking for

a more affordable way to connect the two

campuses by seamlessly live-streaming

services and events from the main church

to the satellite, or vice versa.

To make seamless bidirectional

streaming a reality, The Bridge installed

a VITEC MGW Nano HD encoder and

MGW Premium HD decoder at each

location. VITEC offered a balanced

combination of high quality and low

latency that is ideal for both point-to-

point streaming and two-way, interactive

streaming, both of which The Bridge does

regularly. The Bridge uses the VITEC

solution most often for point-to-point

streaming, whereby the output of the

TriCaster system at the main campus is

fed into the MGW Nano HD encoder for

streaming to the MGW Premium decoder

at the satellite campus. In this way, The

Bridge congregants at both campuses

experience the Sunday service in parallel,

fostering a sense of community.

Perhaps in the future holographic

technology will provide an even more

realistic experience, but until then, by

utilizing the best encoding and decoding

technology to stream over the public

Internet, houses of worship can ensure

the very best, high-quality experience at

a price point many churches can afford.

ABOUT VITECVITEC is a leading worldwide end-to-end video streaming solutions provider for broadcast, military and government, enterprise, sports and entertainment venues and houses of worship. Combining broadcasting with live streaming capabilities, VITEC’s H.265 (HEVC) and H.264 offering is the most extensive in the market with encoding and decoding appliances, IPTV Solutions for desktops and mobile devices, and PCI cards with SDK for integration projects. VITEC’s intuitive digital video solutions can be tailored to each customer’s unique market needs, delivering easy-to-use technology that ensures high-quality, low-latency HD video, capturing live and recorded events for seamless distribution in a multitude of formats anytime, anywhere, to any device.

In keeping with the company’s tradition of innovation, VITEC is the first company to bring bandwidth-efficient HEVC compression technology into the field with portable streaming appliances.

RECORDING VITEC’s House of Worship Streaming Solution is now integrated with Renewed Vision’s ProVideoServer (PVS), a four-channel HD video server. This partnership furthers the capabilities of VITEC’s end-to-end streaming solutions by adding recording, playback, and time-slip capabilities, allowing churches with multiple campuses to tailor their broadcast services to the needs of their satellite campuses. The time-slip functionality, much like a DVR, allows for the immediate playback of a video even as it continues to record from the main campus. For churches streaming more than one camera feed, the synchronization capabilities of PVS, along with VITEC’s encoding and decoding technology, allow both camera angles to stream at the highest HD video quality and at the lowest possible latency to the remote site, making it an ideal dual-input, dual-output time-slipped media record and playout server.

BENEFITS• Real-time video delivery

between the main church and the satellite campus

• High-quality streams up to 1080p60 for pristine video even on IMAG screens

• Low-latency encoding and streaming with delays of less than two seconds

• Zero-error Internet delivery with Zixi™ Stream Protection

• Ability to use public Internet for significant savings over satellite and fiber solutions



Video streaming is very popular.

Advances in computer networking over

the past couple decades, combined with

powerful home computers and modern

operating systems, have made streaming

media practical and affordable for

ordinary consumers. And as the demand

for video streaming grows, so does the

number of best streaming software

options to service that demand.

Live streaming requires several

components:

• a form of source media (e.g. a video

camera or a video game console),

• a capture device (if the source is

external), such as the Epiphan AV.io

video grabbers

• an encoder to digitize the content,

• a broadcast platform (e.g. YouTube),

• and sometimes a content delivery

network (CDN) to distribute and

deliver the content (to improve your

user’s experience in terms of speed).

Streaming software is an integrated

broadcast solution that facilitates the

live streaming process by combining the

capture, encode and publish steps into a

single application, letting users stream

their source video content to a variety of

platforms, like YouTube or Twitch.

Consumers and businesses alike are

using streaming software solutions with

their source content to live stream their

content to inform, persuade, entertain, or

simply communicate with their audience.

But how many different streaming

tools are out there? A whole lot, as it

turns out. And what’s more is that all

of them work with Epiphan’s AV.io

video grabber products. But Telestream

Wirecast® software is the only cross-

platform, all-in-one live streaming

production software. When you need

to live stream to large online audiences

and be able not just to capture, but add

production capabilities, including sound,

transitions, virtual sets and scoreboards,

then you’ll want to use Wirecast. With

Wirecast you can capture your cameras

or devices using Epiphan video grabbers

or broadcasting and recording products,

then pull them all together in a easy and

affordable way for your online audience.

Create professional-looking news, online

gaming, internet shows, sporting events,

concerts, church services, corporate

meetings, lectures, and more.

The Epiphan AV.io devices are about

the size of a pack of cigarettes that attach

to your computer or laptop, PC or MAC

via USB3. They are bus powered and

do not require any special drivers. You

can use them easily with Telestream

Wirecast or any other software program

including Open Broadcaster, vMix, XSplit

Broadcaster, VIDBlaster, and more—and

they just work! Allowing you to bring

in HDMI or SDI footage and stream it

live over the internet. Epiphan AV.io HD

video grabbers automatically adjust

video scaling and aspect ratios based

on your application’s requirements,

providing you fantastic video quality—

even when swapping video sources.

Together, the Epiphan Av.io grabbers

and Telestream Wirecast software allow

you to produce a live 2-camera shoot

from any Mac or PC, laptop, or desktop

for only about $1,000!

These systems can be set-up quickly

and easily in just a few easy steps:

How to Stream Multiple Cameras Live With Your Laptop and Wirecast Studio

lagging transmission, but will enjoy a

great game. You can add screen sharing

for remote presentations, on Windows,

MacOS or even Android. Additional

features like networking statistics,

live metadata, and overlays, external

cameras, GoPro and Drones, can be

used for seamless integration into

professional broadcast environments.

Journalists use nanoStream to directly

stream live videos of current events from

their own apps. Our software guarantees

media companies full control over the

content, for fast and safe broadcasting of

breaking news.

The world is moving quickly towards

a single melting pot of creating and

consuming live video. Despite many

different standards, formats, operating

systems and browsers, we enable any

event to be live encoded, streamed, and

played back with low latency on any

device, anywhere!

But video is hard. How can you roll

out live video services successfully,

across multiple platforms—desktop,

mobile, and browser? Here are different

key challenges you might face:

• Live encoding: how to obtain a perfect

camera signal and send it to the

internet, even in unstable networks ?

• Live streaming and delivery: how avoid

complicated server setup, installation

and maintenance processes?

• Playback: how to achieve the

best possible user experience for

your communication partner or

live audience?

Tell Your Story With Live VideoSimplify creating cross-platform live streaming apps


• Instant streaming: avoid encoding

and streaming startup delays for

immediate results for breaking news,

music, sports, celebrities, etc.

• End-to-end low latency to enable live

video communication applications.

• Be flexible to use cloud or

on-premise services.

• Allow live video broadcast and

playback on any device, independent

of vendor and OS.

HOW TO CREATE YOUR OWN LOW-LATENCY LIVE STREAMING APP WITH THE NANOSTREAM SDK IN 5 MINUTES

This is a short overview showing

how you can get a headstart on your

competition for your end-to-end

streaming platform by leveraging proven

nanoStream technology.

See how easy it is to create your own

high quality end-to-end live encoding,

streaming and player application!

With this guide, you will be able

to create a live video broadcaster and

player app with the nanoStream SDK,

connected to our bintu.live streaming

platform. You do not need to install your

own server, just stream instantly to the

URL you get from bintu.live!

You will still be able to use your own

server on your own premises if required.

Requirements• nanoStream SDK 4.6 or later

• bintu.live connector

• a valid bintu.live API key and a

nanoStream SDK license

• Development Environment: you can

be completely cross-platform!

• iOS and MacOS: XCode on Mac OS X

• Android: Android Studio or Eclipse

• Windows: VisualStudio 2013 on

Windows 7 or later

• Browser Platforms: HTML/JS for your

own web page based on either our

nanoStream Plugin or WebRTC Client

Build your Live Encoder App (Broadcast)How to build the broadcaster (this is

for iOS but similar projects are available

on all platforms)

• Open the project StreamingExample

from the SDK samples/SimpleEncoder

folder in Xcode.

• Add the license and API keys in

nanoLicenseConfig.h (folder include)

• Build and run the application.

How to use the broadcaster• Enter your API key

• The app is checking the bandwidth,

either wait or skip to use default

• Tap the “start” button to start broadcast

• You should see the result logged to the

console: “You are live!”

The streamer automatically gets a

stream URL from bintu.live and instantly

starts live streaming.

Player App• Open the project PlayingExample

from the SDK samples folder in Xcode.

• Build and run the application.

(your license and API keys should

be used from the same file as the

broadcaster app)

If you tap the play button, you should

instantly see your live video sent from

the broadcaster device!

You can do this easily

on any platform with your own

preferred system environment!

SUMMARY Congratulations! You now have

everything you need for your own

streaming platform.

You can now run the broadcaster

app on one device and the player app on

another. You can start a stream in the

broadcaster app (via Start button) and

can play it directly in the player app (via

Play button). The player app assumes

that you want to play the latest stream

on your account that is live.

NEXT STEPSFrom here on you can integrate the

live streaming function into your own

application backend. If you want to know

more how these sample apps were created

and how you can set up your own ones,

contact us or read our step-by-step tutorial.

For a more complete sample apps on

how to use nanoStream and bintu.live, see

the samples BintuEncoder and BintuPlayer

in the SDK samples folder. They show a

complete workflow including bandwidth

check, user notification, sharing, vertical

and landscape streaming, and more!

You find similar samples for Android,

Windows, MacOS, and browser platforms.
