Next Gen Local Content Insertion Solutions

for MDU / Institutional / Government use

2019

Agenda

We will discuss Local Content Insertion

Solutions for:

• HFC Architecture

• Fiber Deep Architecture

• RFOG

• RemotePhy / PON Architectures

• OTT and Internet based back haul

• Gate Cam App.

Locally Created Content Insertion

• Allows Residential / MDU communities to insert locally generated signage and or programming into the CATV channel lineup.

• Requires close coordination between property owners / managers, equipment manufacturers, and CATV system operators.

• Considerations:– What QAM center frequency?

– Architectural considerations (HFC/FD/PON)

– How many channels of content?

– What kind of content, High Definition or Standard Definition?

– Content Source Interface type? SDI/CVBS/HDMI?

– What channel number displayed on the box?

HFC Local Insertion – MDU Solution

1. Typically the new QAM is inserted on EIA 95-98 or in the

upper roll off band > EIA 158 (999.0MHz).

2. Attenuator is selected to place insertion QAM 0 dBc from the

broadcast carriers.

HFC Digital Content Insertion – MDU Solution

HFC Digital Content Insertion on existing QAM

1. A single QAM trapped and diverted to Demux. One program number removed.

2. Local Content encoded, new program number added, QAM remuxed.

3. Attenuator is selected to place insertion QAM 0 dBc from the broadcast carriers.

Fiber Deep Local Insertion

1. Insertion is made as an overlay QAM l

via express port.

2. Coupler and attenuator selected to place

new l -10 dBc from the broadcast l.

WDM Backhaul of MDU content for Retransmission

MDU Video is transported via IP to the headend where it is inserted into the

local service group as narrow cast QAM or IPTV service.

In this case, MDU content is transported to the headend on an

Ethernet l. Can use dedicated or occupied fiber. The content is

then inserted into a service group edge QAM.

Local Insertion – Remote

(MAC) PHY

1. Cable Modem Connection Used

2. Encoder packages and publishes

3. DNS entry made to point to service

4. Security – ACL in local FW

5. Dynamic streaming protocols are

used for OTT streaming of content

Next Gen MDU Content Hosting (OTT)

1. Dynamic Adaptive Streaming Protocols Enable MDU content to be carried as an

OTT Web Service.

2. Utilizes existing web based infrastructure

3. Uses HTTP / HTTPS protocol which is passed through firewalls by default.

4. DABR lets the client decide how much media to take based on cache, network

conditions, CPU factors.

5. Does not take up broadcast or narrowcast QAM resources.

6. Presents some security challenges, how to control who gets to see.

7. Compatible with IP Set top boxes, PC’s and smart phones.

Local Webcasting Points of Consideration

• An Encoder hosts the Packager and Web Server locally.

• A Static Public CPE IP address is required for the Encoder.

• The Encoder must be Protected behind NAT/Firewall rules.

• HTTPS can be used to secure streams with certificates

• Local Network DNS entry to allow name resolution

• Fits IPTV and Hybrid IPTV/Broadcast Architectural models

• HTTP/ABR widget required for Set Top Box access

SRT Protocol for Transporting

Video Content via the Web

1. Secure Reliable Transmission (SRT) protocol suite

1. Establishes a Caller / Listener relationship between Encoder and SRT Gateway

2. Monitors stream for packet loss and jitter

3. Replaces lost media with retry mechanism.

4. Gateway has adjustable delay to allow for packet replacement

SRT Transport Protocol

➢ SRT = Secure Reliable Transmission

➢ SRT is a Connection Oriented Protocol

➢ Control information is exchanged between SRT Nodes

➢ Latency / Overhead are Adjusted to Compensate for Packet

Loss / Jitter

➢ AES 256 Encryption of Content Streams

➢ Detailed Statistics are sent from Listener to Caller reporting on
