Video Codecs – the main ones for DMS

ITU-T H.262 - MPEG-2 Video

Widespread digital video codec. Used for DVDs and broadcast

ITU-T H.264/AVC - MPEG-4 Part 10

Approx 50% bandwidth gain for same picture quality vs. MPEG-2BluRay, broadcast, mobile video, Internet streaming

Windows Media Video

WVC1 = WMV9 Adv profile = standardised version by SMPTE

Adobe Flash Video

Actually a file container. Supports H.264/AVC, On2 VP6,Sorenson Spark




Typical Compression RatiosStandard Definition

Compressed stream is 100-180 times smaller

MPEG-2 compresses to 15-20Mbps

Compressed stream is 50-100times smaller




MPEG-4 Encoding and MPEG2 TS

MPEG-4 is transport agnostic, i.e., does not definetransport layers; adaptation to a specific existingtransport layer has been defined

MPEG2 transport layer

Multiplex PES streams belonging to the same program(video, audio, teletext, subtitles)

Provide program synchronization (PCR)

Produce a Transport Stream (TS) of fixed length

(188 bytes) packets

1. Setup Cisco Hinter 2. Setup Darwin Streaming Server

3. For each video, use Cisco Hinter to hint the video andproduce a [video].mov file. This small [video].mov file

tells DSS how to stream the underlying [video].mpgfile, without caring about the video and audio codecs

4. This .mov file must be put on the serving directory ofDSS, along WITH the original content [video].mpg

5. Stream can be requested with following URL:rtsp://DSS-ip:<optional port>/[video].mov

The WAE streaming server supports the unicast-in multicast-outstreaming

The unicast input is from DME 1100 and DME 2200 encoders

The ASF header obtained from the unicast input and the parameters used toconfigure the multicast station are used by the WAE streaming server to

automatically create the multicast description file, i.e., .nsc file

The client PCs use the .nsc file to subscribe to the multicast

Show and Share appliance options

Show and Share Video Portal is packaged in two options:

1. Show and Share Workgroup – Ideal for a variety of use casesthat feature smaller workgroups within an organization.

2. Show and Share Enterprise – Offers support for organizationsthat want to enable large numbers of authors to create and publisha variety of a content that will be accessed organization-wide.

Solution Option Use Case Recommendations

Show and Share Workgroup

(WAVE-574)

― Less than 3000 total authors

― Up to 50 authors creating content at the same time

― Primary usage is content viewing

Show and Share Enterprise

(MCS-7835H3)

― More than 3000 total authors

― Up to 175 authors creating content at the same time

― Mixed usage of authoring and viewing

scheduler • Multiple playlists/presentations downloaded

• Support for Flash and USB external drive

• System wide bandwidth limitation for each DMP download

• Differential download: no re-download of existing valid content,but changes only

• No duplicate download of content

• Detailed reporting of success/failure of downloads

DMS-CD is a framework, bringing intelligence andbandwidth optimization for content distribution to DMP

flash and external USB drive

Optimizes and caches VoDs reducingload on the WAN

WAAS Overview




Live Windows Media RTSP AO

Windows Media Player (A) request stream via RTSPT

Origin server (F) sees one stream per WAE edge

One stream between Windows Media publishing point (F) andencoder (G)

DRE for HTTP Delivery

DRE cache fills on first pass

WAN bandwidth by 90+ percent on second pass

DRE cache is FIFO and will evaporate eventually

Next client to request VoD after DRE cache evaporates will pullover WAN

Recommended for flash crowds or short shelf life video

Retain DRM if streamed over TCP

Video Server

DRE Evaporates

WAAS Video On Demand




CIFS Delivery

File cache fills on first pass

WAN bandwidth reduced by near 100 percent on second pass

If cached, file may evaporate based on LRU

Support for file pre-positioning ensures video will not evaporateregardless of how much time passes

Recommended for extended shelf life video

Retain DRM using CIFS authentication

File Server

Optimized Digital Media Delivery




With CIFS

The DMM will notify the DMPs to mount to the CIFS share

All DMPs will be mounted; it is all or nothing for this version; no option for single orgroup DMP mounting

For presentation that were created with content pointing to a URL or presentationsthat were moved to an external server will still be valid

CDS Relationship to ACNS

ACNS ACNS is a leading CDN product

which has been enhanced andextended for enterpriseenvironments

ACNS is deployed on the CiscoWAE family of appliances

CDS Cisco acquired Arroyo in October

2006 and created CDS to form themulti-format multi-protocol contentdelivery platform

A subset of the baseline ACNScode was ported over andenhancements made for serviceprovider and large enterprises

CDS is deployed on the CDEfamily of appliances
