Core Video System:Market Status
� From a core network perspective, there is scope for confusion with respect to requirements for video
Different types of video service providers and service offerings
Each type can span verticals
Different requirements and architectural options for different types of providers by vertical
Numerous technology choices for each architecture

Market Dynamics� Contribution – General move from ATM and SDH networks to IP / MPLS
� Secondary distribution
Cable MSOs
Mix IP and satellite distribution of broadcast content today
National satellite backbones moving to IP terrestrial backbones due to regulation
Convergence of IP data and IP video services
Wireline – Incumbents
Acceleration in IPTV deployments
Longer term focus on integration of disparate networks – convergence of IP data (business and residential) and IP video services on IP/MPLS backbone
Support for retail and wholesale (regulated and unregulated) services required
Wireline – Challengers
Similar considerations to incumbents, without the pressures of regulation, hence wholesale requirements less prevalent
� Next round of core/edge upgrades for many SPs will be influenced by support for video services

Video Service Requirements
� Among consumer video services, real-time streaming applications such as IPTV impose the most stringent network requirements.
� Video streaming is used both for “broadcasting” video channels, which is commonly delivered as IP multicast, and for VoD, which is delivered as IP unicast.
� Broadcast video has more stringent requirements than VoD on the core
With the general move to distributed VoD architectures, where VoD caches are located at the edge of the network, the core network is used for distribution of the content to the VoD caches in non-real time. This is essentially a file transfer capability, which has less stringent requirements on the core network than IPTV.
