Potential Triple Play Killer Apps

> Service Bundle, Single Bill, Single Service Point of Contact> Video

– Multi-casting live TV(IGMP/UDP), True VoD ( RTSP/UDP), Time-Shifting TV– Video Chat

> Voice– VoIP Voice Calls – TV Centric Telephony

• Incoming calls phone number flashed up on the TV screen > Data

– Internet TV, Interactive internet shopping, Personalized TV portals– Gaming, Music download– Email, Instant messaging

IPTV Triple Play Technical Considerations - I

> IGMP - Improves Channel Change Speed

– Use for end to end channel change from the CPE to the core network

> Multi-casting for live TV programs to avoid network congestion between the Headend/CO and DSLAM

– DSLAM should support Multi-casting

> Single or dual stage multicasting

– If there exists DSLAM bandwidth limit, use dual stage multicasting. Designate bandwidth for default channels and consider on-demand multicast for niche channels through the IGMP request.

> Security– Allow/Deny access to services/channels based on proper customer profiles

> Digital Rights Management> Advanced Codec to reduce bandwidth requirements

– H.264– WMV9– AVS

>QoS – Must be End to End across the Entire Network

• Home Network, access network, core network and content network

– Must be Peer to Peer from OSI Layer 1 to Layer 7 – Upstream and Downstream Bandwidth Allocation

• Video – Asymmetric – VoD, multi-cast video– Symmetric – Video conferencing

• Voice– Symmetric – lower bit rate but latency sensitive

• Data– Best effort

Conclusion

> Premium Content Availability is Crucial in China for Triple Play > Integration of Video, Voice and Data is a Trend> End to End IGMP for Multicast Video> RTSP for VoD and Networked PVR> End to End QoS is Crucial to Meet User Expectation on Video

and Voice> Plan for Advanced CODEC such as H.264 and AVS > Plan for Future xDSL Technologies such as Uni-DSL

Note: Voice over cable gives the MSO the triple play in addition to video and data. TI is in a great position to support both xDSL triple play and Cable triple play.
