4. Addressability: Growing into new customer segments Today+ HSInew PC servicesBeyond PC DSL dial-up Conversion Non-internet PC conversion Non PC conversion Broadband Penetration (% households) Europe: typical penetrations 5-15% have already broadband Sequentially address different population segments 100% 50% 25% 75% 3. New services over PC 30-60% have a PC 4. Beyond PC TV sets Videophony ~100% have a TV set 2. Flexible pricing & bandwidth management 20-40% are on the web natural DSL potential 15-30% have broadband potential 1. Aggressive marketing Source: Alcatel

10. 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

11. >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 IPTV Triple Play Technical Considerations - 2

21. 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.
