Trends Driving IPTV Adoption
 Subscribers want more choice and control
New generation grew up computer/Internet savvy
Customized for me – One bill, one provider, integrated services
 Codec, access, server and CPE technologies are improving
MPEG-4 AVC (H.264) improvements, new xDSL, FTTx, DOCSIS 3.0 access technologies
Moore’s law advancements in processing and memory
 Competition is increasing among service providers
No longer limited by access
Traditional markets are going away, e.g., VoIP is almost free
Video is driving next generation service provider network designs
