This examines three main classes of components that will have a major effect on the deployment of IP TV: VDSL, Fiber to the Premise (FTTP), and Video Compression/Decompression (codec) Components. The VDSL and FTTP components improve the performance of IP TV networks by increasing the bandwidth provided to each subscriber. The Video codec components improve the performance of IP TV networks by lowering the bandwidth required to transmit video streams to subscribers. Specific components covered include VDSL-1, VDSL-2, APON & BPON, EPON, GPON (transmission); and MPEG-2, Windows Media 9/VC-1 and MPEG-4/H.264 (codec) chips. Nine suppliers are profiled, including Aware, Texas Instrument, BroadLight, Equator, LSI Logic, Sigma Designs and others.

The report shows that: VDSL will be important for IP TV because it supports HD (High Definition TV); GPON (Gigabit Passive Optical Network) will not be ready for volume deployment until 2006; set top boxes supporting all three codecs will be available for deployment in 2005; and FTTP (Fiber to the Premise) will also gain importance under certain conditions.

The report compares the three new VDSL and four new FTTP technologies with the current ADSL and the new ADSL-2+ technologies (deployed in 2005). It also compares the bandwidth and distances required by each of the eight transport technologies to support IP TV video streams for both Standard Definition (SD) and High Definition (HD) TV (using all three codecs). Other issues crucial to developing future IP TV infrastructure business cases are also investigated.

Although the report focuses mainly on the downstream speeds, it also explains how ADSL ? 2+ (the slowest of the new transport technologies) supports more than 1 Mbps upstream-- fast enough to eliminate upstream latency for channel changing, or any other system performance requirements.
