While data and VoIP continue to drive the DSL IC chipset market, and will account for the bulk of port shipments through 2010, the delivery of IPTV capability is the wave of the future, reports In-Stat. Carriers worldwide are using ADSL2+ and VDSL2 as they upgrade their networks to deliver television and video service, the high-tech market research firm says.

"With applications like video phone service, uploading of photos and video in addition to music, online applications from Google and others, the demand for upstream traffic is likely to increase over the next few years," said Norm Bogen, In-Stat analyst. "This means the technology able to deliver upstream bandwidth will have the advantage going forward."

Recent research by In-Stat found the following:

• In 2005, there were 153.1 million total ports of DSL shipped worldwide, including CO and CPE for ADSL, VDSL, and SHDSL.
• The number of ports shipped is expected to grow to 185.5 million in 2010.
• Revenues through 2010 will decline, however, as there is increasing pressure on price from DSLAM vendors.

The research, "DSL IC Chipsets: The Emergence of VDSL2" (#IN0602875NT), covers the worldwide market for DSL IC chipsets. It includes port shipment and revenue forecasts through 2010 by technology. It also contains analysis of standards development and major regional markets throughout the world. Data on vendor market shares for 2005 and the first quarter of 2006 are also provided.
