Broadband Value-Added Services
High Growth for Video and IPTV expected
Television pictures in 3-DimensionsViewers can see real depth without aids such as shutter orpolarisation spectacles... The aim of the collaboration is to produce live images at the Football World Cup 2006 for the pilotsets
Worldwide subscribers to Digital Video Recording (DVR) services will rise by a factor of seven between 2005 and 2010
Market will reach 83.4 million users in 2010, representing a compound annual growth rate (CAGR) of 45.3%, from 12.9 million in 2005, according to iSuppli
