Mobile Video Telephony: For 3G Wireless Networks

Description

According to EMC, mobile data subscribers broke the 1 million barrier in September 2003 and hit 115 million in January 2004, the market a mix of streaming video players like RealNetworks and 3G wireless operators, who have invested heavily in video and constructed their infrastructure accordingly. The current fad for photo-phones has demonstrated the potential market for more elaborate video, whether downloading video clips for entertainment, game-playing, or video calls. This is a system level design book aimed at the engineers deploying mobile video services around the globe. Pulling the relevant pieces from the many confusing standards and protocols surrounding video telephony, the book serves as a roadmap through the regulatory maze, as well as a detailed tutorial on each phase of deployment, from video compression through multiplexing and call control.
