Fig.2. U.S. Multichannel Video Subscriber Census

Above is a figure of U.S. Multichannel Video Subscriber Census by SNL Kagan [2]. In 2011, the cable industry lost 1.8 million video subscribers whereas IPTV providers gained 1.6 million. This shows that IPTV industry is gaining market share on video content provider and it is expected to grow even more. Cable TV delivers entire line-up of broadcast content channels all the time which requires huge amount of bandwidth being delivered all the time into the home and cable companies are moving toward IPTV delivery services to reduce bandwidth on their infrastructure. IPTV architecture is very different in that it only delivers the single channel that is requested by the consumer’s individual TV. Therefore, IPTV architecture can greatly reduce bandwidth by only providing specific request from the consumer at any given time [4]. [pic]
