Video applications require large amount of bandwidth and also storage space. The Fast Broadcasting (FB) scheme is one of the simplest schemes to provide video services, but it requires considerably large buffer storage. This scheme assumes constant video popularity and thus has fixed amount of bandwidth requirement. The popularity of videos generally does not remain the same. It varies over a period of time and accordingly the bandwidth allocation should be adjusted. The variability in bandwidth requirement for videos based on popularity is overcome by incorporating seamless channel transition mechanism in a broadcasting scheme. After incorporating seamless channel transition mechanism, the scheme still delivers continuous video data to old and new users without jerks and hiccups.
