Video on demand (VOD) systems allow users to select and watch video and clip content over a network as part of an interactive television system. It is an example of converged service. VOD systems either stream content, allowing viewing in real time, or download it, with the entire program brought to a set-top box before viewing starts. The latter is more appropriately termed store and forward. The majority of cable and telco based VOD systems use the streaming approach, whereby a user buys or selects a movie or television program and it begins to play on the television set almost instantaneously.
