Subscribers to Internet Protocol TV services usually complain about one key characteristic - the additional delay digital video introduces when subscribers change channels, especially when subscribers "channel surf." The problem is traced to at least three sources of delay in a convention Internet Protocol video deployment system. The channel changing delay can be minimized by caching video packets for the most likely next channel in a buffer in anticipation of a television subscriber changing channels and/or by having an adaptable buffer length in the set top box.
