Abstract
A replayable TV system (100) comprises a multicast server (10), access to an IP TV network (20), a media server (30), at least one set top box (40), and a time-shift server (50). The multicast server multicasts a TV program to the media server and the at least one set top box through the IP TV network. The time-shift server controls the media server to record the program. At any time point during the multicasting of a TV program, if a set top box requests the time-shift server replay the TV program, the time-shift server sends the uniform resource locator corresponding to the TV program to the set top box. The set top box switches automatically from multicast unicast mode and receives the recorded program from the media server.
