A VIDEO ON DEMAND CONTROLLING METHOD, A CLIENT DEVICE AND A SWITCH CONTROLLING EQUIPMENT

摘要

The present invention discloses a VOD control method, a client device, and a switching control apparatus, relating to a media playing technology. The method includes: receiving VOD commands from a user, selecting and joining a multicast/broadcast channel with the playing time close to the playing start time of the video program on demand, receiving and buffering the data of the video program from a multicast/broadcast server; and judging whether the tolerance between the playing time of the multicast video program on the multicast/broadcast channel and the playing time of the video program on demand is within a threshold, and if so, playing the buffered multicast/broadcast data. The client device includes: a decoding and outputting unit, an obtaining unit, a switching control unit, a unicast control unit, a unicast data receiving and buffering unit, a multicast control unit, and a multicast data receiving and buffering unit. The technical solution provided by the present invention can implement VOD services with few server resources and network bandwidths.
