Abstract: A system and a method for protecting contents of broadcast are provided to protect the broadcasting streams of plural IPTV channels by creating encryption processes as many as the number of IPTV channels and distributing the encryption processes about the broadcasting streams of the corresponding IPTV channels. A key management sever(11) allocates IPTV channels by encryption sever by using the number and the system information of the encrypted severs according to an IPTV channel allocation request of at least two encryption severs(12), and transmits the distributed and allocated IPTV channel information and the encrypted key information to at least two encryption severs. The encryption severs encrypts the broadcasting streams of the distributed and allocated IPTV channels by using the encrypted key information, and transmits the encrypted broadcasting streams to a content reproduction device(14). A program guide sever(13) provides the content reproduction device with information as to a channel list of a broadcasting IPTV channel, a broadcasting program, etc.

Abstract: A bidirectional IPTV broadcast service method and a system thereof are provided to enable a guest to attend a broadcast remotely without inviting the guest to a studio, thereby supplying various type broadcast services. In a bidirectional IPTV broadcasting system, a broadcast controller(100) controls a bidirectional IPTV broadcast. A client(200) performs the existing IPTV STB function and simultaneously provides bidirectional IPTV broadcast services to a viewer. A platform server(400) transmits an actual broadcast stream to the viewer at a reserved time. A media server(300) controls the client participating in the bidirectional IPTV broadcast service. The media server performs a media server headend function which mixes media streams from the broadcast controller and the client.
