METHOD AND INTERNET PROTOCOL TELEVISION (IPTV) CONTENT MANAGER SERVER FOR IPTV SERVICING

摘要

There is provided a method and an Internet Protocol Television (IPTV) content manager server (312) for IPTV service. The server comprises a Real Time Streaming Protocol (RTSP) stack adapted to request an establishment of a first RTSP session with an IPTV media server (314) responsive to an IPTV service request (311) from an Internet Protocol Television Terminal (ITF 302). The RTSP stack stores (342) an identifier of the first RTSP session responsive to the request for the establishment of the RTSP session. Subsequently, the RTSP stack receives an RTSP session initiation message (360) from the ITF requesting an establishment of an RTSP session. Upon receipt of the message, the content manager server authenticates the message (356), determines the existence of an existing RTSP session for the ITF, and thus acts to discard the session initiation message received from the ITF and to return the identifier of the first, already established, RTSP session (342).
