Method and device for ensuring reliability during transmission of television data in a television system based on internet protocol

摘要

A coding/transmitter device (11) includes a broadcasting module (12) in order to broadcast television to a plurality of STB receiver/decoder devices (15) via an IP/Internet network (14), so that the clients-subscribers are provided with a first UDP stream and a second UDP stream which includes identification data associated with data packets transmitted within the first UDP stream in order to provide functionalities such as reorganisation of packets, detection of losses, requests for retransmission etc. without adding headers according to the RTP protocol, but with a reliability and capability of inserting additional data comparable to that provided by the RTP protocol.
