摘要：
The present invention relates to methods and arrangements for providing an improved channel change solution for and IPTV system. This is achieved by sending an additional FCC (Fast Channel Change) media stream using multicast from a fast channel change server. The FCC media stream contains a stream being a copy of the main stream wherein the speed is higher than the speed of the main stream. The FCC media stream may start with an I or S-frame and a number of STBs can use the same FCC multicast stream.
