Abstract:
1. A method for improving a channel change response time, comprising: generating, from an original media stream conveying media content, at least one auxiliary media stream, each of the at least one auxiliary media stream conveying the media content of the original media stream, each of the at least one auxiliary media stream being offset in time with respect to the original media stream wherein, for each of the at least one auxiliary media stream, the auxiliary media stream is generated in response to a channel change request received from one of at least one user terminal; propagating the media streams toward at least one user terminal using respective multicast groups; generating a meta channel associated with the media streams for conveying information adapted for use in selecting one of the media streams to thereby improve the channel change response time; and propagating the meta channel toward the at least one user terminal.
