Abstract
The invention relates to a method of managing a plurality of multimedia sessions involving user terminals connected to an access point of an IP network including at least one collection node when at least one audiovisual first session is in progress during which a first user terminal receives an audiovisual content encoded in the form of a plurality of SVC audiovisual streams via a link between said access point and said at least one collection node. The method of the invention receives a change request relating to a second session that is one of said plurality of sessions, recovers information relating to a context of said plurality of sessions, evaluates a new distribution of resources between said first session in progress and the second session, decides to accept or reject the change request as a function of the result of said evaluation and sends a message containing its decision. In the event of a positive decision, it commands adaptation of the transfer of the audiovisual content effected on said link during the first session by modifying a plurality of audiovisual streams to be transmitted.
