Abstract
A method of switching over an audiovisual session involves receiving a request for session switchover to a second access network, emitted following a change of a state of attachment of the terminal; ordering switchover of the audiovisual session from a first output interface to a second output interface at a data stream gateway; recovering information related to a context of the audiovisual session switched over to the second interface; ordering evaluation at a contents profiles server of an adaptation of quality, that can be supported by the second interface; and requesting an update of the data stream to ensure the quality adaptation.
