Method and devices for processing and reestablishing multimedia streams

A non-transitory computer readable medium encoded thereon a computer program, said program including instructions when executed by a processor used to implement a process performing:

• reproducing a first stream on a reproduction terminal;
• interrupting reproduction of the first stream and reproducing a second stream on the reproduction terminal;
• associating with each stream a preference indicator specifying whether the corresponding stream is a principal stream or a secondary stream;
• and
• recording the first stream simultaneously with reproduction of the second stream if the first stream is a principal stream;
• the process further including an initialization step during which a stream table is created, the stream table including a preference indicator assigned to each stream, wherein a priority level is assigned to each entity in a group formed by the user, an application server, and stream suppliers, in the course of which, the process further includes the steps of:
• When updating the stream table, a preference indicator and a modification indicator are assigned to each stream;
• a preference indicator in the stream table is updated by the application server only if the priority level of the entity which demanded the update of said preference indicator is higher than the modification indicator associated with the preference indicator to be modified;
• then if an update has been implemented, the modification indicator associated
• with the updated preference indicator is replaced by the priority level associated with entity which demanded the modification.

A system for automatic processing of multimedia streams, including a terminal for reproduction of streams and a means of control to enable a user to interrupt the reproduction of a first stream and to demand the reproduction of a second stream on the terminal, the system further comprising:

• means for managing streams in order to associate with each stream a preference indicator specifying whether the corresponding stream is a principal stream or a secondary stream;
• means for recording the first stream simultaneously with reproduction of the second stream if the first stream is a principal stream;
• means for initializing the creation of a stream table, the stream table including a preference indicator assigned to each stream;
• means for assigning a priority level to each entity in a group formed by the user, an application server, and stream suppliers;
• and
• means for updating the stream table,
• wherein, when the stream table is updated, a preference indicator and a modification indicator are assigned to each stream, a preference indicator in the stream table is updated by the application server only if the priority level of the entity which demanded the update of said preference indicator is higher than the modification indicator associated with the preference indicator to be modified, and if an update has been implemented, the modification indicator associated with the updated preference indicator is replaced by the priority level associated with the entity which demanded the modification.
