Method for the transmission of audio contents in a hybrid receiver, system, receiver and program associated with the method
A method of transmitting an audio and/or audiovisual content to a receiver. The method starts with receiving a determined stream broadcast on a network and playing back the contents transmitted by the stream in the receiver. Then a first event external to the receiver is detected and triggers interruption of the playback of the content in progress and recording of the instant of the interruption. Sometime later, a second external event triggers a transmission, from the receiver to a remote server, of the instant dating the first event and of a request for resuming the playback of the interrupted content. A piece of information specifying the identifiers of the data packets of the content at the instant of the interruption is then transmitted from the remote server to the receiver. Finally, the receiver receives the identified data packets and replays the content of the packets. |
