METHOD FOR RETRANSMISSION OF A MULTIMEDIA STREAM, FROM A VIDEO TRANSMITTER, VIA AN INTERMEDIARY SERVER

摘要

Method for retransmission of a multimedia stream from a video transmitter via an intermediary storage server, this multimedia stream comprising packets coding independent images, and packets of dependent images, the multimedia stream comprising a continuous component and a discontinuous component, the intermediary server storing this multimedia stream in a memory characterized in that it comprises the following steps: - the step for the intermediary server to receive a request for retransmission of the multimedia stream transmitted - the step for the intermediary server to select an independent image packet stored in its memory in order to begin a retransmission of the received multimedia stream and - the step for the server to accelerate the retransmission of the multimedia stream received later than the independent image packet selected omitting to retransmit the dependent image packets until the accelerated part of the stream retransmitted by the intermediary server is synchronized with the stream received by this intermediary server, wherein the retransmission of the discontinuous component is accelerated while the retransmission of the continuous component is carried out, without acceleration, from a continuous packet stored in the server in such a way that the continuous component is synchronized with the discontinuous component retransmitted when the stream retransmitted by the intermediary server is synchronized with the stream received by this intermediary server.
