<p>The invention relates to a method for operating a statistical multiplexing of distributed video streams through a video transmission system comprising a plurality of video servers located in different places, characterized in that it comprises the different steps consisting in:
- encoding a first video stream with a first video server of the plurality of video servers to produce a first encoded video stream;
- encoding a second video stream with a second video server of the plurality of video servers to produce a second encoded video stream;
- transmitting to a central unit, through at least one network, the first encoded video stream and the second encoded video stream;
- memorizing the first encoded video stream in a first buffer of the central unit;
- memorizing the second encoded video stream in a second buffer of the central unit;
- operating, in order to produce a multiplexed video signal, a rate allocation process among at least the first encoded video stream and the second encoded video by calculating a transmission rate for each stream depending on the average quality of the memorized stream in the central unit such that a fair video quality is ensured.
- transmitting the multiplexed video signal through a broadcast channel;
- transmitting independently a status of fullness of each buffer in the central unit to each corresponding server for the next R-D control process.</p> |
