PROCESS FOR DELIVERING A VIDEO STREAM OVER A WIRELESS BIDIRECTIONAL CHANNEL BETWEEN A VIDEO ENCODER AND A VIDEO DECODER

A process for delivering a video stream over a bidirectional wireless channel between a video encoder and a video decoder, is provided. The video frames of the video stream are encoded by determining predictions for defined partitions of the video frames, a prediction being based on at least one reference area of a reference frame of the video stream; one motion vector associated to said reference area; and a weighting factor associated to said reference area. The difference between partition and corresponding predicted partition is done to establish a partition residual, the encoded video stream with partition residual are transmitted to the video decoder to decode predicted partition, decoded partition of the video frame being formed by combination of decoded predicted partition and corresponding partition residual. A transmission error probability of the decoded partition is fed back to the video encoder.
