<p>Process for delivering a video stream over a wireless channel, wherein the video frames of the video stream are encoded by defining partitions of the video frames, said encoding being done by determining predictions for the partitions, a prediction being based on two reference areas (A1, A2) each of independent reference frames of the video stream; one motion vector associated to each reference area (A1, A2); and a weighting factor (W1, W2) for each motion vector; wherein the difference between partition and corresponding predicted partition is done in order to establish a partition residual, the encoded video stream with partition residuals are transmitted to a video decoder in order to decode predicted partition of the video stream by using the two reference areas (A1, A2), the motion vectors and weighting factor based on encoded weighting factor (W1, W2) balanced by a transmission error probability (PA1, PA2) computed for each reference area (A1, A2), decoded partition (M) of the video frame being formed by combination of decoded predicted partition and corresponding partition residual.</p> |
