Abstract: 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.

Abstract: A method of transmitting data packets over an air interface is disclosed. At least a first and second stream of data packets are multiplexed, wherein a multiplexed stream of data packets is generated. The multiplexed stream of data packets is processed by a forward error correction function, wherein the forward error correction function adds redundancy bits to the multiplexed stream of data packets, wherein a third stream of data packets is generated, and wherein the redundancy bits are used for an error control to be performed on the third stream of data packets. The third stream of data packets is then transmitted over the air interface.
