Abstract: An encoding system comprises: an input for receiving a video signal comprising a plurality of frames each comprising a plurality of higher resolution samples; and a projection generator configured, for each respective one of the frames, to generate multiple different projections of the respective frame. Each projection comprises a plurality of lower resolution samples representing the respective frame at a lower resolution, wherein the lower resolution samples of the different projections represent different but overlapping groups of the higher resolution samples of the respective frame. The encoding system comprises an encoder configured to encode the video signal by encoding the projections of each of the respective frames.

Abstract: Correction data units for data packets of a data stream are generated. A correction data unit is based on a set of the data packets of the stream. The stream is transmitted over a lossy communication channel. A performance measure to be optimized is selected, which relates to the recovery of lost data packets of the stream. A coding requirement is determined. For the generation of the correction data units, it is determined, within the constraints of the coding requirement and based on previously generated correction data units, which of the data packets in the stream to include in the set on which the generation of the correction data unit is to be based to thereby optimize the selected performance measure. A generated correction data unit is generated based on a respective set of the data packets of the stream. The generated correction data units are included in the stream.
