    摘要： A decoder configured to receive a first output video and one or more further encoded streams, decode respective frames of the one or more further encoded streams to derive respective sets of residuals; and combine the sets of residuals with the first output video to generate a reconstructed output video. Each frame is divided into a plurality of tiles and each tile is divided into a plurality of blocks. To decode respective frames, the decoder is configured to obtain a preliminary set of residuals from the one or more further encoded streams, derive a set of temporal predictions using a temporal buffer, and combine the set of temporal predictions with the preliminary set of residuals. The decoder is configured to provide for zeroing of values of the set of temporal predictions at a frame level, at a tile level and at a block level.

    摘要： A method of processing image data, the method comprising:obtaining a representation of an image at a first level of quality;obtaining reconstruction data useable to reconstruct a representation of the image at a second, higher level of quality using the representation at the first level of quality;arranging the representation at the first level of quality and data useable to derive the reconstruction data into a compressed data stream; and out putting the compressed data stream for processing by a device to enable the device to reconstruct the representation at the second level of quality.
