摘要： There is provided a method of encoding a video signal, the method comprising: receiving an input frame; processing the input frame to generate at least one set of residuals data, the residuals data enabling a decoder to reconstruct the input frame from a reference reconstructed frame; and, applying a run-length coding operation to the set of residuals data, wherein the run-length coding operation comprises generating a run-length encoded bytestream comprising a set of symbols representing non-zero data values of the residuals data set and counts of consecutive zero values of the residuals data set. In certain embodiments the method comprises apply a Huffman coding operation to the set of symbols. A method of decoding is also provided as well as apparatuses and a computer readable medium.

摘要： Computer processor hardware: parses a data stream into first portions of encoded data and second portions of encoded data; implements a first decoder to decode the first portions of encoded data into a first rendition of a signal; implements a second decoder to decode the second portions of encoded data into reconstruction data, the reconstruction data specifying how to modify the first rendition of the signal; and applies the reconstruction data to the first rendition of the signal to produce a second rendition of the signal.

摘要： Computer processor hardware receives a first set of adjustment values. The first set of adjustment values specify adjustments to be made to a predicted rendition of a signal generated at a first level of quality to reconstruct a rendition of the signal at the first level of quality. The computer processor hardware processes the first set of adjustment values and derives a second set of adjustment values based on the first set of adjustment values and a rendition of the signal at a second level of quality. The second level of quality is lower than the first level of quality.
