Method and System Using Prediction and Error Correction for the Compact Representation of Quantization Matrices In Video Compression

摘要

In some implementations, a method for encoding data comprising a matrix of elements for scaling transform coefficients before quantization of the scaled transform coefficients includes generating a sequence of values from the elements of the matrix according to a predetermined order. A plurality of adjacent values in the sequence is generated from respective elements of the matrix. A representation of the data is encoded based at least in part on encoding repeated instances of a specified series of two or more values in the sequence as a corresponding symbol not appearing in the sequence.
