20210385467 | Methods and Apparatuses of Chroma Quantization Parameter Derivation in Video Processing System - Video data processing methods and apparatuses comprise receiving input data associated with a current chroma block, determine a luma Quantization Parameter (QP) of a collocated luma block, reuse the luma QP of the collocated luma block to derive a chroma QP for the current chroma block, and encode or decode one or more Transform Units (TUs) associated with the current chroma block using the chroma QP. The collocated luma block is a block that covers a collocated sample of one predefined sample of the current chroma block, and an example of the predefined sample is a center sample of the current chroma block. The input video data is partitioned according to two separate Coding Unit (CU) partitioning structures for luma and chroma components when dual tree coding is enabled. | 2021-12-09 |
20210385468 | METHODS, APPARATUSES, COMPUTER PROGRAMS AND COMPUTER-READABLE MEDIA FOR PROCESSING CONFIGURATION DATA - Configuration data is obtained and is useable by a decoder to reconstruct a first representation of an image at a first level of quality using a second representation of the image at the first level of quality. The second representation is based on a representation of the image at a second, lower level of quality. The configuration data comprises a value of a configuration parameter, the value having a variable bit-length. The configuration data is arranged into a sequence of bytes comprising a variable-length element arranged to store the value of the configuration parameter. The variable-length element comprises at least one given byte having one or more predetermined bits arranged to indicate whether or not the variable-length element comprises one or more additional bytes to the at least one given byte. The sequence of bytes is output for processing by the decoder. | 2021-12-09 |
