摘要： In an information processing apparatus, a GPU obtains a plurality of blocks which have a predetermined number of pixels and are obtained by dividing an encoding target image, and intermediate blocks for which a spatial redundancy is removed are generated for each block. The GPU analyzes a data string of the intermediate blocks, and generates specifying information for specifying positions of data for which a value is included in a predetermined range in the data string, and for each of the blocks, outputs at least a portion of the data of the intermediate blocks, and corresponding specifying information to a storage apparatus. A CPU, for each of the plurality of blocks, executes compression processing by referencing corresponding specifying information, and reading at least a portion of the data corresponding to the specifying information from the storage apparatus.

摘要： A system is provided for creating level parameter updating codewords for transform coefficients used for relating transform units (TUs) that divide up coding units (CUs) in a High Efficiency Video Coding (HEVC) system. The system provides binarization of the codewords and removes unnecessary operations to reduce system complexity and increase compression performance. The system generates transform coefficients that relate the TUs and begins by providing a parameter variable (cRiceParam) set to an initial value of zero. The parameter variable is then converted into a binary codeword based on the current value of the parameter variable and the value of a symbol and then updated with a new current value after each symbol has been converted. Updating can be provided with reference to table values or the values can be provided from combination logic.

摘要： A method and an apparatus for encoding and decoding transform coefficients are disclosed. The encoding method includes: encoding transform coefficients of a transform coefficient block according to a predetermined scan order, and encoding a set number of transform coefficients in each group until a last group of the transform coefficient block is encoded; storing an obtained map of non-zero transform coefficients, absolute values of transform coefficients, and positive and negative signs of non-zero transform coefficients; when the last group is being encoded, after obtaining a map of non-zero transform coefficients encoded in the last group, encoding the stored map of non-zero transform coefficients and the map of non-zero transform coefficients encoded in the last group into a bit stream; and after obtaining absolute values of transform coefficients and positive and negative signs of non-zero transform coefficients encoded in the last group, encoding the stored absolute values of transform coefficients and positive and negative signs of non-zero transform coefficients and the absolute values of transform coefficients and positive and negative signs of non-zero transform coefficients encoded in the last group into the bit stream. Encoding and decoding efficiency can be increased.
