    摘要: The present invention relates to the field of coding and decoding technologies, and discloses video data coding and decoding methods and apparatuses, which can improve coding efficiency or is low in transmission flexibility. The decoding method provided by the present invention includes: determining a first to-be-decoded information group in a to-be-decoded bitstream, where the first to-be-decoded information group includes data information, attribute information, and location information of the first to-be-decoded information group; determining a reference information group set in a case in which the attribute information represents that the first to-be-decoded information group is a redundant information group; and discarding the first to-be-decoded information group if location information of at least one reference information group in the reference information group set is the same as the location information of the first to-be-decoded information group, or parsing the data information if location information of all reference information groups in the reference information group set is different from the location information of the first to-be-decoded information group.

    摘要: Systems and methods for improved intra prediction in video coding. The disclosure provides an intra prediction scheme that not only uses pixels in neighboring blocks as external reference pixels but also uses pixels within a current block as internal reference pixels. Block residuals thus obtained may be lossy or lossless encoded.

    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.
