摘要： A method and an apparatus are configured for intra prediction coding of video data. An apparatus for decoding video data includes: a decoding unit which obtains, from a bitstream, information on a luma prediction mode and information on a chroma prediction mode of a current coding block; and an intra prediction unit which generates luma prediction samples and chroma prediction samples of the current coding block. The intra prediction unit derives a luma intra prediction type and a luma intra prediction mode of the current coding block on the basis of the information on the luma prediction mode, and determines a chroma intra prediction mode of the current coding block on the basis of the luma intra prediction type and the luma intra prediction mode of the current coding block, and the information on the chroma prediction mode.

摘要： A method and an apparatus for parallel encoding and decoding of moving picture data are provided. The method includes decoding, from a bitstream, a syntax element indicating that a picture can be decoded using wavefront parallel processing and decoding encoded data of the picture. The step of decoding encoded data of the picture includes for a first coding block of a current CTU row encoded in a palette mode, predicting a palette table for the first coding block by using palette data from a first CTU of a previous CTU row and decoding the first coding block in the palette mode using the palette table predicted for the first coding block.

摘要： A video decoding apparatus is provided for decoding a sequence of pictures, some of which have different resolutions. The apparatus decodes, from a high-level syntax structure of the sequence, a first syntax element for specifying a reference size of pictures referring to the high-level syntax structure and a second syntax element for specifying a picture size scaled from the reference size of the picture referring to the high-level syntax structure. The apparatus predicts a current block, by modifying a sample position in a reference picture indicated by a motion vector of the current block based on the first and second syntax elements.
