摘要： Disclosed is a video encoding and decoding technology using a differential modulation technique for a residual signal in order to enhance compression performance in a transform skip mode. The differential modulation technique is applicable to both luma and chroma components as long as the chroma format is not monochrome (i.e. as long as chroma_format_idc=0 is not true).

摘要： A method and a device for inversely transforming transform coefficients of a current block are disclosed. A method for predicting a current block according to a first mode includes the steps of: on the basis of a partition mode syntax element, partitioning the current block into non-rectangular blocks; determining an intra-predicted intra block and an inter-predicted inter block among the non-rectangular blocks; and deriving prediction samples of a first area including the inter block on the basis of motion information, and deriving prediction samples of a second area including the intra block on the basis of an intra prediction mode.

摘要： Disclosed are a method and an apparatus for intra prediction coding of video data. According to one aspect of the present disclosure, 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： Disclosed is a method for decoding a current block in a current picture included in a high-level layer performed based on a reference picture included in a low-level layer and having a different resolution. A prediction mode for the current block, a decoded residual signal, and decoding information for the current block, are obtained. When the prediction mode is the inter-prediction, a prediction signal for the current block is generated based on the decoding information. A reconstructed block is then generated by adding the prediction signal to the residual signal. Filtering is then performed for correcting the different resolution that is applied to a reference block included in the reference picture such that the different resolution matches a resolution of the current block.
