摘要： A video data stream is rendered reducible in a manner so that the reduction leads to a restriction of pictures of the reduced video data stream to merely a predetermined subarea of the pictures of the original video data stream and in a manner so that transcoding, such as re-quantization, may be avoided and a conformance of the reduced video data stream relative to the codec underlying the original video data stream be maintained. This is achieved by providing the video data stream with information including an indication of the predetermined subarea and replacement indices for redirecting the indices included by the payload portion so as to refer to, and/or replacement parameters for adjusting the first set of coding parameter settings so as to result in, a second set of coding parameter settings.

摘要： Implementations of the disclosure provide a video processing method for invertible filtering in video coding. The video processing method may include receiving, by a processor, an image derived from encoded video information stored in a bitstream. The video processing method may also include applying, by the processor, a forward filter to the image to generate an intermediate image and flipping the intermediate image. The video processing method may further include applying, by the processor, an inverse filter to the flipped intermediate image to generate a reconstructed image, and inversely flipping the reconstructed image to generate an invertible reconstructed image.

摘要： Method, device, and non-transitory storage medium for interleaved motion vector prediction (MVP) for video coding are provided. A MVP candidate list for a current block may be generated based on spatial motion vectors associated with neighboring blocks and non-neighboring blocks. A first spatial motion vector predictor (SMVP) associated with an adjacent neighboring block to the left of the current block may be inserted into the MVP candidate list, and a second SMVP associated with an adjacent neighboring block to the top of the current block may be inserted into the MVP candidate list. One or more candidates in the MVP candidate list may be pruned based on determining that the one or more candidates have a same SMVP.

摘要： Disclosed herein are innovations for bitstreams having clean random access (CRA) pictures and/or other types of random access point (RAP) pictures. New type definitions and strategic constraints on types of RAP pictures can simplify mapping of units of elementary video stream data to a container format. Such innovations can help improve the ability for video coding systems to more flexibly perform adaptive video delivery, production editing, commercial insertion, and the like.

摘要： Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: obtaining, during a conversion between a target block of a video and a bitstream of the video, a list of adaptive decoder side motion vector refinement (ADMVR) merge candidates for the target block in an ADMVR merge mode; reordering the list of ADMVR merge candidates; and performing the conversion based on the reordered list of ADMVR merge candidates. Compared with the conventional solution, the proposed method can advantageously improve the coding effectiveness and coding efficiency.

摘要： An image decoding method according to the present invention can comprise the steps of: acquiring residual coefficients of a current block; dequantizing the residual coefficients; performing secondary inverse transformation on the dequantized residual coefficients; and performing primary inverse transformation on the performance result of the secondary inverse transformation. The secondary inverse transformation can be performed for a partial region of the current block.
