  • Publication number: 20220417552
    Abstract: 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.

  • Publication number: 20220417507
    Abstract: Disclosed herein are a video processing method, apparatus and storage medium using the resolution of a reference picture. Filtering is performed based on resolutions of reference pictures of blocks forming a boundary. The resolutions of the reference pictures may define filtering. Depending on whether the resolutions of the reference pictures are different from each other, one or more filter selection parameters for filtering may be determined or updated. Further, based on whether the resolutions of the reference pictures are different from each other, the boundary strength of the filter may be determined. Because filtering is defined using the resolutions of reference pictures, performance of encoding and/or decoding may be improved.
