    Abstract: A method of decoding is provided. The method includes receiving a video bitstream including a picture unit (PU), where any decoding capability information (DCI) network abstraction layer (NAL) unit, video parameter set (VPS) NAL unit, sequence parameter set (SPS) NAL unit, or picture parameter set (PPS) NAL unit referred to by the PU precedes a picture header (PH) NAL unit of the PU and a first video coding layer (VCL) NAL unit of the PU; and decoding a coded picture from the PU to obtain a decoded picture.

    Abstract: A method of decoding is provided. The method includes receiving a video bitstream including a picture unit (PU), the PU including a picture header (PH) network abstraction layer (NAL) unit having a picture header NAL unit type (PH_NUT) and an associated video coding layer (VCL) NAL unit, the PH_NUT signifying that a layer identifier (ID) of the PH NAL unit is equal to a layer ID of the associated video coding layer (VCL) NAL unit and a temporal ID of the PH NAL unit is equal to a temporal ID of the PU; and decoding a coded picture from the PU to obtain a decoded picture.

    Abstract: The disclosure relates to an apparatus and method for inter prediction of a sample value of a current full-integer pixel of a plurality of pixels of a current block of a current frame of a video signal. The apparatus comprises a processing unit configured to: determine a motion vector of the current full-integer pixel on the basis of the current frame and a reference frame of the video signal and/or on the basis of a motion compensation model; determine for the current full-integer pixel a corresponding sub-integer pixel in the reference frame on the basis of the motion vector of the current full-integer pixel; generate on the basis of a predefined set of filter support pixels in the current frame a set of corresponding filter support pixels in the reference frame, wherein the predefined set of filter support pixels in the current frame comprises one or more neighboring full-integer and/or sub-integer pixels of the current full-integer pixel; determine a respective sample value of the corresponding sub-integer pixel of the current full-integer pixel and the corresponding filter support pixels in the reference frame; and determine the inter predicted sample value of the current pixel in the current frame by applying a spatial high-pass filter to the sample value of the corresponding sub-integer pixel of the current full-integer pixel in the reference frame and to the sample values of the corresponding filter support pixels in the reference frame.

    Abstract: An apparatus and method for marking availability of a candidate coding block for merge estimation of a current coding block within a coding tree unit (CTU). The candidate block may be marked as unavailable if a splitting depth of the current coding block is equal to or larger than a predetermined threshold and a first location of the candidate block and a second location of the current block are included in a same merge estimation region (MER). Otherwise, the candidate block is marked as available. A candidate block may be marked as unavailable also, when a parent block “parentCurr” of the current block and a parent block “parentCand” of the candidate block, with both parent blocks obtained by splitting, are the same block and when the size of the parentCand is smaller than a threshold.

    Abstract: A video coding mechanism is disclosed. The mechanism includes encoding a sequence of point cloud compression (PCC) components into a bitstream. A buffering period supplemental enhancement information (SEI) message is also encoded into the bitstream. A hypothetical reference decoder (HRD) is initialized at a coded atlas access unit (AU) associated with the buffering period SEI message. A HRD conformance check of the bitstream is performed starting at the coded atlas AU. The bitstream is stored for communication toward a decoder.
