Abstract: Encoding and/or decoding a block of a video frame may be based on a previously decoded reference block in the same frame or in a different frame. The reference block may be indicated by a block vector (BV). The BV may be encoded as difference between a block vector predictor (BVP) and the BV. The BVP may be adjusted to improve prediction accuracy of the BVP.

Abstract: A decoder may generate a reconstruction of a luma block based on a prediction of the luma block and a residual of the luma block. The decoder may generate, at one or more hidden layers, a score distribution. The decoder may generate the score distribution based on the reconstruction of the luma block and one or more coding parameters of the luma block. The decoder may generate, at an output layer and based on the score distribution, a prediction of a chroma block corresponding to the luma block. The decoder may determine a reconstruction of the chroma block based on the prediction of the chroma block and a residual of the chroma block.

Abstract: A decoder determines, in a reference region having dimensions based on dimensions of a current block, a location of a first reference block (RB) based on a template of the current block and a template of the first RB. The decoder receives an indication of a block vector difference (BVD) from a bitstream. The decoder decodes the current block based on a second RB at a location that is displaced from the location of the first RB by the BVD.

Abstract: An apparatus receives, in a bitstream for a block, an indication of a block vector predictor (BVP) and a first and a second component magnitude of a block vector difference (BVD). The apparatus determines each of a plurality of block vector (BV) candidates based on a sum of the BVP and a different one of a plurality of BVD candidates. Each of the plurality of BVD candidates includes: the first and second component magnitudes of the BVD, and a different combination of signs for the first and second component magnitudes. Validities of the plurality of BV candidates are determined based on values of samples, stored in a reference memory, of reference blocks indicated by the plurality of BV candidates. The apparatus determines a sign for at least one of the first and second component magnitudes of the BVD based on the validities of the plurality of BV candidates.

Abstract: An apparatus calculates a block vector difference (BVD) between a block vector (BV) and a block vector predictor (BVP). The apparatus determines each of a plurality of BV candidates based on a sum of the BVP and a different one of a plurality of BVD candidates. Each of the plurality of BVD candidates comprises: a first and a second component magnitude of the BVD; and a different combination of signs for the first and second component magnitudes. The apparatus determines validities of the plurality of BV candidates based on values of samples, stored in a reference memory, of reference blocks indicated by the plurality of BV candidates. The apparatus signales, in a bitstream, a sign for at least one of the first and second component magnitudes of the BVD based on the validities of the plurality of BV candidates.

Abstract: A flipping or non-flipping type of each BVP candidate in a candidate list may require correct classification/identification, for example, for correct reordering and accurate refinement A block vector predictor (BVP) candidate list may be adjusted to provide a more accurate prediction of a block vector (BV). A coder (e.g., encoder or decoder) may determine a final candidate list, for example, by pruning invalid candidates.

Abstract: A coder determines, based on a position of a block relative to a boundary and a property of the block, a first reference line offset and a second reference line offset that are different. The coder determines samples of a reference line based on the first reference line offset and the second reference line offset. The coder predicts the block based on the samples of the reference line and an intra prediction mode.

Abstract: A coder determines, based on a reference line index and at least a width or a height of a block, a horizontal reference line offset and a vertical reference line offset, where the horizontal reference line offset and the vertical reference line offset are different. The coder determines a reference line based on the horizontal reference line offset and the vertical reference line offset. The block is predicted based on the reference line and an intra prediction mode.

Abstract: An optimal reconstructed-reordered template matching prediction (RRTMP) flipped mode is determined for a reference block. The reference block may be flipped, or not, based on the RRTMP flip mode. At least one horizontal or vertical transform, associated with the reference block, is selected for coding a residual block (e.g., a difference between the reference block and a current block).

Abstract: A wireless device receives, from an SMF, a message for a PDU session establishment, wherein the message comprises a configuration information for determining whether one or more packets are associated with a plurality of packets of a data unit (DU) based on a timestamp field of the one or more packets. The wireless device determines, based on the configuration information, that a first packet, comprising a first timestamp field, is one of a first plurality of packets of a first DU, and a second packet, comprising a second timestamp field, is one of the first plurality of packets of the first DU. The wireless device sends, to a base station, the first packet and the second packet.

Abstract: A decoder receives, from a bitstream, an indication of a block vector predictor (BVP) and a first block vector difference (BVD) for a current block. The decoder determines a second BVD based on: the first BVD and whether a location displaced from the current block by a sum of the BVP and the first BVD is outside a reference region. The decoder calculates a block vector (BV) based on a sum of the second BVD and the BVP. The decoder reconstructs the current block based on a reference block indicated by the BV.

Abstract: A user plane function UPF receives, from a SMF, a DU identification information for identifying a plurality of packets for one or more DUs of an application. The UPF receives a first plurality of packets, of the plurality of packets, of a first DU of the application; and a second plurality of packets, of the plurality of packets, of a second DU of the application. The UPF sends, to an access node and using the DU identification information a first GTP container comprising a first GTP header comprising a first number identifying the first plurality of packets, and a second GTP container comprising a second GTP header comprising a second number identifying the second plurality of packets.

Abstract: Encoding and/or decoding a block of a video frame may be based on a previously decoded reference block in the same frame or in a different frame. The reference block may be indicated by a block vector (BV). The BV may be encoded as difference (e.g., block vector difference (BVD)) between a block vector predictor (BVP) and the BV. The BVP may comprise a null component, for example, based on the BV comprising a null component. Signaling overhead may be reduced by indicating whether the BV comprises a null component and/or a direction of the null component.

Abstract: A decoder receives, from a bitstream, a first indication of a first bit depth for a sequence of frames, and a second indication of a second bit depth for a block in a frame of the sequence of frames, a residual block of samples of the second bit depth, and a prediction parameter. The decoder determines a first decoded block of samples of the second bit depth based on the second bit depth indicated by the second indication, the residual block of samples, and the prediction parameter. The decoder converts, based on a difference between the first bit depth and the second bit depth, the first decoded block of samples to a second decoded block of samples of the first bit depth based on the first decoded block of samples of the second bit depth and the first indication of the first bit depth for the sequence.

The BVP may be selected based on a distance between the BVP and another BVP which may improve diversity of selected BVPs and improve prediction accuracy of the BVP.
