Abstract: Systems and methods for performing motion vector prediction for video coding are disclosed. A motion vector predictor is determined based at least in part on motion information associated with a selected motion vector predictor origin and offset values corresponding to a selected sampling point. The sampling point is specified according to a set of direction and distance on a sampling map for the motion vector predictor origin.

Abstract: A device may be configured to perform filtering based on information included in a neural network post-filter characteristics message. In one example, the neural network post-filter characteristics message includes a syntax element indicating auxiliary input data is present in an input tensor of the neural network post-filter. The device may derive a filtering strength control value array where each entry in the array is based on a quantization parameter of a respective input picture for the neural network post-filter.

Abstract: A device may be configured to perform filtering based on information included in a neural network post-filter characteristics message. In one example, the neural network post-filter characteristics message includes a syntax element indicating matrices which are present for an input tensor of a neural network post-filter. In one example, the neural network post-filter characteristics message conditionally includes a syntax element indicating a bit depth of chroma sample values, in cases where chroma matrices are present.

Abstract: A method of filtering reconstructed video data is disclosed. The method comprising: parsing a first syntax element used for setting cross-component filter coefficients; inputting a reconstructed luma picture sample array; deriving luma locations by using location corresponding to a current chroma sample; deriving a filter coefficient array by using the cross-component filter coefficients; deriving a variable by using the filter coefficient array and the reconstructed luma picture sample array defined by the luma locations; and deriving a scaled variable by using the variable, wherein the variable is modified by a sum of a sample of a current chroma block, which is defined by a predetermined location, and the scaled variable.

Abstract: A device may be configured to signal neural network post-filter parameter information. In one example, a device signals a neural network post-filter characteristics message including a syntax element specifying a number of interpolated pictures generated by a post-processing filter between consecutive pictures used as input for the post-processing filter. In one example, a neural network post-filter characteristics message includes a syntax element specifying a number of decoded output pictures used as input for the post-processing filter.

Abstract: This disclosure relates to video coding and more particularly to techniques for signaling picture timing and decoding unit information for coded video. According to an aspect of an invention, a flag syntax element, specifying whether decoding unit level decoded picture buffer output delay parameters are present in a picture timing message, in a buffering period message is parsed and a first syntax element, used to compute a decoded picture buffer output time, in the picture timing message is parsed, in a case that a value of the flag syntax element is equal to one.
