Abstract: An electronic device for decoding video data is provided. The electronic device includes a processor, and non-transitory computer-readable media coupled to the processor and storing computer-executable instructions. When the computer-executable instructions are executed by the processor, the computer-executable instructions cause the device to decode a first flag syntax in a picture parameter set (PPS); decode a second flag syntax in the PPS; decode a first number syntax when the first number syntax is present in the PPS; decode a slice address syntax when the slice address syntax is present in a slice header; determine, based on the value of the first flag syntax, whether a second number syntax is present in the slice header; and derive a variable specifying a number of the tiles within each of the at least one slice by using the second number syntax when the second number syntax is present in the slice header.

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 a purpose of a post-processing filter and a syntax element specifying whether syntax elements related to a purpose, input formatting, output formatting, and complexity of the post-processing filter are present in the neural network post-filter characteristics message. The syntax element indicating a purpose may precede the syntax element specifying whether syntax elements are present.

Abstract: A device may comprise one or more processors configured to: derive variables BitDepth Y and BitDepthC equal to BitDepth Y and BitDepthC; decode a slice QP SliceQPY and a offset QpBdOffsetY; derive StrengthControlVal equal to a value of (SliceQpY+QpBdOffsetY)÷(51+QpBdOffsetY) of a first slice of current coded picture; and set StrengthControlVal to an input tensor.

Abstract: A device may be configured to perform frame rate upsampling 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 specifying a number of input pictures to be used as input for a neural network post-filter picture interpolation process and a syntax element having a value specifying a manner in which input pictures are concatenated before being input into the neural network post-filter picture interpolation process.

Abstract: A method of decoding video data includes: receiving a picture parameter set; parsing a first syntax element specifying whether a rectangular slice mode is in use for each picture referring to the picture parameter set; conditionally parsing a second syntax element in a case that the rectangular slice mode is in use; conditionally parsing a third syntax element in a case that the rectangular slice mode is in use and that each subpicture consists of a set of one or more rectangular slices; conditionally parsing a fourth syntax element based on a value of the third syntax element being greater than a threshold value; and conditionally parsing one of index delta value syntax elements associated with an index value in a case that the index delta value syntax elements are present and the index value is less than the value of the third syntax element.

Abstract: A method of decoding video data includes receiving a first decoding unit information message corresponding to a first decoding unit of a current access unit, determining a syntax element used to compute a decoded picture buffer output time of the current access unit is not present in the first decoding unit information message, and based on the syntax element not being present in the first decoding unit information message, inferring the value of the syntax element to be equal to a value of a corresponding instance of the syntax element in a second decoding unit information message, wherein the second decoding unit information corresponds to a second decoding unit belonging to the current access unit.

Abstract: A device may be configured to generate data packets including a packet header and a payload. The packet header may include a value that signals whether the payload encapsulates input data according to a single short packet encapsulation, a single long packet encapsulation, a segmented encapsulation, or a concatenated encapsulation.

Abstract: This disclosure relates to video coding and more particularly to techniques for signaling subpicture information for coded video. In one example, a method of decoding video data comprises: receiving a general constraint information syntax elements; parsing a first syntax element from the general constraint information syntax elements specifying whether a constraint is imposed on the number of slices that being contained in each subpicture; receiving a picture parameter set syntax elements; and parsing a second syntax element from the picture parameter set syntax elements specifying that each sub-picture contains one and only one slice, wherein a value of the second syntax element is constrained according to the first syntax element parsed from the general constraint information syntax elements.
