Abstract: Bitstream restrictions or constraints on the partitioning of pictures across layers of video data are described. In some examples, the number of tiles per picture for each layer of a plurality of layers is constrained based on a maximum number of tiles per picture for the layer. In some examples, the number of tiles per picture for each layer of the plurality of layers is no greater than the maximum number of tiles per picture for the layer. In some examples, a sum of the numbers of tiles per picture for the plurality of layers is no greater than a sum of the maximum numbers of tiles per picture for the plurality of layers. In some examples, a second largest coding unit (LCU) or coding tree block (CTB) size for a second layer is constrained based on, e.g., to be equal to, a first LCU size for a first layer.

Abstract: This disclosure describes techniques for signaling deblocking filter parameters for a current slice of video data with reduced bitstream overhead. Deblocking filter parameters may be coded in one or more of a picture layer parameter set and a slice header. The techniques reduce a number of bits used to signal the deblocking filter parameters by coding a first syntax element that indicates whether deblocking filter parameters are present in both the picture layer parameter set and the slice header, and only coding a second syntax element in the slice header when both sets of deblocking filter parameters are present. Coding the second syntax element is eliminated when deblocking filter parameters are present in only one of the picture layer parameter set or the slice header. The second syntax element indicates which set of deblocking filter parameters to use to define a deblocking filter applied to a current slice.

Abstract: A method for processing video data in a real-time transport protocol (RTP) payload includes encapsulating video data in a single network abstraction layer (NAL) unit packet for an RTP session. The single NAL unit packet contains a single NAL unit. The method may also include encapsulating decoding order number information in the single NAL unit packet based on at least one of: the RTP session being in a multi-stream transmission (MST) mode, or a maximum number of NAL units that may precede the NAL unit in a de-packetization buffer in reception order and follow the NAL unit in decoding order being greater than 0.

Abstract: A video encoder is configured to determine a picture size for one or more pictures included in a video sequence. The picture size associated with the video sequence may be a multiple of an aligned coding unit size for the video sequence. In one example, the aligned coding unit size for the video sequence may comprise a minimum coding unit size where the minimum coding unit size is selected from a plurality of smallest coding unit sizes corresponding to different pictures in the video sequence. A video decoder is configured to obtain syntax elements to determine the picture size and the aligned coding unit size for the video sequence. The video decoder decodes the pictures included in the video sequence with the picture size, and stores the decoded pictures in a decoded picture buffer.
