Abstract: In one example, a video coder may be configured to determine that a slice of a picture of video data begins in a row of coding tree units (CTUs) in the picture at a position other than a beginning of the row. Based on the determination, the video coder may be further configured to determine that the slice ends within the row of CTUs. The video coder may be further configured to code the slice based on the determination that the slice ends within the row of CTUs.

Abstract: A video encoder signals whether WPP is used to encode a picture of a sequence of video picture. If WPP is used to encode the picture, the video encoder generates a coded slice NAL unit that includes a plurality of sub-streams, each of which includes a consecutive series of bits that represents one encoded row of coding tree blocks (CTBs) in a slice of the picture. A video decoder receives a bitstream that includes the coded slice NAL unit. Furthermore, the video decoder may determine, based on a syntax element in the bitstream, that the slice is encoded using WPP and may decode the slice using WPP.

Abstract: Techniques described herein for coding video data include techniques for coding pictures partitioned into tiles, in which each of the plurality of tiles in a picture is assigned to one of a plurality of tile groups. One example method for coding video data comprising a picture that is partitioned into a plurality tiles comprises coding video data in a bitstream, and coding, in the bitstream, information that indicates one of a plurality of tile groups to which each of the plurality of tiles is assigned. The techniques for grouping tiles described herein may facilitate improved parallel processing for both encoding and decoding of video bitstreams, improved error resilience, and more flexible region of interest (ROI) coding.

Abstract: A computing device, such as a video encoder, determines an initial quantized level for a coefficient of a coefficient block and determines whether the coefficient is less than the product of the initial quantized level and a quantization step size value. In response to determining that the coefficient is less than the product of the initial quantized level and the quantization step size value, the computing device determines rate-distortion costs of quantizing the coefficient to be the initial quantized level for the coefficient, the initial quantized level minus one, and in some circumstances, 0. The computing device determines an actual quantized level for the coefficient based at least in part on the calculated rate-distortion costs and includes the actual quantized level in a quantized version of the coefficient block.

Abstract: In an example, a method of processing data includes determining, by a receiver device, an allowable excess delay parameter based on a difference between a time at which received data is received by the receiver device and a time at which the received data is scheduled to be played out, where the allowable excess delay parameter indicates an amount of delay that is supportable by a channel between a sender device and the receiver device. The method also includes determining, by the receiver device, a sender bit rate increase for increasing a bit rate at which data is to be sent from the sender device to the receiver device based on the determined allowable excess delay parameter, and transmitting an indication of the sender bit rate increase to the sender device.
