Abstract: Techniques of this disclosure provide an indication of whether a parameter set update can occur in a portion of a bitstream. The indication may enable a video decoder to determine whether an update of a stored parameter set can occur without performing a content comparison between the stored parameter set and a new parameter set of the same type with the same identification value. A parameter set update includes storing a current parameter set with a given identification value to replace a previous parameter set of the same type and having the same identification value. When a parameter set update cannot occur, the video decoder may store and activate a single parameter set of a given type for the entire portion of the bitstream. When a parameter set update can occur, the video decoder may automatically update a stored parameter set, or may determine whether to update the stored parameter.

Abstract translation: 本公开的技术提供了参数集更新是否可以在比特流的一部分中发生的指示。 该指示可以使得视频解码器可以确定是否可以发生存储的参数集的更新，而不执行存储的参数集与具有相同标识值的相同类型的新参数集之间的内容比较。 参数集更新包括存储具有给定标识值的当前参数集以替换相同类型的并且具有相同标识值的先前参数集。 当不能发生参数集更新时，视频解码器可存储和激活比特流的整个部分的给定类型的单个参数集。 当可能发生参数集更新时，视频解码器可以自动更新存储的参数集，或者可以确定是否更新所存储的参数。

Abstract: Systems, methods, and devices for processing video data are disclosed. Some examples receive a slice of a current picture to be decoded for a sequence of video data. These examples may also receive, in a slice header of the slice, at least one entropy coded syntax element and at least one non-entropy coded syntax element, wherein the non-entropy coded syntax element is before the entropy coded syntax element in the slice header and indicates whether pictures prior to the current picture in decoding order are to be emptied from a decode picture buffer without being output. They may decode the slice based on the non-entropy coded syntax element.

Abstract: Systems, methods, and devices for processing video data are disclosed. Some examples determine that a current picture is a broken-link access (BLA) picture. These examples may also mark a reference picture in a picture storage buffer as unused for reference. In some examples, this may be done prior to decoding the BLA picture.

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: As one example, a method of coding video data includes storing one or more decoding units of video data in a coded picture buffer (CPB). The method further includes obtaining a respective buffer removal time for the one or more decoding units. The method further includes removing the decoding units from the CPB in accordance with the obtained buffer removal time for each of the decoding units. The method further includes determining whether the CPB operates at access unit level or sub-picture level. The method further includes coding video data corresponding to the removed decoding units. If the CPB operates at access unit level, coding the video data comprises coding access units comprised in the decoding units. If the CPB operates at sub-picture level, coding the video data comprises coding subsets of access units comprised in the decoding units.

Abstract: In one example, a device includes a video coder (e.g., a video encoder or a video decoder) configured to determine that a block of video data is to be coded in accordance with a three-dimensional extension of High Efficiency Video Coding (HEVC), and, based the determination that the block is to be coded in accordance with the three-dimensional extension of HEVC, disable temporal motion vector prediction for coding the block. The video coder may be further configured to, when the block comprises a bi-predicted block (B-block), determine that the B-block refers to a predetermined pair of pictures in a first reference picture list and a second reference picture list, and, based on the determination that the B-block refers to the predetermined pair, equally weight contributions from the pair of pictures when calculating a predictive block for the block.
