Abstract: An apparatus configured to code video information includes a memory unit and a processor in communication with the memory unit. The memory unit is configured to store video information associated with a reference layer (RL) and an enhancement layer, the RL comprising an RL picture having an output region that includes a portion of the RL picture. The processor is configured to determine whether a condition indicates that information outside of the output region is available to predict a current block in the enhancement layer. The processor may encode or decode the video information.

Abstract: During a coding process, systems, methods, and apparatus may code information indicating whether gradual decoder refresh (GDR) of a picture is enabled. When GDR is enabled, the coding process, systems, methods, and apparatus may code information that indicates whether one or more slices of the picture belong to a foreground region of the picture. In another example, during a coding process, systems, methods, and apparatus may decode video data corresponding to an ISP identification (ISP ID) for one of the ISPs for slices of a picture. The systems, methods, and apparatus may decode video data corresponding to an ROI using the ISP.

Abstract: This disclosure describes techniques that may enable a video coder to simultaneously implement multiple parallel processing mechanisms, including two or more of wavefront parallel processing (WPP), tiles, and entropy slices. This disclosure describes signaling techniques that are compatible both with coding standards that only allow one parallel processing mechanism to be implemented at a time, but that are also compatible with potential future coding standards that may allow for more than one parallel processing mechanism to be implemented simultaneously. This disclosure also describes restrictions that may enable WPP and tiles to be implemented simultaneously.

Abstract: Techniques of this disclosure provide an indication of whether performing random access from a particular access unit in a bitstream requires fetching of parameter sets from previous access units. A clean random access (CRA) picture can be positioned at any point within a coded video sequence and does not clean a decoded picture buffer (DPB) of a video decoder. In order to perform random access decoding from the CRA picture, a video decoder may need to fetch one or more parameter sets included in unavailable access units that precede the CRA picture. The techniques provide an indication, for each CRA picture, that indicates whether parameter sets included in previous access units are needed to perform random access from the picture. When no parameter sets from previous access units are needed for random access from a particular CRA picture, a video decoder may determine to perform random access from that picture.

Abstract translation: 本公开的技术提供了是否从比特流中的特定接入单元执行随机接入的指示需要从先前接入单元获取参数集。 干净的随机访问（CRA）图像可以被定位在编码视频序列内的任何点处，并且不清除视频解码器的解码图像缓冲器（DPB）。 为了从CRA图像执行随机访问解码，视频解码器可能需要获取包括在CRA图像之前的不可用访问单元中的一个或多个参数集。 这些技术为每个CRA图片提供指示是否需要包括在先前访问单元中的参数集来执行从图像的随机访问的指示。 当不需要来自先前存取单元的参数组用于从特定CRA图像进行随机存取时，视频解码器可以确定从该图像执行随机存取。

Abstract: In one example, a device for decoding video data includes a video decoder configured to decode one or more syntax elements of a current reference picture set (RPS) prediction data structure, wherein at least one of the syntax elements represents a picture order count (POC) difference between a POC value associated with the current RPS and a POC value associated with a previously decoded RPS, form a current RPS based at least in part on the RPS prediction data structure and the previously decoded RPS, and decode one or more pictures using the current RPS. A video encoder may be configured to perform a substantially similar process during video encoding.

Abstract: An apparatus for coding video information according to certain aspects includes a memory unit configured to store video information associated with a plurality of layers and a processor. The processor is configured to obtain information associated with a current access unit (AU) to be coded, the current AU containing pictures from one or more layers of the plurality of layers. The processor is also configured to reset a picture order count (POC) of a layer included in the current AU via (1) resetting only a most significant bit (MSB) of the POC or (2) resetting both the MSB of the POC and a least significant (LSB) of the POC. The processor is further configured to, for pictures in one or more Ails subsequent to the current AU in decoding order: set a value of a first flag indicative whether a reset of the POC is a full reset.
