    摘要： Systems and methods for encoding a decoding video data are disclosed. The method for decoding video data can include receiving a bitstream having a plurality of layers of video data. The plurality of layers of video data can include a base layer and a video parameter set (VPS). The VPS can indicate a plurality of output layer sets (OLS) and profile, tier, and level (PTL) information for each OLS of the plurality of OLSs, including the 0th OLS. The method for decoding can also include selecting an OLS from the one or more layers as a target OLS, and decoding the target OLS based on PTL information signaled in the VPS.

    摘要： In an example, the disclosure provides for receiving a coded video sequence comprising encoded pictures of a video sequence and receiving timing parameters for the coded video sequence that include a time scale and a number of units in a clock tick at most once in a video parameter set (VPS) syntax structure referenced by the coded video sequence and at most once in a video usability information (VUI) part of a sequence parameter set (SPS) syntax structure referenced by the coded video sequence. Another example provides for encoding pictures of a video sequence to generate a coded video sequence and signaling timing parameters for the coded video sequence by at least in part signaling a time scale and a number of units in a clock tick at most once in a VPS syntax structure and at most once in a VUI part of a SPS syntax structure.

    摘要： A method of coding video data includes receiving video information associated with a first layer and a second layer and determining whether at least one of the first layer and the second layer is a default layer. The method can include at least partially restricting inter-layer prediction when neither the first layer nor the second layer is the default layer. A default layer can be a base layer or an enhancement layer. A flag can be received that indicates that inter-layer prediction is to be restricted. In addition, the method can include determining whether inter-layer prediction is allowed for the video information associated with the first layer, and determining whether inter-layer prediction is partially allowed for the video information associated with the second layer such that motion compensation is not used with the second layer video information.

    摘要： Techniques are described related to output and removal of decoded pictures from a decoded picture buffer (DPB). The example techniques may remove a decoded picture from the DPB prior to coding a current picture. For instance, the example techniques may remove the decoded picture if that decoded picture is not identified in the reference picture set of the current picture.

    摘要： This disclosure provides devices and methods for processing video data. The method can include extracting an output operation point from received video data. If the output operation point corresponds to one of an entire bitstream and a temporal subset of the entire bitstream with only the base layer as output, the method can include performing a first bitstream conformance test. If the output operation point corresponds to one of a layer set specified by a base video parameter set (VPS) of an active VPS and a temporal subset of the layer set with only the base layer to be output, the method can include performing a second bitstream conformance test. If the output operation point corresponds to one of an output layer set (OLS) specified by a VPS extension of the active VPS and a temporal subset of the OLS, the method can include performing a third bitstream conformance test.
