    Abstract: A video encoder may generate a bitstream that includes a syntax element that indicates whether inter-layer prediction is enabled for decoding a tile of a picture of the video data. Similarly, a video decoder may obtain, from a bitstream, a syntax element that indicates whether inter-layer prediction is enabled. The video decoder may determine, based on the syntax element, whether inter-layer prediction is enabled for decoding a tile of a picture of the video data, and decode the tile based on the determination.

    Abstract translation: 视频编码器可以生成包括语法元素的比特流，该语法元素指示是否启用层间预测以对视频数据的图片的瓦片进行解码。 类似地，视频解码器可以从比特流获得指示是否启用层间预测的语法元素。 视频解码器可以基于语法元素确定层间预测是否能够用于解码视频数据的图像的图块，并且基于该确定来解码图块。

    Abstract: A method of coding video data includes receiving one or more layers of video information. Each layer may include at least one picture. The method can include processing an indicator within at least one of a video parameter set (VPS), a sequence parameter set (SPS), or a picture parameter set (PPS) that indicates whether all direct reference layer pictures associated with the at least one of the video parameter set (VPS), the sequence parameter set (SPS), or the picture parameter set (PPS) are added to an inter-layer reference picture set. Based on the indicator, the method can further include refraining from further signaling inter-layer reference picture information in any video slice associated with the at least one of the video parameter set (VPS), the sequence parameter set (SPS), or the picture parameter set (PPS). Alternatively, based on the indicator, the method can further include adding to the inter-layer reference picture set all direct reference layer pictures for any video slice associated with the at least one of the video parameter set (VPS), the sequence parameter set (SPS), or the picture parameter set (PPS).

    Abstract: In one example, a device for coding video data includes a video coder configured to code an intra random access point (IRAP) picture of a partially aligned IRAP access unit of video data, and code data that indicates, when performing random access from the partially aligned IRAP access unit, at least one picture of a video coding layer that is not correctly decodable. When the video coder comprises a video decoder, the video decoder may skip decoding of the pictures that are not correctly decodable, assuming random access has been performed starting from the partially aligned IRAP access unit.

    Abstract: In one implementation, an apparatus is provided for encoding or decoding video information. The apparatus comprises a memory configured to store inter-layer reference pictures associated with a current picture that is being coded. The apparatus further comprises a processor operationally coupled to the memory. In one embodiment, the processor is configured to indicate a number of inter-layer reference pictures to use to predict the current picture using inter-layer prediction. The processor is also configured to indicate which of the inter-layer reference pictures to use to predict the current picture using inter-layer prediction. The processor is also configured to determine an inter-layer reference picture set associated with the current picture using the indication of the number of inter-layer reference pictures and the indication of which of the inter-layer reference pictures to use to predict the current picture using inter-layer prediction.
