摘要： 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.

摘要： In one embodiment, an apparatus configured to code video data includes a processor and a memory unit. The memory unit stores video data associated with a first layer having a first spatial resolution and a second layer having a second spatial resolution. The video data associated with the first layer includes at least a first layer block and first layer prediction mode information associated with the first layer block, and the first layer block includes a plurality of sub-blocks where each sub-block is associated with respective prediction mode data of the first layer prediction mode information. The processor derives the predication mode data associated with one of the plurality of sub-blocks based at least on a selection rule, upsamples the derived prediction mode data and the first layer block, and associates the upsampled prediction mode data with each upsampled sub-block of the upsampled first layer block.

摘要： An apparatus configured to decode video data that comprises a memory configured to store the video data; and one or more processors. The one or more processors are configured to: receive a bitstream that is constrained such that escape values used in a palette mode for decoding the video data are no greater than a maximum value, wherein the bitstream includes information for determining at least one escape value representing a sample in a block of the video data to be decoded; and reconstruct the sample in the block of the video data using the information for determining the at least one escape value.
