Restricting inter-layer prediction based on a maximum number of motion-compensated layers in high efficiency video coding (HEVC) extensions
摘要
說明書
In accordance with some embodiments, an apparatus configured to code video information includes a processor and a memory. The memory is configured to store video information associated with a first layer and a second layer. The processor is in communication with the memory. The processor is configured to determine whether at least one of the first layer and the second layer is a default layer, and at least partially restrict inter-layer prediction when the processor determines that neither the first layer nor the second layer is the default layer.
In some embodiments, the default layer is a base layer. In other embodiments, the default layer is a layer 0. In other embodiments, the default layer is an enhancement layer. In some embodiments, there can be more than one default layer.
In some embodiments, the processor is further configured to receive a first flag associated with the video information and determine whether at least one of the first layer and the second layer is a default layer when the first flag indicates that inter-layer prediction is to be restricted. For example, the first flag can be signaled in one or more of a VPS (video parameter set), SPS (sequence parameter set), PPS (picture parameter set), slice header, and an SEI (supplemental enhancement information) message.
