摘要

Devices, systems and methods for sub-block based prediction are described. In a representative aspect, a method for video processing includes partitioning a first component of a current video block into a first set of sub-blocks and partitioning a second component of the current video block into a second set of sub-blocks. A sub-block of the second component corresponds to one or more sub-blocks of the first component. The method also includes deriving, based on a color format of the current video block, motion vectors for a sub-block of the second component based on motion vectors for one or more corresponding sub-blocks of the first color component.

說明書

The memory 1710 can be or include the main memory of the computer system. The memory 1710 represents any suitable form of random access memory (RAM), read-only memory (ROM), flash memory, or the like, or a combination of such devices. In use, the memory 1710 may contain, among other things, a set of machine instructions which, when executed by processor 1705, causes the processor 1705 to perform operations to implement embodiments of the presently disclosed technology.

Also connected to the processor(s) 1705 through the interconnect 1725 is a (optional) network adapter 1715. The network adapter 1715 provides the computer system 1700 with the ability to communicate with remote devices, such as the storage clients, and/or other storage servers, and may be, for example, an Ethernet adapter or Fiber Channel adapter.
