  • Publication number: 20210289224
    Abstract: This application provides an inter prediction method and a related apparatus. The method includes: parsing a bitstream to determine prediction information of a to-be-processed picture block, where when the prediction information indicates that a prediction direction of the to-be-processed picture block is bidirectional prediction, the bitstream does not include target identification information, where the target identification information is used to indicate to perform local illumination compensation LIC on the to-be-processed picture block; and obtaining a prediction value of the to-be-processed picture block based on the prediction information. According to the foregoing technical solutions, a video decoding speed can be accelerated without greatly affecting video quality.

  • Publication number: 20210185316
    Abstract: A picture partitioning method and apparatus are described. The method includes determining a split mode of a current node, where the current node includes a luma block and a chroma block. The method further includes determining, based on the split mode of the current node and a size of the current node, that the chroma block of the current node is not further split. In accordance with the chroma block of the current node not being further split, the method includes splitting the luma block of the current node based on the split mode of the current node. In accordance with the chroma block of the current node not being further split, the method may be used to split only the luma block of the current node, thereby improving encoding and decoding efficiency, reducing a maximum throughput of a codec, and facilitating implementation of the codec.

  • Patent number: 10838462
    Abstract: This application relates to adjusting an operation of a portable electronic device based on the detection of a protective case. A processor of the portable electronic device is configured to receive a signal that indicates the portable electronic device is in contact with and retained by the protective case. Responsive to receiving the signal, the processor is configured to allow the component to transition from a first operating state to a second operating state. The first operating state is associated with a first operating temperature that corresponds to a first temperature range at a surface of a housing for the portable electronic device. The second operating state is associated with a second operating temperature that corresponds to a second temperature range at the surface of the housing. The second operating temperature is greater than the first operating temperature.
