  • Publication number: 20220353497
    Abstract: This application provides a video picture decoding and encoding method and a video picture decoding and encoding apparatus. When it is determined that a merge or skip mode is used, if it is determined through decoding that a merge mode with motion vector difference (MMVD) indicator is true, a triangle prediction unit (PU) indicator may not be coded. The triangle PU indicator is coded when it is determined through decoding that the MMVD indicator is false. This reduces a quantity of used coding resources, and can reduce bit overheads of a bitstream.

  • Publication number: 20220349251
    Abstract: A vertical blind has a headrail, a transmission shaft, a plurality of slats located below the headrail with a gap, a driving assembly, a first clutch, a first pushing component, and a light-blocking member configured to be driven by the first pushing component to move from a blocking position coving the gap to a non-blocking position revealing at least a part of the gap. When the transmission shaft is driven to rotate in a first direction, the first pushing component is moved toward the first end of a movable region. When the first pushing component has been moved to the first end of the movable region and the transmission shaft keeps being driven to rotate in the first direction, the first clutch prevents the transmission shaft from further driving the first pushing component, whereby the first pushing component stays at substantially the first end of the movable region.
