  • Patent number: 12348765
    Abstract: A method of subblock-based temporal motion vector prediction is performed at a computing device. The computing device acquires a video bitstream including data associated with multiple encoded pictures. While decoding a current picture in the video bitstream, the computing device selects, according to syntax elements signaled in the video bitstream, one reference picture as a collocated picture of the current picture, and determines a temporal vector between the collocated picture and the current picture from motion information of spatially neighboring blocks of a current code unit (CU) according to a fixed order. Next, the computing device splits the current CU into multiple sub-CUs, obtains a temporal motion vector predictor for each sub-CU from the temporal vector and motion information of a block in the collocated picture that corresponds to a respective subblock of the current picture and decodes the current CU according to the temporal motion vector predictors.

  • Publication number: 20250211761
    Abstract: This application is directed to processing video data that includes a plurality of luma samples and a plurality of chroma samples corresponding to a plurality of pixel groups of a video frame. For each pixel group, an electronic device identifies a respective chroma sample and a set of luma samples and determines an anchor luma sample according to a predefined rule. A chroma refinement value is generated based on the set of luma samples by: obtaining a difference between a respective luminance value of each luma sample in the set and an anchor luminance value of the anchor luma sample, applying a cross component filter to the differences-luminance values of the set of luma samples to obtain a cross component filtering result, and performing a non-linear clipping operation based on the cross component filtering result. The electronic device derives a value of the respective chroma sample using the chroma refinement value.

  • Publication number: 20250211779
    Abstract: A video coder using bilateral template to perform decoder-side motion vector refinement is provided. The video coder receives receiving data for a block of pixels to be encoded or decoded as a current block of a current picture of a video. The current block is associated with a first motion vector referring a first initial predictor in a first reference picture and a second motion vector referring a second initial predictor in a second reference picture. The video coder generates a bilateral template based on the first initial predictor and the second initial predictor. The video coder refines the first motion vector to minimize a first cost between the bilateral template and a predictor referenced by the refined first motion vector. The video coder refines the second motion vector to minimize a second cost between the bilateral template and a predictor referenced by the refined second motion vector.

The electronic pressure control module is electrically connected to the low-pressure and high-pressure air compressors separately, and monitors an air pressure value of a to-be-inflated object. The air manifold element collects and outputs air from the low-pressure and high-pressure air compressors to the to-be-inflated object. When the air pressure value monitored by the electronic pressure control module is lower than a preset pressure threshold, the electronic pressure control module simultaneously controls the low-pressure and high-pressure air compressors to inflate the to-be-inflated object.
