  • Publication number: 20230119972
    Abstract: Video encoding methods and apparatuses for performing rate-distortion optimization by a hierarchical architecture include receiving input data associated with a current block in a current picture, determining a block partitioning structure to split the current block into coding blocks and determining a corresponding coding mode for each coding block by multiple Processing Element (PE) groups, and entropy encoding the coding blocks in the current block according to the coding modes determined by the PE groups. Each PE group has parallel PEs and is associated with a particular block size. The parallel PEs in each PE group test a number of coding modes on each partition or sub-partition of the current block to derive rate-distortion costs. The block partitioning structure and corresponding coding modes are then decided based on the rate-distortion costs derived by the PE groups.

  • Publication number: 20230087875
    Abstract: Image or video processing methods and apparatuses comprise receiving input data associated with a current picture or a current slice in the current picture, determining whether the current picture is a monochrome picture, conditionally signaling or parsing chroma deblocking parameters depending on whether the current picture is a monochrome picture, and encode or decode the current picture or current slice. The chroma deblocking parameters are used in a deblocking filter operation applied to chroma components of the current picture or current slice when the current picture is not a monochrome picture. A syntax element may be used to indicate derivation of chroma deblocking parameters, and based on a value of the syntax element, the chroma deblocking parameters are allowed to be explicitly signaled in or parsed from a syntax structure, or the chroma deblocking parameters are implicitly inferred.

  • Publication number: 20230054633
    Abstract: Techniques described herein enable respective (different) types of metal silicide layers to be formed for p-type source/drain regions and n-type source/drain regions in a selective manner. For example, a p-type metal silicide layer may be selectively formed over a p-type source/drain region (e.g., such that the p-type metal silicide layer is not formed over the n-type source/drain region) and an n-type metal silicide layer may be formed over the n-type source/drain region (which may be selective or non-selective). This provides a low Schottky barrier height between the p-type metal silicide layer and the p-type source/drain region, as well as a low Schottky barrier height between the n-type metal silicide layer and the n-type source/drain region. This reduces the contact resistance for both p-type source/drain regions and n-type source/drain regions.

  • Patent number: 11589050
    Abstract: Video processing methods comprise receiving input data of a current block, checking whether the current block is a root block by considering one or more predefined criteria, applying a mode constraint, a chroma split constraint, or both the mode and chroma split constraints to the current block if the current block is set to be a root block, and encoding or decoding the current block. The mode constraint restricts all blocks split from the current block to be processed by a same prediction mode and the chroma split constraints prohibits chroma components of the current block to be further partitioned while allowing a luma component of the current block to be partitioned into smaller blocks.

  • Patent number: 11536811
    Abstract: A distance measuring device includes a pulsed laser source, a light receiving unit and a computing module. The pulsed laser source emits a laser pulse to a target in accordance with a predetermined period. The light receiving unit has a photon receiving type of light receiving element that receives incident light and outputs a binary pulse, and the binary pulse is used to indicate whether a photon receiving event occurs. The computing module is configured to receive the binary pulse and determine whether an inter-period coincidence event occurs, and the inter-period coincidence event is defined by detecting a plurality of photon receiving events exceeding a predetermined count, on relative positions in a predetermined period number of the predetermined periods. If the calculation module determines that the inter-period coincidence event occurs, a distance of the target is calculated according to time information related to the inter-period coincidence event.

  • Publication number: 20220385889
    Abstract: A method and apparatus for video coding using Intra prediction are disclosed. In one method, a first prediction sample in an immediately right column of the current block and a second prediction sample in an immediately below row of the current block are derived using angular prediction. The first prediction sample and a left column reference sample in the same row as the first prediction sample are interpolated to generate a horizontal predictor. The second prediction sample and an above-row reference sample in the same column as the second prediction sample are interpolated to generate a vertical predictor. The vertical predictor and the horizontal predictor are linearly combined to generate an angular-planar prediction sample. In another method, a first predictor is generated using angular prediction and a second predictor is generated using planar prediction. The first predictor and the second predictor are linearly combined to generate a fused Intra predictor.
