  • Patent number: 11032574
    Abstract: In a method of video decoding in a decoder, a merge candidate list of a current coding block is constructed for processing the current coding block with a triangular prediction mode (TPM). The merge candidate list can include merge candidates each having one or two motion vectors. Each motion vector can be associated with a first reference picture list or a second reference picture list. A first motion vector and a second motion vector are determined from the motion vectors of the merge candidates on the merge candidate list. The current block is processed with the TPM with the first and second motion vectors as two motion vector predictors (MVPs) of two triangular partitions of the current coding block.

  • Patent number: 11032541
    Abstract: Aspects of the disclosure provide methods and apparatuses for video coding. In some examples, an apparatus includes processing circuitry. The processing circuitry determines first and second reference motion vectors for decoding a current block based on coding information of at least one previously decoded block, offsets a first component to obtain a shifted first component, and offsets a second component to obtain a shifted second component. The processing circuitry generates a third component, on the first coordinate axis, of a first averaged reference motion vector by adding the shifted first component and the shifted second component, and constructs a list of reference motion vectors incorporating the first and second reference motion vectors and the first averaged reference motion vector. The processing circuitry also determines a motion vector predictor using the list of reference motion vectors, and decodes the current block for output based on the determined motion vector predictor.

  • Patent number: 11021954
    Abstract: A method of recovering a room-and-pillar coal pillar by using external replacement supports. In the recovery of a room-and-pillar coal pillar, a cement material wall is formed by performing pouring around a coal pillar having a width to height ratio of less than 0.6, by means of a single-pillar sack arrangement technique, such that a coal pillar resource may be mined while a wall made from a cement filling material supports an overlying stratum. After mining is complete, a coal pillar goaf region is filled with the cement filling material, and after the cement filling material solidifies and is stable, the single pillar can be recovered.

  • Patent number: 11012704
    Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes receiving circuitry and processing circuitry. The processing circuitry decodes prediction information for a first block in a current picture from a coded video bitstream. The prediction information is indicative of an inter prediction mode that determines a first motion vector for the first block from a motion vector predictor. Then, the processing circuitry constructs, in responses to the inter prediction mode, a candidate list of candidate motion vector predictors with an exclusion from a plurality of second blocks that require one or more operations to finalize second motion vectors for the second blocks during a motion vector derivation.

    Abstract: The present invention relates to an allocation technology for wireless network resources, and particularly to a resource allocation method for coexistence of multiple line topological industrial wireless networks. The present invention considers the coexistence problem of multiple TDMA-based line topological industrial wireless networks, including three parts: lower bound analysis of scheduling delay, allocation algorithm of inter-network resources and allocation algorithm of intra-network resources. The method uses overall scheduling delay and resource utilization ratio as measurement indexes when analyzing the lower bound of delay and designing resource allocation algorithms, and selects a best node combination in each time slot to occupy as many channel resources as possible to improve the resource utilization ratio and reduce the overall scheduling delay.
