  • Patent number: 12005248
    Abstract: The invention relates to a rotor bearing system (1). Said system comprises a housing (80) in which a first permanent magnet (30) is mounted such that it can rotate about a first axis (105). A rotor (70) for conveying a liquid comprises a second hollow-cylindrical permanent magnet (40), which is mounted such that it can rotate about a second axis. The first permanent magnet (30) and the second permanent magnet (40) overlap axially at least partially, wherein the first permanent magnet (30) is disposed offset relative to the second permanent magnet (40). In the axial overlap region (160) of the first permanent magnet (30) and the second permanent magnet (40), the housing (80) is positioned between the two permanent magnets (30, 40).

  • Patent number: 12010340
    Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding. In some examples, an apparatus includes processing circuitry that identifies a reference sub-block in a previously reconstructed block of a picture. The processing circuitry determines whether reconstructed samples of the reference sub-block are included in an intra block copy search range according to a position of a current sub-block in a current block of the picture. The processing circuitry determines whether the reference sub-block is valid based on the reconstructed samples of the reference sub-block being determined as included in the intra block copy search range according to the position of the current sub-block. The processing circuitry further encodes the current sub-block based on the reconstructed samples of the reference sub-block in response to the reference sub-block being determined as valid.

  • Publication number: 20240187577
    Abstract: In a method for video decoding, prediction information of a current block is decoded from a coded video bitstream. The prediction information is indicative of a reference line selected from multiple reference lines and an intra prediction mode selected from a set of potential intra prediction modes that is associated with the reference line. At least one sample of the current block is reconstructed based on the intra prediction mode and at least one reference sample in the reference line. When the reference line is a non-zero reference line, a first set of potential intra prediction modes associated with the non-zero reference line includes a smaller number of potential intra prediction modes compared to a second set of potential intra prediction modes associated with a zero reference line. The first set of potential intra prediction modes only includes most probable modes.

  • Patent number: 12003748
    Abstract: A method for video encoding includes determining a parameter corresponding to the coded video bitstream based on a calculated maximum number of candidates. The parameter is in a range from 0 to 5-sps_sbtmvp_enabled_flag, where the sps_sbtmvp_enabled_flag equal to 1 specifies that subblock based temporal motion vector predictors are used. The sps_sbtmvp_enabled_flag equal to 0 specifies that the subblock based temporal motion vector predictors are not used. In response to a current block being in a subblock based prediction mode, the method includes encoding samples of the current block based on a candidate selection from a constructed subblock based merge candidate list of the current block. The constructed subblock based merge candidate list of the current block is constrained by the maximum number of candidates in the subblock based merge candidate lists.

  • Publication number: 20240179298
    Abstract: In a method for video decoding, a determination, for a current block that is a non-square block, is made as to whether an angular intra prediction mode for the current block is a wide angle mode that is in a direction outside of a range of directions that spans a bottom left diagonal direction and top right diagonal direction of the current block. When the angular intra prediction mode is the wide angle mode, whether a block size of the non-square block is greater than 32 is determined. When the block size of the non-square block is greater than 32, an intra smoothing filter is enabled and the enabled intra smoothing filter is applied to blocks neighboring the current block to generate filtered blocks. Intra prediction is performed based on the filtered blocks to obtain a characteristic value for the current block.

    Abstract: Aspects of the disclosure provide a method, an apparatus, and non-transitory computer-readable storage medium for video decoding. The apparatus includes processing circuitry that is configured to decode a current picture based on a bitstream. The processing circuitry can determine, from a supplemental enhancement information (SEI) message, a first flag indicating whether a warping process is applied to the current decoded picture. Based on the first flag indicating that the warping process is applied to the current decoded picture, the processing circuitry can determine warping information of the warping process based on the SEI message. The processing circuitry can determine a warped picture from the current decoded picture based on the warping information.
