  • Patent number: 11997271
    Abstract: An encoder partitions into blocks using a set of block partition modes. The set of block partition modes includes a first partition mode for partitioning a first block, and a second block partition mode for partitioning a second block which is one of blocks obtained after the first block is partitioned. When the number of partitions of the first block partition mode is three, the second block is a center block among the blocks obtained after partitioning the first block, and the partition direction of the second block partition mode is same as the partition direction of the first block partition mode, the second block partition mode indicates that the number of partitions is only three. A parameter for identifying the second block partition mode includes a first flag indicating a horizontal or vertical partition direction, and does not include a second flag indicating the number of partitions.

    Abstract: Provided is an encoder which includes circuitry and memory. Using the memory, the circuitry splits an image block into a plurality of partitions, obtains a prediction image for a partition, and encodes the image block using the prediction image. When the partition is not a non-rectangular partition, the circuitry obtains (i) a first prediction image for the partition, (ii) a gradient image for the first prediction image, and (iii) a second prediction image as the prediction image using the first prediction image and the gradient image. When the partition is a non-rectangular partition, the circuitry obtains the first prediction image as the prediction image without using the gradient image.

  • Publication number: 20240159956
    Abstract: In some embodiments, a head-mounted, near-eye display system comprises a stack of waveguides having integral spacers separating the waveguides. The waveguides may each include diffractive optical elements that are formed simultaneously with the spacers by imprinting. The spacers are disposed on one major surface of each of the waveguides and indentations are provided on an opposite major surface of each of the waveguides. The indentations are sized and positioned to align with the spacers, thereby forming a self-aligned stack of waveguides. Tops of the spacers may be provided with light scattering features, anti-reflective coatings, and/or light absorbing adhesive to prevent light leakage between the waveguides. As seen in a top-down view, the spacers may be elongated along the same axis as the diffractive optical elements. The waveguides may include structures (e.g.

  • Patent number: 11985699
    Abstract: A user equipment (UE) selects first and second radio resources from respective first and second pools of radio resources. In one example these are primarily allocated for contention-free and scheduling-based channel access, respectively. Content to duplicate in parallel communications is selected based at least on a characteristic of uplink data waiting to be sent (such as size) and/or on the selected first and second radio resources (such as timing difference between them). The UE transmits the selected content on each of the selected first and second radio resources. In the examples the content to duplicate was selected from among the uplink data to send and a scheduling request message. In various embodiments one of these transmissions indicates it's a duplicate, and the duplicated scheduling request message is transmitted on the first resource with the uplink data. These teachings are particularly useful for URLLC data.
