  • Publication number: 20220248054
    Abstract: Aspects of the disclosure include a method for point cloud coding. In the method, whether decoding of occupancy codes of nodes in a range of octree partition depths in an octree partitioning structure of a point cloud reaches a minimum octree partition depth at which parallel decoding is enabled is determined. Arithmetic coding information for decoding the occupancy codes of the nodes in the minimum octree partition depth is stored based on the decoding of the occupancy codes of the nodes in the range of octree partition depths reaching the minimum octree partition depth. The parallel decoding is performed on occupancy codes of the nodes in each of the at least one remaining octree partitions depth based on the stored arithmetic coding information. The point cloud is reconstructed based on the occupancy codes of the nodes in the range of octree partition depths in the octree partitioning structure.

  • Publication number: 20220232253
    Abstract: In some examples, an apparatus for point cloud compression/decompression includes processing circuitry. The processing circuitry determines a flag that indicates an enable/disable control for saving coding state in a largest coding unit (LCU) based coding of a point cloud. In some examples, the processing circuitry stores coding state information before a coding of a first LCU; and in response to the flag indicating an enable control, the processing circuitry restores, a coding state according to the stored coding state information before a coding of a second LCU. In some examples, in response to the flag indicating an enable control, the processing circuitry stores the coding state information before the coding of the first LCU. In some examples, in response to the flag indicating a disable control, the processing circuitry skip the storing/restoring of the coding state information.

  • Patent number: 11378225
    Abstract: Display assemblies for supporting displays on stands or support arms have mount portions to removably attach to the displays using magnetic assemblies and latches. The magnetic assemblies and latches can improve user experience and allow the display to be installed on a support arm from the viewing side of the display and without having to see or reach behind the display. Magnetic structures can center a mount portion of the support arm and a recess of the display and can attract them to each other. Laterally-extending latches can ensure the display is not inadvertently removed. Locking mechanisms can prevent the display from being rotated to a portrait orientation when sufficient space around the display and the necessary user intent is not provided.
