  • Patent number: 11039149
    Abstract: Techniques are provided for adaptively controlling an encoding device to allow dynamic insertion intra-coded video content based on feedback information. For example, at least a portion of a video slice of a video frame in a video bitstream can be determined to be missing or corrupted. Feedback information indicating at least the portion of the video slice is missing or corrupted can be sent to an encoding device. An updated video bitstream can be received from the encoding device in response to the feedback information. The updated video bitstream can include at least one intra-coded video slice having a size that is larger than the missing or corrupted video slice. The size of the at least one intra-coded video slice can be determined to cover the missing or corrupted slice and propagated error in the video frame caused by the missing or corrupted slice.

  • Patent number: 10817200
    Abstract: A flash memory controller is operative to receive serial commands and command arguments. A flash permissions table identifies each segment of flash memory as READ_ONLY, PRIVATE_R/W or OPEN_R/W. A memory interface is coupled to a flash memory and also the flash permissions table. When a flash memory write operation is received with an associated command argument corresponding to an address indicated as READ_ONLY in the flash permissions table and a DISABLE_WR_REG is true, the write operation is ignored or converted into a non-write command and issued to the flash memory.

    Abstract: Aspects of the present disclosure provide a method for compressing a point cloud. The method includes determining a sub-division technique for the volume based on one or more numbers derived from a distribution of points in the volume, dividing the volume into a number of sub-volumes according to the sub-division technique, and determining whether each sub-volume of the sub-volumes is occupied by at least one point. The method includes generating a bit sequence for the volume comprising a control code that is based on the sub-division technique and an occupancy indicator that indicates whether or not each sub-volume is occupied by at least one point.

  • Patent number: 10779011
    Abstract: Example techniques are described for image processing. Processing circuitry may warp image content of a previous frame based on pose information of a device when the device requested image content information of the previous frame and pose information of the device when the device requested image content information of a current frame to generate warped image content, and blend image content from the warped image content with image content of the current frame to generate an error concealed frame. A display screen may display image content based on the error concealed frame.
