  • Patent number: 10972752
    Abstract: Systems, apparatuses, and methods for implementing stereoscopic interleaved compression techniques are disclosed. A system includes a transmitter sending a video stream over a wireless link to a receiver. For each pair of frames, the transmitter encodes a left-half of a first frame of the pair with an amount of compression less than a first threshold and encodes a right-half of the first frame with an amount of compression greater than a second threshold. For a second frame of the pair, the transmitter encodes a right-half of the second frame with an amount of compression less than the first threshold and encodes a left-half of the second frame with an amount of compression greater than the second threshold. The transmitter conveys encoded half-frames and indications of an amount of compression used for each half-frame to a receiver. The receiver receives, decodes, and drives the encoded half-frames to a display.

  • Publication number: 20200195944
    Abstract: Systems, apparatuses, and methods for adjusting the compression level for blocks of a frame based on a distance of each block to the focus region are disclosed. A system includes a transmitter sending a video stream over a wireless link to a receiver. The transmitter compresses frames of the video stream prior to sending the frames to the receiver. For each block of pixels of a frame, the transmitter selects a compression level to apply to the block based on the distance from the block to the focus region, with the compression level increasing the further the block is from the focus region. The focus region is the portion of a half frame where each eye is expected to be focusing when viewed by a user. The transmitter encodes each block with the selected compression level and then conveys the encoded blocks to a receiver to be displayed.

  • Publication number: 20190182308
    Abstract: Systems, apparatuses, and methods for implementing real-time, low-latency packetization protocols for live compressed video data are disclosed. A wireless transmitter includes at least a codec and a media access control (MAC) layer unit. In order for the codec to communicate with the MAC layer unit, the codec encodes the compression ratio in a header embedded inside the encoded video stream. The MAC layer unit extracts the compression ratio from the header and determines a modulation coding scheme (MCS) for transferring the video stream based on the compression ratio. The MAC layer unit and the codec also implement a feedback loop such that the MAC layer unit can command the codec to adjust the compression ratio. Since the changes to the video might not be implemented immediately, the MAC layer unit relies on the header to determine when the video data is coming in with the requested compression ratio.

  • Publication number: 20190104276
    Abstract: Systems, apparatuses, and methods for utilizing different modulation coding schemes (MCSs) for different components of a video stream are disclosed. A system includes a transmitter sending a video stream over a wireless link to a receiver. The transmitter splits the video stream into low, medium, and high quality components, and then the transmitter modulates the different components using different MCS's. For example, the transmitter modulates the low quality component using a lower, robust MCS level to increase the likelihood that this component is received. Also, the medium quality component is modulated using a medium MCS level and the high frequency component is modulated using a higher MCS level. If only the low quality component is received by the receiver, then the receiver reconstructs and displays a low quality video frame from this component, which avoids a glitch in the display of the video stream.

  • Publication number: 20190068983
    Abstract: Systems, apparatuses, and methods for sending hybrid frames as part of an encoded video stream are disclosed. A system includes a transmitter and a receiver communicating wirelessly. The transmitter partitions a first frame of a video stream into a plurality of portions and sends the plurality of portions to the receiver. The transmitter records which portions of the first frame which were not acknowledged by the receiver. Next, the transmitter generates one or more first portions of a hybrid frame based only on data from a second frame of the video stream and the transmitter generates one or more second portions of the hybrid frame based on a comparison of data from the second frame to data of the first frame. The one or more first portions of the hybrid frame correspond to portions of the first frame which were not acknowledged by the receiver.

  • Patent number: 9231792
    Abstract: An adaptive equalization system and operating method thereof are disclosed herein. According to an embodiment, an apparatus comprises a plurality of equalizers and control logic to selectively enable one or more equalizers of the plurality of equalizers and disable one or more other equalizers of the plurality of equalizers based, at least in part, on a quality of the channel over which the signal is received. In another embodiment, the apparatus includes first control logic to select an equalizer for a header of a packet and second control logic to select an equalizer for a data payload of the packet.
