  • Patent number: 10404624
    Abstract: A system for lossless switching of traffic in a network device may be implemented when a network switch is integrated into a gateway device, or with any other data source. A processor of the gateway device may receive queue depth information for queues of the network switch. The processor may prevent data from being transmitted to congested queues of the network switch, while allowing data to be transmitted to uncongested queues. In this manner, data loss can be avoided through the network switch for data sourced from the gateway device, such as audio-video data retrieved from a hard drive, audio-video data received from a tuner, etc. Furthermore, re-transmission at higher layers can be reduced. Since the subject system observes congestion for each individual queue, only traffic destined to that particular, congested, queue is affected, e.g. paused. Traffic to non-congested queues is not affected, regardless of traffic class or egress port.

  • Publication number: 20190130526
    Abstract: In the subject system for video warping, an electronic device may receive video data (e.g., from a video source). The electronic device may also receive or generate control information including view configuration information (e.g., for one or more viewports). The electronic device may warp a subset of the video data according to the view configuration information. The electronic device may process the warped subset of the video data using metadata associated with the video data. The electronic device may provide, for display, the processed subset of the video data. By warping the subset of the video data and then processing the warped subset of the video data, the system performs processing on the subset of the video data, instead of performing the processing the entire video data. In addition, the warped video data may be at a lower resolution than the original video data, which may require less resources for processing.
