  • Patent number: 11503326
    Abstract: Systems and methods for integrated graphics rendering are disclosed. In certain embodiments, the systems and methods utilize a graphics engine, a video encoding engine, and remote client coding engine to render graphics over a network. The systems and methods involve the generation of per-pixel motion vectors, which are converted to per-block motion vectors at the graphics engine. The graphics engine injects these per-block motion vectors into a video encoding engine, such that the video encoding engine may convert those vectors into encoded video data for transmission to the remote client coding engine.

  • Patent number: 11503332
    Abstract: Systems and methods for reducing latency through motion estimation and compensation techniques are disclosed. The systems and methods include a client device that uses transmitted lookup tables from a remote server to match user input to motion vectors, and tag and sum those motion vectors. When a remote server transmits encoded video frames to the client, the client decodes those video frames and applies the summed motion vectors to the decoded frames to estimate motion in those frames. In certain embodiments, the systems and methods generate motion vectors at a server based on predetermined criteria and transmit the generated motion vectors and one or more invalidators to a client, which caches those motion vectors and invalidators. The server instructs the client to receive input from a user, and use that input to match to cached motion vectors or invalidators. Based on that comparison, the client then applies the matched motion vectors or invalidators to effect motion compensation in a graphic interface.

  • Patent number: 11496755
    Abstract: Aspects of the disclosure provide a method and an apparatus including processing circuitry for video decoding. The processing circuitry decodes, from a coded video bitstream, coding information for a current picture. The coding information indicates that a geometric merge mode is enabled for a coding level higher than a picture level of the current picture and a maximum number of merge candidates satisfies a condition. The processing circuitry determines, based on a picture level parameter signaled for the current picture in the coded video bitstream, a maximum number of geometric merge mode merge candidates based on the picture level parameter and the maximum number of merge candidates. The maximum number of geometric merge mode merge candidates can be (i) 0 or (ii) one of 2 to the maximum number of merge candidates. The picture level parameter indicates the maximum number of geometric merge mode merge candidates.

  • Patent number: 11405689
    Abstract: Systems and associated methods are described for providing recording of a blacked out media content item. A system receives a request from a first user device associated with a profile to record a media content item scheduled to broadcast on a second user device (different from the first user device) associated with the profile, at a second location. The system determines that the media content item is subject to a blackout during a blackout period within a blackout region. The system determines that the first user device and the second user device are associated with the same profile and that the first user device is at a first location outside the blackout region. The system then accesses the media content item for recording on the second user device during the blackout period. The system further transmits the recorded media content item to the first user device after expiry of the blackout period.
