  • Low-latency consumption of an encoded video bitstream
    Patent number: 11252429
    Abstract: Systems, apparatuses, and methods for reducing latency when consuming an encoded video bitstream in real-time are disclosed. A video encoder encodes a video bitstream and writes chunks of the encoded bitstream to a bitstream buffer. Prior to the encoder completing the encoding of an entire frame, or an entire slice of a frame, a consumer module consumes encoded chunks of the bitstream. In one implementation, to enable pipelining of the consumption with the encoding, the encoder updates a buffer write pointer with an indication of the amount of data that has been written to the bitstream buffer. The consumer module retrieves encoded data from the bitstream buffer up to the location indicated by the buffer write pointer. In this way, the consumer module is able to access and consume encoded video data prior to the encoder finishing encoding an entire frame or an entire slice of the frame.

  • Exploiting camera depth information for video encoding
    Patent number: 11252430
    Abstract: The present disclosure is directed a system and method for exploiting camera and depth information associated with rendered video frames, such as those rendered by a server operating as part of a cloud gaming service, to more efficiently encode the rendered video frames for transmission over a network. The method and system of the present disclosure can be used in a server operating in a cloud gaming service to improve, for example, the amount of latency, downstream bandwidth, and/or computational processing power associated with playing a video game over its service. The method and system of the present disclosure can be further used in other applications where camera and depth information of a rendered or captured video frame is available.

  • Method for controlling a flexible capacitive touch display panel and touch display apparatus
    Patent number: 11249606
    Abstract: Embodiments of the present disclosure provide a method for controlling a flexible capacitive touch display panel and a corresponding touch display apparatus. The capacitive touch display panel is provided with a plurality of signal lines arranged in a grid shape, and a signal line extending in a first direction and a signal line extending in a second direction are electrically insulated from each other. In this method, for each of the plurality of signal lines, a drive signal is applied to the signal line as a drive signal line. An induction signal is received from a signal line parallel to and adjacent to the drive signal line as an induction signal line. If an intensity of the induction signal is increased, it is determined that the capacitive touch display panel is bent at a bending location between the drive signal line and the induction signal line.
