  • Patent number: 11949877
    Abstract: Innovations in adaptive encoding of screen content based on motion type are described. For example, a video encoder system receives a current picture of a video sequence. The video encoder system determines a current motion type for the video sequence and, based at least in part on the current motion type, sets one or more encoding parameters. Then, the video encoder system encodes the current picture according to the encoding parameter(s). The innovations can be used in real-time encoding scenarios when encoding screen content for a screen sharing application, desktop conferencing application, or other application. In some cases, the innovations allow a video encoder system to adapt compression to different characteristics of screen content at different times within the same video sequence.

  • Patent number: 11316682
    Abstract: The disclosure proposes a novel method for generating public polynomials. The method simplifies key exchange processes, reduces the time required for key exchange and reduces the bandwidth required for data transmission from a server to a client. Secondly, the method keeps the calculation processes at both sides synchronized through a novel data exchange solution, particularly through handshaking signals, to ensure that the server and the client are always in the same key exchange process. In addition, the method further reduces a transmission bandwidth by sending information of the client twice. A state synchronization mechanism of the client and the server is proposed in the disclosure to ensure that Trivium modules at both sides are in the same state at the beginning of each key exchange, thereby avoiding reinitializing the modules and improving the operation efficiency of the whole system.

  • Publication number: 20160035282
    Abstract: A pixel circuit for an active-matrix organic light-emitting diode display including an organic light-emitting diode and a driving circuit. The driving circuit includes six switches, a driving transistor, and a capacitor. By compensating the threshold voltage of the driving transistor, the electric current flowing through the organic light-emitting diode can precisely be controlled without influence by the threshold voltage of the driving transistor, increasing the luminance uniformity and stability of the display. Furthermore, the present invention can be applied to a depletion mode driving transistor (i.e., an oxide TFT). Thus, the threshold voltage can be obtained to proceed with compensation no matter the threshold voltage of the driving transistor is larger or smaller than zero.
