  • Patent number: 10231005
    Abstract: The present disclosure provides an operation instructing method and apparatus for a remote controller of an intelligent television, relating to the technical field of intelligent television. The method comprises: receiving an operation instruction from the remote controller; judging whether a user operation satisfies a preset instruction condition according to the operation instruction; and if so, displaying operation instruction information of the remote controller on a user operation interface, the operation instruction information being indicative of an operation of the remote controller. The present disclosure can solve the problem that since the service contents in the current intelligent television are numerous, and the operation mode varies with the service content, a misoperation will easily occur when certain service content is operated in a conventional operation mode, and the application of the service content is tedious and complex.

  • Patent number: 10104401
    Abstract: The latest High Efficiency Video Coding (HEVC) standard achieves significant compression efficiency improvement over the H.264 standard, at a much higher cost of computational complexity. A framework for software-based H.264 to HEVC transcoding on multicore processors and distributed systems is provided. By utilizing information extracted from the input H.264 bitstream, the transcoding process can be accelerated at a high ratio with modest visual quality loss. Wavefront Parallel Processing (WPP) and SIMD acceleration are also implemented to improve the trans coding efficiency on multi-core processors with SIMD instruction set extensions. Based on the HEVC HM 12.0 reference software and using standard HEVC test bitstreams, the proposed transcoder can achieve around 120× speed up over decoding and re-encoding based on ffmpeg and the HM software without significant R-D performance loss.

  • Patent number: 9112799
    Abstract: Embodiments of the present invention disclose a network packet loss processing method and apparatus. The method in the present invention includes: comparing a value of a current congestion window of a network with a buffer threshold when a packet loss event is detected, where the buffer threshold is used to indicate a data bearing capability of the entire network, where the data bearing capability is obtained by adding a data bearing capability of a link in the network and a data bearing capability of a buffer of a node in the network; if the value of the current congestion window is smaller than the buffer threshold, not performing backoff processing on the current congestion window; and if the value of the current congestion window is greater than or equal to the buffer threshold, performing backoff processing on the current congestion window.
