Patent number: 10757481Abstract: An electronic device sends a content stream, via an unmanaged network, toward a client device and monitors the capacity of the unmanaged network. The device determines whether an aggregate bandwidth of an upcoming portion of the content stream fits the capacity. The upcoming portion of the content stream includes video content and user-interface data. In response to a determination that the aggregate bandwidth of the upcoming portion of the content stream does not fit the capacity, when the user-interface data is not the result of a user interaction: the device prioritizes a frame rate of the video content over latency for the user-interface data, and in accordance with a determination that the aggregate bandwidth of the upcoming portion of the content stream does not fit the capacity, sends ahead one or more frames of the video content in the upcoming portion, and delays the user-interface data in the upcoming portion.Type: GrantFiled: October 31, 2019Date of Patent: August 25, 2020Assignee: ACTIVEVIDEO NETWORKS, INC.Inventors: Ronald A.

Patent number: 10743029Abstract: Aspects of the disclosure provide method and apparatus for video coding. In some embodiments, an apparatus includes a processing circuitry. The processing circuitry decodes partition information of a block associated with a picture in a coded video bitstream. The partition information is indicative of a coding tree structure. Then the processing circuitry partitions the block into one or more coding blocks according to the coding tree structure. After the block is partitioned into multiple coding blocks, the processing circuitry groups the one or more coding blocks into non-overlapping grouped coding blocks such that each of the non-overlapping grouped coding blocks includes at least one coding block. Finally, the processing circuitry reconstructs the block based on the non-overlapping grouped coding blocks.Type: GrantFiled: December 28, 2018Date of Patent: August 11, 2020Assignee: Tencent America LLCInventors: Meng Xu, Xiang Li, Shan Liu

Patent number: 10708514Abstract: To extend dynamic range, a depth imager can expose a scene with two different exposures to obtain two depths. The two different exposures are selected to have respective depth ranges that overlap each other. The two depths can be combined by taking into account the difference in exposures and where the two depths are located with respect to boundaries of an overlapping range of the two depth ranges. The combination of the two depths in this manner can help avoid image artifacts such as contouring.Type: GrantFiled: August 30, 2018Date of Patent: July 7, 2020Assignee: ANALOG DEVICES, INC.Inventor: Rick Haltmaier

Patent number: 10708585Abstract: Intra prediction is used in state-of-the-art video coding standards such as AVC. The intra prediction modes are coded into the bitstream. Luma and chroma components could potentially have different prediction modes. For chroma components, there are 5 different modes defined in AVC: vertical, horizontal, DC, diagonal down right, and “same as luma”. Statistics show that the “same as luma” mode is frequent used, but in AVC, this mode is encoded using more bits than other modes during entropy coding, therefore the coding efficiency is decreased. Accordingly, a modified binarization/codeword assignment for chroma intra mode signaling is able to be utilized for high efficiency video coding (HEVC), the next generation video coding standard.Type: GrantFiled: August 8, 2019Date of Patent: July 7, 2020Assignee: SONY CORPORATIONInventors: Lina Dong, Wei Liu
