Publication number: 20230308823Abstract: A computer-implemented method for upmixing audiovisual data can include obtaining audiovisual data including input audio data and video data accompanying the input audio data. Each frame of the video data can depict only a portion of a larger scene. The input audio data can have a first number of audio channels. The computer-implemented method can include providing the audiovisual data as input to a machine-learned audiovisual upmixing model. The audiovisual upmixing model can include a sequence-to-sequence model configured to model a respective location of one or more audio sources within the larger scene over multiple frames of the video data. The computer-implemented method can include receiving upmixed audio data from the audiovisual upmixing model. The upmixed audio data can have a second number of audio channels. The second number of audio channels can be greater than the first number of audio channels.Type: ApplicationFiled: August 26, 2020Publication date: September 28, 2023Inventors: Aren Jansen, Manoj Plakal, Dan Ellis, Shawn Hershey, Richard Channing Moore, III

Patent number: 10554989Abstract: A method of encoding display output of a computer using a block-based video encoder, such as H.264 includes receiving display update information, the display update information specifying at least one changed display area. Pixel data associated with the at least one changed area is also received. For each image block of an output frame to be encoded, the encoder determines whether the image block intersects one or more of the changed areas. A block skip indication is encoded for each image block not intersecting at least one changed area, and pixel data is encoded for intersecting blocks. An encoded output frame is then generated including the block skip indications and encoded pixel data.Type: GrantFiled: June 20, 2014Date of Patent: February 4, 2020Assignee: DISPLAYLINK (UK) LIMITEDInventors: Dan Ellis, Eric Hamaker

Patent number: 10025351Abstract: A method for determining which of a plurality of mobile devices connected to the docking station is permitted to control the peripherals involves the docking station determining whether a new mobile device is connected to an input port of the docking station, and, if so, whether the new mobile device is capable of controlling any of the peripherals connected to the docking station. If it is determined that the new mobile device is not capable of controlling any of the peripherals, the docking station determines that the new mobile device is to be connected as a peripheral.Type: GrantFiled: July 9, 2015Date of Patent: July 17, 2018Assignee: DisplayLink (UK) LimitedInventor: Dan Ellis
