  • Patent number: 10134106
    Abstract: A method of and device for providing image frames is provided. The method includes outputting portions of a first frame that have changed relative to the one or more other frames without outputting portions of the first frame that have not changed relative to the one or more other frames. Each of the portions are determined to be changed if a rendering engine has written to a frame buffer for a location within boundaries of the portion. This outputting is done in response to one or more portions of a first frame having changed relative to one or more other frames.
    Type: Grant

  • Patent number: 9760333
    Abstract: An apparatus includes a clock circuit and a virtual pixel clock circuit. The clock circuit provides a common clock signal. The virtual pixel clock circuit provides a plurality of pixel clock signals in response to the common clock signal. One of the virtual pixel clock signals is at a different clock speed than another of the plurality of virtual pixel clock signals.

  • Patent number: 9008591
    Abstract: An apparatus and method is provided for improving initialization and synchronization of display devices to audio data. Current implementations to retain synchronization between a transmitter and a display use “Keep Alive” silent audio data stream in the format of the latest data stream on an interface between the transmitter and the display even when no data is available. Implementing the above solution in a system where the silent audio data stream is transmitted over a wireless link is bandwidth and power inefficient. The techniques provide an apparatus and method to efficiently generate and transmit silent audio data stream for maintaining synchronization.

  • Publication number: 20120169745
    Abstract: Systems, methods, and computer readable storage mediums for arbitrating the sending of display data to a plurality of displays that are coupled to a controller are disclosed. A method for arbitrating display data requests for a plurality of displays coupled to a controller includes, providing display data to a display in the plurality of displays based upon a relative priority of the display amongst the plurality of displays.
