  • Video decoder with adaptive outputs
    Patent number: 8537890
    Abstract: In one aspect, there is provided a video decoder including a first write port to write uncompressed video data to a first buffer in a first format adapted based on a format required by the video decoder. The video decoder also includes a second write port to write uncompressed video data to a second buffer in a second format adapted to provide the uncompressed video data for subsequent processing external to the video decoder.
    Type: Grant

  • Method of synchronizing images on multiple display devices with different refresh rates
    Patent number: 7868848
    Abstract: A method for displaying images on multiple monitors with different refresh rates is disclosed. To prevent screen tearing, the surface containing image data is not released when the access by the master monitor is completed until the slave monitor or monitors finish access. To synchronize images with a predefined playback speed, the surface containing a new image received from the application is not flipped onto the screens until receiving a predefined synchronization indicator.
