  • System and method for synchronizing multiple media devices
    Patent number: 8726061
    Abstract: Multiple media devices are synchronized in a multi-media system having a computer system, a plurality of media devices, and a display system. Each media device to be synchronized receives a front-end synchronization signal that periodically increments a front-end counter. The front-end counter represents an unadjusted system time (UST). The media device obtains a frame of data to be displayed from a computer system. The media device also receives a back-end synchronization signal that periodically increments a back-end counter each time a frame of data is to he displayed. The back-end counter represents a media stream count (MSC). UST and MSC data are periodically transmitted to the computer system for analysis and use by a synchronization algorithm. Specifically, UST is transmitted to the computer system each time a frame of data is obtained, and a UST/MSC pair is transmitted to the computer system each time a frame of data is displayed.
