  • Protocol for digital audio-video interface
    Patent number: 9575917
    Abstract: Provided are methods and systems for selectively communicating data between a source device and one or more sink devices. The method includes generating a selection signal based on received configuration data associated with the sink device(s). Based at least in part on the selection signal, the data can be caused to be selectively provided to the sink device(s) by the first device. The data includes Universal Serial Bus (USB) protocol data, uncompressed high definition media data, or a combination thereof. In forward connections, the data may be provided variously at one of the following rates: 2.7 Gbps, 5.4 Gbps, 3.375 Gbps, and 6.75 Gbps. At 6.75 Gbps, the data may include a combination of USB data and audio/video data (having high resolution high definition video) or just standalone audio/video data (having higher resolution high definition video). In backward connections, the data includes USB data and can be transferred at either 2.7 Gbps and 3.375 Gbps.
