Method and device for providing high speed data transmission with video data

摘要

A method and device for operating a data link having multiple data lanes is provided. The method includes supplying first data (such as video data that follows the DisplayPort protocol) on one or more data lanes of a data interface between a video source device and a video sink device. In addition to being video stream data (such as the above mentioned DisplayPort video data) the first data can also be audio stream data (such as DisplayPort audio data), source-sink interface configuration data (such as DisplayPort AUX data) and sink related interrupt data (such as DisplayPort Hot Plug Detect “HPD” data). The method also includes receiving second data on one or more unidirectional data lanes of the data interface. The second data being data other than video stream data, source-sink interface configuration data and sink related interrupt data.

1. A method of operating a data link having data lanes including:
supplying first data on one or more high-speed data lanes of a data interface, the interface including at least five high-speed data lanes for operation between a video source device and a video sink device, each of the at least five high-speed data lanes operable to transmit data at greater than 1 G bit/sec, the first data including one or more of video stream data, audio stream data, and source-sink interface configuration data and sink related interrupt data; and receiving second data on one or more of the at least five high-speed data lanes of the data interface, the second data being data other than video stream data, audio stream data, source-sink interface configuration data, and sink related interrupt data.
