Abstract
A video device having data lanes and a method of operating the video device includes obtaining a stream of debug data in response to a test operation, framing the stream of debug data independent of establishing a video blanking period, and transmitting the framed stream of debug data across one or more data lanes of the video link for operation between a video source device and a video sink device. The method also includes generating a stream of video data related to the test operation, framing the stream of video data to establish a video blanking period, and transmitting the framed stream of debug data concurrently with the framed stream of video data across the one or more data lanes of the video link.
