Bi-directional digital interface for video and audio (DIVA)

摘要

A communication system, comprising a first node, a second node, a serial communication link between the first node and the second node, configured to transmit digital video data from the first node to the second node over one or more video channels of the link. The communication system further including a hybrid link between the first node and the second node, wherein the first node and the second node are configured to transmit at least one stream of data to the other through a hybrid channel over the hybrid link. In the communication system, the bandwidth of the serial communication link is scaled according to a video pixel frequency. Further, the initial locking of the serial communication link is aided by clock information delivered over the hybrid link.

1. A communication system, comprising:
a first node; a second node; a serial communication link between the first node and the second node, configured to transmit digital video data and an embedded clock signal from the first node to the second node over one or more video channels of the link, the embedded clock signal being embedded in the video data; and a high-bandwidth, bi-directional hybrid link between the first node and the second node wherein the hybrid link is a non-TMDS link, the hybrid link including one or more sub-channels for transmission of data; wherein the first node and the second node are configured to transmit at least a first stream of data to the other through a hybrid channel over the one or more sub-channels of the hybrid link; and wherein the hybrid link is configured to deliver a reference clock for the serial communication link, the hybrid link to switch from transmission of the reference clock to transmission of data via the one or more sub-channels including transmission of the first stream of data upon detection of an initial lock of the serial communication link, wherein the initial lock of the serial communication link is aided by the reference clock delivered over the hybrid link.
