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.
