Abstract
A system and method for providing digital AV signal to multiple displays where the digital AV signal is displayed simultaneously and sychronized. Exemplary embodiments utilize serializers, de-serializers, and clock cleaners to transmit the data to a chain of display nodes. The display nodes convert the serial data stream into a parallel data stream. The parallel data stream is de-jittered and used to drive a display and optional audio system. The parallel data stream is then converted back into a serial data stream and sent to the next display node in the chain. A clock present in the data stream allows synchronization of all the displays in the chain. A distribution display node may be used at any display node location to increase the number of chains in the data delivery system.
