Abstract
A system and a method for exchanging communication data between devices using a bi-directional communication channel are disclosed. A combiner is coupled to a source device via first bi-directional configuration channel and to a sink device via a second bi-directional configuration channel. Upon receiving data from the first bi-directional configuration channel and not receiving data from the second bi-directional configuration channel, the combiner transmits the received data to the sink device using the second bi-directional configuration channel and prevents data transmission from the sink device to the source device using the second bi-directional configuration channel. Similarly, upon receiving data from the second bi-directional configuration channel and not receiving from the first bi-directional configuration channel, the combiner prevents data transmission from the source device to the sink device and transmits the received data to the source device using the first bi-directional configuration channel.
