Abstract
A source device communicates multimedia data to a sink device over a multimedia channel of a multimedia link. The source device comprises an interface to a full duplex control channel of the multimedia link. The source device also comprises first arbitration logic to control transfer of control data with the sink device via the full duplex control channel. The first arbitration logic ignores requests to receive inbound control data from the sink device while the source device is transmitting outbound control data to the sink device. The sink device, on the other hand, comprises second arbitration logic to control transfer of control data with the source device via the full duplex control channel. The second arbitration logic stops transmitting outbound control data via the full duplex control channel responsive to receiving a request to receive incoming control data from the source device.
