INTER-DEVICE CONFLICT RESOLUTION ON A MULTIMEDIA LINK

摘要

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 through the full duplex control channel. The first arbitration logic ignores requests for receiving inbound control data from the sink device while the source device is transmitting outbound control data to the sink device. On the other hand, the sink device comprises second arbitration logic to control transfer of control data with the source device through the full duplex control channel. The second arbitration logic stops transmitting outbound control data through the full duplex control channel in response to receiving a request for receiving incoming control data from the source device.
