Abstract: A system communicating over a full duplex control channel of a multimedia communication link by using synchronization signals that may also function as a logical link command. Synchronization indicators are exchanged between two communicating devices for maintaining synchronization of a logical link. At least two different types of synchronization signals may be sent between the two devices as synchronization indicators. A first synchronization signal is used by default to maintain synchronization of a logical link. A second synchronization signal is used in place of the first synchronization signal to maintain synchronization of the logical link. The second synchronization signal may be used to imply a virtual link command to indicate that a device is ready to receive data or has successfully received data over the virtual 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 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.
