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.

Abstract translation: 源设备通过多媒体链路的多媒体信道将多媒体数据传送到宿设备。 源设备包括到多媒体链路的全双工控制信道的接口。 源设备还包括第一仲裁逻辑，以经由全双工控制信道来控制与宿设备的控制数据传输。 第一个仲裁逻辑忽略了在源设备向出站设备发送出站控制数据时从宿设备接收入站控制数据的请求。 另一方面，宿设备包括第二仲裁逻辑，以经由全双工控制信道来控制与源设备的控制数据传输。 第二仲裁逻辑响应于接收到从源设备接收传入控制数据的请求，经由全双工控制信道来停止发送出站控制数据。
