    Abstract: Embodiments relate to half-duplex bidirectional transmission of data compliant with a first standard (e.g., Universal Serial Bus (USB) standard) over a physical channel of a multimedia link for transmitting audio/video (“A/V”) data compliant with a second standard (e.g., Mobile High-Definition Link (MHL) standard) between a source device and a sink device using time division multiplexing (TDM). The source device sends units of data including A/V data and forward data compliant with the first standard at first times whereas the sink device sends units of data including backward data compliant with the first standard at second times between transmissions from the source device. The first times do not overlap with the second times. Synchronization signals may be added to the first and second units of data to align character symbols embedded in the first and second units of data.

    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: A multimedia system for data communications. A source device communicates over a full duplex control channel of a multimedia communication link using time domain multiplexed (TDM) frames having n time slots per frame. The source device allocates a first time slot position to a virtual channel for data transmission by the source device over the full duplex control channel. A sink device communicates over the full duplex control channel of the multimedia communication link. The sink device allocates a second time slot position to the virtual channel for data transmission by the sink device over the full duplex control channel. A timing of the second time slot position is offset from a timing of the first time slot position by substantially n/2 time slots.
