    Abstract: An apparatus for interfacing with a multimedia communication link comprises a half-duplex translation layer circuit operating in half-duplex and a full-duplex link layer circuit to communicate over a control bus of the multimedia communication link in full duplex. The apparatus further comprises an arbitration circuit communicatively coupled between the half-duplex translation layer circuit and the full-duplex link layer circuit, the arbitration circuit to control data flow between the half-duplex translation layer circuit and the full-duplex link layer circuit. The arbitration circuit provides interface and signaling rules for transmitting packets from the half-duplex translation layer circuit to the full-duplex link layer circuit, receiving packets via the full-duplex link layer circuit at the half-duplex translation layer circuit, and resolving conflict arising due to bidirectional data flow at the arbitration logic.

    Abstract: In one embodiment, a source device and sink device communicate with one another via a multimedia link. The multimedia link includes a cable and a plug. The cable includes one or more data lines, power lines, ground lines or control bus lines. The plug includes a plurality of pins each connected to the one or more lines included in the cable. The plug also includes a ground plane and a power plane, wherein a ground pin of the plug connects the ground plane to the ground line of the cable of the multimedia link and a power pin of the plug connects the ground plane to the power line of the cable. In one example, the ground plane and power plane are placed within a threshold distance of one another, such that the power line connected to the power plane via the power pin behaves as a signal return path.

    Abstract: Embodiments of the present disclosure are related to identifying the orientation of a multimedia link connected between a source device and a sink device. A sink device includes a plurality of pins that are configured to interface with a plurality of pins of the multimedia link. The sink device identifies based on the values of one or more pins of the plurality of pins of the sink device whether the multimedia link is connected to the sink device. Further, the sink device determines an orientation of the multimedia link connected to the sink device. The multimedia link can be in one of two orientations, straight or flipped. The sink device may communicate the orientation of the multimedia link to the source device. The source device may perform lane mapping based on whether the multimedia link is in the straight or flipped orientation.

    Abstract: Embodiments of the invention are generally directed to multiple protocol tunneling using time division operations. An embodiment of an apparatus includes an interface for communication with a second apparatus, the interface including a shared communication link; and a multiplexer to multiplex data of each of multiple protocols into time slots for transmission, the protocols including a first protocol. The time slots are distributed among the protocols, where the distribution of the time slots among the protocols includes assigning one or more time slots to the first protocol to enable the data of the first protocol to meet one or more performance requirements for the first protocol.
