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.
