Abstract: Aspects relate to transmission of metadata from a source to a sink device, and optionally through one or more intermediaries. A source device encodes metadata into what would have been a blanking area of a field to be transmitted, according to a current video format. The source device encodes a timing for an active video data signal that is modified from a timing that would be used only for transmission of video data at a current resolution. A separate indicator from the source, or a negotiation between source and sink allows the sink to determine what part of the data indicated as being active video data is metadata, and to use that metadata for controlling aspects of the video display, and to use other parts of the received video data as video data for display. A sink can signal supported capabilities to a source.

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.
