Abstract:
1. A compact packet based multimedia interface arranged to couple a portable multimedia source arranged to provide a reduced set of multimedia formats each at a native multimedia clock rate and a multimedia display; comprising: a uni-directional main link having no more than two pairs of twisted conductors each pair forming a single communication channel coupling the multimedia source to the multimedia sink arranged to carry a packetized multimedia data stream from the multimedia source to the multimedia display at a link character clock rate that is independent of the native multimedia clock rate so that no time base recovery of the packetized multimedia data stream is necessary, wherein the uni-directional main link is coupled only to a transmitter at the multimedia source and a receiver at the display, wherein neither a transmitted clock signal nor time stamps are utilized at the multimedia sink; a half duplex, bi-directional auxiliary channel connecting the multimedia source and the display that provides in concert with the uni-directional main link, a secondary communication link between the multimedia source and the display for transferring information between the multimedia source and the display, wherein the half-duplex, bi-directional auxiliary channel is coupled to both a transmitter and a receiver at the multimedia source and both a transmitter and receiver at the display; and the uni-directional main link and the secondary communication link being physically distinct pairs of twisted conductors and lacking a clock lane.
