Abstract:
1. A method of dynamically allocating communication resources in a video display interface located at a receiver and having a uni-directional main link that includes a plurality of communication lanes and a bi-directional auxiliary channel wherein neither the uni-directional main link nor the bi-directional auxiliary channel include clock signal lanes, wherein the uni-directional main link transfers video packets at a link character clock rate so that time base recovery is not performed on the video packets, and neither a transmitted clock signal nor time stamps are utilized at the receiver, the method comprising: allocating at least some of the communication lanes to transfer power; determining a portion of all remaining available communication lanes required to service a first multimedia function; and re-assigning at least some of the remaining available communication lanes to only carrying power from a power supply in a source device to a power circuit in a sink device when the portion of remaining available communication lanes required to service the first multimedia function is less than all remaining available communication lanes.
