Patent ID: 7620062

Claim:
A method of real time optimizing transmission of a number of multimedia data packets between a multimedia source device and a multimedia display device coupled by way of a unidirectional main link arranged to carry the multimedia data packets from the multimedia source device and the multimedia display device and a separate bi-directional auxiliary channel arranged to transfer information between the multimedia source device and the multimedia display device, comprising: providing a test pattern by the multimedia source device on the main link; determining a transmission quality factor of the main link by determining a bit error rate by the multimedia display device based upon the test pattern; sending the bit error rate to the source device by way of the auxiliary channel; optimizing the transmission of the multimedia data packets based upon the transmission quality factor if the bit error rate is greater than a predetermined threshold value bit error rate; and detecting a hot plug event that automatically determines when an active display device is connected to the main link and the auxiliary link; and commencing the optimization immediately subsequent to the detection of the hot plug event.
