Method of real time optimizing multimedia packet transmission rate

An apparatus for continuous 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 separate a bi-directional auxiliary channel arranged to transfer information between the multimedia source device and the multimedia display device, comprising:

• means for providing a test pattern by the multimedia source device on the main link;
• means for 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;
• means for sending the bit error rate to the source device by way of the auxiliary channel;
• means for 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
• means for detecting a hot plug event that automatically determines when an active display device is connected to the main link and the auxiliary link;
• and
• means for commencing the optimization immediately subsequent to the detection of the hot plug event.
