METHOD AND SYSTEM FOR OPTIMIZING FORWARD ERROR CORRECTION OF MULTIMEDIA STREAMING OVER WIRELESS NETWORKS

摘要

THE LOSS OF PACKETS IN A COMMUNICATION SYSTEM CAN BE MINIMIZED IN AN OPTIMAL MANNER BY ADAPTING A SET OF ERROR CORRECTION (EC) PARAMETERS IN RESPONSE TO A CALCULATED PROBABILITY OF PACKET LOSS. THE CALCULATED PROBABILITY IS OBTAINED FROM DERIVED ALGORITHMS THAT ARE APPLIED TO A SET OF COMMUNICATION PARAMETERS (3, 5, 11, 21, 22). ALGORITHMS ARE DERIVED FROM BERNOULLI-DISTRIBUTED TRAFFIC MODELS AND CONSTANT BIT RATE (CBR) TRAFFIC MODELS OF THE COMMUNICATION SYSTEM. A COLLAPSED-STATE MODEL IS USED TO DERIVE A VERY EFFICIENT ALGORITHM THAT CALCULATES AN APPROXIMATE PROBABILITY OF PACKET LOSS. ALTERNATE APPLICATIONS FOR THE ALGORITHMS ARE ALSO DISCLOSED. FIGURE 1
