An adaptive chunk algorithm for flexible multimedia streaming

An adaptive chunk algorithm is newly devised for the quality of service maintenance of contents streaming under time varying bandwidth conditions as typically shown in Internet environment. A proxy-assisted streaming architecture is designed to incorporate the chunk algorithm, which adaptively compensates the effects of underflow in clients. A least mean square (LMS) based underflow estimation algorithm is designed for the compensation of underflow. The operation of the suggested algorithm is verified with computer simulations. The simulation result illustrates satisfactory compensation for the underflow at clients under simulated situations of abrupt drops of transmission rate
