Efficient multimedia delivery over digital subscriber line
Consider the design of a multimedia transmission system to provide reliable and efficient delivery of multimedia data over a digital subscriber line. The layers associated with different bit error performances are transmitted in parallel, and the properties of the telephone line channel are utilized to achieve unequal error protection efficiently. The transmitted power for the specified error performance is significantly reduced compared to that of conventional schemes. Simulation results are provided for subband-coded images and integrated services (video, voice and data), demonstrating an excellent performance improvement, where a 0.5-2 dB average power gain is achieved.
