Effects of ATM Transmission Errors on MPEG-2 Decoded Quality of Service

This paper describes an experiment that introduced bit errors and bursty cell losses into an MPEG-2 transport stream transmitted using AAL-5. The error-containing transport stream was decoded using a real-time MPEG-2 decoder in order to subjectively observe the effects of the errors on the video quality. We found that not all bit errors or cell losses cause visible degradation of decoded video. Furthermore, given the same bit error rate or ATM cell loss rate, it is desirable for the errors to be clustered rather than uniformly distributed. The result of this study may help to provide guidelines for designing ATM congestion control policies for networks carrying MPEG-2.
