Abstract

The effect of the ATM network usage parameter control function on VBR coded MPEG video is investigated. A video sequence is coded using MPEG and packetised into ATM cells. A simulated generic rate control algorithm (GRCA) function monitors the stream of cells and cells which exceed the connection parameters are dropped. The effect of these lost cells on the decoded video data is evaluated. Cells lost in this way severely degrade the quality of the decoded video data. We conclude that it is important to avoid UPC cell loss effects on video traffic
