Abstract: This thesis presents the study of the adaptation of MPEG video in ATM networks. The first part of the thesis provides a detailed description on the effects of cell loss on QoS for the MPEG video transmission in ATM networks. A real MPEG video sequence is used as the input source in the analysis. In the method, the MPEG video data is packetized into ATM cells. A cell discard pattern is generated using a Gilbert model to determine the occurrences of ATM lost cell due to buffers overflow in multiplexers. Subsequently, the effects of cell loss on QoS is evaluated by de-packetizing (assembling) the resultant ATM cells back into MPEG video data. The validity of our methodology is demonstrated by comparing the results of I-cell loss probabilities with those of the theoretical ones. The QoS evaluations presented in this thesis include high order distributions of cell loss from MPEG video sequence, subjective and objective evaluations of video quality under different network conditions. It has been observed that the effects of cell loss on QoS for the transmission of MPEG video in ATM networks depend on factors such as the burst cell loss length and the MPEG coding modes used.
