Modeling and simulation of MPEG-2 video transport over ATM networks considering the jitter e ect

Abstract- In this paper, the operation of MPEG-2 systems is modeled and simulated when an MPEG-2 transport stream is delivered through a ATM network with jitter. A novel approach to analyzing; the decoder buffer behavior in the presence of network jitter is presentetd. The prob-ability density function of the interarrival time of the ATM adaptation layer 5 (AAL5) Protocol Data Unit (PDU) is derived from a MPEG-2 video source model and an ATM network jitter model. Based on a real-time decoding requirement of the MPEG-2 transport stream (TS) system target decoder (T-STD), the decoder buffer behavior is simulated. The modeling and simulation results show that jitter affects decoder buffer size and packet loss ratio in a significant way
