Abstract

The end-to-end quality of service (QoS) of a variable bit rate (VBR) MPEG-2 compressed video transported over an interconnected ATM satellite-cable- terrestrial network incorporates the impact of the characteristics of these three media as well as the specificity of the video encoding/decoding processes. In this paper, we present the impact of a selected set of the QoS parameters on a number of VBR MPEG-2 encoded video clips on each segment of such internetworking. The QoS parameters used in our simulation include cell transmission delay (CTD), cell delay variance (CDV), cell misinsertion rate (CMR), and cell error ratio (CER). Also, we discuss and compare the quantified impact of bit error characteristics of satellite and fiber optics ATM systems. Objective and subjective results of our simulation show that the impact of the satellite segment on the MPEG-2 encoded video quality is comparable to that of the fiber optics system and to that generated from the VBR MPEG-2 video encoding/decoding process.
