Executive Summary

In this paper, a measurement system is proposed for the test of the DVB (Digital Video Broadcasting) receivers. In this an analysis of baseband transmission channel parameters in DVB Video signal is performed. The simulation model proposed take in account the evaluation of subjective picture quality. In this paper, an analysis of video quality of compressed MPEG-4 stream is performed. The video quality is performed using a test system composed by two metering devices: TEKTRONIX PQA500 picture quality analyzer and TEKTRONIX MTS4EA elementary stream analyzer. The measured parameters of compressed MPEG-4 signal are: macro block measurements and PSNR.
