A testbed for the evaluation of MPEG video transmission on ATM networks

Most of the new broadcasting and multimedia applications intensively rely on networked video. The current trend for distributing digital video on broadband ISDN networks is towards the adaptation of MPEG streams on ATM networks. End-to-end testing of such communication systems is very important and requires robust testing methodologies that are capable of evaluating both coding and transmission errors. This paper proposes a complete architecture for doing so. The system is entirely automatic, relies on synthetic test patterns and estimates the subjective quality of video coding and network transmission.
