Summary :

In this paper we propose a total quality evaluation method in an ATM network-type remote conference system, and describe the results of evaluations of a proving system. The quality of a remote conference system depends on such various elements as video images, voice signals, and cost; but a total quality index may be regarded as the cost of a remote conference system compared with that of a conventional face-to-face conference. Here, however, the decline in communication quality arising from the remote locations of participants must be included in the evaluation. Moreover, the relative weightings of voice signals, video images of participants, and shared data will vary depending on the type of conference, and these factors must also be taken into account in evaluations. An actual conference systems were constructed for evaluation, and based on a MOS (Mean Opinion Score) of the quality elements, the total system quality was evaluated with reference to the proposed concepts. These results are also described in this paper.
