Utilizing MPEG Compression for High Quality Videoconference

MPEG set of compression standards enables high quality videoconferencing for services such as distant learning, telemedicine and business videoconferencing. Apart from all the requirements that have to be met in digital video transmission, in videoconferencing applications some specific issues arise. First we discuss requirements on transport network and codecs, if they are to be used in videoconferencing application. Then two different videoconferencing schemes are described, in which we experimented with key parameters to achieve the best possible presentation quality. Influence of different parameters is briefly discussed for each scheme.
