1. A method of establishing an interactive audio and video conference in which the video signal is transmitted to the interactive sites via satellite, comprising the steps of:

  • connecting a plurality of interactive sites by means of telephone lines to a conferencing bridge to create a mix signal, connecting a first and second audio line between a television studio site and the bridge site, delaying any audio signal received from the studio site via the first audio line by an interval sufficient to compensate for differences between television and telephone transmission time, connecting the delayed audio signal to the bridge for inclusion in the mix signal for transmission via the telephone lines to the interactive sites, and creating a mix minus moderator signal and transmitting that signal via the second audio line to the studio site.
