摘要： An apparatus of the present invention includes a viewer response system comprising a host site and at least one remote site interconnected by a satellite channel for host-to-remote video, an X.25 communications channel for message exchanges establishing a virtual circuit between each remote and the host site, and a dial-up public phone network channel that allows the host site to dial a remote site in response to a person at the remote site wanting to speak on the system to another person at the host site. A touch screen monitor at the host site allows the other person to sequence through electronic notecards that function as presentation cue cards. Questions can be formatted on remote site monitors and keypad terminals for each person at each remote site to allow real-time responses to be entered. A computer supporting the host site computes and displays remote site status and person's responses.
