| Abstract: | The essence of a videoconference system today is the same as in those early prototypes. Users need at least one camera and sometimes several to record the participants in the meeting and to film flip charts or other items for display, plus microphones to pick up the sound. That information is then compressed and converted into a format that can be transmitted down the ordinary telephone line. But the last 10 years have seen two big changes in all this. First of all, the growth of the integrated services digital network (ISDN), which is now standard in some 25 coutries worldwide, has made it much easier to transmit digitally-coded information in this way. That means that videoconferencing systems can now be hooked up to the public telephone network instead of to specially-leased lines. |
