Abstract
A teleconferencing system includes desktop computers, external cameras anderipheral apparatus to allow interconnection of two or more terminals to engage in teleconferencing via digital data networks. A frame grabber interfaces each camera with its computer. Signals output from the computer are encoded and compressed before being input to a telephone line via a modulator/demodulator. A decoder is connected between the modulator/demodulator and the computer for decoding compressed video signals received by the modulator/demodulator means from the telephone line so that the signals may be displayed on a video display connected to the computer.
