Abstract

A video conferencing system (11) and method is disclosed for providing real-time audio/visual communications and data transfer between at least two device/system users over conventional POTS copper-wire based telephone lines, or T1/E1 telephone lines (39). The video conferencing system includes: a personal computer (13), a combination video and audio encoding and decoding circuit, a combination video display and audio input/output circuit, a sound sensing device, a digitizing circuit for transforming detected sound into digital audio, a continuous display camera (20) in electronic communication with the input/output circuit including an overlay feature for transforming detected visual images into a digital video signal, and a two way coder/decoder (CODEC) for combining the transformed digital audio and digital video signals into high-speed digital audio/visual signals.
