In teleconferencing, conversation should flow naturally between separate sites. The acoustic design should, of course, be able to at least convey the correct volume. However, sound localization is also very important for realizing kind virtual reality world that teleconferencing. Coordinating visual image (a speaker’s face) and (his or her voice) creates a environment in which participants each site feel as if they are having same room. Two prototype teleconferencing systems with effects have been developed. more primitive two small system can connect sites stereo reproduction way utilizes psychological phenomena. other high-presence aims achieving high level ambience among three Its features key technologies natural images on large super-high-resolution display, good from remote locations through use multichannel system, high-definition result HDTV coding transmission. proposed comprises four subsystems, one input, reproduction, feedback control,
