摘要

A mobile telecommunication unit (20) provides two-way remote viewing of images and real time audio. The self-contained, portable unit (20) communicates directly with a similar unit at a remote location across POTS lines, cellular, ISDN, T-1, and satellite communication links. The unit (20) includes mass storage for archiving images. Input devices (25) for each unit include a digital camera (36) through a PCMCIA card, electronic stethoscope, telephone handset, speakerphone, external microphone, and serial and parallel ports. The output devices include a full color screen (22) for viewing local and received images and a speaker for audio output. A hard copy of images can be made by a video printer or desktop printer (42). Images can be uploaded to a PC.
