摘要： This invention provides a video conversation/monitoring system that has a remote monitoring function and remote peripheral device control function in addition to a video-phonic conversation function, and is suitable for various user-intended guidance services. The system consists of a center station (2) and multiple end stations (3, 4) linked through the ISDN network (1). The center station includes a video conversation/monitoring means (5), video input means (7), video output means (6), audio input means (30), audio output means (28), system controller (9), facsimile (8) and ISDN line terminating unit (14), and each end station includes a video conversation/monitoring means (10), system controller (16), first video input means (12), second video input means (15), audio input means (321), audio output means (322), calling means (29), first notification means (110), second notification means (109), detection means (108), facsimile (13) and ISDN line terminating unit (14). Based on the remote monitoring function of the video input means and the remote control function of the system controller for switching the video input means, various guidance services are accomplished in addition to the video-phonic conversation service. The integrated unit enables easy desk-top installation, the application of the ISDN network reduces the communication cost, and the provision of various state detection means in the end stations enables the image-based monitoring and state monitoring in addition to the conversation.
