In this paper, an IP-based video lab-monitor system is proposed in order to efficiently supervise and manage the Electrical Engineering Example Lab Center of Hubei Province. The proposed system is composed of one Control & Display Unit (CDU) and a number of Lab View Units (LVU). The CDU is placed in the lab-supervisor’s office, while each LVU with a video camera is placed in one of the labs to be watched. The CDU and all LVUs are connected with an IP network. An LVU is mainly composed of 4 parts: Video Capture, Video Encoder based on H.263, Media Deliverer and Communication Controller. Accordingly, the CDU is composed of the following parts: a Center Controller, a Media Receiver, a Multi-Video Decoder and a Multi-Video Displayer. The supervisor can simultaneously watch the dynamic scene of 16 (4x4) labs on the CDU, with a resolution of 176 x 144 for each lab. He may choose to watch 4 (2x2) labs or only one lab at a time with higher resolution.
