The both direction control system for distributed multi-media
ABSTRACT: In order to overcome the disadvantages of traditional education method and bring into play the advantages of multiple education means, a multi-media education network system with the ability of interactive bidirectional control is constructed on the foundation of campus CATV (Community Antenna Television). Based on CAN bus and infrared remote control technology and with software-managed and authorization-controlled method, commands and information transmission can be bipolar between audio-visual education center and multi-media classrooms. With the multi-media education network system, the audio-visual education equipment in the audio-visual classrooms can be controlled in the multi-media classrooms. Taking advantages of this multi-media education network system will increase greatly the utilization ratio of audio-visual equipment and improve effectively the level of teaching and management.
