摘要

A school multimedia broadcasting system having a remote control function is provided to control A/V(Audio/Video) function of usual broadcasting facilities remotely, manage facilities of a school integrally, and enable a user to control the function of a complex school broadcasting device easily with a PC by including an interface unit and a control PC. A control PC(100) controls/manages school broadcasting and the facilities remotely, and a main video device(200) broadcasts a video signal to a TV(810(1)-810(N)) of each classroom. A main audio device(300) transmits an audio signal to a terminal(900) of each classroom, and outputs a remote or manual control signal of the control PC to the terminal. The terminal is installed to each classroom, outputs the audio signal received from the main audio device to a speaker, and controls the facilities by receiving the control signal. An amplifier(600) amplifies the video signal output from the main video device to a predetermined level. Each grade distributor(800(1)-800(N)) distributes the amplified video signal into each classroom TV. The main video device is connected to the amplifier and the amplifier is connected to the distributor by using a coaxial cable.
