The present invention relates to an integrated broadcasting system for constructing smart classrooms, which combines the Internet with media devices to provide an integrated broadcast service. The integrated broadcasting system for constructing smart classrooms comprises: an input/output (I/O) device receiving and providing external power source, transmitting request information input by a user, and displaying a current channel number or a current time, a channel frequency, unused frequencies, a used frequency, an interference frequency, mute, SQL, scan, switch lock, and canceled switch lock according to a display operation control; a connector device including a video/audio connector, a network connector, a connector for a microphone/external input, a connector for speaker output, a connector for a hub, a connector for smart control, a USB connector, a RS-232 connector, and a power supply connector; a control device receiving power from the I/O device to be driven, transmitting and receiving data with an external device through the connector device, performing a control operation according to the request information transmitted from the I/O device, and controlling display operations of the I/O device according to infrared signals, audio signals, unused frequencies, used frequencies, and interference frequencies; and a receiving device receiving power from the I/O device to be driven, synchronizing a channel or a frequency with a transmitter and then transmitting an infrared signal and an audio signal, received from the transmitted, to the control device, performing auto frequency scanning, and transmitting scanned unused frequencies, used frequencies, and interference frequencies to the control device. |
