In addition, the central broadcasting unit 1 transmits the broadcasting data to the plurality of local broadcasting units 2 individually or in groups by real time or by scheduled operation according to a scheduled time by an operation of a teacher or a broadcasting member. In addition, the central broadcasting unit 1 can adjust the volume and tone of the broadcast data to be transmitted, and can also be transmitted by overlapping the character captions on the transmitted video data.

The local broadcasting unit 2 receives the broadcasting data transmitted from the central broadcasting unit 1 through the internal communication network 3 and broadcasts it through the TV 19 and the speaker 18, and the local broadcasting unit 2 itself. A separate broadcast data receiving means (13) and a local server (20) are provided to enable broadcasting, and a plurality of local broadcasting units (2) transmit internal broadcast data to other local broadcasting units (2). Are electrically connected together.

The local broadcasting unit 2 is provided in each classroom and the transceiver 11, the local server 20, the broadcast data receiving means 13, the communication port 15 and the TV 19 for outputting an image as shown in the drawing. And a speaker 18 for outputting voice.

The transceiver 11 receives broadcast data from the central broadcasting unit 1 and transmits and receives broadcasting data with the transceiver 11 of the other local broadcasting unit 2. Of course, not only the transmission and reception of broadcast data, but also signals related to broadcast conditions (time, frequency, volume, etc.) are also transmitted and received.

The broadcast data receiving means 13 is for receiving various broadcast data so that the local broadcast unit 2 can broadcast itself without passing through the central broadcast unit 1. That is, the broadcast data receiving means 13 receives broadcast data from an external device that stores broadcast data of video and sound sources such as a notebook, DVD, CD, VTR, and the like, and receives voice broadcast data for guide broadcasting from a microphone. An audio / video input control unit 14 for controlling whether to block or pass the broadcast data to be transmitted to the local server 20 is connected to the output side of the broadcast data receiving means 13.

That is, peripheral devices such as a fire detector for detecting the occurrence of a fire, a CCTV for monitoring a vulnerable area, and a thermal sensor for detecting an illegal intruder are connected, and transmit a signal from the peripheral device to the local server 20. The local server 20 receiving the signal sends out an evacuation broadcast or a guide broadcast stored in the memory 22 by a preset program or shows it as an image.

The local server 20 controls the local broadcasting unit 2 as a whole. That is, the image data is broadcast through the speaker 18 and the TV 19 or the broadcast data is transmitted to another local broadcasting unit 2 according to various signals input and preset programs.

The local server 20 may include a microcomputer 21, an IP interface unit 23, a remote control interface unit 25, a display unit 26, a USB port 27, a keyboard 28, a memory 22, and a decoder ( 29), the encoder 30 is made.

The IP interface unit 23 is connected to the Internet server for Internet communication, and the IP switch hub 24 is connected. The IP switch hub 24 is connected to a computer, an IP telephone, an IP TV, and the like. After the user (eg, teacher) authenticates through the IP interface unit 23, the user accesses the local server 20 and remotely controls his / her home to proceed with a separate video lesson or deliver a message. The student can reproduce and view various video data stored in the Internet communication and the memory 22 through a computer connected to the IP switch hub 24.

The remote control interface 25 is for remote control of the local broadcasting unit 2, the teacher remote control anywhere in the classroom to control the output of the broadcast on the TV 19 and the speaker 18 on / off, the image Pager can be flipped, etc., to increase the educational effect.

The USB port 27 is for downloading a variety of programs and broadcast data for the operation of the local server 20.

In addition, the keyboard 28 is for user's operation, and the user uses the keyboard 28 to store various broadcasting conditions in the memory 22 through the microcomputer 21 to schedule broadcast data to be broadcast so that the scheduled broadcast is performed. It is possible to broadcast by individual group by selecting another local broadcasting unit 2 to transmit broadcast data, and in case of overlapping broadcasting data to be broadcast, determine which broadcasting is to be prioritized by prioritizing broadcasting. This is possible. The broadcast time, broadcast repeat count, volume, and the like are also set at this time. In addition, it is also possible to set whether to block or receive and broadcast the broadcast data transmitted from the central broadcasting unit 1 or other local broadcasting units 2, and superimpose character captions on an image broadcast by the TV 19. You may.

The display unit 26 is an operating state of the local server 20, that is, whether the broadcast data is received through the setting of a broadcast condition through the keyboard 28 or the central broadcasting unit 1 or another local broadcasting unit 2. , By displaying whether or not the broadcast data receiving means 13 is operated to recognize the user.

The memory 22 stores various programs and various broadcast data for operating the local server 20. Broadcast data stored in the memory 22 is preferably stored in the form of MPEG4 file.

The decoder 29 decodes the image data transmitted through the broadcast data receiving means 13 or the central broadcasting unit 1 or the IP interface unit 23 and the image data stored in the memory 22 to generate a speaker ( 18) and transmits to the TV 19. The decoder 29 includes a video decoder for decoding an image, an audio decoder for decoding a sound source, and an MP3 decoder for decoding a sound source of a ringtone or a guide broadcast informing a class stored in the memory 22. The output side of the decoder 29 is connected to an audio / video output control unit 16 that controls whether to block or pass transmission of broadcast data output from the decoder to the speaker 18 and the TV 19. An audio amplifier 17 for amplifying a voice signal is connected to an input side of the 18).

The encoder 30 encodes the broadcast data input from the broadcast data receiving means 13 or the broadcast data stored in the memory 22 under the control of the microcomputer 21 and then performs other local operations through the transceiver 11. The broadcasting unit 2 is transmitted.

 The microcomputer 21 controls the local server 20 as a whole. That is, according to various programs stored in the memory 22 and various broadcasting conditions set through the keyboard 28 and control signals of the central broadcasting unit 1 or other local broadcasting units 2 input through the transceiver 11. The data is broadcasted through the TV 19 and the speaker 18 and transmitted to the other local broadcasting section 2, and the necessary of the received broadcast data is stored in the memory 22.

As such, each local broadcasting unit 2 can broadcast its own music, video, simple Chinese character learning, etc. according to the characteristics of the classroom through scheduled broadcasting during breaks and lunchtimes.

One local broadcasting station (2) allows control of all other local broadcasting stations (2), so that staff can be controlled by the whole school, grade level, and class in the nearest classroom (local broadcasting station (2)) rather than the central broadcasting room (central broadcasting station (1)). It is possible to broadcast broadcast data such as guide broadcasts and educational broadcasts, and even if an abnormality occurs in the broadcasting equipment of the broadcasting room (central broadcasting section 1), the broadcasting of each classroom (local broadcasting section 2) is not a major obstacle.

In the above description of the present invention with reference to the accompanying drawings has been described with respect to the IP-based multimedia broadcasting system capable of central control and local control having a specific shape and structure, the present invention can be variously modified and changed by those skilled in the art However, such modifications and variations are to be construed as falling within the protection scope of the present invention.
