The process of outputting the content information will be described in more detail. When the transmitting module 100 detects information of receiving modules to be set as a broadcast output target from an input means of the receiving module (S310), corresponding receiving modules are turned on ( Outputs an operation control signal (S320).

After that, when a request for selecting and outputting broadcast content information is input from a reception module to which a control signal is input, the broadcast content information is transmitted to the corresponding reception modules turned on in step S320 to be output through the screen display unit of the corresponding reception modules. (S330).

8 is a flowchart illustrating a remote control process of a multimedia broadcasting apparatus using a network clock according to the present invention, which will be described with reference to FIGS. 1, 2, and 8.

The transmission module 100 detects an operation control signal input from either a computer (not shown) connected through a network or a phone connected through the caller information receiving phone 170 (S400), and remotely through the computer. It is determined whether the connection is made through the telephone 170 or not (S410).

As a result of the determination in step S410, in the case of a phone connected through the caller information receiving phone 170, the user is allowed access by detecting the caller's phone number (S420) and comparing it with a user phone number previously stored in the database 112. It is determined whether or not (S430).

If the user's phone number is not allowed in step S430, the access is terminated. If the user's phone number is allowed, the user is guided to the connected telephone to perform user authentication. The code guide information is transmitted (S440).

That is, a number for authentication (for example, a password or a social security number) is detected from the telephone for user authentication and compared with an authentication number previously stored in the database 112. If the user is not authenticated, the connection is terminated.

After performing step S440, the transmitting module 100 analyzes a code signal (for example, a DTMF tone signal transmitted through a keypad of the telephone) input from the connected telephone to turn on / off the receiving module 200. The output of the broadcast content information and the like are controlled (S450).

That is, a function for controlling the operation of the transmitting module 100 and the receiving module 200 is provided for each code, and the corresponding operation is performed according to the code input from the telephone. For example, " 11 " is defined as all receiving modules on, and " 22 "

On the other hand, as a result of the determination in step S410, in the case of a computer connected to the network, the transmission module 100 performs authentication of the user connected to the computer (S421), and if the user is allowed as a result of the authentication in step S421, the computer The transmission module 100 controls the operation of the reception module 200 based on a control signal input from the reception signal.

9 and 10 are flowcharts illustrating a self-diagnosis process of a multimedia broadcasting apparatus using a network clock according to the present invention.

Referring to FIGS. 1, 2, 9, and 10, the transmission module 100 outputs a diagnostic signal for detecting the presence of an abnormality of the receiving modules, and the abnormality of the receiving modules according to the response of the diagnostic signal. Perform a self-diagnosis step to determine whether or not.

That is, when the diagnostic request signals of the receiving modules are detected (S500), the transmitting module 100 determines whether the diagnosis of the receiving modules is requested from the user or whether the diagnosis of the receiving modules is requested from the user (S510). .

When the diagnosis of the receiving modules is requested from the user in step S510, the transmitting module 100 detects information of the receiving modules requested by the user and outputs a diagnostic signal to the corresponding receiving modules (S520).

The transmission module 100 determines whether a response signal for the diagnostic signal is detected from the corresponding reception modules (S530). When the response signal is detected from each of the reception modules, the transmission module monitors (not shown) and Normal operation is displayed on the screen display unit 240 of each receiving module (S540), and a malfunction of the receiving module for which the response signal is not detected is displayed on the monitor of the transmitting module, and the screen display unit 240 of the corresponding receiving module is displayed. ) To be displayed (S541).

In addition, the detection result of the step S540 and the current state of the entire receiving module is stored in the database 112, and the current state of the entire receiving module is displayed on the monitor of the transmitting module (S550).

Meanwhile, when the diagnosis of the receiving modules is requested at a predetermined time in step S510, the transmitting module 100 outputs a diagnostic signal to all the receiving modules or simultaneously outputs the diagnostic signals to all the receiving modules in a preset order. To be made (S521).

After performing the step S521, the transmitting module 100 detects a response signal to the diagnostic signal from each receiving module (S522), and analyzes an operation state of all the receiving modules according to whether the response signal is received ( S523) Displayed on the monitor (not shown) of the transmission module or the screen display unit 240 of each receiving module, and stores the analysis result of the step S523 in the database (112).

As described above, the present invention has the advantage that it is possible to provide a variety of multimedia information in accordance with the correct time information, and a predetermined schedule of school broadcast.

In addition, since the remote control is possible, even if the user is not in the broadcasting room, the school broadcasting can be performed in the same manner as in the broadcasting room.
