The terminal side T shown in the figure is one example of a large number of terminal sides T connected to the branch line 20 by a branch 21.

On the terminal side T, a converter 22 and a terminal device 23 are connected to the branch 21 via a modem 23a. The converter 22 receives the sent educational software on the CATV channel, converts the frequency to a designated channel of the television receiver 24, and outputs the same.

The terminal device 23 is also connected to a printer 23b1 and a keypad 25, and communicates with the head end control bag riL4 on the head end side H by polling, and controls the converter 22 to receive the educational software sent to it. While displaying on the machine 24, the student can use the key bat 25.
The response data is taken in and sent from the modem 23a to the head end side H via the branch 21.

A bidirectional amplifier 18 provided on the main line 17 amplifies the modulated downlink high frequency signal of educational software, broadcast waves, etc. transmitted through the main line 17 to compensate for attenuation in the transmission system. This is to amplify upstream high-frequency signals such as polling response signals from the transmitter to compensate for attenuation in the transmission system.

Next, the operation of the embodiment shown in FIG. 1 will be explained.

Figure 2 shows the content and operational concept of the educational software sent from the head end H. Figure 2 (A) shows the content of the educational software, and Figure 2 (B) shows the head end of the head end H. Processing time by the control bag VR14, FIG. 2(C) shows the head end control device from the terminal side T to the head end side H! This shows the response to 4.

Now, in the educational software of FIG. 2(A), a normal lecture E is given at the timing indicated by TI, and questions Q are asked to the students at the next timing T2. After question Q, T
Inquiry signal P is output at the beginning of timing 3.

This inquiry signal P can contain information such as the question number, the student's gender, age, and a signal indicating a specific classroom, and can be transmitted to video media such as video tapes and optical discs. This is recorded in advance using a cue signal or a tone burst wave in the audio band.

In response to this inquiry signal, each terminal T side
), the content of the inquiry signal is cut off, the question is accepted, and the response to the question is r#IJ r#2J...
- Perform "#n" using the key bat 25.

It has a function of printing out the statistical data according to the printer 23b.

Each of the many terminal devices 23 is preset with a unique designated address, and responds to the address of the polling signal generated by the head-end control device 14 in response to an inquiry signal within the educational software. Depending on the question, the numbers "1" to rnJ of the pad keys operated by the student on the key bat 25 are sent back to the head end side H as a response signal.

Note that the above explanation is for the case where one educational software subject is transmitted on channel -, but when multiple educational subjects are selectively transmitted to many groups, the following method is used. It becomes like this.

That is, the head-end control device 14 is connected to a large number of playback devices such as VTRs or optical disc players,
Each of the educational software is played back, and the created educational software is modulated onto different channels by the head end device f12, and then sent from the synthesizer 13 to the main line 17.

At this time, the head-end control device 14 uses a plurality of terminal devices 23 on the terminal side T in advance according to the contents of each subject of the educational software.
The above system can be realized by setting designated addresses for each and controlling the receiving channel of the converter 22 connected to the terminal device 23 of the terminal side T that has selected the subject subject. .

At this time, the head-end control device 14 tallies the response signals for each educational subject.

Furthermore, when sending statistical data f9 through statistical processing to the terminal side T, the terminal side T prints out the statistical data using the printer 23b. This statistical data is processed by the headend controller ft14!
If this is done, it is also possible to display it on the television receiver 24 on the terminal side T.

In this way, even when broadcast education is carried out from the head end H using a video playback device such as a VTR or optical disc player, the students do not just passively watch the lecture, but also listen to the content of the protest. You must respond to the appropriate questions. Therefore, the student's sense of participation can be sufficiently increased, and the student's understanding level can be confirmed by collecting the response results and performing statistical processing.

Additionally, this system can be further expanded to allow educational software to be sent from the center to multiple regions and statistics from processing devices to be centrally collected.

【Effect of the invention〕

As described in detail above, according to the present invention, in an educational system using two-way CATV, educational software in which an inquiry signal to start collecting responses from students is recorded as part of the content in advance is transmitted from a head-end device.
