になる。 Now, when the program designation circuit 66 selects TV, the terminal P2 becomes low level, and the AND gate 56
is turned off, and AND gate 57 is turned on. As a result, the output of the video detection circuit 3 passes through the AND gate 57, is applied to the cathode ray tube 9 via the OR gate 59, and the amplifier 8, and is displayed. At this time, if the transmitted audio is a monaural signal, the output of the pilot signal detection circuit 74, that is, the terminal c, is at a low level, so the AND gate 751 is turned on and the signal 753 is turned off. At this time, if the output terminal d of the mode designation circuit 78 is at a high level (selecting the sub audio),
AND gate 752 is turned off and AND gate 756 is turned on. As a result, the monaural signal passing through 751 and 755 is output to AND gate 756 and OR gate 758.
The sound is emitted from the speaker 12 through the terminal f. Even if the mode specifying circuit 78 is at a low level (selecting the main audio), a monaural signal is output from the output terminal f through the AND gate 752 and the OR gate 758, so a monaural signal is output from the speaker 12 in any case. Of course, since a monaural signal is obtained at terminal e, monaural sound is output from the speaker 77. In the above case, since the terminal P3 is at a low level, no current flows through the coil of the relay 10, and one output of the OR gate 79 is at a low level due to the A-B short circuit. When the output of the video detection circuit 3 is displayed on the cathode ray tube 9, if the audio being sent is of a different type, the pilot signal detection circuit 74
When the pilot signal is detected, its output becomes high level. One output of the OR gate 50 becomes high level, but the AND gate 56 is off and there is no change in the video circuit. Furthermore, since the terminal c becomes high level, the AND gate 753 is turned on. At this time, Japanese will be added to terminal a and English will be added to terminal b, and Japanese will be output from the speaker 77, but if the mode designation circuit 78 requests sub-sound, the terminal d
becomes a high level, the AND gate 756 is turned on, and English, which is the sub-sound, is output from the speaker 12.

ぼつておけばよい。 Next, when a character is selected in the program designation circuit 66,
Since the terminal P2 becomes high level, the AND gate 56 is turned on and the AND gate 57 is turned off. In this state, if the transmitted audio signal is monaural and the P3 terminal of the control circuit 64 is at a low level, both inputs of the OR gate 50 are at a low level, so the AND gate 53 is turned on and the AND gate 52 is turned off. do. As a result, only the character signal from the main memory 65
AND gate 53, OR gate 55, AND gate 5
6. The image is projected onto the cathode ray tube 9 through the OR gate 59. At this time, monaural audio is output from the speakers 12 and 77, but since this audio does not match the image on the cathode ray tube 9, if it is unpleasant to the ears, the volume can be turned down.

べて関係があるので問題はない。 Next, when the program designation circuit 66 designates a text program that matches the content of the monaural audio signal, a high level signal is output from the control circuit 64 to the P3 terminal. This is because a special signal is recorded for a specific text program, and by detecting this specific signal, the above-mentioned high level signal is output. Since the terminal P2 is at a high level as described above, the AND gate 56 is turned on,
AND gate 57 is off. When the above P 3 is at a high level, the output of the OR gate 50 is at a high level, so the AND gate 52 is turned on and the AND gate 53 is turned on.
is turned off. As a result, both the output of the main memory 65 and the output of the video detection circuit 3 are outputted from the OR gate 51, passed through the AND gate 52, and displayed on the cathode ray tube 9. That is, a character signal is superimposed on a normal video and displayed. This character signal is projected in two horizontal lines at the bottom of the cathode ray tube. At this time, current flows through the coil of relay 10, so the switch of relay 10 becomes A-C short circuit, and R2 becomes high level. Then, the terminal d in FIG. 2 becomes a high level (at this time, the terminal c is a low level because the audio is monaural) and the AND gate 756
is on and 752 is off. As a result, the main voice (Japanese) coming through 755 is output to terminal f, and Japanese is output from speaker 12. Japanese is also output from speaker 77. In this case, there is no problem because audio, video, and text are all related.

る。 Next, when a character is selected by the program specification circuit 66 and the voices are of different types (Japanese and English), a pilot signal indicating that the voices are of different types is detected by the pilot signal detection circuit 74, Its output becomes high level. Then, the output of the OR gate 50 becomes high level, the AND gate 52 is turned on, and the AND gate 53 is turned off. As a result,
The video signal and the character signal pass through the OR gate 51 and pass through the gates 52, 55, 56, 59 to the cathode ray tube 9.
Both signals are output. In this case, as described above, if the specified text program is a specific one, the relay 10
A current flows through the terminal d, and the terminal d becomes a high level.Also, when the mode specifying circuit 78 manually specifies sub-audio, the terminal d becomes a high level. At this time, the second
Since both terminals c and d in the figure become high level,
AND gates 753, 756 are on, 751, 7
52 is turned off, the English language of terminal b is output from terminal f, and the sound is emitted from speaker 12. Japanese is output from speaker 77. When terminal d is at a low level (when the text program is not special and when mode designation circuit 78 designates main audio), both speakers 12 and 77 output Japanese.
