Abstract

PURPOSE:To record the sound which is different from that under listening, by receiving the TV sound multiplex broadcast and switching each signal to supply it to a speaker or a recorder. CONSTITUTION:When the stereo broadcast is received, the demodulated signals of right and left sounds are applied to input terminals 10R and 10L and amplified by a stereo amplifier 1. These amplified signals are reproduced by speakers 5R and 5L and at the same time recorded by a sound recorder 11. In the same way, the monaural sound signals are reproduced by the speakers 5R and 5L and then recorded by the recorder 11 when the monaural broadcast is received. In a double broadcast mode, the demodulated signals of primary sound are applied to the terminals 10R and 10L, and the secondary sound is applied to an input terminal 12. As a result, it is possible to record the secondary sound by the recorder 11 connected to sound recording terminals 9R and 9L while listening to the primary sound through the speakers 5R and 5L. Furthermore the primary and secondary sounds can be switched to each other.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for receiving a television audio multiplex broadcast, reproducing the audio through a speaker, and recording the audio using a recording device.

In television audio multiplex broadcasting, for example, two languages (Japanese and English) are broadcast during double broadcasting, but conventionally, the same mode (Japanese language) as when viewing through the speakers of a television receiver is performed. ) was inconvenient in that it could only record audio. Therefore, it is not possible to watch television in Japanese and keep a recording of the English voice, or conversely, watch all television in English and keep a recording of the Japanese voice. There wasn't. However, listening to one Japanese language through a speaker while recording the audio of the other language is extremely useful in today's world where people are eager to learn foreign languages, and in ethnic nations with multiple languages. be.

Therefore, it is an object of the present invention to provide a device capable of recording audio other than what is being viewed.

FIG. 1 shows a three-page block diagram of a first embodiment of the invention. In the figure, reference numeral 1 denotes a stereo amplifier, which reproduces high-quality audio, and includes amplifiers 2R, 2L, 3R, and 3L consisting of two left and right channels, and a volume/sound quality control circuit 4. -! It also has output terminals 6R, 6L for speakers 5R, 5L, and recording output terminals 7R, 7L. On the other hand, 8 is a monaural amplifier. This has recording output terminals 9R and eL.

As a result, when receiving stereo broadcasting, input terminal 1oR9
The demodulated signals of the right and left voices are amplified by the stereo amplifier 1. Therefore, in this case, speaker 5
Good quality stereo sound with R, 5L? While having fun, you can record these by connecting the recording device 11 to the terminals 7R and 7L. Similarly, when receiving monaural broadcasts, input terminal 1
A monaural audio signal is added to both oR and 1oL, which is reproduced by the n1 speakers sR and sL, and can be recorded by the recording device 11vc.

In addition, during double broadcasting, the input terminal 10R, IOL is connected to the main audio (e.g. Japanese) (or sub audio (Japanese Patent Laid-Open No. 58-1
The demodulated signal of 53469 (2) (for example, English) is input to input terminal 12.
Since the opposite sub (or main) sound is added to the mode, connect the recording device 11 to the recording terminals 9R and 9L while listening to the main (or sub) sound through the speakers 5R and 5L, and listen to the reverse mode. All sub (or main) audio can be recorded by the recording device 11 .

Of course, it is also possible to record in the same mode as the output of speakers sR and sL.

In this way, for example, when receiving a broadcast in two languages, the actual audio is recorded, which is very useful for later language study. Moreover, since the monaural amplifier 8 is only needed when receiving dual broadcasts, it does not need to be stereo, and since it is used exclusively for recording output, there is no need to control volume, sound quality, etc., and the power is very high. Since it is small, it can be made extremely inexpensively.

FIG. 2 shows a second embodiment of the present invention, in which all inputs to the recording device 11 are switched by a switch 13R11sL.

In the case of the configuration shown in Figure 1, two recording devices 6.
Simultaneous recording of both English and English is also possible.

As described above, according to the invention, when receiving all television audio multiplex broadcasts, the stereo broadcast audio can be recorded on the recording device when receiving the stereo broadcast, and the main and sub audio can be arbitrarily recorded when receiving the dual broadcast. Can you listen to the main (or sub) sound while listening to the sub (or main) sound? It is possible to obtain a convenient device that can also record sound.
