に12でいる。C1 Conventional technology In audio multiplex broadcasting, audio different from the main channel audio is modulated with a subcarrier and transmitted along with the main channel, and the receiving side separates and extracts the main channel audio and the secondary channel audio, and then creates a stereo broadcast. I am at 12 so that I can listen to the audio of bilingual broadcasts.

る。Conventionally, a receiving apparatus for audio multiplex broadcasting is capable of selecting a receiving channel, as shown in FIG. The separated and demodulated audio channels A and B are switched and inputted to either one of the audio amplifiers 3.4 by a changeover switch 1.2,
The amplified outputs of both amplifiers 3.4 drive left and right speakers 5.6. The changeover switch 1.2 is switched in four ways by the changeover setting device 7, and as shown in the figure, channel A is output to the left speaker 5, and channel B is output to the right speaker 6.

ばならなくなってくる。D8 Problems to be Solved by the Invention In conventional audio reception, it is possible to switch between two channels of audio, but this switching is determined by the setting of the changeover switch. By the way, like recent satellite broadcasting, the main channel (Ach) broadcasts news in the native language,
For other broadcast programs, depending on the content being broadcast, the main channel may play a foreign language or the native language. In this way, when multiple languages are played randomly on the same audio channel, the recipient can choose which channel they want to listen to,
It becomes necessary to frequently operate the switching setting device 7 to match the language.

A native language identification device that identifies the language type from the acoustic parameters of each audio signal; and a native language identification device that preferentially captures and outputs audio signals that match the language type signal of the native language identification device and a preset language. and output audio selection means to identify the language type of the received and demodulated audio signal, and perform automatic switching to give priority to the audio output of the language that matches the set language.

同定装置9に取り込まれる。In FIG. 1, the audio signal of the main channel (Ach) is not only guided to the changeover switch 1.2 but also taken into the native language identification device 8. Similarly, the audio signal of the subchannel (Bch) is not only guided to the changeover switch 1.degree.2, but also taken into the native language identification device 9.

Identify which language the input audio signal will be in.

くよう切換スイッチ1.2を切換設定する。The output voice selection circuit 10 takes in the language type signal identified by the native language identification device 8゜9, and sets the native language setting Z+111.
The selector switch 1.2 is set so as to guide the audio signal of the language to be set to the audio amplifier 3.4.
こうした槽成において、主チャンネルに第2母国語の音

スイッチl。In this configuration, when an audio broadcast in the second native language is received on the main channel and an audio broadcast in the first native language is received on the sub channel, the first native language is set in the native language setting device 11. If so, the output audio selection circuit 10 selects the sub-channel audio signal from the language type signal for second native language identification from the native language identification device 8 and the language type signal for first native language identification from the native language identification device 9. The selector switch 1.2 is changed so as to lead to the amplifier 3.4, and the speaker 5.6 outputs audio in the first native language. In addition, in stereo broadcasting in which both the main channel and the sub-channel are the audio of the first native language, the main channel's audio signal is output to the speaker 5,
The audio signal of the subchannel is outputted to the speaker 6. Conversely, if both channels are different from the set native language, press the selector switch l.
2をそれまでの切換状態に保持させる。例えば、音声と
音楽が切り換えられるときには音楽には同定がなされず
、その前に音声で設定される切換状態に保持される。2 is held in the previously switched state. For example, when switching between audio and music, no identification is made for music, and the switching state previously set for audio is maintained.
なお、母国語設定器11に母国語設定がなされていない
ときや、全ての母国語が誤って設定された場合、出力音

換設定する煩わしい操作を不要にする。Therefore, according to this embodiment, even if the broadcasting station randomly changes the audio signal of one or more channels to multiple languages, the receiving side can always preferentially listen to the audio signal of the set native language. To eliminate the need for the troublesome operation of switching and setting every time the receiving language is changed, as in the past.

Even when the receiving side listens in the set language, the receiving side is automatically switched to listen in the set language, eliminating the need for the conventional troublesome operation of switching and searching for the desired language every time the language is changed.
