Abstract

본 발명은 브이씨알의 음성다중방송 수신장치에 관한 것으로, 종래 브리씨알은 변조기가 모노모드임으로 음성다중방송을 송신하여도 음성다중방송이 불가능한 문제점이 있었다.The present invention relates to an apparatus for receiving multiplexed voice multiplexed broadcast receivers. In the related art, the prioritized bryce has a problem in that the multiplexed voice broadcaster is impossible even though the multiplexer transmits the multiplexed voice broadcaster.

이러한 점을 감안하여 본 발명에서는 음성중간주파단에서 분리한 지표반송파를 포함한 음성신호를 변조하도록 회로를 구성하여 모노 또는 음성다중용 브이씨알에 관계없이 음성다중방송을 시청할 수 있도록 함으로써 소비자가 간단히 작동하도록 하여 제품의 신뢰도를 향상시킬 수 있다.In view of this, in the present invention, the circuit is configured to modulate the voice signal including the ground carrier separated from the voice intermediate frequency band, so that consumers can simply operate the voice multiple broadcast regardless of mono or voice multiplex VRC. The reliability of the product can be improved.
