摘要：
The invention relates to a receiver (100) for a broadcast signal, especially a car radio, and to a method for receiving a broadcast signal. According to the invention, a signal decoder (12) is provided which decodes an audio signal contained in an encoded manner in the broadcast signal and/or which decodes a data signal contained in an encoded manner in the broadcast signal. The signal decoder (12) is configured in such a way that a decoding of the encoded signal results only when the signal decoder (12) receives an external authentication signal which is received via an external transmission path that is different from a transmission path of the broadcast signal.
摘要（中）：
本发明涉及一种接收器（100），用于广播信号，尤其是汽车无线电，和用于接收广播信号的方法。 在此，信号解码器（12）被提供，其将加密的形式在广播信号中包括的音频信号和/或经加密的信号的解密仅发生时在广播信号中编码包含的数据信号，其中所述信号解码器（12）被形成为使得 信号解码器（12）接收通过不同的传输路径从所述广播信号中的一个时，外部传输路径，外部认证信号接收的信号。
