    • A DTV module includes a CPU, a decoder, and a CA interface circuit. The decoder executes a decoding processing on a digital television signal inputted from a demodulator provided on a motherboard, so as to decode the digital television signal into a video signal and an audio signal, and outputs the video signal and audio signal. The CA interface circuit is connected to a CA module via a PC card socket, and executes input and output processings on signals communicated among the demodulator, CA module, decoder, and CPU. The CPU controls the CA interface circuit by switching types of the signals, so that a selected type of signal conforms to a type of the CA module, in response to a broadcasting system of a digital television signal or the type of the connected CA module.
    • DTV模块包括CPU,解码器和CA接口电路。 解码器对从设置在母板上的解调器输入的数字电视信号执行解码处理,以将数字电视信号解码为视频信号和音频信号,并输出视频信号和音频信号。 CA接口电路通过PC卡插座连接到CA模块,并对解调器,CA模块,解码器和CPU之间通信的信号执行输入和输出处理。 CPU响应于数字电视信号的广播系统或连接的CA模块的类型,通过切换信号的类型来控制CA接口电路,使得所选类型的信号符合CA模块的类型。
