In the embodiment of the present invention, the television tuner device 3 (8) is coupled to a vehicle-mounted display 100, and the main body 41 of the audio system 4A is sensed by the FM modulation transmission method, and then the sound is played by the speaker 42. The TV tuner 3GG includes a hard-to-vehicle type display, a demodulator 3, and a modulated signal transmission module 2 coupled to the demodulator 31. The demodulator 31 is configured to receive a television signal. 3 〇 1 and demodulated into a television display A No. 401 to the vehicle-mounted display j 〇〇 playback; in addition, the television tuning device 300 further includes a video input interface 32 coupled to the selection unit, and the audio input interface 32 is used To receive an input source including a VCD, a DVD, a CCD, a game machine (Game), a global positioning system (0), or an Mp3 audio and video signal, and capture the video signal 302 to convert it into an image display signal 4〇2 The vehicle-mounted display device 100 is played; thereby, the vehicle-mounted display device 1 can play the television display signal 401 and the image display signal 4〇2. As shown in FIG. 1 and FIG. 2, the demodulator 31 of the television tuner device 3 is received by the television receiver 301 and demodulated, and then played by the vehicle-mounted display device 1; and the modulated signal transmission module 2 has a The selection unit 21 (AV Switch) is connected to the audio processor 22 (Sound Processor), a modulated audio transmitter 23 (FM Transmitter) and a master selection unit 21, and audio processing. The device 22 and the modulated signal transmitter 23 signal processing > Microcontroller 24 (Micro Controller). The 'selection unit 21 is for receiving an external input signal. In the preferred embodiment, the source of the external input signal is the television transmitted by the demodulator 31. 1, or the video signal 3 〇 2 transmitted by the video input interface 32, ^ select ^ 21 and convert it into - sound as simple as the image display signal for output; and the audio processor 22 receives the sound signal 3 〇 3 and gives 2 large; the modulated signal transmitter 23 is used to convert the amplified audio signal 3〇3 ... to the modulation signal 304'. Thereby the microcontroller 24 controls the selection unit 21 :: the audio signal 303 is transmitted to the audio processor 22 processing, and the modulation signal 3〇3 is modulated into a modulation signal 3〇4 by the modulation signal, and the host 41 of the sound system lion on the vehicle can sense the modulation signal 304 and demodulate it. And the sound is played by the speaker 42. The two 'modulation signal transmission module 2 further includes __microcontroller 己 already recalls early 7C 25 ' and the microcontroller 24 has direct screen display (〇SD) power month b /5 recalled single % 25 storage There are parameters for the microcontroller 24 to make adjustments on the direct display of the on-board display g.
