This research is about receiving and processing Korean and Japanese audio multi broadcast signal receiving device,A tuner (1) and receiving a frequency exchange signal brought by a tuning voltage;A 4.72mhz pipeline signal is detected from the signal received by the dispatcher (1), and the first detection unit (2) and of the first detection signal are output;4.5mhz pipeline signal is detected from the signal received by the dispatcher (1), and the second detector (3) and the second detection signal are output;The output is based on the tuning voltage controlled by the user,According to the recognition of the first and second detection signals, the control units (4) and (2) outputting the first and second driving signals are selected;According to the first driving signal, the signal received by the electroaudio (1) is processed in the Korean audio multicasting mode, which is divided into the first multiprocessing units (6) and (6) of the left and right sides (SP1, SP2);According to the second driving signal, the signal received by the above tuner (1) is driven and processed in the Japanese audio multicasting mode, equipped with a second multiprocessing unit (7) permitted by the left and right loudspeakers (SP1, SP2).;That is to say, as a TV, this research can automatically process the Korean and Japanese audio multi broadcast signals, which has the effect of improving the convenience of TV use.
