Then, it is stored in the storage device 26 via the Internet system 24 of FIG. 3 of the air conditioner 2 of FIG. When all audio data and time stamp data are written to the storage device 26, the CPU 28 sends a video start signal to the DVD unit 1 via the Internet system 24 and the indoor power line Internet circuit. The video start signal is input to the CPU 30 via the outlet 39 in FIG. 5 of the DVD unit 1 in FIG. 1 and the power line DSL MODEM 38. The CPU 30 receives the video start signal and outputs a control signal to the video data buffer 35. The video data buffer 35 receives this control signal and outputs video data and time stamp data. The output video data is decoded by the video decoder 41 and output to the monitor 43. The time stamp data is converted into an infrared signal by the infrared transmitter 40 and transmitted to the air conditioner 2 of FIG. The infrared signal is received by an infrared remote control receiver in the air conditioner system 11 of FIG. 3, converted into time stamp data by an electric signal, and input to the CPU 28. The CPU 28 compares the time stamp data with the time stamp data stored in the storage device 26 to read out the audio data matching the time stamp data from the storage device 26 and outputs the read audio data to the audio system 12. This audio data is input to the DAC 19 through the data interface 15 and the DSP 16 of the audio system 12 shown in FIG. 4, where it is converted into an analog signal and supplied to the speakers 5 and 6 through the amplifier 20. As a result, musical tones synchronized with the video data are generated from the speakers 5 and 6. As described above, according to the above embodiment, in order to synchronize the reproduction of the video data in the DVD unit 1 of FIG. 1 and the reproduction of the audio data in the air conditioner 2, the time stamp data from the DVD unit 1 to the air conditioner 2 It is the feature that it is transferred by. As described above, according to the present invention, the air conditioner is provided with the speaker and the 10-05-2019 4 circuit for driving the speaker, and audio data is transmitted to the air conditioner via the power line Internet to drive the speaker.
