POWER. etc. Sub_Micom. The Micom and MPEG control each other through RXD and TXD communication.Schematic Diagram 7-1 Overall Block Diagram The main system uses the MPEG (ES8391). HDMI IC is implemented by the I2C. AUX INPUT. ADC. The Main system includes the functional blocks such as FM-TUNER. The information about the main system operation is displayed on the VFD of Front Board. MPEG (ES8391) receives RF signal from the PICK_UP and decodes Video and audio signal. Audio signal is transmitted through Analog 2V between the main body and the speaker. and is input to the AMP through ADC (CS5345). KARAOKE. The functions and DPL2 function can be controlled by the front keypad and remote control. The Power can be switched turned on or off through the Micom port. etc. CEC.
