1-1 Overall Block Diagram
The Main System uses the MPEG(ES 8381), the Up_scaler(FLI2301) and the Tx(SiI9030) of HDMI. The Main System
consists of major circuit blocks such as HDMI, POWER, CEC, Front, Karaoke, etc. The Main System includes the
functional blocks such as FM-Tuner, Input, ADC, Sub_Micom IC, etc.
Display is connected with VFD.
Audio signal is transmitted through Analog 2V between the main body and the sub woofer and is input to the AMP
through ADC(AK5384).
First, MPEG(ES8381) receives RF signal from the PICK_UP and decodes video and audio signal.
HDMI IC is implemented by the I2C. The Micom and MPEG control each other through RXD and TXD communication.
The Power supplies voltages for each component using the SMPS. The Power can be switched turned on or off through
the Micom port.
The functions can be controlled by the Touch Key and the DPL2 functions can be controlled with the remote control.
