Working principle analysis of the unit 1、 PAL/SECAM signal flow PAL/SECAM signal from antenna is inputted into TUNER FQD1116 which is an analog-digital-integrative model, the analog RF signal is demodulated by the TUNER, then CVBS signal and audio difference IF signal are outputted. TUNER FQD1116 is controlled by main chip MSD209(with embedded CPU)through I2C TV CVBS signal is inputted into main chip MSD209 directly to be processed bus.

4、 PC/YPbPr signal flow PC/YPbPr video signal inputted into main chip MSD209 to be processed by modules of “A/D transform, digital video process and OSD addition”, then LVDS signal is outputted to drive LCD panel. PC/YPbPr audio signal is processed by circuits of “voltage divided, impedance matching and alternating-current coupling”, then inputted into main chip MSD209 directly for acoustic process and volume control, afterwards the audio signal is inputted into left and right sound tracks of earphone amplifier...
