The data from loader will bedecoded by MPEG processing and Video data and Audio data will go out.The firmware of MPEG ic is programmed to FLASH.When MPEG is boot up, the data from FLASH is dumpped to SDRAM.EEPROM will save back-up information from MPEG ic.The video data goes out in two different ways. Analog video data is going out to composite and component jack viabuffer ic(THS7374), and HDMI video data goes to HDMI jack directly.The Audio data is going out to Power AMP block. The amp block will process the audio data from MPEG ic and thesound goes throgh speakers.AUX2, AUX1, ipod, Tuner and mic data will go through ADC block in MPEG ic. The data from ADC will do the sameprocessing like SERVO.USB data from USB device and SPDIF data from optical jack also do the same things.Audio Micom(LC87C5N) is the HOST controller of the system.It will control MPEG ic, CEC micom, VFD, Touch key ic, tuner pack, and wireless module.
