  In terms of AUDIO.

  In Digital In mode, SPDIF signal goes into MPEG (ES8391).

  In AUX ½, TUNER mode, Analog Audio signal goes into A/DC (CS5345) and converted I2S signal and goes to

MPEG (ES8391).

  MPEG (ES8391) outputs I2S and it goes into DSP (CS48540) and Equalized and it goes into PWM (PS9829B).

  The output signal of PWM (PS9829B) goes into AMP (TAS5142) and it is SPEAKER Output.

  In terms of VIDEO.

  DVD Loader outputs RF signal and MPEG (ES8391) get RF signal and Decoded.

  MPEG (ES8391) outputs Analog Video signal (Composite, Component Video) and outputs 32bits Digital Video signal to

HDMI TX (ES7108) and it converted TMDS signal and it is HDMI video Output.
