a) RF Signal
Digital intermediate frequency and simulation intermediate frequency are processed by Tuner (U42) from RF
Signal. Transport Stream is demodulated directly by main IC from Digital intermediate frequency then enter
PCMCIA card to decipher later return the main IC. The simulation intermediate signal that has passed
amplification and surface acoustic wave filter to get intermediate frequency enters the main IC. After processed
by main IC, next the video signal is processed by SCALER output LVDS signal.to panel . The audio signal is
processed and the Audio amplified to the Speakers.
b). AV Signal
The video signal of AV and YPbPr share the same Terminal of XS13，then enter U46.
