Scaler IC, which is in the main SOC IC, do main video processing works of all external video input
signal from RF, CVBS, Component, PC, HDMI, USB. These input video signal through the many
kind of digital data manipulating are designed for optimal screen data and sended out as a LVDS(Low
Voltage Differential Signal) signal format for TCON(Timing Control) board at LCD panel.

Audio signal from tuner(SIF) and all external audio input signal like HDMI are passed to audio signal
processor, which is in the main SOC chipset. These input audio signal are selected by switching
block and digital processed. After data manipulating, these data send to Audio amp IC as a analog
format(PWM) or digital audio format(IIS) for speaker output.
