The route of D-SUB 15pin input
An RGB (analog) signal is inputted the D-SUB 15pin to the
MT5372
which transfers it to a digital
signal by the A/D converter. Then MT5372 generates a Low Voltage Differential Signal (LVDS) for
display device.
The route of HDMI CON input
A HDMI (digital) signal is inputted the HDMI 1&2 CON to the
PI3HDMI412FT
switch. The passing
signal is processed with the MT5372. Then MT5372 generates a LVDS for display device.
The route of HDTV & Component input
HDTV & Component signal is inputted to the MT5372. After processing, MT5372 generates a
LVDS for display device. The audio signal is inputted
WM8776
. After processing, WM8776
transmits the signal to
TDA8946J
, an audio amplifier. Then, the amplified signal is the output audio
signal.
The route of Video 1,2,3 & S-Video input
The Video 1,2 and S-Video signal is inputted to the MT5372.After processing, MT5372 generates a
LVDS for display device. The audio signal is inputted WM8776. After processing, WM8776
transmits the signal to TDA8946J, an audio amplifier. Then, the amplified signal is the output audio
signal.
The route of TV input
TV signal is demodulated by the tuner then the demodulating signal is divided into two parts, video
and audio signal. The video signal is processed by MT5372 then MT5372 generates a LVDS for
display device. The audio signal is transmitted in the route named SIF. The SIF signal is
demodulated and decoded by MT5372. The decoded analog signal is transferred into I2S, which is
digital signal, by MT5372. The I2S signal is inputted and transferred into analog signal by WM8776.
After processing, WM8776 transmits the signal to TDA8946J, an audio amplifier. Then, the
amplified signal is the output audio signal.
