The route of DTV input
DTV signal demodulated by the tuner then the demodulating signal is divided into two parts, video
and audio signal. The video signal is decoding by
MT5112
. The decoded signal, as the format of
MPEG4, is transmitted to and processed by MT5372. Also, MT5372 generates a LVDS for display
device. The audio signal is transmitted in the route named FAT-IN. The FAT-IN 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.

There are 7 keys to control and to select the function of VX37. Also, there is a LED back light under
the logo “VIZIO” to indicate the status of operation (Orange => STANDBY, White => ON). They are
