<Main Board>
Formats of input sources include RF, CVBS, S-VIDEO,COMPONENT,SCART,PC and DVI.
GM1601H, a SCALER IC, has built-in TMDS that enables to process DVI signals without an additional IC
and includes HDCP (High Bandwidth Digital Content Protection).
This is a neighboring circuit component IC that consists of a DDR memory and a 2M flash memory chips.
It processes various signals including RF, AV, S-Video and Component before transferring them through
CM-LVDS, a picture quality IC, to the panel.
Signals from RF, AV, S-Video and Component go through VCTi, a video processor IC, into the scaler IC
before processed in the same way above.
RF and AV signals are transferred to and from UPD64084 IC, a 3D Comb Filter, which separates the color
signals (C) from the luminance ones (Y) for better picture quality while Component signals go through
MST9886, an ADC, to DE-INTERLACE and finally into the scaler IC.
Sound signals pass through so-called Lip Sync IC, which compensates for the problem of separate transfer
of video and audio signals in broadcasting.
VCTi IC processes the video and sound signals at the same time.
It has BBE and DolbyVirtual sound features that amplify the sound signals using Amp TPA3002.
It can receive all signals including from NTSC, PAL and SECAM with only one tuner. In addition, it supports
FM radio reception.

The video signal experiences a time delay when processed by the Deinterlacing / Scaling
module. Due to this problem, the audio plays before the corresponding video appears. To
resolve this problem, an audio delay is introduced by the audio delay module that consists
of an AD converter, which converts the analog audio signal into digital, a delay module, and
a DA converter, which converts the digital signals into analog.
