The Block Processing Video Signal
1. Component, PC and CVBS signal like AV are inputted to Scaler-IC (MT8226(IC5105)) directly.

2. HDMI signal is inputted to switch-IC, TMDS351 to select just 1-HDMI input in 3-HDMI input.
(But HDMI3 (Side) inputted to Scaler-IC directly), And then Selcted HDMI signal is inputted to Scaler-IC.

3. Scaler-IC converts video signal to 12bit of LVDS Signal, standard format to run a LCD panel.

4. FBE3-IC receives this LVDS signals and processing it to enhamce picture quality.
And then final 12bit of LVDS Signal is outputted.

The Block Processing Sound Signal
1. Sound signals of RF(SIF), HDMI, Component, DVI, PC and AV input are inputted to
Sound-IC (MT8291 (IC2102)).
DTV_AUDIO signal is also inputted for MP3 connected to wiselink.
MT8291(IC2102) processes these signal and outputs 12C signal to digital AMP-IC (NTP3100 (IC2104)).
And signals for headphone and Monitor-out are outputted.

2. NTP-3100 IC outputs an analog sound signal to run Speakers.
