Video Processing

Both audio and video signals are processed by the MT5382
audio/video processor. Refer to diagram B4 for details.

In basic sets (sets without DNM/AmbiLight), the video signal is
fed directly to the panel via an LVDS connector. Refer to figure
“Video processing - basic sets” for details.

Figure 9-5 Video processing - basic sets

In sets which support DNM/AmbiLight, the signal coming from
the MT5382 audio/video processor is fed to the MT8280 motion
engine with double frame rate output (120 Hz). Refer to

diagram B5R and figure “Video processing - DNM+AmbiLight
using MT8280 Motion Engine)” for details.
