Anti-Dither (1/2/off) Anti-Dithering Mode is design to work with ATI graphic cards that provide dithering output.
Dithering output is used to make coloring looks better than it's original color depth. It uses visual
transient to create a half-tone effect. However, this presents great difficulty for Video Compression
to maintain low bandwidth even if the source display seems static.
Currently, we only see Dithering Output with ATI graphic cards.
To resolve this issue, AST1500 provides Anti-dithering for 1 bit, 2 bit, or off.
If the source content does not generate dithering output and this feature is turn on. It will create a
blocking effect because Video Engine are unable to detect pixel changes. User can avoid this
issue by turning this feature to off.
