and the color of the mask.

MPEG Preprocessor Mode:
This control changes the functionality of the detail enhancer. When MPEG
preprocessor is activated (‘
ON’
), the adaptive detail enhancer will use a psycho-visual model to increase the
level of details and the sharpness of edges without adding high frequency content that may be difficult to
encode at a lower bit rate on a downstream MPEG encoder.
When the MPEG preprocessor is deactivated (
OFF
), the adaptive detail enhancer will increase the details
and the sharpness of edges without causing ringing on the HD output. In this mode (‘
OFF’
), high frequency
content is added to the HD video output to improve graphic contents and characters. This setting is very
useful for upconverted material in character generation (CG) applications.
Detail Enhancer:
Enhances the perceived sharpness of fine detail and edges. A single control adjusts both
Horizontal and Vertical detail enhancement: a slider and a data reporting/entry box allow the user to select a
value ranging from
0
(no enhancement) to
7
(maximum enhancement). The default value varies according to
the processing mode: 4 for SD to HD mode and 0 for HD to HD mode.

Separate controls are provided for Horizontal and Vertical detail enhancement:
Horiz. Detail Enhancer Mode:
this pull-down box controls the type of horizontal detail enhancement, which
may improve sharpness of textures and contours.
•
High Freq
boosts high frequencies of the input signal
•
Medium Freq
boosts medium frequencies of the input signal
Horz. Detail Enhancer
: a slider and a data reporting/entry box allow the user to select a value in the range 0
(no enhancement) to 7 (maximum enhancement).The default value is 1 for HD to SD mode, and 0 for SD to
