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.

Background Color
section
The color patch (black by default) indicates the color that will be used for the masks, and will therefore surround the
output image when it does not occupy the full output screen. Click on the
Change
… button to open the Background
Colors window. This window includes YCbCr sliders with data entry boxes, and a color preview patch. The color is
represented by an 8-bit value for each component.
•
If you have selected an illegal RGB color, it will be
flagged as “Invalid RGB” beneath the color patch, and
also within the color patch shown in the Advanced tab if
you apply it. This invalid RGB color will not be clipped by
the Gamut correction. Make sure you select a valid RGB
color if you care about Gamut errors.
•
Colors for HD and SD masks are specified independently
when the corresponding output format is selected. The
same color is used in 720p and 1080i.
5.4.4 Meta
tab
The Meta tab provides resources to deal with Metadata incorporated into the incoming signal.

Closed Caption
section
Presence:
this icon turns green in the presence of valid
incoming EIA-708-B or EIA-608-B closed captioning data as
per SMPTE-334M when an HD source is installed or when
line 21 closed captions are detected when an SD source is
installed.
Insertion:
The pull-down is used to select between
Auto
or
OFF
. Availability of these controls is affected by whether or
not Line 21 of the input SD or output SD signal has been
configured as blanking; see
SD Input/Output Config
subsection below for details.
When
Auto
is selected, closed captioning information is
processed as follows:
