Vert Detail Enhancer Mode:
this pull-down box controls the type of vertical 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
Vert. Detail Enhancer:
a slider and a data reporting/entry box allow the user to select a value in the range -8
(some softening) to +7 (maximum enhancement). Set the value to 0 for no enhancement. The default value
is 1 for HD to SD mode, and 0 for SD to SD mode
HD to SD Output Resolution
Select the output image width (in pixels) when the SD output is down-converted from HD. Select between
720 pixels (default) and 704 pixels.
•
Normal SD image width is 720 pixels. In ATSC applications MPEG encoders will crop to 704 pixels
for encoding and the setup box will stretch back to 720 pixels creating 2% anamorphism. To
compensate for this problem, the user may select 704 pixels using the
H Size
pull-down. This will
compress the down-converted image to 704 pixels instead of 720 pixels. When stretched back to
720 pixels by the setup box, the anamorphism will be eliminated. This functionality is only available
for HD-to-SD conversions. The factory default for this parameter is 720 pixels. The value selected
here appears in the pull-down beneath the Output Screen at the top of the panel when an HD-to-SD
down-conversion is selected.
Background color
sub-section, HD and SD output
This 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.
The
Meta
tab
The Meta tab provides resources to deal with Metadata incorporated into the incoming signal.
Closed Caption
sub-section
Presence:
this icon turns green in the presence of incoming EIA-708-B or EIA-608-B closed captioning data
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:
SD to HD Upconversion:
The closed-captioning information from line 21 field 1 and the V-chip information from line 21 field 2 of the
incoming 525-line signal may be inserted as ancillary packets required for FCC compliance. NTSC and DTV
