6.4 Analog Output Fine (Horizontal Timing)
Further adjusts the horizontal output timing of the analog output (only) in finer
increments than 6.2 (above)—in this case by sub-pixels. Each adjustment of this
control, from 0 to 127 adjusts the analog output timing by 1/128th of a pixel. Like 6.2,
horizontal output timing is adjusted with reference to the Ref video selected.
7.1 Sidebar Keyer
This parameter turns the Sidebar Keyer
On
or
Off
, and selects the source for sidebar
video. Sidebar keying is useful when upconverting standard definition video to HD in
4:3 Pillar mode, as the sidebar key replaces the black on the sides of the 4:3 picture.
A switch controlled by parameter 7.1 selects whether normal video or the sidebar key
gets routed to the outputs. If the Sidebar Keyer is On the key gets sent to the outputs;
if the keyer is Off, normal video goes to the outputs.
When the Sidebar Keyer is turned
On
, a standard definition signal from the selected
main input source (parameter 2.1) is upconverted to HD. The keyer then uses this
upconverted video to fill the center of the 4:3 image and adds HD sidebars from the
source selected here in parameter 7.1.
The input selected here (7.1) for the Sidebar must be an HD signal, and it must be the
same format as that selected for parameter
1.1 Output Format
.
The sidebar width created by the keyer is specified in parameter 7.2.
Notes:
1.
It is normal for SD sources used for the sidebar fill to sometimes have
asymmetrical edges (if SD video isn’t cropped to “real video”). This can be seen
in some cases where digital video was digitized from analog.
2.
The
Composite
and
S-Video
inputs are not available as the sidebar source since
they only support SD and the sidebars must be HD to match the center video.
The
Component
input may be used as a sidebar input source for 7.1—but only if the
main input selected by 2.1 is not
Composite
or
S-Video
. (There is only one A/D
converter in the FS1, and it cannot be used for both inputs simultaneously.)
