Selenio X100
Installation and Operation Manual
37
Note : The Selenio X100 accepts PAL-M composite video that complies to ITU-R BT.470-6
standard (with burst amplitude of 300mV), as well as a variant that is used commonly in
Brazil (with burst amplitude of 287mV). Ensure that you select the correct PAL-M standard
for detection. An incorrect standard setting will distort the color level of the video. To select
the PAL-M standard for detection, follow
Misc > Others >PAL-M Standard , and then
select either Brazil (default) or ITU-BT470-6 .
Analog Output Control (Video)
When the X100OPT-AVIO softkey is installed, the X100 supports the following types of
analog video outputs:

Composite (NTSC) only for 59Hz output formats

Composite (PAL-B) only for 50Hz output formats

Composite (PAL-M) only for 59Hz output formats

CAV (RGB)

CAV (YPrPb-SMPTE)

CAV (YPrPb-Betacam)
To provide analog video output, you must select a value at Video > Analog Output
Control > A to D 1/2 > Analog Output Type . To enable pedestal, set the Analog Output
Pedestal parameter to Yes . You may also enable Super Black encoding by selecting Super
Black > Enable . Otherwise, any luma level below black will be clamped to black at the
output. The X100 supports fine phase adjustment for composite video output. You may
adjust the subcarrier phase over a full subcarrier cycle by setting
Fine Phase Enable to Yes,
and changing the F ine Phase Delay and Composite Output Pixel Delay parameters.
Note: When Fine Phase is enabled, the output and reference composite standards must
match, to avoid output video distortion
Video ProcAmp and Color Corrector
This control block includes parameters for the video proc amp, hard clip control, legalizer.
and color corrector.
Proc Amp
These parameters make it possible to modify the black level, luma gain, chroma gain, and
hue.
Clip Control
Y, composite, and GBR levels are adjustable using the parameters in the Clip Control
group. Y levels are enabled and set using White and Black clipping controls. Using the
following composite video clipping parameters, you can limit the values of luma, Cb and Cr
before the signal is converted by the analog video encoder.
