Use the
Input Number
pushknob to select the physical input number.
This number corresponds with the input number on the Signal Chassis,
not the crosspoint button assignment. Even numbered inputs have a
Master/Slave
pushknob that the odd numbered inputs do not have, as
described later.
The Format pushknob sets the analog signal type for the selected input
with the Input Number pushknob. All of the selections listed below
appear for either input of the Dual Component Analog Input module;
however, only the video selections appear for the video (odd numbered)
input of the Component Video + Key Input module, while only the key
selections appear for the key (even numbered) input of that module.
SMPTE/EBU
– The SMPTE/EBU N10 700mV color difference
standard, containing Y, R-Y, and B-Y components with black level at
0mV. This format is compatible with all 625-line standard and MII

VTRs and some 625-line Betacam

and Betacam

SP VTRs that have
been modified for EBU levels.
50Hz Beta – Y/R-Y/B-Y color difference signals from 625-line
Betacam

or Betacam

SP VTRs.
60Hz Beta wSU – NTSC-related Y/R-Y/B-Y with 7.5 IRE (54mV)
black level (i.e., with setup). This format is compatible with all 525-line
Betacam

and Betacam

SP VTRs outside of Japan.
60Hz Beta woSU – NTSC-related Y/R-Y/B-Y with 0 IRE (0mV) black
level (i.e., without setup). This format is compatible only with
Japan-market 525-line Betacam

and Betacam

SP VTRs.
60Hz MII
– Y/R-Y/B-Y with 7.5 IRE (53mV) black level. This format
is used on 525-line standard MII

VTRs. 625-line MII

format VTRs
use the SMPTE/EBU format.
SMPTE/EBU GBR – The SMPTE/EBU 700mV standard containing red,
green, and blue components with no setup (0mV black level).
SMPTE/EBU KEY
– A black and white (high contrast) signal used as a
dedicated key source at SMPTE/EBU levels (peak white = 700mV). This
format internally copies the luminance value to the Cb and Cr channels to
provide a key signal for the chrominance samples of the fill signal. Use this
setting if the input is a dedicated monochrome key signal with no chroma.
NTSC KEY wSU – A black and white (high contrast) signal with 7.5 IRE
(54mV) black level (i.e., with setup), used as a dedicated key source at
NTSC levels (peak white = 100 IRE or 714mV). This format internally
copies the luminance value to the Cb and Cr channels to provide a key
signal for the chrominance samples of the fill signal. Use this setting if the
input is a dedicated monochrome key signal with setup and no chroma.
The Component Key Input module also contains a mode that
converts high resolution analog RGB or Y/R-Y/B-Y to a component
