Input Formats
This is the second thing to do when setting up your SE-800 for use: select the
input format for each channel you’ll be using. These controls are active as soon
as you push the upper channel select button. They become inactive when you
have cycled through all 4 channels or when you press a button in any other
control except the Color Processor.
Select a channel and it is temporarily shown on the video output, allowing you to
select the proper video format and use the Color Processor (see below).
The lower button makes the format selection and lights an LED to indicate the
choice.
DV=IEEE 1394 digital video (a.k.a. Firewire, iLink)
V=composite video
S=S-video (Y/C) (S-VHS, Hi8, etc.)
YUV=analog component video (Betacam, DVCPro, DVCam, etc.)
Settings made in this section are “remembered” by the SE-800 after you power down the unit. In other words,
these settings remain in effect until they are changed or the Reset All button is pressed (see
Color
Processor
below).

Tech note
: Transcoding is the act of changing video from one format to another,
for example, from composite video to S-video. The SE-800 has been designed to
perform transcoding, as well as digital to analog and analog to digital conversions,
as part of its standard operating procedure. Select a video source at the Main
Source Input bus, and it will be available at the Main Output in all formats, digital
and analog, simultaneously. With the exception of analog component (YUV) and S-video (Y/C): only one of
these output formats can be available at a time.
Color Processor
The Color Processor is active only when the Input Format section is
active. Its controls work on the channel selected by the upper button in
the Input Format section, which is temporarily displayed at the Video
Output. These controls are like picture controls on a video monitor or
the proc amp (processing amplifier) controls on a time base corrector.
In fact, they
are
the proc amp controls of one of the SE-800’s 2 internal
TBCs.
On the left side of this section is a column of 9 LEDs, 4 red ones above and below the green LED marked
“U.” These LEDs are lit, and this section’s controls are engaged, when any of the 4 pairs of control buttons
