3:2 pulldown detection for NTSC and 2:2 film detection for PAL video sources —
These advanced film mode processing features help maximize image detail
and sharpness for video sources that originated from film. When film is
converted to NTSC video, the film frame rate has to be matched to the video
frame rate in a process called 3:2 pulldown. Jaggies and other image artifacts
can result if conventional de-interlacing techniques are used on film-source
video. The ISS's advanced film mode processing recognizes signals that
originated from film. The ISS then applies video processing algorithms
that optimize the conversion of video that was made with the 3:2 pulldown
process. This results in richly detailed images with sharply defined lines.
A similar 2:2 pulldown process is used for PAL film-source video.
Audio follow and breakaway — Audio switching can follow its corresponding
video input signal or it can be broken away from the video input. Audio
breakaway switching can be done under RS-232/RS-422 or Ethernet remote
control.
Audio gain/attenuation — Users can set the input level of audio gain or
attenuation (-18 dB to +24 dB) via the RS-232/RS-422 or Ethernet link, or from
the front panel. Individual input audio levels can be adjusted so there are no
noticeable volume differences between sources.
Audio cross-fading — A transition technique that is applied during the switches.
It lowers the audio level of the switched out source while simultaneously
raising the audio level of the activated source.
Logos — The ISS can display one or two logos on the preview and program
outputs.
Image (logo) save and recall — The ISS can capture an input image and save it for
use as a logo.
Picture-in-picture and title — The ISS can display the preview input on top of the
program output as either a picture-in-picture (PIP) window or a title.
LAN port — Supports connection to an Ethernet LAN so that the switcher can be
accessed and operated anywhere in the world from a computer running a
standard Internet browser.
Quad-standard video decoder — The switcher uses a digital, four-line adaptive
comb filter that can decode NTSC 3.58, NTSC 4.43, PAL, and SECAM signals.
Transitions — Control the type of switch that occurs between the preview and
program outputs. The Cut button creates an instant switch between the
preview and program outputs. The Wipe and Dissolve buttons switch with a
masking effect.
Test patterns — The switcher features built-in test patterns to aid in monitor or
projector setup and evaluation.
Blue mode — The switcher can be set to output the blue video signal only, to help
installers calibrate the monitor or projector.

planes to blank the screen while the scaler locks to the new sync, so that
a noise-filled scramble is not shown on the monitor during the transition.
The time delay between the RGB and sync signals is user adjustable up to
5 seconds under front panel, SIS, and program control.
Auto memories — The six inputs support 16 auto-recall memories each, based on
the incoming frequency. Information on sizing, centering, detail, contrast,
and brightness is saved. Auto memories can be turned off under advanced
configuration.
