ISS 408 Integration Seamless Switcher • Introduction1-4

Features

Inputs —
Video inputs — The ISS switches among eight fully-configurable RGB, HDTV
component video, component video, S-video, and composite video inputs on
five BNC connectors per input.
Audio inputs — The ISS switches among eight balanced or unbalanced stereo or
mono audio inputs on 5-pole captive screw connectors.
Outputs —
Standard video outputs — The ISS outputs individually scaled video signals as
RGBHV or RGBS. Two sets of BNC connectors and two 15-pin HD
connectors are provided. One set of BNC connectors and one 15-pin HD
connector display the program image, and the other set of BNC connectors
and 15-pin HD connector display the preview image.
Optional DVI video output — If you install the optional DVI output card, a
single buffered DVI-D signal can be output as an additional program output
image.
For output resolutions with less than 1024 pixels horizontally, the optional
DVI program output’s true horizontal resolution is limited to 1024 pixels. For
the 1365 x 1024, 1080p, and 1080i output resolutions, the optional DVI
program output’s true horizontal resolution is limited to 1280 pixels. The DVI
card outputs all other selected resolutions normally. See the table on page 3-11.
Audio outputs — The ISS outputs the selected unamplified, line level, balanced
or unbalanced stereo or mono audio on 5-pole captive screw connectors.
Accu-RATE Frame Lock (AFL) — This patented technology exclusive to Extron
solves frame rate conversion issues experienced by video scalers. When
video input and output refresh rates differ, occasionally the two rates cross
over each other. The result is a glitch or image freeze on the display. AFL
solves this problem by locking the output frame rate to the input frame rate.
Dynamic Motion Interpolation™ (DMI™) — This video processing technique is
an advanced motion prediction and compensation method that treats motion
content and still content with different algorithms to yield high fidelity images.
3:2 pulldown detection for NTSC and 2:2 film detection for PAL video sources —
These advanced, patent pending, 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 deinterlacing 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 process, 2:2 film detection, 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 via front panel control or under RS-232 or
Ethernet remote control.
