1-3ISS 408 Integration Seamless Switcher • Introduction

Several of the output resolutions and rates include Extron’s Accu-RATE Frame
Lock™ (AFL™), a proprietary technology that locks the output frame rate to the
input rate, solving the image tearing problem that can result from different input
and output rates. The ISS 408 features HDTV 576p, 720p, 1080p, and 1080i outputs.

Figure 1-1 — Typical ISS 408 Integration Seamless Switcher application
The ISS receives and outputs audio on 5-pole captive screw connectors. The audio
can be switched with cross fading; the previous audio channel fading out and the
new audio channel fading in.
For upscaling, the ISS 408 converts the horizontal and vertical sync timing and the
number of lines of the lower-resolution video input to match the native resolution
of the display. This produces an undistorted, brighter picture than an unscaled
input would.
For downscaling, the ISS 408 accepts any computer resolution, up to 1600 x 1200,
with horizontal scan rates up to 100 kHz and vertical scan rates up to 120 Hz, and
converts the input to match the native resolution of the display.
The switcher is ideal for displaying images on projectors with limited display
resolutions, such as LCD projectors, DLP projectors, plasma projectors, and (with
an optional DVI card) a DVI display or projector.
The switcher features built-in test patterns to aid in monitor or projector setup and
evaluation.
The switcher is housed in a rack-mountable, 3U high, 17.5" wide, metal enclosure.
The ISS has an internal 100 VAC to 240 VAC, 50/60 Hz, 30 watts power supply that
provides worldwide power compatibility.
