Product Overview

Description

The IN1403 is a full featured video scaler that combines digital v ideo decoding, advanced video
scaling/line multiplication and a 4-input A/V switcher into a single product.

Features

Superb Video Scaling Technology — Employing sophisticated video de-interlacing, scaling and
filtering techniques, the IN1403 offers an output signal wi th outstanding image detail and enhanced
brightness that is entirely free of visible scan lines. The scaler automatically senses the origin of the
video source material and selects the optimum motion compensation formula to eliminate unwanted
artifacts in the output image. The IN1403 employs high bandwidt h digital signal processing and high
speed digital to analog conversion, combined with effecti ve filtering and sharpness circuitry to
maintain and enhance image detail, even at the highest output resolutions.
Advanced Quad Standard Video Decoding — A high quality video decoder in the IN1403 provides
accurate video decoding of composite video and S-video signals in the NTSC, PA L, SECAM and NTSC
4.43 video standards. The video decoder employs an advanced 3-line a daptive comb filter for
composite video signals and greatly reduces cross-color inte rference and hanging dots, while
maintaining maximum image bandwidth and detail.
Pick the Perfect Resolution — The IN1403 offers a wide range of output resolutions t o match the
optimum or native resolution of virtually any display device. The IN1403 provides a progressive scan
output signal at standard resolutions and refresh rates, ensuring optimal compatibility and
exceptional image quality with a wide range of CRT, LCD, DMD, ILA, D-ILA, and plasma display
devices.
Selectable Refresh Rate — The IN1403 output vertical refresh rate is adjustable from 60 Hz to 120 Hz
By converting PAL (25 Hz) and NTSC (30 Hz) input signals to higher, more ergonomic refresh rates,
the IN1403 makes it possible to display a remarkably soli d, flicker-free image when using CRT
monitors and projectors. The chart on page 18 indicates the output resolutions and refresh rates
available on the IN1403.
4-Input Video/Audio Switcher — The IN1403 provides multiple inputs and flexible switching
capability to accommodate a variety of applications. Inputs 1, 2, and 3 can each accept a composite
video or S-video signal. Input 4 is a 15-pin HD VGA pass-through connector for a computer video
signal (passive, no scaling). Stereo audio-follow-video switching is provided fo r all four inputs.
Memory — The IN1403 can recall previously stored settings wi th the push of a single button. All
audio, video, input and output settings, for each input and each output mode, are stored internally (in
memory). Once optimized, all adjustments are automatically recalled every time an input is selected.
Digital Freeze Frame — Provides a high quality still image, useful for applications that require close
examination of a specific video frame. Freeze Frame can be enabled/disabled using the front panel
FREEZE FRAME button or an RS-232 serial command. Freeze is functional for Inputs 1, 2, and 3. It
has no effect on Input 4, which is a passive input.
Video Blank button — Located adjacent to the input selector buttons, the BLANK button allows the
video image to be suppressed. When blank is engaged, the ou tput signals go to black but the sync
signals continue, ensuring that the data display device retains sync lock. When the BLANK button is
pressed a second time, the previously selected input is on ce again displayed. The blank feature can
also be engaged or disengaged using the RS-232 serial command. Vide o blank is functional for Inputs
1, 2, and 3. It has no effect on Input 4, which is a passive i nput.
On Screen Menus — Provides easy control over video adjustments including hue, color, contrast,
brightness, gamma, sharpness, image size, image position, and edge blanking. Unique image sett ings
can be optimized and stored for each input. Each time an input is selected, all image settings stored
for that input are automatically recalled. The on-screen me nus also make it easy to verify and adjust
advanced settings such as output signal resolution, refresh rate , sync format, RS-232 control options,
and reset to factory default.
