Product Overview
Description
The IN1404 is a full-featured video and RGB scaler that combines digital video decoding, advanced
video scaling and a 4-input A/V switcher into a single product. The IN1404 uses sophisticated digital
video decoding and scaling technology to convert a composite video, S-video, interlaced or
progressive component video signal and RGB signals (at various scan rates and resolutions) to
standard VGA and HDTV resolutions and refresh rates.
Features
Superb Video Scaling Technology
— Employing sophisticated video de-interlacing, scaling and
filtering techniques, the IN1404 offers an output signal with 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 IN1404 employs high bandwidth digital signal processing, high
speed digital to analog conversion, and sophisticated 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 IN1404 provides
accurate video decoding of composite video and S-video signals in the NTSC, PAL, SECAM and NTSC
4.43 video standards. The video decoder employs an advanced 3-line adaptive comb filter for
composite video signals and greatly reduces cross-color interference and hanging dots, while
maintaining maximum image bandwidth and detail.
Advanced RGB Scaling
— The IN1404
also provides superb upscaling and refresh rate changing for
640 x 480, 800 x 600 and 1024 x 768 resolution RGB video signals, making it an excellent companion for
LCD and DLP display devices that have marginal, on-board video scaling capability. The unit can
accept standard and non-standard RGBHV, RGBS and RGsB signals at horizontal scan rates from
15 KHz - 60 KHz and scale them up to the desired resolution and refresh rate.
Selectable Output Resolution
— The IN1404
offers a wide range of output resolutions to match the
optimum or native resolution of virtually any display device. The IN1404 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 IN1404
output vertical refresh rate is adjustable from 60 Hz to 120 Hz.
By converting PAL (50 Hz) and NTSC (60 Hz) input signals to higher, more ergonomic refresh rates,
the scaler makes it possible to display a remarkably solid, flicker-free image when using CRT monitors
and projectors. The chart on page 22 indicates the available output resolutions and refresh rates.
4-input Video / Audio Switcher
— The IN1404
provides multiple inputs and flexible switching
capability to accommodate a variety of applications. Inputs 1 and 2 can each accept a composite video
or S-video signal. Inputs 3 and 4 accept composite video, S-video, component video, progressive
component video, RGB, RGBS, or RGBHV signals. Inputs 3 and 4 can also be set for passive mode in
which they provide no decoding, scaling or refresh rate changing. Stereo audio-follow-video
switching is provided for all four inputs.
Digital Freeze Frame
— Provides a high quality still image for applications that require close
examination of a specific video frame. Freeze frame operates for video signals and RGB signals that
are being routed through the RGB scaling circuitry. Freeze is not available when the input is
configured for RGB passive.
Video Blank button
— Located adjacent to the
Input Select
buttons, the
BLANK
button allows the
video image to be suppressed. When blank is engaged, the output 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 once again displayed. The blank feature can
also be engaged or disengaged using an RS-232 serial command. Video blanking is not available when
the input is configured for RGB passive.
