About the Scaler
The Extron IN1404XT is a video scaler that incorporates a four-input video and stereo audio switcher (figure 1-1). The scaler accepts NTSC/PAL/SECAM/NTSC
4.43S-video (Y/C) and composite video inputs and stereo audio inputs on all four inputs and high resolution RGB video and interlaced or progressive component (YUV) video on inputs 3 and 4. The IN1404XT scales the inputs to standard VGA and HDTV resolutions and refresh rates and outputs RGBHV, RGBS, or RGsB video and stereo audio. Input 4 can also be set to a passive mode that provides no decoding, scaling or change of refresh rate and can be set as a timing reference for seamless switching. The scaler can seamlessly switch to and from passive input 4 to bring professionalism and style to boardrooms or other system integration environments. Seamless switching allows switching between sources without a loss of sync. The scalers’ scaling capabilities permit differing video formats on each input to be displayed by a common projector.
Each video input is individually configurable to allow for different video formats. The scaler allows analog RGBHV, RGBS, and RGsB video, component video, S-video, and composite video signals to be displayed on a device with a fixed resolution and aspect ratio, such as an liquid crystal display (LCD) projector, digital light processor (DLP) projector, or plasma display.
The scaler inputs high-resolution RGBHV/RGBS/RGsB video, and component video on two sets of five BNC connectors. The scaler inputs S-video on 4-pin mini DIN connectors (inputs 1 and 2) and on two sets of two BNC connectors (inputs 3 and 4). The scaler inputs four composite video inputs on BNC connectors. The scaler inputs audio on RCA connectors.
The IN1404XT scales the input up to any of 48 output resolutions and rates and outputs the scaled video, as two identical RGBHV, RGBS, or RGsB video outputs, on five BNCs and a 15HD connector. Additionally, the scaler acts as a twisted pair (TP) transmitter, outputting the identical video signal on an RJ-45 connector for connection to an optional Extron VTR001CM TP receiver. (See TP transmission, in this chapter, for more information about the RJ-45 output.) With all three video outputs active at all times, the IN1404XT can drive three video displays simultaneously, with no need for a distribution amplifier.
There is one stereo audio output, on left and right RCA connectors.
For upscaling, the IN1404XT 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.
The scaler is housed in a rack-mountable, 1U high, 17.5” wide metal enclosure. With the included mounting ears, the scaler is rack-mountable. The scaler has an internal 100VAC to 240VAC, 50/60 Hz, 25 watts auto-switchable power supply that provides worldwide power compatibility.
