Inverse 3:2 pulldown detection for NTSC for film-originated video material —
This advanced film mode processing feature helps 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 IN1404XT’s advanced film mode processing recognizes signals
that originated from film. The scaler 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.
Quad-standard decoding — The IN1404XT’s video decoder provides accurate
video decoding of composite video and S-video in the NTSC, PAL, SECAM,
and NTSC 4.43 standards. The advanced 3-line adaptive comb filter that
decodes composite video reduces cross-color interference and hanging dots
while maintaining maximum image bandwidth and detail.
Seamless Switching - Input 4, when configured as a passive (unscaled) input,
serves as a time reference for seamless switching. The IN1404XT provides a
seamless transition between scaled inputs on 1, 2, or 3 (RGB, component,
S-video, or composite video) and the passive RGB video on input 4.
Picture controls — A wide variety of picture controls are available for fine picture
adjustments:
• Position
• Size
• Aspect ratio
• Hue
• Saturation
• Brightness and contrast
• Gamma
• Horizontal tracking
• Sharpness
Once these adjustments are made, the settings are stored in non-volatile
memory and automatically recalled when the same input source is selected
again.
Advanced image adjustment controls — A wide variety of picture controls are
available to optimize the image when the scaler is used with proprietary and
non-standard input signals.
Once these adjustments are made, the settings are stored in non-volatile
memory and automatically recalled when the same input source is selected
again.
Blue screen mode — The scaler can be set to output a blue video field, to help
installers calibrate the monitor or projector. Blue screen is always available,
whether or not an input is present or properly adjusted.
On screen menus - The scaler puts its menu displays on the output video stream,
for display by the output monitors or projectors. The menu system provides
easy control of video adjustments including hue, color, contrast, brightness,
