Inverse 3:2 pulldown detection for NTSC video sources and 2:2 film detection for PAL video sources — 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 IN1508’s advanced film mode processing recognizes signals that originated from film. The switcher 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.

A similar process is used for PAL film-source video.

Quad-standard decoding — The IN1508’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.

Picture controls — A wide variety of picture controls are available for fine picture adjustments:

•Position

•Size

•Brightness and contrast

•Color and tint

•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.

On-screen menus — The switcher puts its menu displays on the output video stream, for display by the output monitor or projector. The menu system provides easy control of video adjustments. The on-screen menus also make it easy to verify and adjust advanced settings such as output signal resolution, refresh rate, sync format, and the reset to factory defaults function.

Audio follow — When an input is selected on the front panel, the audio input follows its corresponding video input signal (audio follow). Under RS-232 control, the audio input can be switched to follow either the main window selection or the PIP window selection.

Operational flexibility — Operations such as input and scaling selection and picture controls can be performed on the front panel or over the RS-232 link. The RS-232 links allow remote control via a PC or control system.

•Front panel control — The switcher’s front panel controller and on- screen menus support individual input selection, resolution selection, volume control, and complete configuration of the switcher.

•Infrared remote control — The switcher includes an Infrared (IR) remote control that duplicates all of the front panel functionality and some RS-232 functionality.

•Simple Instruction Set (SIS) commands — The remote control protocol uses Extron’s SIS commands for easy programming and operation.
