About the VSC 150

Extron’s VSC 150 is a high resolution computer-to-video scan converter with all digital controls. The VSC 150 converts a computer video signal into two display outputs

–composite video and one of the following:

• S-video,

• component video, or

• RGB video (RGBHV or RGBS)

for simultaneous scan-converted output on two separate devices. This allows the video from a computer to be displayed on a television monitor or recorded on a DVD, VCR, video editing bay or other recording device. All of the outputs are NTSC/PAL.

This scan converter accepts one Macintosh or VGA computer input of a resolution up to 1152 x 900 and provides a local monitor loop-out.

The VSC 150 is 1U high and one half rack wide. It is rack mountable, and has an internal, autoswitching power supply. It can be controlled via front panel buttons, RS-232 remote control, and infrared (IR) control.

Features

Picture sizing/zoom controls — Separate digital rotary controls on the VSC 150 allow horizontal and/or vertical picture resizing to fit the display device or zoom in or out. These settings are stored in user- defined memories.

Picture centering and panning — Center the picture horizontally and vertically or pan across the picture with these front panel rotary controls.

Freeze mode — This feature provides a still image of the scan-converted picture.

Filtering controls — Horizontal, vertical and encoder filtering levels are user-selectable from the front panel or remote controls for control of picture detail clarity and flicker reduction.

Memory presets — The VSC 150 offers 30 factory-defined and 30 user-defined presets for size, zoom, panning, centering and filtering settings. These settings can be recalled automatically in association with a particular input signal scan rate. Three additional user-defined presets can be stored and retrieved manually via IR or RS-232 remote control.

Executive mode — To prevent unauthorized or accidental adjustments to the VSC 150’s settings via front panel controls, Executive mode locks all the front panel features except centering controls. Adjustments can still be made via RS-232 control and IR remote control when executive mode is active.

Infrared (IR) remote control — All the functions that can be controlled via front panel controls can be also be controlled via an IR remote control.

RS-232 control — The VSC 150 can also be controlled via computer or another control device through an RS-232 connection and Extron’s Simple Instruction Set™ (SIS™) or the Extron graphical control program for Windows®.

Choice of output formats — NTSC/PAL composite video output is continuously available on a rear panel BNC connector. In addition, one other output can also be active. Choose from the following formats via a rear panel switch and cable connections:

•RGBHV (separate horizontal and vertical sync),

•RGBS (composite sync),

•Y, R-Y, B-Y (component video), or

•S-video output.

Genlock (burst lock) synchronization — The VSC 150 can be connected to a genlock (burst lock/black burst) sync signal generator via rear panel connectors, and the phase differences between the genlock sync and output video sync can be adjusted separately for the
