Optimizing the Image

After you have installed the scan converter, follow the procedures in this section in sequence. This will help you configure the scan converter for the best settings for your display environment.

Select the output standard

1. Select the output standard with the PAL Out DIP switch. This switch affects both display outputs (com-

posite video and one other), but not the local monitor.

ON — The output is in PAL format.

OFF — The output is in NTSC format.

Size the image to fill the screen

1.

Press the Size button on the front panel.

2.

Rotate the vertical and horizontal Centering/Pan/Size

 

rotary controls to adjust the vertical and horizontal

 

size. Observe the picture on screen as you adjust the

 

controls. The Min/Max LED will light red when the

 

minimum or maximum limit of a control is reached.

 

The size feature affects both display outputs, but local

 

monitor loop-out is not affected. The size function

 

remains active for 8 seconds after the rotary controls

 

become inactive. The rotary controls then default to

 

the standard centering and pan functions.

3.

Press the Size button again to turn the size feature off.

4.

Center the picture by rotating the vertical and

 

horizontal Centering/Pan/Size rotary controls.

5.

Repeat steps 1 through 4 as needed.

Select the filtering levels

1.

Press the horizontal, vertical and encoder filtering

 

controls to select the filtering levels that give the best

picture sharpness and the least amount of flickering. The LEDs next to each control will light to indicate the selected level of filtering.

If the filters are set before the image size is adjusted, you must set the filters again after adjusting the image size.

Setting Up Genlock and

Vertical Interval Switching

A genlock (black burst generator) device can be connected to the VSC 150 to synchronize it with other system compon- ents for seamless vertical interval switching between sources.

Vertical interval switching setup

For vertical interval switching (to allow clean switching between signals from several devices during the vertical blanking period of each signal), a composite sync signal can be applied at the Genlock In connector, and also passed to another device via the Genlock Out connector.
