The Orion 20", 21" and 23" UDP with its video processor provides multiple graphics, text, and live video all within the display eliminating the need for additional hardware. The Orion UDP is capable of two main computer inputs and viewing up to four live sources simultaneously in its standard package. The live sources can be analog, RGB or NTSC and each windowing system can be enabled or disabled as needed. The windowing systems support chroma-keying and magnification. While keeping the aspect ratio, the window may have any rectangular shape and size required by the operator. User profiles can be saved. All these features are controlled through SoftMenus which uses an RS232 serial interface from the computer to the display.
