Primagraphics adds alpha blending and cross mixing to Cobra quad-video windows solution










CHARLOTTESVILLE, VA (PRWEB) May 28, 2004 -

– Primagraphics, the command & control, video and graphics specialist (http://www.primagraphics.com), has launched a new version of its Cobra quad-video windows solution, which supports alpha blending and cross mixing of selected video inputs.

Cobra Ax is a high-performance, multi-input, video windows processor that can accept up to 12 video inputs and then simultaneously display up to four as windows on a digital flat panel or analog display. The key feature of this new card is the ability to alpha blend or cross mix two videos into a single window.

Cobra Ax allows a selected input to be alpha blended with a second input.        

A typical application of this is to combine a scan-converted radar picture with a graphics display. The radar picture may be scaled to fill the graphics window, with the alpha blending providing the mixing of map graphics and radar with the window.

Cross mixing is achieved on the card by using software programmable gains to allow two selected videos to be mixed. For example, using Cobra Ax it is possible to combine video from a thermal and optical camera into a single composite display. The input videos may be unsynchronized and may be scaled and cropped to align them in the output window. Dynamic adjustment of the gain controls allows the display to show optical, infrared or some combination.

Cobra Ax can scale a selected video source to any position on the screen, or can be zoomed to full-screen. Other display configurations include quad-video, picture-in-picture, side-by-side and overlapping windows. Video inputs can be TV, RS170, RS343, STANAG Class A or high-resolution video up to 1280 x 1024.

In addition to video inputs, a high-resolution graphics signal may be input to the card as a separate digital video interface (DVI) or analog RGB video to provide an overlay, or background to the windows.
