The eVAC4000 is a real time NTSC/PAL video overlay and video annotation controller for PCI-104 systems. The eVAC4000 integrates on a single PCI-104 card, a high- resolution graphics accelerator, digital NTSC/PAL TV decoder, digital NTSC/PAL TV encoder and video overlay controller.

The eVAC4000 accepts up to four composite NTSC or PAL analog video inputs that feed two video paths. Each video path can display any combination of the 4 video inputs, with flexible sizing and positioning under software control.

The eVAC4000 drives VGA and HDMI displays and provides composite and S-video NTSC/PAL video output for display on a TV monitor.

The eVAC4000 features multi-format alpha blending hardware allowing graphics/video and video/video to be alpha-blended over a number of gradations from transparent to fully opaque.
