Live PAL/NTSC Video Annotation Controller for PCI-104

The eVAC2000 is a real time PAL/NTSC/RS-170 video overlay and video annotation controller for the PCI-104 bus.

The eVAC2000 integrates on a single PCI-104 card, a high-resolution graphics accelerator, digital PAL/ NTSC/RS-170 TV decoder, digital NTSC/PAL TV encoder and video overlay controller. The high performance eVAC2000 accepts up to four composite PAL/NTSC/RS-170 analog video inputs from numerous sources including video cameras, digital video recording equipment, and video instrumentation. It can mix either video and graphics data or, mix two separate video channels, and provide output to drive a VGA monitor, TV monitor or TMDS/LVDS flat panel display. The eVAC2000 video annotation controller 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. The eVAC2000 is suited to a wide range of applications which require annotation of live video streams with information such as titles, dynamic grids or visible watermarking.


  • Multi-channel video annotation controller
  • Four PAL/NTSC/RS-170 inputs per board
  • Analog Outputs to PAL/NTSC/RS-170, VGA
  • Digital Outputs to DVI and LVDS for flat panels
  • Alpha blending – 256 levels of per pixel blending or, by defined rectangular region
  • Single +5V power requirement
  • Comprehensive SDK for Windows, Linux and QNX
  • Low power rugged PCI/104 form factor
  • Operating temperature: -40°C to +85°C


The eVAC2000 is supported by a comprehensive SDK which provides a high level API to configure and control the embedded video hardware (via more than 500 internal registers). The eVAC2000 SDK is available for a one- time fee and helps bridge the gap between the TV and computer display technologies and saves a significant amount of development time.

The SDK consists of support libraries and drivers as well as an extensive range of example applications (including source code). These examples show how the SDK can be utilized to harness the power of the eVAC2000 in complex video/graphic applications.
