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.
