VAC2000 - Multi channel video annotation / overlay controller
The VAC2000 is a real time NTSC/PAL video overlay and video annotation
controller for the PC/104-Plus (pc104+) bus.
The VAC2000 integrates on a single PC/104-Plus card, a high-resolution
graphics accelerator, digital NTSC/PAL TV decoder, digital NTSC/PAL TV
encoder and video overlay controller. The VAC2000 accepts up to four
composite (or two s-video) NTSC or PAL analog video inputs from a variety
of sources including video cameras, digital video recording equipment or
regular TV broadcasts. It can mix either video and graphics data or, mix
two separate video channels, and provide output to drive a VGA monitor, TV
monitor (as composite video or S-Video) or TMDS flat panel display. The
VAC2000 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 VAC2000 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. The combined annotated information may then be displayed
and/or fed into an MPEG-4 encoder for compression and recording
applications.
The VAC2000 board uses a high performance 64 bit 2D graphics accelerator
and 8Mbytes frame buffer to provide fast video graphics processing to
enable high speed re-sizing of alpha blended images.

Software Development Kit (SDK)
The VAC2000 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 VAC2000 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 VAC2000 in complex video/graphic applications.
