VAC4000 - Multi channel VGA controller with video annotation / overlay
The VAC4000 is a dual output VGA graphics controller with real time
multi-channel NTSC/PAL video overlay /annotation functions for the
PC/104-Plus (pc104+) bus.
The VAC4000 includes a dual output, high-resolution 2D/3D graphics
controller, 4 channel NTSC/PAL TV decoder, digital NTSC/PAL TV encoder
as well as optional TMDS / LVDS flat panel outputs. The VAC4000 accepts
up to four composite NTSC or PAL analog video inputs from a variety of
sources and enables these to be combined with the graphics display
outputs. The dual, independent outputs can drive a combination of
analog (RGB) VGA, digital flat panels or an analog TV output.
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 VAC4000 board uses a high performance 2D/3D graphics accelerator
with an 8Mbyte integrated frame buffer to provide fast video graphics
processing and enable high speed image re-sizing.

Software Development Kit (SDK)
The VAC4000 is supported by a comprehensive SDK which provides a high level API to configure and control the embedded video hardware. The VAC4000 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 VAC4000 in complex video/graphic applications.
