Controller board relieves host processor loading

VAC2000 offers flexibility in mixing these with one another or with computer-generated graphics and text for TV and VGA output.

The VAC2000 hardware relieves host processor loading and enables video systems to be created with low-power, fanless processor boards.

The VAC2000 accepts either two S-Video inputs, or, up to four composite video inputs from video cameras, DVRs, television broadcasts or other NTSC/PAL sources.

Each video input can be alpha blended with another video channel or with graphics using one of 256 translucency levels from opaque to transparent.

The VAC2000's output can simultaneously drive a composite or S-Video TV video monitor (RS170), analogue VGA screen and a DVI (Panellink) flat-panel display.

A preview output can also monitor the input video channels.

The VAC2000 can set alpha blending for a rectangular area or per pixel.

A high-performance 64-bit 2D graphics accelerator and 8Mb frame buffer provide fast video graphics processing, enabling high-speed resizing of alpha-blended images; the live video window can be resized almost instantly from full screen to an icon.

The hardware alpha-blending function can also be used for fast conceal/reveal of the video, text or graphics information.

The hardware also enables multiple video windows to be scaled and displayed on a single screen for picture-in-picture systems.

The VAC2000's SDK reduces development time in Microsoft Windows, Linux and QNX environments.

It includes support libraries, drivers and a range of example applications complete with source code.

These show how to fully utilise the VAC2000's features in complex video/graphic applications.

Applications include merging of daylight and infrared video images for military environments, text annotation of video for traffic monitoring, superimposition of crosshair graphics onto battle-zone target area video, visible watermarking, command and control consoles, vehicle telematics, medical instrumentation, and security installations.

The VAC2000 operates from a single +5V power supply and is available in commercial and extended temperature (-40C to +85C) options.

The PC/104-Plus board uses standard MMCX connectors for the video input and output signals.

AMP can also supply a small panel-mount adapter module, which provides a standard single-link DVI-D socket.
