Functional summary

Video Scaling

The DVICOMP-IS provides automatic vertical and horizontal up-scaling and

down-scaling of the input video, allowing resolutions of up to 1280x1024 to be

displayed on a 625 line (PAL) or 525 line (NTSC) video monitor.

Video Encoder

The video encoder features composite output with sync.

Host interface

The core functionality of the DVICOMP-IS is completely autonomous to the

host PCI bus. The DVICOMP-IS is factory configured for NTSC or PAL output

operation and will auto-detect the input resolution prior to performing the

rescaling.

The PCI host bus is connected directly only to the [optional] mini PCI socket

and enables a range of mini PCI modules to be fitted to the board. The

DVICOMP-IS is specifically designed to accommodate an AMP video codec

module such as the microMPEG4, microMPEG-D4 or microH264-D4. The PCI

connector is also used to provide the power supply to the board. Alternatively,

input power may be connected via the screw terminal block.

Please note: mini PCI is specified for 3.3v operation only and therefore the

DVICOMP-IS is a 3.3v add-in card when used with a mini PCI module.
