General

The Angelo RTV-24 acquisition board is designed without compromise

for security and video surveillance applications. It's the ideal device

for PC based multiple-channel digital video recording.

This 32-bit, 33MHz/66MHz PCI bus frame grabber can capture

simultaneously four analog video streams in real time. It accepts

standard composite colors (PAL, NTSC) or monochrome video formats

(CCIR, EIA).

The resolution is programmable including square-pixel (640 x 480 or

768 x 576) and broadcast resolution. Before captured images are

transferred to the PC's memory, images can be scaled down using

available selectable ratios.

Arbitrary cropping to regions of interest is possible. The RTV-24

generates bitmaps in all popular color formats such as RGB, YUV,

planar or packed.

System integrators also benefit from a watchdog for fault-tolerant

applications and easy-to-use standard connectors.

Image Acquisition

Frame Rate: 30 full-frame images acquired per second for each

channel.

Color Image: Color video format is compatible with the following

composite video input formats: NTSC-M, NTSC-Japan, PCL-B, PAL-

D, PAL-G, PAL-H, PAL-I, PAM-M, PAL-N and SECAM

Monochrome Image: The monochrome video acquisition is compatible

with CCIR and EIA (RS-170).

Optional Scaling: The acquire images or portions of images can be

optionally scaled:

Acquisition of a programmable area of interest.

Scaling of the image. (down to 1:16)

Adjustment of hue (for NTSC signals), contrast (0 to 200%), brightness

and saturation. (0 to 200% for U and V signals)

Automatic chrominance gain control.

RTV-E4 Extension Board (Optional)

• Channel Extension

Expandable up to 16 channels.

Channel extension interface.

10-pin ribbon cable to onboard 10-pin header

connector for channel extension. Each header

adds 4 video input channels.

Three 10-pin header connectors onboard.

I/O Lines

The Angelo RTV-24 is fitted with TTL compatible I/O lines, supporting

4 inputs, 4 outputs and 4 soft trigger lines with protection against

overloads and electrostatic discharges.

Every line maybe configured as an input or output or can be used to

trigger an acquisition or report an alarm condition.

Watchdog

A hardware watchdog is available on the Angelo RTV-24. The watchdog

is able to monitor the PC's application operation and will automatically

reset the PC after a programmable inactivity time-out. This ensures a

reliable operation of remote systems.

RTV-I4 Isolated GPIO Board (Optional)

• General Purpose I/O Lines.

All I/Os are TTL compatible and support 4 inputs,

4 outputs, and 4 soft trigger lines.

I/O interface.

Two onboard 10-pin header connectors.

The I/O lines are pulled high internally and

have the following characteristics:
