VIDEO MODULE

Introduction

The Video Module captures RGB, RGBHV, Monochrome, and composite video information from
radars, video cameras, ECDIS, and other video sources.
The Video Module has 4 input ports for capturing images from a dedicated buffered output port of
the video source. Normally only the primary radar is recorded. The module digitizes the video
signal and then outputs the video data through an Ethernet port. . Video modules can be
configured for 4 inputs, enabling the VDR-100G3 to capture and record images from the primary
radar plus up to 3 additional video sources. During installation, the video system must be
configured to accept each source's video resolution, interlacing, refresh rate, etc.
Refer to Chapter 2: Specifications for Video Module capture specifications.
Information is gathered from the <VidChanX.ini> file (based on its VIDEOFORMAT entry
information.) If more than 1 source is specified by the MAXSOURCES entry, then Control
Input/Output connector signals are used to indicate the currently active source. The video signal
configuration is read and a new image is captured. If the system is configured for 2 or more video
channels, then the next channel in the sequence is selected.
NOTE: If the video module fails to capture an image because there is no video
signal (i.e., radar is OFF), an entry is made in the error log. However, this failure
will not generate a video error alarm on the OAU. A video error alarm is only
triggered when a failure is detected in the video capture hardware (i.e. bad or
unpowered video module or Ethernet cable path failure.
