Having been initially designed for a specific survey contractor equipment tender in mid 2008, we are pleased to offer IVM for general release from Q4 2008.

A software application for the automated control of up to 4 primary DVRs and up to 4 additional Black Box recorders. This Integrated Video Management (IVM) software is installed on a 2U high rack mounted PC which has a built-in RAID 5 storage array. Additional hardware includes multiple USB and network connections, DVD burner and various Flash Memory Cards.

The IVM GUI, seen opposite is a single page user screen split into two sections. The top section is the interface to the Dive Log with the bottom section being reserved for the display of the setup page, status page and video overlay page. These pages are accessed by clicking on a Tab or using the “F” keys on the keyboard.

The example screen demonstrates the master slave set-up with Channel 1 and 1 as Masters and channel 3 and 4 as slaves. Also seen is the drop down events menu video channel naming capability.

"F" keys also used to access hideable quick select event keys.

The set-up screen enables the operator to configure the video suite for operation by setting a number of parameters and choosing a number of options including:

• select multiple DVR operation
• set up the Master Slave matrix
• allocate names to video channels
• configure auto video overlay options
• select format and bit rate
• select location to store video files
• configure file naming nomenclature
• set up back up regime

Video Overlay Screen
The video overlay screen enables the operator to configure the video overlay and check the data is in the correct place. It allows the operator to:

• select the channel on which to display the overlay
• set display names for the channel, if different from the set-up page
• create saved pages for quick call up, e.g. header pages
• parse data strings e.g. GPS
• enter free text on the screen
• preview all serial data positions

Status Screen
The status screen gives the operator an overview of how the system is operating, checking the DVRs are all functioning and displaying the status of each DVR e.g. recording or stopped. This screen will also display all video images that are being encoded, whether it is a single channel or 3 channels of video from a pipeline survey and pipetracker data.

It is envisaged that this would be the screen that the operator would view in normal operation.
