Fixed recording medium
Part of the Final Recording Medium which is protected against fire, shock, penetration and a
prolonged period on the ocean floor. It is expected to be recovered from the deck of the vessel
that has sunk. It has a means of indicating location.
Float-free recording medium
Part of the Final Recording Medium which should float-free after a sinking. It has a means of
indicating location.
Long-term recording medium
Permanently installed part of the Final Recording Medium. It provides the longest record duration
and a readily accessible interface for downloading the stored data.
Module
A physically separated part within a Unit, i.e. signal adaptor or other (part of) assembly.
Playback equipment
Any data medium with the playback software, the operational instructions and any special parts
required for connecting a commercial-off-the-shelf laptop computer to the VDR.
Playback software
Copy of the software program to provide the capability to download the stored data and play back
the information. The software should be compatible with an operating system available with
commercial-off-the-shelf laptop computers and where non-standard or proprietary formats are
used for storing the data in the VDR, the software should convert the stored data into open industry
standard formats.
Playback system
System including the playback equipment that is capable of downloading and playing back the
recorded data.
Recorder, Voyage Data Recorder, VDR
Complete system, including any items required to interface with the sources of input signals, their
processing and encoding, the final recording medium, the playback equipment, the power supply
and dedicated reserve power source.
Resolution
Smallest detectable increment between two values.
Signal source, sensor
Any sensor or device external to the VDR, to which the VDR is connected and from which it obtains
signals and data to be recorded.
Unit
A physical part of the VDR contained in a separate housing, i.e. CM (Core Module) or BCU (Bridge
Control Unit).
