Chapter 1 Overview
1-2 Features 1-3 (E)
Security
This unit provides the following functions expected of
equipment in broadcasting stations.
Data protection
In case of HDD failure, RAID technology is used to ensure
that data recovery is possible. For example, even if a drive
fails during recording, an equivalent drive interpolates the
data, allowing operation to continue.
Help function and information displays
If there are any problems in system operation, error
messages appear on the front panel.
Vibration resistance
The robust construction is resistant against vibration and
dust, allowing the unit to be used in vehicle-borne
situations. In particular, to protect the HDDs, they are
mounted in special caddies independent of the main
chassis of the unit.
Rack mounting
The unit can be mounted in an EIA standard 19-inch rack
(optional rack mount kit RMM-555 required).
For details of rack mounting, refer to the Installation Manual.
■ SD mode only
Multi-access, Multi-operation
(Simultaneous recording/playback
operations possible while recording)
One of the advantages of a hard disk recorder (such as the
MAV-555SS) over a conventional VTR is the ability to
simultaneously access, edit, and output material (stored as
files) that is being recorded. The MAV-555SS has four
input and output ports standard. Each port can record or
playback one video channel and four audio channels. 2
input/2 output, 3 input/1 output, and 1 input/3 output
input/output port configurations can be selected on the
Setup menu. An external editor or control panel can be
used to perform multiple editing/output operations
simultaneously.
Flexible I/O Configuration Possible
Various I/O and control panel options are set according to
the external equipment that is connected and the operating
environment. The standard input and output
configurations of the unit and when various optional
boards are installed are shown below.
For details on the basic options, refer to Section 1-4, “Optional
Accessories” (page 1-4).
Linear editing functions
The MAV-555SS is equipped with the “BVE mode”, an
operation mode that provides the unit with linear editing
capabilities. If the operation mode is switched to BVE
mode, the MAV-555SS recording and playback ports are
integrated, and the recorder can then be used as a
recording/playback VTR. This mode allows the MAV-
555SS to be connected to editing machines such as the
BVE-600 or the BVE-2000 as a “recorder/player”. Note
that in other modes the MAV-555SS playback port can still
be connected to editing machines such as the BVE-600 or
the BVE-2000 as a “player”.
The following functions are supported when using the
BVE mode.
• Independent audio channel editing of up to 4 channels.
• Operation of the optional MAVE-F555 editing panel and
the MAVE-D555 dial panel.
• Control by LTC from a BVE editor.
• Auto Assembly editing from a BVE editor.
Ability to record asynchronous signals
By setting the standard signals of each recording port as
input signals, input signals that are asynchronous with the
reference signals can be recorded.
