■Common to SS and SD modes

Compliance with MPEG-2 4:2:2 Profile @ Main Level

This unit records video with intraframe compression conforming to the MPEG-2 4:2:2 Profile @ Main Level standard. The recording bit rate can be set to 50, 40 or 30 Mbps to suit the intended video application. Maximum recording time depends on bit rate setting and selected Motion mode, as shown in the following table.

Input/output	30 Mbps		40 Mbps	50 Mbps
signal
Audio	16-bit	20-bit	20-bit	20-bit
SS mode	6 h 20 min	5 h 20 min	4 h 50 min	3 h 40 min
SD mode	19 h 20 min	16 h	14 h 40 min	11 h 20 min

For details about the SD and SS modes, see Section 3-1, “MAV- 555SS Modes” (page 3-1).

High grade AES/EBU digital audio as standard equipment

This unit provides four independent 20-bit/16-bit AES/ EBU digital audio signals on each DSI input/output port. Further, you can record video signals and asynchronous AES/EBU digital audio signals.

Rapid response to scene searches

The design of this unit puts the emphasis on operability as a disk recorder. In particular, the unit provides VTR-like

operability and response for scene searches, while a unique shuttle system reduces frame drop-out. Variable speed playback is supported by the dedicated control panel (using the optional BKMA-505 control panel) and existing external controllers provide jog, variable, and shuttle control with operability and response comparable to that of a VTR. Digital jog sound is supported, allowing audio segments to be found quickly and easily.

Scene searches and other editing operations on frame- based material files can be carried out rapidly and accurately.

To enhance its function as a disk recorder, high speed cue- up for editing points is also possible.

Real-time playback process control

Process control of audio and video inputs and outputs can be carried out in real time, using the level adjustment knob on the front panel of the unit.

Menu-driven setup

The operating conditions, initial settings for interfaces to other devices, and other settings can be controlled by menu operations on the front panel of the unit.

Nonlinear editing functions through the control panel

The optional control panel (BKMA-505) can be used to perform nonlinear editing through a user interface similar to that used for conventional VTR editing. Furthermore, independent audio channel editing is possible for up to 4 channels.

Note

Version 2.30 or later is required for the control panel (BKMA-505).

Broad range of information displays

The large display panel displays information on the operation of each of the ports (maximum four) in this unit. The displays include timecode values, error messages, setup menu information, HDDs space used and remaining capacity, and audio levels for each port.

Plug-in printed circuit boards/HDDs

Plug-in components allow easy replacement of printed boards and HDDs, keeping maintenance simple.

Self-diagnosis functions

If a fault occurs in the system or in a HDD, the cause is diagnosed, and an error code appears on the display panel.
