1-1. Overview
1-1-1. BKMA-7031
The BKMA-7031 MPEG Decoder with 8CH Audio Board inputs the playback data from the hard disk of
MAV-70XGI and decodes its data to the video/audio signals.
For video, the video signals are decoded with MPEG2 MP@ML or 4:2:2P@ML compressed video
format, and the two-channels SDI video signals output.
For audio, the audio signals are decoded into four-channels MPEG1 Layer 2 or four/eight channels Linear
PCM compressed audio format, and the SDI embedded audio signal, AES/EBU audio signal are output.
n
The software version V2.50 or higher of the MAV-70XGI should be installed before using the BKMA-
7031. If is not installed, upgrade the software version to version V2.50. For the procedure of upgrading,
contact your local Sony Sales Office/Service Center.
The BKMA-7031 consists of the following components.

General information
.The BKMA-7031 can be inserted into any slot exept slot
No.6 of MAV-70XGI.
.Stick the slot label supplied with the BKMA-7031 onto
the connector panel after the board installation to prevent
the incorrect insertion when the board replacing.

MAV-70XGI. Be sure to attach the blank panel to
vacant slot.
.It is not necessary to adjust after board installation/
replacement.
Procedures
1. Turn off the power switches A and B of the MAV-
70XGI.
2. Remove the two screws, and remove the blank panel
of any slot.
n
Keep the removed blank panel.
3. Insert the BKMA-7031 into the slot, and turn the board
levers in the direction of the arrow 1to connect the
