1-1. Overview
1-1-1. BKMA-7030
The BKMA-7030 MPEG Decoder 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 and two-channels analog composite video signals (when
the BKMA-7060 is used) are output.
For audio, the audio signals are decoded into four-channels MPEG1 Layer 2 or Linear PCM compressed
audio format, and the SDI embedded audio signal, AES/EBU audio signal, and analog audio signal (when
the BKMA-7060 is used) are output.
The BKMA-7030 consists of the following components.
.DEC-98A board (1)
.Slot label (1)
.Installation guide (1)
.Installation manual (1)
1-1-2. BKMA-7060
The BKMA-7060 D/A Converter Board is mounted on the BKMA-7030 MPEG Decoder Board.
When this board is mounted, the analog composite video signal and two-channels analog audio signals
can be output from the BKMA-7030.
The BKMA-7060 consists of the following components.

General information
.The BKMA-7030 can be inserted into any slot exept slot
No.6 of MAV-70XGI.
.Stick the slot label supplied with the BKMA-7030 onto
the connector panel after the board installation to prevent
the incorrect insertion when the board replacing.
.Do not open the slot to keep the air-cooled effect of
MAV-70XGI. Be sure to attach the blank panel to
vacant slot.
.It is not necessary to adjust after board installation/
replacement.
