4-2. BKDE-550/560 Overview of
Operation
The BKDE-550 RAE (Random Access Electronics) con-
tains audio and video processing circuitry, a sync generator,
a system processor, a motherboard, system interface panels
and a power supply.
BKDE-550 RAE processes include;
Y Compression and decompression of video signals
transferred to and from storage
Y Digital to analog and analog to digital conversions for
video and audio
Y Communication with external SCSI and serial
communication devices
Y Sync generation and system timing management
Y Transfer of digital audio to and from the Disk storage
electronics
Y VTR and external signal interfaces
Y Host PC and editing control unit interfaces
An internal VME bus is employed to direct the operations of
each of the boards within the chassis. Three SCSI ports, 4
serial ports, two high speed DMA busses and 2 channels of
video and audio interfaces are utilized to control, store and
playback the audio and video material directly from hard
disk.
The BKDE-560 Disk chassis contains the desk storage sys-
tem which is comprised of user option selected BKDE-561
video disk drive sets and BKDE-562 Audio disk drives. It
communicates and transfers information with the BKDE-
550 via SCSI 2 interfaces.
