Product Description
Profile Video File Server Installation 1-3
Product Description
The Profile Video File Server is a disk-based video file server with enhanced record
and playback quality, and rapid storage/retrieval capabilities. In addition to the
advantage of not having to load tape as with VTRs, the Profile Video File Server
occupies less rack space and is fully computer controlled.
The PDR200 provides up to four Motion-JPEG encoders/decoders (CODECs) in a
flexible system which starts with four base configurations: two are for 2-channel
Profile systems and two are for 4-channel Profile systems. These base configurations
can be ordered with analog or digital inputs and outputs. Each configuration is then
tailored, through factory installed options, to meet your site-specific needs. Many
options may be easily added to your PDR 200 as your needs change and expand. For
information on adding options, contact your Grass Valley Group representative.
A two-channel system (PDR 202) is equipped with a single Master Enhanced Disk
Recorder board, which provides two JPEG codecs, and two SCSI busses, SCSI A and
SCSI B, although SCSI B may not be available on all models. A four-channel system
(PDR204) adds a Slave Enhanced Disk Recorder, which provides two additional
JPEG codecs and two more SCSI busses (SCSI C and SCSI D).
The PDR300 adds factory-installed MPEG encoders and decoders to the Profile
Video File Server, while retaining all the capabilities and optional configurations of
the PDR200. Two MPEG boards, one with one encoder and two decoders, the other
with four decoders, provide many combinations of capabilities to meet your needs.
The JPEG codecs on the Master and Slave Enhanced Disk Recorder boards remain
available as resources for record/play channels or for transcoding clips between JPEG
and MPEG.
The PDR 400 adds factory-installed DVCPRO boards to the Profile Video File Server,
while retaining the same capabilities and optional configurations of the PDR 200. The
DVCPRO boards includes up to six DVCPRO 25 codecs arranged in pairs. Each pair
of DVCPRO 25 codecs may be used as a single DVCPRO 50 codec. Because of this
paired codec architecture, some system timing restrictions apply. These restrictions
are discussed in “DVCPRO System Timing Considerations” on page 1-17. The JPEG
codecs on the Master and Slave Enhanced Disk Recorder boards remain available as
resources for record/play channels or for transcoding clips between JPEG and
DVCPRO. In some configurations, the operation of one of the JPEG codecs may be
restricted as described in “Configurations” on page 1-8.
The Profile Video File Server is mounted on rack slides for installation in a standard
electronic equipment rack. All connections to the Profile Video File Server are on the
rear panel (see Chapter 2, “Mechanical Installation”). Also see Appendix A,
“Specifications”, for physical and electrical specifications and environmental criteria.
