Introducing the Profile Family
The Profile PDR100 Video Disk Recorder and the Profile PDR 200 and
PDR300 Video File Servers store broadcast-quality motion JPEG or MPEG
(PDR 200 and PDR300 only) video and CD-quality audio on computer disk
drives rather than on vide o tape, allowing almost insta nt access to any timec ode
location of your video and audio material.
A Profile system is more than just a one-for-one replacement of a VTR: it can
have up to six record and eight playback video channel s. Clips are availa ble on
all channels at once, s o you can play a clip on more than one channel at the same
time, without making a copy of it. Since each channel is independent of the
others, each playback can start at a different time and at a different place in the
clip.
You can even start playing a clip while it’s still be ing recorded. Just start
capturing the clip on one chan nel, wait about five seconds, and then pla y the clip
back on another channel. This kind of control makes the Profile system an ideal
solution if you wa nt to go to air with a clip before you are f inished recording it .
NOTE: Profile Syst em Software version 2. 5 supports the PDR200, the
PDR300, and, when upgraded with a Master and Slave Enhanced
Disk Recorder (EDR) boards, the PDR100. In addition, version 2.5
runs on Microsoft Windows® NT™ 3.51 and 4.0.
This version of system softwar e offers support for the MPEG-2 4:2:2 @ Main
Level encoder/decod er boards, which are standard in the PDR300. Upgrading
your PDR200 with MPEG can approximately double its video/audio storage
capacity and enables much faster data transfers over Fibre Channel. The MPEG
encoder offers both 4:2:2 and 4:2:0 chroma sampling, variabl e bit rates from 4
Mb/s to 50 Mb/s, and group of picture (GOP) structures from I-frame only to
16-frame GOPs.
MPEG u s es mo ti on p r edi ction t o in cr e as e ef f ic ie n cy —essentially , it u ses lower
data rates because it does not duplicate video that does not change from frame
to frame. MPEG accomplishes this through both backward and forward
prediction. To do this, it uses GOPs, consisting of I-frames, P pictures and B
pictures.
Profi le Fami l y21
Chapter 1Introducing the Profile Family
An I-frame (also known a s an I-picture or Intr a-picture) is a nalogous to a single
motion JPEG frame, where all data required to display a frame is stored in one
picture. A P picture (also called a predictive picture) uses a motion vecto r to
predict what will happe n in the next frame and cont ains only the change d data,
rather than passing along an other complex frame of video. In addition, a
B picture (known also as a bidirectional picture) relies on data from both
backward and f orward motion vector s to determine how a future frame will be
composed. In general, the longer the GOP, the more efficient your MPEG video
stream will be.

Chapter 1Introducing the Profile Family
A Profile System Overview
The PDRseries of video servers are multichannel digital disk recorders. Both
the PDR100 and PDR200 are capable of supporting up to four play/record
channels (codecs) of continuously variable motion JPEG video compression.
The PDR200 and PDR300 support Fibre Channel networking and MPEG
4:2:0/4:2:2 video c ompression, with up to two record channels (encoders) and
up to eight playb ack channels (decoders) . Each channel can play ba ck one video
and up to 16 audio signals, each capable of using different video formats. In
other words, one Prof ile unit can rep lace the f unctiona lity of up to eight VTRs,
with the added benefi t of random acc ess to video a nd audio da ta stored on disk.
The Profile system has an EISA motherboard with an internal digital video
routing syste m. There a re sixteen EI SA slots and one ISA slot used for i nterface
cards and routing audio data . The server also uses a PCI bus for routing data
between the master and slave enhanced disk recorder (EDR) boards, Fibre
Channel boards, and MPEG boards.
A video router chip s et is inte grated on the mother board. It rout es video signa ls
between the video disk system, video mix effects cards, and video I/O cards.
The video router is a 32 x 32 cros spoint matr ix capable of full band width 4:2:2
CCIR 601 8-bit digital video. The video router allows real-time transfer of
video throughout the system without impacting overall system performance.
The video router also makes possible simultaneous record and playback on
separate channels .
A block diagram showing t he hardwa re l ayout of a PDR200 or above is shown
in Figure 1 on page 27.
Video Disk Subsystem
In the video disk s ubsystem, vi deo data is compre ssed and writte n to up to eight
4-gigabyte ( PDR100 only) or 9-gigabyte disks, and then read from these disks
and decompressed. This video da ta is rea d from and written to the video router
in 8-bit, paralle l component digita l video format. The vi deo disk subsyste m has
disk recorder boards (PDR100) and enhanced disk recorder boards (PDR200
and above), with an Intel i960 real- time processor and a SCSI-2 inter face to the
disks.
The video disk subsystem us es master and slave disk rec order or enhanced disk
recorder (EDR) boards with two SCSI-2 channels on each board. The master
disk recorder board comes sta ndard with a two-channel JPEG codec.
Bidirectional co dec channe ls allow channels to be configured for recording or
24Profi le Fami l y
playback. By adding a sla ve disk recorder board, a Profile unit becom es a fourchannel JPEG system. The master board has a Intel i960 real-time processor
which controls compression and the data flows on SCSI-2 channels and JPEG
codecs. Master and slave EDR boards also control MPEG encoder and decoder
boards which are connected to the master and slave via a PCI interconnect
board.
Video Compression
The i960 on the master board is used to control dat a flow and compre ssion
coefficient loading of the JPEG codecs and, if present, MPEG encoders and
decoders. The amount of JPEG video compression varies according to the
setting of the compr ession coefficient; the amount of MPEG video compression
varies according to the bit rate. Higher compression ratios or bit rates store
more video, but the result is lower quality video. On the other hand, lower
compression ratios or bit rates result in higher quality video and less storage
capacity. Audio, however , is not c ompressed.
Since the video compression ratio can be varied to change the video quality
given available storage time, the amount of storage depends on your choice of
compression ratio. A quick rule of thumb is that five minutes of JPEG
video—plus four channels of audio and two channels of timecode—is roughly
equal to one gigabyte of disk stora ge at 75,000 bytes per field in the 525
standard video format. For example, a PDX208 Disk Expansion unit expands
storage up to twelve hours and a PRS200 RAID Storage System can bring it up
to approximately 96 hour s. For vide o stored in t he MPEG forma t at an average
24 Mbps, you can just about double these capacit ies.
In addition to video compression, the disk recorder boards also integrate the
digital audio data coming from the EISA bus, with typically four channels of
audio per channe l of video ( up to 32). Th ese recorder boa rds communica te with
the SCSI-2 interface using a Direct Memory Access (DMA) interface. The
PDR200 also supports the a udio signal proc essing board (ASPB). This board is
capable of delivering 16 channels of analog, embedded digital, or AES/EBU
digital audi o. The PDR200 can be equipped with t wo of thes e boards, for a total
of 32 channels of audio.
Video Compression
Video and Audio Interface Boards
Video and audio interface boards receive incoming and send outgoing video
and audio data . These boa rds are r esponsible f or convert ing the video and audio
to internal formats use d by the video serve r.

Chapter 1Introducing the Profile Family
The PDR200 and PDR300 come with the Audio Signal Processing board
(ASPB). This audio architecture accepts and simultaneously pr ocesses sixteen
audio inputs and outputs. Internally, all audio is processed with a selectable
storage resolution of 16 or 20 bits. Inputs may be individually clocked in groups
of four, and any clock g roup may be refer ence d to the system reference (house
black) or any one of four video inputs. Output clocking is synchronous to
system reference. Sample rate conversion is available for all inputs (30 to
50kHz), providing uniform storage at 48kHz.
You can configure the PDR200 or 300 to operate with analog, AES/EBU
digital, or embedded (SMPTE 272M Level A) audio, depending on which
options are install ed in your system. All three audio formats are support ed
without external conversio n equipment. Analog audio is only availabl e with an
optional PAC208 or PAC216 Analog/Digital Interface chassis. You can
expand the number of XLR or BNC connectors for AES/EBU audio with an
optional XLR216 or BNC216 Digital Interface chassis.You can choose an
audio format for each video channe l. F or example , you c ould enable analog
audio on one channel, embedded audio on another, and AES/EBU on the rest.
There are severa l video boards tha t allow a Profi le vide o serve r to be used with
various standard vide o formats: c omposite analog , seri al digita l component , or
component analog vide o are all possible . All boards accept 525 or 625 (NTSC
or PAL) video standards.
The latest a nalog com posit e input and out put b oard offers two input and ou tput
channels per board. The two output channels for this board are similar to the
output channels of the original analog composite board. An analog composite
monitor board allows you to display text and burn-in timecode on an output
monitor.
The component analog input allows dithe ring, auto-timing, and vertical
blanking. As with other inputs, you can automate VITC detection. You can
adjust input gain and also sele ct an input format such as Betacam.
A serial digital component boa rd provides two channels of both input and
output, plus embedded audio when used with an ASPB. You can also enable
dithering, auto-timing, and automate VITC detection. The board a lso has error
detection and handling.
The standard refe rence genl ock board allo ws you to t ime your Prof il e server t o
other devices in a broadcast facility. You can lock a Profile unit to a PAL or
NTSC reference signal (hous e black). The genlock board also lets you have
LTC inputs and outputs, with four inputs and four outputs possible for each
channel.

Profile Software Development
The Profile Software Devel opment Kit (SDK) provides an application
programming inte rface (API) for libr arie s of P rofile func tions. We rec ommend
that you call these functions via Microsoft Visual C++ 5.0; however, it is
possible to use other langua ges that permit calls to C declared functions
(contact your Grass Valley Group representative for more information).
Software developers can use the API to control the Profile from third-party
hardware devices, for example. The API consists of seven libraries:
• The TekCfg library provides an interf ace to the Profile configuration.
• The TekPdr library furnishes calls that inventory and manage movies in
Common Movie Format (CMF), an internal file format standard for video,
audio, and timecode.
• The TekRem library makes it possible for a remote Windows NT syste m to
control a Profile disk recorder over an Ethernet LAN.
• The TekVdr library provides an inter fac e for playing and recording video
and audio clips.
• The TekVfs library suppor ts low-level ac cess to individua l media files i n the
media file system.
• The TekVme library controls the optiona l video mix effects board.
• The TekXfr library supports media stre aming of Fibre Channel connecti ons.
Eight RS-422 se rial ports come standar d on a disk re corder. A dis k recorder can
issue serial commands or receive them from an external device via RS-422
communication lines. The Profile Protocol associates each API call with a
specific number that can be sent over an RS-422 line. The ProLink app lication
monitors Profile Protocol calls over an RS-422 link, allowing you to use
compatible hardware devices, such as the PRC100 Control Panel, to issue
commands to a Profile unit.
Windows applications are also available to control the Profile system. Your
disk recorder comes with several standard and optional applications. See
“Starting and Closing Profil e Applications” on page 31 for more information.
NOTE: Louth and Odetics RS-422 protocols are also supported,
although th ere i s not a one-to-one co rre spondence be tween these
protocols and the Profile API. Louth and Odetics protocols do not
allow you full access to the functionality of the Profile system.
