A Profile PRO System Overview
The Profile PRO Series are multichannel digital video disk recorders. The
PRO II supports two play/record channels (codecs) of continuously variable
motion JPEG video compression. The PRO III supports MPEG 4:2:0 video
compression, with one record channel (encoder) and two playback channels
(decoders). Each channel can play back one video and up to 4 audio signals,
each capable of using different video formats. In other words, one PRO Series
unit can replace the functionality of up to two VTRs, with the added benefit of
random access to video and audio data stored on disk.
The Profile PRO system has an EISA motherboard with an internal digital
video routing system. There are sixteen EISA slots and one ISA slot used for
interface cards and routing audio data. The PRO III also uses a PCI bus for
routing data between the master enhanced disk recorder (EDR) board and
MPEG board.
A video router chip set is integrated on the mother board. It routes video signals
between the video disk system, video mix effects cards, and video I/O cards.
The video router is a 32 x 32 crosspoint matrix capable of full bandwidth 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 the hardware layout of the PRO Series is shown in
Figure 1 on page 24.
Video Disk Subsystem
In the video disk subsystem, video data is compressed and written to an array
of disks, and then read from these disks and decompressed. This video data is
read from and written to the video router in 8-bit, parallel component digital
video format. The video disk subsystem has enhanced disk recorder boards,
with an Intel i960 real-time processor and a SCSI-2 interface to the disks.
The video disk subsystem uses a master enhanced disk recorder (EDR) board.
The master board has an Intel i960 real-time processor that controls
compression on the two-channel JPEG codec or the MPEG encoder and
decoder board, which is connected to the master via a PCI interconnect board.
The processor also controls the data flows on the master board’s two SCSI-2
channels. The bidirectional JPEG codec channels allow channels to be
configured for recording or playback.
