Introducing the Profile Family
The PDR100 Profile Video Disk Recorder and the PDR200 Profile Video File
Server store broadcast-quality video and CD-quality audio on computer disk
drives rather than on tape, allowing almost instant access to any location in 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 four video channels which is like having four independent VTRs in
one unit. Clips are available to all channels at once, so 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 being recorded. Just start
capturing the clip on one channel, wait about five seconds, and then play the clip
back on another channel. This kind of control makes the Profile system an ideal
solution if you want to go to air with a clip before you are finished recording it.
Table 1 on page 2 lists and compares other features of the PDR100 and PDR200
in detail.
