Pre-Read
Also known as "read before write." The ability for a digital VTR to read digital
information (audio and video) off tape - prior to writing the data back on tape.
Preset Bus
The switcher bus that selects the video that will appear next on-line or on-air.
Program Bus
The switcher bus that selects the on-line or on-air output signal.
Serial Digital Video
Also called SDI, a digital representation of the video signal that is distributed via a
single coaxial cable with BNC connectors. This format is more desirable and cost-
effective than a parallel interface which requires multi-conductor cable.
Setup Menu
A secondary BVE-9100 menu used to set up devices, crosspoint assignments and
I/O (input/output) communications.
Status reporting
A system of bi-directional communications that allows the panel status of peripheral
devices to be reported to (and stored in) the BVE-9100's EDL in real-time.
TBC
Time Base Corrector. A device used to stabilize a VTR's unstable image. Includes
controls for adjusting the brightness, black level, color hue, and color saturation of
the video playback.
Time Track
A powerful, software-based feature for finding matching video frames in the EDL.
Match frames enable you to synchronize machines and perform clean, seamless
transitions in a program. The BVE-9100 has a variety of Time Track modes.
Timecode
A numeric method for identifying video frames with precision. Each frame of video
is assigned an unique 8-digit number (hours, seconds, minutes, frames). Enables
precise match-frame editing transitions.
Trace
A list management tool that traces back to "original" source reel timecode numbers
across multiple EDLs. Let's say that master tape #1 is a rough cut. If master tape
#1 is next used as a source in the second cut (producing master tape #2), the
original source reel timecodes are one EDL generation back. If the process is
repeated again, the original numbers get farther away, but they're not lost. If you
