Glossary
128 Profile Family
Keyboard
An alphanumeric input device that allows communication with software
applications.
Library system
The Profile Library System (PLS200) is a robotic tape library that provides
affordable mass storage for the Profile video disk recorder.
LTC
Longitudinal Time Code is typically an analog audio track or a dedicated
address channel on a tape. LTC can't be read in still mode, and may not be
reliable during low-speed shuttle operations.
Media files
Audio, video, and timecode sources that have been captured by the Profile
disk recorder are considered media. Media is stored on disk as media files.
Audio and video clips do not contain media, but instead reference positions
in a media file.
Memory
A component of a computer system used for virtually instantaneous
temporary storage and retrieval of information (data) or instructions
(programs). Information in memory is volatile, and is lost when the
computer is shut down. Storing information on a permanent storage device
such as a hard disk or a tape allows for retrieval during another work session.
Menu
A list of commands or functions that you select with a pointer. A menu is
normally displayed in a small window.
Monitor
Two-channel audio output of selected machine tracks. Generally, audio
systems or video displays used in a studio environment to control quality.
Also, a video display device, without audio capabilities.
