84 File Names
To avoid confusion,
don’t duplicate file
numbers.
File numbers are used to identify which file is to be played in
response to Select File serial commands or rear panel file selection
parallel inputs. File numbers contained on a drive should be unique,
regardless of the file type. In other words, you shouldn’t have
PLY00002.LST and VID000
02.MPG on the same drive. The two files
should have different numbers. If more than one file has the same
number, the first file found in the directory will be used.
Autoexec files are
invaluable in stand-
alone applications.
File 00000 is
an autoexec file. A file numbered 00000 is automatically
executed on power up. For example, Playlist PLY00000.LST will start
as soon as the Digital Video Machine 2 is turned on. If the loop input
is strapped on, or if the Playlist is designed to repeat, playback will
continue indefinitely.
The order of precedence for file execution is:
1. Command File
2. Schedule
3. Random Playlist
4. Playlist
5. Video
Long file names and file names not containing numbers are not currently
supported.
