3-12 Video Disk Configuration
If you never use more than 9 segments in any ID, select 1 character (which allows up to 9
segments). If you select 2 characters here, a maximum of 99 segments is allowed. Valid
numbers are 0, 1, and 2. Default is 0.
Archive Tab
Archive Configuration
Disk Has Archive . Default is enabled. It is recommended to keep this parameter enabled
even if a disk does not have an archive. Archives require ADC-100 to check if a disk can
get an ID from an archive. If a communication error has occurred such that an ID in the
disk is not known by the ADC-100, it checks with the disk if needed (if disabled, it
depends on the disk keeping the Device Storage Window to be up-to-date at all times).
When enabled, there can be a much larger communication load between ADC-100 and the
disk if many red events are in the play list, but the ADC-100 can handle virtually any load.
This feature is normally only disabled for testing and troubleshooting to reduce
communications, as the system can generally handle the load and automatically detects if
an archive is present.
Backup Play From Archive . Enable this parameter if the disk port supports this function
(most video disks do not support this function). When the parameter is enabled, and if the
disk uses an archive system as the source for spots, the disk plays a spot directly from the
archive if it is cued for playout before the spot is transferred from archive to the playout
disk. This occurs only if an event is placed on the playlist seconds before it is to go on air.
Normally, every spot is transferred from archive to the playout disk when the spot reaches
the lookahead area of the list (which usually happens hours before playout). Default is
disabled (unchecked).
