Using TimeDelay
NOTE: A time-locked version of this optional software was shipped to
you with version 2.2 system software. Unlocking this software
requires an additional purchase. Click Purchase in the timelock
dialog box for information on how to purchase this software.
TimeDelay enables a Profile disk recorder to record incoming video and delay
the playback a user-specified amount of time. Figure 134 illustrates the
conceptual model for TimeDelay. Video enters the system at timecode
00:00:00:00. Record begins at a given time (according to the clock on the NT
server) or is manually started. Playback is started based on the specified delay
time for the playback channel. When the record channel reaches the specified
delay time, playback begins. You can also start playback manually.
The maximum delay length for the Largest Delay field depends on the current
available disk capacity of the disk recorder. Once the Largest Delay has been
reached, playback occurs in a continuous loop.
If the censor channel is used, it can edit recorded clips that have not yet been
played back. Referring to Figure 134, this means the censor channel would be
positioned within the specified delay time limits.
