3.7.3.Time Zone Delay

The new premium Time Zone Delay (TZD) feature allows network operators to save satellite bandwidth by only having to transmit the feed for the easternmost time zone in his coverage area. With Time Zone Delay, iPump6420s in the time zones further west can store and replay the same audio track, with associated Compel commands, at the same local time everywhere. In operation, this feature operates as a large rolling time-delay buffer, which can be set to delay and play on any delay up to 4 hours.*

* Contact WEGENER Sales Dept about the option for larger time delay settings.

Then Time Zone Delay acts like a permanent “add-on” setting. When first activated, the normal live audio track will continue to play and the associated Compel commands for inserts and relay closures will continue to execute. However, the unit will also begin recording that audio and the associated Compel commands, in a manner similar to that done with ShowShifting (see Section 3.7.2). When the total content recorded reaches the value of the TZ delay time, then the i6420
