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.
To operate, either of the two main Audio Decoders (ports) on the i6420, #1 or #2, needs to
have a permanent assignment to a valid audio stream in the currently-received Transport. 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
