You can delay the broadcasting of an input stream by selecting Enable time shift and then creating a Delayed input stream that uses the Input with the time shift as a source. In this case the input stream will be stored on the local disk, while a variant of the input is created and delayed according to the specified duration. The input stream of the time-shifted stream will be stored on the local disk. In parallel, you can create a "Delayed" stream that will stream the "time-shifted" input stream according to the specified delay. For example, you can specify a 6-hour time-shift to "stream_A". This means that 6 hours of streaming are stored. You can then create a delayed stream that will stream "Stream_A" with a two-hour delay. This means that the delayed stream will always stream with a two-hour delay.

The duration of the delayed stream should be less or equal to the time-shifted stream.

To Add a Delayed Stream:

Make sure at least one of the existing inputs has the Enable time shift setting selected.
In the Zixi Broadcaster Navigation menu, click the Inputs tab.
In the Menu bar, click New Input. The Add a new input stream window is displayed.
Enter the unique Stream I.D.
Select the maximum concurrent connections to this stream from the Max. Outputs drop-down list. Default: Unlimited.
Select the Show in Matrix checkbox to display this stream in the Matrix (see Using the Matrix). Default: Selected.
Select Delayed for the input stream.
Specify the Stream Parameters (see Input Stream Parameters Table).
If you want to Enable time shift, select this checkbox (see Input Stream Parameters Table). For more information, see Encrypting an Input Stream in Zixi Broadcaster.
If you want to Enable multicast on pull outputs, select this checkbox (see Input Stream Parameters Table).

Click OK.

The “Input added” message appears on the top of the screen. The Delayed Stream is added to the Zixi Broadcaster and now appears in the list of streams available in the Zixi Broadcaster inputs UI.

Input Stream Parameters Table

Parameter	Description
Stream parameters
Source	Select one of the input streams that were configured to enable "time shift".
Delay	Specify the delay period relative to the original stream in the following format: hh:mm:ss
*Enable Time Shift*	Select this checkbox to record the stream content and broadcast it after a specified delay. To deploy an input stream that uses the current stream's time shift, you need to configure a "Delayed" input stream. (See Adding Delayed Streams).
Maximum delay [hh:mm:ss] (for Time Shift enabled)	Specify the maximum time delay of this input.
*Enable multicast on pull outputs*	Select this checkbox to enable the transmission of this stream’s outputs as multicast. A ZEC that will pull the stream will receive it in multicast. By default Zixi Broadcaster is configured to allow transparent fallback to unicast if it is out of the LAN. Requires enabling Multicast Pull in the Settings.
Multicast-Only (for multicast enabled)	Selecting this checkbox will force the transmission of this stream only in multicast.
