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_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.

1. Make sure at least one of the existing inputs has the Enable time shift setting selected.
2. In the Zixi Broadcaster ZEC Navigation menu, click the Inputs tab.the Inputs
3. In the Menu bar, click click New Input. The The Add a new input stream  window window is displayed.
4. Enter the unique unique Stream I.DID.
5. Select the maximum concurrent connections to this stream from the Max. Outputs the Outputs drop-down list. Default: Unlimited.
6. Select the the Show in Matrix checkbox check box to display this stream in the Matrix (see ZEC see Using the Matrix). Default: Selected.
7. Select  Delayed for Delayed for the input stream.

8. Specify the Stream Parameters (see Input Stream Parameters Table).
9. If you want to Transmit as multicast, select this checkbox (see Input Stream Parameters Table).
10. Click OK. The “Input added” message appears on the top of the screen. The Delayed Stream is added to the Zixi Broadcaster ZEC and now appears in the list of streams available in the  Zixi Broadcaster ZEC inputs UI.

    Input Stream Parameters Table

    Parameter	Description
    Stream parameters Parameters	The general stream settings.
    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.
    Transmit as multicast	Select this checkbox to enable the transmission of this stream’s outputs as multicast. A Zixi receiver that will pull the stream will receive it in multicast. By default Zixi Broadcaster ZEC 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 Multicast enabled)	If desired, specify multicast only outputs.
