--- title: Adding UDP Outputs slug: zixi-broadcaster-v18/adding-udp-outputs docTags: createdAt: 2024-12-26T15:05:02.925Z --- This enables the Broadcaster to send a UDP stream. The UDP stream is not protected by the Zixi protocol. The UDP streams can be one of the following types: - UDP – plain UDP - RTP – Real-Time Transport Protocol - RTP + SMPTE 2022 FEC - SMPTE 2022 standard with Forward Error Correction **To Create a UDP Output:** ::::WorkflowBlock :::WorkflowBlockItem In the Zixi Broadcaster Outputs page, click **New Output**. The New output window is displayed ![](https://api.archbee.com/api/optimize/mzxtTQEvCNIdUNgF2kuwJ/k4aoo8ru_S0IF7xsSuBy9_image.png) ::: :::WorkflowBlockItem Type in the unique identifier for this output in the **Output Name**. ::: :::WorkflowBlockItem Select an **Input Stream** to be made available on this output from the drop-down list. ::: :::WorkflowBlockItem Select the Show in Matrix check box to display this stream in the Matrix (see [Using the Matrix](docId\:KyKY08NFFT6yGIZiGnhQ5) ). Default: Selected. ::: :::WorkflowBlockItem Select **UDP**. ::: :::WorkflowBlockItem Specify the **Output parameters** (see Output Stream Parameters Table below). ::: :::WorkflowBlockItem In the **Host** field, specify the IP address or URL of the stream destination. ::: :::WorkflowBlockItem In the **Port** field, specify the port of the destination. ::: :::WorkflowBlockItem If you want to specify **Billing Codes** to identify and differentiate traffic on a Zixi Broadcaster for billing purposes, select this checkbox (see Output Stream Parameters Table below) ::: :::WorkflowBlockItem If you want to remux the stream to CBR (used for professional IRDs) in order to avoid bandwidth waste or add NULL packets and adjust the stream clock (PCR) in order to make the stream CBR, select **Remultiplex/Pad** and configure the respective parameters (see Output Stream Parameters Table). ::: :::WorkflowBlockItem Click **OK**. ::: :::: ## Output Stream Parameters Table | **Parameter** | **Description** | | ----------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Output Parameters** |
| | **Host** | Specify the destination IP address or URL. | | **Port** | Specify the target UDP port. | | **TTL** | Specify the time-to-live (TTL). Used mainly to limit the range (or “scope”) of a multicast transmission. Leaving it as blank uses the default value specified by the operating system. | | **204B TS Packet** | Enable this option if the stream has an MPEG-TS that uses 204 bytes packets. This will allow the UDP packets to be allign with MPEG-TS packets. | | **Smoothing \[mms]** | Enables transmission of the output at the correct rate. Required when the receiving device is sensitive and can’t lock on to the stream (in such a case, the recommended latency is 100 - 1000 ms). | | **RTP** | Enables use of the Real-time Transport Protocol. | | **SMPTE 2022 FEC:** | Disables the FEC or specifies the type of FEC matrix to D1/ D2.
This setting can be modified without interrupting an existing stream.
In the SMPTE-2022 FEC standard, 1-D and 2-D parity codes are systematic FEC codes of decent complexity that provide protection against bursty or random losses. To enable SMPTE-2022 FEC (Forward Error Correction) select one of the following parity options from the drop-down menu:
- **1D **(single dimension FEC) - SMPTE-2022 1D can fix a problem in ONE packet per row. This means that the number of rows specified should consider the packet loss rate- the shorter the row, the more error resilience can be achieved on the expense of bitrate level. However, longer rows increase the delay that the FEC will add. It is recommended to select this option when the packet loss is sporadic.
The stream will occupy the source port and two ports above it (e.g. if the source port is 8988, it will occupy 8990)
- **2D **- SMPTE-2022 2D uses a table of packets, which includes rows and columns. This option is more error resilient, but it increases the delay by (row\*column) packets and increases the bitrate with R+C packets per each table of R\*C packets. It is recommended to select this option when packet loss is bursty.
The stream it will occupy four ports above (e.g. if the source port is 8988, it will occupy 8992). | | **Bind to IP** | Select from the drop-down list the local IP address to be used for this Output, OR select *Any *to enable any IP to be used. | | **Local Port** | Specify from which local port to source the stream, if desired (instead of randomly chosen by the operating system). | | **Billing Codes** | Billing codes are used to identify and differentiate traffic on a Zixi Broadcaster for billing purposes. When a billing code is added to a Source or Target, Zixi can track the traffic on that Broadcaster input or output separately from other inputs and outputs on the same Broadcaster. Billing codes are created by Zixi personnel on the Zixi Customer Portal for a particular organization. | | **Billing Code** | Enter the billing code that corresponds to this stream. The relevant billing can be obtained from the organization that received the billing code from Zixi. | | **Billing password** | Enter the password that corresponds to this billing code. | | **Remultiplex/Pad** | Select this checkbox to enable remuxing from VBR MPEG-TS to MPEG-TS CBR (used for professional IRDs) or padding with null packets. | | **Mode** | Select one of the following:
- Pad – adds NULL packets and adjusts the stream clock (PCR) in order to make the stream CBR.
- Remultiplex - performs demux->mux and rebuilds the stream according to the below parameters. | | **Target bitrate \[kbps]** | Specify the CBR bitrate to target for the padded stream (Pad) or a re-multiplexed stream (remultiplex). | | **PCR interval \[ms]**
| Select the frequency at which Program Clock Reference is inserted into the outputs Transport stream. Default - 90. | | **Buffer Size \[ms]** | Specify maximal difference between DTS and PCR. relevant only for remultiplex mode. | | **No NULL Packets** | Select this option to re-multiplex the stream to CBR but remove the NULL packets in order to maintain low bitrate. | | **Enable Decryption** | Select this checkbox to decrypt an encrypted stream. | | **Decryption type** | If the stream has been encrypted, you can decrypt through the output by selecting this checkbox and specifying the type of encryption that was used.
Select **Automatic** to decrypt a stream that has been encrypted using **Automatic** encryption.
Only if the stream has not been encrypted, select **None** (default).
***Important Notice: if the stream has been encrypted you must decrypt it in the output.*** | | **Decryption key** | If the decryption type includes a key, enter the key to decrypt the stream during output. |
