To Create a UDP Output:
- In the Zixi Broadcaster Outputs page, click
. The New output window is displayed.
- Type in the unique identifier for this output in the Output Name.
- Select an Input Stream to be made available on this output from the drop-down list.
- Select the Show in Matrix check box to display this stream in the Matrix (see Using the Matrix). Default: Selected.
- Select UDP.
- Specify the Output parameters (see Output Stream Parameters Table).
- In the Host field, specify the IP address or URL of the stream destination.
- In the Port field, specify the port of the destination.
- If you want to remux the stream to CBR (used for professional IRDs) in order to avoid bandwidth waste, select Remuxing and configure the respective parameters (see Output Stream Parameters Table).
- Click OK.

| 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. |
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. |
Bind to IP | Specify the local IP address to use in the output. The IP address can be also sourced from any active NIC. Select the local IP from the drop-down menu. |
Local Port | Specify from which local port to source the stream, if desired (instead of randomly chosen by the operating system). |
Don’t Fragment | Select this option if you do not want to fragment IP packets in a stream. |
| Remuxing | Select this checkbox to enable remuxing from VBR MPEG-TS to MPEG-TS CBR (used for professional IRDs). |
| Remux to bitrate [kbps]: | Specify the CBR bitrate to target for a remuxed stream. |
| Buffer Size [ms] | Specify the size of the buffer that will be used for the remixing. A larger buffer increases the quality, but also increases latency. |
| 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 ecryption 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. |
| Enable IFB/Talkback | Select this checkbox to enable IFB/Talkback for one-way communication from the director or assistant director to on-air talent or a remote location. Selecting the checkbox allows the decoder with a Zixi Receiver to send audio back to the encoder with a Zixi Feeder. This offers the ability to, for example, give audio feedback to the camera operator. |
| Port | The port that will be used to send the audio feedback. |
