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
RIST protocol support – Zixi Broadcaster supports RIST streams from any compliant RIST device. Contact your Zixi representative to learn more about interoperability testing between Zixi Broadcaster and 3rd party devices. The RIST protocol can be enabled for any of the stream types mentioned above.

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 | 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. |
Bind to NIC | Select from the drop-down list the NIC to be used for this Output, OR select Any to enable any NIC to be used. |
Local Port | Specify from which local port to source the stream, if desired (instead of randomly chosen by the operating system). |
RIST | Select this checkbox to send RIST streams from any compliant RIST device. |
Max Latency [ms] | Specify the maximum latency of the stream in milliseconds. |
Remote Port | Specify the remote port in the RIST device. Default: 0 (any port) |
1.4 support | |
Compression | |
Fast Connect | |
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. |
