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:
- 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 specify Billing Codes to identify and differentiate traffic on a Zixi Broadcaster for billing purposes, select this checkbox (see Output Stream Parameters Table below)
- If you want to remux the stream to CBR (used for professional IRDs) in order to avoid bandwidth waste , select Remuxing 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).
- Click OK.

| Parameter | Description | ||||
|---|---|---|---|---|---|
| Output Parameters | |||||
Host | Specify the destination IP address or URL of this output. | ||||
Port | Specify the target UDP port to listen on. | ||||
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 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, or any one which can be sourced from any active NIC. Select the local IP from the drop-down menu
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:
| ||
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). | Don’t Fragment | Select this option if you do not want to fragment IP packets in a | ||
| 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:
| ||||
| Target bitrate [kbps] | Specify the CBR bitrate to target for the padded stream (Pad) or a re-multiplexed stream (remultiplex). | ||||
| Remux to bitrate [kbps] | Specify the CBR bitrate to target for a remuxed stream. | ||||
| 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 ecryption 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. | ||||
Remuxing | Enables remuxing to CBR (used for professional IRDs). | ||||
Remux to bitrate [kbps]: | Specify the CBR bitrate to target for a remuxed stream. |
| 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. |
