ParameterDescription
Output Parameters
Profile

Select one of the following RIST profiles that matches the input stream:

  • Simple Profile (default)
  • Main Profile
Type (Main Profile)

Select the stream direction:

  • Push
  • Pull
HostSpecify the destination IP address or URL of the host to which the steam will be pushed.
PortSpecify 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).

SMPTE-2022 FEC

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.

Info

This setting can be modified without interrupting an existing stream.

To enable SMPTE-2022 FEC (Forward Error Correction) select one of the following parity options from the drop-down menu:

  • 1D - 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 will occupy four ports above (e.g. if the source port is 8988, it will occupy 8992).
Bind to IPSelect from the drop-down list the local IP address to be used for this Input, 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).

RIST main profile parameters

Use DTLS

Select this option to connect using DTLS, which offers authentication and encryption.

Ignore TLS certificate errors

Select this option when streaming to a trusted server that does not have a valid certificate. When this option is selected, Zixi Broadcaster will ignore the TLS certificate errors and transmit the stream to its destination.

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/PadSelect 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).

Enable DecryptionSelect 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 keyIf the decryption type includes a key, enter the key to decrypt the stream during output.
Enable IFB/TalkbackSelect 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.
PortThe port that will be used to send the audio feedback.
