Adding UDP Streams

This enables the Broadcaster to receive 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 Add a UDP Stream:

In the Zixi Broadcaster Navigation menu, click the Inputs tab.
In the Menu bar, click New Input. The Add a new input stream window is displayed.
Enter the unique Stream ID.

Note this must be identical (case sensitive) to the stream name configured in the Zixi Feeder.
Select the maximum concurrent connections to this stream from the Max. Outputs drop-down list. Default: Unlimited.
Select the Show in Matrix checkbox to display this stream in the Matrix (see Using the Matrix). Default: Selected.
Select UDP for the input stream.
Specify the Stream Parameters (see Input Streams Parameters Table).
If you want to Enable time shift, select this checkbox (see Input Streams Parameters Table).
If you want to Transmit as multicast, select this checkbox (see Input Streams Parameters Table).
If you want to configure the Recording Parameters, specify them in the respective fields (see Input Streams Parameters Table).
If you want to Enable encryption select this checkbox (see Input Streams Parameters Table).
Click OK.

The “Input added” message appears on the top of the screen. The UDP Stream from the Zixi Feeder is added to the Zixi Broadcaster and now appears in the list of streams available in the Zixi Broadcaster inputs UI.

Input Stream Parameters Table

Parameter	Description
Stream parameters
Port	Specify the port to listen on. This port must be open on all firewalls between the Zixi Broadcaster and other devices it is communicating with.
Multicast IP	If multicast, type the Multicast IP address (or leave blank in the case of Unicast).
SSM Source	Specify the source IP for a source-specific multicast.
Type	Select the appropriate protocol type from the drop-down list.
Bind to IP	Specify which of the local IP address should be used. Select one of the local IP addresses in the drop-down menu.
Max. bitrate [kbps]	Specify the maximum expected bitrate for memory allocation. Recommended: 2X the actual bitrate, which will prevent buffer overruns (especially with VBR streams). Default: 8000. Note – Overflows will typically occur when the Max Bitrate isn’t sufficient.
RIST	Select this checkbox to receive 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)
Enable time shift	Select this checkbox to record the stream content and broadcast it after the specified delay.
Maximum delay [hh:mm:ss] (for Time Shift enabled)	Specify the maximum time delay of this input.
Transmit as multicast	Select this checkbox to enable the transmission of this stream’s outputs as multicast. A Zixi receiver that will pull the stream will receive it in multicast. By default Zixi Broadcaster is configured to allow transparent fallback to unicast if it is out of the LAN. Requires enabling Multicast Pull in the Settings.
Multicast-Only (for multicast enabled)	Selecting this checkbox will force the transmission of this stream only in multicast.
Enable Encryption	Select this checkbox to encrypt the Input stream. For more information, see Encrypting an Input Stream in Zixi Broadcaster.
Encryption type (for Encryption enabled)	Specify the type of Encryption (AES 128/192/256).
Encryption key (for Encryption enabled)	Click Generate to generate an encryption key. The generated encryption key must be sent to the end-user to decipher the received encoded stream.
Recording parameters	Select this checkbox to customize the recording parameters.
Max recorded file duration [hours]	Specify the maximum time allotted for recording a video stream. Default: 2 hours
Keep recorded files for [hours]	Specify the maximum time for storing the recording.
Custom Path	Optionally specify a storage location for the recorded files that is relative to the root folder. This location bypasses the location specified as the root folder in the Settings > General screen.
File Name Template	Specify the file name pattern that Zixi will use to generate when saving the recorded content. A separate file will be generated for each recording up to the time specified in the Max recorded file duration parameter (see above). After this duration a new file will be generated. The file name pattern can include any string and up to five variables listed below. Only the %T=HH.MM.SS creation time is mandatory. You can change the order of these variables and add text as long as you maintain the legitimate structure of the file in Linux and Windows: %S=stream id - optional. %Y=year - optional %M=month - optional %D=day - optional %T=HH.MM.SS creation time - mandatory For example, the following pattern %Y_recording%T.ts will generate the following file name 2017_recording15:32:35.ts.
