This enables the Broadcaster to receive a UDP stream. The UDP stream is not protected by the Zixi protocol.

To Add a UDP Stream:

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

  3. Enter the unique Stream I.D.

    Note this must be identical (case sensitive) to the stream name configured in the ZiXi Feeder.

  4. Select  the maximum concurrent connections to this stream from the Max. Outputs drop-down list. Default: Unlimited.
  5. Select the Show in Matrix check box to display this stream in the Matrix (see Using the Matrix on page 45). Default: Selected.
  6. Select UDP for the input stream.
  7. Specify the Stream Parameters (see Input Streams Parameters Table).
  8. If you want to Enable time shift, select this checkbox (see Input Streams Parameters Table).
  9. If you want to Transmit as multicast, select this checkbox (see Input Streams Parameters Table).
  10. If you want to configure the Recording Parameters, specify them in the respective fields (see Input Streams Parameters Table).
  11. If you want to Enable encryption select this checkbox (see Input Streams Parameters Table).
  12. 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

ParameterDescription
Stream ID

Specifies the unique identifier for this stream.

Max OutputsSpecifies the maximum number of allowed outputs. Default: Unlimited.
Show in MatrixShow input in matrix.
Stream parameters
PortSpecifies 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

Specifies the source IP for a source-specific multicast.

Type

Select the appropriate protocol type from the drop-down list.

Bind to IP

Specifies which of the local IP address should be used. Select one of the local IP addresses in the drop-down menu.

Max. bitrate [kbps]

Specifies 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.
Enable time shiftEnables a delayed transmission of this input.
Maximum delay [hh:mm:ss]

Specifies the maximum time delay of this input.

Transmit as multicast

Enables transmission of this stream’s outputs as multicasts. A ZiXi receiver will receive it in multicast (unless it is out of the LAN in which case it will receive as unicast). You can also force Multicast only outputs. Requires enabling Multicast Pull in the Settings.

Multicast-OnlyIf desired, specify multicast only outputs.
Enable Encryption

Encryption type


Specify the type of Encryption (AES 128/192/256). Selection of Automatic will generate an AES 256 bit encryption and exchange it securely between the applications automatically. (for more information, see Encrypting an Input Stream in Zixi Broadcaster)

Encryption key

Click Generate and the encryption key for the input stream will appear in the adjacent text box. Send it to the end-user to decipher the received encoded stream.

Recording parameters

Max recorded file duration [hours]

Specifies the maximum time allotted for recording a video stream. Default: 2 hours

Keep recorded files for [hours]

Specifies the maximum time for storing the recording.
