Cinegy Stream Switcher channel represents a configuration of Cinegy Air with the following settings: two playout servers (main and backup sources) receive RTP streams and the main playout server performs the broadcast. In case of main playout server failure the broadcast is switched to the backup playout server. Switching to backup source is performed according to the specified alerts settings.



To launch this application, go to Start > All Programs > Cinegy > Stream Switcher Control or use the corresponding desktop shortcut. The following window will open:

  • Stream Switcher server – specifies the computer where Cinegy Stream Switcher service is installed. Enter the computer name via the keyboard or use the "…​" button and select it from the list of available computers in the network:

  • Port – specifies the Cinegy Stream Switcher control port.

    This value should be equal to the "Stream Switcher control port" value set in Cinegy Stream Switcher Configurator. Otherwise, connection will not be established.

Use the "Disconnect" button to disconnect from Cinegy Stream Switcher service. The button will turn into "Connect" button. Press this button to establish connection.

The connection status is shown in the "Status" field.

Stream Settings

To add a new channel to the list, press the Button_add button; the following "Stream Settings" window will open:

Incorrectly filled in or empty fields are highlighted with a red bounding box. The "OK" button is grayed out and the settings cannot be applied unless all values are valid.

Here define the following settings:

  • Stream name – specifies the channel name.

  • Main source – specifies the source stream from the master playout server. Enter the address in the following form: rtp://<IP>:<port>. Alternatively, you can use the "…​" button to select the desired stream.

    Refer to the Stream Selection paragraph for detailed information about stream selection.
  • Backup source – specifies the source stream from the slave playout server.

  • Output – specifies the output stream.

  • Max UDP delay – defines the maximum delay time of UDP packets in milliseconds. If the actual UDP packets delay exceeds this value, the stream is considered to be absent.

  • Max RTP packets loss – defines the maximum number of missing RTP packets allowed per stream.

Having configured the necessary parameters, the window will look as follows:


Stream Selection

The main and backup source channels can be defined manually via the keyboard or using the corresponding "…​" buttons. To be able to browse streams, Cinegy Route Browser should be installed on your machine.

Cinegy Route Browser is one of the Cinegy Route software components. Refer to the Cinegy Route Browser article in the Cinegy Route Manual for details.

Press the "…​" button, the following window will open:


Select the stream from the "Physical Sources" tree and press the "OK" button.


The "Alerts" tab allows you to set up the actions in case of particular problems with the stream:


Select the desired alert in the right column and in the corresponding "Action" drop-down list select the action that will be performed:

  • Nothing – no action is performed;

  • Notify – the SNMP trap is sent to the preconfigured destination;

  • Switch to backup – the stream is switched from master to slave playout server.

The most common configuration is as follows:


Switching to backup source is performed in case of stream absence and when the number of missing/dropped packets per stream is exceeded. The boundary parameters for these two alerts are set up on the "Settings" tab. The other alerts are DVB tables data specific and can be configured according to your needs.

Please refer to the DVB standard definition for details about DVB parameters.

Having configured all the necessary settings press the "OK" button to apply them. The configured channel will be added to the "Channels" list.
