Configure the Multiplexer component (Mux and encryption)

The following sections explain the basic configuration for the Multiplexer component. For advanced configuration, especially BISS-CA output transport stream, see Configuring a BISS-CA output transport stream.

To configure the Multiplexer, follow these steps:

1. Click the icon next to the Multiplexer component within the CE1 feed. The Multiplexer settings open.

   

2. From the Stream processing tab, you can see that a service has already been created. Select this service.

3. Go to the Properties > Output section and enter a service name.

Configure the Mux

To configure the Mux, follow these steps:

1. From the Stream Processing tab, click Transport stream.

2. Go to the Properties > Mux sub-tab:

   1. Check the Total Bitrate. If needed, you can modify it.
   2. To minimize the delay through the chain, set the following parameters in the Advanced settings section:
      • Input jitter buffer latency to 40 ms
      • Scrambling latency to 10 ms

3. From the Properties > Output sub-tab, check the pre-defined parameters.

4. Click Save and continue to save your changes.

Configure the encryption (scrambling)

To configure the encryption, follow these steps:

1. Go to the Scrambling tab:

   • Drag and drop the service under the Scrambling Groups tree.
   • Click the scrambling group to configure the encryption parameters as required. Some parameters appear in the Advanced settings.
   ⚠️

   Please beware of the following limitations when configuring BISS-CA:

   • BISS-CA Period to Play the session Key must be set to greater or equal to 60 seconds.
   • BISS-CA To ensure interoperability with RX8200, the encoder needs to set Additional Descrambler Delay to 60 seconds.
   • BISS-CA timings are not accurate - when session word and session key change at same time.
   • BISS-CA The session Word Period needs to be >= Additional Descrambler Delay.

2. Click Save and exit to save and finalize your service configuration.
