Feature Descriptions
MDM9000 Satellite Modem
16.18.2.6 Global Protection or Protection per Stream
DVB-S2 and DVB-S2X allows the transmission of several streams over satellite at the same time.
The different streams are all encapsulated in baseband frames and each stream is linked to a
different input stream identifier or ISI.
The ISI-values are used to separate all streams again at the reception site.
The AES encryption mechanism can work in two different modes:
• The first mode is called the global protection mode. In this mode, all different streams are
encrypted with the same content key. One pair of odd and even content keys or one pair of odd
and even encrypted content keys can be entered in the MDM6000.
Navigate to:
MDM6000 > Modulator >> AES Configuration Table
• The second mode is called protection per stream. In this mode, all different streams are
encrypted with a different content key. This means that different sets of content keys must be
entered in the modulator for each different stream that needs to be encrypted.
The following picture shows that the parameter Global Encryption is disabled.
This means that protection per stream can be enabled.
