SHAPING THE FUTURE OF SATELLITE COMMUNICATIONS
8.1.3.2 DVB-S2 Multi-Stream
A unique feature of DVB-S2 is the ability to carry different transport streams and/or
generic streams into separate baseband frames, on the same satellite carrier.
Each Baseband frame is identified with an Input Stream Identifier. A sequence of
DVB-S2 baseband frames with the same ISI number is called a DVB-S2 stream. A
satellite carrier that transports several DVB-S2 streams is said to operate in multi-
stream mode.
