Implementation Challenges and Synergistic Benefits of DVB-S2 & DVB-RCS

Advantech believes that the combined use of DVB-S2 and DVB-RCS technologies, plus complementary technologies such as Ka band satellites, can produce a very low cost broadband delivery platform for both broadcast and interactive services. A return channel is rapidly becoming mandatory to serve both the needs of the content provider and to enable delivery optimisations (such as adaptive coding and modulation). DVB-RCS was designed as a natural solution and can be overlaid on traditional broadcast services. This paper discusses the specific implementation challenges that are presented when combining use of the two standards, and the benefits that can be achieved in practice, based on our real-world experience
