The DVB-S2 ad-hoc group of the TM was tasked with developing a
successor to the DVB-S standard (EN 300 421) and DVB-DSNG
standard (EN 301210), that could be introduced for new services and allow
for a long-term migration.
The primary objective of the new specification was to enable delivery
of a significantly higher data rate (e.g. 30%) in a given transponder
bandwidth than the current DVB-S standard.
Three satellite application areas were considered:
- Video and audio broadcasting (including a backwards-compatible
mode, allowing old DVB-S receivers to decode at least part of the
transmitted bouquet).
- Interactive services (direct path), such as internet access, for the consumer market.
- Professional links (SNG, contribution, internet trunking).
DVB-S2 was published as EN 302 307 by ETSI in March 2005.
