DVB-S2 (Digital Video Broadcasting - Satellite - Second Generation) is a digital TV standard created to replace DVB-S. It was developed by the DVB Project in 2003 and approved by ETSI in 2005. DVB-S2 supports standard- and high-definition TV, interactive services like Internet access, and data distribution, and it can work with existing MPEG-2 transport streams.

The main improvements over DVB-S are better and more flexible modulation and coding (including options up to 32APSK) and a versatile IP‑based transport system for data and video streams. These changes let DVB-S2 send more data in the same satellite bandwidth and power, making HDTV possible in the same bandwidth that used to carry SDTV with DVB-S. An optional extension, DVB-S2X, was published in 2014 with further improvements.

DVB-S2 is intended for home reception, professional satellite links (such as satellite news gathering), and data services. However, many devices still use DVB-S, so upgrading receivers or set-top boxes takes time. Patents related to DVB-S2 are managed by Sisvel.
