DVB‑S is the first‑generation standard for digital satellite TV broadcasting. It was introduced in the mid‑1990s and defines how MPEG‑2 transport streams are transmitted over 11/12 GHzGigaHertz (GHz) 10^9 Hz satellite channels. It uses QPSKQuadrature Phase-Shift Keying (2 bits per symbol) modulation and a combination of convolutional and Reed‑Solomon coding to ensure reliable transmission. It became widely adopted by satellite operators for TV and data services.
DVB‑S2 (Digital Video Broadcasting – Satellite, Second Generation) DVB‑S2 is the second‑generation standard designed to improve efficiency, flexibility, and performance. It introduces more advanced modulation schemes such as QPSKQuadrature Phase-Shift Keying (2 bits per symbol), 8PSK8-Phase Phase-Shift Keying (3 bits per symbol), 16APSK, and 32APSK, along with stronger LDPC/BCH error correction. DVB‑S2 supports a wide range of applications including broadcasting, interactive services, and news gathering, offering significantly better spectral efficiency compared to DVB‑S.
