DVB (digital video broadcasting) was developed in the 1990s by a consortium of program providers, device manufacturers, network operators and authorities in order to offer more TV channels with better definition (HDTV) as well as other services. The following variants exist: DVB-S / DVB-S2 (satellite), DVB-C (cable), DVB-T (terrestrial) and DVB-H (handheld). DVB is standardized by ETSI.
QPSK (DVB-S), 8-PSK or APSK (DVB-S2), 64-QAM or 256-QAM (DVB-C), COFDM with QPSK or 16-QAM or 64-QAM for individual carriers (DVB-T). COFDM systems use OFDM modulation with forward error correction.
