DVB-T stands for Digital Video Broadcasting via Terrestrial radio (i.e. This is Digital Video Broadcasting for broadcasting of Digital TV via terrestrial Antenna (indoor / roof).
DVB-T transmissions have already started in some countries (UK, Australia, Germany, Finland, Italy, France, Spain) (DK started 31 March-06, DR1, DR2, TV2). France is due to begin transmitting Pay Per View broadcasts in September 2005 (in MPEG4).
Depending on the Transmission Mode about 15MBit can get transmitted per Transponder (Frequency). This is enough for one HDTV channel or 4-5 Standard Definition TV channels. Multiple channels can be organized in Bouquets (a bunch of services by a particular Service Provider).
Tip
- Crazy as it may sound, if you find that video and audio sometimes freeze (and there are no error messages in /var/log/messages), your aerial signal may be too weak. A signal booster made a significant difference in my setup (Hauppauge Nova-T (Conexant) + Avermedia 771 DVB-T, 2.6.13-rc7 + dvb kernel patches from CVS)
