Digital Video Broadcast: Systems and Implementations
2.1 Development of DVB Infrastructure
Terrestrial broadcasting has brought entertainment and media information to mass audiences around the world for nearly a century. In the last two decades, the demand for consumption of multimedia services anywhere anytime has increased greatly. Because the spectrum resource is limited, a new spectrum efficient broadcasting technology is required to meet this demand. Digital broadcast technologies, such as the European Digital Video Broadcast Terrestrial (DVB-T), moved terrestrial broadcast into the digital age. While analog broadcast can only deliver one programme per channel, digital broadcast namely DVB-T allows multiprogramme broadcasting where 2 to 4 standard definition TV (SDTV) programmes can be transmitted with time division multiplexing in a single 8 MHz channel. The bandwidth of DVB-T (from 12 to 24 Mbit/s) can be allocated to offer different TV qualities, such as enhanced definition television (EDTV, requiring about 10 to 12 Mbit/s per...
