Digital Video Broadcasting - Terrestrial (DVB-T)

Definition - What does Digital Video Broadcasting - Terrestrial (DVB-T) mean?

Digital Video Broadcasting - Terrestrial (DVB-T) is a standard set in 1997 and put into use in 1998 for the transmission of digital terrestrial television (DTT). DVB-T is able to transmit different kinds of data, including compressed digital information, digital audio, digital video, Moving Picture Experts Group (MPEG) and other data with codec modulation. DVB-T provides an advanced method of transmission compared to the previous analog transmission.

Techopedia explains Digital Video Broadcasting - Terrestrial (DVB-T)

In the present age, television transmissions are broadcast from towers and then beamed to homes via receivers passing through satellites. This provides easy and reliable satellite-based transmission. But this is not the only method used for television broadcast.

Many countries have implemented DVB-T, which has reformed into many other standards such as DVB-H and DVB-T2.

The working mechanism of DVB-T involves the following:

  • Digital data is transmitted in discrete blocks at symbol rate.
  • DVB-T allows for the handling of multipath scenarios through the orthogonal-frequency-division-multiplexing technique.
  • Single-frequency network operation is also used by DVB-T, where two or more transmitters may carry the same data at the same frequency.

DVB-T has many features that play an active role in operational management. Some of these features include:

  • Splitter
  • External encoder
  • External interleaver
  • Internal encoder
  • Mapper
  • Frame adaption
  • Pilot and transmission parameters signals
