DVB-T systems

The DVB-T (Digital Video Broadcasting Terrestrial) is a digital TV standard broadcasted by terrestrial transmitters. Digital audio and video streams are sent by means of COFDM (Coded OFDM) transmission. Audio/video compression is done in MPEG-2 and H.264 standards.

Digital terrestrial TV allows sending in a single TV channel up to 7-8 TV channels, radio programs and additional multimedia services. A subscriber who has a terminal called STB (Set Top Box) or a TV set adapted to DVB-T signal reception can directly receive TV and radio programs and have an access to multimedia services. TV programs transmitted in the DVB-T standard can be received by old antenna systems and can offer the program broadcasters the following advantages:

• the increase of efficiency of frequency spectrum usage by transmitting digital multiplexes instead of single analog program transmission;
• the increase of efficiency of the terrestrial network thanks to re-use of the same frequency in transmitting areas in close vicinity (Single Frequency Network),
• substantial improvement of service quality thanks to digital transmission of TV and radio programs,
• additional services transmitted together with TV programs like EPG (Electronic Program Guide), Data/Video on Demand.
