DVB-T (Digital Video Broadcasting – Terrestrial) allows the viewers to watch more channels with better quality of sound and picture compared to analog television broadcasting.
In analog television broadcasting, each program is aired on a separate frequency. In DVB-T, one frequency (one multiplex) could carry between 6 and 10 SD MPEG-4 TV programs – depending on quality and format.
Digital terrestrial television is free for the viewers. In order to receive DVB-T signal, they need to have either a TV set with a built-in DVB-T tuner or a set-top-box. The tuner (set-top-box) has to support MPEG-4, H.264 AVC format. MPEG-2 set-top-boxes could not be used for decoding of DVB-T signal in Bulgaria.
Most of the countries in the world have already switched to digital terrestrial broadcasting or are in a transition period.
The transition from analog to digital terrestrial broadcasting in Bulgaria took place in two stages. The first stage began on 01.03.2013 – digital and analog TV programs were aired simultaneously for 7 months. On 30.09.2013 began the second stage of the process – all analog TV transmitters were shut down for good and from then on the terrestrial TV broadcasting in Bulgaria has been digital only.
