A Brief Look at Terrestrial Television
Terrestrial broadcast is the traditional way of watching TV programs via a roof top or indoor
antenna. It is commonly known as Analogue TV.
In recent years “Digital Terrestrial TV” has been introduced in several countries. It offers improved
quality via a noise free crisp picture quality and CD like crystal clear sound in addition to a
convenient “EPG” (Electronic Program Guide) and 16:9 video format.
Traditional analogue TV transmissions require one radio frequency channel per TV channel.
Whereas an analog terrestrial video program requires 8MHz bandwidth, a digital terrestrial video
program only requires 1 to 2 MHz bandwidth. In other words, four to eight video programs or
multiple audio and data channels can be transmitted in place of one analog program. The
broadcasters can therefore now increase the number of programs and services they offer with a
minimal increase in cost. Furthermore, since the signals are transmitted in digital format, there is
absolutely no quality loss between transmission and reception as is the case with analog mode.
digital format also allows for transmission of high speed Internet and other data
Digital TV signals are transmitted in Free-to-Air (FTA) mode which can be received by anyone with
an MPEG 2 – DVB compliant digital terrestrial receiver such as the PX-TUDI-01.
The PX-TUDI-01 Tuner is fully MPEG 2 / DVB-T (digital video broadcast-terrestrial) compliant,
delivering crystal-sharp video and excellent sound. It supports a signal range from 51 to 858 MHz,
and can be easily programmed for all the channels within the VHF/UHF frequency spectrum. It can
receive major and sub-channels containing both video and audio programs.
