Question

What is the difference between DTT and DTH?

Answer 1

Digital Terrestrial Television (DTTV or DTT) is an implementation of digital technology to provide a greater number of channels and/or better quality of picture and sound using aerial broadcasts to a conventional antenna (or aerial) instead of a satellite dish or cable connection

The broadcasting of digital terrestrial transmissions has led to many countries planning to phase out existing analogue broadcasts.

The original concept of satellite television started over 50 years ago, direct to Home (DTH) satellite receivers were developed in the early 1980’s.

DTH offers better quality picture than cable TV and stereophonic sound effects. It reaches even those places where cable is not available. This service is also providing value-added services that include teletext, dual audio for channels, parental control, electronic programme guide and radio channels. DTT also provides such functions, but not at the same standard.

Main disadvantage of DTH is fading of the signal due to rains. Heavy rains may result into outage for a few minutes in the DTH signal
