Definition Edit

Digital terrestrial television (DTTV or DTT) is the technological evolution of broadcast television and advance from analog television, which broadcasts land-based (terrestrial) signals. The purposes of digital terrestrial television, similar to digital versus analogue in other platforms such as cable, satellite, and telecommunications, are reduced use of spectrum and more capacity than analogue, better-quality picture, and lower operating costs for broadcast and transmission after the initial upgrade costs.

A terrestrial implementation of digital television (DTV) technology uses aerial broadcasts to a conventional television antenna (or aerial) instead of a satellite dish or cable television connection.
