Abstract: Analogue terrestrial television has been in existence since the 1940s but was rendered obsolete due to advancement in technology and its inefficient use of the frequency spectrum which is a limited resource. Analogue Terrestrial Television is said to use one frequency to carry one programme channel while Digital Terrestrial Television (DTT) can use one frequency to carry multiple programme channels. What this means is that Digital Terrestrial Television allows for transmission of many television programmes using one frequency channel and at lower cost. So what is Digital Broadcasting Migration?
