The shift to digital brings several advantages including better image and sound quality as well as more efficient use of spectrum that will open the door to new telecom services. It also requires those relying on over-the-air signals to obtain a digital converter box to convert the digital signal back to analog.
Contrary to popular belief, many Canadians still rely on over-the-air signals. In its latest update on the transition, the Canadian Radio-television and Telecommunications Commission estimated that up to 857,000 households in larger markets do not subscribe to either cable or satellite. On top of those households, tens of thousands of rural households also depend upon over-the-air signals.
