Digital transmission means clearer pictures and sound for viewers.
In comparison to analogue, a digital system provides broadcasters the capacity to bring to viewers a multiplicity of channels that cater to all tastes and demands. Enhanced and interactive programming to enrich the individual viewing experience can also be delivered, including services such as e-mail and Internet access through your television set. TelstraSaturn is expanding its network services into digital as part of its national expansion plans. TVNZ has been examining digital options over the last couple of years. Upgrading to digital infrastructure is a significant technical and economic exercise.
