What is the digital switch over (DSO)?
The Digital Switchover was a New Zealand government initiative to transition from analogue TV transmission to digital TV transmission.
Compared to analogue TV transmission, digital transmission is a makes more efficient use of radio frequencies available, enabling HD broadcasts and freeing up frequency bandwidth for other uses, such as for telecommunications.
From September 2012 to December 2013, the analogue TV signals in New Zealand were switched off throughout New Zealand, replaced by digital TV transmission.
The process was managed by a team made up of government leaders and industry experts, with Freeview providing the free-to-air digital TV platform for New Zealand.
