History - Evolution of Digital Television in New Zealand

JDA played a central role in the creation of New Zealand's first private television network, TV3

JDA provided the transmission testimony for the tribunal hearings, which enabled TV3 to win the first warrant for private television in New Zealand. JDA were also major contributors to the innovative development of the VHF channel plan implemented for the three networks: TV One, TV2 and TV3.

JDA then discovered it was possible to fit a fourth television network, TV4 (now "BRAVO") into the VHF channel plan, and after providing appropriate resolution of the interference analysis, JDA satisfied the Ministry that the new plan was feasible. As a result, TV4 was created with minimal acquisition of any new spectrum.

JDA use custom software to predict coverage from arbitrary transmission sites using a digital terrain database and sophisticated diffraction algorithms. JDA used this software extensively for TV3 and TV4 design, to select appropriate locations to achieve the best coverage possible with the minimum number of sites.

We have also been involved in several TVNZ special projects and the expansion of the Maori TV and Prime TV networks. Our independence allows us to offer complete, confidential services to any client.
