TNS said that an initial 6,500 digital satellite TV households in New Zealand would be connected to a newly created viewing panel that will be managed and recruited by the company, and connected to the NDS Audience Measurement System.
Data collected from the NDS software will be used to develop a better understanding of enhanced TV viewing habits, EPG usage and interactive ad popularity.
Sky Television said the trial would also enable it to analyse viewing habits and ensure customers see more of the programmes they like.
The NDS software has been designed to collect and analyse viewing data, which will initially focus on data relating to all satellite channels watched by households participating in the test.
TNS is responsible for the design, recruitment and maintenance of the viewing panel and the processing of data received.
John Fellet, chief executive of Sky Television, said: "By working with NDS and TNS on the Audience Measurement System, we will be able to further understand our subscribers' viewing habits and therefore provide more of what they want."
