SYDNEY, NSW: The Australian Communications and Media Authority (ACMA) has now closed the free-to-air 3D broadcast channels, with the first trial period ending on 19 July 2010. During this period, ACMA allowed the free-to-air networks, especially Channel Nine and SBS, to transmit content outside their usual allowance. This was used primarily for the State of Origin and the 2010 World Cup.

Although ACMA has closed this limited trial period, it has indicated that subject to the receipt of feedback and the publishing of a report on this trial, it is considering re-opening the window at a later date.

“The ACMA is now considering applications for a further tranche of short-term free-to-air trials and more generally expects to release a paper in the next few months on the future of 3D trials,” said a spokesperson.

“This paper will address the likely demand for spectrum to further experiment with and test 3D technology.

“The paper will also address international developments in the standardisation of consumer equipment, as technical standards for 3D TV receivers have not yet been established.”

Future sporting events that have been rumoured to be shown in 3D include the AFL and NRL finals series and the Melbourne Cup.
