The Australian Communications & Media Authority (ACMA), the communications watchdog, is waiting for an SBS report on the impact of 3D TV trial broadcasts of rugby league and football games from last May.

Donald Robertson, an ACMA spokesman, said that the regulator received a report from Channel Nine regarding the first 3D trial that the network conducted earlier this year in conjunction with SBS.

Channel Nine announced last week that it was planning on airing another 3D broadcast. However, the network would need another trial license to broadcast the National Rugby League grand final on October 3.

"Nine is thrilled to once again bring rugby league fans the most technologically advanced way to watch their game," said David Gyngell, the company's chief.

The ACMA had publicly rebuked the network for circulating a statement wherein it announced plans to broadcast the National Rugby League grand final in 3D.

"Providing a report on consumer, reception, interference and technical issues was a condition of the previous 3D TV trial license... The ACMA has indicated to Nine that no further trial licences will be issued before the report is received and considered," an ACMA statement read.

Nine released a second statement saying that it "did not seek to pre-empt a decision from ACMA regarding the issue of a licence to broadcast the 2010 NRL grand final in 3D in October" and it was "actively working with ACMA to secure the necessary licences".
