Unallocated BSB spectrum known as Channel A and Channel B was previously reserved for digital television services such as a limited range of in-home broadcasting services and for mobile television services. However, the concept of Channel A and Channel B was discarded by the government as part of the policy review of the allocation and use of spectrum known as the digital dividend (spectrum to be vacated upon the switch-off of analog television).
In November 2009, the Minister for Broadband, Communications and the Digital Economy announced that, as part of a pathway to digitisation, unassigned spectrum previously known as Channel A would be allocated to community television in each mainland metropolitan market until analog switch-off in 2013. In June 2010 the Minister announced that the government had decided to release 126 MHz of BSB spectrum as a digital dividend. This announcement left the former Channel Bs available only for temporary use until the process of analog switch-off is completed.
The ACMA issued scientific licences using this temporarily available spectrum to a number of applicants in 2010. These licences authorised trials of 3D television in limited locations. In September 2010 the ACMA issued a discussion paper The future of temporary trials of 3D TV and other emerging technologies. This paper sought comment on the temporary use of Channel B spectrum until analog switch-off.
Any allocation of the former Channel A spectrum beyond the temporary allocation to community television in metropolitan areas is a policy matter for the government.

The Broadcasting and Switchover Policy Branch is the appropriate area. The switchboard number is (02) 6271 1000.
