The Australian Greens warn the country's five community television stations still face an uncertain future, despite the Senate today voting to support a compulsory switch to digital television by 2013.

"While the government says the switch to digital television will give consumers more choice, consumers will have less choice if community television stations are left out," said Greens Communications Spokesperson, Senator Scott Ludlam.

From 2013 all television stations will be required to broadcast in digital format and consumers will be required to purchase digital televisions or set-top conversion boxes. Community television stations will not have access to the technology necessary for the change without government assistance.

"Community television reflects the diversity of the Australian people and it brings diversity to an industry that is otherwise dominated by a few big players. It also provides a vital industry training ground."

"While I understand there is no easy road to digital transmission for community television, the Government needs to provide specific information on how it will ensure the survival of community television in the digital age. As things currently stand, there's a risk the digital revolution could mean pulling the plug on community TV."

"Community television's been a fundamental part of the history of television in Australia. It's crucial that it's part of the future of television as well," said Senator Ludlam.

A further 650 self help analog TV transmission sites, accommodating about 2,400 analog TV transmitters , could be affected by the digital switch.
