Gaelic communities and creative groups have been asked to join an "online conversation" on plans for a dedicated digital television channel for Gaelic.
The plan is already subject to a public value test
The Gaelic Digital Service is to be run as a partnership between BBC Scotland and Seirbheis nam Meadhanan Gàidhlig (Gaelic Media Service).
The online discussion started on Thursday at www.gms.org.uk
The BBC Trust has begun a public value test and independent regulator Ofcom has launched a market value assessment.
Seirbheis nam Meadhanan Gàidhlig said it hoped to involve Scotland's creative industries including programme producers, writers, directors and designers in the debate.
Chief executive Donald Campbell said: "We are at a crucial stage for the new Gaelic digital service.
"It is vital that we engage directly with people who will contribute to the new service, from the Gaelic community, the independent production sector and the wider creative industries in Scotland.
"They will all have a key role to play in this exciting new development for Gaelic language and culture and I look forward to a lively and interesting discussion over the coming weeks."
It is hoped the service will be on air by March 2008.
Archie Maclean, chief executive of Comunn na Gaidhlig (Gaelic Development Agency), said the channel may start with two to three hours of programmes which could be extended later.
