The Government has committed to help install and use the equipment to convert one television set to digital, which will be free to the over-75s and disabled people who receive income-related benefits.
Older and disabled people who do not receive such benefits will pay a subsidised fee of £40.
The funding will come entirely from the forthcoming TV licence fee settlement, Jowell added.
The announcement was made on the day the Digital Switchover (Disclosure of Information) Bill received its second reading in the House of Commons.
The Bill proposes that the BBC receives social security and war pensions information during digital switchover, which would then be used to identify people who are eligible for support under the scheme.
Starting in Whitehaven at the end of 2007 and the rest of Borders in 2008, digital switchover will roll out in the UK by ITV region until the programme is completed in Northern Ireland in 2012.
