Two new partners have joined Project Canvas, a scheme designed to deliver subscription-free, on-demand TV content to UK households via broadband.

Broadband provider TalkTalk and terrestrial broadcaster Channel 4 will now play an active role in the venture, joining existing participants BBC, ITV, Five and BT.

Subject to approval by the BBC Trust, the project will create a next-generation platform for Freeview and Freesat viewers.

Max Alexander, Senior Director for TV at TalkTalk, said the internet service provider had "led the way" in making the internet accessible "by championing value and building the most extensive network" in the UK.

"We're pleased to support Project Canvas and believe that it will be of great interest to our four million customers," he stated.

Gill Pritchard, Director of Strategy at Channel 4, claimed that IPTV is set to become the next generation of living-room television.

She added: "If Channel 4 is to continue to enhance its importance in a fully converged world, it is key to be part of driving Project Canvas."

TalkTalk claims to have created the UK's most advanced next-generation network, offering such services to more than 80 per cent of the UK population.
