BT Vision is putting "significant investment" into new applications including gaming and teleshopping, chief executive Dan Marks has said.

“Over the next 12 months we are going to make a significant investment in applications that can sit on the platform and be interrogated by the viewer allowing them to do those things," he told a conference in London.

“We’re going to build a personalised TV service that brings together the things you do in your study on a PC with some of the things that you do in the living room."

Marks added: "We are able to hold a lot of content and open up a TV connection between home and the world. Once you do that television changes."

The hybrid DSL-digital terrestrial television service uses Microsoft's Mediaroom system. At last month's Digital Television Group summit Microsoft's Gavin McLauchlan said it was pressing its partners to develop interactive services and links between TVs, computers and other hardware.
