Canvas sets out content protection approach

Project Canvas has published information on its content protection strategy, which the project said was 'designed to enable Canvas to support the widest possible range of content types for internet-connected TV audiences.'

According to Canvas, content providers can choose to make content available with no protection at all, or adopt transport encryption, file encryption, device authentication, or digital rights management (DRM). Conditional Access upgrade will also be possible for those who require it.

For providers of premium content or those requiring a subscription or download model, Canvas will support Marlin as the required DRM solution, at launch, which has been developed over the past five years by Intertrust, Panasonic, Philips, Samsung and Sony.

Anthony Rose, Chief Technology Officer, Project Canvas said: "Project Canvas has worked hard to account for the needs of all industry participants and ensure a rich and diverse TV viewing experience for consumers. We have also considered the submissions of key industry participants into the BBC Trust approval process.

Our content protection requirements have to cater for the widest possible number of content providers, including giving reassurance to those looking to support pay per view and subscription access to film. The industry is looking for a fully supported DRM solution, and Marlin will give content providers the best option at launch. Marlin is based on open standards, is already widely supported and is being increasingly deployed by the industry."

The publication of the Project Canvas Content Protection requirements add to the technical specification documents already made available to industry through the DTG with the most recent documents released on 30th June. Project Canvas plans to submit further technical documents on 30th July and 19th August.
