The OTTtv World Summit kicks off in London this morning, with a day dedicated to 4K, and we have a special Irdeto interview with speaker Godert Burghard for you on the question of 4K content protection.

If you were unable to make it today but still want to go later this week, it’s not too late to book. Click here to do so. 

IP&TV News: What new security challenges does the emergence of 4K/UHD present?

Godert Burghard: The big security challenge comes from the fact that the whole production and distribution processes are much more costly than for example HD or SD content.

It’s the same when it comes to bandwidth consumption, because as you can imagine a 4K/UHD movie consumes much more bandwidth than an HD movie, especially if it’s live.

How have the movie studios reacted to this prospective price rise?

They’ve joined forces and said ‘ok, we need to really protect this so we’re going to bring out more aggressive security specifications.’

And what are these?

They’ve put forward a consolidated set of requirements concerning the security measures for 4K UHD content. These concern quality (Next Generation Video v1.0) and security Enhanced Content Protection v1.1). On the quality side it’s all about resolution, frame rates (24-120) and High Dynamic Range.

On the security side – Irdeto’s core focus, of course – it relates to DRM, Platform Security and End-to-end system security. To start with the first, DRM: This includes encryption and attack resistance, the revocation and renewal of DRM keys, and output signalling.

The other aspect concerns the platform specification, where the specifications demand the implementation of Hardware Root of trust, Secure Computation, platform encryption and the secure Media Pipeline and Link Control..

The last one is the end-to-end system specification, which is the certification that we at Irdeto employ with regards to the suppliers we use in our solutions. Another aspect is Watermarking to identify where a breach originated and an approach to Breach Responses. If you comply with these specifications it is likely the studios will grant you the licences for theur 4K UHD content which can help the operator to better serve its customers.

What will you be focused on finding out more about at the OTTtv World Summit?

The biggest thing in the market is Ultra HD and the challenges that it brings. Other than this the show for me is about finding the latest developments in business models – monetization strategies and what else is  new in the ever changing TV landscape.
