Ultra-HD, 3D without glasses, and some philosphy#dvbw13


The final session of DVB World examined Ultra-HD (4k) production situation today, via Peter Sykes from Sony.

Understanding the availability of programmes in Ultra-HD is critical to deciding when an Ultra-HD broadcast system will be needed. Sony have a set of 4k cameras now available, and an Ultra HD recording format XAVC (based on AVC), so the elements of Ultra-HD program making are ‘in place’, or at least available for purchasing. Sony also believes that shooting in Ultra-HD is a good policy even for HDTV, because the down converted material makes superb HDTV. Shooting in UHDTV also allows a sports producer to select high quality HD segments of the scene too. I’m sold – are you?

3DTV without glasses has been possible for some years, but has always been somewhat uncomfortable because head positions are constrained. Walt Husak explained the work done by Dolby in developing an auto-stereoscopic display making use of a 4k Ultra HD display. The 3D picture is made up of stripes of images, and a lenticular screen coating arranges for the eyes to see different pairs of images depending on head position. The result should be quite comfortable viewing of 3DTV without glasses. A really great feature here is that the same TV can be used for viewing Ultra-HD, or 3D without glasses with about HDTV quality. This should really sell well – do you agree?

In a final presentation, your blogger took the delegates through an analysis of ‘success factors’ needed for new media to succeed. They include a definite improvement in the user experience, affordability, desirable content, and easy use.  There are many more, and the factors may be different for different age, income groups, etc, but fundamentally any new system has to score highly in these four areas.

During the session, we asked delegates to vote on a number of issues. One was whether technical quality or user convenience is the more important success factor. The surprise was that most people thought convenience outweighs technical quality.

A slight majority thought that, eventually broadband will replace broadcasting – but this is obviously an issue we are nor sure about.

The conference closed with a short presentation by Phil Laven, among other things he pointed out that we may soon need to look more carefully at Wifi frequency allocations – there are obviously not enough of them, and much of the future will depend on using Wifi to bring TV to portable devices in the home.

Maybe that is for next year?

    Thanks a lot for this blog. I did not have a chance attend the event. But with your posts I can at least have a feeling of issues argued in the sessions.
