3D has had more than a few negative descriptions attached to it during IBC, with the word headache usually figuring somewhere, But Kevin Murray, systems analyst at NDS, admits that ‘nightmare’ might be more apt. He told a packed audience at IBC’s ‘What can stereoscopic 3D offer? ’ session that television was going to force graphic designers and associated disciplines to think very carefully about how they handled 3D graphics.
“While everyone accepts that 3D is going to have serious problems”. He explained that over-sudden movements towards the viewer might well result in the viewer might well result in the viewer flinching, and spilling their cup of coffee. ”Nevertheless, the vast majority of our test viewers like it and say they want it.
“But the technical challenges, especially for graphics, are huge.
Imagine placed?
What about subtitles?
In the US you have to cater for on-screen emergency alerts.
Were do you put the on-screen bug?
How should you handle EGP-type overlays, or-coming next-updates?
What about the interactive layers?
How will you handle the huge amount of on-screen data in a 3D sport game?
These have all to be thought about, and planned for, and a consistency achieved”.
Murray told delegates that, as if this wasn’t enough, there were then the problems of video manipulation.
Shrinking a video image to a picture-in picture was fraught whit potential danger unless handled sensibly.
For those broadcasters supporting PVRs they’ll have to consider how to cope within 3D, such as the fast forward button “ Depending on your ‘tick mode’ algorithm the end result could be interesting!”
He said broadcasters needed to think long and about where to think long and hard about where to place subtitles and similar captions.
“in 2D they are overlaid. In 3D it is extremely easy to introduce troubling conflicts that will not help eyestraim”
