The IQ of image quality Wendy Aylsworth
SVP Technology, Warner Bros, Technical Operations and SMPTE President Region: Global
Interview by Carolyn Giardina I
mages have numerous characteristics from resolution to dynamic range – but what will attract the attention of consumers? That is a question that
Wendy Aylsworth, SMPTE president and one of Warner Bros’ senior technology chiefs, is exploring.
“It is important that we don’t look at any single quality
parameter,” she says, talking about displays for consumer electronics. “A lot of buzz surrounds Ultra HD, but not only are new displays capable of more resolution, they are capable of having different colour gamuts, more contrast ratio and dynamic range and they are able to handle faster frame rates. “If I were to rate the quality parameters of a display, then the dynamic range and colour would go hand in hand and are the most obvious changes we can bring to the consumer today. I think the second most obvious change that the consumer can perceive are frame rate differences. “To see the difference
between HD and Ultra HD you have to be standing quite close to the screen. With dynamic range and broader colours, you can actually see those across the room.” Aylsworth’s conclusion: why
address just one characteristic? “I think the content community is looking to move towards the ones that are beneficial at the same time, as opposed to picking just one.”
She is also examining how to deliver content to consumers on more devices, including how to get high quality content locally stored and how to make it in a more cost-effective manner. These are issues that SMPTE is looking at, including how to compress a larger
colour space to a Rec 709 colour space so that all TVs can read that information and display the correct information. Turning to high frame
rates (Warners released The Hobbit: An Unexpected Journey in 48fps) production, Aylsworth says, “we are past the technical hurdles and now it’s about getting [high frame rates] into the hands of the creatives. It’s about the creatives experimenting.”
She adds that on the
exhibition side of the equation, “the ability to get past 60fps is the next barrier and people are looking at how to do that with the next generation of projectors.”
