Turning standard definition into HD with ҹɫÊÓƵ&) 100vw, 1024px" />

The human eye does not see a fixed resolution. Rather, human vision is based on angular resolution — that is, how far apart two objects need to be to be able to distinguish between them at a set distance. Angular resolution is a function of humans’ visual acuity, and it is that visual acuity that we take advantage of when upscaling content.

In an aircraft cabin, a few things determine visual acuity and the ability to perceive resolution differences:
• The size of the monitor
• The resolution of the monitor and the distances between individual pixels in the display
• Passenger’s actual vision acuity, e.g. 20/20 vision
• Passenger’s distance from seatback screen

What this all adds up to is that even with 20/20 vision it is virtually impossible for a passenger sitting in Economy class to detect differences in upscaled vs. native resolution on a 13-inch monitor. Even when moving to Business or First Class, where an IFE monitor might be bigger or further away, the perceived differences in native and 4K content are minute. This is because the bigger the screen, the further away a person can sit and still enjoy the higher resolution.

With this knowledge in hand, airlines can decide what level of passenger experience they want to deliver based on their unique brand promises: by choosing efficiency in media spend by upscaling standard definition content, or by choosing native 4K content and taking full advantage of Astrova’s 4K OLED displays and their outstanding color accuracy and perfect black contrast.

What’s the market standard?

Right now, most people view content—games, videos, films, phone graphics—in 720p or 1080p, even if their device is 4K-capable. This is largely due to the bandwidth demands of 4K content when viewing on phones, tablets, and connected televisions.

Because 4K content is very taxing on a network, many providers throttle service when watching on their devices. It’s very common that people don’t actually view things in the full resolution they think they are.

Upscaling in the cabin environment

The combination of a 4K picture with perfect black contrast and the cinema-quality color of OLED displays delivers a premium viewing experience—regardless of whether that content was native 4K or upscaled 4K. This entices passengers to make use of your IFEC offerings delivering deeper, more robust passenger experiences.

It also gives airlines like yours an opportunity to maximize your IFE investment dollars while remaining ahead of the curve when it comes to the world of 4K content. You get the best of both worlds: 4K content and an efficient media spend.
