Disney Research has found a way to preserve the awesome quality of high-dynamic range or HDR videos when they’re shown on consumer-level TVs and displays. See, HDR videos can show shadows and light better than footage taken by conventional equipment can — in fact, the setting’s purpose is to record what we see rather than what the camera sees. Problem is, typical consumer TVs and screens these days aren’t capable of displaying them, unless they go through a process called tone mapping . Unfortunately, existing tonal mapping techniques downgrade HDR videos’ quality, so that most of their details get “lost in translation, ” so to speak, or introduce unwanted effects like flickering and ghosting or after-image. Disney’s new tonal mapping technique, however, prevents these things from happening. If you’d like to know the science behind the technique, make sure to pore over the team’s research paper for more info. Or, you know, you can just watch the video below for a demonstration of what the technology can do. Comments Source: Disney Research

It’s no secret that AT&T throttles its users unlimited data connections. The company has been rather open about the policy. However, the carrier insisted that the practice is used to reign in the biggest bandwidth consumers, only necessary to keep network congestion at a minimum. Well, that doesn’t seem to be the case. Big Blue’s info page for “customers with legacy unlimited data plans” explains that when folks hit the 5GB threshold, they’re gonna experience reduced speeds until the billing cycle is up. The reduction to compensate for congestion bit only applies to phones with unlimited data between the 3GB and 5GB mark. Of course, the FCC claims AT&T hasn’t been clear about such practices, including just how slow the connection can get, despite the carrier claiming throttled customers get a text message when speeds are cut. In fact, an Ars Technica report found those figures to dip to half a megabit per second. At any rate, if you’re a big data user, you can expect slower speeds above 5GB, even when the network’s traffic is manageable.
