蒂姆Siglin: Can you just give a quick synopsis on sort of the differences between FairPlay and 都? I know Apple famously, years ago, had a hard block on content where you couldn't share it. And then Steve Jobs pushed to allow for FairPlay, which allowed you to share it to a certain level. 都, 很明显, seems to be a much more traditional sort of hard lock, but can you give just a quick synopsis of either the top two or the top three?
奥尔加Kornienko: 好吧, at this point, most technologies do roughly the same thing. There are some minor variations of what you can and cannot do--mostly based on device, whether or not you can do all protection levels. 但在一天结束的时候, most technologies are the same, with the exception being that if you are a DRM provider like us, Google and Microsoft give us the PlayReady certificates that we need to issue licenses and generate keys, whereas PlayReady and Apple dictate it in a different direction. They require content owners and content providers to actually get that same certificate. 但除此之外, from a perspective of the technology itself, 它们大致相同, 它们的工作原理是一样的, and they are geared towards their own specific device. So PlayReady works much better on a Windows device, 都 on a Chrome Google device or Android device, and then FairPlay for an Apple device.
Eric Schumacher-Rasmussen: Olga, let me just ask real quick. When you say it works better on those devices, what happens on the devices where it doesn't work as well?
奥尔加Kornienko: 好吧, I say "works better" from a perspective of--and this is the reason why we chose to go SDK-less--is that it takes out a level of complexity, the logic being that if Microsoft pushes out an update to the operating system, 到浏览器, 任何事情, they would test PlayReady as well. And the moment they push out a new update, first of all, it is 很明显 always backwards-compliant. 其次, to add any new features or any new modifications does not require our clients to do anything, doesn't require them to update on an SDK, doesn't require any sort of work. It requires work on our backend to implement all the features, 但是一旦他们实施了, it's also very seamless and it also takes away time that you would normally spend trying to add extra levels of development. 对我来说, I think it works better only because it takes away unexpected issues, 故障, 和复杂性.
蒂姆Siglin: 我还要加上埃里克, that SDK-less is a smart move because a lot of SDKs aren't very well-documented, and the SDK tends to come out after the operating system update. So there's this lag of a couple of weeks to a couple of months, sometimes even.
Eric Schumacher-Rasmussen: 好吧. 很好.
