查尔斯·克劳斯: If you think about 4K, I was at NAB and everything's 4K cameras, 4 k无处不在, there's a small problem with that ... and it's worse outside the US. Look at the bandwidth you need to do just straight up 4K, all right, 20 to 25 Mbps. With high dynamic range, it’s a little bit higher.
I saw 4K virtual reality, with multiple views. How many views do you want to present? Multiply that by that number. If 80% of US households have less than 8 Mbps, guess what? This is one reason 4K took off like crazy for a little bit but now it's kind of stalled out, not a lot of content.
I know there are services like at CuriosityStream where you can get standard definition, 高清晰度, 和4 k, 你要为每一个买单. 但, there's just not a lot of demand yet for 4K for the simple reason that, hardly anybody has the bandwidth to get it even though everybody buys 4K TVs. 这是为什么?? Because that's all we sell. The manufacturers have found out that it's so cheap to make the displays, that's all they're making.
I was on a panel at NAB with the guy from Sony that was talking about the “huge demand from customers for 4K.” I said, "No, there isn't. Try to buy something else if you go to Best Buy. That's all you can get. 这不是需求. That's industry push, but the content’s lagging."
I know the Masters are going to take one golf hole and they're going to broadcast it in 4K. That keeps happening but it's going to take time for the infrastructure to catch up. We expand our internet infrastructure every year, Akamai确实, 每个人都做, but it's not going to suddenly solve this problem in just a year. It's going to be a slow thing.
你知道, 另一方面, 4K TVs have software in there that kind of makes the picture look really good. Some people think they're watching 4K and they're not, just because the software does a pretty good job of cleaning things up.
