周王: The most difficult thing here is a good quality QoE metric. So you have to have an objective QoE metric that can very accurately predict how humans perceive video quality. It also has to be very flexible, versatile, to be deployed into all these points.
It has to be computed in real time with hopefully low cost, 在竞争方面, so that I can receive all this 信息 in real time, and then I can look at the whole picture. So, of course, this is the most difficult problem. And if we look at the traditional method, 或者是最先进的, somehow you can see that the state-of-the-art objective video quality metrics.
So, 例如, 的PSNR值, SSIM, 复合型SSIM, Muvi, and the other methods that are out there, most of these methods are open-source. You can get them-- Can they satisfy us? 问题是, 我必须, unfortunately 我必须 say, "No," because they are lacking certain properties, very important properties.
I hate to say that, because, like SSIM, I was the original author of SSIM and I love it. I spent so much time to show how it works, 但现在我不得不说，在… picture I showed just now, 这还不够. You have to do a lot more on top of that in order to produce something that you can use in the video distribution monitoring solution.
