In most of your reply you have failed to account for the third world (and frankly a decent chunk of first world). It seems to me you don't have an understanding of your user base. Please dig into how many people are actually on HD-capable bandwidths. I am glad that Silicon Valley is driving it since they have users all over the world, not just fiber-enabled users. If and when other people have a better aim, vision and understanding of the problem, I think you should find a good collaborative atmosphere. In the meantime, let's not design for 100m users when we should be thinking about 2-3b users.

You aren't disagreeing with parent, who said that the 2-3B users don't have HD-capable connections. The parent is saying that the industry should try delivering SD-quality video before hand-waving about near-infinitely compressible HD-video. For example, one solution for low-bandwidth environments is to edge-cache it (farther toward the real edge than "local ISP") and then spread it locally via peer-to-peer short-distance radio (wifi, bluetooth, local cellular). This is not a 100x data compression challenge; it's a local delivery infrastructure challenge.

>Please dig into how many people are actually on HD-capable bandwidths. I did mention Youtube are doing 1080P at 2.2Mbps. We could be doing 1.2Mbps with HEVC today already. That is HD-capacble bandwidths. And 720P is also HD. >In the meantime, let's not design for 100m users when we should be thinking about 2-3b users. There are roughly 5 Billion Phones users world wide, 3.3Billion of users with Smartphone. 1.3 Billion user on LTE, with most of the other 2.3 Billion user do have LTE capable Smartphone but not on LTE plan or their country are on its way to LTE. There are still 600M user in China that does not have Smartphone but could have had LTE should they choose to. India is skipping 3G and moving on to 4G. With 300M Smartphone user and adding even more as we speak. We are expecting to have 2B+ users on 4G or 5G by 2020. With the majority other 1.4B user chooses not to be on LTE rather then inaccessible. And in developing part of the time world, there are little incentive to keep the 3G equipment and spectrum. I pointed out the we have lots of Network improvement in the pipeline. Purely in terms of technical achievement, arguably speaking Massive MIMO is the biggest invention since wireless communication itself. We will see huge increase in capacity, available for everyone and cheaply. It isn't about first world or third world. US used to have the worst Telecom services, even compared to some third world countries. But Smartphone has changed that because users are willing to pay to get better services. They moves up the ladder, the impact were much more profound in those developing countries. As pointed out by Benedict Evans, there are lot of places where charging the phones cost more that the Data Plan. I am not saying we shouldn't care about the rest. But a new video codec focussing on 100kbps is wasting energy actually for the few rather then many. By the time this video codec that is done with research and implementation, and hardware available to mobile user, we are talking about a cycle at best 3-4 years, or more likely 6 years+. Network bandwidth would have improved more so. Another point worth mentioning, the post about Netflix 270Kbps encoding. x264 and x265, were never great at encoding low bitrate. rmvb / Rv10, or Rv9 EHQ from Real Media ( God I am old.... ) has always had better perceived quality at those bitrate. It isn't that we need a new codec aiming at low bitrate, it is that the current encoder are hardly optimise for those bitrate. There is a lot could be done in decoder filter, pre video cleaning to achieve better perceived quality at those bitrate. And RMVB used to do a very good job at it. The new RV11, which is based on HEVC, may have applied those tools as well. ( Not tested RV11 so I am not sure )
