Sony's Bravia Core streaming service will deliver video comparable to Blu-ray

I don't realistically see this as being a killer feature for most users, but it's super interesting none the less.

Sony are saying the bitrate will be "Up to 80Mbps", which is around 3x that of most UHD streaming service profiles. However there will be significant diminishing returns on the perceptual quality at this bitrate - 20Mbps to 40Mbps for example will only increase perceptual quality by a couple of percentage points. Much of this "Up to 80Mbps" will be wasted perceptually speaking.

It's also worth keeping in mind that the encoding on BluRays is often lazy because there's lot of space available, where as a huge amount of work goes into encoding content for streaming delivery in the lowest bandwidth possible for a given target quality, using technologies like per-title and per-scene encoding.
