The fact it works so smoothly every day is kind of miraculous in some ways.
You can have a stream that works across the world on their decoder versus one in the US versus one here of different manufacturers, and they produce bit for bit exactly the same material.
that's quite remarkable, and do quite complex things and getting more and more complex and still be a bit exact.
There's a lot of work that goes into that.
They're different.
They're control systems challenges, whereas some are more mathematical.
I think there's a difference.
I think actually the interesting one is the audio.
That's true.
You can kind of notice when they move from full fat AAC to the... There are compressed versions of AAC that use spectral band replication.
You can kind of see it goes a bit tinny.
And that up and down is very jarring.
The video side...
is a lot smoother and there's less notice.
It's really the audio.
You can definitely feel it from when it's moved you from a different audio profile to one or the other.
I don't know.
We're surprisingly tolerant at skipping audio glitches.
I'm surprised people I know who are not video engineers, how tolerant they are, how tolerant they are to watching sports at 30 FPS, for example, whereas it should really be 60 FPS.
The world is a lot more tolerant to that, but audio people are very, it's an immediate feedback mechanism of all.
