I wasn't aware that European countries weren't licensing codecs. Certainly I've had to buy both MPEG2 and VC-1 codecs for my Raspberry Pis in the UK. That could be because they enforce their codec licenses world wide to be safe.
In the US however, software patents are very much a reality, and therefore HEVC has a licensing cost.
Yep - though my understanding was that HEVC's costs were reduced after some initial hesitation?
Regarding VP9, I honestly have no idea how you got that out of my post - I specifically mentioned AV1 and newer because they're not finalized yet and is targeting better-than-HEVC performance.
No - neither have I. Was up early this morning - fingers not typing what brain was thinking.
And of course, AV1 is a standard being designed by a multitude internet-computer electronics giants rather than the traditional AV-broadcast media giants, so making AV1/2/etc part of an ATSC standard would allow OTA-on-mobile to have one foot in the door.
Yes - though HEVC codecs are appearing (at least as possibilities) in mobile devices already aren't they? They're certainly there in lots of ARM SoCs now. (At least the decode side is)
Regarding the US forging it's own path, you're right in that the US is already doing this - much of the rest of the world uses DVB, but the US obviously uses ATSC. But just because we're currently using ATSC 1.0 does not mean we need to transition specifically to ATSC 3.0 - a good example of this is Japan and western South America which used NTSC but, because they transitioned later, instead switched to the newer ISDB which uses AAC audio rather than the older AC-3 among other things.
And ISDB is COFDM-based, like DVB-T/T2 (and ATSC 3.0). ISDB-T in Japan jumped a little too early in the video codec stakes though - they went MPEG2, whereas the South American roll out of ISDB-T has been H264.
Taiwan was an NTSC country that switched to DVB-T I believe. South Korea was the main other territory outside the US that went ATSC 1.0 (and looks to go ATSC 3.0 first) - though they did look closely at DVB-T2 (and their initial UHD trials used DVB-T2 ISTR)
The US (and Canada and Mexico) is a big enough market to dictate its own standard - but it does sometimes mean that the economies of scale, and the benefits of differing market forces generating different market demands are less beneficial. (Compare the number of ATSC USB/PCI/PCI-E tuners with the number of DVB-T/T2 models - or the number of DVB PVRs etc. to the ATSC market?)
It is a pity we haven't managed to end up with a world standards family (with scope for local customisation) - if anything we now have more digital TV standards than analogue colour standards (though the number of RF and Colour standard combinations - plus audio variations - in analogue was pretty mind boggling)
