#2Can somebody explain what it means to hold the IP or rights of any of these standards?
Re: A Future Without MPEG
#3I don't really understand what the point of EVC is. From my understanding it's really two standards, one royalty-free that's slightly worse than HEVC/H.265, and one patent-encumbered/licensed that's slightly better than H.265.
The post here says "EVC is promising because it provides a quality that is comparable with or better than AV1, although less than VVC. EVC may have a chance if a licence will be published. However, this has not happened yet." I can only assume, from those numbers above, that "comparable with or better than AV1" applies only to the encumbered/enhanced variant.
It's hard to see why anyone would bother to implement the "base" standard vs. the already widely-deployed AVC/H.264, nor the "enhanced" one which seems to be roughly comparable to AV1 but with licensing costs attached (and as the post points out, no certainty at all about what that licensing would actually entail). Apart from those companies that hold the relevant patents, of course.

Does that really mean MPEG is no more ? Or is it hyperbole about something that happened 2nd of june ?
This would be huge (and really sad).

I presume it means you can require royalties from anyone who wishes to implement them. If you build a DVD player, you pay someone a royalty for those IPs, if you build a BluRay player, it's the same.
Having the "standard" means having the lion's share of the market, which means more money.

It means you can force people who actually develops products to pay you money for using your totally novel and not at all vague idea that you wrote down on a piece of paper 15 years ago that is so unimaginably revolutionary that nobody else could ever come up with something remotely similar.

The widely deployed AVC is still AVC Main Profile, which is what Youtube and many other Streaming / Broadcasting uses due to devices compatibility. EVC Baseline is expected ( or claims ) to be 20% better than AVC High Profile. So you should expect ~30% better than current AVC all while being royalty free.
The beauty of EVC baseline is that it is quite power efficient. Considering AVC already require the least computation in modern codec, EVC baseline offer 30% reduction in bitrate while requiring NO increase in decoding complexity and is actually 40 to 50% less in encoding complexity.
Note: None of these has been tested outside of its members as it does not provide a reference encoder due to "new" patents arrangement with this codec. So we have no way to verify those claims.
Edit: Will add the link to document with those claimed figures later.

It means that you can basically levy tax on compatibility. Anyone, who wants to make device or application compatible with standard has to pay a fee to you.

I would guess a patent expired, or the cartel disbanded or something like that. It's only dead to those who cant profit from it any more.
