- shmerl 6y agoThat sounds good, but AOM also provides a rather heavy weight protection against patent trolling and similar threats which is a benefit. It's similar to OIN in that sense.
- viktorcode 6y agoReference implementation is irrelevant to the patents which cover the use of underlying codec. The codec might get AOM protection, but then there's always some companies with patents outside of AOM. H.265 debacle with 2 patent holder groups is a good example of that.
- shmerl 6y agoThose outside the AOM will face the combined power of AOM if they attack. In other cases it depends on who defends the codec. H.265 is an anti-example, because there patents were pooled for offensive purposes to begin with, while AOM pooled resources for defense. I.e. something like MPEG-LA exists to extort money, not to defend anyone. That's also why you got two separate pools there. Patent aggressors don't want to share, each of them wants to get all the loot for themselves.
