Design Cost is the main factor in cost increase, but that bare little relevance to unit cost without specific volume accounted for. 5nm and 3nm are relevant not only because of cost but Die Space and Power Usage. Where in Mobile devices you are expecting a budget of sub 100mW for Decoding. In Laptop you have the luxury of budget increase by 10x / 1W if not more on a GPU.

MPEG-LA has released a press release about their VVC patent pool: https://www.mpegla.com/wp-content/up...2021-01-27.pdf

But thats intresting, but to me it sounds a bit odd... ”We cannot make an sub 100mW decoder on current silicon so lets use software decoding instead!” I though that the key factor was that they didnt wanna waste money on silicon for an feature that might not see wide adoption, and that av1 needed quite a bit of silicon budget.

I've heard estimates that an AV1 decoder can take twice the silicon budget of a VVC decoder. That extra cost of AV1 HW support is likely higher than any savings from not having a per-decoder licensing fee.

VVC is dead on arrival as many have predicted. |

The article doesn't say that VVC is dead only that “potential licensees won't know total VVC royalty costs until both pools release their royalty terms” |

And again, ValosMedia, or specifically Qualcomm. Given all other members of Valos are already in either MPEG LA or Access, Qualcomm are not in any the pools ( yet ). [1] https://accessadvance.com/hevc-advan...-hevc-license/

I wonder how much of the spec they implement, since nothing has trickled down for consumers to test yet. AV1 bucks the general trend of having a very stripped-down baseline MPEG profile that hardware can implement; its baseline includes most of the more complex tools and colorspaces that hardware pretends don't exist and therefore the state of the art never really budges as much as you'd expect.

MPEG has been great at making very thoughtful choices to optimize for HW decoder complexity, but AV1 didn't get nearly the breadth of input about HW implementations, and efforts were very much focus on SW decoders for a long time. |

There are relatively few users of lossless and they don't care much e.g. about speed, so I'd be glad if they just implemented it based on the algos already in place and continue to optimize the code base for lossy encoding.

A nice feature of HEVC and VVC is the ability to use lossless coding units selectively in a lossy stream. Lossless can compress stuff like a black/white checkerboard more efficiently than any frequency transform. |
