Versatile Video Coding (VVC) / H.266: HEVC successor

[ksec]

I think it would be fair to say if HEVC decoder had similar optimisation of dav1d it would be faster / lower resources. The thing is dav1d has crazy amount of Assembly code in it and still getting even more assembly optimisation as of now. There are some cases dav1d is even faster than AVC decode.

Anyway back to VVC. I cant wait to see Brazil’s ambitious TV 3.0 using VVC + LCEVC together. I gather the rest of the Broadcasting world ( Europe and Japan ) are waiting for their results as well before moving forward. As I believe this is the first time a system has been designed with both OTA and OTT together. ( Not OTA plus OTT, but both having same weight. ) Latest VVC+LCEVC shows additional 40% Bitrate reduction on top of VVC on 4K materials. Large field test in 2025 and Full commercial deployment in 2026.

So, what bitrates are we talking about for VVC+LCEVC? Assuming 25Mbps for HEVC 4K HDR10.

Yeah, so I restricted it to actual implementations specifically, because we all know how the theoretical performance compares.

Yeah, software HEVC was never that big a thing as HEVC adoption was driven by hardware DRM & decoding scenarios. AV1 has had a much slower adoption ramp and is intrinsically a lot more complex, and so it's gotten a lot of sustained optimization over years.

It is exciting indeed!

I do wonder how Brazil is dealing with the IP licensing of VVC.

I understand from a Brazilian friend that in order for patents, etc., to be recognised/acknowledged in Brazil, they have to be filed in Brazilian Portuguese. If they are not, they are ignored!

That's not unique to Brazil, Chinese patents have to be filed in Chinese, Japanese patents in Japanese etc. Some patent offices allow patents to be first filed in English (and the translation to follow some months later), but not exclusively in English.

As an aside, patents are only valid in the country that issues them, outside that country, they aren't worth the paper they are printed on. So, if you want your invention to be patented in a certain number of countries, you have to file on the patent office of every one of those countries separately. There are of course the EP patents, which apply to more than one country, but that's just only for some countries. And even then, some EPO countries (such as Greece) require a full translation within three months of the grant date to the country's official language for an EP patent to be considered valid in the country.

Lawyer firms have people that do the translation and also know how to file on the patent offices of all "important" countries and the EPO. It's also why MPEG LA's patent lists are so long btw, because one invention may be listed as several patents (of different countries).

Now, how will Brazil deal with the licensing requirements? They will pay a royalty to each licensing entity, duh.

I think we both know the answer to that one!

Huh? I don't understand your post. But anyway, my point is, there is no magic way around SEP royalties just because you are not in the US. Companies that contribute inventions to standards organizations are smart enough to file in every "important" country.

Even software such as VLC exists because French law has a specific carve-out for computer software, other stuff still pays royalties.
