AMD "Navi 48" To Feature AV1 Hardware Encoders with B-Frame Support

[Dr. Dro]

Pure speculation, the only it becomes that is if broadcasters actually push for it otherwise I expect AV1 or AV2 to become the next "universal" format after H.264 & IIRC there's already(?) competing standards in China!

Not really, VVC is already slated for use in the next generation Brazilian television system by the SBTVD Forum, it will use a modified American ATSC 3.0 system as a base. A fully functional transmission with the draft standard was demoed back in June by Globo, the largest broadcaster in the country.

I believe the European DVB system is also receiving a new revision to support the codec, as the name implies it is "versatile" and works particularly well for over the air digital TV broadcasting as it is capable of retaining decent image quality at low bit rates and the adaptive resolution capability is of particular interest for this use. It will work great for internet streaming as well, the problem remains licensing.

And that's why I speculate AV1 or AV2 could be the better standards going forward, especially if China backs them. Same goes for VVC, unless China backs it there's unlikely going to be a universal next gen standard.

I don't disagree, AV1's relative freedom is much better, but gotta remember TV stations and the movie industry rarely think like customers, they love closed, proprietary formats. It's also in the patent holders' interest to get these on board, so to sweeten the deal they will grant them licensing on better terms too. In the end since people like to watch, edit, play around with movies and stuff, some degree of support for these proprietary codecs is necessary.

Wonder if those AV1 patent trolls are still around though

But frame generation also uses data from previous states.

Unlike generation / interpolation, compression is based on input frames. The input frames are the goal/target and are used as reference to guide the various compression stages.
After motion compensation from nearby frames (past or future), the difference of the being-compressed frame versus the input frame is calculated.
This "residual" further refines the compressed frame, and is stored in a lossy form. It brings the frame closer to the input one.

I'm Brazilian too. The choice of H.266 as the codec for the new Brazilian digital TV standard is, at the very least, suspicious (unfortunately), since they could have chosen the free codec AV1 or waited for AV2.
(the world may know that here there is corruption among politicians everywhere and that free things, with AV1, hinder corruption)

Yes.

But here in Brazil, the only equipment that will need to convert the signal image to h.266 is the equipment that will send the signal to the transmission towers. All other equipment and cameras can continue to use other codecs. Filming, video editing and even video storage will be able to be done with other codecs.

I really hope that all hardware manufacturers do not support H.266 and only support codecs from the AOMedia group (AV1, AV2, etc.).

I mean let's be real this isn't gonna happen for a long time (and possibly, an "if ever" applies here), but the standard was drafted and is a real thing

Does anybody know if current video editors are ready to take advantage of this? DaVinci Resolve? Final cut etc?

AMD, incomprehensibly, has always had a terrible relationship with software development companies. It is impressive that the company's managers never put themselves in the position of consumers.

If hardware companies support H.266 (in their cameras, video cards, etc.), all the work and money spent by the companies that are part of the AOMedia group will be for nothing.
