Evidence has been observed in code for Apple’s subsequent large spherical of software program updates – which include for iOS on phones, iPadOS on tablets, macOS on Macs and, of course, tvOS on Apple TV 4K – that Apple will assist the subsequent-gen AV1 video layout on its gadgets withinside the future.
AV1 has one essential advantage: it is extra green than cutting-edge video codecs (a ‘codec’ is the set of rules with the aid of using which a video is encoded for streaming, after which decoded for viewing). This way you operate much less statistics to move video on the identical high-satisfactory, or you may use the identical quantity of statistics to move even better–high-satisfactory video, consisting of helping 8K with out the use of hundreds of statistics.
AV1 is utilized by YouTube for all of its 8K motion pictures, and Netflix has expressed a want to exchange to AV1 for all streaming withinside the future, to lessen bandwidth use. At the moment, it is now no longer supported on Apple gadgets at all.

But as noticed with the aid of using Codeworkshop.net(opens in new tab) (thru FlatpanelsHD(opens in new tab)), the AVFoundation framework in Apple software program, which allows builders to inform the software program which codec a video will use, now consists of an AV1 alternative withinside the tvOS/iOS/iPad sixteen beta.

This is a totally robust trace that Apple will assist AV1 in its subsequent updates, aleven though we have got requested Apple for confirmation, and could replace if the agency responds.
Analysis: Will the Apple TV 4K assist 8K?
While having AV1 assist could be extraordinary on all gadgets for decreasing statistics use while looking motion pictures at the pass especially, or enhancing streaming high-satisfactory for the ones on a negative connection at home, the large query for us is whether or not the cutting-edge Apple TV 4K could be capable of assist its 8K capabilities, or whether or not the much-rumored new Apple TV (2022) could be had to assist 8K.
There are large questions over this. The first is the HDMI port at the cutting-edge Apple TV 4K. It’s already an HDMI 2.1 port, because of this that the relationship itself can cope with 8K at as much as 60fps. However, as referred to with the aid of using iMore(opens in new tab), the Apple TV 4K would not truely make complete use of HDMI 2.1’s better bandwidth, which could make 8K not possible because it stands. Think of it this way: the pipe is huge sufficient to address the go with the drift of 8K, however the pump isn’t always robust sufficient to fill the pipe.

Is the chip withinside the Apple TV 4K preserving it again? Something’s preventing that HDMI port from attaining its complete potential… (Image credit: TechRadar)
Could Apple improve the pump? The article above is from 2021, however as some distance as we are aware, Apple hasn’t finished it so some distance, so it can be that there is a few hardware obstacle apart from the HDMI port this is preventing it. Again, we have got requested Apple to verify if it’d be possible, and could replace if we pay attention again.
The 2nd query is the A12 chip that powers the Apple TV 4K. Apple’s chips have not protected hardware interpreting assist for AV1 withinside the past, because of this that there may be no ultra-fast, ultra-green interpreting of this video kind run on a devoted part of the chip. Instead, it’ll ought to finished ‘in software program‘, because of this that the use of the overall processing strength of the chip to decode the video.
The Apple A12 chip is sort of 4 years old, so the priority is whether or not it has sufficient strength to decode 8K video in real-time.
These worries may go with the principle rumor approximately the brand new Apple TV this is stated to release later this yr or early subsequent yr: that its largest alternate internally could be a more moderen A14 processor with extra RAM. This may deliver it the strength for AV1 interpreting, and it can additionally be the processor this is held again the cappotential to make complete use of the HDMI 2.1 port.
It is probably some time earlier than any of this involves fruition, however if you have one of the pleasant 8K TVs and were hoping for extra assist, Apple is as a minimum one step towards supporting you out.
