Most professional network cards have PTP support and a grandmaster is cheap enough or your colo provider will provide PTP as a service.

"The Web Audio API exposes access to the audio subsystem’s hardware clock." I can't speak for Windows and Mac but in ALSA this isn't possible.

Or just have a way for a chipset to expose it's clock instead of all the methods people use to guess using buffer fullness.

No consumer chipsets that I know of allowing drifting the clock to match an external clock source so PTP is a non starter. And I've not seen many pro sound cards with drifting support either.

Ooooh something I know quite a lot about: So for AES67 receive, in principle no as PTP stack exists for RPI yet. You could cheat like the majority of manufacturers do and just play the audio as it arrives instead of using the timestamps. Yo

The main driver tarball is GPL. All the tarballs are too complex to follow though, we extract them one by one here: https://github.com/OpenBroadcastSystems/mlnx-driver

This is definitely not correct. For many SIMDable workloads it's possible to achieve order of magnitude improvements over the compiler.

Have you done any work to see whether the NIC hardware packet pacing mechanisms could improve QoE by reducing bursts?

How do you think this will need to be re-architected for HTTP3? Will you do kernel bypass with a userspace stack?

RTP PCM packets timed to a Precision Time Protocol clock. As most (all?) PC audio devices don't support clock drifting the audio clock to the PTP clock, this application will either resample fractionally or click now and then. So not A

I like the way the author says PAL/NTSC video triggering is obsolete, when it's used every day for timing purposes in a broadcast facility.

I have 5G home broadband in London and receive 700Mbps down with no cap. There's service from multiple operators. Yes we've had teething issues but they were all resolved.

It's more than that even. They lobbied governments to mandate use of this technology such that whenever you buy any device (e.g TV, Phone etc) you have to pay a tax for something even if you don't use it

ISO is full of vested interests that don't want hobbyists, the interested public, academics, and professionals to access the documents and be able to implement them at a lower cost.

Nominally to cover the costs of production. However, this is a convenient barrier to entry for Open Source and amateur developers that many companies who are standards participants don't object to.

This is an argument for organisations to go back to being on-prem, running their non-public facing workloads privately.
