QMS VRR Support Coming to Apple TV 4K to Prevent Blackouts When Changing Content Frame Rate
QMS VRR prevents momentary blackouts that occur when switching between content playing in different frame rates. As TechCrunch highlights, users who already have the “Match Content” setting for frame rates turned on may already be familiar with this, “since it happens almost any time you start streaming an actual show or movie from most apps.” From The Verge‘s Apple TV 4K review:
The third-gen Apple TV 4K has another bit of future proofing up its sleeve: later this year, a software update will add support for what’s known as QMS VRR. This enables compatible TVs to switch between different frame rates without any black screens or noticeable picture interruptions. How many TVs work with QMS VRR, you ask? Well, zero at the moment. But you’ll start seeing them hit the market next year; stay tuned for more news about this feature at CES. I’ve never been that bothered by the short flicker when changing frame rates, but I won’t miss it, either.
It is worth noting that QMS VRR does not prevent blackouts when switching between color spaces or HDR content. The new video quality feature is set to be added via a software update to tvOS. It is not clear if the feature will also come to the second-generation Apple TV 4K, but it could make sense since that device introduced support for high-framerate HDR content up to 60 fps and HDMI 2.1 last year.

Govt testing plans to cope with blackouts that could last up to seven days – report
Plan for three-hour blackouts revealed in gov documents – here’s exact time your home would be affected
A PLAN for three-hour blackouts has been revealed in government documents – and they show the time your home would be affected.
The Electricity Supply Emergency Code (ESEC) gives the PM sweeping powers to introduce rolling blackouts across the UK to conserve electricity.
Blackouts could cause misery for millions across the UK if they take place this winter[/caption]
Blackouts would be introduced in case of an emergency scenario where there is a massive shortage of gas.
Government documents, which were created before the current energy crisis, show how this would play out.
It comes as the National Grid warned that power cuts could become a regular occurrence during cold January and February nights if electricity generators run out of gas.
The gov plans are split into several stages with the first being direct appeals to the public to reduce their power consumption.
The second is slapping restrictions on companies’ electricity usage by requiring them to drop their consumption by a certain per cent.
The final stage, dubbed “rota disconnections”, would be rolling blackouts for homes across the UK.

The documents also break down where and when the blackouts could take place in an emergency scenario using “load blocks”.
Power in Britain is provided by a handful of suppliers who divide their distribution into 18 of these blocks, which work like postcodes.
Each “block” is assigned a letter between A and U, except for the letters F, I and O, which are not used.
You’ll be able to find yours in an electricity bill. If not, get in touch with your electricity provider to find out.
For example, looking at Level 1 on the document (above), if you live in block A, you would have a power cut on Monday 12:30am to 3:30am, Wednesday 3:30pm to 6:30pm and on Sunday 12:30am to 3:30am.

These blackouts will be based on where you live and how power is supplied to your home, which means your neighbours might not experience a blackout while you do.
Households belonging to each “load block” are scattered across the country, so one area isn’t in complete blackout at the same time.
Blackouts could occur every day of the week in eight three-hour slots, with the first starting at 00:30 to 3:30am and ending with 9:30pm to 12.30am, according to the document.
Power cuts will be based on a 18 levels of severity which differ depending on the availability of gas supplies.
The first would see rolling blackouts three to four times a week, either at the start or the end of the week.
Level two would see power cuts occur six times a week and level three will disrupt electricity flows to households for 27 hours a week.
Level nine is the point at which homes face spending more time without power than with while the most feared scenario is a “total shutdown” of power supply indefinitely.
Certain “protected sites” like hospitals, food manufacturers, oil refineries, some ports, financial services, essential water and sewerage installations, major airports and digital and telecommunication services will dodge the worst of it – but not for long.
They may be forced to reduce consumption in the worst of circumstances, while priority is given to the “maintenance of life” and to “minimising the risk of disasters”.
Meanwhile, the BBC has prepared secret scripts for use during blackouts this winter.
The scripts set out how the broadcaster would attempt to reassure the public should there be a “major loss of power”.
Brits would be advised to use car radios or battery-powered receivers to listen to emergency broadcasts on FM and long-wave frequencies usually reserved for Radio 2 and Radio 4, according to a Guardian report.
One draft script, seen by the paper, warns a blackout could last for as long as two days, with hospitals and police put under “extreme pressure”.
Russia has threatened to turn off gas supplies to Europe this winter in retaliation over its support for Ukraine.
Moscow has already been accused of sabotaging the Nord Stream pipelines with “pig” drones packed with explosives, which suffered catastrophic damage earlier this month.
Though the UK does not rely on imported gas from Russia, it will be hit by a supply shortage in Europe, which is where it sources most of its gas and electricity.
A Government spokesperson said: “The UK has a secure and diverse energy system.

“To strengthen this position further, we have put plans in place to secure supply and National Grid, working alongside energy suppliers and Ofgem, will launch a voluntary service to reward users who reduce demand at peak times.’
“But Britons are already preparing for the worst case scenario by stocking-up on portable generators and torches in addition to winter clothing, thermal underwear and candles, according to industry reports.”
