This is such nonsense. In my opinion the BBC should be paid for by a proper tax, as an informed public benefits everyone, or they should just give up on calling it a license. The people going around houses just send threatening letters, and act as though they have some right to enter your home and inspect it (they don't). They go around terrorising people who don't know their rights, but don't watch TV anyway. I rout…

Then there’s the issue of the cost to enforce licensing.

The warrant revealed that a BBC contractor had used an "optical detector" to reveal the possible presence of a TV.[10] The warrant stated that: "the optical detector in the detector van uses a large lens to collect that light and focus it on to an especially sensitive device, which converts fluctuating light signals into electrical signals, which can be electronically analysed. If a receiver is being used to watch br…

No, it sounds like a telescope focusing onto a single pixel (i.e. just the back of the curtains), and then using the output from this pixel with a lock-in amplifier tied to the broadcast signal. The sensitivity would be enormous due to the lock-in.

With a CRT you would be able to do this with In today's LCD world, I guess something similar could be done for a whole pixel-average of a whole frame, and then look at the time-series of that to correct for lag in digital television / internet etc..

While reading I thought, "for sure we will get to the part of the article where the British realized their folly and discontinued the licensing." But that part never came. Brits: is this for real, does this still exist? Do you pay a license to use your TV? Is it only for OTA programming or using the device in general?

It's only for OTA programming or to watch BBC online streaming services. You don't need one for eg watching Netflix or playing games.

In Switzerland, you have to pay the tax if you could possibly watch TV at home, so just having a TV or even no TV and an internet connection makes the tax mandatory, even if you don’t French/German/or Italian.

The inspector got me at my apartment once and was certain that I needed to pay the tax. I invited him into my apartment and he saw I had no TV, radio, or Internet, and left very disappointed.

Swedish public service transitioned from a per-household fee (for households that held devices capable of showing RF broadcast TV) to a per citizen tax January 1st this year. Of course, they go to great lengths to avoid calling it a tax, but... well, it is a tax.

I don't really like it. There's no opt-out any longer. And the content is predictably all-consuming leftist.

Sounds like they are analysing the dynamics of whole-frame integrated brightness change. You don't really need any spacial resolution for that, just enough for separating houses/flats. A single-pixel camera with sufficient aiming, anything beyond that just requires mow processing. I don't know the specific legislation but I'd expect them to be safe.

How do these work? Is a TV somehow different than a large monitor?

> The most common suggested method was the detection of a signal from the TV's local oscillator.

See: superheterodyne receiver. Most modern radio receivers generate high-frequency signal for tuning, which leaks as radio signal (receiver becomes in some way a transmitter). However, it's not confirmed if these vans had working detectors, or were just for intimidation.

There were also stories about:

- Radar detector detectors (in places where radar detection devices in cars were illegal)

- Broadcast radio receivers detectors installed near roads to measure popularity of radio stations among drivers

Yes, it still exists. A TV Licence is required to watch any television programme live as it is broadcast. This applies to online live streams of TV channels, even if viewed on a PC or mobile phone. It is legal to use a TV set without a licence, so long as you do not watch any TV programmes live. So it's fine to connect it to a laptop and use it as a monitor, or listen to radio programmes through it, for example.

> so long as you do not watch any TV programmes live.

Law was changed in the last few years to make this applicable to on-demand content too from BBC iPlayer

Watching television without a licence in the UK is actually a criminal (rather than civil) offence, and hundreds of thousands of purple are convicted each year of the offence. https://www.theguardian.com/society/2014/sep/24/in-court-non...

To be clear, this only applies to television that is paid for by the license (BBC etc, including streaming via iPlayer). I have a television and use it only to watch Netflix and Amazon Prime Video, and am thus not required to pay the license. Which goes to show how ridiculous these vans are, since they can't tell where you're getting the content you're watching.

Sounded like they do have technology to tell what content you are watching, which is even more ridiculous.

It does, and it's every bit as ridiculous as it sounds, but I suspect it'll be discontinued within the next decade or so and the BBC will become something sane like a normal subscription channel.

Anecdotally I've noticed a sea change in general-topic UK discussion fora over the past five years or so. It used to be the case that anyone criticizing the BBC was downvoted to oblivion, but the old reverence for it as an institution is very much a minority view now.

EDIT: it's not just us, by the way; the US is actually in a small minority of countries who've never had a TV tax.

You need a licence if you watch live TV as it's broadcast, or if you watch BBC iPlayer catchup content. You need a licence for any device that you watch live tv as it's broadcast. You need a licence to watch live tv, no matter where it's broadcast from. The wording of the law says "installed or used to receive", so in theory you need a licence if you have eg a tv plugged into an aerial. They don't prosecute those cas…

Record and time-shift it so that it is no longer "live TV?"
