How can the TV detectors tell if your TV is colour or black and white?

Question

The sneaky gits..

Answer 1

In all honesty they can't, they know who has and hasn't got a license and look for aerials. The signal is the same into the house whether you have a colour of black and white TV, the only difference is within the TV itself.

Answer 2

about £80. the licensing pickpockets can unquestionably inform you which ones ones form of (crt-now no longer flatscreen) set you're observing because of the actuality the fairly severe voltage in a CRT (cathode ray tube) elements off an better useful connect up the medium wave band than a b/w set does and the licensing authorities have fairly smooth kit that are in a position to %. up those indicators and may tell the version. flatscreen contraptions (both plasma and liquid crystal exhibit) use nowhere close to to the mandatory voltage a well known set does to furnish a photograph so the BBC will may prefer to start up guessing decrease decrease back. and as there are literally not any b/w flatscreens for sale they are going to all be lined with a colour licence.

Answer 3

Following these eight cycles, a phase shift in the chrominance signal indicates the color to display. The amplitude of the signal determines the saturation. The following table shows you the relationship between color and phase:


Color Phase
Burst 0 degrees
Yellow 15 degrees
Red 75 degrees
Magenta 135 degrees
Blue 195 degrees
Cyan 255 degrees
Green 315 degrees

A black-and-white TV filters out and ignores the chrominance signal. A color TV picks it out of the signal and decodes it, along with the normal intensity signal, to determine how to modulate the three color beams.

Answer 4

Since the TV licence is for "A device capable of receiving a broadcast transmission", it makes no difference whether it's a black and white or colour television, on a PC, video or DVD recorder, from cable, satellite or aerial. There is only one licence and one fee, nowadays...

Answer 5

The tv detector vans use the same technology that found the weapons of mass destruction in Iraq.

Who paid for the development of this exclusive, ahead of its time, technology? The British Public? Nah, it's just rubbish and they use lists of people without licenses, and harrass them ad nauseum. It's the same principle of everyone without a gun license being harrassed and considered guilty of illlegally having guns: it just would not be tolerated.

Good luck! Rob
