Re: I wonder...
On one of the many anti TV-licence sites there was a story that claimed they were "using/trialing" a technology that matched the changing optical patterns in a room due to a display to that of broadcast TV programmes being transmitted/streamed at the same time.
Could be partly feasible in the sense of overall pattern timing (especially the extra brightness of certain adverts (assume you have those annoying brightness/volume boosts over there as well).
But I wonder if a cheap set or two of Christmas lights strung up in the window could defeat this? Or having a Lava Lamp on the inside of the curtain?
Course, you could use the system NZ used some years back - abolish the license completely (well it was that or give some of the money to the competing stations...)
