Are we being beamed into space?

The TV signals that have been beamed into space are analog signals (until very recently). If you can capture the signal and build a machine that can play it, you'll see the same thing my father did in 1960. If you capture a digital signal and want to play it, you have to decode it, which is much harder.

I don't know how digital TV signals are sent, but it's probably similar to internet signals, which are sent as packets. These have to be decoded and reassembled in order to make sense (if they ever did make sense, that is!).

So the little green men would find their humano-porn wrapped up in little packets, like veggies at Scout camp or sushi.

Don't forget the wasabi.


The analog signals would degrade over time and distance, but those data packets could come through almost intact. With digital tv, the signal either appears intact or not at all. In the end, those distant aliens will get snowy, barely visible first run episodes of Leave it to Beaver, but decades later, they get clear, but jumpy pay per view donkey gangbangs via satellite. :eek:

picturing all the old sl bugs projecting into space like the beginning of 'contact' in a big bad flashback;) the aliens will greet us with outstretched hands and their heads up their butts :p

I wonder if Jig's question is really just a polite way of asking a different question - are aliens from space already members of SL and living among us? What a good place to hide, you must admit! And it starts to make sense of a lot of strange things.... Didn't Linden Lab get formed shortly after one of those UFO sightings? What's going on, eh?

Do you think those neighbours of mine who live in that black box could be invaders from space? OMG! Hal might be on to something!

I know someone that makes a living breaking into sytems this way... not by stealing, by selling the information on how they went about it. sytem managers can close the holes, they get paid, everyone is happy. I certainly wouldn't call anyone doing that an idiot... more like shrewd use of talent.

and just to have fun and add to the thread, did you know the fbi posesses a fun little toy that they can aim at your monitor and will show them what you see? nifty little gadget works right through the walls... it was made for crt's, not sure if it'd work on plasma or lcd... but it's not new tech so who knows at this point


Thanks a lot VOID. I just pulled my old foil covered commando helmet out of the closest. :mad:

But yeah you got a point...I guess the ones I knew who were just doing it for fun (don't work with or hang out with any of those guys now) made me biased against all hackers, but what you're talking about is an actual important and valuable service, which is why the ex-leader of the PN was taken on as a consultant for a brief time by LL (or so I read/heard and heard again)

This is probably false.

There's lots of official bullshit going around about picking up TV signals through walls. For years the BBC have been pretending that they could pick up TV signals through walls in a way to encourage people to buy a TV licence. They used to send fake TV detector vans through the streets of the UK in order to scare people.

The only way they could really find out whether you had a TV was to see if your home had registered a TV licence and if not, they would then send a guy around to listen outside for the Dr Who theme music or something. haha

It is possible to pick up some sort of obscure signal from a TV. But when you have a street full of houses then it's almost impossible to know which house that signal is coming from.

Have you considered that someone could be reading what's on your monitor from a few rooms away? It's unlikely, but possible, as work by Cambridge University computer security researcher Markus Kuhn shows.

A radio antenna and radio receiver - equipment totalling less than £1000 - is all you need. Kuhn managed to grab the image to the left through two intermediate offices and three plasterboard walls.

The last link describes how it is possible to reproduce the image displayed on a monitor by viewing a wall of a room the monitor is in.

Actually, the TV detecting is, technically speaking, piss easy. Easier than remote reading of a computer monitor. All you need is an am radio, and a home made directional antenna.
Every tv set has a radio frequency oscillator inside, try it. By comparing the waveform of the oscillator to the broadcast signal the detector van can even tell which channel is tuned in.

Where is that quote from ? I don't see it. I'm using the Flock browser with Greasemonkey and Strife's BBcode script. I'm wondering if this is causing some text to disappear.

That's true and I actually read it before posting. But there's a huge difference between a signal and a viewable picture.

The problem for the BBC will be that it's difficult to work out which house the signal is coming from. In the UK houses tend to be crammed together and the older houses have rather thick walls.

I used to work for the TV licensing folks and we never scanned houses. We had "visitors" that would visit each house and ask the occupants if they had a TV. They'd very often peek into the window before knocking on the door. ;)
