I am missing an arrow that says "you are here".
And where's Hitler? I've heard he was rather popular in the radiowaves and all.

Or time travel but from the point of view of the people in that star system only, but surely not from the point of view of the traveller?
I could send a rocket towards your house at 1000km/h and in ~50ms send you a text in advance to apologize for it, before it arrives. Did not timetravel.
*beep* *beep* "dafuq?" boom!

Equally they may all be greeting each other everyday saying "heil hitler!".
They'll likely be oblivious to what a jew is, or that Hitler wasn't just "that guy that opened the human move-around-much-contest (olympics)".

What about "THIS IS SPARTA!".
Upon reception, the aliens come to us and upon arrival ask the first person they see "Hi. Is this sparta?".

Tosh.0 must have leaked from a DirecTV satellite.
There are actually quite a few satellites that have beams that go a bit over the edge of the earth. In my opinion these signals are the most likely to be received by alien civilizations because they don't have to travel through the atmosphere and were designed for (relatively) long-distance communication to begin with. Much easier than reception of some 11g router over long distances.
Also, when you would aim an antenna at "earth" and tune to, say, 546mhz you'd get dozens of different television stations. You would need some real precision to aim your antenna at just one of them. The antenna on a satellite is more directional, but you would only be able to receive once satellite for a short amount of time, as the world turns.

I'd say yes. For analog it should be relatively simple. For digital, they'll probably quickly find out from looking at the signal that it is in fact digital (and binary), but will take some time to figure out how to decode it to a bitstream. Once they have a bitstream, they still have to figure out things like our text standard (the alphabet is probably not in the stream, you're supposed to have that on your decoder) and audio/video codecs. Assuming they have at least our intelligence, it'll take them a number of years. Probably a decade or so.
Obviously if they find after many years they've been working on an encrypted HBO channel, they may have to start all over again. Encryption is possibly impossible to break when you've never seen a key. (hackers on earth readily have access to the smartcards and can "simply" extract the keys. aliens can't order smartcards)

I bet interlacing will also be great fun for them.
Absolutely impossible to figure out why the hell we did that when you don't know our technology.
