With all that stuff able to come out of one port, it sounds like a docking station connector!
As for a single cable going from the laptop to a TV, it would likely be VGA (15 pins, squarish shape) or S-Video (4 or 9 pins, round like a PS/2 plug). It could also use a composite/RCA-style wire (round, one pin) to a TV, depending on the computer.
EDIT - then again, in Europe don't you guys have SCART connectors too? I'm not familiar with them, because we don't have them in Canada, but SCART supports a whack of data modes. Perhaps tell us what this connector looks like?
Is THIS it?
