Why does foreign TV look different?

Whenever I happen to flip past BBC channels & they're just showing regular shows (not news or sports), the picture just looks really different. I don't know if it's a matter of focus, frame rate, or what, but it just looks...different. It doesn't seem to rub off on movies, though. They look the same.
Anybody? |

| Same thing happens here between soap operas and sitcoms. (Most anyway) |

PAL != NTSC |
we have a winner.
Because the PAL format has greater resolution than NTSC. |

| ok, so it's PAL vs. NTSC, & Tape vs. Film, but what does that actually do? What is the difference that I'm actually seeing? |

PAL vs NTSC
Because the PAL format has greater resolution than NTSC, it is generally accepted as being of higher quality .[2] NTSC receivers have a tint control to perform colour correction manually.
However, the alternation of colour information — Hanover bars — can lead to picture grain on pictures with extreme phase errors even in PAL systems.
A PAL decoder can be seen as a pair of NTSC decoders:
* PAL can be decoded with two "NTSC" decoders.
* By switching between the two NTSC decoders every other line it is possible to decode PAL without a phase delay line or two phase-locked loop (PLL) circuits.
* This works because one decoder receives a colour sub carrier with negated phase in relation to the other decoder. It then negates the phase of that sub carrier when decoding. This leads to smaller phase errors being cancelled out. However a delay line PAL decoder gives superior performance. Some Japanese TVs originally used the dual NTSC method to avoid paying royalty to Telefunken.
* PAL and NTSC have slightly divergent colour spaces, but the colour decoder differences here are ignored.
* The issue of frame rates and colour sub carriers is ignored in this technical explanation. These technical details play no direct role (except as subsystems and physical parameters) to the decoding of the signal.
