    NTSC is the video format used in the USA and a few other places (Japan and Mexico are both NTSC also I believe). It is a specific frame rate and resolution- it is basically the format you know as video (29.97 frames per second, interlaced 60 fields, 480 lines).
    PAL is the format used in Europe and other areas. Their video format is different than the US format, it consists of 576 lines and is 25 frames per second.
    There is also a third format, SECAM that is used in some countries.
    These differing systems make it impossible to watch European video sources on USA TVs- the video format itself, regardless of what the carrier (DVD, VHS, etc)- is simply a different frame rate and resolution than out TV monitors are designed to work with.
    I believe that NTSC stands for Nation Television Standards Commission (or Committee)- named after the organization who developed the standard at the advent of television broadcasts... the same way SMPTE time code is named after the group that developed it (Society of Motion Picture and Television Engineers).
    Some people joke that NTSC stands for "Never Twice the Same Color".
    I'm not sure where the distinction "PAL" originated- think it has something to do with 'P***** alternating lines'.
    Here's some info in case you want all the specifics:
