P frames are differences from the previous I frame.
B frames are differences from the preceding and following frames,
whether they be I or P or B.
In other words, you can't play a B frame at all without all the data
between one I frame and the next.
Ever try to skip forward and back in a youtube video? Those jumps
*there* are the I frames (or whatever equivalent). P frames need the
previous I frame (and maybe previous P frames? I don't remember) and B
frames need all the data between two I frames.

Yep. How long do you think DSL and MPEG1 has been around? :-)
