A previous article mentioned the limited bandwidth in the color
channels (composite color video). The 500 kHz limitation in the Q
channel, however, is fully sufficient for the intended purpose:  the Q
channel is (essentially) blue, and the human eye just plain can't see
blue change much faster than the 500kHz limit provides.  And I would
guess that, if you're building your own system (send and receive) that
you could extend the bandwidth of the channels, both I & Q, and see if
it looks any better.  The next trick is to get a display tube worthy of
the electronics you put behind it...
