I don't think so.  HDTV takes up the full 6 MHz channel for one giant data 
stream.  That data can be multiplexed, divided, into more channels, IF you don't 
want it to be high-resolution.  The overall spectrum savings, as I understand 
it, comes from rearranging the stations' channel assignments to better "pack" 
them in.
