It will depend entirely upon what unencrypted content your provider 
pours down the 'wire'.
Content can be delivered by digital or analog streams.
Content can be SD or HD.
Some digital content is encrypted and you need a set top box.
Some digital content is not encrypted (although QAM256 encoded on cable').
The FCC mandates that cablecos provide the local off-air channels 
through an unencrypted feed (ie: not 'premium content').
So you will get your local off-air available channels as HD content, 
unencrypted, to the extent that the local network affiliates broadcast HD.
Other digital channels may bne HD or SD as the cableco decides.

You will probably still need the 'cable box' as it probably does the 
optical to wire conversion required to split out the tv signals.
