</div>Which is why its confusing as DTH is satellite, which is less direct.<br></blockquote></div><br>DTH/DTT describe how signals reach consumers, they are not standards.
DVB-* describe specific standards. I.e. DVB-S is one specific form of
DTH broadcasting.<br>
<br>DTH was originally meant to differentiate signals from the satellite that were intended for end-users from those intended for network retransmission (i.e. feeds). In that context it makes sense: those signals go directly to the home, other signals on the same satellite go to a network who then retransmit them via terrestrial broadcast or cable. The term predates DVB.<br>
