After all, DVB in this instance is the name of the Linux API used to 
access the card, not the TV standard--just like V4L is the name of the 
Linux API used to access an "Analog V4L capture card".  :)

And, as a point of interest that no user is likely to know--let alone 
intuit from "the other answers on screen," this is also why it's "DVB 
DTV capture card (v3.x)"--because the Linux DVB API is at version 3.x.  
The DVB TV standard, however, is just coming up on the 2nd generation 
(DVB-S2, DVB-T2, DVB-C2).  That said, not only do the 1st gen standards 
use versions such as "ETSI EN 300 744 V1.6.1 (2009-01), Digital Video 
Broadcasting (DVB);Framing structure, channel coding and modulation for 
digital terrestrial television" and "ETSI TS 101 154 V1.10.1 (2011-06), 
Digital Video Broadcasting (DVB);Specification for the use of Video and 
Audio Coding in Broadcasting Applications based on the MPEG-2 Transport 
Stream" (i.e. 1.x versions), but also the 2nd-gen DVB uses versions such 
as "ETSI EN 302 755 V1.2.1 (2011-02), Digital Video Broadcasting 
(DVB);Frame structure channel coding and modulation for a second 
generation digital terrestrial television broadcasting system (DVB-T2)" 
and "ETSI TS 102 831 V1.1.1 (2010-10), Digital Video Broadcasting 
(DVB);Implementation guidelines for a second generation digital 
terrestrial television broadcasting system (DVB-T2)", and such (also 1.x
