Besides digital audio and digital video transmission, DVB also defines data connections (DVB-DATA - EN 301 192) with return channels (DVB-RC) for several media (DECT, GSM, PSTN/ISDN, satellite etc.) and protocols (DVB-IPTV: Internet Protocol; DVB-NPI: network protocol independent).
Older technologies such as teletext (DVB-TXT) and vertical blanking interval data (DVB-VBI) are also supported by the standards to ease conversion. However, for many applications more advanced alternatives like DVB-SUB for subtitling are available.

Famous quotes containing the word content:
“I have sometimes seen women, who would have been sensible enough, if they would have been content not to be called women of sense—but by aiming at what they had not, they only proved absurd—for sense cannot be counterfeited.”
—Horace Walpole (1717–1797)
“Quintilian [educational writer in Rome about A.D. 100] hoped that teachers would be sensitive to individual differences of temperament and ability. . . . Beating, he thought, was usually unnecessary. A teacher who had made the effort to understand his pupil’s individual needs and character could probably dispense with it: “I will content myself with saying that children are helpless and easily victimized, and that therefore no one should be given unlimited power over them.””
—C. John Sommerville (20th century)
“Perchance the time will come when we shall not be content to go back and forth upon a raft to some huge Homeric or Shakespearean Indiaman that lies upon the reef, but build a bark out of that wreck and others that are buried in the sands of this desolate island, and such new timber as may be required, in which to sail away to whole new worlds of light and life, where our friends are.”
—Henry David Thoreau (1817–1862)
