Hidden Signals: Not Always Transferred
TV contains many hidden signals. One signal type that is not transferred, except on some very expensive converters, is the closed captioning signal.
Teletext signals do not need to be transferred, but the captioning data stream should be if it is technologically possible to do so.
With HDTV broadcasting, this is less of an issue, for the most part meaning only passing the captioning datastream on to the new source material. However, DVB and ATSC have significantly different captioning datastream types.

Famous quotes containing the words hidden and/or transferred:
“Lap me in soft Lydian airs,
Married to immortal verse,
Such as the meeting soul may pierce
In notes with many a winding bout
Of linked sweetness long drawn out,
With wanton heed and giddy cunning,
The melting voice through mazes running,
Untwisting all the chains that tie
The hidden soul of harmony;”
—John Milton (1608–1674)
“When private men shall act with original views, the lustre will be transferred from the actions of kings to those of gentlemen.”
—Ralph Waldo Emerson (1803–1882)
