Digital Cable Channels
Digital television receivers with integrated QAM tuners use ATSC conventions for numbering channels; unlabelled channels would appear as a main channel number, separated by a dot or dash, then a digital subchannel number. For instance, this may display as a physical converter channel number, a dot or dash, then a virtual channel number as it appeared on a digital cable set-top box. As there is no requirement that any specific convention be used to number digital or virtual channels, numbering is at the discretion of the cable operator. Digital cable channels are often numbered starting at 100 or 200, but these are virtual channel numbers and do not correspond to used frequencies.

Famous quotes containing the words cable and/or channels:
“To be where little cable cars climb halfway to the stars.”
—Douglass Cross (b. 1920)
“It is worth the while to detect new faculties in man,—he is so much the more divine; and anything that fairly excites our admiration expands us. The Indian, who can find his way so wonderfully in the woods, possesses an intelligence which the white man does not,—and it increases my own capacity, as well as faith, to observe it. I rejoice to find that intelligence flows in other channels than I knew. It redeems for me portions of what seemed brutish before.”
—Henry David Thoreau (1817–1862)
