Display Control Channel (DCC) is an advanced method of implementing an on-screen display (OSD) technology on KVM switches.
On-screen display technology used on KVM switches is used to show control and selection functions pertaining to the KVM, such as what port is selected, and what ports have computers connected. OSD is typically broadcast on top of the selected channel's existing display. Because of this, the quality of the OSD's images is inconsistent and unreliable. Its size and positioning depend on the video resolution of each individual system connected.
On KVMs with a DCC controlling menu, the configuration selection is displayed on a dedicated independent video channel. The quality of the controlling menu is more secure and reliable because of this. The DCC method of broadcasting this information via an independent channel allows for greater functionality and more programming possibilities in the future.
Display Control Channel is patented by Connectpro.
Famous quotes containing the words display, control and/or channel:
“Housekeeping is not beautiful; it cheers and raises neither the husband, the wife, nor the child; neither the host nor the guest; it oppresses women. A house kept to the end of prudence is laborious without joy; a house kept to the end of display is impossible to all but a few women, and their success is dearly bought.”
—Ralph Waldo Emerson (1803–1882)
“The glance is natural magic. The mysterious communication established across a house between two entire strangers, moves all the springs of wonder. The communication by the glance is in the greatest part not subject to the control of the will. It is the bodily symbol of identity with nature. We look into the eyes to know if this other form is another self, and the eyes will not lie, but make a faithful confession what inhabitant is there.”
—Ralph Waldo Emerson (1803–1882)
“This is what the Church is said to want, not party men, but sensible, temperate, sober, well-judging persons, to guide it through the channel of no-meaning, between the Scylla and Charybdis of Aye and No.”
—Cardinal John Henry Newman (1801–1890)
