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)
““Have we any control over being born?,” my friend asked in despair. “No, the job is done for us while we’re sleeping, so to speak, and when we wake up everything is all set. We merely appear, like an ornate celebrity wheeled out in a wheelchair.” “I don’t remember,” my friend claimed. “No need to,” I said: “what need have us free-loaders for any special alertness? We’re done for.””
—Marvin Cohen, U.S. author and humorist. The Self-Devoted Friend, New Directions (1967)
“For, rightly, every man is a channel through which heaven floweth, and, whilst I fancied I was criticising him, I was censuring or rather terminating my own soul.”
—Ralph Waldo Emerson (1803–1882)
