HDMI-CEC

What is CEC?

CEC (Consumer Electronics Control) is the control protocol found in HDMI. Trade names for CEC are Anynet+ (Samsung); Aquos Link (Sharp); BRAVIA Link and BRAVIA Sync (Sony); HDMI-CEC (Hitachi); E-link (AOC); Kuro Link (Pioneer); CE-Link and Regza Link (Toshiba); RIHD (Remote Interactive over HDMI) (Onkyo); RuncoLink (Runco International); SimpLink (LG); HDAVI Control, EZ-Sync, VIERA Link (Panasonic); EasyLink (Philips); and NetCommand for HDMI (Mitsubishi).

All modern televisions and AV-receivers support HDMI-CEC, which is a technology that allows devices to talk with each other over the HDMI cable. UMC comes with CEC which allows control of the UMC input over the standard TV remote that comes with your TV. As buttons are pressed the remote command is sent via the HDMI cable to your UMC device.

Our Media Center System already support HDMI-CEC, allowing you to control them via your television remote control without using the included dedicated remote for the Ultimate Media Center system.

Once you have connected our Ultimate Media Center to your TV and receiver with HDMI you should be able automatically to turn on and off your TV, receivers, and other home theater equipment, control your amplifier's volume, manage your DVD or Blu-Ray player, and redirect the active source on your TV to other equipment, all from one remote control. No line of sight is required and cables can be hidden neatly out of sight!


Using this feature a UMC compatible CEC controller/adapter will send and receive remote key presses to and from your television and AV-receiver via CEC.

CEC allows you to do things such as:

  • Controlling UMC from the TV's remote control
  • Automatically switch to the right TV input device
  • Letting the HTPC control what mode your audio receiver is on when the TV switches on
  • Turning all devices off with one remote
  • Set volume/mute of the receiver
  • And a lot more!


The following is a list of the most commonly used HDMI-CEC commands:

  • One Touch Play allows devices to switch the TV to use it as the active source when playback starts
  • System Standby enables users to switch multiple devices to standby mode with the press of one button
  • Preset Transfer transfers the tuner channel setup to another TV set
  • One Touch Record allows users to record whatever is currently being shown on the HDTV screen on a selected recording device
  • Timer Programming allows users to use the EPG (Electronic Program Guides) that are built into many HDTVs and set-top-boxes to program the timer in recording devices like PVRs and DVRs
  • System Information checks all components for bus addresses and configuration
  • Deck Control allows a component to interrogate and control the operation (play, pause, rewind etc.), of a playback component (Blu-ray or HD DVD player or a Camcorder, etc.)
  • Tuner Control allows a component to control the tuner of another component
  • OSD Display uses the OSD of the TV set to display text
  • Device Menu Control allows a component to control the menu system of another component by passing through the user interface (UI) commands
  • Routing Control controls the switching of signal sources
  • Remote Control Pass Through allows remote control commands to be passed through to other devices within the system
  • Device OSD Name Transfer transfers the preferred device names to the TV set
  • System Audio Control allows the volume of an AV receiver, integrated amplifier or preamplifier to be controlled using any remote control from a suitably equipped device(s) in the system
