What does cec

What is CEC? What are the disadvantages of CEC? Not all devices support CEC and there are huge inconsistencies between its functionality between manufacturers and devices. It can cause problems in multi-screen distribution systems where AV splitters or matrices are used as conflicts such as turning off one screen can also turn off another screen on the system. The simple fix to this however is to turn off CEC in the device settings.

An additional advantage is that, in contrast to analogue picture and tone which is always susceptible to disruption, signals supported by HDMI are transmitted without interference and in top quality.

Note: The only thing that might interfere with the quality of the signal transmission is the length of the HDMI cable. Unlike analogue signals which hold up well over large distances, digital signals run over HDMI cables have their limits. As a rule of thumb, the best signal quality can be attained by a cable length of no more than 5 meters and transmission without disruption can be expected with cables up to 20 meters in length.

After 20 meters, you can expect the signal to degrade and the picture and sound quality to greatly diminish. A signal booster can help carry signals if cables of this length are necessary. A signal booster , also known as a repeater, is simply a device that is connected to two HDMI cables which regenerates the signal received from the source before passing it on. Because CEC — Consumer Electronics Control — is about controlling all consumer electronics found in a modern living room across all devices.

The manufacturers have not only hesitantly implemented CEC, but have also confused consumers with different designations — even though CEC was originally intended as a cross-manufacturer connection.
