Technology HDMI-CEC Consumer Electronic Control what is it
If the TV, Blu-ray player, receiver and other devices support HDMI CEC.
This means that by connecting these devices via HDMI you can control any device using a remote control such as a TV.
But the remote control must support the appropriate commands. Such a remote control, in addition to supporting commands for the TV, should have buttons for watching video forward, pauses, etc.
All televisions of more or less well-known brands support HDMI CEC technology. This feature is added at the software level, the TV broadcasts commands via the HDMI port to other devices. Only the simple name HDMI CEC is commonplace and all manufacturers have called the HDMI CEC standard their own commercial names.

Is HDMI CEC really in demand
HDMI CEC is used by very few users.

With the advent of Internet television, the use of HDMI CEC becomes unclaimed.
But if for example you watch satellite TV, then of course you have configured HDMI CEC, when you turn on the TV, the satellite receiver will turn on, this is certainly convenient.
