Yes, HDMI-CEC is the control capability that is a part of the HDMI spec. It allows HDMI devices to control each other. For example, if you have an HDMI-CEC capable Blu Ray player, an HDMI-CEC AVR and a Smart TV, they will control one another in certain circumstances. If you power on one, it will likely power on all of the devices. If you use the volume adjustment on your TV remote and HDMI-CEC is enabled, it will change the volume on your AVR.
Audio Return Channel, or ARC is a part of HDMI-CEC control. ARC capable devices can send AND receive audio through ARC but HDMI-CEC must be enabled. I had to do this on my F6300 and my Denon 1912 in order to get the F6300 to send audio to my speakers through the Denon AVR when watching content from the smart menu of my TV (Netflix, youtube, Spotify etc)
Enabling HDMI-CEC on your devices will create some annoying quirks. My tv likes to take control of my AVR when I power it on and automatically turn my AVR input to "TV" so that the smart hub will send audio to the AVR. But 90% of the time, I use my PS3 for content (Blu Ray, Netflix, Amazon Prime, games etc) so for a while I would have to manually switch my AVR back to PS3 (BD) input after power on even though my Harmony Remote already sent the signal to go to the PS3 input....the smart TV would take control and make the AVR switch to "TV" input because obviously the SmartTV takes precedence. So I eventually figured out that if I turn on my PS3's HDMI-CEC, when I power everything on and the SmartTV tries to take control, all I have to so is fiddle with my PS3 controller and the PS3 then takes over the AVR and makes it switch to the PS3 input. That poor Denon AVR is everybody's bitch.
it was annoying until I figured that out. Now it's just a little quirk. It doesn't really interfere with my ability to watch content, but until I figured that out I was pulling my hair out. LOL!
