- soylentcola 4y agoYep. Should be labeled CEC unless the TV's UI hides that behind "user friendly" naming. I also have mine set to turn on/off the AV receiver with the TV, but it can be disabled. Only drawback is that you then need to remember to turn off the receiver.
- zerocrates 4y agoThough the device on the other end may not cooperate, like if it's playing something that uses HDCP it might stop playing when there's no display on the other end of the connection to handshake with. No idea if this is a problem with an Apple TV though.
- yellowapple 4y ago> like if it's playing something that uses HDCP it might stop playing when there's no display on the other end of the connection to handshake with My understanding is that HDMI switches/receivers do the handshakes themselves, specifically to avoid this problem.
- zerocrates 4y agoThey can't just totally do it, at least: then the last hop to the actual display would be decrypted, sort of ruining the whole point of HDCP. My understanding is more that a receiver is just a passthrough for the communication between the source and the display. Though I'm surely oversimplifying.
- yellowapple 4y agoThe receiver could always reencrypt (and usually does, IIUC; signaling this is the point of the "repeater bit" in the protocol). If it was just a dumb passthrough, then there wouldn't be much need to advertise HDCP compatibility in the first place.
- zerocrates 4y agoGood point.
- yellowapple 4y agoIn addition, the receiver doesn't necessarily need to obey CEC signals from the TV. If my TV's sending any, my receiver sure ain't noticing.
- rcme 4y agoOn my TV, this happens with only one of the HDMI ports.
