Gents,

does B&O support the CEC protocol over HDMI?

This will allow the TV to send a command to the STB that tells it to turn off. This is important as it will reduce the amount of used bandwidth when TV's are off. If this works, turning the TV off will turn the STB off which will release the bandwidth.

I suspect so; but I also suspect the implementation varies by BeoVision.

On my BV8-32 I have to use menus to switch off the Apple TV before I put the BV to stand-by.

On my BV8-40 I usually just have to put it to stand-by, and a second latter its ATV goes to stand-by.

Both ATVs have HDMI cables, both are Apple HDMI cables although possibly a year apart and so maybe different HDMI standards, one ATV is a 720 model - the other is the 1080 model (a year older).

As far as I know B&O do not support HDMI CEC. They use their PUC technology to control external devices.

Then the different behaviour I see is the result of different PUC implementations

Or different versions of the same implementation

So 3!!! possibilities for my differences

Anything is possible in the wonderful world of B&O

I hope, they do not support HDMI CEC.

Would always turn on the main BV, when I`m using the HDMI devices from linkrooms....

On my Beosystem 3, when you are connecting up sources to be controlled by the PUC,  you get 4 choices 

1. Off at source change.

2. Off at TV Standby 

3. Always on

4. Manual control 

This is probably why you have differences.

CEC does not always work that well - at least on the set I have it doesn't always map keys, fails to switch things on or off and omits key functions. The B&O PUC system is much better.

I still have to test it because I do not have a CEC enabled device currently, but my dealer told if you connect such a device to a LG HDMI port (not the ones at the Soundcenter) sitting on top of a Harmony or Stage, you can remote control the device with your Beoremote One. So should work with an Eclipse as well.

When my Harmony will be up and running I will give it a try.

Correct. Rather frustrating, because these kind of spammers usually only make that one post, so banning & deleting is mostly just fruitless work Angry
