viera link help

[Matsy]

Have a panasonic tx-p42st60b, which has CEC support via HDMI port 2.
Have OpenElec on my eMachine from years ago, works fine and should support CEC (controlling xmbc with tv remote)
However, Viera Link, does nothing, on the options it doesnt even have many options under Viera link, just on and off.

Any help with this?

Viera link is "basically" Panasonic's name for CEC (although not actually the same). If you were to have 2 panasonic products they would work fine together as they both use the same signals to represent the appropriate control, however you thow something else in the mix you are relying on one of the devices to realise what the other-one is. Then hoping that it can send the correct signal. Newer TV's generally use the full CEC spec (then some of there own special stuff to work with there own models)

 

It was very common a year or 2 ago for other brand devices to not work with each other, now most stuff plays friendly there are still some issues.

 

A pretty good example is LG TV's from 2013 and before didn't work with CEC to a PS3 but would work with most other devices.

 

CEC requires HDMI 1.2a (or more commonly 1.3 with a full feature set)

CEC isn't common on intergrated chipsets and only on some dedicated graphics cards.

Even if you have CEC capable GPU/chipset you are then relying on the software to even be listening for the signal which I've not seen any consumer software that is.

 

You can however buy this adapter and install this driver to listen for inputs

 

Viera link only has on and off because that is all that is really relevant. If on doesn't work then the devices connected (if turned on at both ends) are not capable of control over HDMI with each other.

 

You would turn it off if a button had an incorrect output at the other end (Like turning the volume up on your TV turned off the linked device)

Thanks for that.

 

Where I go into the CEC options on xbmc (peripherals) is grayed out anyway for some reason, I dont know why....

 

Would it be easier (and cheaper) to just buy a Rasberry pi and put kodo on it? apparently those can already use CEC, as its integrated?

Also £29 for a tiny adapter, they sure are getting a massive mark-up on those.

you would be able to do it with a Pi but I'm not sure how you would go about setting it up.

Do you have a phone with an IR blaster you may be able to control both from that?
