    Default Consumer Electronics Control (CEC) support in Girder?

    I'm upgrading my home cinema to a new HTPC so I'm the process of re-configuring all my controlled devices, the majority of which I do using serial control in Girder.

    I'm also researching the purchase of an LCD TV that I would like to hook up to my HTPC using HDMI. I noticed that some of the TV's I found have something called Consumer Electronics Control (CEC) over HDMI, which basically allows devices that support CEC to interact with one another.

    In my opinion it would be great if Girder could be used to control HDMI-connected devices using CEC, as well as receiving data/trigger/states from the devices. Imagine the TV telling Girder what channel it's at, and to use the TV remote control for Girder actions. Hopefully this would be easier to set up, would not require an extra port on the TV or PC and no extra wires.

    For a brief intro on CEC:

    That would be awesome indeed. Taking a brief look at the spec it says that support is optional... also that would need support from the video card to be able to write to the CEC channel. I didn't see any APIs for that let me know if you come across anything.

    This device seems to fit. It does not appear to require video API, its a secondary hdmi cable to the TV. this should allow me to turn on my TV with netremote/girder and controll WMC for everything else.

    This device seems to fit. Of course that means I'm going to retry installing Windows 7. I keeping fixing stuff until it's truly broken!It does not appear to require video API, its a secondary hdmi cable to the TV. this should allow me to turn on my TV with netremote/girder and controll WMC for everything else.


    Thanks & Regards

    Support for a remote control protocol looks cool, too bad it reminds me of the also optional implementation of the control protocol in the Scart standard, that only got implemented on a handfull of devices
