The url below points to a new Web page I've created called 'HDMI CEC Guide' that will cover all things HDMI-CEC related. The 'HDMI CEC Guide' page is not about our CEC software but will be focused on universally useful bits of information to do with HDMI-CEC in general. I'm still dumping my scribbled notes into the page so expect it to grow considerably as I do that (I have far more scribbled notes than even I expected!).

All the best

PS If you spot any mistakes or have something you think I should add let me know. Likewise contact me if you have HDMI-CEC related questions that are not answered by the 'HDMI CEC Guide'
