Controlling TV via HDMI from PC via C#

Hi,
I would like to control my Samsung TV from my computer (Windows 7). I´ve got it connected via HDMI (my videocard has direct HDMI-out). On the computer, there´s running a C# program, that plays movies from the computer to TV and automatically switches sound and video output to TV. Now I want to improve the program and I want to automatically turn the TV on and switch TV video input from aerial to HDMI-in, when user press the button "Play movie".

The TV supports Samsung Anynet+ - standard, that supports one remote control for more Samsung devices (You just control your TV, DVD, camera and whatever via one remote control). Maybe it would be useful when the computer would looks like Samsung device - it is given by software that is running on the computer. If it would be some Samsung software, TV would thinks that PC is Samsung device and I would maybe use some anynet+ messages to control my TV. This is just one my suggestion. I would prefer winAPI of course, but I´m not sure if it´s exists.

I could maybe try to send a specific bits to HDMI output...

Please, does anybody know about friendlier solutions than these two suggestions?

Thank you!

I thought this to be really interesting; especially as i'm builing a HTPC. As far as i can tell with the reading i've done so far the answer is: you can't... Or rather not directly. What you are looking for is getting access to the HDMI CEC bus. As far as i could tell the PC HDMI interface does not support direct access to the bus (maybe there are linux drivers that can). There are devices or DIY schemetics that split the HDMI to USB. Using the USB you can send or receive the CEC commands.

I hope someone has a way to directly access the bus from the PC's HDMI.

Programmatically controlling the HDMI connected TV from a PC requires the TV to support HDMI CEC (Consumer Electronics Control), which you say your Samsung does, but it also requires that your PC hardware supports it.

CEC uses one signal wire on the HDMI cable (plus a ground) for very low speed (by computer standards) signaling to or from (on the same wire) the TV. That wire may or may not be connected or used on your PC video interface. I've found it to be hard to get information on whether or how various PC manufacturers support the CEC connection.
