I want to connect a linux PC with HDMI output to my (Samsung) TV. This allows to show a screen on the TV.

How can I use the TV's remote as an input device, sent over HDMI to control the PC?

Or in other words, can I make a simple user interface which is shown on the TV and is controlled with the remote control? I mainly imagine using the 4 arrow-buttons and the OK to navigate and choose stuff.

Any links to doc or libraries (Java preferred) are welcome.

Answer 1

The protocol used to send the remote control signals is called CEC. In order to make use of it you will need hardware which supports it, and have drivers for that hardware.

Lacking any more specific information about the hardware you are using, I suggest starting at this page about CEC support on the Raspberry Pi
