How can TVs recognize the type of device connected via HDMI?

I connected a Playstation 3 to my Samsung TV via the "HDMI 1" connection. After I started the Playstation, the name of the HDMI source in the TV was automatically renamed to "HDMI 1 - Playstation 3". How does the TV recognize that there's currently a Playstation 3 plugged in and not a laptop?

HDMI is digital. Ultimately, this means that there are always two computer chips communicating with each other and they also transmit what kind of devices they are.

The feature is called Consumer Electronics Control (ECE). Samsung has its own name for it - they call it "Anynet +".
Among other things, ECE enables the "Device OSD Name Transfer" function, which transfers the device name to the television.
