In almost all cases a microcontroller.

 

An IR remote uses IR LED to transmit the signal. If you want to see that, just check the front of your remote, view it through a camera, and when you press a button, you should see a purplish light blink.

The signal is usually transmitted at a frequency of 36Khz or 38Khz. Once you have found the frequency at which the signal is being transmitted, use a TSOP1738 or a TSOP1736 to detect the signal. in TSOP17XX, 'XX' denotes the frequency it detects.

the signal is transmitted using a protocol. For example, most Philips remote controls used to follow the RC5 protocol. the newer ones are according to the RC6 protocol.

Similarly Samsung will also have a protocol. You will have to find that out. You'll probably get it somewhere on the internet.

 

Hello,

The links on this page from the EDUCYPEDIA will give you a lot of information on the RC protocols:
