Your remote control has an infrared LED in the front of the unit. Because it's infrared, you can't see it, but if you point it at a video camera or a black and white camera, it's possible to see it light up. That's because the cameras can see a wider light spectrum than can the human eye.

In the remote is a microchip which controls the LED in response to the buttons you push. Each button causes the LED to pulse at a certain frequency.

In the television, is a similar computer chip and an infrared sensor which decodes these pulses and translates them into commands, which the computer chip then sends to the various sections of the TV that's involved. For instance, the volume level, brightness, etc.

I know it's a basic answer, but it's not really all that complicated. Various manufacturers have their own coding scheme and it's quite possible for a remote from one brand to operate some functions on another brand of TV, VCR, or DVD player.
