Answer:
When you use your control remote, you can see that there is not a "material" thing that comes out of the control remote and goes to the TV, but there is actually energy that comes from the control remote (and this is why your control remote needs battery)
This energy is called an "electromagnetic wave" usually in the infrared range, this means that the energy that comes from the control remote has less energy than the visible red light (and this is why we can not see the light that comes out of the control remote), and this "signal" is read by the TV, in order to change of channel or change the volume.
You even can see that there is a sort of light (electromagnetic wave) coming out from it if you point with a camera to the small bulb that is in the front of the control remote.
