Television remote controls use light to communicate with televisions.
Infra-red light is invisible to the human eye but it is a very effective way of sending data across a short distance. To send a message, the light is sent in a pattern of flashes. When the pattern is received by the television and decoded, it will become a number or perhaps a pair of numbers that the television will use to do a specific task. Every button on the remote has a different number value that is encoded into a string of flashes.
Different remote controls use a wide range of different encoded patterns so remotes for one item of equipment won't interfere with other units.

Signals travel from towers to televisions by?
This will be different depending on your location. In most places the signal travels through cables, but in some remote areas satellites and dishes are used
What is Scientific about watching tv?
The TV is created using science, the shows are recorded using science, even the signals are sent from the TV station to your house using science. If you want to go further, the light being emitted by the tv is traveling through the room to your eye. In your eye, rods and cones are translating that light into electrical signals that are then sent to your brain, which decodes those signals into what you see.
How can you get channel wnep 16 2?
I have a TV converter box, I use the remote to scan for available signals and then they are automatically programmed into my remote/system as an available viewing channel.
What is tv remote operating frequency?
It varies form manufacturer to manufacturer. Besides, most TV remote controls work on infrared light signals, pulsed at a specific rate to match the programmed processor in your TV.

Why does your tv send out a signal the first 5 minutes it is on that jams your remote extenders?
Because it is looking for the original remote, so it jams any signals that could distract it from its current task (finding original remote). Is there any way to "turn that off"?
Will a TV remote work through a mesh screen?
It might, but the mesh will cut down on the range and effectiveness of the remote.
When was the remote control invented?
It may have been the Zenith brand, with their Space Commander remote in the late 60's. It operated with a tuning fork instead of infrared signals.
Why does television signals travel through a vacuum?
television signals are communication signals, which can either be radio or microwave signals. These are both part of the electromagnetic spectrum. In the spectrum all the different signal types have some similar properties, including being able to travel through a vacuum, usually because they have a strong enough frequency and wavelength, and they don't need to travel in particles but waves :)
What interferes with remote control signals?
Other radio signals. They can be from many different sources. Walkie-talkies, TV remotes, etc. Pretty much anything the broadcasts has the potential to interfere if the broadcasting channel is close to the signal band of your RC.
What frequency do household remote control electronics operate on?
The frequency of remote controls for the television varies from brand to brand. The ones that do operate using radio frequencies though are all generally low frequencies. Most remote controls today operate using infrared light signals though.
What was the sci-fi TV show where they traveled through time with a remote control?
Sliders
