Does my remote controll have an infrared LED?

Question

I am wondering: How can the signal of my remote controll reach the TV if it is actually an infrared signal? Do I have some different technologie? Can I not buy one of these fancy remote controller that work with every TV?

Thanks for helping out, you save my Xmas

Answer 1

I am willing to bet (but am not completely sure) that the LED pulses, which can be interpreted digitally, to perform the different actions (how else would the TV "know" to adjust volume, channel, ect?). The universal remotes would simply have all those different coding systems preprogrammed into it (notice how you have to select one with a universal remote). You could probably figure it out for sure by probing the input trace to the LED with an oscilliscope and enter in various commands, but who has the time right?

Answer 2

Yes, the remote works using an infrared LED and yes, you can get a universal remote.

you are able to no longer. properly, in line with probability you are able to, regardless of the undeniable fact that it relies upon on the distant itself. the clarification is warmth dissipation. ANY LED calls for a undeniable quantity of contemporary to generate easy. The score of the LED is desperate by potential of the quantity of contemporary it could cope with whilst contemporary is consistently utilized. a common LED will cope with everywhere from 10 to one hundred MA of contemporary indefinitely. the element is, to get the type they DO, they overdrive the LED by potential of everywhere as much as a factor of 10 or extra. the clarification why the LED does no longer burn up from overcurrent is that the flexibility is pulsed to the LED. So, even nonetheless the present would be as much as one thousand MA, 10x the max contemporary score, the era of the heart beat is so short that no longer adequate warmth is progressed to burn out the LED. it is not voltage that burns out a LED (nonetheless intense voltage CAN paintings like lightning and "leap" for the era of or "punch via" an insulating boundary), however the warmth dissipation interior the semi-conductor junction interior the diode. short pulses of intense contemporary do no longer strengthen adequate warmth to soften the junction. I as quickly as used a modulated IR beam to establish a 2 way communications link between 2 properties 4 hundred yards aside by potential of overdriving the LEDS far into the purple as far through fact the specs have been worried, and using lenses to concentration the beam. I actually desperate the pulsed contemporary which might burn out the LED I deliberate on using and then dialed it lower back by potential of 20% My height contemporary replaced into on the edge of two.5 AMPS right into a diode rated at 200 MA. What you are able to evaluate is an IR filter out in front of the IR receiver port. by potential of blockading out ambient easy, you are able to keep away from the sensor being "swamped" by potential of ambient easy which will decrease the sensitivity. think of headlights right here. you spot them plenty extra at evening than during the day through ambient easy point. an identical applies to IR remotes.

buy an all in one remote. there amazing.
