| May 17, 2014 at 14:36 | comment | added | Passerby | @user35075 the hdmi cec protocol can do that. And my tv has an led that blinks in respond to seeing valid ir codes (even if the code does nothing). But the real solution to that is what tivo boxes do. They run the ir led on a cable and tape it to the tvs ir sensor window. | |
| May 17, 2014 at 14:31 | comment | added | Passerby | Most tvs have a discreete CC code, even if your factory remote doesn't have a button. Send all 255 remote codes one by one to find it. And most Universal Remote Controls, especially JP1 types, can do macros with ten buttons easily. A nice easy to find and often free one is the large Comcast remotes. | |
| May 17, 2014 at 13:35 | comment | added | aja | Perhaps not the easiest, but an alternative approach is to use your Arduino to record all the existing remote sequences and then systematically try transmitting all the intervening ones. You may get lucky and discover an undocumented "toggle captions" function code. | |

Edit: Made title more precise (mentioning the TO wants to simulate a remote) (actualy sub-questions left away as the Q it's not clear enough [to me])

What's your actual problem? You're asking for 1) modulation and 2) you mentioned you were using an Arduino and "it's such an over-kill". Why would it be overkill? Take one step backward, is 1s boot time really a problem for your setup? You're saving yourself ~10s manual, annoying button presses! In another project I used a 555 for the carrier and modulated it using the Arduino. Generating the carrier in software is also fine since - in your case - sequencing those keys is the only thing the microcontroller will do - isn't it?

| May 16, 2014 at 15:38 | comment | added | user35075 | Every time I've thought about solving this problem myself (for my 90 year old mother's TV) I've always been frustrated by the inability to query the status of the TV. Specifically: - My Arduino "presses" the controller button. - Did the TV actually "see" the IR pulse? - Did the TV correctly change the channel, etc? THAT feedback seems to be the heart of these TV automation problems. When TV manufactureres start manufacturing TVs with a queryable "Status" port, that'll be a game-changer. | |
