How do universal IR remote “codes” work

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite It is easy to find this kind of reference when searching for IR protocols and codes for specific equipment. The actual IR transmission contains far more data than these small codes can hold. What exactly those codes represent? How can 4 digits represent all the commands a device can receive? Are these "codes" references to some standard protocol? How do the universal remote knows the protocol and all the codes the product understands from this small configuration code? I would love to understand more about this technology. For me it seems that every remote is different, and you would have to reverse engineer every message to identify which bit/byte does what. infrared remote-control protocol share | improve this question edited 2 hours ago Passerby 55.2k 4 48 143 asked 2 hours ago Filipe Nicoli 423 3 8 Thank you @Passerby – Filipe Nicoli 1 hour ago

A secret base is built on Mars: is it noticed?

Clash Royale CLAN TAG #URR8PPP up vote 4 down vote favorite 1 A secret society of inventors has been hiding for years. Finally, they have designed their Mars base in the year 2019! Unfortunately, they "borrowed" most of their supplies. If they were to build a glass survival dome say, 200 meters in length, would NASA or any of the other space agencies be able to find it in the next few years? Assuming that no Martian rovers or anything come across the dome, would satellites or telescopes notice the domes, and how long until they do? science-based space secret-society share | improve this question asked 3 hours ago Redwolf Programs 702 1 5 17 How do they get to Mars unnoticed? – Keith Morrison 3 hours ago They hide in a secret compartment in a NASA rocket, but that's not relevant to the question – Redwolf Programs 2 hours ago Many proposed Martian colonies are at least partially underground,
