What they transmit depend on the used protocol. With NEC and RC5 (currently, the most common protocols), they transmit only address (TV, VCR, SAT) and command. If you have two IR's that not fully follow RC5 standard, they may use distinct addresses. So, if you're lucky enough, you'll be able to guess the IR vendor, based on the 8 bit address code. I think that you can get the vendor only with RC6 IR's on some modes. In the case of RC6, as pointed by Andy, there are some patents envolved, meaning that we probably will need to decode it on userspace, except if someone can get the proper patent rights for its used on Linux.
