Dolby Atmos and DTS-X?

My understanding is that only blu ray disks are capable of transmitting the Dolby atmos signal...in discrete form....Over satellite and the internet they are using Dolby digital plus which is a form of Dolby digital only with more compression and it is also only a 5.1 stream...how ever a Dolby atmos receiver can take a 5.1 signal and change it into a signal that will utilize all your speakers...I don't believe it is true Dolby Atmos though and I am having a hard time believing that even the Dolby Atmos blu ray disks are really Dolby Atmos, because from my understanding the mixing process is completely different for Dolby Atmos compared to surround ...its object and location oriented as compared to surround which is atmospheric oriented sound which is a whole different process and objective from what I've read about...So I am having problems understanding how Dolby Atmos is compatible with surround at all... unless they are programing two different sound tracks one for Atmos and one for surround....because the process is suppose to be completely different...

If your device does not have an Atmos standard decoder built into it, and the required extra amplifiers & speakers, why do you think you are going to be able to decode Atmos disks properly? I own a single speaker radio and do not expect it to decode and play six channel surround sound through non existent speakers.. Doesn't make it a bad radio, just makes it the monaural radio it is..
