Which Dolby technologies are multichannel?

[unnameduser]

From my understading, this is what I've learned.
Dolby Pro Logic II can take only 2 channels and turns it into 5.1 channels.
Dolby Pro Logic IIx can take only a 5.1 channel connection and creates either 6.1 or 7.1 channels.
Is there anything that takes 7.1 channels and ouputs 7.1 channels.
Dolby TrueHD ?
Dolby is very poor at stating exactly what the technologies do on their website. Is all of this correct?

Any complete devices you find is comprises with hardware and software but package in one like a reciever.

So If you have the hardware and fully implemented software, then yes. it will work.
