Something about DSD and Super Audio CD in there, but no HDMI input. Probably just "upsampling to", but then it says something about "transport" as well -- so maybe they've figured out a way to transmit DSD files over USB?
Yeah really, I don't get that either.
I particularly enjoyed this sentence (from google translate): I don't know what it is, but it's the first DAC I know of that can be used as a Dejitarupurianpu. Perhaps Dinny is a Dejitarupurianputa?
