CD: AAD ADD - UHD: up/down scale - Blu-ray Forum

Soon after the CD was introduced the SPARS CODE
https://en.wikipedia.org/wiki/SPARS_code
was created to provide more information about the
source and mixing method used for the CD.

I think it would be helpful to provide similar information
about UHD Blu-ray discs, specifically, was the UHD
content produced using upscaling and/or downscaling
of the source material.

(maybe the content produces don't want to reveal
that a UHD Blu-ray disc used upscaled content)

In the end the SPARS code said nothing about the quality and disappeared from most CDs during the 90ies. Especially DDD was often used to indicate quality but AAD can sound just as good - or better.

The same can be said about UHD. A 4K master doesn't automatically result in high quality and 2K masters are not bad in general.
