Several torrents are noted as (Upconvert)
Example.
Sirenia - Perils Of The Deep Blue (Limited Edition) (Upconvert)

What does (Upconvert)mean on a torrent like this?
What is the purpose?
Is it a re-encoded lower bitrate to a higher? That is a waste of disk space and just stupid, or is it something else?

Please explain.
