DECE-Graphic

DECE-Graphic Strengths

  • Allowed the UltraViolet DRM ecosystem to easily distinguish structural UI/cover graphic assets from actual encrypted video tracks in a Common File Format container
Limitations
  • Completely obsolete since the 2019 shutdown of UltraViolet
  • Unnecessary abstraction, as the underlying files were just standard JPEGs or PNGs
  • Causes modern strict MIME-type validators to fail if they rely on the Content-Type header
FITS

FITS Strengths

  • The undisputed global standard for archiving and sharing astronomical data
  • Self-documenting: Headers are written in plain ASCII, ensuring data is readable decades later regardless of software
  • Supports incredibly high dynamic range, N-dimensional arrays, and complex binary tables
Limitations
  • No support in standard consumer software or web browsers
  • Uncompressed raw FITS files from modern telescopes can be excessively large
  • Does not use standard metadata models like EXIF or XMP, requiring specialized parsers

When to choose which format

DECE-Graphic
Use DECE-Graphic when…
  • UltraViolet Movie Cover Art
  • Common File Format (CFF) Asset Manifests
  • Legacy DRM Ecosystems
FITS
Use FITS when…
  • Astronomy & Astrophysics
  • Space Telescope Data (Hubble, JWST)
  • Scientific Data Archiving
  • Spectroscopy
