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
KTX2

KTX2 Strengths

  • Universal hardware compatibility: write once, transcode anywhere to the target GPU's preferred format (ASTC, BC7, PVRTC, etc.)
  • Drastically reduces transmission size over networks thanks to Basis Universal and Zstandard supercompression
  • Seamless integration with the glTF ecosystem for optimized 3D asset delivery
Limitations
  • Requires WebAssembly (Wasm) decoders and JavaScript loaders for web viewing, increasing initial application payload slightly
  • Encoding textures into high-quality Basis Universal UASTC can be computationally intensive and slow
  • Zero support in traditional 2D image viewers or native OS previews

When to choose which format

DECE-Graphic
Use DECE-Graphic when…
  • UltraViolet Movie Cover Art
  • Common File Format (CFF) Asset Manifests
  • Legacy DRM Ecosystems
KTX2
Use KTX2 when…
  • glTF 3D Models (KHR_texture_basisu)
  • WebGPU and WebGL Applications
  • Game Engines (Unity, Unreal, Godot)
  • Augmented and Virtual Reality (AR/VR)
