While researching
for my previous two-part article (Part 1, Part 2), I stumbled across something interesting that
I hadn't encountered before. It ended up on the cutting room floor
due to space, but I thought it was worth exploring further in this
diverting little side topic. If you could just scooch over a bit
closer and allow me to whisper conspiratorially in your ear: the
MIL-CD enhanced audio disc might not have been the only special
multimedia format that Sega invented especially for the Dreamcast - they may have also toyed with the idea of snubbing the DVD Consortium by producing their own proprietary digital video disc format for movies and films. Hush, stifle your gasp, they'll hear you.

| N-n-no Mr. Bighead, I didn't tell them. Honest. |
You may have noticed some logos during the start up sequence of many Dreamcast games for ADX and Sofdec. These are the CRI developed middleware tools for sound compression and multi-streaming video respectively. ADX allowed for CD quality audio to be compressed and encoded into the high-density GD-ROM layer (as opposed to standard 'red book' audio tracks). Sofdec was an enhanced version of the MPEG-1 video standard which not only encoded standard FMV cut-scenes into games, but was also tailored towards providing 3D game designers with access to some pretty swish graphical trickery. Video files could be rendered as textures over 3D objects and they could also utilise full alpha blending for effects such as explosions, fire and smoke. Multiple video files could be played synchronously or asynchronously and they could also be looped and stitched together seamlessly. All in all, Sofdec is probably a substantial reason as to why Dreamcast games looked so good (and have aged well like fine wines too). CRIWARE, as they are now known, continue to flog their wares to this day, proudly waving their flag in recent games like Bungie's Destiny.
