D-BOX is a haptic motion technology format from D-BOX Technologies Inc. It's not part of the Blu-ray specifications but it's an optional peripheral feature.

For Blu-ray, D-BOX is often used for providing haptic motion effects for movies. It's motion code is installed from disc inside a D-Box motion controller with a BD drive (or downloaded from D-Box's web server if it does not have a BD drive). The motion controller is connected to a D-Box chair/seat. Then the disc inserted to the Blu-ray player and played in sync with your D-Box motion controller.

The Majority of D-BOX enabled BD titles (on-disc) are from Universal and Twentieth Century Fox (Pre-2019). BD titles from Disney, Warner Bros. and Sony are available to download from D-BOX's web servers.

1. Seating - For D-Box seating, you have three options:
   1. New Seating - You can purchase seating with the D-Box hardware already installed. This includes SRR-J-131, SRR-J-132, SRR-J-133, SRR-J-231, SRR-J-232 or SRR-J-233.
   2. Existing Seating - You can purchase frames that include the D-Box hardware that will retro-fit your existing seating. These models include SRP-130, SRP-230, SRP-330 and SRP-530.
   3. Custom Seating (SRR Series) - D-BOX has worked with various seating manufactures to ensure that they build seating that can easily fit the D-BOX hardware. Those manufactures include CDGI, Cineak, Cinematech, Continental Seating, Design NS, Fortress Seating, Jaymar, and United Leather.
      
      
2. Motion Controller - This hardware is to motion as a surround sound receiver is to audio. Every D-Box system MUST include one of these. This controller includes a BD-ROM drive for loading D-Box codes from BDs that already include D-BOX motion codes. It is also connected to your internet connection for downloading codes directly from D-BOX for movies that do not include the codes on the BD. For Blu-Ray support, you have two options:
   1. Standalone Series - Series IV BD - This controller has a built-in BD-ROM drive.
   2. PC Based - From my understanding, a less expensive option is to dedicate a PC, with a built-in BD-ROM drive, as your controller.
      
3. Finally, you need a Blu-Ray player. Any Blu-Ray player with a Digital Optical or Digital Coax output will work. However, there are issues to this:
   1. If you simply want to have motion and lossy audio, you may use any Blu-Ray player with Digital Optical or Digital Coax output. Note that your Blu-Ray player's audio settings will need to be set to bitstream and NOT PCM.
   2. If you want to have motion and lossless audio, you will need a Blu-Ray player that will output audio via HDMI and Digital Optical/Digital Coax at the same time. The Blu-Ray player needs to send the lossless audio track to your surround sound receiver via HDMI and the lossy Dolby Digital or DTS audio track will connect to the D-Box controller (standalone or PC based) via Digital Optical or Digital Coax.

Motion Code Files

D-BOX uses proprietary files for it's motion codes, .KLK,.IID,.SYN. They are stored on it's own ZIP folder directory (for each language and codec) outside of the BDMV directory. It is unknown on what these files do in particular. Outside of the ZIP folder(s), there's a XML file called FilmIndex.XML.
