Descriptive Video Exchange (DVX)

The Descriptive Video Exchange (DVX) –

allowed sighted video viewers to verbally describe what they see in a video, and seamlessly share those description clips and their synchronization information over the Internet, thus increasing widespread accessibility of video for blind and visually-impaired viewers. The DVX platform operated on a Client/Server model that stores all the description clips, the synchronization information, and the unique identifiers for the original video content on a dedicated server. This innovative technology permitted a wiki-style crowd-sourcing of video description in a completely new way, opening the door to amateur description provided for any video content, and distributed to anyone without modifying or redistributing the original video in any way.

 
Based on this technology, the Miele Lab at Smith-Kettlewell conducted a program of rigorous research to evaluate:
  • the effectiveness of DVX for the recording and distribution of amateur audio description
  • the effectiveness of automated digital tools for enhancing the presentation of amateur audio description
  • the effectiveness of using social networks and online communities for the recruitment and training of volunteer audio describers.
 
The DVX project was an incredible success, leading to a 2014 FCC Chairman's award for Inventor Joshua Miele, and the newest audio description tool, YouDescribe.
