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.
- 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.
