What is Descriptive Video? Descriptive video or DV is a narrative track for the blind and visually impaired viewers of visual media. It provides a voice-over description of a program's key visual elements with narration that is inserted during natural pauses in the dialogue. The narrator talks through the presentation, describing what is happening on the screen. Descriptive video is the counterpart to closed captioning for the deaf.
In Canada, the CRTC requires networks to provide a percentage of television programs to feature described video.
In the United States, the FCC is poised to require TV stations to provide video descriptions on prime time programming. On October 8, 2010, President Obama signed the 21st Century Communications and Video Accessibility Act. The legislation requires smart phones, television programs and other communications technologies to be accessible to people with vision or hearing loss. The signing marked one of the most significant victories for the disability community since the Americans with Disabilities Act was signed twenty years ago.

As well, the requirement of a descriptive video track is being phased-in in other countries around the world.
