After reviewing and conducting various studies, which found that blind and visually impaired people were consuming more television than ever but finding the activity problematic (often relying on sighted family and friends to describe for them), WGBH consulted more closely with Pfanstiehl and her husband, Cody, and then conducted its first tests of DVS in Boston in 1986. These tests (broadcasting to local groups of people of various ages and visual impairments) and further study were successful enough to merit a grant from the Corporation for Public Broadcasting

 to complete plans to establish the DVS organization permanently in 1988. After national testing, more feedback, more development of description technique, and additional grants, DVS became a regular feature of selected PBS programming in 1990. Later, DVS became an available feature in some films and home videos, including DVDs.

Technique

DVS describers watch a program and write a script describing visual elements which are important in understanding what is occurring at the time and the plot as a whole. For example, in the opening credit sequence of the children's series Arthur
Arthur (TV series)
Arthur is an American/Canadian animated educational television series for children, created by Cookie Jar Group and WGBH for the Public Broadcasting Service...

on PBS, the description has been performed as follows:

"Arthur is an 8-year-old aardvark. He wears round glasses with thick frames over his big eyes. He has two round ears on top of his oval-shaped head. He wears red sneakers and blue jeans, with a yellow sweater over a white shirt."


The length of descriptions and their placement by a producer into the program are largely dictated by what can fit in natural pauses in dialogue. (Other producers of description may have other priorities, such as synchronization with the timing of a described element's appearance, which differ from DVS's priority for detail.) Once recorded, placed and mixed with a copy of the original soundtrack, the DVS track is then "laid back" to the master tape on a separate audio track (for broadcast on the SAP) or to its own DVS master (for home video). For feature films, the descriptions are not mixed with the soundtrack, but kept separate as part of a DTS

. However, a federal court ruled in 2002 that the Federal Communications Commission had exceeded its jurisdiction by requiring broadcasters in the top 25 markets to carry video description. Since that time, the amount of new DVS television programming in the United States has declined, as has access to information regarding upcoming described programming, and as broadcasters like ABC and Fox have instead decided to devote their SAP channels to Spanish language
