The Description Leadership Network (DLN) is a coalition of world-class organizations involved with the practicality, policy, and technology of blindness and video accessibility. Each DLN member organization contributes unique resources and perspectives to the partnership. The VDRDC relies upon the DLN members for assistance and advice in its R&D efforts, as well as its extensive outreach and dissemination activities.
Traditional video description (also called Audio Description, Audio Annotation, or simply Description) involves overdubbing brief segments of voice-over onto the audio track of an existing video. These brief clips are intended to provide information about the visuals that are otherwise not evident from the audio track. In this way, video materials can be made accessible for blind and visually-impaired students and consumers. A number of organizations offer guidelines for describers of different types of materials, and links to those resources can be found here. In general, description should not interrupt important audio on the original track, and should be succinct, descriptive, and unobtrusive.
