Descriptions, or descriptive video, take something visual and communicate it to audiences who may have challenges consuming it. This is achieved by using audio. We often associate this type of accommodation only with regard to television, but it can be valuable in many other mediums like live theatre, museums, art galleries and travel tours.
When referring to descriptions in media there are several forms to consider.
Described Video (DV) utilizes a secondary audio track synchronized with media to provide aural representation of visual narrative. Live Described Video (DV) injects descriptions of important visual elements, in real-time, during live events. Integrated Described Video (IDV) is a seamless form of description added throughout media production process.
