Over the past 20 years, video production has developed to allow videos to reach out even to the visually impaired. A descriptive video narrates the visual elements of a film or television program allowing visually-challenged audiences to understand what?s being presented. This gives a television program an edge by reaching out to a wider audience. Today, virtually all television programs offer descriptive video. With the help of an experienced video production company you can turn your film into a quality descriptive video that visually-impaired people can ?watch?.
Overview
In the past, blind people had to ask their family members to describe to them what is happening being show on screen. This can be quite hard because someone needs to be there with the visually-impaired to enable them to know what they are watching. Unless the video provides good auditory description of the visual elements, visually-challenged people most likely are not capable of getting the entire idea of the presentation.
History
A radio broadcaster for a Philadelphia radio station started describing movies for listeners in the 1970s. Television sets were so expensive back then that not all people had one in their homes. It was an attempt to provide people with an audio description of the motion film.
Television broadcasting started to air with stereo audio in 1985. The new technology allowed the audio to be split up into two channels, one for the right and one for the left. A technology called Multi-channel Television Sound was also developed to provide a third channel designed for closed captioning for the hearing-impaired. This channel was called the Secondary Audio Program or SAP. SAP was not only beneficial to the hearing-impaired. It was later on decided that the channel can be used to provide a narrative description of the films as well. Thus began a new age for television broadcasting.
The possibility of providing descriptive video service (DVS) for the blind was conducted in 1986. Tests were administered to several groups of people with visual impairment. In 1988, the DVS organization was permanently established to provide video description for television programs. In 1990, DVS was actually a regular feature for some television programs. The technology continued to be used up to the present and it still offers an effective way of communicating video details to the blind without any help from other people.
