EDV:  Embedded Described Video

Embedded Described Video (EDV) is the next generation of Described Video (DV)

EDV is an experimental method of creating described video, whereby the identification of key visual elements are incorporated into the original production of the program, such that traditional DV is not required.

In essence, the program is produced from the onset in consultation and collaboration with an experienced describer in order for blind and visually impaired audiences to understand and enjoy it without the addition of traditional DV.


The purpose of EDV is to achieve a fully inclusive television viewing experience for both the sighted and non-sighted viewers simultaneously. It was initially created specifically for AMI-tv's audience, though EDV principles can be implemented among mainstream media productions.
