    Descriptive Video Exchange (DVX)

    This innovative technology permitted wiki-style crowd-sourcing of video description in a completely new way, opening the door to amateur description provided for any video content, and distributed to anyone without modifying or redistributing the original video in any way.

    Remote Real-Time Description (RRTD)

    Remote real-time description (RRTD) is a simple technique that will allow a describer anywhere in the world to provide real-time description for a video stream being viewed by a visually-impaired student at home, in the classroom, or on the go. In RRTD, a video feed is streamed to the describer who passes the audio (and optionally the video) to the student, along with the added live description.

    Expanded Populations Research Agenda for Description (EPRAD)

    Bridge Multimedia is collaborating with the VDRDC and the DLN to develop EPRAD, a research road map to identify the critical questions that will improve our evidence-based understanding of how description may apply to the education of students with non-visual disabilities such as ADHD and autism.

    Choreographed and Orchestrated Video Annotation (COVA)

    Choreographed and Orchestrated media refers to a relatively new concept involving different aspects of a coordinated media presentation coming from different networked devices. In this case, COVA will allow video annotations such as audio descriptions to be played from a personal device such as a smartphone, while a primary video presentation is being played on a completely separate device such as a projector in a theater.
