Digital Media Objects

Overview

Digital Media Objects include:

The accessibility issues of videos, audio and Adobe Flash objects include keyboard support, text equivalents and the automatic playing of audio tracks. Many types of media players and web browser combinations do not support keyboard access. In this case the accessible solution is to provide a link to open the media object in a separate window, where the media player is the only application in the window. Videos, audio and other meida objects need synchronized text captions or text transcripts of speech information. The automatic playing of audio tracks can interfere with screen readers, therefore any media track that include audio content should not start automatically.
