Video Enrichment

The process of augmenting video content with additional elements such as captions, audio descriptions, images, audio cues, hyperlinks, or tactile outputs to make it more accessible or informative for different audiences. Unlike traditional approaches where added elements are fixed in the video, annotation-based video enrichment separates the descriptive content from its rendering, allowing different presentation models to be applied depending on the viewer's disability and preferences. This approach enables personalisation of accessibility features and supports collaborative production of accessible video content.
