Abstract

Current multimedia offerings on the World Wide Web present media as an indivisible binary blob - accessing a particular section within a resource is typically not possible. In general, providing access within media is a hard problem - video and audio formats are typically compressed at variable bit-rates; video formats often require deep references to earlier parts of the file; and searching across multiple media streams (e.g. video and audio) requires careful consideration about synchronization.

The Annodex platform is a set of specifications and technologies, produced by CSIRO and released under an open-source license, that attempts to redress this deficiency for Ogg-based media. Annodex adds two basic concepts to a media resource - a textual "track" that contains time-aligned annotations and is part of the resource; and a means of addressing time points and time ranges within media in a streaming fashion.

With pervasive access within media, it becomes possible to create a range of enhanced, media-centric applications - for example, search engines that can direct users directly to the relevant section of videos; reference sites for primary multimedia sources; online video-remixing applications; community annotated video collections; etc.

This talk will provide a brief demonstration of the technology, discuss some of the problems which needed to be solved, and overview some current and proposed web applications centered around Annodex. Future research questions and engineering challenges will also be examined.
