Television content enrichment and sharing: The ambulant annotator

This chapter reports on the Ambulant Annotator, a middleware extension for Personal Digital Recorders (PDR), in the form of a lightweight authoring tool, which allows the viewer to personalize television content and share it with others. Traditionally, social interactive television research has focused on the provision of synchronous communication mechanisms between distributed peers in the form of direct communication channels (text or audio chats) or distributed control (joint television watching experience). This chapter considers a broader approach that enhances the connectedness between users by providing video sharing capabilities. The Ambulant Annotator empowers viewer-side enrichment of multimedia content in the form of video fragmentation, fragments annotation and enrichment. Once the user has created his personalized enriched version of the video content, the Ambulant Annotator provides mechanisms to share it with his social network by using asynchronous communication technologies. The video manipulation mechanisms presented in this chapter does not modify the original video material, but are encoded as separate overlays in such a way that Digital Rights Management (DRM) restrictions on content reuse are respected.
