Using video embedded markings for supporting content sensitive interaction in multiple contexts

Despite the numerous advances provided by Digital TV and Connected TV platforms, they have not provided significant gains to the television viewing experience. In the Connected TV platform, for instance, one relevant limitation is that the audiovisual content normally does not converse with the resources of these environments. In this work we propose a complementary approach to promote content-sensitive interactivity. This approach uses markup on video to promote content-sensitive interactivity based on self-contained hypermedia anchors. The anchors are self-contained metadata inserted synchronously with the narrative and contain necessary information to allow that a specific agent can lead the users to different contexts according to their interaction with the content. Our experiments show that is possible to create rich interactive narratives even with a limited set of anchor's classes, including support for pull, push and distributed modes.
