Although the importance of video sharing and of social media is increasing from day to day, a full integration of videos into social media is not achieved yet. We have developed a system that maps the concept of hypervideo -allowing to annotate objects in a video -to social media. We define this combination as social video that simultaneously allows a large number of users to contribute to the content of a video. Users can annotate video objects by adding images, text, other videos, Web links, or even communication topics. An integrated chat system allows users to communicate with friends and to link these topics to distinct objects in the video. We analyze the technical functionality and the user acceptance of our social video system in detail. Due to the integration into the social network Facebook more than 12,000 users have already accessed our system.

This work discusses a distributed interactive video system that supports video annotation using simultaneous hyperlinking by multiple users. The users mark and annotate objects within the video with links to other media such as text, images, websites, or other videos. Annotations are visualized on the client user interface as an overlay close to the objects. Our system is intuitive to use; for example, it contains automatic object-tracking functionality that correctly positions the annotations, even when the form or location of an object changes. Thus, our first contribution discusses the adaptive object-tracking algorithm used for this repositioning. It shows improved precision and reliability in comparison to nonadaptive algorithms. A second key issue is to keep the system responsive when the number of concurrent annotators increases. Thus, we rely on the concept of eventual consistency between different network entities. While this weak form of consistency allows temporary inconsistencies, it ensures that a consistent state can be reached. Thus, the second contribution is the design and evaluation of our distributed interactive video system, which relies on the weak consistency paradigm.
