Bringing Videos to Social Media

Abstract

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.

A pattern-based evaluation of download and cache management algorithms for annotated interactive non-linear videos

“…Our strategies and algorithms provide only minor improvements to annotated linear videos as for example described by Cesar et al [8], Cattelan et al [7], and Kopf et al [26]. For these videos, the intra-scene scheduling described in Sect.…”

A heuristic evaluation of a mobile annotation tool

“…Its layout occupies a lot of space on the screen, which can be a disadvantage. Aiming to integrate video annotations with social media, the work of Kopt et al [4] presents a system integrated with Facebook that permits annotations on objects of the video.…”

Navigating videos by location

“…A use case for this field is the provision of navigation within videos by using computer vision techniques [4,5] or content analysis approaches [8]. Instead of only relying on the information and meta data of the video itself, additional information can be included in the retrieval process to improve existing solutions.…”
