“…These challenges were in many cases mainly tackled with the development of (proprietary) low-level stream adaptation algorithms. Only few projects are known at the moment that try to exploit the extended metadata annotation possibilities available with the new MPEG standards; examples are the ViTooKi 13 Video Tool Kit project [19,31] or the work described in [32].…”

“…Once the time has run, if this variation has been requested several (configurable) times it will be kept in the database, otherwise it will be eliminated. Streiger et al [16] present a personalized multimedia content delivery system dealing with both user preferences and terminal network capabilities using both MPEG-7 and MPEG-21. Initial user preferences are acquired by means of a form, which asks the user to prioritize his preferences for categories such as content topic, language, and source.…”

MPEG-7 is the leading standard for multimedia metadata creation, providing a vast array of description tools. Nevertheless, there exists a disparity between the content models and user models that may be created by the standard: metadata for content models is wide ranging and structured, but metadata for user models only support the specification of an extremely limited range of preferences where content metadata cannot be fully exploited. This results in a very incomplete mapping of user models to content models which we term the MPEG-7 content-user gap. We present a hanging basket model that closes the content-user gap by considering user models to be isomorphic to content models and thus enabling both models to be represented through MPEG-7 content description tools, specifically those concerned with events, objects and properties.

“…36 Most systems propose efficient algorithms to transcode videos but do not consider the semantic content of the videos. [37][38][39] Other approaches identify the semantic content in videos and emphasize important details in the adapted video. [39][40][41] Objects and special events indicate regions of interest.…”

A large number of recorded videos cannot be viewed on mobile devices (e.g., PDAs or mobile phones) due to inappropriate screen resolutions or color depths of the displays. Recently, automatic transcoding algorithms have been introduced which facilitate the playback of previously recorded videos on new devices. One major challenge of transcoding is the preservation of the semantic content of the videos. Although much work was done on the adaptation of the image resolution, color adaptation of videos has not been addressed in detail before. In this paper, we present a novel color adaptation algorithm for videos which preserves the semantics. In our approach, the color depth of a video is adapted to facilitate the playback of videos on mobile devices which support only a limited number of different colors. We analyze our adaptation approach in the experimental results, visualize adapted keyframes and illustrate, that we obtain a better quality and are able to recognize much more details with our approach.
