“…The work more recently undertaken by a number of research groups thus addresses the use of ontologies to obtain high-level semantic descriptions of the context of usage [14]- [23]. Although some combine standards with ontologies [17], [23], a great part of the published work relies on proprietary models to acquire and represent context.…”

“…Although some combine standards with ontologies [17], [23], a great part of the published work relies on proprietary models to acquire and represent context. Moreover, they usually concentrate on a limited number of adaptations and most often upon Web content only or entertainment video and try to explore context to improve usability aspects.…”

Abstract.A major challenge when accessing protected multimedia content in heterogeneous usage environments is the ability to provide acceptable levels of quality of experience to all involving users. Additionally, different levels of protection should be possible to be addressed when manipulating the content towards the quality of experience maximization. This paper describes the use of a context-aware and Digital Rights Management (DRM)-enabled content adaptation platform towards meeting these challenges. The platform was conceived to deliver advanced content adaptation within different application scenarios, among which Virtual Collaboration (VC) was central. Descriptions of use cases implemented by the platform in heterogeneous VC environments are provided. Conducted experiments have highlighted the benefits to users when compared to an operation without the platform. Results of different adaptations suitable to sensed context conditions are also provided and analyzed. A brief description of the platform functionality is included together with pointers to additional information.

“…Conversely, CAIN-21 is not restricted to particular media types. To this end, CAIN-21 supports the integration of third-party pluggable and reusable multimedia conversion modules referred to as Component Adaptation Tools (CATs) [10]. A CAT is characterized by the set of parameters describing the media to be adapted and it explicitly specifies the set of conversions that it can perform.…”

“…Multimedia properties refer to all the elements of the multimedia system, including the media resource, the usage environment, and the adaptation capabilities. To access these properties, CAIN-21 implements a highly efficient addressing mechanism by means of XPath [13] expressions [10]. Section 3 describes this mechanism and Sect.…”

Bounded non-deterministic planning for multimedia adaptation

This paper proposes a novel combination of artificial intelligence planning and other techniques for improving decision-making in the context of multi-step multimedia content adaptation. In particular, it describes a method that allows decision-making (selecting the adaptation to perform) in situations where third-party pluggable multimedia conversion modules are involved and the multimedia adaptation planner does not know their exact adaptation capabilities. In this approach, the multimedia adaptation planner module is only responsible for a part of the required decisions; the pluggable modules make additional decisions based on different criteria. We demonstrate that partial decision-making is not only attainable, but also introduces advantages with respect to a system in which these conversion modules are not capable of providing additional decisions. This means that transferring decisions from the multi-step multimedia adaptation planner to the pluggable conversion modules increases the flexibility of the adaptation. Moreover, by allowing conversion modules to be only partially described, the range of problems that these modules can address increases, while significantly decreasing both the description length of the adaptation capabilities and the planning decision time. Finally, we specify the conditions under which knowing the partial adaptation capabilities of a set of conversion modules will be enough to compute a proper adaptation plan.
