“…Existing approaches have tackled the summarization of multimedia documents by defining an abstraction layer over the multimedia functionality of the targeted presentation formats. For instance, a set of relations between media elements is defined in [7] to enable an automated summarization algorithm of the presentation. Our approach does not define such an abstraction layer that often narrows multimedia functionality to a common set, but it structures the multimedia presentation into scalability layers that have progressive requirements in terms of quantity of information.…”

The summarization of a multimedia document is a challenge that requires the summarization of media elements combined into a document but also relies on an appropriate adaptation of its presentation. In this paper, we present a scalable multimedia model that structures the multimedia scene into incremental Spatial, Temporal and Interactive layers and progressively provides presentation details. Our proposal consists in summarizing such scalable multimedia documents based on three adaptation parameters: a targeted level of expertise, a preferred duration and a level of expectation for extended information. Our approach has been technically validated on PowerPoint-like documents using a generic MPEG-21-based adaptation framework.

“…In a seminal work, Allen introduced an intervalbased temporal algebra that defines a set of thirteen relations that "can be used to express any relationship that can hold between two intervals" [83]. Several works use this algebra either as basis for a formal timing model [84,85,86] or as an evaluation criteria for the expressiveness of languages or frameworks [87,88,89].…”

A Gals Approach for Pogramming Distributed Interactive Multimedia Applications

In this, work we investigate how to guarantee two properties in the development of interactive distributed multimedia applications: determinism and consistency. Determinism is a property of individual nodes in a distributed application and states that a program always produces the same output when fed with the same input. Consistency is a property of the whole system and states that all nodes should have the same view of the order of events. We evaluate the use of the synchronous language Céu in the context of multimedia programming for guaranteeing the determinism property. Regarding consistency, we evaluate the GALS (Globally Asynchronous Locally Synchronous) architecture for enforcing consistency. Traditionally, multimedia applications are developed using either a domain specific language or a general purpose language supported by specialized frameworks. Neither of the two approaches promotes the development of deterministic and consistent interactive distributed multimedia applications. Our investigation of the use of synchronous languages in the multimedia field led to the development of Céu-Media, a deterministic multimedia library for the synchronous language Céu, and Mars, a GALS middleware for interactive distributed multimedia applications. The results of this thesis indicate that using the guarantees of the synchronous language Céu it is possible to develop deterministic multimedia applications using Céu-Media. Furthermore, they also indicate that the consistency model enforced by the GALS middleware Mars guarantees that all nodes always agree upon the order of events in a distributed presentation. We validate our proposal by discussing the development of real-world distributed multimedia applications proposed by the research community using both, Céu-Media and Mars, highlighting the main advantages and also the drawbacks of using our approach.
