Integrating Access and Collaboration for Multimedia Applications

This paper presents an architecture for a collaborative non-linear editing system whose main goal is to allow people located at distinct places to work together in the composition of MPEG2 video programmes. The system uses an applet as the front-end application, enabling access from potentially anywhere, and some features of the CORBA architecture are used to enable interaction between applets in order to provide the necessary collaboration mechanisms.

In the recent years, the Web became a great instrument for publishing and delivering online multimedia documents. Therefore, the authoring of such content became one of the most important aspect for e-learning environments as they are traditionally large producers and consumers of teaching content. In such environments the, Web may be used not only to present the information to students, but also to connect professionals (for example, professors or students) to create material for e-learning courses. This report presents the CEMT project, including the web-based environment defined for editing multimedia documents with workflow technology. The workflow technology provides a group of users scattered across the network the means of guiding the authoring process by controlling the cooperative work. This guarantees to the proposed environment a very low cost and a wider deployment, specially appropriate to the economic reality of underdevelopment countries.

Building CSCW applications is still a complex task. This paper presents a software framework based on objects for building collaborative applications mainly on top of the Web. The 10 objects of the framework are box, boxObject, enÕironment, user, role, session, broadcast, Õiew, boxObjectType and floorControl. We argue that these objects can be combined to produce a great number of collaborative applications. The main aspects in the framework and objects design are discussed. Examples of applications that were developed using the framework are also shown. q 1999 Elsevier Science B.V. All rights reserved.

We describe the CoCoMA task of the DELOS II European Network of Excellence on Digital Libraries. CoCoMA aims at the unification of the most important aspects of multimedia management and multimedia presentation, i.e., the integration of authoring, annotation and presentation design with ondemand content adaptation, ad hoc media retrieval (semantics-based and content-based), and personalized delivery and visualization of presentations. The paramount goal of the CoCoMA activity is to maximize the added value from task and data integration by the identification and exploitations of connection points and inherent workflow similarities. The paper provides a brief description of the involved research fields, suggests a architecture for integrated multimedia consumption and presentation, and discusses the most prominent connection points (e.g., the reuse of content-based metadata for content adaptation and personalization). Problems and solutions are discussed jointly and illustrated by the components of the application prototype developed for the DELOS project.

This paper explores the design space of collaborative video editing through a series of design workshops with video editors. Collaborative video editing can be supported by adding awareness features or other well-known collaborative features found in existing software and introducing new features designed specifically for video editing software. The paper identifies different design concepts that illustrate how such collaborative features can be included in non-linear video editing software and discusses the challenges of introducing such features. Some design concepts are explicitly inspired by existing collaborative tools. However, we suggest that introducing such features might not be straightforward. In other cases, alternative abstract representations of time-based media might be necessary to support collaborative video editing.

Collaborative editing (CE) has been an area of continuous research since early days of CSCW. Various CE systems have been studied in academia as research vehicles to investigate key technical issues in building advanced collaborative applications. In recent years, CE techniques have been increasingly adopted and further developed in industry for supporting real-world Internet or Cloud-based CE systems/services, such as Google Docs, Codoxware, IBM OpenCoWeb, Novell Vibe, and SubEthaEdit. This workshop aims to bring together CE academic researchers, industry developers, and endusers to discuss and exchange ideas on contemporary issues in researching, developing, and adopting CE systems. We have successfully organized this workshop annually at CSCW-related conferences. This year's workshop focuses on CE issues and techniques for supporting complex real-world documents (including but not limited to rich text, xml, spreadsheet, 2D/3D digital media, CAD, video, etc.), and evaluation of CE systems for such complex real-world documents.

Not long ago, real time collaborative editing (CE) systems were seen as a novelty to the average user, and a niche area of computer science research. Today, nothing could be further from the truth. Users are increasingly more connected and are creating more and more content online, on mobile devices, and in cloud based applications. Users are increasingly expecting collaborative editing functionalities in all of their applications. The focus of this year's workshop is: 1) to explore recent advances in the technologies that enable collaborative editing systems, 2) to evaluate the adoption of these technologies by commercial industry and the open source communities, and 3) to foster an exchange of ideas between CE researchers and end-user CE systems builders. The goal is to increase the adoption of recent technological advancements in CE research by practitioners and to have practitioners identify real-world challenges for future research.

Our main motivation for identifying the metadata present in a collaborative editing service was to offer it through electronic commerce, as we have previously done some work in the definition of electronic commerce of services. In this work we focused in controlling complex services with the help of a workflow for offering them through electronic commerce. We have also identified the metadata present in complex services and now we want to go a step further by identifying metadata present in content generated by a specific complex service, collaborative editing of multimedia documents. To help us in doing this identification, we have taken the metadata defined in Learning Object Metadata (LOM) as a starting point. In this paper, we show the selection and adaptation of this schema to our needs and also the use we make of this information in the collaborative editing service. The final result of this task should be a new schema, completely addressed to the collaborative editing service. The complex service collaborative editing of multimedia documents has been selected in this work for its relationship with electronic publishing.

Multimedia Tools and Applications, 2012

In ubiquitous computing environments, new interactive multimedia applications need to be mobile, device independent, potentially distributed across devices and to leverage existing services in the environment. Multimedia documents, when combined with scripting technologies, can represent complex interactive multimedia applications. However, they are still not appropriate for the creation of migratable, distributed applications in dynamic environments. We present a framework for interactive multimedia documents, which enables the communication of documents with a changing environment, the mobility of documents and the distribution of communicating document components in this environment. This framework uses an original approach, which describes communication processing outside of the document. It is based on: an abstraction model for dynamic network services; the definition of a binding description language that describes how to connect the network processing with the multimedia document processing; and on associated script programming interfaces. An implementation is presented and several examples, demonstrating in particular document mobility and document modularity, are discussed.
