Multimedia Standards

Today there are many technologies connected with multimedia presentations. We will start with MPEG 21 that provides an open framework for multimedia delivery and consumption. These streaming instructions facilitate the fragmentation of content-related metadata, the association of media and metadata fragments with each other, and the synchronized streaming and processing of those fragments.

MPEG-7 is a multimedia content description standard. It was designed to standardize a set of Description Schemes and Descriptors; a language to specify these schemes, called the Description Definition Language and a scheme for coding the description. We will cover also MP7QF query format to uniformly query MPEG-7 enabled multimedia databases.

With the Internet grow several format were proposed for media scenes description. Some of them are open standards such as: VRML1, X3D2, SMIL3, SVG4, MPEG-4 BIFS, MPEG-4, XMT, MPEG-4, LaSER, COLLADA5, published by ISO, W3C, etc. Others are proposed by Adobe like Flash or 3ds by Autodesk. We will cover some of them.

Television has become the most important mass medium. There is also a fast growing community for videos in the web (e.g. YouTube). Serious attempts are done to give the users interactive functions. For these purpose standards such as MHEG, DAVIC, Java TV, MHP, GEM, OCAP and ACAP has been developed. Some of the will be presented together with the history and future of the interactive TV standards.

There exist a large number of standards for representing audiovisual metadata. We will cover the Material Exchange Format (MXF), an example for a container format, the Digital Picture Exchange (DPX) used for image sequences in digital cinema production, the Digital Cinema Package (DCP), used to transport digital movies and associated metadata to cinemas and others.

Multiple standards are used for describing of cultural artifacts. Most of them provide XML-scheme with basic metadata descriptors of the digitalized objects. According to the field of application different types are developed: general and specific standards for CHO; suitable for detection, search and retrieval of digital resources; for different areas – museums, libraries, archives, etc.

Web 2.0 communities have become mobile and multimedia based. Several Web 2.0 standards and tools such as Ajax, Web Map Server (WMS), Web Feature Server (WFS), Web Coverage Server (WCS), Geography Markup Language (GML), XML, RSS and Web 2.0 mash-ups will be presented.

The semantic web technologies for knowledge representation use RDF Schema - language for representing information about resources in the World Wide Web; OWL Web Ontology Language which is designed for use by applications that need to process the content of information instead of just presenting information to humans. Ontologies standard languages offer meta-concepts for the description of constraints and relationships among objects in multimedia scene will be also mention.

Trends in Developing Ubiquitous Learning Objects: Towards Merging Calm Computing with Collaborative Learning

There is much speculation about the potential of web technologies in transforming the world into a global village and its effects on learning. Despite such large number of predictions there is no widely accepted learning framework to help utilize the various informal communication and collaboration capabilities to facilitate learning. Currently, there are many web-based learning approaches that utilize variety of technologies including ubiquitous, pervasive, mobile, situated, wearable, ensemble, invisible, context-aware, ambient intelligence and attentive and intelligent user interfaces, each having their proponents. However, the central thesis in all these learning approaches is to provide comfort and awareness to learners by keeping them perpetually informed of what is happening with the ability of moving information to the centre of the learner attention when needed where such information will effortlessly disappear and move to the periphery of the learner attention when no longer such information is needed. All these approaches were inspired by Mark Weiser’s vision of calm computing which have had an enormous impact on the directions that the web-based learning field has taken. What is missing in this theme is notion of collaboration and learners engagements. This invited speech provides the required solution framework for learning based on collaboration besides keeping learners calm. The research trends leading to this framework are described also.

About Prof. Jinan Fiaidhi
Dr. Jinan Fiaidhi is a full Professor and the Graduate Coordinator with the Department of Computer Science, Lakehead University, Ontario, Canada since late 2001. She is also an Adjunct Research Professor with the University of Western Ontario. She received her graduate degrees in Computer Science from Essex University (PgD 1983) and Brunel University (PhD, 1986). During the period (1986-2001), Dr. Fiaidhi served at many academic positions (e.g. University of Technology (Asso. Prof and Chairperson), Philadelphia University (Asso. Prof), Applied Science University (Professor), Sultan Qaboos University (Asso. Prof.). Dr. Fiaidhi research is focused on mobile and ubiquitous learning utilizing the emerging technologies (e.g. Cloud Computing, Calm Computing, Mobile Learning, Personal Learning Environment, Enterprise Mashups, Semantic Web). Dr. Fiaidhi research is supported by the major research granting associations in Canada (e.g. NSERC, CFI). Moreover, Dr. Fiaidhi is a Professional Engineer of Ontario (PEng), Senior Member of IEEE, member of the British Computer Society (MBCS) and member of the Canadian Information Society (CIPS) holding the designate of ISP. Dr. Fiaidhi has intensive editorial experience (e.g. Editor of IEEE IT-Pro, Associate EiC of the Journal of Emerging Technologies in Web Intelligence).

Energy-efficient Management of Data Center Resources for Cloud Computing

Cloud computing offers utility-oriented IT services to users worldwide. Based on a pay-as-you-go model, it enables hosting of pervasive applications from consumer, scientific, and business domains. However, data centers hosting Cloud applications consume huge amounts of electrical energy, contributing to high operational costs and carbon footprints to the environment. In this talk, we define an architectural framework and principles for energy-efficient Cloud computing. Based on this architecture, we present our vision, open research challenges, and resource provisioning and allocation algorithms for energy-efficient management of Cloud computing environments.
