Automatic content extraction from multimedia files is a hot topic nowadays. Moving Picture Experts Group develops MPEG-7 standard, which aims to define a unified interface for multimedia content description, including audio data. Audio description in MPEG-7 comprises features that can be useful for any content-based search of sound files. In this paper, we investigate how to optimize sound repr...

Region-based approach has become a popular research trend in the field of multimedia database retrieval. In this paper, we present the Region Frequency and Inverse Picture Frequency (RF*IPF) weighting, a measure developed to unify region-based multimedia retrieval systems with textbased information retrieval systems. The weighting measure gives the highest weight to regions that occur often in ...

The aim of this paper is to review some of the standards, connected with multimedia and their metadata. We start with MPEG family. MPEG-21 provides an open framework for multimedia delivery and consumption. MPEG7 is a multimedia content description standard. With the Internet grow several format were proposed for media scenes description. Some of them are open standards such as: VRML1, X3D2, SM...

Emerging multimedia network technologies are bringing new challenges to protocols design, due to new QoS requirements. These requirements, when combined with traditional network functions, such as routing, render the design of such protocols more complex than ever before. Resource reservation is one of the novel features brought into the picture by multimedia applications. Another is the manyto...

The rapid use of technology in lecture activities, especially the interactive multimedia since pandemic conditions and until now, has attracted researchers to comprehensively analyze patterns utilization. This study aims provide information on pattern utilization its development date. research method adopted a qualitative design, through review various studies from 2020 2023, literature search ...

Digital video compression techniques have a crucial contribution in the world of telecommunication and multimedia sector where bandwidth is a valued constraint. A large amount of multimedia data has to be stored in a limited storage space. Hence, video compression techniques mainly focus on reducing the volume of information required for picture sequences/streaming pictures without losing much ...

We are working on a method, called CEPIAH. We propose a web based system used to help teachers to design multimedia documents and to evaluate their prototypes. Our current research objectives are to create a methodology to sustain the educational hypermedia design and evaluation. A module is used to evaluate multimedia software applied in educational context. We structured a knowledge base comp...

Wireless enabled cyber physical systems and applications, highly interactive multimedia modules, and virtual organization tools and capabilities provide attractive avenues for boosting interest and improving teaching effectiveness of STEM courses in schools. In this paper we describe the Research Experience for Teachers (RET)–Hawaii program and present features of some of the developed multimed...
