Contemporary rapid advancements in science and technology have brought about and continue to convey change in all sectors of everyday life. Education as one of the institutions of utmost importance is directly and indirectly affected by these changes and needs to redefine its role to keep pace. Nowadays, information and communications technologies (ICTs), in which audiovisual media technologies are encompassed, are omnipresent in all educational levels and disciplines, including media studies. New approaches in traditional teaching methodologies, which demand many skills and abilities by the educators, are reformulated through utilization of audiovisual media technologies, aiming at administering enriched outcomes that support the objectives that are set, especially in the field of media studies, where audiovisual media technologies are an integral part and even inherent in many of the courses (journalism, radio, television, social media, public relations, communication). The purpose of this paper is to summarize, through a theory and bibliographic review, the various implementations of audiovisual media as the educational techniques and tools that will provide technology-enhanced learning. As this paper is an investigation of the effects of audiovisual media in technology-enhanced learning and teaching methodologies, the contribution to the discipline of media studies is straightforward.

Nowadays, audiovisual media technologies and audiovisual content (audiovisual media communications) play an important role in our physical/psychological health, education, and lifelong learning, causing the redefinition of the teaching methodology. As presented in the literature, the use of audiovisual media communications presuppose a new way of approaching effective teaching, which requires the educators on all educational levels and disciplines to display with competence many advanced skills and abilities. The aim of this research is to provide data that will contribute to the effective teaching utilizing audiovisual media communications in adult education. This research is a secondary research from two researches, which are qualitative and based on a quantitative method of analyzing. The primary data were collected through experiment method from adults (18 years and older), in Cyprus and Greece. The results confirm the current debate of using audiovisual media technologies within the educational process in technology-enhanced learning in education, both from the literature, and from the findings and results of various researches. This research is part of a larger, ongoing research that explores the multidisciplinary field that incorporates media, audiovisual content, and education (MACE), information and communications technologies (ICTs) in adult education (in Greece and Cyprus).

In this article, the quality of media studies education through effective teaching utilizing audiovisual media technologies and audiovisual content (audiovisual media communications) to budding journalists as adult learners (18 years and older) is researched, with results primarily intended for application in radio lessons at all educational levels and disciplines (including adult education). Nowadays, audiovisual media communications play an important role in the modern and visual-centric way of our life, while they require all of us to possess multiple-multimodal skills to have a successful professional practice and career, and especially those who study media studies, such as tomorrow’s new journalists. Data were collected after three interactive teachings with emphasis on educational effectiveness in technology-enhanced learning, through a specially designed written questionnaire with a qualitative and quantitative form (evaluation form), as case study experiments that applied qualitative action research with quasi-experiments. The results (a) confirmed (i) the theory of audiovisual media in education, as well as (ii) the genealogical characteristics and habits of budding journalists as highlighted in basic generational theory, something which appears to be in agreement with findings of previous studies and research; and (b) showed that (i) teaching methodology and educational techniques aimed primarily at adult learners in adult education kept the interest and attention of the budding journalists through the use of such specific educational communication tools as audiovisual media technologies, as well as (ii) sound/audio media, as audiovisual content may hold a significant part in a lecture.

Journalism is in a state of perpetual change due to the implementation of technological tools on an everyday basis. In the contemporary news distribution environment, the boundaries between media are no longer distinct, therefore media/journalism educational institutions should adapt curricula according to the needs of each type of medium. The aim of this paper is to present the incorporated technologies in the radio journalism undergraduate course of the School of Journalism and Mass Communications at the Aristotle University of Thessaloniki and evaluate their necessity according to the students themselves. After the completion of the course, which involves the use of specialized technological tools in audio recording and editing, a survey employing quantitative method based on the technology acceptance model was conducted. The results indicate that the students, despite the difficulties that were encountered due to the initial lack of knowledge on the technology applied, evaluated very highly both their satisfaction with the produced outcome and the usefulness of the procedure. In fact, the major result is that perceived usefulness is a key factor that determines the utilization of specialized technology.

A multimedia communication system includes both the communication protocols used to transport the real-time data and also the distributed computing system (DCS) within which any applications using these protocols must execute. The architecture presented attempts to integrate these communications protocols with the D C S in a smooth fashion in order to ease the writing of multimedia applications. Two issues are identified as being essential to the success of this integration: namely the synchronization of related real-time data streams, and the management of heterogeneous multimedia hardware. The synchronization problem is tackled by defining explicit synchronization properties at the presentation level and by providing control and synchronization operations within the DCS which operate in terms of these properties. The heterogeneity problems are addressed by separating the data transport semantics (protocols themselves) from the control semantics (protocol interfaces). The control semantics are implemented using a distributed, typed interface, scheme within the DCS (i.e., above the presentation layer), whilst the protocols themselves are implemented within the communication subsystem. The interface hetween the DCS and communications subsystem is referred to as the Orchestration interface and can he considered to lie in the presentation and session layers. A prototype implementation conforming to this architecture is currently under construction. I. INTRODUCTION VERY brief survey of recent work in multimedia A communication is presented. Work on the real-time transport of voice and video over digital networks [2], [13]. Some work has also been done on extending the OS1 reference model to cope with multimedia communication[ 141 Work on multiservice networks (MSN) and their associated protocols which are designed with the explicit goal of carrying multiple types of traffic, in particular voice and video, in addition to data. So-called asynchronous transmission networks (ATM)' are the prime candidates for the practical implementation of such networks.
