Advanced solutions for quality-oriented multimedia broadcasting

Multimedia content is increasingly being delivered via different types of networks to viewers in a variety of locations and contexts using a variety of devices. The ubiquitous nature of multimedia services comes at a cost, however. The successful delivery of multimedia services will require overcoming numerous technological challenges many of which have a direct effect on the quality of the multimedia experience. For example, due to dynamically changing requirements and networking conditions, the delivery of multimedia content has traditionally adopted a best effort approach. However, this approach has often led to the end-user perceived quality of multimedia-based services being negatively affected. Yet the quality of multimedia content is a vital issue for the continued acceptance and proliferation of these services. Indeed, end-users are becoming increasingly quality-aware in their expectations of multimedia experience and demand an ever-widening spectrum of rich multimedia-based services. As a consequence, there is a continuous and extensive research effort, by both industry and academia, to find solutions for improving the quality of multimedia content delivered to the users; as well, international standards bodies, such as the International Telecommunication Union (ITU), are renewing their effort on the standardization of multimedia technologies. There are very different directions in which research has attempted to find solutions in order to improve the quality of the rich media content delivered over various network types. It is in this context that this special issue on broadcast multimedia quality of the IEEE Transactions on Broadcasting illustrates some of these avenues and presents some of the most significant research results obtained by various teams of researchers from many countries. This special issue provides an example, albeit inevitably limited, of the richness and breath of the current research on multimedia broadcasting services. The research i- - ssues addressed in this special issue include, among others, factors that influence user perceived quality, encoding-related quality assessment and control, transmission and coverage-based solutions and objective quality measurements

Evaluasi Perangkat Lunak Electronic Record Management System (ERMS) ARTERI Menggunakan ISO 16175-2:2011

The aim of the study is to evaluate ERMS software of ARTERI that used the functional requirements of ISO 16175-2: 2011. The researcher chose aspects of search, retrieval, and rendering (disseminate) to evaluate its systems. The study uses a qualitative approach with a review of literature studies. Data were collected by observation and documentation. The findings show ARTERI only meets 10 of 49 functional requirements. Fullfilled functional requirement of ARTERI, includes: 1) Provide a flexible range of functions for locating, accessing, and retrieving records and/or metadata; 2) Allow all records in each level to be searchable; 3) Allow the user to set up a single search request; 4) Never allow a search function to reveal to a user any information; 5) Have integrated search facilities for all levels; 6) Allows users to save and re-use queries; 7) Allows users who are viewing or working with a record; 8) Allows record metadata to be searched; 9) Allows administrators to take a copy of records and reaction; and 10) Store in the metadata any change made. ARTERI needs to be developed, for instance, adding features in any field of content search, automatic search, boolean operators, and improving the user interface for search. Furthermore, the rendering, downloading, and printing features also need to be improved. Finally, the study is limited to certain functional requirements, standards, and applications. Future study needs to consider aspects that have not been discussed or comparisons with certain standards or application

On-Line Conversational Information Storage and Retrieval System

During the past several years the General Electric Company has been developing a Dynamic Automated Reporting Technique (DART). DART was conceived for application to Dynamic Situations such as exist in management of large programs. DART fulfills the following system requirements : 1) Capable of accepting inputs which vary in content, volume and structure. 2) Capable of accommodating inputs from several remote locations. 3) Ability to react to output demands which specify output content at the time of demand. 4) Function without computer programming charges. 5) Provide a means of self reporting status outputs for improving system effectiveness. 6) Capable of user operation. 7) Uses stylized English commands. 8) Capable of quick easy updating and revision. DART has been used and modified based on experiments in Information Storage and Retrieval for the last three (3) years. These experiments have involved four (4) different computer types, and have consisted of data bases of personnel files, test planning, ECP Change Tracking and as an aid in the evaluation of Missile Guidance and Range Safety Systems performance. As a result of these experiments, further generalized needs for the overall improvement of this User Oriented Conversational Remote Access System are being studied

According to the development status of human-computer interaction in intelligent environment, the research hotspots, problems and development trends of human-computer interaction are put forward

A sensitivity analysis of soil moisture retrieval from the t-w microwave emission model

The potential of the τ-ω model for retrieving the volumetric moisture content of bare and vegetated soil from dual polarisation passive microwave data acquired at single and multiple angles is tested. Measurement error and several additional sources of uncertainty will affect the theoretical retrieval accuracy. These include uncertainty in the soil temperature, the vegetation structure and consequently its microwave singlescattering albedo, and uncertainty in soil microwave emissivity based on its roughness. To test the effects of these uncertainties for simple homogeneous scenes, we attempt to retrieve soil moisture from a number of simulated microwave brightness temperature datasets generated using the τ-ω model. The uncertainties for each influence are estimated and applied to curves generated for typical scenarios, and an inverse model used to retrieve the soil moisture content, vegetation optical depth and soil temperature. The effect of each influence on the theoretical soil moisture retrieval limit is explored, the likelihood of each sensor configuration meeting user requirements is assessed, and the most effective means of improving moisture retrieval indicated

Designing a Dyslexia-Friendly Interaction with News Articles

This master's thesis presents a research project focused on improving the accessibility of news articles for people with dyslexia. A significant portion of online news content is text-based, which poses challenges for individuals with reading difficulties. While there are existing digital tools for text simplification and summarization, there is a lack of solutions specifically designed for dyslexic readers, and even fewer adapt to languages other than English. The project addresses this gap with the development of a prototype that generates simplified versions of Norwegian news articles. Adopting a user-centered perspective, qualitative research methods and literature research were conducted to provide a basis for the design process. The later developed prototype aims to provide a flexible model that can accommodate the different reading experiences and perspectives of dyslexic people. Its main functionality lies in visual and content-related text modifications. Together with results from corresponding user tests, the high-fidelity prototype provides detailed findings on how news articles can be made more accessible. They offer insights into the requirements and needs of news consumers with dyslexia and explore the potential of automatic text simplification in this context. The results can benefit companies, institutions, and organizations that are seeking to provide accessible news content, eliminating the need for manual simplification of every article. Moreover, the research conducted in this project can support further studies on design and digital accessibility solutions.Master's Thesis in Interaction and Media DesignMIX350MASV-MI

Improving perceptual multimedia quality with an adaptable communication protocol

Copyrights @ 2005 University Computing Centre ZagrebInnovations and developments in networking technology have been driven by technical considerations with little analysis of the benefit to the user. In this paper we argue that network parameters that define the network Quality of Service (QoS) must be driven by user-centric parameters such as user expectations and requirements for multimedia transmitted over a network. To this end a mechanism for mapping user-oriented parameters to network QoS parameters is outlined. The paper surveys existing methods for mapping user requirements to the network. An adaptable communication system is implemented to validate the mapping. The architecture adapts to varying network conditions caused by congestion so as to maintain user expectations and requirements. The paper also surveys research in the area of adaptable communications architectures and protocols. Our results show that such a user-biased approach to networking does bring tangible benefits to the user
