As broadcasting environments change rapidly to digital, user requirements for next-generation services that surpass the current HDTV service quality become more demanding. The next-generation of broadcasting services will change from HD to UHD and from 5.1 channel audio to more than 10 audio channels, including a height channel for a high quality realistic broadcasting service. In accordance with the estimated trends of future broadcasting services, we propose a 10.2 channel audio format for a Korean UHDTV broadcasting service. It can create almost similar spatial sound images as 22.2 channel audio with half the number of speakers. In this paper, we propose a 10.2 channel audio acquisition system for the creation of UHDTV content, and measurements and preliminary evaluation are carried out to determine whether the performance is acceptable for broadcasting.

Previous studies on solar cookers currently available in the market had indicated the need for redesigning to suit user requirements better. In order to help design engineers in developing next generation solar cookers, Gopal Naik and Girja Sharan use conjoint analysis to quantify values or utilities the users⁄ potential users associate with each important feature they desire Analysis reveals that three important features are: stainless steel vessel as against aluminium, provision of an electrical backup as against an exclusive solar device, and installation of an indicator to enable the user to judge the degree to which cooking has progressed.

This article sets out to present a new imagery for capturing the power and potential of Olympism in attempting to educate the next generation of sport consumers and decision makers. It is hoped that the new imagery can make a contribution on how to moderate and regulate the rampant commodification of sport. This new imagery begins with the need for physical educators to open their minds and instigate a critical orientation to thinking about sport and Olympic matters. It is argued that doing this might help in the creation of new possibilities and visions for Olympism and sport and allow us to confront some of the disagreeable contemporary concerns in sport that scholars have identified. The new imagery for Olympism is based on the development of a critical pedagogy that draws on the works of Apple, Freire and Kincheloe, and is re-contextualised for school physical education and sports programmes. It is concluded that decisions, behaviours and actions that are made at present actually propagate many of the policies that will be made tomorrow. It is argued that a critical pedagogy for Olympism is needed to address the many current disagreeable aspects of sport.

Abstract. With this contribution, we describe and publish two high-quality street-level datasets, captured with a portable high-performance Mobile Mapping System (MMS). The datasets will be freely available for scientific use. Both datasets, from a city centre and a forest represent area-wide street-level reality captures which can be used e.g. for establishing cloud-based frameworks for infrastructure management as well as for smart city and forestry applications. The quality of these data sets has been thoroughly evaluated and demonstrated. For example, georeferencing accuracies in the centimetre range using these datasets in combination with image-based georeferencing have been achieved. Both high-quality multi sensor system street-level datasets are suitable for evaluating and improving methods for multiple tasks related to high-precision 3D reality capture and the creation of digital twins. Potential applications range from localization and georeferencing, dense image matching and 3D reconstruction to combined methods such as simultaneous localization and mapping and structure-from-motion as well as classification and scene interpretation. Our dataset is available online at: https://www.fhnw.ch/habg/bimage-datasets

Today the convergence processes determine the most promising areas of modern science. This methodological setting in the field of journalism is implemented in a variety of multimedia forms, which has led to the creation of the fundamentally new information and communication environment and the emergence of a variety of multimedia projects. The question about the criteria and methods for creating a high-quality multimedia product remains open. The multimedia method of perception and presentation of materials require special philological preparation and mastering of the interdisciplinary technique of interpretation of the source materials, which would help to create its qualitative multimedia variation. To transfer the literary discourse into a multimedia projection, it is necessary to identify its semantic channels, contexts that can be implemented in the cross-media content using various technical means. In this regard, it is important to substantiate the basic principles of the contextual method of interpreting literary discourse. It is also proposed to highlight contexts that are present in the discourse and are actualized by the perceiving recipient including historical, biographical, literary, linguistic, philosophical, mythological, literary critical, as well as those of various types of art - painting, music, etc., and the scientific context. The structure-forming principle that allows comprehending these contexts as an integral system is the process of dialogic interaction of their intra- and extra-textual existence. The nature of the functioning of this context system is based on the implementation of the following factors: 1) the degree to which authorial/reader determinism manifests itself in the process of implementation of a specific context; 2) the degree of awareness/unconsciousness of the context embodiment in the work; 3) the degree of relative stiffness/probability of the context functioning; and 4) the degree of certainty/uncertainty of the implementation of the external context in the literary discourse. Considering an example of the story by Sholokhov, “The Fate of Man”, it is considered as the development of the context system in the form of a substantive basis for the further transfer of this text into a multimedia projection. It is revealed that the literary discourse is born at the junction of information and communication approaches to the text. The disclosure of the multimedia nature of literary discourse helps to restore the very process of its functioning and its dialogical nature. The contextual methodology for the interpretation of literary discourse also allows determining the dialogue channels - the context system that are the basis for the creation of high-quality multimedia content in the future. Since the multimedia method of material perception and presentation requires special preparation, it is advisable to develop the skills of multimedia thinking using the example of classical literature, based on the principles of contextual methodology. A philological literacy can also play an important role in the process of training future journalists.
