Evaluating the crisis communications campaign during the 2020–21 eruption of La Soufrière, St Vincent

Abstract During the 2020–21 eruption of La Soufrière, St Vincent, the University of the West Indies, Seismic Research Centre played a major role in supporting communication of hazard and risk information to publics and stakeholders across St Vincent. Due to COVID-19 restrictions on in-person education and outreach activities, the communications campaign was heavily reliant on social media platforms, and TV and radio broadcasts. Although the communications approach sought to be inclusive of all members of the affected communities, we consider that more vulnerable residents, such as the elderly, children, and those with low literacy levels and limited digital access were likely excluded from the communication efforts. In order to establish effectiveness of the crisis communications campaign at engaging communities and stakeholders with relevant information, and to identify areas for improvement, a large-scale evaluation campaign was conducted in St Vincent in August 2021. The results demonstrate that radio broadcasts are the most important communication tool for broad community reach, but that person-to-person information sharing was more important in the most exposed communities. Agencies such as the Red Cross and grassroots community disaster preparedness groups were instrumental in amplifying the reach of information to vulnerable members of at-risk communities and for evacuation co-ordination.

The Analysis of the Artistic Innovation of LED Lighting in Gymnasiums Based on Intelligent Lighting Control Systems

With people's attention to and participation in sports, large-scale and comprehensive gymnasiums have sprung up nationwide. Unlike previous small gymnasiums, large modern gymnasiums have more robust functions, more intelligent control, and humanization. However, some shortcomings remain, such as too centralized control and inflexible control. Therefore, intelligent control and energy saving of lighting will become the development direction of lighting systems. To ensure the normal progress of sports events and the quality of TV broadcast, the requirements of gym lighting are increasingly stringent, so the lighting control system of gyms has higher requirements accordingly. To solve these problems, this paper designs a gym intelligent control lighting system based on LED bus, which can adapt to the corresponding lighting scenes of different venues. The experimental results show that the intelligent lighting control system designed in this paper can run normally and stably, and can complete the detection of crucial working parameters. This system can automatically control the light and dark and switch off according to the indoor lighting brightness, achieving a sound energy saving effect, improving the lighting environment, and achieving the desired goal.

Transformation and diversification of Banten TV business as local television industry in the digital era

The digital era has changed all aspects of life, including the aspects of the broadcasting industry. The presence of Internet technology also presents a new system in the broadcasting industry. changes in the broadcasting system have also resulted in business diversification in the broadcasting industry. in this digital era, it has also tightened the business competition in the broadcasting industry, such as Banten TV. The formulation of the problem in this study is how to transform and diversify Banten TV's business in maintaining the broadcasting industry business. The method used in this study is a qualitative method with a case study approach by exploring the transformation and Diversification of the Banten TV Business; the paradigm used is constructivism with the theory of media ecology from Marshall McLuhan. Hasi research shows that Banten TV, as the largest local television in Banten province, transforms broadcast content by broadcasting entertainment and local wisdom, such as the local culture and religion in Banten province. With broadcast coverage using a 5000-watt transmitter, it certainly has a potential role in raising local wisdom with a very wide radiance; the transformation of Banten TV broadcast content is carried out by raising a religious superior program with the name of the Sholawat program (Solusi Tepat Per erat Umat) as a superior program in raising local wisdom in Banten which is religious and also the exploration of tourist destinations in the Banten region. In addition to transforming content, Banten TV also diversified its business by creating television program programs in collaboration with the Banten provincial government as a strategy for increasing the company's economic value

Time Synchronization and Signal Detection in Non-Orthogonal Unicast and Broadcast Networks

The next generation digital TV (DTV) broadcast, namely Advanced Television System Committee (ATSC) 3.0, relies on substantial single frequency networks (SFN), each of which requires a studio to transmitter link (STL) to transmit data from the broadcast gateway (BG), leading to significant construction costs. Therefore, the wireless in-band distribution link (IDL) technology is proposed, which uses layered-division multiplexing (LDM) to transmit the STL data via wireless links from the BG to the SFN transmitters within the same spectrum as the broadcast services. In this paper, we propose the time synchronization and signal detection algorithm for wireless IDL systems with both unicast and broadcast signals. We introduce two multiplexing schemes, N-LDM and 3-LDM, and demonstrate their superiority over traditional frequency division multiplexing (FDM). To overcome the challenge of multi-access interference and synchronization errors caused by multipath, we develop a unique word (UW) design algorithm for transmitted signals and a double threshold correlation detection algorithm (DTCDA) that outperforms traditional ones. We employ a second threshold to enhance detection performance at low signal-to-noise ratios, and utilizes successive interference cancellation (SIC) to mitigate multiple-access interference. More importantly, our approach requires no knowledge of the unicast user number or channel state information. Simulation results validate the effectiveness of the proposed scheme.

8K Ultra HD TV broadcast system: challenge, architecture and implementation

The size of the audio and video (AV) content of the 8K program is four times larger than that of 4K content, providing viewers with a more ideal audiovisual experience while placing higher demands on the capability and efficiency of document preparation and processing, signal transmission, and scheduling. However, it is difficult to meet the high robustness requirements of 8K broadcast services because the existing broadcast system architecture is limited by efficiency, cost, and other factors. In this study, an 8K Ultra-High-Definition (UHD) TV program broadcast scheme was designed. The verification results show that the scheme is high quality, highly efficient, and robust. In particular, in the research, the file format normalizing module was first placed in the broadcast area instead of the file preparation area, and the low-compression transmission scheme of the all-IP signal JPEG XS was designed in the signal transmission area for improving the efficiency of the scheme. Next, to reduce the impact on the robustness of broadcast services, the broadcast control logic of the broadcast core components is optimized. Finally, a series of 8K TV program broadcasting systems have been implemented and their performance has been verified. The results show that the system meets the efficiency and robustness requirements of a high-quality 8K AV broadcast system, and thus has a high degree of practicability.

Hybrid News (in the) Making: A Content and Corpus-Based Discourse Analysis of Political Live Blogs on the 2020 US Presidential Debates

ABSTRACT Political journalism continues to be the main source of political information in deliberative democracies. However, the advent of hybrid media systems during the last decade(s) has altered how journalists cover politics and how audiences consume relevant content. In this context, live blogging has emerged as a web-based alternative to traditional TV broadcasting. To explore whether and in which forms the trend toward hybrid media systems is empirically traceable in current journalism practice, the present study focuses on political live blogging from four popular media outlets covering the two 2020 US presidential TV debates. It applies a discourse-oriented, mixed-methods, corpus-based approach and specifically considers sourcing practices as well as the normalization of professional role conceptions and practices of objectivity. Results suggest that political live blogging establishes multi-layered and multi-authored discourse that places strong emphasis on accountability and disclosure transparency by updating and linking information, while maintaining the journalistic gatekeeping/gatewatching function. It further emerges that political live blogs are characterized by an informal tone but also by a continuation of traditional news media practices as regards objectivity, as instantiated by the salience of debate topics and political terms and by a clear delineation of information from opinion and contextualization.

Effects of Village Education and Access to Information on Mangrove Forest Areas: Studies in Indonesia

This study seeks to gather empirical evidence regarding education and access to information in affecting mangrove forests in Indonesia. The motivation for this study comes from the fact that Indonesia has experienced enormous mangrove deforestation in the last three decades. This study uses village level data in Indonesia. With a combination of geospatial data and PODES, the author uses the unbalanced panel data and Fixed Effects Model (FEM) to analyze the correlation of 9-year basic education facilities and higher education as well as national private TV broadcasts and overseas TV broadcasts on the area of mangrove forests. The author found that villages that have higher education facilities and get overseas TV broadcasts have a positive correlation with the area of mangrove forests in the village area. Higher education and broad access to information globally can certainly increase villagers’ knowledge and concern about the importance of mangrove forests. Therefore, government policies are needed to improve higher education facilities and access to global information in villages to reduce the exploitation of villagers against mangrove forests, especially for village communities located around mangrove forests.

Implementation of the analog switch off towards digital broadcast Jawa Pos

Background: It is a common fact that the rapid development of technology influenced many aspects of the world, including mass communication. Television, as the most popular and familiar broadcast media in Indonesia, has experienced several changes due to the presence of advanced technology. One of the significant transformations is the transition from analog to digital broadcasting systems. The new era of digital broadcasting could improve the performance and quality of digital television itself. Purpose: This recent study aimed to obtain an overview of the realization carried out by one of the local private broadcasting institutions in Banten, JPM TV. Methods: Using a qualitative case study along with in-depth interviews and observation as data collection techniques, this study examines JPM TV from various aspects in realizing digital TV broadcasts in Banten Province. Results: The study’s findings highlighted that JPM TV strives to realize digital broadcasting by gradually replacing equipment with tools that support digital broadcasting and elements of human resources trained and prepared with special internal and external training. JPM TV also collaborated with LPPM (Mix Broadcasting Organizing Agency), namely Mix Metro TV. The ongoing process is coordinated with the government. Obstacles faced during the migration process are the socioeconomic conditions of the people who have not been able to support the digital broadcasting process, which is characterized by the difficulty of obtaining digital broadcasting at relatively low prices; besides that, it is also necessary to increase the capacity of Human Resources (HR) so that television shows are more comfortable to watch. Implications: One of the implications is that the government must innovate to provide incentives that can stimulate the readiness of the digital broadcasting ecosystem.

Strategizing of digital transformation of an industrial enterprise (on the example of Federal State Unitary Company “Russian Television and Radio Broadcasting Network”)

Technological characteristics and the scale of terrestrial broadcasting determine the status of FSUE “Russian Television and Radio Broadcasting Network” as a systemforming enterprise regarding terrestrial broadcasting of the all-Russian mandatory public TV and radio channels. In order to implement the import substitution program it is advisable to perform a digital transformation of the company, which can be successful if the strategy chosen has goals and objectives structured and synchronized in time and resources with the potential capabilities of the management object. The author uses Professor V.L. Kvint’s methodology of strategizing to formulate conceptual propositions of the strategy of digital transformation of the Russian Television and Radio Broadcasting Network. The area and subject of strategizing are the existing in the internal and external environment key processes of the enterprise whose degree of digitalization is vital for the success of the project implementation. The author formalized the basic indicators that characterize the solution of the task of creating a highly effective system of management of a television and radio broadcasting network, which provided the opportunity to specify priority directions (programs) of digital transformation. It is pointed out that the basis of the correct movement on the trajectory from Industry 3.0+ to the state of Industry 4.0 is ensured by a properly prepared strategy in which the priorities contain a system of objectives for their implementation.

Disinformation and Verification in a Digital Society: An Analysis of Strategies and Policies Applied in the European Regional TV Broadcasters of the CIRCOM Network

The recent COVID-19 health crisis has shone a spotlight on disinformation as the circulation of false information became more and more prominent. What the World Health Organization (WHO) has defined as an ‘infodemic’ poses a great risk for democracies and for society in general. In this context, public television channels, with their regional scope, actively participate in the fight against misinformation. This research aims to identify and classify the different verification initiatives and technological tools, as well as the different strategies and codes used in fact-checking tasks by European broadcasters belonging to the CIRCOM network. The methodology undertakes an exploratory approach and employs a questionnaire that is applied to a sample of the members of the network. Managers and professionals with executive profiles were asked about the management, operation and strategies used in the verification process. In light of the results obtained, it can be concluded that the current verification processes are based on human efforts, rather than technological tools, amounting to a total dependence on content curation by the writing teams in the newsroom. Thus, it is evidenced that in most cases, there is neither a specific department for verification, nor sufficient resources, despite the fact that all those surveyed regard disinformation as a priority issue, a threat to democratic integrity and a responsibility of public service media.

Simple VHF and UHF Propagation Loss Model

Empirical propagation loss models play a crucial role in a wireless communication system with their cost-effectiveness and simplicity. In this letter, we present a mathematical characterization of the Federal Communication Commission (FCC) F(50,50) curve for the Very High Frequency (VHF) and the Ultra High Frequency (UHF) band. The proposed empirical model is based on a novel step-wise curve fitting the FCC signal strength data. The F(50,50) model is intended for the TV broadcasting system and has been employed effectively in different literary works. Following this, we proposed a simple mathematical expression applicable to a 100 km distance with antenna height ranging from 30 to 300 m. The results showed that the proposed mathematical formulation agreed well with the F(50,50) curve data. Furthermore, the model presented is straightforward and can readily be implemented in VHF and UHF signal loss calculation requiring minimal input parameters.

Comparative Study on The Business Models of the Chinese and British Football Super League

As one of the top football leagues in the world, the Premier League's business model is established according to the operation and management of modern enterprises. China's professional football league was officially launched in 1993, and its business model is still relatively low. Through a comparative study of the business models of the Chinese and British Premier League, it is found that the maturity of the Premier League's business model is inseparable from its nearly 100-year football professionalization process. The British Premier League has much autonomy in the management of the league. It is a monopoly organization with clear property rights over the league and strong independence in operation and management. At the same time, the league’s profits mainly come from high TV broadcast income and considerable advertising and sponsorship income. The entire business model of the Premier League has a side worthy of our country's learning and reference. The Chinese Football Association should minimize its intervention in the Chinese Super League, especially in commercial operations, and give full play to the market's regulatory role. At the same time, the Chinese Football Association should also imitate the management mechanism of the English Football Association, reduce administrative intervention in the Chinese Super League in terms of functions, and shift the focus of work from the overall management of the Chinese Super League to the construction of Chinese national teams and football echelons at all levels. Gradually fade out of the overall control of the Chinese Super League.

Machine Learning Techniques for Non-Terrestrial Networks

Traditionally, non-terrestrial networks (NTNs) are used for a limited set of applications, such as TV broadcasting and communication support during disaster relief. Nevertheless, due to their technological improvements and integration in the 5G 3GPP standards, NTNs have been gaining importance in the last years and will provide further applications and services. 3GPP standardization is integrating low-Earth orbit (LEO) satellites, high-altitude platform stations (HAPSs) and unmanned aerial systems (UASs) as non-terrestrial elements (NTEs) in the NTNs within the terrestrial 5G standard. Considering the NTE characteristics (e.g., traffic congestion, processing capacity, oscillation, altitude, pitch), it is difficult to dynamically set the optimal connection based also on the required service to properly steer the antenna beam or to schedule the UE. To this aim, machine learning (ML) can be helpful. In this paper, we present novel services supported by the NTNs and their architectures for the integration in the terrestrial 5G 3GPP standards. Then, ML techniques are proposed for managing NTN connectivity as well as to improve service performance.

Investigation of Point Refractivity Gradient and Geoclimatic Factor at 70 m Altitude in Yenagoa, Nigeria

The quality of services provided via Inter-Terrestrial radio communication links such as GSM networks, Wide Area Network (WAN), Radio and TV broadcasts is largely influenced by some meteorological parameters such as temperature, pressure and humidity. Proper knowledge of these parameters, specifically at microwave antenna heights (about 70m) is important in order to maintain an effective line-of-sight (LOS) link even during the worst weather conditions. The geoclimatic factor is an important quantity that must be considered in the design of terrestrial links for effective wireless communication. This work utilized satellite data from the European Center for Medium-Range Weather Forecasts (ECMWF) to compute the point refractivity gradient and geoclimatic factor for Yenagoa and its environs. The research was necessitated by the paucity of research on this subject matter for Yenegoa. The results of the research show that point refractivity gradient and geoclimatic factor in the study area vary with season. The average point refractivity gradient and geoclimatic factor at 70 m above the ground level are:136.433 N-unit/Km and 6.638633E-05 respectively. This implies that radiowaves propagating in this region at the said altitude is most likely to be super refractive in both rain and clear air atmospheric conditions. Rain or worst condition refers to the period when atmospheric components such as hydrometeor, lithometeor, aerosol have significant effects on propagated radio signals. Clear-air conditions means when maximum possible signal is received such that the most threatening atmospheric components (rain drops) have negligible effects on propagated signal. The results will be useful for radio engineers in the design and configuration of inter-terrestrial microwave links in Yenagoa and Its environs for optimum quality of service.
