Abstract (sommario):

This paper introduces Neighbor Aware Adaptive Power flooding, an optimized flooding mechanism used in mobile ad hoc networks (MANETS) that employs several mechanisms (neighbor coverage, power control, neighbor awareness and local optimization) to limit the broadcast storm problem, reduce duplicate packet reception and lower power consumption in both transmission and reception. Upon receiving an optimized broadcast, a relay determines a new set of possible relays (to continue the flood) based upon local neighbor information and the previous optimized broadcast. Additionally, neighboring relays only consider the shared neighbors they are closest to. A relay may perform local optimization (to reduce power consumption and isolate broadcasts) by substituting one high power broadcast with two or more low power broadcasts, thereby introducing additional hops, We show that compared to blind flooding and multipoint relaying, NAAP in a static environment greatly reduces the problems associated with the broadcast storm problem, duplicate packet reception and power consumption.

Abstract (sommario):

The rapid development of network technology has brought profound changes to all sectors of society. The relaxation of national policies and the surge of sports demand have made the sports industry undergoing profound changes. The broadcast of sports events in the network environment has strong immediacy and interactive advantages, which not only brings new experience to the audience, but also causes frequent infringement. As the domestic and foreign regulations on the nature of sports broadcast rights are not clear, the judicial judgment of sports infringement is not uniform. This paper introduces the background of sports event broadcast under the network environment, and further explores the problems in the process of sports event broadcast by analyzing the development of its business model, and then puts forward some suggestions for sports event broadcast in China.

Abstract (sommario):

This article is a qualitative descriptive study that examines South Korean and East Africa Audio-visual production and distribution policies and regulations. Through analysing the results of in-depth interviews with audio-visual (broadcast) policymakers, content producers, and audiovisual business owners, this study found that South Korea reviewed regulations and policies that were protectionist in nature to more open and collaborative policies that were in tune with the digital broadcast environment. It recommended that to create successful broadcast industries, developing countries should review their broadcast policies and regulations to be in tandem with digital and media convergence environment as well as give audio-visual industry prominence by establishing ministries that deals with broadcast-related issues to promote locally, to produce content internationally, and also to source for collaboration between local and international producers.

Abstract (sommario):

This paper addresses the communication issue encountered by a hybrid controller when finding consensus in terms of the rendezvous target point in a broadcast and communication environment. This issue may result in a high level of computation and the utilization of agent resources when a continuous communication is required by agents to meet convergence requirements. Thus, an event-triggered system was integrated into the design of a broadcast and distributed consensus linear controller using the simultaneous perturbation stochastic algorithm (SPSA). The agent’s movement towards the rendezvous point is based on the broadcast value, whereas the next agent’s state position depends on the distributed local controller output. The communication error obtained during communication between the agent and neighbors is only added to the gradient approximation error of the SPSA if the event-triggered function is violated. As a result, in our model, the number of channel utilizations was lower and the agents’ performances were preserved. The efficiencies and effectiveness of the proposed controller have been compared with the traditional sampling broadcast time-triggered (BTT) approach. The time and iterations required by the broadcast event-triggered (BET) system were less than 40.42% and 21% on average as compared to BTT. The trajectory was not the same—the BET showed scattered movements at the initial stage, whereas BTT showed a linear movement. In terms of the number of channels, 28.91% of channels were preserved during the few hundred iterations. Consequently, a variety of hybrid controllers with event-triggered mechanisms can be proposed for other multi-agent motion coordination tasks.

Abstract (sommario):

In wireless environments, many mobile users may raise queries for accessing multiple data items, e.g., stock information or traffic condition, simultaneously. Most queries are identical. That is, many users may have an interest in some popular data items. Because data broadcast can offer unlimited users shareable information at the same time, a broadcast server is usually employed to disseminate all the data items periodically. Intuitively, popular data items should be scheduled and transmitted to users more efficiently than ordinary ones, so these users can thus save access time. To improve customer satisfaction, the author considers a broadcast program scheduling problem in such an environment and aims to minimize mobile users’ worst access time as well as their battery power consumption by generating near-optimal broadcast programs. The author provides theoretical analysis as a foundation of mapping the problem to another domain (i.e., from unit item to unit fragment) and this transformation makes the problem easy to solve. Moreover, an O(N logN) algorithm is proposed for this NP-hard problem. Finally, experimental results show that access time can be reduced by carefully scheduling broadcast programs. It suggests that other similar optimization problems can be solved similarly.

Abstract (sommario):

Despite its ubiquitous presence in mediated sports, the influence of in-stadium crowd response on media audiences has escaped inquiry. Considerable evidence from both within and beyond the context of sports suggests that a co-spectator’s behavior can generate “intra-audience effects” that enhance perceptions of and response to game events. To test this in the context of broadcast sports, an experiment was conducted whereby participants provided moment-to-moment evaluations of radio broadcasts of soccer where mediated spectator response was systematically altered. Results demonstrate mediated intra-audience effects that yielded both inflated perceptions of the exiting nature of play and increased sense of spatial immersion in the mediated environment. The effect was most pronounced when game events were not intrinsically exciting.

Abstract (sommario):

With the development of the live broadcast industry, security issues in the live broadcast process have become increasingly apparent. At present, the supervision of various live broadcast platforms is basically in a state of human supervision. Manpower supervision is mainly through user reporting and platform supervision measures. However, there are a large number of live broadcast rooms at the same time, and only relying on human supervision can no longer meet the monitoring needs of live broadcasts. Based on this situation, this study proposes a violation information recognition method of a live-broadcasting platform based on machine learning technology. By analyzing the similarities and differences between normal live broadcasts and violation live broadcasts, combined with the characteristics of violation image data, this study mainly detects human skin color and sensitive parts. A prominent feature of violation images is that they contain a large area of naked skin, and the ratio of the area of naked skin to the overall image area of the violation image will exceed the threshold. Skin color recognition plays a role in initial target positioning. The accuracy of skin color recognition is directly related to the recognition accuracy of the entire system, so skin color recognition is the most important part of violation information recognition. Although there are many effective skin color recognition technologies, the accuracy and stability of skin color recognition still need to be improved due to the influence of various external factors, such as light intensity, light source color, and physical equipment. When it is detected that the area of the skin color in the live screen exceeds the threshold, it is preliminarily determined to be a suspected violation video. In order to improve the recognition accuracy, it is necessary to detect sensitive parts of the suspected video. Naked female breasts are a very obvious feature in violation images. This study uses a chest feature extraction method to detect the chest in the image. When the recognition result is a violation image, it is determined that the live broadcast involves violation content. The machine learning algorithm is simple to implement, and the parameters are easy to adjust. The classifier training requires a short time and is suitable for live violation information recognition scenarios. The experimental results on the adopted data set show that the method used in this article can effectively detect videos with violation content. The recognition rate is as high as 85.98%, which is suitable for a real-life environment and has good practical significance.

Abstract (sommario):

This paper places broadcast major party convention ratings in the broader context of the changing media environment from 1976 until 2008 in order to explore the decline in audience for the convention. Broadcast convention ratings are contrasted with convention ratings for cable news networks, ratings for broadcast entertainment programming, and ratings for “event” programming. Relative to audiences for other kinds of programming, convention audiences remain large, suggesting that profit-making criteria may have distorted representations of the convention audience and views of whether airing the convention remains worthwhile.

The influence of rates and methods of phosphate placement on the productivity of lentil (Lens culinaris Medic.) was studied in a two-field experiment. Each experiment consisted of four levels of phosphorus (0, 17.5, 35.0 and 52.5 kg P ha-1) and two methods of placement (banding and broadcast). Lentils grown at Kufran had higher seed yield than those grown at Houfa. Seed yield, pods plant-1 and branches plant-1 increased significantly in both locations after phosphorus application compared with the control. Seed yield was significantly greater with band placement than with the broadcast method of phosphorus application at both locations.

Abstract (sommario):

Abstract Different planting methods are alternatives for early grazing and/or extend the grazing season of winter pastures. The objective was to evaluate different planting methods on forage and animal performance. In three consecutive years, ryegrass cv. ‘Marshall’ was conventionally planted (33 kg seed/ha), and no-till and broadcast planted on a bermudagrass stand on nine 1.33 ha pastures (3 replicates/treatment). Urea was split applied at a rate of 40 units of N/ha on d 40 after planting and on d 40 after grazing started. Each pasture was continually stocked with five steers (245 ± 12 kg initial BW). Grazing started when ryegrass was at least 25 cm tall and 1,600 kg DM/ha. In the conventional planted pastures, steers were moved out (to a ryegrass pasture) when ground was too soft, returning to experimental pastures when grazing conditions were appropriate. Forage production was greater (P < 0.05) for conventional and no-till (2,800 and 2,389 kg DM/ha) than for broadcast pastures (1,770 kg DM/ha). Planting method and yr affected (P < 0.03) start of grazing. Conventional and no-till planting started 51 and 49 d earlier than broadcasted. In 2 yr, rainfall delayed by 17 d the start of grazing in the conventional planted pastures. Grazing days was greater (P < 0.01) for no-till (95 d) than conventional and broadcast planting (61 and 49 d, respectively). While on experimental pastures, ADG was similar (P = 0.08) between treatments. Due to the difference in grazing days, production per ha was greater (P < 0.01) for no-till (450 kg/ha) than for broadcast and conventional (199 and 241 kg/ha, respectively). No-tilled pastures offered better grazing environment while broadcast pastures had the disadvantages of slow germination and less forage production. Greater number of grazing days on no-tilled pastures allowed for better animal performance and dilution of input costs.

Abstract (sommario):

Purpose The purpose of this paper is to empirically examine structural and psychological factors that may affect disaster evacuees’ usage of different media channels in a multichannel media environment. Design/methodology/approach The present study uses the 2016 Kumamoto Earthquake in Japan as the case study. It adopts a quantitative approach using structural equation modelling with data collected from an original questionnaire survey (n=744). Findings The results show that the evacuees’ usage of almost all media channels is positively related to the number of different types of media terminals they had. That said, those who were evacuated mandatorily tend to utilise internet-enabled media channels more. It is also found that traditional broadcast and internet-enabled media channels complement each other instead of displacing. Thus, multichannel appears to be an effective means for disseminating disaster information. However, it is also found that having access to a particular media channel does not necessarily mean that people will utilise it. Practical implications To fully utilise the multichannel media environment for disaster information dissemination, governments and media organisations also need to focus on the quality of the information being disseminated over both traditional broadcast and internet-enabled media channels. Originality/value Few studies have empirically examined factors that affect disaster evacuees’ usage of different media channels in a multichannel media environment. This study fills this gap and the findings may help governments and media organisations in utilising multiple media channels to disseminate disaster information.

Abstract (sommario):

Data dissemination scheme has been of great interest due to its scalability. In mobile environment, the advantage of such scheme is significant considering the inherent limitations of wireless environment. The application of broadcast indexing scheme in a wireless broadcast environment is necessary to help mobile clients to find the desired data instances efficiently. In this paper, we present a novel index structure called global indexing scheme for location-dependent queries. The proposed scheme is applied in a multi channel wireless environment and designed to serve queries efficiently in which the queries result depend on the mobile clients' current location. We develop a simulation model to find out the access time, tuning time and power consumption performance of global indexing scheme as compared to non-global indexing scheme. Additionally, we analyse the efficiency of valid scope used in the global index scheme as compared with an existing valid scope. It is found that global index performs substantially better than the existing indexing concept.

Abstract (sommario):

Abstract Ownership of the media was vested with the government, especially in the areas of issuance of licenses and renewal of such licenses, among others, through the National Broadcasting Commission empowered to carry out such salient responsibility. The empowerment of NBC through the enabling Decree in 1992 saw the emergence of private broadcast stations in Nigeria. But years after the deregulation of the broadcast media in Nigeria, the private broadcast stations and ownership are still bedeviled with some challenges, which If not well addressed, will leave them at cross roads; but if addressed properly, the sky would be too small to be their limit. To realize these, the study examined the challenges and prospects of private broadcast media using Africa Independent Television (AIT) and Rhythm 93.7fm as case studies. The survey method was used to expose the challenges faced by these stations and their prospects. In course of the study, the following findings, interalia, were discovered: that the private broadcast outfits are faced with challenges arising from poor facilities, government regulation and legislations, expensive equipment, welfare and debts. However, the study discovered that progress could be made if enabling environment would be created for them to strive.

Abstract (sommario):

Global production of literature and criticism about the environment has increased dramatically in the past decade, but black African writers and critics have not participated fully in this new approach. Literary green globalism, broadcast from metropolitan centers East and West, has inspired suspicion among some black African anglophone writers, while gaining acceptance among others, who with their Euro-American counterparts have begun to examine the relations of humanity and nature in sub-Saharan environments.

Abstract (sommario):

Autonomous vehicles need to have sufficient perception of the surrounding environment to produce appropriate driving behavior. The Vehicle-to-Vehicle (V2V) communication technology can exchange the speed, position, direction, and other information between autonomous vehicles to improve the sensing ability of the traditional on-board sensors. For example, V2V communication technology does not have a blind spot like a conventional on-board sensor, and V2V communication is not easily affected by weather conditions. However, it is almost impossible to make every vehicle a V2V-equipped vehicle in the real environment due to reasons such as policy and user choice. Low penetration of V2V-equipped vehicles greatly reduces the performance of the traditional V2V system. In this paper, however, we propose a novel method that can extend the awareness ability of the traditional V2V system without adding much extra investment. In the traditional V2V system, only a V2V-equipped vehicle can broadcast its own location information. However, the situation is somewhat different in our V2V system. Although non-V2V-equipped vehicles cannot broadcast their own location information, we can let V2V-equipped vehicle with radar and other sensors detect the location information of the surrounding non-V2V-equipped vehicles and then broadcast it out. Therefore, we think that a non-V2V-equipped vehicle can also broadcast its own location information. In this way, we greatly extend the awareness ability of the traditional V2V system. The proposed method is validated by real experiments and simulation experiments.

Abstract (sommario):

Real-time broadcast system of public transport crowding index belongs to the broadcast system of urban public transport environment in ITS. The remaining seats and vehicle weight of the bus can effectively reflect the current crowding of public transport. This paper proposes a real-time broadcast system about the crowding index in public transport based on the Internet of things. The system can be divided into four submodules: wireless sensor network node, Sink node, terminal analysis and evaluation system and site display platform.Operating datas in public transport collected by wireless sensor networking node are sent to terminal analysis and evaluation system by GPRS wireless communication mode. This system can help people choose the best travel route. It may be helpful for managers to make a better traffic assignment.

Abstract (sommario):

Channel 4's tradition of supporting, promoting and contributing to British cinema culture entered a new phase in 1998. Its film-making operations were consolidated into a single, semi-vertically integrated studio called FilmFour. On 1 November it launched a brand-new pay-TV channel of the same name. This channel programmed a variety of cinema, premiering world cinema films, FilmFour's own productions and independent films. It was the first digital channel in Britain affiliated to a public service broadcaster. The new channel was introduced on its opening night with a simultaneous broadcast with terrestrial Channel 4. Scheduled on this evening was a representative selection of films and programmes to entice viewers to take up the new channel, including the UK television premiere of The Usual Suspects (1995). This article presents a detailed textual analysis of this opening night simulcast. It examines how the new channel was presented to the audience, focusing particularly on interstitial material: the introductory programme, interviews with well-known faces from the British film industry, and additional material broadcast between the films. Evaluating the evening's output, the paper argues that the opening night simulcast represented both a marketing tool for the new channel and a means of extending the Channel 4 corporation's brand. This article offers a case study in how a public service broadcaster began to negotiate for itself a space in the new digital broadcasting environment by targeting a specific, discriminating audience.

Abstract (sommario):

The merging of broadcast platforms, the Internet and social media has challenged the former state-owned broadcasters of Indonesia to find new content strategies and forms suited to the networked media environment. Over the past decade, the arrival of digital technology and rapid growth of social media has broken down the previous linear model of service delivery in Indonesian broadcasting. However, national policy on this issue remains lacking. At present, the Indonesian Broadcast Law (Law No. 32 of 2002) only gives the country’s public radio an ability to use the spectrum in the analogue model. Digital migration, as well as legal protection of social media services, remains an ongoing debate among policy-makers, that will allow free market competition, in particular to opportune the interface of service providers and content producers. Drawing from semi-structured interviews, observations and regulatory reviews, this article broadly investigates the introduction of digital interfaces in the new public service broadcasters of Indonesia, with particular focus on the process through which Indonesian PSBs have embraced the digital media environment to enable the flow of information and public participation between the media entities and their publics. In this article, I present both technology and regulatory perspectives by emphasizing the dynamics of the digital media modes of public service delivery, particularly those through which analogue broadcasts and social media have sought new ways to intertwine. In detail, I will examine certain interactive services applied by Radio Republik Indonesia (RRI), the flagship of Indonesian national public radio, namely RRI-Play, RRI.co.id and RRI-Net, to manage audience participation. Since 2016, these digital platforms have mediated public access to RRI content, generated data on media users, and monitored technological performance. In inspecting these platforms, I refer firstly to the normative debate of public service broadcasters as ‘deliberative public sphere’ before segueing into the three public-service functions that are important in social network media landscape: curation, moderation and monitoring. Furthermore, this article analyses problems behind the regulatory design of Indonesian public-service media within the context of digital broadcasts in the country.

Abstract (sommario):

This paper proposes for the development of a path-loss model to improve the accuracy in predicting the signal level in office locations for the reception of FM broadcast. Identifying the factors that affect the signal level and eventually developing a model to predict the signal inside buildings will guide engineers in designing a broadcast system. A properly designed broadcast system will ensure optimum signal penetration in these listening areas. Further, the developed model can find applications in policy-making on the regulation of FM broadcast stations, both for analog and digital radio systems. Signal level measurements from three FM broadcast stations have been made inside eight office rooms in De La Salle University-Manila. With the three stations utilizing circularly polarized transmitting antennas, the measurements aim to determine the signal levels of the horizontal and vertical components of the received signal. These measured levels are used to determine the effects on the magnitude of the received signal of some factors, such as signal frequency and polarization, receiving antenna height, walls, transmitter-receiver distance, etc. Since the developed model is based on the measured signal levels in the actual office environment, its accuracy is then better than any of the existing models earlier developed.

Abstract (sommario):

The objective of this article is to look at the cultural indicators of television in the Netherlands from the perspective of feature that is essential to commercial TV - audiovisual advertisements. TV advertisements have been continuously gaining recognition as vital part of shared, cultural memory amongst audiences. It is therefore worth looking into the current practices of archiving and reuse of these ephemeral texts, including the digital environment. Once any commercial is removed from its original context of the broadcast TV flow and of its commercial layer, to be then placed in the archival setting – its meaning becomes radically altered. Consequently, the question is - what is left of a commercial and what becomes a cultural memory, often embedded deeply in collective psyche of generations of broadcast viewers, in the archival environment?

Abstract (sommario):

The Invictus Games are a parasport competition for service members and veterans with illnesses and injuries. The 2014 Games were aired by the BBC, for a total of 12 hr of coverage. This study aimed to investigate what messages were conveyed regarding parasport for veterans during the BBC’s Invictus Games broadcast. A content analysis was conducted. Five qualitative themes were identified: sport as rehabilitation, the promotion of ability over disability, the social environment, key outcomes of participation, and the importance of competition. Quantitative results indicated that 2 segment types accounted for the majority of the broadcast: sport coverage (50.57%) and athlete experiences (12.56%). Around half of the coverage focused on participants with a physical disability (51.62%). The findings demonstrate key similarities to and differences from previous explorations of parasport media coverage, with the needs of the event and athlete population potentially influencing the broadcast.
