Since the revised enforcement ordinance of the broadcasting legislation, Product Placement that was introduced in May, 2010 has expanded the stable income of broadcasting contents and broadcasting advertising industry, and improved the quality of the broadcasting contents and its service. However, as a result of Product Placement enforcement for the past 3 months, it reveals many problems, and is blamed for being unable to meet the intent of the law. Accordingly, Product Placement is not established properly. Thus, it is required to improve the detailed action plan for revitalization of Broadcasting Contents and Broadcasting Advertising Industry as originally intended. For example, the outsourcing production company involved in producing programs like dramas and the broadcaster have failed to reach negotiation on distributing proportion and it is keenly in need of its related study. This study is to cover the current status and the problems of introducing Product Placement, and is expected to provide the policy implications and the practical lessons. However, it displays limits that it ends in exploring and policy debate. It is henceforth expected to continue various studies of measuring the effectiveness, strategy, creative, and so forth based on discussion of introducing Product Placement.

In this paper, we firstly propose a novel cooperative transmission protocol, which utilizes the advantages of mid-notes in the route from the source to the destination. Taking benefits from balancing between the received packet from the source and acknowledge message from the destination, the mid-node between the source and the destination is firstly considered to be the broadcaster. If its signal is successfully received from the source, it leads to consider the next nodes, which has closer distance to the destination than it. If one of these nodes correctly receives the signal, it performs broadcasting the signal to the destination instead of mid-node. Otherwise, the mid-node directs attention to these nodes being near to the destination. As the result, some nodes are unnecessary to be considered and passed over time. After that, we analyze some published selection relaying schemes based on geographic information to choose the best nodes instead of the instantaneous SNR as before. Finally, simulation results are given to demonstrate the correctness of the performance analyses and show the significant improvement of the selection relaying schemes based geographic information compared to the other ones.

For the realization of future intelligent transportation systems, fine-grained lane-by-lane traffic monitoring and control functionalities are among the most important technology barriers to overcome. To satisfy the accuracy requirement for traffic monitoring, a GNSS receiver network is designed. The designed receiver network consists of three different types of entities; reference server, broadcaster, and client. For deployment flexibility, all the entities utilize the international message standard RTCM SC-104 version 3.0. For fine-grained traffic monitoring, the client is designed to utilize position-domain carrier-smoothed-code filters to provide accurate vehicle coordinates in spite of frequent addages and outages of visible satellites. An experiment result is presented to evaluate the positioning accuracy of the proposed method.

As the use of mass media in modern politics grows, its influential power is getting larger than before. Therefore, fairness of broadcasting is identified as a very important factor in the current law. In particular, whether the mass media has balanced attitude toward election issues has been a critical point, which maked the current law have separate provisons to deal with it. As for the fairness and bias, most existing studies had focused on how long the media dealt with the specific political issues, which leads to only quantitative analysis. Also, most analysis of the contents had been based on very personal judgement and evaluation of researchers rather than following the criteria which is based on scientific method. This study introduced the AHP analysis method to compare the quantitative data and qualitative data altogether, which aims to develope the indicator for weighted measures and measurement of the fairness. Research findings reveals that each broadcaster has, MBC was highly biased and KBS and SBS followed that. Compared with existing studies regarding the political fairness of the media.

This paper deals with the viewing rate trends of digital media service special reference to terrestrial real time broadcasting of IPTV. In a few years, TV viewership of young people is decreasing, the audience viewing rate of the terrestrial broadcasting which is the representative of the media decreases, and the change of the broadcasting industry is progressing. Especially after the terrestrial broadcaster 's VOD holdback was extended, the viewer' s movement on the competitive channel & mobile media was rapidly progressing. Researcher assumed that the viewing rate of the terrestrial real-time broadcasting has influenced the comprehensive channel, CJ E&M subsidiary channels. As a result, researcher verified using statistical methodological time series analysis and regression analysis. Based on these results, researcher expects media players to prepare policies for viewers' satisfaction and symbiotic growth of markets.

Government has strictly regulated the concentration of the media market because the number of broadcasters was traditionally limited and they had significant influence on public. However as the media market converges with Internet's open architecture, scarcity and pervasiveness are losing their roles in justifying media regulation. This article examines market convergence and its impact on market concentration, and criticizes the current concentration regulation. The study indicates that market performance are much governed by firm's competitive actions than market structure, and that vertical integration contributes to service innovations, and that horizontal concentration makes it difficult to measure due to its even-changing market definition. Therefore, the regulation for market concentration should shift its focus from firm's market share to broadcaster's unfair acts driving market inefficiency and hurting content diversity.

This study aims to analyse the process of digital switchover in the UK, which is regarded as one of the most successful cases in the world, and to examine efficient plans for the future digital switchover project in Korea through the UK's case. The digital switchover in the UK shows with no doubt the significance of integrated government policies, collaboration between relevant governmental organisations, and the public service broadcaster. Along with this, active and detailed Public Relations (PR) should take place, helping the citizens realise the efficiency of the phased switchover region by region and the measures to resolve the gaps between all social brackets. To sum up, the successful digital transfer is not only achieved by governmental policy and technological preparation from broadcasters, but also by voluntary citizen participation. Government officers and broadcast executives need to realise this and should focus on communicating with citizens.

In this paper, we analyzed the stereotyped and non - stereotyped data in order to analyze the drama 's ratings. The formalized data collection collected 19 items from the four areas of drama information, person information, broadcasting information, and audience rating information of each broadcasting company. Atypical data were collected from bulletin boards, pre - broadcast blogs and post - broadcast blogs operated by each broadcasting company using a crawling technique. As a result of comparing the differences according to the four areas for each broadcaster from the collected regular data, the results were similar to each other. And we derived seven related words by analyzing the correlation of occurrence frequencies from unstructured data collected from bulletin boards and blogs of each broadcasting company. The derived associations were obtained through reliability analysis.

While total sales of broadcasting business have been increasing, terrestrial broadcasters' sales are stagnant and comprehensive programming program providers(PPs)' sales are increasing. The purpose of this study is to derive implications by analyzing the relative efficiency and super-efficiency of domestic broadcasters in such an asymmetric situation. In this study, we use input and output data of three central terrestrial broadcasters and four comprehensive programming PPs from 2012 to 2019. For the analysis, Additive DEA model and Additive super-efficiency DEA model are used with the assumption of VRS condition since the broadcasting industry is characterized by economies of scale. As a result, we find out that the input excess of tangible assets is the most decisive cause of inefficiency that reduces the efficiency of central terrestrial broadcasters. On the other hand, for the comprehensive programming PPs, the input excess of tangible assets and the output shortfall of total sales are important factors of inefficiency.

In this paper, we propose a method of generating theme, background amd signal music usage monitoring information based on a blockchain, in which the music usage informations are recorded by the monitoring tool using feature-based filtering of monitoring organizations. Theme, background and signal music are music inserted into the broadcasting contents of broadcaster. Since they are recognized as created contents just like normal music, there are lyricists and composers who have the right for those music and all copyright holders of them have to receive the corresponding copyright fees, once the music was used in the broadcast. However, there are problems with inaccurate monitoring results for music usage, due to the omission of usage details and non-transparent settlement method. In order to solve these problems, If the information generation method proposed in this paper, accurate music usage history can be created, the details are stored in the blockchain without changes or omissions, and transparent settlement and distribution are possible by smart contract, avoiding the current non-transparent settlement method.
