VOD service provides an additional revenue model for digital broadcasting companies in addition to the existing subscription fees and advertisement-based revenue models. Therefore, each digital broadcasting company develops its own VOD service and performs frequent improvement work. In this circumstance, the developer is seeking to improve the efficiency of the VOD service development. To address the needs of such developers, this study conducted a basic study to apply the feature-oriented analysis model to the development of VOD services. The feature-oriented analysis model is recognized (through a number of case studies) as an effective tool for analyzing the requirements of softwares with the functions that are interconnected organically. In this paper, we developed a feature model of VOD service and designed the primary functions of each feature and the test-cases that can test the these functions, laying the foundation for developing VOD services based on feature-oriented analysis model.

Recently for the transfer of large size video file between sites for high-definition craft editing used by broadcasting company the Public Network is used a lot. In the IP Public Network with QoS(Quality-of-Service) not guaranteed, degradation of performance has several causes. In this paper, we have analyzed the causes of low performance to transfer a large size HD video file in long distance, in order to maximize the effectiveness, the high efficiency network could be implemented enabling the highspeed of HD video file using the connection with networks between hosts through packet creation and multi-session of Parallel TCP. We survey the result of high speed transfer system and verify the efficient transfer method using Public IP Network for large HD video file transfer in broadcasting cooperation.

While the way broadcasting contents are made has changed drastically, some conflicts appear to remain unchanged. And they are about allegedly unfair practices. The whole arguments may even be deemed natural to a certain degree, considering the characteristics of the overall creative industry. But it needs to be highlighted the conflicts are being aggravated both in drama and non-drama production industries for different reasons. The drama side of the issue comes from how the project-based organizations are organized, and will be resolved if broadcasting companies do not send over their directors. On the other hand, the non-drama side's issues are about the complaints that outsourcing production companies have about the production cost. In general, due largely to the genre's relatively weak power to generate revenue, the producers do not get the upper hand when it comes to the negotiations over financial matters.

Digital convergence put a huge challenges for broadcast media in terms of integrating user generated content (UGC). Keeping this in mind, objective of the study is to explore the factors that affecting UGC's integration in Broadcast channel from developing countries' perspective. We explored how and why UGC are appearing in Bangladeshi Television news. In-depth interview was used and news editorial level staffs were selected from leading Bangladeshi television channels. Findings suggest that, state interventions in crisis events and lack of experiences to handle crisis reporting played a crucial role to incorporate UGC in television news bulletins. One of the significant findings is that, mere traditional guidelines and work policy of the media houses will not be enough to handle user generated content as well as citizen's participation in news media. Thus, we recommend to formulate a comprehensive user generated content integration policy in the context of Bangladesh.

This study is expected to provide some basic data on how to apply more economical and efficient eco-friendly factors to reduce the carbon emissions. It has been scrutinized and analyzed the environmental factors of passive eco-friendly elements along with active eco-friendly elements as more efficient factors for energy conservation based on the case of a newly constructed broadcasting building with the green building certification in Sangam-dong DMC area. The first analysis was the energy consumption trends in Korea and the necessity of energy saving. Secondly, it was examined the energy consumption in the current status of the broadcasting building. Thirdly, it was looked into the correlation between the eco-friendly design application factors applied to the broadcasting building and the energy consumption types. As a result of the analysis, the application of fan and feed pump inverter along with ventilation system of waste heat recovery ventilation system were more meaningful in accordance with the economic feasibility of broadcasting buildings rather than economical effect of passive elements such as rooftop garden, reinforcement of building insulation. Also, the application of lighting control had the economical feasibility. Therefore, when it is intended to change the green building certification energy related evaluation items of the similar broadcasting building types, it is necessary to change the direction of adding weight to the more economical active element items in the future.

Reunification is one of the most important values that the South Korea should pursue, and Korean broadcasting takes duties as a social communicator to practice the reunification ideology. In the context of multi-channel, multi platform broadcasting system, reunification should be emphasized as fundamental broadcasting principles. This study attempts to analyze the regular programs which cover North Korea and reunification in KBS and MBC from 2001 to 2010 in order to show the practices of the reunification ideology in Korean broadcasting. The results of this study show that theses programs should make efforts to find new material and develop a new program formats. In addition, there should be various genres of reunification programs in order to deliver reunification issues in more interesting ways. TV programs regarding reunification need to be designated as mandatory programs. Based on these results, this study discusses practical suggestions and policy considerations for the practice of reunification ideology in Korean Broadcasting.

Today, each broadcasting station makes the best use of CG (computer Graphics), which is the latest technology in election broadcasting, and competes to attract the eyes of viewers. This paper investigated the history of CG technology and design transitions in election ballot counting broadcasts from the perspective of CG designers. From the 1980s, when computer-based election ballot counting began, to the full-scale use of virtual studios, the image and technology produced by CG while watching the ballot-counting broadcast video of general elections, presidential elections, and local elections. We analyzed the utilization from various angles. In Korea, we started with the EDDS (Election Data Display System) developed in-house, created a database using a computer, and introduced manual animation CG every day from that time. After that, broadcasting stations focused on diverse and gorgeous CG image competition, and CG images were expanded from 2D to 3D while technology and design developed together. From 1985 to 1992, Korean broadcasting can be seen as a transitional period in which the image changes due to the emphasis on information power while utilizing digital technology.

The ecology of Korean Production Industry has been changing rapidly. Small & medium size independent production companys have been shrinking in market share while big size production companys are taking larger share than before. This study intends to show the dramatic change of the ownership in Korean production industry and the consequencies. When considering positive development of production industry, small & medium size independent production companys should play important roles but the environment of the industry is not easy for them. The implication of this study is that small & medium size independent production companys have to search for survival strategies to adapt environmental change.

지상파방송사들의 ASO(Analog Switch-Off, 아날로그 방송 종료) 이후에 유휴대역으로 남게 되는 700MHz 대역(채널당 6MHz, 698MHz~806MHz 총 108MHz)은 4세대(4G : 4Generation) 방송과 이동통신 분야, 공공서비스 등에 활용될 수 있다. 700MHz 주파수 대역에 대해서 방송업계에서는 3D UHD방송 등 4G방송(3D UHD방송)을 위해서 주파수가 필요하다고 주장하고 있으며, 통신업계에서는 늘어나는 데이터 트래픽의 해소 및 4G 이동통신을 위해 통신분야에 배정해야 한다는 주장을 펴고 있다. 이러한 상황에서 지금까지 700MHz 대역의 활용에 관한 대부분의 연구는 이동통신 중심이었다. 그래서 700MHz 대역의 공익적 활용에 관한 본고는 주파수의 주인인 시청자의 시청권 보호 및 차세대방송 서비스의 활성화를 위해서 지상파방송의 차세대서비스(4G방송)를 위한 방송용주파수 정책마련의 필요성을 제시하였다.
