Cellular operators develop high speed mobile internet and multi-function cellular phones to activate new business model based on mobile internet services. Domestic cellular operators evolve their mobile networks from cdma2000-1x and EvDo to HSDPA to activate high speed mobile internet services. They also develop mobile internet platforms such as WIPI, BREW, and J2ME on multi-function cellular phones having multimedia solutions such as camera, MP3, MPEG, 3D game engine, DMB, PAN such as bluetooth, IrDA, W-LAN, and location information using GPS. But, content providers have problems of redevelopment of the same mobile internet application on different mobile internet platforms provided by cellular operators. In this paper, we develop conversion solutions for interoperability of mobile internet applications on WIPI and BREW using an one-pass compiler. We confirm the performance the proposed conversion solutions for the API conversion rate, the converted file size, and the full conversion time using the popular mobile games which are the killer applications on WiPI and BREW.

This paper compares and analyzes the domestic OTT services to access their success factors, strategies and examine the domestic OTT leader's wavve's unique differentiation strategy. It is a comparative study of the top five market share services based on the operator and content's key success factors criteria, revenue structure, personalization, interactive media and cooperation. As a result, the common success factors were contents that reflected the characteristics of the operators, hybrid VOD, hybrid filtering, real-time participation interaction, alliances between the same and heterogeneous industries, and utilization of existing business areas. In addition, the study confirmed that it expanded the scope of the project and operated the contents efficiently by introducing one or more business strategies. wavve has been widely validated with its content, while B2C has long-term benefits and overseas use services, and B2B has a systematic use system, differentiating itself from other services. This paper can be the foundation for identifying the strengths and differences of each service on 2021, entering the domestic OTT industry, and establishing competitive strategies.

We analyze changes of consumption behavior for bundle services for the latest three years focusing on comparing the detailed service types and service providers to understand competition structure in the market. Our major findings and implications are as follows. First, the mobile telecommunication service is certainly deemed to be a major selection criteria for bundling service provider, therefore the leading company in the mobile telecommunication has become more significant market power. Second, IPTV has an important influence for slection of bundling service provider, lately in some cases, rather than broadband Internet. Third, the individual services affecting the selection of bundling service providers clearly showed differentiation among three operators as a mobile telecommunication service of SK Group, a broadband Internet of KT, and an IPTV of LGU+. In addition, the importance of individual services in securing subscribers has been increased as the preference factors to switch a service provider were synchronized with the decision of major bundling service provider. Finally, although it is difficult to find customers' lock-In due to the latest change of their intentions to switch a provider, we find it is continuously necessary to monitor customers' lock-in as there are more long-term customers with re-contracts. Our results provide the policy implications based on the change of competition structure and usage behavior in the bundle market which is not evaluated the competiton situation.

허가받은 가입자만이 유료 방송 서비스를 수신할 수 있게 하는 접근제어시스템은 유료콘텐츠를 이용한 비즈니스 모델을 실현하는 핵심 기술이 된다. 현재 접근제어시스템시장은 업계 1, 2위를 다투는 NDS와 나그라비전의 시장 점유율 합이 70%를 넘는 독점적이고도 폐쇄적인 시장 구조를 유지하고 있다. 이는 접근제어시스템이 과금과 직결되기에 콘텐츠 사업자 및 셋톱박스 제조업체가 일단 하나의 접근제어시스템을 선택하고 나면 쉽게 다른 시스템으로 바꾸지 못하기 때문이다. 이로 인해, 가입자는 방송 서비스 사업자를 바꿀 때마다 새로운 셋톱박스로 교체해야 하는 불편함을 감수해야 한다. 이런 문제를 해결하고 시장에서 다양한 접근제어시스템들이 공존하며 자유롭게 경쟁하기 위해서 다양한 기술들이 표준으로 제안되고 있다. 본 고에서는 디지털 방송을 위한 접근제어기술에서 서로 다른 접근제어시스템간의 상호 운용성을 위한 기술 동향을 알아보도록 한다.

Competition in the broadcasting market is intensifying as OTT services are spreading. And Korea is positioned as a competent international contents supply base. This can be helpful for the domestic contents production industry. However, it can result in being incorporated as a subcontractor in the global video industry. Therefore, it is necessary for Korean OTT operators to expand their market upto overseas and maintain competitiveness by linking content competitiveness to the sales expansion. This study was conducted to reduce the risk and encourage implementation through feasibility analysis of overseas business of domestic OTT operators. The North American market was selected as a region with high potential through in-depth interviews with experts and literatures review. And it was confirmed that the partnership with local platform is effective. Then, the sales and input costs were estimated, and business was evaluated using the net present value method. Totally 18 scenarios were created using multiple estimates for copyright cost, subscribers, and rate, which are highly uncertain. From the analyses, 8 scenarios were found to be acceptable. And copyright cost has the greatest impact on business success, followed by rates and subscribers.
