In this paper, we present an interactive data broadcasting system compliant with the Advanced Television Systems Committee (ATSC) standards. The proposed system provides users not only with various data broadcasting services but also remote interactive services. For various data broadcasting services, we have adopted a synchronized data injector that calculates the transmission time of synchronized data accurately and multiplexes synchronized data with the data of an MPEG-2 audio-visual program according to the calculated transmission time. To support remote interactive services, we designed and implemented a return channel server connected on a bi-directional interaction channel. Test results show that the proposed system provides both an asynchronous and synchronized data broadcasting service and remote interactive service appropriately.

본 연구는 미디어분야 산업환경에서 양방향 서비스와 기술의 시장현황을 살펴봄으로써 서비스의 활성화 방안을 위한 발전적 제안에 목적이 있다. 국내 양방향 방송 콘텐츠 서비스분석을 통해 지상파와 채널사용사업자 그리고 통신사들의 서비스 유형에 따른 플랫폼과 서비스 유형분석을 통해 양방향 프로그램의 특성인 개방성, 대화형 개인맞춤, 입체형 특성을 확인함으로써 각 특성별 지원 기술과 서비스 진행사항을 통해 향후 사업자들의 중요한 융합적 소재에 대한 가능성과 발전방안에 대해 제언하고자 하였다. 지상파방송사업자 경우 양방향으로 ARS, 웹사이트나 모바일 앱이 대부분 제공되었고, 케이블 SO와 위성방송사업자들은 데이터 영역을 활용한 양방향 서비스 운영에 다양성을 제공하는 것으로 나타났다. 따라서 국내 양방향 방송 프로그램 서비스 유형은 전체적으로 융합적 형태의 수익모델 니즈가 있어 새로운 경쟁력 있는 양방향 방송 프로그램 서비스 환경으로 전환이 필요한 것을 확인할 수 있었다.

Innovation on digital compression technology, high speed networking technology, digital broadcasting technology and distributed processing technology provides new interactive multimedia service that integrates telecommunication, broadcasting, and computer application. To meet the new trends, we focus our research direction to integrate the telecommunication services and the broadcasting services. For this purpose, we designed and implemented an interactive multimedia service platform based on the DAVIC specification. Our research results in the development of integrated interactive services and its experience will be feedback to the field trial service that will be launched from next year. In this paper, we will describe the overall architecture and system implementation results of the interactive multimedia service platform.

This letter describes a file format designed for interactive music service where users are able to recompose music based on their own preferences. The proposed design utilizes the flexible features of the ISO base media file format (ISO/IEC 14496-12, ISO-BMFF). The techniques offered in the proposed file format enable compact storage and efficient preset management, allowing users to recompose music with ease and convenience. Additionally, an implementation scheme for an interactive music player is shown along with its results.

Digital technology enhanced the improvement of technological aspects in the both broadcasting and telecommunications industries. The infrastructures of each industry converged to one, which impacts not only on technology but also on the broadcasting service. The current broadcasting service is characterized by one-way service, but it'll changed to be customized, or two-way service that reflects the interest of customers. This change requires a new standard to categorize and analyze the future broadcasting service converged and market structure, differing from the present standard based on the transmission channels. This study aims at forecasting the demand of interactive TV service as a representative broadcasting service in the near future, and analyzing the market structure of the broadcasting services. We assume that the present broadcasting and information and telecommunications services such as terrestrial, cable TV, satellite, digital TV services and high-speed broadband service have strong relationship with interactive TV service. First we use Bass diffusion method to predict the diffusion curve of the present five services. Then we analyze the relationship between the present services and interactive TV service by Delphi method. Finally we estimate the potential subscription number of interactive TV service based on the relationship among the services and diffusion parameters.

유비쿼터스 기술이 본격화됨에 따라 민간주도적 u-서비스 개발이 활발히 추진되고 있다. 본 논문에서는 복합단지 공간에서 활동하는 모든 참여자들을 위한 인터액티브(Interactive) u-서비스 모델 개발방법을 제시하고자 한다. 웹 2.0트렌드는 단지 내 서비스 제공자의 일방적인 정보 또는 컨텐츠 푸쉬(Push)뿐만 아니라 사용자의 참여에 의한 정보 창출과 공유를 전제로 하고 있다. 여기서 사용자 주도적 u-서비스는 다른 사용자뿐만 아니라 서비스 제공자에게 맞춤형 서비스를 창출하는데 매우 유용한 정보를 제공할 것이다. 이와 같은 인터액티브 u-복합단지에서는 정보 제공자가 사용자가 되고 정보 사용자가 정보 제공자가 되어 네트웍의 효과가 극대화되는 정보밀집형 공간이 될 것이다. 또한, 복합단지라는 제한된 장소적 특성을 고려해 볼 때 인터액티브 u-서비스가 제공하는 정보 또는 컨텐츠의 공유 및 활용의 효과가 매우 클 것으로 기대할 수 있을 것이다.

Purpose - This research primarily assesses interactive quality in the service encounters of Ethiopian Telecom from the customer and contact personnel perspectives. Research design, data, and methodology - After reviewing the literature on service encounters and interactive quality, two separate questionnaires and structured personal interviews were conducted to collect the opinions of 400 customers and 100 employees of Ethiopian Telecom. The researchers used convenience sampling; the responses, measured on a five-point Likert-type scale, were analyzed through chi-square tests conducted on SPSS 17.0. Results - Regarding the outcome expected by customers, encounter effectiveness is very low. Regarding accessibility and materiality, the corporation's personnel are freely accessible, relatively well-dressed, and have access to sophisticated office equipment and physical facilities. Finally, with regard to agent satisfaction, the telecom's contact employees are shown to gain little professional satisfaction from service encounters. Conclusion - The study clearly presents the areas in which interactive quality strongly affects both telecom customers and employees; this will help the corporation take corrective action. This is of utmost contemporary importance for both practitioners and researchers.

This paper Introduces an electronic auction service to be provided on Interactive TV (T-auction). This converged service is expected to much enhance the quality of the service to current online auction users through vivid visualization and live Interactive experience. Our study focuses on how the characteristics of the interactive TV-based shopping platform can affect users' attitudes towards the converged service. To develop our proposed research model, we extended the technology acceptance model and integrated it with a hedonic factor, or perceived enjoyment to reflect the dual characteristics of the converged system. We also adopted the variable of intermediary trust In the service as a critical mediating determinant for a successful commutations-mediated commerce. The research model was verified with an empirical study conducted on 970 Korean online auction users. Results show that both trust and perceived usefulness positively affect user adoption of the service. Trust had not only a direct effect on users' attitudes toward T-auction but also an indirect one by mediating the service quality, information quality, perceived enjoyment and ease of use. Meanwhile, the hedonic factor of T-auction contributes to increasing both the level of the intermediary's trust and its perceived usefulness. Users' enjoyment also was found to help form a positive attitude toward T-auction services. Theoretical and practical implications of this study for current e-auction service providers and potential t-auction service providers are also discussed.
