Wireless CATV is a type of CATV that offers its subscribers a mix of microwave channel by transmitting the programming over MMDS frequency. The benefit of wireless CATV can be made available in areas of scattered population and other areas where it is too expensive to build a traditional cable station. Also, due to the lower cast of building a wireless cable station, saving can be passed on to the subscribes. Therefore, in this paper 28[GHz] band bidirectional analog wireless system was proposed. When fully implemented, wireless CATV may have as many as 33 channels of broadcast. Further, if digital wireless CATV is used 150 to 300 channels may become available.

Covid-19 로 인한 마스크 착용이 청각장애인들의 소통을 더 어렵게 하는 바, 제 3 자의 도움 없이 쌍방향 소통을 가능하게 하는 서비스의 필요성이 커지고 있다. 이에 본 논문은 소통의 어려움을 겪는 청각장애인과 비청각장애인을 위한 쌍방향 소통 서비스에 대한 연구와 개발 과정, 기대 효과를 담는다. 서비스는 GRU-CNN 하이브리드 아키텍처를 사용하여 데이터셋을 영상 공간 정보와 시간 정보를 포함한 프레임으로 분할하는 영상 분류 기법과 같은 딥 러닝 알고리즘을 통해 수어 영상을 분류한다. 해당 연구는 "눈속말" 모바일 어플리케이션으로 제작 중이며 음성을 인식하여 수어영상과 텍스트로 번역결과를 제공하는 청각장애인 버전과 카메라를 통해 들어온 수어 영상을 텍스트로 변환하여 음성과 함께 제공하는 비청각장애인 버전 두 가지로 나누어 구현한다. 청각장애인과 비장애인의 쌍방향 소통을 위한 서비스는 청각장애인이 사회로 나아가기 위한 가장 기본적인 관문으로서의 역할을 할 것이며 사회 참여를 돕고 소통이라는 장벽을 넘어서는 발돋움이 될 것이라 예측된다.

Cross platform game has brought about the expansion of game market, which results in technology innovation overcoming the limit of game consumption. The new model integrates both off and online game services. Gamers can now enjoy game service regardless of age, time, and space. If the technology evolution model of digital contents like cross-platform game engine can provide contents for several platform at the same time, the interactive service can be utilized into maximum level. It is also necessary to allocate, switch data as well as to innovate the transmission technology of data according to each platform. Providing the same contents for several platform as many as possible can be the most suitable strategy to enhance the efficiency and profits. However if the interactive service can be accomplished completely, the development of data switching technology and distribution should be made. To be a leader in the next digital contents market, one should develop the network engine technology which can embody the optimization of consumption in the interactive network service.

This study attempts to investigate the personalized schemes of interface for the interactive TV sonics enhancing the satisfaction of users from the standpoints of the user and to suggest designing guidelines. In the preface, firstly, the purpose as well as structure of the study were described, the characteristics of the interactive TV and the personalization were defined. Also, it was attempted to understand the development directions of the basic media for services. In addition, the data and elements that became the ground for this study were arranged, including the elements for designing interface, the appraisal method of usability to evaluate the requirements of users, etc. Then, the interfaces of "SkyTouch", an interactive TV sonics by Skylife having the number of users reaching one million at the moment, that is the representative runner in the interactive TV, were analyzed. Then the needs central to the navigation structure and layout for the convenience of users through the evaluation of usability were examined and arranged. In addition, the designing directions of personalized interfaces were studied in the interactive TV by analyzing the web portal sites which were being carried out prior to the personalized services. Based on the data investigated and analyzed previously, the guidelines for the interface design for the personalization of the interactive TV were suggested by classifying the navigation structure and layout, and the personalized interface design was proposed according to the suggested guidelines by applying them directly to "SkyTouch" that is currently carrying out the interactive sonics although it provides limited services in an independent style.

Digital TV broadcasting technology is recognized as a very encouraging technological development by koreans because of high-definition, multi-channel and interactive services which would broaden the viewers choice and promote people's prosperity. The technological development of digital TV service is a drastic change for people's convenience and would be a major media of‘e-government’in Korea. Digital TV Program UI will affect to people's esthetic sense and information efficiency. The information search pattern in TV is different from it of computer which has lead interactive media so far This research verifies the reasonable information display method through the usability test based on former related researches. For the case study, Interactive EPG design of SkyLife is selected and reviewed. This research includes the design development of interactive EPG of DVB-MHP.

방송의 패러다임의 변화에 따라 신호방식이 아날로그에서 디지털화, 소수 지상파 방송에서 다채널 방송, 단방향에서 쌍방향 등 디지털 위성방송이 사회적 이슈가 되어 가고 있다. 이에 따라 유료방송인 디지털위성방송에 대한 이해와 컨포넌트 시스템을 정의해 보고 이에 필요한 기술과 향후 가능한 디지털 위성방송 서비스 및 비즈니스를 제시 하고자 한다.

쌍방향 TV시대를 맞아 TV를 활용한 교육 서비스가 기존 e-Learning의 한계점을 극복 할 수 있는 대안으로 혹은 또 다른 하나의 서비스로 논의되기 시작하는 단계이다. 이에 본 연구에서는 e-Learning에 대한 정의와 T-Learning에 대한 정의를 바탕으로 상호관계를 규정하고 쌍방향 TV기반의 T-Learning에서 접근 가능한 교육 유형을 고찰하였다. 또한, 인터넷 기반 학습 환경에서 기존의 산발적으로 혹은 부분적으로 이루어진 e-Learning 도입 혹은 운영 방법론에 대한 연구와 관련 변인들을 고찰하였다. 이를 바탕으로 체계적이고 통합적인 e-Learning 도입 및 운영 방법론 모델을 제시하였으며 더 나아가 TV기반 학습 환경에서의 성공적으로 T-Learning 도입 및 운영을 위한 변인 요소를 도출하기 위한 모형을 연구 제시 하였다.
