Digital cinema is an important contents provider and powerful contents as itself in the paradigm of media convergence. Digital cinema extend its screening platforms to the public television, CATV, internet and mobile channels beyond a theater. This study derives peculiar features of digital cinema that first screening on these platforms with case study. Furthermore, this study investigates features of digital cinema according to the multiplicity of platforms and a method of the utilization of digital cinema in the rapidly changing situation.

As the number of channels and programs are increasing dramatically, a viewer seriously needs to book a program at the very time of watching its promotion program by "only one time" pressing remote controller's button. The program reserving system requiring to search a program via EPG is usually hard to operate and some researches that allow a viewer to book a program via its promotion program require additional heavy facilities such as image processing or ultra-frequency recognizing systems. In this paper, a new program reservation system is introduced. the system allows a viewer to book a program via its promotion program. The system is conformable to MHP (which is the data service standard most widely adopted in the world) so that the broadcasting stations need no additional equipments to implement it as long as they follow the MHP standard.

본 논문은 디지털 케이블전송망인 HFC(Hybrid Fiber and Coaxial)망 기반하에서 6MHz 다수의 방송채널결합 기술을 이용하여, 대용량 3D 및 8K-UHD 콘텐츠 전송을 위한 방송망 채널결합형 200Mbps 급 1024-QAM 송수신시스템 개발에 대하여 기술한다. H.264 비디오 부호화기를 사용하여 8K-UHDTV 및 3D/UHD 융합형 서비스를 시청자에게 제공하기 위해서는 약 120~160Mbps 의 대용량 데이터 전송률이 확보되어야 한다. 이와같이 대용량 3D/8K-UHDTV 콘텐츠를 전송하기 위해서는 상대적으로 채널환경이 우수한 HFC 디지털 케이블망을 이용한 대용량 실감미디어 콘텐츠 전송기법에 대한 연구가 주목 받고 있다. 본 논문에서는 FPGA 를 이용하여 HFC 망 기반에서 기존 OpenCalbe/DOCSIS 3.0 256-QAM 대비 약 30% 전송효율이 개선된 3D/8K-UHDTV 대용량 실감미디어 콘텐츠 전송을 위한 방송망 채널결합형 1024-QAM 송수신기 구현 및 개발에 관한 내용을 기술한다.

In this paper, storing and removing method of broadcasting content is proposed for personalized consumption. The main objective of this paper is to keep personalized information, such as additional contents, user creation data, usage history, with broadcasting content, and user can consume broadcasting content to accommodate individual preference. Consequently, proposed file format in this paper is based on MPEG-4 and MPEG-21 file format because they can access and extract data within file format easily and can keep spatiotemporal relation between data. In addition, TV-Anytime metadata is used for program description metadata. Finally, proposed method is verified with file format player and useful application scenarios.

디지털 기술이 발전하고 네트워크가 고도화되면서 방송과 통신, 그리고 미디어의 경계가 허물어지는 '디지털 융합'이 빠르게 진행되고 있다. IPTV 서비스가 출시 2년 만에 가입자가 3백만 명을 넘어설 것으로 예상되고, 디지털방송이 도입된 지 10년도 지나지 않았는데 벌써 디지털 3D 방송으로 진화하고 있다. 통신과 인터넷 분야 또한 급격한 변화의 바람이 불고 있다. 혜성처럼 나타난 스마트폰은 기존 휴대폰을 새로운 흐름에 뒤처지는 유물로 전락시키고 있으며, 앱스토어, 태블릿PC, 스마트TV 등 하루가 다르게 새로운 방송통신 서비스와 콘텐츠들이 등장하고 있다. 본 고에서는 이러한 방송통신 시장의 최근 변화의 흐름을 살펴보고, 이러한 상황에서 우리나라가 새로운 방송통신 기술과 서비스를 선도해 나가기 위해 집중해야 할 주요 과제와 정책방향, 그리고 이를 대비하는 우리 모두의 바람직한 대응방안을 살펴본다.

Digital Content Marketplace based on Interactive Media is defmed as the marketplace for content service between contents supplier and consumer through iDTV environment. This Marketplace is increasing interest to u-Life service with Digital Environment. To Interactive Media, it can contribute to enhance its effectiveness by developing various contents and service model in the initial phase of broadcasting-communication convergence. This study designed metadata using Digital Content marketplace based on Interactive Media. Specially the matadata designing include recommendation-tag for supply supplementary content. It can support self-directed action. Through basic metadata with weight value, it is designed to support supplementary content customer to want on the marketplace. Recommendation-System can be built by many method and to recommend the service content including explicit properties using collaborative filtering method can solve limitations in existing content recommendation.

In this paper, we implemented a terrestrial/cable PSIP converting system, so-called a PSIP converter, which is converting a terrestrial PSIP into a cable PSIP for a data broadcasting service in the interoperable network of terrestrial and cable, and define an interface between the PSIP converter and the OOB SI generator by using PMCP messages compliant to ATSC T3/Sl. The exiting PSIP converter just converts a terrestrial PSIP into a cable PSIP compliant to ATSC and OCAP standard and transmits by a MPEG-2 TS format. That is to say, it is not for the digital data broadcasting but for the digital broadcasting. In addition, the PSIP converter can support various types of PSIP information to the OOB SI generator by using PMCP messages defined by a hierarchical structure as per each channel, audio/video event, data event and so on.

Since the first interactive broadcasting of Skylife had been launched in S. Korean it has passed over 4 years. Subsequently the new digital broadcasting platforms, such as DMB, Mobile-TV, IPTV and so forth, are appearing between the keen rivalries. At the centre of diagram for new digital platforms there is positioned the interactivity. In order to cope with the limitation of contents on television, even Korean terrestrials have resolutely carried out interactive broadcasting as of 8th of June, 2006. Although the flamed competition of digital environment there are lacking in the public understanding and interests for interactive programmes on digital television. We can be analysed that it is difficult to acquire the viewer's satisfaction for guessability in spite of our governmental efforts. Here it presents the problematic results obtained by analysing both quantitative and qualitative data from the usability test for the current interactive programme in centre of the viewer.
