Traffic information is considered as one of the core contents of the terrestrial DMB. This paper proposes and implements the data broadcasting system, which automatically collects data and transmits the contents in order to provide traffic information promptly The proposed data broadcasting system comprises the following three subsystems: 1 he traffic information integration system for collecting and processing data in real-time, the traffic information authoring system for automatically creating and verifying the contents, and the traffic information transmission system for transmitting the created contents. We describe these subsystems in detail about their functionality, components and interoperability. The proposed data broadcasting system provides the HWS type contents as the PAD data of the terrestrial DMB audio broadcast. Finally, we describe our implementation of the data broadcasting system, and suggest further improvements that need to be made.

The environment of digital broadcast which represents as multi-channel and multimedia provides more crisis and pressure to newspapermen called as an uncrowned monarch in region of the press. The circulation of newspaper is declining dramatically and newspaper companies are turning their attention into digital broadcast in order to survive. Furthermore, besides of Chosun, Jung-Ang and Dong-A which are the three major newspapers in S. Korea, local newspaper companies are suffering from severe financial difficulties. However it could be an opportunity for digital broadcasters who undergo the lack of contents whether they are qualitative or quantitative. For the purpose of this study, it is to present a number of strategic approach in order that local newspapers outlast in the competitive digital broadcasting marketplace. Beyond the localism it intends to discuss about tapping into valuable newspaper contents as on-line journalism.

Since starting of terrestrial digital broadcasting in 2001, there has been discussion on introduction of multiple broadcasting services, one of advantages of digital broadcasting. In the mean time, task force on terrestrial multiple channel experimental broadcasting was formed with government organizations, broadcasting companies and household appliance companies in Oct. 2013, and terrestrial multiple channel experimental broadcasting was started between Jan. to April, 2014. Based on this experimental result, EBS started 2HD MMS experimental broadcasting first in Korea on Feb. 11, 2015. This study was carried out in consideration of operation of 2 HD channels in existing 6MHz bandwidth based on MPEG-2 codec with development of compression technology. A study on image quality optimization was carried out and applied to 2HD MMS experimental broadcasting through application experiment of variable bit rate and change according to 1080i and 720p scanning type.

Wire, wireless digital broadcasting has sharply expanded with the birth of high definition TV since 2010, the use of duplex contents as well as simplex contents has rapidly increased. Currently, our satellite communications system adopted DVB by European digital broadcasting standardization organization as a standard of domestic data broadcasting, the method how to use selective contents has been studied variously according to the development of IPTV. Digital broadcasting utilizes the method using Transport Stream Packet(TSP) by the way of multiplexing of information in order to send multimedia information such as video, audio and data of MPEG-2, this streams include detail information on TV guide and program as well as video and audio information. In order to understand these data broadcasting system, this study realized TS analyzer that divides transport stream (TS) by packet in Linux environment, analyzes and prints by function, it can help the understanding of TS, the enhancement of stream parsing ability.

최근 인터넷에서 많은 관심을 보이고 있는 개인 미디어(UCC;User Created, Contents, VC2;Viewer Created Contents, 이하 UCC-사용자가 직접 제작한 미디어 콘텐츠를 불특정 다수에게 제공하는 서비스) 중에 비디오/오디오 콘텐츠를 영상 콘텐츠의 기본적인 매체라 할 수 있는 TV상에서 직접 즐길 수 있다면 미디어의 대상과 그 미디어의 Entertainment적인 효과는 배가될 것이다. 디지털 케이블 방송에서 UCC와 같은 다양하고 많은 미디어 콘텐츠를 디지털 TV상에서 서비스를 하고자 한다면 현재의 OCAP(OpenCable Application Plat form)기반에서는 RVOD(Real Video on Demand)와 동일한 서비스 모델을 가져야 하는 부담과 UCC 제공을 위한 방송 플랫폼별 인터페이스가 필요할 것이다. 이러한 문제점을 Return Path를 통한 RTP(Real-time Transport Protocol;RFC1889)을 이용해서 기존의 VoD(Video on Demand)스트림의 대역에서 분리하고 별도의 VOD프로토콜을 구현함으로써 라이브 방송환경과 동일한 인프라의 지속적인 확장보다는 일반적인 네트워크 프로토콜을 이용하여 VoD서비스를 위한 인프라에 많은 영향을 받지 않는 서비스가 가능할 수 있을 것이다. 따라서 본 논문에서는 RTP를 위한 Set-Top-Box상의 다운로드 가능한 구조의 클래스 분석과 클라이언트 대응의 UCC Transcoding 및 전송을 위한 스트리밍 서버의 설계에 중점을 두고 경량화 된 VOD서비스 및 시스템을 설계함으로써 방송환경 하에 On-Demand서비스의 효율적인 확장성과 보다 많은 콘텐츠 등록 및 활용의 기회를 가져올 수 있을 것으로 기대한다.

With the start of terrestrial digital broadcast, we can view HD digital contents in TV. Also we can record, play, redistribute digital contents over the various way. Therefore the protection of Digital Contents Right became the important issue. In this paper, we implement a manager that prevents indiscriminate digital contents redistribution of the terrestrial digital broadcast contents. For protection of Digital contents Right, we use BF(Broadcast Flag) that we can control viewing or copy digital contents with.

The digital contents industry has now become the most important industry in the 21st century. Among the various digital contents industries, the animation industry has emerged as a higher value-added culture contents business with a strong possibility of growth from the field of image and character to the copyright area. Yet, the overall market structure has not been consolidated except for a few successful projects because of the sharp decline in domestic animation and the upward trend in global animation business. Due to reduced investment in producing TV animations, OSMU is an essential alternative for the animation industry. In this research, we aim to analyze the development of the domestic animation industries by studying the actual condition of OSMU for broadcasting contents.

On-going convergence between broadcasting and communication is currently bringing in lots of drastic changes to multimedia services to the home. The FTTH-based home networks will be the interface among the digital home appliances for broadcast digital contents as weil as for broadband data connection. In this paper, we discuss several design issues for home gateway architecture that effectively distributes realtime broadcasting contents (from either the headend in the access network or the satellite/terrestrial broadcasts) to heterogeneous devices in the home network.

In this paper, we present an intellectual property management and protection (IPMP) system in a broadcasting environment to provide mechanisms for copyright and contents protection that are compliant with the MPEG-2 and MPEG-4 IPMP Extension (IPMPX) specifications. The technology for processing IPMP related information was exploited, and a terminal model has been successfully designed and implemented. In addition, interoperability, which is the main objective of MPEG-2/4 IPMPX, has been addressed in detail. The experimental results show that the implemented system performs the IPMP process well, meeting the requirements of a broadcasting environment.
