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.

According to the IT839 strategy which was announced by the Ministry of Information and Communication(MIC) in 2004, the convergence trend of the broadcasting and the communication would be much more promoted. Thus, the methods for protecting the broadcasting contents will be indispensible elements for the successful IPTV service achievement. This paper describes the characteristics of IPTV and the related contents protection techniques. To evaluate several security issues, we suggest a security model for IPTV, and speculate the most widespread, two security technologies for IPTV such as CAS and DRM. Moreover, candidate models of IPTV protection system are suggested based on these technologies.

In this paper, we design and implementation of effective integrated broadcast contents transmission System based on single server system. Because of previous broadcast contents transmission system is consist of various individual functional equipment. And it is not easy to use and not effective to manage for broadcast contents transmission. In this paper, we evaluated and analysed of developed system in the test environment. As a result of performance test, It showed that it was well performed without any data error in the performance test, and It showed that it was well managed, controled, scheduled, processed of the integrated broadcast contents transmission environment.

This paper describes the personal video recorder-based approach to realise enhanced services for interactive programmes on digital television. So far it is very difficult that most of interactive programmes included the vast quantities of contents, whatsoever it is data-broadcasting or HD-ready, are broadcasted on digital television via the current set-top box. Furthermore it was not possible to envisage until IPTV has been appeared. Even though IPTV makes possible for streaming the interactive services via high-speed broadband, it is not easy to receive the tremendous contents with interactivity through the current set-top box in a single effort. In this paper it suggests the effective solution to resolve the download dilemma for providing the interactive services on digital television by employing the set-top box fitted with the personal video recorder.

Ubiquitous makes it possible to expand a short-distant wireless communications infra and provide various services. Especially, it is very important to develop multimedia contents service technology through ZigBee and WPAN technology. But because the data transmission rate of IEEE 802.15.4 Standard ZigBee is low, there are many barriers for multimedia contents services. In this paper, to improve ZigBee that has the limitation of transmission rate in IEEE 802.15.4 Standard, an upgraded model to 1Mbps through MAC Layer remodeling is designed. And Zigbee-based broadcasting multimedia contents services system is designed and implementation to provide the service in Ubiquitous environment.

Recently, Korea became the first country which started Terrestrial-DMB service. The DMB service is still at a very early stage throughout the world. At this stage, it is an important issue to develop DMB contents which distinguish DMB from traditional broadcasting by utilizing DMB's mobility. In this paper, we will propose outline of map service through DMB along with related services such as traffic and location information. This outline includes the map service protocol and map data structure for DMB. There is little research at the moment related to it, and this preliminary research enables map service through DMB. A map service would bring DMB a distinct advantage over traditional broadcasting. Moreover, further services based on broadcasting network and mobility would contribute to rapid growth of DMB.
