As digital broadcasting process and information compressing technologies developed, digital technologies have been used extensively in many visual media such as movies and TV programs, and it is required to develop a new process for 3 dimensional digital programs. The study attempts to develop a new digital video-producing process through pre-simulation using a digital storytelling method, in order to increase the quality of broadcasting, reducing the producing time and improve efficiency. This system, supposed to be used to produce actual broadcasting, includes all tools needed for broadcasting in the program, so users can select an appropriate set among the pre-made library, which saves time for making sets. Also, it offers a storyboard making function by perfectly representing the functions of a virtual camera, and enables users to make the better storyboard, checking the real time movies. In addition, it recognizes objects though avatars, organizes the appropriate set for these avatars to act, and embodies a variety of avatar movements through which it reaffirms the camera's position and organization, minimizing errors and saving time and budget.

In order to go digital broadcasting in Korea, it is conducted various policies in the country which be expanded network, be increased digital broadcasting hours. And broadcasting stations in the country close down analog broadcasting until 2012. Moreover IPTV is a method of delivering broadcast television and on-demand, rich media content that uses an IP(Internet protocol network) as the medium. And an IP is regarded as a very favorable approach for the future "Medium for Digital TV". However It is not easy to replace the entire digital infrastructure. And there are some problems in the digital infrastructure for Digital TV(i.e. channel zapping delay). Moreover user require service. IPMG is to solve these problems. IPMG is digital converter that allows receive and transmit signal by using many kinds of medium for Digital TV. Moreover IPMG provides users a Network PVR service. In this paper we developing, manufacturing IPMG and analyze its performance.

In the 21s1 century, it may be possible to offer comprehensive service by integrating all communication media under the development of digital technology without the classification of broadcasting and communication. In addition, it will be begun to perform HDTV broadcasting by focusing on the Metropolitan area in 2001yr and will permit over 100 channels for satellite communication, thus multi-channel TV broadcasting age has come in Korea. Therefore, this study is to identify the future environment of TV broadcasting and service area in ISDB age and to present new interactive type publication satellite TV transmission system, which provides customizing type digital screen book publication, by analyzing satellite broadcasting technology to create Korean cultural area around the Korean peninsula.

The dynamic range of the loudness after digitalization of television broadcasting is enlarged, and the loudness difference between the broadcast channel and between the programs within the same channel is expanded. This was subjected to interfere with the television viewer's comfort. In order to improve these problems international standards for the loudness normalization was established in ITU, Europe, USA and Japan. This regulation was introduced to Korea also as technical regulation, and this will apply the broadcast service in June 2016. In this paper, ahead of the introduction of digital television technology based on loudness measurement for the major television channel and to present the results of the comparison of technical standard.

In this paper, we developed digital TV commerce system using mobile device for multimedia service. This system combines TV and mobile device, and enables a TV viewer to purchase and download the multimedia contents such as songs and video programs onto the mobile devices instantly when the viewer watches the contents. Our system is different from the conventional TV commerce system in the sense that it combines digital TV and mobile device for better service, and the contents such as songs, videos and games are downloaded directly to the devices. Furthermore, our system's data flow is designed for utilizing cheaper network to save costs. We implemented this new service system, and in this paper, we describe the service in detail, comparing with conventional TV commerce system, and we present the architecture and preliminary implementation of the proposed system.

The advertisement market is an industry that is heavily influenced by media changes. As the digital broadcasting has settled, TV, a typical advertisement medium, has evolved from a passive content consuming medium into a platform for operating various data services as well as broadcasting programs. These changes mean that viewers are able to actively consume TV contents including advertisement, so the broadcasting industry needs to consider about the growth strategies that link the advertisement market with data services. This study designed a digital broadcasting data service that provides supplementary information of ID advertisement with short exposure time (less than 10 seconds) and insufficient space (less than 1/4 of TV screen). Specifically, we designed the user scenario and user interface of the data service, defined representative types of ID advertisement and the supplementary information for each type, developed a method, based on the international digital broadcasting standard DVB, for providing the supplementary information to the data service.

In Korea, transition to digital TV broadcasting started at the metropolitan Seoul area and has expanded to the metropolitan area in 2004. However, until 2010 analog NTSC broadcasting will co-exist with digital TV. In this situation, digital TV may have the same channel as an analog NTSC broadcasting. To remove the effect of the analog NTSC intereference, DTV receivers adopt an NTSC rejection filter. In this paper, analysis on properties of the filter, such as a rejection property and noise performance degradation, is presented.
