The new HDTV technologies provide crystal clear images and surrounding sounds for broadcasting screen in order to serve higher quality of broadcasting. They have four times the resolution of conventional TV and handle 16:9 wide screen aspect ratio images. Due to such technological shift, the function of Character Graphic has been particularly revaluated: it used to be only a subsidiary method to literally deliver visual images, but nowadays it is considered one of the essential elements capable of giving higher values to broadcasting programs. And there is an urgent need for changing its attributes such as fonts, sizes, colors, moving speeds to fit to bigger screen ratio and much more qualified images of HDTV. To meet such a need, Delphi surveys are made twice with three groups of TV production staffs: Art Directors, CG Designers and Production & Transmission team, these groups which are divided on the basis of their roles in broadcasting production process. With the results of these surveys, this article analyzes how all of the attributes of Character Graphic have affected the media users' Visual Perception, and then, suggests a new format designed in OSMU(One Source Multi Use) by which TV character graphics can be properly transmitted to various media formats.

As the broadcasting system rapidly migrates to the HD contents production, a broadcasting professional training program has increasingly requested, which provides a professional ability keeping up with new demands and a systematic well-organized education program. This paper utilized a DACUM(developing a curriculum) method for a video editor's job analysis and presented a job model of video editing. With a DACUM job analysis, we retrieved 9 essential job duties and 71 tasks, and then examined their importance, difficulty, frequency, and entry level tasks that are required before job hire. We also established a well-form structure of the job analysis results, completed a DACUM research chart, and consequently built a video editor's job model in TV broadcasting and video production areas. The proposed model is expected to be used as a fundamental material for a future job organization of video editors in TV broadcasting and video production areas, a development of the educational curriculum, and a priority decision of on-the-job training programs.

We suggest that cultural differences among nations should have a significant impact upon the exports of Korean broadcasting contents due to the fact that production and consumption of the contents are influenced by their own cultural aspects. Based on Hofstede's cultural dimensions frequently cited in the literature, we perform empirical analysis to identify the impact of cultural dimensions upon the export amounts by investigating four-year export data of Korean broadcasting industry. In our research model, Hofstede's cultural dimensions and GDP per capita are independent variables and a genre of broadcasting contents is used as a moderating variable. We find in our analysis that three cultural dimensions such as individualism, uncertainty avoidance, masculinity significantly affect the export amount but do not find the impact of power distance.

According to appearance of digital broadcasting media such as DTV, IPTV, DMB, and so on, the needs about digital contents have been increased. The cases reusing the producted contents happen frequently, in consideration of the production cost of digital contents and the early digital broadcasting market. In this case, the reused contents must adjust the transfer rate of the digital broadcasting system. The time information included in the contents is shifted in the adjusting process. This paper proposes the efficient method correcting the shifted time information.

This paper introduces interactive multi-view contents authoring system based on MPEG-4. The MPEG-4 standard, which aims to provide an object based audiovisual coding tool, has been developed to address the emerging needs from communications, interactive broadcasting as well as from mixed service models resulting from technological convergence. Due to the feature of object based coding, it has been considered that MPEG-4 is the most suitable for interactive broadcasting content production. This feature is suitable for creation of the content which provides multiple views of object or scene in interactive manner. In this paper, we categorize the multi-view visual content into two types: panoramic multi-view content and object multi-view content. And design and implementation of the authoring system for interactive multi-view contents is presented. We believe that the proposed method can be effectively used for further deployment of MPEG-4 content to various interactive applications.

The MPEG-4 standard is aimed to define an object based audiovisual coding standard to address the emerging needs from interactive broadcasting. Since a broadcasting program is created on the basis of its objects, it is considered that MPEG-4 is most suitable for interactive broadcasting contents production and it can be retrieved in terms of its properties. But, there is no system that protects the copyright of digital contents and manages copyright and possibility that contents producer and author's copyright receives infringement at process that exchange contents mutually rose very. Therefore, we need to control and distribute contents according to user's permission rights. In this paper, we present the authoring system based on MPEG-4 IPMP for copyright and protection of MPEG-4 contents. The main features of the proposed approach is to provide an MPEG-4 compliant IPMP authoring system in a plug-in type along with standardized interfaces, which is to be able to incorporated into an existing MPEG-4 content authoring system. In this way, it is capable of authoring content to the MP4 file format while accommodating protection and management of content in a unified way. Furthermore, it also allows a user to edit and/or author IPMP information in a more efficient way by offering form based user interfaces.

What is the basic nature of Korean public broadcasting system? This research explores this question through an analysis of KBS news coverage of the Korean housing market. This study spotlights the internal news production processes. In detail, this study investigates newsroom routines, such as news selection, news gatherings, and news production. As a result, this study reveals KBS can be classified as "Publicity Model" following reasons. First, KBS news selection process stresses higher viewer ratings for competitive market share and belittles public interests of serving the citizen. This caused KBS news to provide fragmented and truncated news information and to constrict high quality news of significant information for citizen. Second, KBS newsroom operates under the minimum staff resource to produce news programmes and has developed official source dependency as a routine for news gathering. Third, under the limits of report format, KBS news worked as a neutral deliverer of government message and failed to provide more detailed information and diverse viewpoints.
