  • The progression of broadcasting technology changed the previous analogue broadcasting system into digital, which in result allowed several broadcasting programs to be transmitted as one stream by multiplexing. This multi channel environment interferes with audience to choose the program they want. EPG acts as supporter in this multi channel environment. The existing EPG system is limited in providing searching function with title, genre, date and Wish-list in multi-media environment. Thus, this thesis proposes new type EPG using PSIP information modification to respond with the change of broadcasting market. This type of EPG can be applied to several kinds of broadcasting systems.

  • UHD(Ultra High Definition) Broadcasting is the focus of attention recent days. However, current broadcasting system faces with difficulty of bandwidth, encoding and so on. To solve this problem, MMT was suggested as the one of solutions. MMT is designed to be based on IP network and it has characteristics that can deliver multimedia through many networks at the same time. UHD Media service can be available with the current broadcasting system that divides media data into hierarchical data based on MMT. To provide this service, information about heterogeneous network should be delivered and signalling should be given to perceive it. For UHD media data service, the information about data from heterogeneous networks should be transported for providing presentation information and service for the receiver models. The present MMT signalling has not much information about heterogeneous services with hierarchical media data. In this paper, we suggest the design of service signaling structure based on MMT for UHD broadcasting systems.

  • This study is to consider the major policy issues related to 3DTV in terms of the platform projects, not the terminal and equipment manufacture. It reviews what problems the 3D policy in terms of the platform projects has posed so far, and discusses the issues that may appear when the 3D TV is commercialized in the broadcasting market. The major issues dealt in the study include the frequency policy of the terrestrial platform, the additional services activation of the pay platform players, the retransmission policy of terrestrial broadcasting, and the advertising market policy.

  • Digital TV tuner for 8-VSB modulation was developed with satisfying the requirements of ATSC. Double frequency conversion and active tracking filter was used in order to suppress IF beat and image band, which results in reducing the interference between adjacent channels and multi-channels. The implemented digital TV tuner has excellent performance such as the wide dynamic range, good flatness in passing band, and low phase noise. The developed tuner is available to handle the digital and analogue television signal at the same time.

  • The aim of this paper is to develop a framework of weather information services which is for processing contents and providing proper contents to new-media such as outdoor electronic display, DID (digital information display), and terrestrial multi-channel broadcasting, etc. By introducing the analysis of media use and perception science of human intelligence, the contents producing method to improve recognizing rate for weather information is provide and the layered framework of weather information services for new-media is designed. It integrates many different services to the framework. It can prevent duplicate investment for services and serve a major momentum to technical progress.

  • With the advent of the digital broadcasting, the audiences can access a large number of TV programs and their information through the multiple channels on various media devices. The access to a large number of TV programs can support a user for many chances with which he/she can sort and select the best one of them. However, the information overload on the user inevitably requires much effort with a lot of patience for finding his/her favorite programs. Therefore, it is useful to provide the persona1ized broadcasting service which assists the user to automatically find his/her favorite programs. As the growing requirements of the TV personalization, we introduce our automatic user preference learning algorithm which 1) analyzes a user's usage history on TV program contents: 2) extracts the user's watching pattern depending on a specific time and day and shows our automatic TV program recommendation system using MPEG-7 MDS (Multimedia Description Scheme: ISO/IEC 15938-5) and 3) automatically calculates the user's preference. For our experimental results, we have used TV audiences' watching history with the ages, genders and viewing times obtained from AC Nielson Korea. From our experimental results, we observed that our proposed algorithm of the automatic user preference learning algorithm based on the Bayesian network can effectively learn the user's preferences accordingly during the course of TV watching periods.

  • This study attempted to analyze background and industrial difference of RO and SO. RO was launched for solving a problem of terrestrial broadcasting. After solving a problem of terrestrial broadcasting system, RO has played a roll as a local media. On the other hand, SO was launched by government's policy so SO has been protected and brought up by government. Because market of RO and SO is overlap and competitive, RO has been restricted by government for issuing new license and renewal of permission. Presently, environment of media has been changed very dramatically, so various niche media are needed for various customer's needs. In addition, local media are in trouble of playing a role as a public broadcasting service in Korea. Therefore, RO might be a good solution. In this study for the analysis of the user's needs a survey was conducted. This study shows possibility of RO's roll and function as a local media.

  • This study analyzed the impact of social trust and conflict perception of news users on news use. To this end, 548 adults aged 20 and under 69 were surveyed online. The analysis results are as follows. First, the level of awareness of social conflict has been shown according to people's political orientation. Second, the higher the trust in society, the greater the use of news regardless of land-based, comprehensive, and online channels. Third, the perception of social conflict was related to the use of news through JTBC, TV Chosun, Channel A and YouTube. Fourth, the age and political orientation of news users influenced the use of news by channel. Finally, the more progressive the tendency was to use news through JTBC or to watch news on portals. On the other hand, the more progressive the use of news through three terrestrial broadcasters, TV Chosun, and Channel A decreased. In conclusion, this study is meaningful in terms of the user-oriented discussion of the news environment and the impact of an individual's social perception on news use.
