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.

In 1970s, Computer Graphics of still and geometry changed computer Animation of image, and Computer Animation has diversely been used in movie, TV, fashion, sports, education, basic science, medical science, etc. by the development of LSI technology and the large size of computer in 1980s. Since Computer Animation was first used by movie of Futureworld in 1973, we easily experienced the essence of Computer Animation made of the Little Mermaid. Beauty and the Beast, the Lion King, Aladdin, etc. in Disney Animation and Terminator. Jurassic Park, the Mask, etc. in movie. And in other countries that have got the diversely special effect and knowhow in technology are effectively using the Computer Animation now. What situation we Korea are in now, if we compare the Computer Animation with that of other country using the progressive movie\ulcorner Although we first producted the movie title of Ticket, 10years ago, we have rarely been used it in movie, yet. Therefore, we know that it is very important for us to examine the historical and technical side for the purpose of overcoming the technological gap.

As broadcasting and communication are converged recently, communication is jointed to TV. TV viewing has brought about many changes. The IPTV (Internet Protocol Television) provides information service, movie contents, broadcast, etc. through internet with live programs + VOD (Video on demand) jointed. Using communication network, it becomes an issue of new business. In addition, new technical issues have been created by imaging technology for the service, networking technology without video cuts, security technologies to protect copyright, etc. Through this IPTV network, users can watch their desired programs when they want. However, IPTV has difficulties in search approach, menu approach, or finding programs. Menu approach spends a lot of time in approaching programs desired. Search approach can't be found when title, genre, name of actors, etc. are not known. In addition, inserting letters through remote control have problems. However, the bigger problem is that many times users are not usually ware of the services they use. Thus, to resolve difficulties when selecting VOD service in IPTV, a personalized service is recommended, which enhance users' satisfaction and use your time, efficiently. This paper provides appropriate programs which are fit to individuals not to save time in order to solve IPTV's shortcomings through filtering and recommendation-related system. The proposed recommendation system collects TV program information, the user's preferred program genres and detailed genre, channel, watching program, and information on viewing time based on individual records of watching IPTV. To look for these kinds of similarities, similarities can be compared by using ontology for TV programs. The reason to use these is because the distance of program can be measured by the similarity comparison. TV program ontology we are using is one extracted from TV-Anytime metadata which represents semantic nature. Also, ontology expresses the contents and features in figures. Through world net, vocabulary similarity is determined. All the words described on the programs are expanded into upper and lower classes for word similarity decision. The average of described key words was measured. The criterion of distance calculated ties similar programs through K-medoids dividing method. K-medoids dividing method is a dividing way to divide classified groups into ones with similar characteristics. This K-medoids method sets K-unit representative objects. Here, distance from representative object sets temporary distance and colonize it. Through algorithm, when the initial n-unit objects are tried to be divided into K-units. The optimal object must be found through repeated trials after selecting representative object temporarily. Through this course, similar programs must be colonized. Selecting programs through group analysis, weight should be given to the recommendation. The way to provide weight with recommendation is as the follows. When each group recommends programs, similar programs near representative objects will be recommended to users. The formula to calculate the distance is same as measure similar distance. It will be a basic figure which determines the rankings of recommended programs. Weight is used to calculate the number of watching lists. As the more programs are, the higher weight will be loaded. This is defined as cluster weight. Through this, sub-TV programs which are representative of the groups must be selected. The final TV programs ranks must be determined. However, the group-representative TV programs include errors. Therefore, weights must be added to TV program viewing preference. They must determine the finalranks.Based on this, our customers prefer proposed to recommend contents. So, based on the proposed method this paper suggested, experiment was carried out in controlled environment. Through experiment, the superiority of the proposed method is shown, compared to existing ways.

Reportage documentary by SBS did a great role to keep public sphere whether other programs shrinked during 2010's. I analysed with the assumption that there are some rhetorical characteristics in narrative structure of . Looking as 'Mysterious reportage documentary' I analysed the rhetorical characteristics of title, subtitle and script. Title has a perspective to suffice audience's desire and subtitles uses word 'mystery', names of place, interrogative sentences very often. This use helps to draw and keep audience's attention. I found reversal of fortune rhetoric, into depth rhetoric and admiration rhetoric salient. These results connect to the design thinking approach which shed light on importance of person, and we could get an implication of the successful development of television contents.

We present the seamless browsing - a new Zooming technique based on the zoom ratios and the distances of the hyperlinks from the pointer. In most cases, users have to activate the interesting link after guessing the target content of it, just based on the insufficient information from the link label or title. We propose that a web browser displays a limited number of hyperlinks in an area around the pointer in a distinguished way, e.g. in different sizes of thumbnails, transparency or style. If a user zooms in on the pointer area, to new web browser displays the varying images of hyperlink-targets according to the zoom ratio, and finally it transfers to the new target page which was nearest to the pointer position. This method allows users to easily select a hyperlink based on rich information given by zoomable thumbnails and seamlessly to transit through web pages just with zooming. 1n our experiments, results show that the seamless browsing significantly outperforms the legacy way.

In this study, we attempt to propose a choice-based diffusion model with switching cost, which can be used to forecast the dynamic substitution and competition among previous and new products at both individual-level and aggregate level, especially when market data for new products is insufficient. Additionally, we apply the proposed model to the empirical case of substitution and competition among Analog Cable TV that represents previous fixed charged broadcasting service and Digital Cable TV and Internet Protocol TV (IPTV) that are new ones, verify the validities of our proposed model, and finally derive related empirical implications. For empirical application, we obtained data from survey conducted as follows. Survey was administered by Dongseo Research to 1,000 adults aging from 20 to 60 living in Seoul, Korea, in May of 2007, under the title of 'Demand analysis of next generation fixed interactive broadcasting services'. Conjoint survey modified as follows, was used. First, as the traditional approach in conjoint analysis, we extracted 16 hypothetical alternative cards from the orthogonal design using important attributes and levels of next generation interactive broadcasting services which were determined by previous literature review and experts' comments. Again, we divided 16 conjoint cards into 4 groups, and thus composed 4 choice sets with 4 alternatives each. Therefore, each respondent faces 4 different hypothetical choice situations. In addition to this, we added two ways of modification. First, we asked the respondents to include the status-quo broadcasting services they subscribe to, as another alternative in each choice set. As a result, respondents choose the most preferred alternative among 5 alternatives consisting of 1 alternative with current subscription and 4 hypothetical alternatives in 4 choice sets. Modification of traditional conjoint survey in this way enabled us to estimate the factors related to switching cost or switching threshold in addition to the effects of attributes. Also, by using both revealed preference data(1 alternative with current subscription) and stated preference data (4 hypothetical alternatives), additional advantages in terms of the estimation properties and more conservative and realistic forecast, can be achieved. Second, we asked the respondents to choose the most preferred alternative while considering their expected adoption timing or switching timing. Respondents are asked to report their expected adoption or switching timing among 14 half-year points after the introduction of next generation broadcasting services. As a result, for each respondent, 14 observations with 5 alternatives for each period, are obtained, which results in panel-type data. Finally, this panel-type data consisting of $4{\ast}14{\ast}1000=56000$observations is used for estimation of the individual-level consumer adoption model. From the results obtained by empirical application, in case of forecasting the demand of new products without considering existence of previous product(s) and(or) switching cost factors, it is found that overestimated speed of diffusion at introductory stage or distorted predictions can be obtained, and as such, validities of our proposed model in which both existence of previous products and switching cost factors are properly considered, are verified. Also, it is found that proposed model can produce flexible patterns of market evolution depending on the degree of the effects of consumer preferences for the attributes of the alternatives on individual-level state transition, rather than following S-shaped curve assumed a priori. Empirically, it is found that in various scenarios with diverse combinations of prices, IPTV is more likely to take advantageous positions over Digital Cable TV in obtaining subscribers. Meanwhile, despite inferiorities in many technological attributes, Analog Cable TV, which is regarded as previous product in our analysis, is likely to be substituted by new services gradually rather than abruptly thanks to the advantage in low service charge and existence of high switching cost in fixed charged broadcasting service market.

This paper begins with the notion of 'pick-me generation', which refers to today's young generation in Korea. It is named after the title of a song introduced at the Television programme for the competitive audition for girl-group singers. This name gives an idea of the atmosphere of the competition that the current young generation experiences in South Korea. In parallel to it, the research examines the meaning of freedom and choice in democratic education in Oh Chunsuck, in his later work in particular. This paper attempts to demonstrate the possibility to relate Oh's notion of freedom and democracy in relation to Han who critically analyses contemporary discourses on neo-liberalism and democracy. This paper re-views Oh's ideals of democracy and education within its own limitations on freedom. The argument extends Oh's idea of freedom and ethical democracy to the idea of freedom that is relevant to today's younger generation.

Recent advances in the media have no special change is the development of the 3D stereoscopic image, which started in the movie is coming over now to the broadcast. Confusing variety having, in the production of 3D images that are waiting for the standardized production. 3D images of them being used in broadcast subtitles, first because there is no standardized production systems, making it look is dedicated to the time and effort. This research necessary to create 3D images of these subtitles, titles, text-based objects, such as Rig imaging using a standardized way to synthesize the most stable is proposed. First, with captions or titles, and the readability and understanding of the uniqueness to the human eye to create an environment that is kind of crowd. Because of this, excessive camera Ferrell Rex (gap) created a branch bunch of snow, work should not hurt readability. 100 adult men and women throughout the experiment.

Purpose: The purpose of this study is to confirm that multichannel distribution strategies may be used for cultural and artistic products such as musicals, just as for general consumer goods, through a case study on the distribution strategy for a musical title. In addition, a distribution strategy for cultural and artistic products is proposed based on the analysis of the case. Research design, data, and methodology: Qualitative research methods, such as case study research and in-depth interviews, were used in this study. Results: The case study of the Korean musical Myeongdong Romance confirmed that multichannel distribution strategies may be used for musicals, including performances at theaters, Naver TV screenings (a service linked to an Internet portal), LGU+ screenings (an IPTV and OTT media service), DVD releases, and screenings of recordings of Romance Hall performances. Conclusion: For cultural and artistic products such as musicals, distribution channels can be diversified to incorporate the simultaneous use of multiple channels. New cases involving other cultural and artistic products and services to which this distribution strategy is applicable may be identified, and the strategy may be implemented along with new technologies to reduce costs further.
