디지털 홈 시대의 도약으로 가정용 TV의 기능과 그 역할이 확대되면서 Digital TV(DTV)가 새로운 가전기기의 하나로 등장하게 되었다. DTV를 통한 디지털 데이터 방송뿐 아니라 웹 컨텐츠의 다양한 활용이 가능하게 되면서 기존의 PC 환경과는 다른 DTV 환경에 적합한 새로운 컨텐츠 표현 규격이 필요해졌다. 이에 다수의 디지털 데이터 방송 표준 단체들이 DTV를 위한 디지털 데이터 방송용 컨텐츠 표현 규격을 제시하고 있고, DTV가 등장하기 이전부터 TV와 웹의 접목 기술을 위한 W3C의 활동도 있어왔다. 또한 양방향 TV 서비스 또는 웹 TV 서비스를 제공하는 방법으로 자체적인 컨텐츠 표현 규격을 정의하고 브라우저 등의 프로그램을 통해서 시청자들에게 TV에 특화된 다양한 웹 컨텐츠를 제공하고 있다. 이에 본 논문에서는 현재까지 제시되어 온 DTV 또는 TV환경을 위한 컨텐츠 표현 규격들을 다양한 관점에서 비교 검토해보고자 한다. 또한 DTV가 가지는 특징들을 살펴봄으로써 TV와 다르고 또한 PC와도 다른 DTV만의 특성을 반영할 수 있는 컨텐츠 표현 방법을 제시하고자 한다. 이를 통해서 DTV 시장 활성화의 선두 위치에 있는 국내에서 DTV 용 컨텐츠의 표현 규격에 대한 보완 및 발전 방향을 숙고하고, 세계적으로도 앞서가는 인터넷 서비스 시장이 DTV를 통해서 안방에서 보다 효율적이고 간편한 방법으로 다양한 계층의 사용자에게로 확대될 수 있는 계기를 마련하고자 한다.

This paper defines markets relating to each paid broadcasting service by applying the test method of critical sales loss to the results of survey to the paid service subscribers. The result confirms the existence of a meaningful competitive relationship--in terms of the Competition Law--among all paid broadcasting services included in this study, or at least analog cable broadcasting, digital cable broadcasting, and real time IPTV(Internet Protocol TV) service. This indicates that current regulations which are being applied to cable TV, satellite broadcasting, and IPTV are actually discriminatory. Based on these analysis results, this paper suggests that the main attention for the improvement of regulations should be focused on regulations which are differently applied to different paid service providers. In particular, Article 20 in the Internet Multimedia Broadcasting Law is interpreted as defining the real-time IPTV as an independent market, thereby having leeway to harm fair competition among different paid service providers. Therefore, that article needs to change to give the right of equal access to contents to all the competing paid service providers. Furthermore, to put teeth in the contents equal access rule, most popular pay channels need to be designated as target contents of the rule. As for the market-share limitation regulations, the paper suggests that an upper limit on the market share should be set based on the total number of subscribers of all the competing paid services and the same limit applied to all the competing paid service providers.

This research examines the legal liability of place-shifting of TV contents by the use of the Slingbox. The place-shifting of TV contents is fair use because it is a non-commercial private use based on the relevant case law regarding time-shifting and device-shifting such as Sony, RIAA and Napster. But the sharing of place-shifting function is likely to be liable for copyright infringement. And place-shifting may not be fair use based on the cases which denied fair use of time-shifting and space-shifting because the consumers' convenience for the use of the copyrighted work is against the purpose of legislation of copyright law. Place-shifting is unlikely to have a significant effect on the potential market for TV contents because it presents lucrative new platforms to disseminate TV contents to computers and mobile devices. However it is likely to have negative effect because various devices can be the follow-up marketplaces of the copyright holders of TV contents. This study proposes the "innovative medium defense," a new doctrine to analyze liability of innovative media.

시청률은 각 방송사의 주요 수입원인 광고비 책정의 중요한 변수이다. 따라서 프로그램 편성자(Program Planner)는 경쟁 방송사의 편성을 고려한 시청률 최대화 전략을 수립하려 하며, 시청률 예측 모델을 사용하여 그 목적을 달성할 수 있다. 나아가 시청률 예측모델이 정확할수록 현재의 임의적인 광고비 책정 방식보다 정확한 광고비의 가격 책정이 가능해져 보다 합리적인 광고 및 미디어 시장 환경을 성립할 수 있다. 본 연구에서는 최근의 국내 TV 시청률 자료를 이용하여 국내 공중파 방송에 대한 시청률 예측 모델을 성립하고, 이를 이용한 시청률 최대화 전략을 제시한다.

This study explored the risk sharing mechanism in the US TV drama industry. The hollywood system of TV production and distribution can be understood to be the result of the efforts to reduce the uncertainty and the risk of investment. Since the 1990s, the vertical integration of major studios and networks has been one of the core strategies for risk sharing. In the strategy, the most important role of networks is to schedule new series that the affiliated studios produce. Networks also provide the new series their brand value. On the other hand, the most important role of studios in the vertical integrated environment is to provide the affiliated networks the infrastructures for production and distribution, financial management, and product management. In addition, networks keep the right on the series in the secondary markets, and attempt to increase the aggressive investment on new series on the base of the rights. However, such a risky investment can be the potential burden and risk for the networks in the future. This paper shows the importance of the reasonable risk sharing in the television drama industry to the Korean TV drama industry that has experienced the conflict between networks and independent production companies.

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.

Recently, mukbang and cookbang or cooking shows on TV and YouTube channels have increased, and the influences of these broadcasts on food consumption have been gradually increasing. There were several news articles on 'Baek Jong-won effect', in which the consumption of the agri-food Mr. Jong-won Baek mentioned on his broadcast soared, and even foods named after him are on the market. In this study, Mr. Jong-won Baek, who produces influential cooking contents through various media, was taken as a representative example. We evaluated if 'Baek Jong-won effect' exists on potato consumption, which Mr. Jong-won Baek broadcasted potato cooking recipes on TV and YouTube. After the potato recipe was broadcasted for the first time on the TV show called HomeFoodRescue, the differences in the amount of money to purchase potatoes before and after the broadcast were estimated by using the money amount to purchase data of Agri-food consumers panel and the difference-in-differences method at 6 time points (3, 6, 9, 12, 24, and 36 months). Among the time points analyzed, the potato purchases at post-broadcast were less than those at pre-broadcast. No results were observed suggesting the existence of 'Baek Jong-won effect' on potato consumption through HomeFoodRescue show in the study.

The purpose of this study is to research on the mechanism of exportation of Korean TV programs. As a result, the buying countries of Korean TV programs have been relatively diversified : 40 countries across the world. However, examining the frequency of exportation has shown that it primarily focused on few countries such as Japan and Taiwan. Furthermore, drama has been the most preferred genre by foreign countries. Fortunately, remakes, dubbing productions, publications, and merchandising have been started to develop. As for the trade partner, the portion of foreign distributors has been ranked as a the most prioritized type. Therefore, it is necessary to open the existing closed system of distribution of Korean free TV to build more diversified partnership.
