IPTV는 기술적으로 TV에 PC적 기능이 더해지고 인터넷 프로토콜(IP)을 통해 인터넷과 연결되는 서비스로, 국내 초고속인터넷의 속도가 VDSL, 광랜과 같은 서비스의 등장으로 최대 100Mbps에 이르러 동영상 콘텐츠의 실시간 스트리밍 서비스가 가능한 환경이 구현되었다. IPTV 도입을 통해 산사건 방송, VOD 등의 기본적인 서비스뿐만 아니라, 양방향 광고, IPTV 민원발급 및 IPTV 공공서비스 제공 등 다양한 응용서비스의 개발 및 활성화를 기대하였다. 또한 IPTV를 통해 유료방송의 경쟁을 촉진시키고 케이블TV의 디지털 전환을 촉진시킴으로써 시청자들의 복지를 향상시킨다는 취지도 함께 있었다. 정량적으로는 IPTV가입자가 2012년에 이르러 보수적으로 290만가구, 낙관적으로는 450만 가구에 이를 것으로 예상하였으며, 관련 시장규모도 동년도에 약 7,515억원에 이를 것으로 전망하였다. 하지만, 2011년 말이 이미 450만 가입자를 돌파하고 2012년 8월 500만 가입자를 유치하면서 IPTV 서비스는 본격적인 mass market을 형성해 나가고 있다. IPTV 시장이 확대해 나가면서 유료방송 가입가구 수도 증가하였는데, 도입당시인 2008년 말 1,740만 가구가 유료방송에 가입하여 104%의 보급률을 보였으나 2011년 6월말 현재 가구수 대비 유료방송 가입자구수는 127%로 증가하였다. 이렇게 IPTV서비스 시장이 확대되고는 있으나, 정부의 신규 서비스에 대한 과도한 요금규제, IPTV와 경쟁하는 케이블방송사(SO) 계열의 콘텐츠 사업자(CP)들의 방송채널 공급거절 및 지상파 방송사의 과도한 재전송 대가, 전국 권역사업자인 IPTV에 대한 권역별 가입자점유율 규제, IPTV의 차별성으로 내세웠던 T-Commerce 및 양방향 광고에 대한 규제는 앞으로 개선해 내가야할 과제이다. 이에 본고는 IPTV의 시장성과를 조망하고, 시장의 지속성장을 위해 필요한 제도개선 방향을 살펴보았다.

This study critically reviews the justifications for the restriction of cable local channel's news commentary function in terms of the fundamental principle of journalism. By doing so, it tries to find some problems and ways to solve them. Broadcasting Law and Korea Communications Commission's Rule inhibiting the news commentary of cable local channel on specific issues conflict with the basis of journalism which is particularly represented in Broadcasting Law. The law and rule tend to solidify public opinion for vested rights of local worthies. In addition, they are likely to degenerate cable local channel to the tools for promoting local government. Therefore, this article proposes the revision of the law and rule towards permitting the news commentary of cable local channel. At the same time, it suggests a new broadcasting policy for inducing cable local channel to increase manpower resources and production investment.

This study examines the effect of changes in the content distribution strategy on VOD usage by comparing the VOD usage pattern following the changes in the IPTV and Digital Cable SVOD holdback policy. The result of this study shows that after changing the SVOD holdback from one week to three weeks, the VOD usage decreased up to 50 percent while paid VOD revenue increased as a result of the rise in PPM. The time series analysis shows statistical decrease in the number of SVOD usage, SVOD usage per user, and PPV revenue per user while VOD revenue per user increased significantly. Moreover, SVOD usage within the drama genres such as mini-series, weekend series, weekend special series, and sitcom decreased significantly. This research provides a case study on the effect of the broadcaster's content distribution policy on the VOD user behavior thus proposing broadcasters and platform operators the ways of establishing distribution strategy as well as invigorating the VOD usage.

With the question, "What would be the difference between TV drama image production techniques under the changing circumstances of domestic broadcasting faced with multi-media, multi-channel age after 1980' s press unification and establishment of two times commercial TV stations?" This study analysed image production techniques of three periods of TV drama development, 'TV drama maturity period(1981-1990)', 'TV drama transition period(1991-2000)', 'TV drama take-off period(2001-)'. For the image analysis within the genre of home drama, 3 dramas for each period were selected and analysed cameraworks, shot size, shot duration with the broadcasting station's DVD, homepage and manuscript. The result of this analysis revealed that the change of shot size was slight but the change of cameraworks was great, the usage of zoom and tilt diminished but the usage of dolly and track increased. and the average shot duration drastically diminished during the take-off period. These results show us that broadcasting production equipments developed during the periods, and broadcasting stations poured all-out efforts for the higher viewing rates and international competitiveness.

IPTV is referred to the service which provide integrated IPTV services for providing video, 10/100-Mbit/sec Internet, voice, video-on-demand (VOD), and other broadband applications including home security, video conferencing, and telemedicine. All services are integrated into an IP (Internet Protocol) architecture designed specifically for Gigabit Ethernet FTTH systems, HFC or xDLC. It is absolutely necessary that telecon operators provide IP video delivery platforms that enable service providers to transform their business. With their own products, they can better manage their existing services and generate new revenues from broadcast TV, movies on demand and multimedia. Triple-play is a combination of broadcast, telephony and broadband services offered through IPTV networks. With cable operators allowed to offer a triple-play bundle, the nation's telecom operators are beginning to get a little anxious. Cable operators assert that triple-play is a must-have and natural extension of the cable service bundle. The Korean Cable TV Association asserts that the triple-play model is of paramount importance to the cable industry's future growth. But the telecom sector considers itself unfairly disadvantaged, saying they cannot compete until regulatory issues are resolved. The start of web-based television in Korea may still be some time off with a confrontation between the nation's IT regulator and broadcasting sector over the service's legal boundaries shows no signs of being resolved my time soon. korea should be is the fastest-growing provider of IPTV solutions in the industry, with over worldwide customers.

The purpose of this paper is to provide an answer for the following question: What are the major shifts and implications of the unprecedently competitive and rapidly changing media ecosystem in the era of N-screen and OTT services? I've attempted to understand the complex and competitive nexus among media from an historical context by focusing on the displacement vs. complement thesis. The TPC model by Han has been employed for the analysis of the current dynamics of US media industries by triangulating three areas: Technology/industry, public policy and consumer/culture. More specifically, the US media landscape is initially divided into two competitive turfs - the competitors equipped with OTT services and the legacy media industry, and then the traditional media industry was grouped again into PayTV group(telecom service providers with IPTV and mobile TV, cable/Satellite TV networks) and Free (over-the-air) TV networks. Six major shifts were identified by the analysis: power shift in telecom carriers, power shifts in TV industry, Telecom/OTT partnership, time shifts, place shifts, and finally business model shifts.

This paper focuses on effects that IPTV will have on domestic broadcasting market in the point of view of customers. The purpose of the paper is to present the future landscape of competitive media market when IPTV is launched, and to research how IPTV will have impact on terrestrial broadcasting, cable TV and satellite broadcasting industry. The paper integrates two known theories, such as the niche-gratification model and the value-expectancy model, to analyze competitive media market. The value expected model makes it possible to overcome the weakness of the niche-gratification model and to forecast competitiveness more accurately. According to this research, competitive power will be in the order of Cable TV, IPTV, and satellite broadcasting. Terrestrial broadcasting does not show strong competitive relationships with others statistically. As a result, Cable TV will be the most competitive medium in the future. IPTV will be stuck in the middle and can rapidly substitute for existing broadcasting services. While IPTV will severely threaten the satellite broadcasting company which has a relatively small number of subscribers, cable TV will be in a superior position to IPTV.
