This paper investigates the relationship between the Pay TV subscriber's genre preference and VOD purchase by analyzing actual purchase data of movie VOD of IPTV subscribers for 8 months. The result shows as follows. First, in case of purchasing movie contents below 4000 won, user's genre preference was higher than that of using contents over 4,000 won. This means the subscribers tend to follow their genre preference when the mass-typed recommendation is limited. Second, those who purchase foreign contents show higher genre preference than those who purchase domestic movies. Third, subscribers who purchase more frequently and much more tend to use more diverse genres. Heavy users or those who have higher willingness to pay would consume more diverse contents. It implies that VOD use would increase by supplying the personal recommendation service based on the subscriber's genre preference.

VOD 시스템에서 많은 클라이언트의 요청은 몇몇의 영화에 집중된다. 서비스 가능한 많은 영화 중에서 실제 서비스가 이루어지는 영화는 많지 않다. 본 논문에서는 이와 같은 특성을 고려하여 사용자에 의해 많은 요청이 이루어지는 영화만을 위한 미디어 가속기를 설계하고 개발한다. 기존의 시스템은 하드 디스크에 영화를 저장하고 서비스를 하는 반면 본 논문에서 구현하는 시스템은 많은 요청이 이루어지는 영화에 한하여 메모리에 영화를 저장하고 서비스를 한다. 본 연구에서는 미디어 가속기를 리눅스 환경에서 구현하고 실험을 통해서 실제 서비스가 가능한 사용자 수를 측정하고 서비스에 장애가 되는 요인이 무엇인지 알아본다.

In this paper, based on the relative logical storage cost of each movie by the difference of service request probability, we propose and implement the SDU(Separate Data Use) method and the EDU(Existing Data Use) method to provide FF(Fast Forward) and FR(Fast Reverse) function in efficiently through analysing MPEG bit stream and frame characteristics. By selecting and applying the FF/FR function providing method based on the service request probability of movie, the proposed method can reduce the cost of FF/FR functions for total serviced movies.

This study investigates the factors influencing to users' intention to retain monthly movie subscription VOD service in the Pay-TV. A dual model of a dedication-based mechanism and constraint-based mechanism used as the analytical framework for the service subscription retention. This study surveyed the total of 366 respondents who aged 15 years or older among the subscribers who use monthly movie subscription VOD service in Pay-TV from May 8 to May 14, 2018 through online surveys. And the study used SPSS 25 and AMOS 21 for data analysis. The results of the analysis are as follows. First, the price, the contents diversity and the ease of use were found to affect the user satisfaction. From three components, the price is the most effective and the ease of use is the next. Second, user satisfaction were found to affect the intention to retain a subscription in the dedication-based mechanism. Third, procedural switching cost were found to affect the intention to retain a subscription in the constraint-base mechanism.

The purpose of this study were to examine the spatial distribution and locational characteristics of the Internet movie industry, to seize the value chains of the Internet movie industry and distribution structure of the internet movies, and to analyze the vertical-horizontal linkages of the Internet movie firms and their spatial clustering. Recently, the Internet movie industry has developed rapidly due to the development of techniques related to movie contents, the broadband Internet and a wide expansion of the high speed communication network and the increase of demands on movie contents. It has been found that 74$\%$ of the Internet movie industry was concentrated in Seoul. Especially this industry was quite agglomerated in several dongs of Gangnam-gu such as Yoeksam, Nonhyeon, Daechi and Samseung. The proximity of the same or similar business firms was the primary locational factors that influenced on the Internet movie industry, followed by other factors such as convenience of transportation, the reputation of the place, and proximity of technically supporting firms. The Internet movie industry had the valve chain composed of 'contents suppliers $\rightarrow$ contents distributors $\rightarrow$ service providers', However, there were also a complex network of the VOD copyright owner, VOD syndicator, and service providers in each category of the value chain. This research clearly revealed that the localized clustering has been formed with the movie contents providers, technically supporting firms, client firms, and cooperative-affiliated business firms related to the Internet movie industry, Additionally, a very intimate network has been established within the clustering, inducing the enlargement of the market and decrease of costs, the co-sharing of tacit knowledge, and the synergy effect.

This study examined the importance of independent variables that affect users' preference on the VODs of the newly-released movies by using the conjoint analysis. The results demonstrated that 'price(44.6%)' is the most important variable, which is followed by 'device(24.5%)', 'recency(18.0%)', 'producing country(12.9%)'. Respondents obtained the relatively high utility from watching the VOD of a Korean movie currently on screen in 3,000 wons. A television set was the most preferable device for watching VODs. The traditional windowing strategy in the media content market has been recently challenged by the new trend that the holdback period between market windows is ignored and the high-priced content is found in the second window. Nevertheless, this study demonstrated that users of the VODs of the newly-released movies are still very sensitive to the price and consider 'the recency' to be relatively less important than 'price'.

D-CATV VOD service provides various contents such as drama and movie with high quality regardless of time and place. As the usage time of the VOD service increases, the viewing time of real-time terrestrial broadcasting is shortened. As the demand for VOD service is high and the number of digital users is increasing, the VOD market is rapidly growing. Therefore this study investigates the age and gender analysis of digital cable TV users and analyzed the usage patterns and audience cases of users. VOD service has been shown to be used by many users for the first time through remote control and free coupons. Non-users of VOD service did not use it because of charge and did not feel the necessity, but some non-users did not recognize the free VOD service.

This paper deals with a longitudinal time series study on the viewing behavior of digital media service. After holdback of terrestrial broadcasting VOD service was extended in 2013, viewers' terrestrial broadcasting VOD viewing went down sharply. Researcher assumed that there was driven by watching alternative products such as movies, kids, etc. as the cause of the decline of the terrestrial broadcasting VOD viewing. In addition, researcher assumed that the decline of terrestrial broadcasting VOD viewing had an influence on the viewing rate of the terrestrial real-time broadcasting, and confirmed the cause of the decreasing of the terrestrial real-time broadcasting viewing rate. In order for terrestrial broadcasters to retrieve real-time broadcasting and VOD viewing, it is necessary to shorten the VOD holdback and reacquire viewers away from terrestrial broadcasting.

KBS를 비롯한 지상파방송 3사는 실시간 UHD방송과 VOD 온라인 동영상 서비스가 결합된 세계 최초의 지상파 양방향 UHD 플랫폼인 Tiviva(이하 티비바) 서비스를 2017년 11월 오픈하였다. 티비바는 별도의 셋톱박스 없이 UHD TV에 직접수신 안테나와 인터넷을 연결하여 지상파 방송사의 실시간 방송 채널 외에 다양한 UHD VOD와 클립을 이용할 수 있고, 스포츠와 드라마, 종편(JTBC, MBN), 영화 등 50여 개의 IP채널을 추가로 볼 수 있는 서비스이다. 이후 2018년 1월에는 이용자 편리성과 자동추천 기능 등 UI/UX를 크게 개선한 티비바 2.0을 업데이트 하였고, 평창올림픽 기간에는 전 경기 실시간 스트리밍 및 올림픽특별관을 운영하였다. 2018년 6월 러시아 월드컵 기간에는 축구 경기 UHD HDR 방송 중계와 함께 티비바를 통한 HDR VOD를 최초로 서비스하여 스포츠 경기를 즐기는 또다른 즐거움을 선사하였다. 본 논문에서는 러시아 월드컵 HDR VOD 서비스를 준비하고 시행하기 위한 시스템 설계 및 진행과정, 기술 이슈 등에 대해서 기술하려고 한다.
