This study examines demand of the Korean TV VOD using monthly aggregate data and time series analysis models. In particular, the impact of box office attendance, number of IPTV subscribers, income and price of substitutes on TV VOD market is analyzed. Data on TV VOD download during the period 2013 January to 2018 June are used for the empirical analysis. TV VOD demand shows lower level of seasonality than box office attendance and the share of monthly top1 movie in TV VOD platform is also lower than that of box office attendance. The relationship between a movie's holdback and box office performance does not seem consistent. The empirical result of ARDL model reveals that in the short-run box office attendance, number of IPTV subscribers and price of substitutes have significant impact on TV VOD demand. The result on the long-term relation shows that income is the only determinant of TV VOD demand. The impact of box office attendance on TV VOD is not shown to be robust both for the short-term and long-term.

Recently OTT video service has grown rapidly and has a negative impact on the growth of pay-TV subscribers. Consequently the substitution of OTT services for pay-TV services will begin. This study explores OTT usage patterns, dividing into three sectors (OTT service use, OTT usage volume, and paid-OTT service use), by considering users' demographice factors, smart device ownership, pay-TV subscription, and bundle service use, by employing the Mediapanel dataset. The results showed that age, income, smartTV usage, market size, cable/satellite subscribers, TV VOD expenses, movie VOD expenses, and mobile bundle use are associated with OTT service use. The results also showed that age, household sizes, tablePC usgage, cable/satellite subscribers, TV VOD expenses, other VOD expenses, and unlimited data plans are associated with OTT usage volume. Lastly the results showed that age, gender, income, tabletPC usage, cable subscribers, other VOD expenses, mobile bundle usage, and unlimited data plans are associated with paid-OTT service use.

With technological development including digitization, movie demand and supply in digital online movie market are increasing. This study aims to explore demand concentration of the digital online movie market, which is characterized by product variety compared to cinemas. Major findings of the empirical analysis on the TV VOD data during the recent seven years(2013 ~ 2019) are as follows. First, the analysis on 1,137 titles reveals that movie demand of theatrical market is more concentrated than that of TV VOD. Second, absolute long tail index of TV VOD, measured by the download number of indie & artistic movies(niche product), is increasing as more such movies are released in the market. However, both relative long tail index, measured by the share of indie & artistic movie demand, and top-ranked movies' share do not show consistent increase or decrease trend. Third, regression analysis exhibits that the relationship between demand concentration and market size is insignificant for TV VOD market. This study might have usefulness in that it provides empirical evidence for the nature of the Korean digital online movie market.

Smart TV is rapidly growing with the provision of OTT services, and has become an alternative to pay-TV services. Yet smart TV in Korea has been diffused slowly, and thus few research has paid attention to smart TV. With the global growth trend of smart TV, research on smartTV, focusing on users' characteristic and their behaviors, is critical to explain smart TV's usage. To employ the Mediapanel dataset, this study explores the impact of smart TV users' demographic factors and their pay-tv usage on smart TV usage. The results suggested that age, the type of household, household income, and market size are associated with smart TV usage. Pay-TV usage, specifically IPTV subscription and VOD expenses, have impacts on smart TV usage. Lastly the interaction effect between IPTV subscription and movie VOD expenses, has negatively associated with smart TV usage. This study may bring to re-attention to smart TV and to give insights into the industry field.

As the subscribers of the digital cable and IPTV broadcasting are increasing, the VOD service has established a solid foothold as a profit model of the broadcasting industries. And what's more, the VOD service is emerging as a key application of the N-screen technologies. In the circumstance, broadcasting companies are trying to provide mobile services to improve the satisfaction of their VOD services usage. The paper introduces a VOD mobile app (of a domestic digital cable broadcasting), which includes the functions of promoting the VOD programs printed on a VOD guide book, directly transmitting the information (e.g., book-marking, remote-control signals) generated by the VOD mobile app to a set-top box, and watching the video contents stored in the mobile device on TV.

In recent, the rapid convergence of telecommunication and broadcasting has been considered as one of the hot issues in the IT industry. This convergence will provide telecom operators with both opportunities and threatens. This is because that telecom operators can enter the broadcasting industry, whereas broadcasters will also have a chance to provide telecom services. This work aims to discuss the business strategy for telecom operators to provide a TV VOD service, one of the convergence services between telecommunication and broadcasting, through the high-speed internet which is so much served in Korea. It seems that this service will achieve two business goals, namely "to minimise an additional investment" and "to find out a new benefit source", by fully utilising a current high-speed internet infrastructure. Finally, this paper mainly contains the market overview of in telecom and broadcasting service, the definition of TV VOD service and the necessity for this service, a market forecasting and the provision strategy of major telecom operators, and key success factors and a benefit model.

Collaborative filtering(CF) for the personalized recommendation is a successful and popular method in recommender systems. But the mainly researched and implemented cases focus on dealing with independent items with explicit feedback by users. For the domain of TV program recommendation in VOD service platform, we need to consider the unique characteristic and constraints of the domain. In this paper, we studied on the way to convert the viewing history of each TV program episodes to the TV program preference by considering the series structure of TV program. The former is implicit for personalized preference, but the latter tells quite explicitly about the persistent preference. Collaborative filtering is done by the unit of series while data gathering and final recommendation is done by the unit of episodes. As a result, we modified CF to make it more suitable for the domain of TV program VOD recommendation. Our experimental study shows that it is more precise in performance, yet more compact in calculation compared to the plain CF approaches. It can be combined with other existing CF techniques as an algorithm module.
