The convergence in telecommunication and broadcasting is one of the most popular topics in these days. For example, the characteristic of IPTV -internet protocol television-is controversial in the extreme. In Korea the IPTV operators are mainly the telecommunication service operators. So it is natural that the IPTV services are categorized to the telecommunication services. But the Broadcasting service providers, especially the CATV providers who can serve the TPS-triple play service- like IPTV players insist that the IPTV should be regulated as a broadcasting service. This paper will analyze whether the regulation in which the IPTV is categorized to one of the broadcasting services is better than the case of telecommunication services. To examine this, the social welfare analysis is conduced and the differential oligopoly market model is used. Together with that, this paper suggests that we can improve the social welfare by the asymmetric regulation between IPTV and D-CA TV. This means that in Korea the IPTV has a weak substitution relation with the D-CA TV and the IPTV should be dealed as a new convergence service that differs from traditional broadcasting services.

The charged broadcasting market has been becoming very competitive to get the limited media consumers since IPTV was introduced to the market. This research analyzed the competition among interactive broadcasting media. We employed the niche theory for comparing IPTV with Cable TV and Satellite TV, which are two major existing broadcasting media. For employing the niche theory, we focused on the gratification-opportunity features of the media caused by the consumers' gratification sought: ease of use, interactivity, variety of content, and economic feasibility. The results showed the extent to which media are utilized, the extent to which each pair of media are perceived as similar, and the competitive superiority between each pair of media on each dimensions. Finally, we examined the competition structure of IPTV and other broadcasting media, and proposed the competitive strategy for IPTV to get an advantages.

Since 2008 when IPTV service entered the broadcasting market, the competition among interactive broadcasting media has been growing more and more fierce. To make a market strategy under the harsh competition, this study tried to make an IPTV customer segmentation based on the characteristics of interactive broadcasting media. From previous literature, this study drew five characteristics of interactive broadcasting media : ease of use, two-way communications, active control, variety of content, and economic efficiency. Two-step clustering based on these characteristics identified four customer segments. There were statistically significant differences in the five characteristics among the customer segments. This study profiled the customer segments and proposed competitive strategies for each customer segment.

As one of leading media converging broadcasting and telecommunications, IPTV is required to pursuit the idea of public interest from broadcasting industry and universal service from telecommunications industry as well as satisfying industrial effect. It needs to consider both industrial effect and public benefit when vitalizing IPTV services. The project of providing IPTV-based interactive public services is expected to enhance accessibility of public services, present shape of new public service in broadcasting-telecommunication convergence environment, resolve the shortage in contents supply which is one of most important problems in IPTV services. In this research understanding the overall response such as service usage status, satisfying/dissatisfying factor, trend of preference of the customer using IPTV-based interactive public services, we analyze what the public service mean in IPTV environment and public identity of IPTV. And we have investigate effective developing method and ripple effect of IPTV-based public services on broadcasting and telecommunications converged ecosystems.

This study investigated users' usage of mobile video service, users' perception and usage of mobile IPTV. The results show that 82.8% is using mobile video services and 33.6% of the entire respondents has the intention to use mobile IPTV with regards to future usage. They answered that 'various real-time broadcasting' and'mobile IPTV charges' were the major areas of considerations for mobile IPTV users. And we analyzed the most watching contents on mobile IPTV and the willingness to pay for one month. In addition, the main reasons for not using mobile IPTV were the charges for mobile IPTV. Based on these results, action plans for the promotion of mobile IPTV are proposed.

The convergence of broadcasting and telecommunication services is being accelerated by broadband networks, digital broadcasting and Web2.0. This paper describes the definition and service characteristics of IPTV as a representative of broadcasting and telecommunication convergence services. Especially, the changes of infrastructure and technology for IPTV2.0 are addressed in terms of the service features of mobility, intelligence and participation. IPTV2.0 shall be characterized by the open IPTV service based on Web2.0 and the mobile IPTV service over the heterogeneous networks employing various wireless/wired access technologies. The IP Multimedia Subsystem (IMS) and Service Delivery Platform (SDP) technologies are increasingly considered to support the personalization and openness. The mobility management technology is being evolved to provide QoS-guaranteed mobile communication services to users at anytime and anywhere. IPTV2.0 services and platforms are also anticipated to be core components to achieve knowledge-based ubiquitous society. IPTV2.0 contents are required to be integrated with the enhanced metadata to efficiently support search, selection, convergence and delivery of the contents. Moreover, those contents shall be enhanced to provide the scalable services which is adaptable to the network status and user preferences. Therefore, the networking technologies for IPTV2.0 should tightly cooperate with application services and adaptive contents. Those technologies will be developed to construct the ubiquitous content service platform considering the evolution of networks and various converged services.

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.

This study deals with the regulatory policy of government on the convergence of broadcasting and telecommunication by applying rent seeking theory to Internet Protocal TV (IPTV). Existing literature has mainly focused on the negative implications of rent seeking since Tullock [1967], Krueger [1974] and Buchanan [1980]. We have investigated the regulatory policy along with the progress of the convergence of broadcasting and telecommunication. Regulatory policy on broadcasting, despite its impartial intent. has created the entry barrier in the industry, resulting in high rents. Meanwhile, regulatory policy in telecommunication is more geared by the encouragement of more competitive environments, resulting in reasonably low rents in the market. Regulatory policy in the age of convergence needs to improve the efficacy of the industry and welfare, while maintaining the rent at a reasonably low level. This research has contributed to emphasizing the positive aspect of rent seeking in policy concerned with the convergence of broadcasting and telecommunication, notably IPTV.
