In this study, we analyzed consumers' choices of various broadcasting and telecommunication convergence services and time consumption for chosen services by using survey data. A multivariate probit model was used to model consumers' choices of various broadcasting and telecommunication convergence services, and an ordered probit model was used to model consumers' time consumption for chosen services. Factors affecting consumers' choices and time-consumption behavior were identified, and simulation results of market competition and substitution were obtained. Based on these results, it was found that for the time being, consumers are highly locked into existing broadcasting services and are likely to become more price-sensitive to the new broadcasting and telecommunication convergence services. Also, the ways in which individual characteristics affect choices and time consumption were found to be very diverse service by service.

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.

Under the recent trend of telecommunications and broadcasting convergence, much more various forms of new convergence broadcasting services are being introduced than ever before. Owing to the unique advantages, new convergence broadcasting services are expected to bring drastic changes to the current broadcasting service market. In this research, we attempt to examine what kind of attributes critically affect the competition among new convergence broadcasting services, and how much competitive they will be, based on the quantitative information about consumer preferences for the important attributes of new convergence broadcasting services. Conjoint survey was used in order to obtain stated preference data of consumers. From the results, some implications are obtained as follows. First, even though new convergence broadcasting services have many unique advantages, still price is the most important for the consumers. Second, it is expected that considerable consumer valuation exists for the unique advantages of new convergence broadcasting services like mobility and dual-way interactivity, which will add the competitiveness of those services in the future. Third, since midterm advertising puts negative utility on consumers, broadcasting services with midterm advertising will not be preferred to those with neither advertising nor midterm advertising. Fourth, service coverage and the number of consumers using the same broadcasting service have a significant feedback effect on the competition between broadcasting services from the dynamic aspect. Lastly, the consumer preference can be affected by demographic variables like age and gender, and broadcasting service usage patterns such as channel switchover for escaping advertisement and frequency of using other recorded media. Main findings of our research might become useful information for both telecommunication and broadcasting companies, contents providers, advertisers, and policy and regulation makers to cope with the uncertain environment of telecommunication and broadcasting convergence.

Broadcasting telecommunication convergence service means a service where broadcasting and telecommunication converge. Recently with the advancement of technology, broadcasting telecommunication convergence service has been evolving to provide multimedia contents through various devices including wired and wireless network environment. Up to now, IPTV and smartphone-based convergence services have been dominant, but more developed and evolved technology and media will appear in the future. In order to derive the next generation broadcasting telecommunication convergence service supporting model, this study derives an evaluation model of broadcasting telecommunication convergence service and presents a case of evaluation of 30 demonstration projects supported by the Korean government from 2010 to 2014. In this study, we derive an evaluation model and evaluate the demonstration projects by reflecting the position of the main stake holders of service such as users, experts, and related organizational institutions, away from the existing simple service evaluation method. Expert questionnaire used AHP (Analytic Hierarchy Process) method, and the evaluation results were divided into upper and lower groups to provide key implications by a gap analysis. From this analysis this study suggests guidelines for next generation broadcasting telecommunication service support projects. The next generation broadcasting convergence service business should be based on open platform type in terms of service type. In terms of service media, it should be centered on open devices such as smart phones and smart TVs. In terms of types of business responsibilities, it should be led by public organizations and it is necessary to increase the fund matching ratio by at least 62% when the private sector participates.

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.

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.

방송 통신의 융합이 진전됨에 따라, 방송과 통신이 분리되어 규제되는 현재의 법과 제도는 상당한 문제점을 일으키고 있다. 통신망과 방송망 허가의 실질적인 권한이 규제 기관별로 분리되어 있기 때문에 통신망과 방송망의 융합에 따른 이중규제의 문제뿐만 아니라 새롭게 탄생하고 있는 신규 융합서비스를 어떠한 서비스로 분류할 것인가에 대한 논란도 제기되고 있다. 따라서 원활한 방송 통신의 융합을 촉진시키고 기존의 방송과 통신 산업의 지속적인 발전을 도모하기 위하여 방송과 통신에 대한 합리적인 규제 차등화 기준과 방송과 통신의 중간영역에 위치한 서비스들에 대한 새로운 규제환경이 필요하다. 그러나 아직 방송과 통신의 융합에 적절히 대응하기 위한 사회적 합의는 이루어지지 않은 것으로 보인다. 비록 2004년 3월에 새로운 방송법이 통과되었지만, 통과된 방송법을 살펴보면 방송과 통신의 개념에 대한 논리적인 기준을 적용하기보다는 두 기관의 이익을 어느 정도 충족시킨 미봉책에 불과하다고 결론지을 수밖에 없다. 이는 새로운 유형의 서비스가 도입되었을 때, 정보통신부와 방송위원회가 또다시 소모적인 논쟁을 되풀이할 수밖에 없음을 의미하고, 이는 통신방송 융합서비스에 대한 논쟁이 여전히 일종의 '규제의 아노미 상태'에서 벗어나지 못하고 있음을 암시한다. 따라서 본 연구는 방송과 통신의 융합 환경 속에서 전통적인 방송과 통신의 개념에 바탕을 둔 서비스의 분류가 어려워지고 있음을 지적하고, 환경변화에 부합하는 새로운 융합서비스의 개념을 방송과 통신 공공재적 특성과 양방향적 특성에 기반하여 이해해 보고자 한다. 특히 본 논문은 방송과 통신의 융합현상에 대한 '논의의 정체'를 극복하기 위한 대안으로, 기존의 논의 틀을 발전적으로 해체하고, 이를 서비스의 본질적 속성이라는 '근원적 태생'을 기준으로 재구성함으로써, 관련 규제 체제의 정비에 지침을 마련할 필요성을 의식하는 데서 시작하였다. 즉, 임기응변적인 자의적 구분을 탈피하여, 기술적 특성과 그로 인해 비롯되는 서비스의 본질적 자이를 복합적으로 고려한 융합서비스의 적정 규제 기준을 제시해보고자 하는 것이다.

최근 IT분야의 중요한 화두인 융합은 이전까지는 단순히 기술의 기능적인 융합에서 이루어져 왔다면, 최근에는 비즈니스 측면, 서비스 측면에서의 융합도 이루어지고 있다. 이러한 대표적인 유형으로서 방송통신융합은 방송산업의 디지털 전환으로 인하여 다매체, 다채널화 등과 같은 방송기술이 통신산업의 네트워크 광대역화와 융합이 가능해지면서 IPTV와 같은 융합서비스들을 출현시키게 되었다. IPTV는 방송과 통신의 융합이 본격화되면서 네트워크, 콘텐츠, 단말기의 융합이 종합적으로 결합된 새로운 서비스이다. 그럼에도 불구하고 IPTV가 인터넷TV와 무엇이 다르고 IPTV를 통해 소비자가 얻을 수 있는 편익이 무엇인지 등 새로운 융합서비스의 범위와 가치에 대해 논란이 제기되고 있다. 본 연구는 N-Screen 기반 IPTV서비스의 요구기능을 확인하기 위하여 해당 서비스에 대한 기대수준과 사용 후의 인지수준을 측정하기 위해 서비스에 대한 중요도와 만족도의 차이를 분석하고, IPA분석을 통해 각 항목별로 우선순위를 제시하였다. 이를 토대로 방송통신융합서비스 기능에 대해 제공자와 사용자 간의 인식수준 차이(Gap)를 규명하고, 사용자 만족도 제고를 위한 방안을 제시하고자 한다.

In this paper, we describe ubiquitous environments and the trend of convergence that is an evolution path of. current telecommunication, and show the concept of broadband convergence network, service feature and evolution path. In order to converge wire and wireless communication, telecommunication and broadcasting, voice and data efficiently, broadband convergence network divides a network into service layer, control layer, transport layer, ubiquitous access and terminal layer. Broadband convergence network will be a network that can provide and control broadband multimedia services with QoS and security of different and customized level. Then we depict characteristics and types of broadband multimedia service, and describe the characteristic of broadband convergence network. Finally, we show ubiquitous network based on the broadband convert- gence network to provide ubiquitous service which is a future telecommunication service. We also describe requirements of ubiquitous network such as an intelligent and context based platform, convergence terminals, ubi- quitous computing devices, etc.
