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.

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.

In this paper, we present an interactive data broadcasting system compliant with the Advanced Television Systems Committee (ATSC) standards. The proposed system provides users not only with various data broadcasting services but also remote interactive services. For various data broadcasting services, we have adopted a synchronized data injector that calculates the transmission time of synchronized data accurately and multiplexes synchronized data with the data of an MPEG-2 audio-visual program according to the calculated transmission time. To support remote interactive services, we designed and implemented a return channel server connected on a bi-directional interaction channel. Test results show that the proposed system provides both an asynchronous and synchronized data broadcasting service and remote interactive service appropriately.

DMB data broadcasting has recently come into the spotlight as a platform for a new business opportunity and an application of various contents. This paper estimates the willingness to pay for the DMB data broadcasting services and explains the demand characteristics for TPEG, BIFS and BWS services, using the Double-bounded dichotomous choice Contingent Valuation Method. Consumers are willing to pay 2,039 Korean won for TPEG service and 1,612 Korean won for BIFS and BWS services per month, which corresponds to the market size 87.6 billion Korean won for TPEG and 195.2 billion Korean won for BWS and BIFS a year respectively. It is also found that the more consumers show usage intentions, have experiences in the similar services, and know of the DMB data broadcasting services, the more they are likely to pay for the DMB data broadcasting services.

In recent years, many users preferred video records, and as the broadcasting video data becomes necessary, the demand for video records' use has increased. However, most broadcasters' archive agencies currently provide archive services only for internal employees, and for the general public. In this study, the web-based online information services provided to the general public in the archive sites of domestic and foreign public broadcasting companies were examined and analyzed. The evaluation criteria for the web-based records information services were identified in three service areas: online accessibility, search and online browsing, and outreach or expansion services. The overseas public broadcasters' web-based services and the public broadcasting companies' current status were examined for each area. Based on the examination, direction improvements, such as providing online search and records, developing various outreach services, and expanding user levels were proposed for the information services on broadcasting video data in public broadcasting companies for the general public.

Due to the development of the digital technology, the digital broadcasting is changing to a multi-entertainment platform that can operate data (broadcasting) services (such as games, weather information, and stock trading services) as well as traditional broadcasting contents. Most of the data services, however, failed to get satisfactory results because of the inconvenience in operating the services using a TV remote controller and the failure of gaining the viewer's interests in the competition with the broadcasting contents. The paper introduces a survey on the viewer's modality of using a data service and, based on the survey result, proposes a design guideline that makes a data service minimally interrupt a viewer watching a broadcasting content.
