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.

The MICE(Meeting, Incentive travel, Convention, and Exhibition) industry grows steadily. Especially, exhibition industry plays an important role as the effective sales and marketing tools. However, lots of studies have focused on the flow analysis of audience traffic, booth recommendation or formulaic interactions between audiences and contents in the exhibition hall. In this study, we proposed an intelligent Interactive system considering audience's response for providing personalized exhibition service. First, we extracted components of the system architecture through the previous studies. Second, we suggested the system architecture and scenarios for intelligent interactions between audiences and contents. We hope that the proposed system will strengthen the basis for implementing interactive system in the exhibition industry.

Recent IPTV services still remain as simple broadcasting services that cannot make the most of interactive features together with various content-associated data. So, IPTV providers are making efforts to break from monopolistic style, so as increasing the user's participation m service. However there is an interoperability problem because no common solution is employed across different providers. To solve this problem, there needs to be a framework for a framework for generating, sharing and distributing package contents. In this paper, we propose user-centered package contents application framework for interactive IPTV services. We also design a package content authoring and consuming system which plays core parts in the proposed framework.

As there are needs to search the Web information via wire or wireless telephones, VoiceXML forum was established to develop and promote the Voice eXtensible Markup Language (VoiceXML). VoiceXML simplifies the creation of personalized interactive voice response services on the Web, and allows voice and phone access to information on Web sites, call center databases. Also, it can utilize the Web-based technologies, such as CGI(Common Gateway Interface) scripts. In this paper, we have developed the voice portal service platform based on VoiceXML called TeleGateway. It enables integration of voice services with data services using the Automatic Speech Recognition (ASR) and Text-To-Speech (TTS) engines. Also, we have showed the various services on voice portal services.

As the ubiquitous technology has been widespread, the u-service development driven by the private sector is increasing these days. In this paper, a new development methodology of interactive u-services for a mixed-use complex in u-City is proposed. The current state-of-the-art IT, Web2.0, assumes that information must be communicated in both way, not only from service provides to users but also from users to service providers. Here the user-driven u-service will be utilized for service providers to customize user services. By this interactive u-service paradigm, the information users become the information providers so that the mixed-use complex will take advantage of massive information. Also, admitting that the mixed-use complex is limited in terms of the space size, the network effect of information and shared contents created through the interactive u-services can be maximized.

With the evolution of Internet technologies and the increasing variety of Internet devices, advertisements in various web services have also expanded. Interactive web services often go hand in hand with effective advertisements for a business model. We estimated statistical parameters of the interactive web server for service monitoring and advertisement-effect. In the web pages, we integrated the plugins of social networking services (SNSs) (e.g. Facebook, Twitter) and an advertisement scheme (e.g. Google AdSense) that regards social name-directory contents. Empirical data analysis and statistical results are presented with the implementation of estimations of parameters (e.g. utilization-level and serviceability) and advertisements in a social networking name-directory service (http://ktrip.net or http://한국.net). We found that estimated parameters were applicable to service monitoring of web-server as well as to synthesis of advertisement-effect in our social-web name-directory service.

High-speed network resources and large storage devices on video servers are necessary to Provide interactive VOD services to subscribers, therefore, building networks for VOD services requires a huge amount of cost. A number of studies on network hierarchy for distributed tree architecture, on optimized server allocation with a given network topology, and on program caching etc, are currently in progress. In this study, given specific network resources, a cost effective network architecture including the optimal number of tree levels and the optimal number of branches at a node are designed by modeling cost functions, and some restrictions on network design are discussed. The results of this study are expected to be applied to network architecture design for interactive VOD services

Recently "DMB Video-Associated Stereoscopic Data Services" standard has been published by TTA. The standard enables DMB broadcasters to provide 3D or stereoscopic interactive data services based on MPEG-4 BIFS (Binary Format for Scenes). The purpose is to entice viewers to utilize DMB interactive data services more often by providing realistic and protrusive image objects overlaid on top of the main video in the background. This paper provides the background, technical analysis, and in-depth considerations for the standard. Also the results of standard verification are provided including the results of interoperability test with the existing terrestrial DMB receivers.

This paper describes a digital video recorder-based approach to realising interactive programmes on digital television. So far, it is very difficult that the most interactive programmes included the vast quantities of the content, whatever it is data or HD-ready broadcasting, are broadcasted on digital television via the set-top box. Furthermore it is not possible to envisage until IPTV was appeared. Even though IPTV makes possible for streaming the interactive services via broadband, it is not easy to receive tremendous contents for interactivity as set-top box at once. In this paper it will suggest an effective solution to resolve the download dilemma for the interactive services on DTV by employing the set-top box fitted with digital video recorder.
