As a convergence media, IPTV is expected to provide better learning experience with customized and individualized contents. Yet, little has been known in the are of contents development. Hence, the purpose of this study was to explore educational use of IPTV in terms of design and development perspective. First, this paper identifies the concept and characteristics of IPTV in an educational context. Second, it categorizes the types of IPTV contents. Lastly, the paper discusses guidelines for the design, development, and management of educational IPTV contents.

With the advent of convergence environment of broadcasting and communication, IPTV has been widely used. It provides services such as information, movie contents and broadcasting with TV through super-highway information networks. The purpose of this study is to suggest its educational applications to overcome the limits existing in the education. For this goal, we sought its concept and characteristic and drew educational implications by analyzing its contents. We also suggested what-if scenarios for its educational applications, considered its possibilities in educational applications and suggested the kinds of teaching-learning utilizing it and its educational applications for the various subjects. Finally, we examined problems which were considered before its applications in the education with the classification of legal, technical and educational problems.

One of the most typical examples of convergence is IPTV, a convergence of broadcast and telecommunication. Demand for IPTV has been increased so rapidly that a new TV set, called a smart TV, has appeared. One of the most important factors for IPTV business success is content. If an IPTV station provides popular content and subscribers can conveniently watch it then the station has a good chance of success. Therefore, the content management module is extremely important component of IPTV systems. In the current IPTV systems, operators must be present at the office to access a Content Management System(CMS). We implement a web CMS so that the operators can access the CMS anytime and anywhere as long as they are connected to Internet.

It's been several years since IPTV(Internet Protocol Television), which is typical conversed broadcasting communication service come up to a new growth power. Although our broadcasting communication infrastructure has global competitiveness, it's been late to be commercialized rather than other countries due to lack of timely supporting policies. Also rising of smart circumstances beginning with smart phone makes smart TV grow faster, so expansibility of IPTV become shrink. This study suggests IPTV the way to get over this circumstances and the effort of government or industries.

This paper is to analyze the relative weight and the priority order of the selection factors for IPTV. To obtain the goal this paper, firstly, the selecting factors for IPTV were identified and conceptualized on reviewing previous literatures. And this paper proposed the hierarchy model using the factor analysis on IPTV users. and utilized AHP in analysis method. Secondly, AHP model constructed 4 higher factors, and 15 lower factors. The higher factors were 'Quality Acceptance', 'Social Effect', 'Using Motive' and 'Individual Psychology'. Results of this study show that relative weights among factors IPTV selection were founded as 'Quality Acceptance(33.0%)', 'Utilization Motive(31.8%)', 'Individual Psychology(21.3%)' and 'Social Influence(13.9%)'. Economic efficiency takes the top rank in sub-criteria included 15 factors and than convenience, amount of information, discrimination, self-efficacy, innovation, relative advantage in order listed. For the generalization of the research results, further researchs are needed to investigate intended use of IPTV on other method of analysis.

This research aims to examine the efficiency and effectiveness of the governmental policies promoting IPTV by verifying their influences on the adoption empirically. The government unveiled several policies including creating demands in public sectors, developing diverse public contents, subsidizing the production of converged contents, easing the regulations to promote IPTV industry. While a lot of previous literature has already proved that a system quality, a content quality, and a perceived price have influences on the adoption of IPTV, the effects of governmental policies are not well understood despite of their contributions to the adoption. Rather, most of existing research on governmental policies in the context of technology adoption have focused on regulatory frameworks. The results of the study show that governmental policies have influences on consumers' perceived system quality and content quality. It is also found that perceived system quality, content quality and perceived price have influences on adoption intention. This study can contribute to the field in a way that it proves the important roles of governmental policies in the diffusion of new technologies including IPTV.

Recently the mobile IPTV service has been spread through the wireless LAN(WLAN). In order to provide the commercial mobile IPTV service through the WLAN, re-authentication for the mobile IPTV terminal is required whenever the mobile terminal roams between APs(Access Points). The most popular one of the authentication protocol standards for the wired and/or wireless LAN is IEEE 802.1X. However IEEE 802.1X takes much time to authenticate the terminal and is not adequate for the seamless mobile IPTV service. We introduce the session key and separate the user authentication and the hardware authentication. And we strengthen the device authentication by the initial registration. By these, the proposed authentication protocol reduces the authentication time and can protect the authentication key securely.

In the near future IPTV services will be emerged the various types through Internet, but IMS based IPTV service is one of the very attractive IPTV services. This paper describes the interconnecting architectures of Web based IPTV contents provider to IMS(IP Multimedia System) network and describes the three difference architectures as method to find its IP address. One is the architecture using DNS or HSS to find IP address of Web based IPTV contents provider and connecting gateway function to I-CSCF in IMS. The other is the architecture connecting gateway AS to ISC interface of S-CSCF in IMS. This paper describes the characteristics of traffic generating due to interconnect the Web contents provider, and the traffic model of each architectures. The proposed each architecture is emulated the session establishment delay characteristics in CoD service of IPTV by the simulation. This paper shows that the architecture connecting gateway AS to ISC interface of S-CSCF is the excellent method compare to other two methods in view of the session establishment delay.

As the Korean Ministry for Health and Welfare announced the likelihood to revise the legislative limit for healthcare telemedicine, u-Healthcare service through IPTV emerged among these business models. However, in spite of many advantages such as treatment improvement, service quality enhancement, and treatment usefulness, most medical trials grafted with IT have not accepted yet. This points out not only that law and institutional environment has not prepared, but also that policy maker neglect the preparation of the strategies through the study on user acceptance. The purpose of this study is to verify the relationship for IPTV quality based Healthcare on satisfaction and intention to use. The results identify that IPTV technology quality for its convenience, contents quality for its completeness, and the quality for healthcare services give significant effect to satisfaction. In addition the study indicates that overall qualities of IPTV technology, contents, and healthcare service, significantly impact on satisfaction respectively and that the satisfaction may lead to the intention to use of this service.

네트워크 및 전송기술의 발달로 통신망을 이용하여 IPTV와 같은 서비스를 제공하는 것이 가능하게 되었다. IPTV는 기존 방송과 달리 IP 망을 통해 데이터의 송수신이 이루어지므로, 전송에러가 발생할 수 있으며, 이 경우 패킷의 손실 및 지연 등의 이유로 열화가 발생하게 된다. 이러한 열화는 사용자의 체감품질에 영향을 미쳐 IPTV서비스에 대한 사용자의 신뢰도를 저하 시킨다. 본 논문에서는 IPTV서비스에서 체감 품질 보장 및 품질 모니터링에 관한 IPTV국제 표준화 동향 및 규정을 소개하고, IPTV 사용자의 체감품질을 보장하기 위한 방법을 고찰한다.
