  • Mobile IPTV is a IPTV interactive broadcasting service through wireless Internet. Mobile IPTV service would be much more promoted. Thus, the methods for protecting the broadcasting contents will be indispensible elements for the successful Mobile IPTV service achievement. This paper describes the characteristics of Mobile IPTV and the related contents protection techniques. To evaluate several security issues, we suggest a DCAS security framework model for Mobile IPTV, and speculate the most widespread, a security technologies for Mobile IPTV such as DCSA. Moreover, candidate models of Mobile IPTV protection system are suggested based on these technologies.

  • At the most recent, IPTV service is increasing, which isa communicative broadcasting fusion service that provides various multimedia contents interactively followed by user's request through super high-speed internet. For IPTV user service with high mobility, IPTV user's enrollment is essential. However, IPTV service provided to mobile users can't provide the certification of mobile user securely. This paper proposes light user certification protocol which can certificate mobile users by attaching RFID to IPTV STB for secure awareness of mobile users who get IPTV service. The proposed protocol prevent reply attack and man-in-the-middle attack from happening oftenin a wireless section by transmitting the result value hashed by hash function with both its' ID and random number received from tag after tag transmits random number which generated randomly in the process of certification of mobile user to IPTV STB.

  • The P2P IPTV will create a new paradigm for the Internet services. However, it cannot guarantee the reliability of their server and QoS because of using common Internet users(peers) for SIP server or relay server, though the infrastructural cost is low. This paper proposes the ISP-based P2P IPTV architecture which can solute the limitations of conventional P2P-based IPTV. In this model, ISP can build P2P overlay network with ISP servers and directly manage each server needed for session connection. So, the servers have higher performance and better reliability than previous one. Besides, robustness is improved because each sever is set by P2P overlay network. To evaluate the characteristics of the ISP-based P2P IPTV architecture, we simulate it for some parameters which are end-to-end streaming delay time, connection delay time and traffic amount. We compared the proposed architecture with the conventional P2P architecture about video service and confirmed that the performance of ISP-based P2P IPTV is better than conventional P2P based IPTV.

  • IPTV, which is convergence of Communication and Broadcasting, has improved quickly recently. This service can provide high quality and various services to their customers, such as choosing channels freely, VOD and many kinds of Interactive service. As the technology of IPTV rapid development, more and more people worry about its disadvantages during the spread and apply, for instance, the illegal application, illegal copy, access authority abuse and the danger of the IPTV contents. This paper will provide the solution to solve these problems, through the Public Key Certificate of PKI(Public Key Infrastructure) and the Attribute Certificate of PMI(Privilege Management Infrastructure).

  • Since the specifications of public services in broadcasting-telecommunication convergence environment are not standardized, the public services should be developed and presented by each IPTV service provider, and therefore it is worried that public organizations and IPTV service providers may invest in the public services redundantly, which are managed inefficiently. To resolve those problem, in this paper, the service and network interfaces among multiple public organizations and multiple IPTV service providers and the interactive VOD-type public service providing system of one source multi-use based on ACAP-J are proposed. The proposed system can be utilized in the standard platform of the evolved new public services. And the used technologies can be utilized as a guide for the development of new services.

  • Recently IPTV that transmits multimedia contents in real time through internet, cable TV net and satelite net gets the limelight. But IPTV service that gives service to users by various media has a problem of not supporting user certification fully. This paper suggests a certification model which prevents getting access permission of IPTV service by sending illegal certification information by adolescent through integrating mobile communication technique with RFID(Radio Frequency IDentification) technique which is a key technique of Ubiquitous environment. This model performs the process of adult certification by keeping synchronization with user's certificaiton information that is saved in data-base of certification server and contents server after getting the system of class categorization in contents server to overcome disadvantage of simple adult certification system that is popular in the existing internet. Also, it adapts double hash chain technique not to down load illegally contents without the permission of manager even if an adolescent gets manager's approval key.

  • The multimedia contents are diffused rapidly. Also, the course individual service of communication and broadcasting coexists with each other and develop to the integrated fusion service with development of the high speed broadband IP network technology. The IPTV which is representative broadcasting a communication total service is the powerful application field. The communication industry has been interested in data processing of the high-definition that supports many kinds of internet service by internet protocol. In this paper, we configure the standard routing protocol use in the small scaled, on RIP environment and the link status routing protocol use the large scale autonomous network, on OSPF environment. We also measure and evaluate broadcasting quality by PSNR(Peak Signal-to-Noise Ratio). Finally, we propose the network construction plan for IPTV services which are efficient.

  • IPTV 서비스는 인터넷 기반의 TV서비스를 말하는 것으로, 부가서비스로서 온라인게임, 전자상거래, 인터넷 전화를 제공하는 융복합형 신규 서비스이다. 인터넷 환경에서 TV를 서비스를 제공하기 위한 관련 표준화가 ITU-T IPTV-GSI에서 활발히 이루어지고 있으며, 보안 분야에서는 IPTV 보안 요구사항, 안전한 트랜스코더블 기법, IPTV에서의 키관리 기법 등의 표준화가 진행 중에 있다. 또한 IPTV 서비스에서의 실시간 방송을 위한 주요 핵심 통신기술인 멀티캐스트에 대한 보안 기술 표준화 또한 진행중에 있다. 중계 기반 멀티캐스트 전송 규격인 X.603.1이 2007년 2월에 표준으로 제정되었고, 이에 대한 보안 규격으로서 현재 ‘중계기반 멀티캐스트 보안 규격’이 ISO/IEC와 공동으로 표준화가 진행 중이며, ‘멀티캐스트 보안 요구사항 및 프레임워크’가 ITU-T SG17/Q9 응용서비스 보안분과에서 진행 중에 있다. 멀티캐스트 보안 관련 기술 표준화는 2010년 경에 완료될 것으로 보이며, 표준제정시 IPTV에서 전송기술로 X.603.1을 사용시 보안규격으로서 적용될 것으로 전망된다.

  • The broadband access network is a worldwide trend and the related IPTV service is booming. However, the IPTV deployment has been delayed in Korea because of the business relationship between the communication and broadcasting area and the lack of the related laws. As a means to the development of FTTH-based high-quality service platform and next-generation equipment, ETRI has been building own FTTH service center with a network operation center and IPTV service equipments, also connecting it with commercial FTTH infrastructures made by network operators. In this paper, we describe the related technologies about FTTH-based IPTV testbed.
