ECC-based IPTV Service Key Establishment Protocol With User Attribute

The Internet protocol television (IPTV) service enables people to enjoy various Internet-based services via conventional TV watching. In the IPTV system, a set-top box (STB) is the key since it works as a terminal device that can relay real-time multimedia content from the Internet. However, the current IPTV STB functions as an attached device in a local area network although the actual IPTV network is usually served by an optical fiber-based network such as fiber-to-the-home (FTTH). Therefore, we introduce a novel fiber channel (FC)-embedded IPTV STB to fully use the sufficient optical fiber-based network bandwidth such as 1 Gbps. To verify the IPTV network capabilities by impact of the FC-embedded STB, we evaluate the performance of the FC-embedded STB-attached IPTV network architecture via extensible simulations in terms of an average startup-delay, an average reject ratio, and the number of concurrent users. Surprisingly, the suggested IPTV system demonstrates superior average startup-delay (less than 15 msec), an acceptable average reject-ratio less than 3%, and an almost linear increasing number of concurrent users, which reveals that the FC-embedded STB significantly affects the entire FC-AL-based IPTV network performance by efficiently facilitating the broadband optical fiber bandwidth.

Openness has been added to IPTV (Internet Protocol Television) services in order for users not only to receive, but also to provide them. Open IPTV is expected to bring about great changes in the IPTV service area. Recently, mobility has also been added. However, because of its openness and IP network characteristics, security is one of the major issues hindering its commercialization. For IPTV, several security mechanisms for user authentication and content protection have been proposed to make the service reliable. However, these traditional security mechanisms cannot be adopted in the mobile IPTV area, because the security and system performance are influenced by numerous factors in the many-to-many environments. In our work, we propose a mechanism for secure user authentication and key distribution based on Kerberos for mobile open IPTV. Our proposal provides an efficient authentication process and the secure transmission of content among users, and further decreases the authentication time compared w...

In this paper, we propose the effective playback scheme of targeted AD (ADvertisement) contents exploiting digital cueing signal over IPTV (Internet Protocol TeleVision) service. In the proposed scheme, the digital cueing signal multiplexed with the watching live IPTV program contents enables a STB (Set-Top Box) device to identify AD playback section accurately. For eliminating playback delay of pre-downloaded AD contents during AD playback section, a STB device then adjusts their MPEG (Moving Picture Experts Group)-2 TS (Transport Stream) attributes of pre-downloaded AD contents. Test results demonstrate that the proposed scheme works greatly over commercial IPTV network.

Vehicular Networks represent one of the main topics in the communication systems area. Increased deployment of vehicular networks together with new possibilities for Internet Protocol Television (IPTV) services has spurred the interest in providing mobile IPTV via vehicular networks. Provisioning of IPTV services over vehicular networks can be expected to play a significant role in the next generation of TV systems. Users will choose IPTV based on the Quality of Experience (QoE). Among QoE measures, TV channel availability is one of the most significant. In this paper, we investigate the channel availability in IPTV services with different traffic intensity and a varying number of TV channels offered to find out the acceptable availability of TV channels or the Call Blocking Probability (CBP) in our study. Comprehensive experiments are carried out by means of our own simulation tool, i.e., a Monte Carlo simulator to conduct the evaluations for numerous scenarios taking into account realistic IPTV user behavior.

Current advances in embedded hardware for mobile devices, jointly with new type of batteries that let smart phones have more power during longer periods of time, allow them to offer new services to customers. Internet Protocol Television (IPTV) is the Internet Protocol (IP) service that is experiencing highest demand. Many mobile telephone companies are adding this service to their supply. In this chapter, the authors show all steps to transmit the IPTV service from the provider to the smart phone. First, they introduce the current hardware and operating systems for smart phones. Then, they describe the main parts of the IPTV architecture and the main protocols used for IPTV transmission in order to show how it works. Next, the authors show where intelligent systems can be deployed in the IPTV network in order to provide better QoE (Quality of Experience) on the end-user side. Then, they discuss the limitations and requirements for IPTV reception on smart phones. Finally, the authors explain the IPTV implementation in smart phones and describe an IPTV player on Android.

Internet Protocol Television (IPTV) is a service to present digital TV over Internet. The IPTV network architecture consists of two main components: core network and access network. Many types of access networks can be used for IPTV including Ethernet PON (EPON). In this paper, a new mechanism is proposed for bandwidth allocation to various IPTV services over the EPON that decreases IPTV packet loss. This mechanism is implemented in optical line terminal (OLT) and weights are allotted to queues in the OLT to reduce packet loss. Then, weighted round robin (WRR) is used to scheduling IPTV packets.

In digital television (DTV) broadcasting, service providers charge a subscribing fee by scrambling the program with conditional access system as well as control the illegal receiving of the charged program. A smart card is used to decrypt the control words and transfer them back to set-top box (STB) to descramble the scrambled program. Secure communication between STB and smart card is directly related with the benefit of service providers and the legal rights of users, while key exchange is the essential part of secure communication. In this paper, we propose a key exchange protocol for STB and smart card based on Schnorr's digital signature protocol and one-way hash function. Our proposed protocol is dynamic, secure, mutual authenticated and lower computation. Moreover, the proposed protocol can prevent smart cloning and McCormac Hack problems.

As the speed of networks that subscribers can use has greatly increased, demand for high-quality broadcast content, such as from Internet Protocol Television (IPTV) and Video on Demand (VoD), is likewise increasing. Therefore, while broadcasters are increasing content and channels, they are striving to improve consumer quality of experience (QoE) to differentiate themselves from competitors, including by producing higher physical-quality content. Recently, subjective measurement methods have been internationally standardized as the most reliable approach for measuring and evaluating IPTV QoE. However, a majority of these methods are performed in experimental environments and are based on the extremely brief viewing period of approximately ten seconds using original reference videos. It is actually difficult to apply standard evaluation methods based on a ten-second viewing interval to assess real broadcast watching of IPTV or other services that involve a longer time (i.e., more than thirty minutes). In this paper, we therefore propose a method that accommodates actual viewing environments. Using the mean opinion score, we experimentally analyze the effects of evaluation interval changes under actual conditions in which IPTV service is provided. In addition, we propose improvements by applying the results into actual live broadcast IPTV service and by analyzing consumer service QoE.

Internet Protocol Television (IPTV) provides an interactive and personalized service for realizing integrated broadcasting and telecommunication services. Set-top box (SIB) connected to TV is an essential component required for IPTV and has a unique hardware identifier used in identification and authentication. It means that subscriber authentication based on box-level identification is inconsistent with IPTV`s main intention of providing personalized services. The proposed solution is to provide an opportunity to use the flexible user-centric authentication mechanism through Java Card applets in IPTV application server and 3G networks. This paper suggests personalized services by moving the user`s private data and authentication management beyond the STB to a truly personalized device, the ubiquitous mobile phone. In addition, this paper presents effectiveness and security analysis for verifying the proposal.

Internet Protocol Television (IPTV) is a service where digital TV signal data is delivered by using Internet protocol (IP). Telecom and network operators focus on IPTV service for its fastest growth, lower price for operators and market economy. With the improvement of broadband connection and technology, IPTV will get more and more importance. Main challenge for IPTV service is resiliency and Quality of Service (QoS) to meet the users Service Level Agreement (SLA). The design space for IPTV service in terms of resilient backbone design, routing algorithms and fast failure restoration shall be explored. It is described from DSL FORUM and leading IPTV service-providing companies. In the context of this work, the PIM-SSM was configured and QoS was implemented for tagged VLAN of multicast traffic. IPTV traffic is analysed in ACREO testbed and Norrksen network.Keywords: IPTV; QoS; Multicast; PIM; PIM-SM; PIM-SSM; VLAN.© 2009 JSR Publications. ISSN: 2070-0237 (Print); 2070-0245 (Online).

In this paper, we propose an effective packet loss recovery scheme using a cache server in IPTV (Internet Protocol TeleVision) multicast service. In the proposed scheme, the cache server detects which packets have been lost by using the additional information received from STB (Set-Top Box) device. And then, it retransmits these lost packets to STB device. Test results shows the high recovery success rate of the proposed scheme for packet losses over the commercial IPTV network.

To provide secure delivery of satellite data in IPTV systems, service providers charge subscribing fee by scrambling the program in conditional access system using control words. At the receiver end, smart card is used to decrypt the control words and transfer them back to set-top box to descramble the scrambled program. Therefore, secure communication between set-top box and smart card is closely related with the benefit of service providers and the legal rights of users. In this paper, we propose secure mutual authentication and key agreement protocol between set-top box and smart card in IPTV broadcasting. The proposed scheme is more efficient than any other previously proposed schemes by eliminating exponentiation operations which are time-consuming. Moreover, our scheme can prevent two common serious problems - smart card cloning and McCormac Hack problems - in IPTV broadcasting.

In 2005, Yoon et al. proposed a user-friendly remote user authentication scheme using smart cards. The security of their scheme is based on one-way hash function and they claimed that their scheme is secured from attacks and achievable for proving mutual authentication, freely choosing password, no verification tables, and involving very lightweight hashing operations. However, we find that Yoon et al.'s scheme suffers from the denial of service attack and performs only unilateral authentication (only user authentication). In this paper we consequently propose an enhanced version to eliminate the vulnerability. Furthermore, our enhanced scheme can also provide mutual authentication and key agreement between a remote server and login users.

This letter proposes a weighted scheduling mechanism for Internet protocol television (IPTV) to improve the loss performance of multicast transmission over an Ethernet passive optical network (EPON). We propose a new weight policy from the number of multicast receivers to proportionally allocate the downstream bandwidth of IPTV traffic. The proposed mechanism is used in an optical line terminal to decrease lost packets of favorite IPTV services because the lost multicast packets are proportional to the number of receivers. The total proportion of lost multicast packets is reduced by up to 73% in an EPON.
