Chen, S., Li, S., Shyu, M., Zhan, C. & Zhang, C. A multimedia semantic model for RTSP-based multimedia presentation systems 2002 Proc. Fourth International Symposium on Multimedia Software Engineering   inproceedings DOI  
Abstract: An abstract multimedia semantic model called the multimedia augmented transition network (MATN) model is proposed to model the RTSP-based (real-time streaming protocol) multimedia presentation systems. RTSP provides a set of methods to support the functionality of "VCR-like" remote control on the client side so that users are allowed to control playback of the streaming media. The MATN model is used to model RTSP actions as well as temporal relations and synchronization control of the media streams. The advantages of using the MATN model are its simplicity, effectiveness, and ease of modification. Furthermore, a formal definition of the MATN model and modeling of RTSP actions using the MATN model are presented in detail.

Christel, M. & Conescu, R. Addressing the challenge of visual information access from digital image and video libraries 2005 Proc. 5th ACM/IEEE-CS Joint Conference on Digital Libraries JCDL '05   inproceedings DOI  
Abstract: While it would seem that digital video libraries should benefit from access mechanisms directed to their visual contents, years of TREC Video Retrieval Evaluation (TRECVID) research have shown that text search against transcript narrative text provides almost all the retrieval capability, even with visually oriented generic topics. A within-subjects study involving 24 novice participants on TRECVID 2004 tasks again confirms this result. The study shows that satisfaction is greater and performance is significantly better on specific and generic information retrieval tasks from news broadcasts when transcripts are available for search. Additional runs with 7 expert users reveal different novice and expert interaction patterns with the video library interface, helping explain the novices' lack of success with image search and visual feature browsing for visual information needs. Analysis of TRECVID visual features well suited for particular tasks provides additional insights into the role of automated feature classification for digital image and video libraries.

Dao, S., Shek, E., Vellaikal, A., Muntz, R. R., Zhang, L., Potkonjak, M. & Wolfson, O. Semantic multicast: intelligently sharing collaborative sessions 1999 ACM Comput. Surv.   article DOI  
Abstract: We introduce the concept of semantic multicast to implement a large-scale shared interaction infrastructure providing mechanisms for collecting, indexing, and disseminating the information produced in collaborative sessions. This infrastructure captures the interactions between users (as video, text, audio and other data streams) and promotes a philosophy of filtering, archiving, and correlating collaborative sessions in user and context sensitive groupings. The semantic multicast service efficiently disseminates relevant information to every user engaged in the collaborative session, making the aggregated streams of the collaborative session available to the correct users at the right amount of detail. This contextual focus is accomplished by introducing proxy servers to gather, annotate, and filter the streams appropriate for specific interest groups. Users are subscribed to appropriate proxies, based on their profiles, and the collaborative session becomes a multi-level multicast of data from sources through proxies and to user interest groups.

Declerck, T., Wittenburg, P. & Cunningham, H. The automatic generation of formal annotations in a multimedia indexing and searching environment 2001 Proceedings of the workshop on Human Language Technology and Knowledge Management   inproceedings DOI  
Abstract: We describe in this paper the MU-MIS Project (Multimedia Indexing and Searching Environment), which is concerned with the development and integration of base technologies, demonstrated within a laboratory prototype, to support automated multimedia indexing and to facilitate search and retrieval from multimedia databases. We stress the role linguistically motivated annotations, coupled with domain-specific information, can play within this environment. The project will demonstrate that innovative technology components can operate on multilingual, multisource, and multimedia information and create a meaningful and queryable database.

Friedrich, O., Seeliger, R. & Arbanowski, S. Interactive and Personalized Services for an Open IMS-Based IPTV Infrastructure 2008 Proc. Seventh International Conference on Networking ICN 2008   inproceedings DOI  
Abstract: In this paper a proof of concept infrastructure for the delivery of IMS-based IPTV services driven by the IPTV enabled FOKUS Open IMS infrastructure will be presented. As the different Standard Development Organizations (SDOs) will release frameworks for standardized IPTV by the end of this year the FOKUS Media Interoperability Lab (MIL) represents one of the world’s first real world test beds for these kind of services. This has been achieved by actively guiding the different SDOs work with a focus on ETSI TISPAN. On top of this framework different personalized and interactive services have been implemented to show the predominance and advantages of IMS-based IPTV solutions compared to other mainly black box approaches.

Garcia, M. N., Raake, A. & List, P. Towards content-related features for parametric video quality prediction of IPTV services 2008 Proc. IEEE International Conference on Acoustics, Speech and Signal Processing ICASSP 2008   inproceedings DOI  
Abstract: This paper investigates video content-related features, such as measures of spatio-temporal complexity, for inclusion into parametric video quality models. Our goal is to find a parametric content description that correlates with perceived video quality. In the course of the development of a parametric IPTV video quality prediction model (T-V-model), a large number of subjective tests have been conducted for standard definition and high definition video with different types of content. As expected from previous studies, we observed content dependencies that were different for different types of degradations. As descriptors of the content, we employ spatio-temporal related information obtained either before encoding and from the decoder or obtained from the decoder only. We compare those two approaches and explore their application to a reduced- or no-reference parametric model. An outlook highlights future steps for integrating the spatio- temporal features into the parametric model.

Guo, Y., Lin, C., Yin, H. & Zhao, Z. Design and analysis of IPTV digital copyright management security protocol 2007 Proc. International Symposium on Intelligent Signal Processing and Communication Systems ISPACS 2007   inproceedings DOI  
Abstract: On the basis of analysis of various streaming media digital copyright management security protocols, this paper presents a digital copyright protection protocol which is adaptive to dynamic, distributed and heterogeneous IPTV network environments and can span the diverse security domain. This protocol does not only meet the basic requirements of digital copyright protection, but also has the ability to defend against IPTV protocol attacks and assure fairness between digital content Web service providers and customers by introducing a gateway web service and copyright center. We also apply WS-Security to the protocol to ensure end-to-end security and wsdl which explains how operations can be invoked. Furthermore, a formalization tool is applied to analyze the security of the protocol and the analysis results indicate that the protocol is secure.

Abstract: As current methods for content-based retrieval are incapable of capturing the semantics of images, we experiment with using spectral methods to infer a semantic space from user's relevance feedback, so the system will gradually improve its retrieval performance through accumulated user interactions. In addition to the long-term learning process, we also model the traditional approaches to query refinement using relevance feedback as a short-term learning process. The proposed short- and long-term learning frameworks have been integrated into an image retrieval system. Experimental results on a large collection of images have shown the effectiveness and robustness of our proposed algorithms.

Hei, X., Liang, C., Liang, J., Liu, Y. & Ross, K. A Measurement Study of a Large-Scale P2P IPTV System 2007 IEEE Transactions on Multimedia   article DOI  
Abstract: An emerging Internet application, IPTV, has the potential to flood Internet access and backbone ISPs with massive amounts of new traffic. Although many architectures are possible for IPTV video distribution, several mesh-pull P2P architectures have been successfully deployed on the Internet. In order to gain insights into mesh-pull P2P IPTV systems and the traffic loads they place on ISPs, we have undertaken an in-depth measurement study of one of the most popular IPTV systems, namely, PPLive. We have developed a dedicated PPLive crawler, which enables us to study the global characteristics of the mesh-pull PPLive system. We have also collected extensive packet traces for various different measurement scenarios, including both campus access networks and residential access networks. The measurement results obtained through these platforms bring important insights into P2P IPTV systems. Specifically, our results show the following. 1) P2P IPTV users have the similar viewing behaviors as regular TV users. 2) During its session, a peer exchanges video data dynamically with a large number of peers. 3) A small set of super peers act as video proxy and contribute significantly to video data uploading. 4) Users in the measured P2P IPTV system still suffer from long start-up delays and playback lags, ranging from several seconds to a couple of minutes. Insights obtained in this study will be valuable for the development and deployment of future P2P IPTV systems.

Hei, X., Liu, Y. & Ross, K. IPTV over P2P streaming networks: the mesh-pull approach 2008 IEEE Communications Magazine   article DOI  
Abstract: IPTV, an emerging Internet application, would revolutionize the entertainment and media industries; however, IPTV also has the potential to overwhelm the Internet backbone and access networks with traffic. To date, IPTV over P2P streaming networks has advanced significantly using two different approaches: tree-push versus mesh-pull. In particular, the mesh-pull streaming approach has achieved a number of successful commercial deployments. In this article, we examine the current progress in the research and development of mesh-pull P2P streaming systems. We provide an overview of the general mesh-pull streaming architecture and review various challenges, design issues, and interesting research problems in this approach. We discuss the construction costs for providing an IPTV service with service guarantees. We outline a measurement technique for monitoring the video playback quality of mesh-pull streaming systems. We emphasize that the future P2P IPTV systems should be designed to meet the expectations of users for quality-of-experience. We also identify a few other important issues for IPTV over P2P streaming networks, including the traffic pressure on ISPs, various security concerns, and the necessity to re-examine the most appropriate P2P architecture. Insights obtained in this study will be valuable for the development and deployment of future P2P IPTV systems.

Abstract: This paper studies the conditions under which P2P sharing can increase the capacity of IPTV services over FTTN networks. For a typical FTTN network, our study shows a) P2P sharing is not beneficial when the total traffic in a local video office is low; b) P2P sharing increases the load on FTTN switches and routers in local video offices; c) P2P sharing is the most beneficial when the network bottleneck is experienced in the southbound segment of a local video office (equivalently a northbound segment of an FTTN switch); and d) sharing among all FTTN serving communities is not needed when network congestion problems are solved by using some other technologies such as program pre-caching or replication. Based on the analytical results, design for IPTV services which monitors FTTN network conditions and decides when and how to share videos among peers to maximize the service capacity. Simulations and bounds both validate the potential benefits of the MediaGrid IPTV service platform

Joo, H., Song, H., Lee, D. & Lee, I. An Effective IPTV Channel Control Algorithm Considering Channel Zapping Time and Network Utilization 2008 IEEE Transactions on Broadcasting   article DOI  
Abstract: This paper presents a simple but effective IPTV channel control algorithm that keeps channel zapping time in the tolerable range with high network utilization. The proposed algorithm controls channel zapping time by adjusting the number of broadcasting channels that are located close to users over IP networks and the number of additional I-frames inserted into each channel, based on the user's channel preference information. Finally, experimental results are provided to show the performance of the proposed algorithm.

Abstract: Within the NGN architecture, the resource and admission control functions (RACF) act as the arbitrator between service control functions and transport functions for QoS related transport resource control within access and core networks. The decision is based on transport subscription information, SLAs, network policy rules, service priority and transport resource status and utilization information. This paper provides a mechanism for resource control and functional architecture of overlay multicast for IPTV service in NGN.

Liu, X., Huang, T., Huo, L. & Mou, L. A DRM Architecture for Manageable P2P Based IPTV System 2007 Proc. IEEE International Conference on Multimedia and Expo   inproceedings DOI  
Abstract: With the improvement of network bandwidth, multimedia services based on streaming live media have gained much attention recently, among which IPTV has become a hot topic. After emergence of Peer-to-Peer (P2P) technology, P2P based IPTV systems are deployed widely. However, there exists a huge challenge, which is how to manage content. Digital rights management (DRM) is such a system that includes encryption and other technologies which can control the usage and redistribution of the digital contents. In this paper, we first review the related works in this area and analyze the DRM requirements. Then we propose a DRM architecture for a manageable P2P based IPTV system. In our architecture, we also present content encryption scheme and content authentication scheme.

Liu, Z., Gibbon, D. & Shahraray, B. Uninterrupted Recording and Real Time Content-Based Indexing Service for IPTV Systems 2008 Proc. 5th IEEE Consumer Communications and Networking Conference CCNC 2008   inproceedings DOI  
Abstract: Internet protocol TV (IPTV) is a system to deliver TV content to customers by using IP. It has been deployed worldwide by many IPTV service provides, including AT&T, BT, etc. In addition to the core video services provided by the traditional cable TV and satellite TV systems, IPTV provides much richer user interactions and enables additional value added services. This paper presents a prototype for such kind of service: uninterrupted recording and real time media content indexing service for IPTV platforms. While electronic program guides (EPG) list the TV programs that will be broadcast in the future and allow the users to schedule recording for shows that they are interested in, our prototype empowers the users to search and browse any moment of all recent broadcast content for certain channels. Based on the business interest and requirements, this service can be realized in either a centralized architecture (on the network side) or a distributed one (on the individual client side). The developed user interface can be seamlessly integrated on IPTV platforms, and it has been successfully demonstrated on the set top box (STB).

Liu, Z., Gibbon, D. & Shahraray, B. Multimedia content acquisition and processing in the MIRACLE system 2006 Proc. 3rd IEEE Consumer Communications and Networking Conference CCNC 2006   inproceedings  
Abstract: This paper describes the content acquisition, indexing and repurposing components of the MIRACLE system. MIRACLE is an ongoing research project at AT&T Labs aimed at creating automated content-based media processing algorithms and systems to collect, organize, index, mine, and repurpose video and multimedia information. While the retrieval engine and the user interface are the most visible part of the query process, performing the required processing to extract the relevant information and generate the indices for the retrieval engine is the most crucial and challenging component of the overall system. Moreover, the utility of the system is highly dependent on the quality and quantity of the acquired data. We discuss a scalable processing architecture for extracting information that enables efficient searching and browsing of more than 32,000 hours of video programs. We describe a new version of the

acquisition system that takes advantage of Personal Video Recorder (PVR) functionality of Windows OS to acquire high-quality video and the associated metadata.

Lopez, V., Garcia-Dorado, J., Hernandez, J. & Aracil, J. Performance comparison of scheduling algorithms for IPTV traffic over polymorphous OBS routers 2007 Proc. ICTON Mediterranean Winter Conference ICTON-MW 2007   inproceedings DOI  
Abstract: Recent research in optical burst switched networks has proposed solutions to support subwavelength reservation for the periodic transmission of data bursts, which can coexist with conventional asynchronous bursts, bringing the polymorphous, agile and transparent optical networks (PATON) [1]. Thus, network operators can distribute IPTV channels to their customers, whereby they can use the spare bandwidth for the transmission of best-effort traffic, making use of the free gaps in between such periodic reservations. This work proposes scheduling algorithms for the transmission of periodic channels using PATON, and studies the blocking probability observed by best-effort traffic, when such scheduling algorithms are used.

Lu, M., Wu, J., Peng, K., Huang, P., Yao, J. & Chen, H. Design and Evaluation of a P2P IPTV System for Heterogeneous Networks 2007 IEEE Transactions on Multimedia   article DOI  
Abstract: NTUStreaming is an overlay P2P-based IPTV system that integrates innovations in both overlay networking and video coding for optimal user experience. The system consists of three key components: partnership formation, robust video coding, and video segment request scheduling. For partnership formation, a graph construction mechanism TYPHOON based on epidemic algorithms is developed to reduce disconnect time and isolated peers. For robust video coding, a multiple description coding (MDC) scheme with spatial-temporal hybrid interpolation (STHI) is proposed to adjust streaming traffic according to the bandwidth and device capability of each peer. For request scheduling, an optimization algorithm is developed by taking the available bandwidth and the video segment type into account. Experimental results show that NTUStreaming is able to deliver optimal video quality in lossy and dynamic networking environments.

Lyu, J., Pyo, S., Lim, J., Kim, M., Lim, S. & Kim, S. Design of Open APIs for Personalized IPTV Service 2007 Proc. 9th International Conference on Advanced Communication Technology   inproceedings DOI  
Abstract: With the broadcasting and network convergences, IPTV which is a broadcasting service using IP network, becomes popular as a new business model. The IPTV service supports the user-interactive and personalized broadcasting service. However, it is difficult to serve the IPTV services to the universal user terminals in the heterogeneous network environment. In this paper, we study the service scenarios for the personalized broadcasting services under open network environments and extend the Parlay X Web service structure for the personalized EPG, NDR and target advertisement services from the service scenarios. For these three services, we specify open APIs based on Parlay X for open network environments. Based on these open network environments for the personalized broadcasting services, it is possible to provide new business model to the network operators, to reduce the duplicable investment in new business by defining the roles of each service provider and to develop the various and inventive services through the third party application service. We also implement the prototype system for open APIs based on the extended Parlay X Web service structure which are named personalized EPG, NDR and target advertisement.

Mei, T., Hua, X., Yang, L. & Li, S. VideoSense - towards effective online video advertising 2007 MULTIMEDIA '07: Proceedings of the 15th international conference on Multimedia   inproceedings DOI  
Abstract: With Internet delivery of video content surging to an unprecedented level, online video advertising is becoming increasingly pervasive. In this paper, we present a novel advertising system for online video service called VideoSense, which automatically associates the most relevant video ads with online videos and seamlessly inserts the ads at the most appropriate positions within each individual video. Unlike most current video-oriented sites that only display a video ad at the beginning or the end of a video, VideoSense aims to embed more contextually relevant ads at less intrusive positions within the video stream. Given an online video, VideoSense is able to detect a set of candidate ad insertion points based on content discontinuity and attractiveness, select a list of relevant candidate ads ranked according to global textual relevance, and compute local visual-aural relevance between each pair of insertion points and ads. To support contextually relevant and less intrusive advertising, the ads are expected to be inserted at the positions with highest discontinuity and lowest attractiveness, while the overall global and local relevance is maximized. We formulate this task as a nonlinear 0-1 integer programming problem and embed these rules as constraints. The experiments have proved the effectiveness of VideoSense for online video advertising.

Mushtaq, M. & Ahmed, T. P2P-based mobile IPTV: Challenges and opportunities 2008 Proc. IEEE/ACS International Conference on Computer Systems and Applications AICCSA 2008   inproceedings DOI  
Abstract: In the last few years, we have witnessed a rapid growth of multimedia content delivery across the networks. Peer-to-Peer (P2P) networks are considered as one of the most suitable targeted infrastructure for supporting real time streaming and has played vital role in this growth. IPTV service is considered as the emerging application that has a great potential to incur new revenues for contents and service providers. This service gives more choice to the end users to consume TV programs in their personalized way and beyond any geographical constraints. The exploitation of P2P- based IPTV services has turned the dream of Universal Media Access (UMA) in reality. However, the efficient deployment of P2P-based IPTV with better Quality of Service (QoS) needs to address certain challenges. However, for the provision of better QoS IPTV service, we need to cope with the dynamic characteristics of P2P framework that can deter drastically the performance of such applications. In this paper, we emphasize some challenges, opportunities, and open issues regarding IPTV service over mobile terminals operating over P2P based networks.

Natsev, A. (P., Naphade, M. R. & TešiĆ, J. Learning the semantics of multimedia queries and concepts from a small number of examples 2005 MULTIMEDIA '05: Proceedings of the 13th annual ACM international conference on Multimedia   inproceedings DOI  
Abstract: In this paper we unify two supposedly distinct tasks in multimedia retrieval. One task involves answering queries with a few examples. The other involves learning models for semantic concepts, also with a few examples. In our view these two tasks are identical with the only differentiation being the number of examples that are available for training. Once we adopt this unified view, we then apply identical techniques for solving both problems and evaluate the performance using the NIST TRECVID benchmark evaluation data [15]. We propose a combination hypothesis of two complementary classes of techniques, a nearest neighbor model using only positive examples and a discriminative support vector machine model using both positive and negative examples. In case of queries, where negative examples are rarely provided to seed the search, we create pseudo-negative samples. We then combine the ranked lists generated by evaluating the test database using both methods, to create a final ranked list of retrieved multimedia items. We evaluate this approach for rare concept and query topic modeling using the NIST TRECVID video corpus.In both tasks we find that applying the combination hypothesis across both modeling techniques and a variety of features results in enhanced performance over any of the baseline models, as well as in improved robustness with respect to training examples and visual features. In particular, we observe an improvement of 6% for rare concept detection and 17% for the search task.

Abstract: It is now accepted that powerful retrieval of multimedia data can be achieved with the integration of semantic and contextual metadata that relate to multimedia objects. In the case of objects related to culture and history there is a wealth of related information stored in Digital Libraries. CIDOC/CRM is a new, rapidly adopted standard in the field of cultural heritage that provides a very powerful model for encoding cultural heritage knowledge. In this paper we propose that knowledge is extracted and encoded in MPEG-7 multimedia object descriptions in an automatic manner so that the multimedia objects are augmented with very rich metadata descriptions coming from Digital Libraries. We analyze the mapping problem between CIDOC/CRM and MPEG-7 and we present the algorithms and a software system that supports this mapping.

Ortiz, S., J. Phone Companies Get into the TV Business 2006 Computer   article DOI  
Abstract: Competition in the telecommunications industry has become fierce in the past few years, and phone companies have increasingly found themselves on the losing end. Competition from wireline, cellular, and voice over IP (VoIP) services, including those from cable TV companies, has reduced telephone carriers' customer bases, prices, and profit margins. To accomplish their goals, phone carriers are trying to provide the "triple play" of voice, video, and data services, which cable TV companies already offer. IPTV uses IP networks to deliver TV programming from a central location to a base of multiple subscribers. In addition to software that provides basic functionality, IPTV systems run middleware and both back-office and digital rights management (DRM) software

Peoples, C., Dini, P., McClean, S., Parr, G. & Black, M. Bringing IPTV to the Market through Differentiated Service Provisioning 2006 International Journal of Computers, Communications & Control   article  
Abstract: The world of telecommunications continues to provide radical technologies. Offering the benefits of a superior television experience at reduced long-term costs, IPTV is the newest offering. Deployments, however, are slow to be rolled out; the hardware and software support necessary is not uniformly available.

This paper examines the challenges in providing IPTV services and the limitations in developments to overcome these challenges. Subsequently, a proposal is made which attempts to help solve the challenge of fulfilling real-time multimedia transmissions through provisioning for differentiated services. Initial implementations in Opnet are documented, and the paper concludes with an outline of future work.

Abstract: Knowledge representation and semantic annotation of multimedia documents typically have been pursued in two different directions. Previous approaches have focused either on low-level descriptors, such as dominant colour, or on the semantic content dimension and corresponding manual annotations, such as person or vehicle. Here, a knowledge infrastructure and an experimentation platform for semantic annotation to bridge the two directions are presented. Ontologies are being extended and enriched to include low-level audiovisual features and descriptors. Additionally, a tool that allows for linking low-level MPEG-7 visual descriptions to ontologies and annotations is presented. Thus, ontologies that include prototypical instances of high-level domain concepts together with a formal specification of the corresponding visual descriptors are constructed. This infrastructure is exploited by a knowledge-assisted analysis framework that may handle problems such as segmentation, tracking, feature extraction and matching in order to classify scenes, identify and label objects and thus automatically create the associated semantic metadata.

Abstract: The number of digital lecture video recordings has increased dramatically. The accessibility, usability and the traceability of their content for students-use is limited. Therefore retrieval of audiovisual lecture recordings is a complex task. Speech recognition is applied to create a tentative and deficient transcription of the video recordings. The imperfect transcription is sufficient to generate semantic metadata serialized in an OWL file. A question answering system based on the automatically generated semantic annotations and a semantic search engine are presented. The annotation process is discussed, evaluated and compared to a perfectly annotated OWL file and, further, to a corrected transcript of the lecture.

Abstract: The number of digital video recordings has increased dramatically. The idea of recording lectures, speeches, and other academic events is not new. But, the accessibility and traceability of its content for further use is rather limited. Searching multimedia data, in particular audiovisual data, is still a challenging task to overcome. We describe and evaluate a new approach to generate asemantic annotation for multimedia resources, i.e., recorded university lectures. Speech recognition is applied to create atentative and deficient transliteration of the video recordings. We show that the imperfect transliteration is sufficient to generate semantic metadata serialized in an OWL file. The semantic annotation process based on textual material and deficient transliterations of lecture recordings are discussed and evaluated.

Abstract: In the SmartPush project professional editors add semantic metadata to information flow when the content is created. This metadata is used to filter the information flow to provide the end users with a personalized news service. Personalization and delivery process is modeled as software agents, to whom the user delegates the task of sifting through incoming information. The key components of the SmartPush architecture have been implemented, and the focus in the project is shifting towards a pilot implementation and testing the ideas in practice. Introduction Internet and online distribution are changing the rules of professional publishing. Physical constraints of media products are not any more the key factors in the publishing process. In newspaper publishing, the bottleneck was what could fit in the paper. Today publishers are capable of creating more content, but they need new methods for personalized distribution. Incremental price for publishing on the Internet is neg...

Abstract: The aim of this paper is to present an overview of the current situation in this hot topic of Multimedia Information Retrieval: Personalization. We are considering several aspects of this problem. On one hand, the user will want to have a personalized access to his image/video collections and this can be achieved by providing intuitive and natural browsing capabilities and customized features. Furthermore, the system is required to perform user profiling and to adapt the existing parameters of the system to the user needs and interest. On the other hand, it is also important to consider the devices and applications in which this technology is going to be deployed. Mobile media is a high growth area but the state-of-the-art technologies are lagging behind the consumers expectations. We are addressing in this paper precisely these three important aspects.

Sentinelli, A., Marfia, G., Gerla, M., Kleinrock, L. & Tewari, S. Will IPTV ride the peer-to-peer stream? [Peer-to-Peer Multimedia Streaming] 2007 IEEE Communications Magazine   article DOI  
Abstract: The great success of P2P systems for the purpose of file-sharing set the path to the next killer application on the Internet, P2P video streaming. Although it solves scalability issues, P2P technology experiences problems of a long start time and churn-induced instability that can greatly affect the user experience. Moreover, technical and business solutions for digital rights management are still under investigation. Great efforts are underway in both academia and industry to solve these problems, whose solution will offer a scalable, affordable, and legal TV-quality-like broadcast of content. In this article, we analyze what is available to the end user in terms of P2P video-streaming products and determine which of these are the most promising for IPTV and content distribution companies. In the following, we offer: (1) A survey of the available architectures. (2) A set of experiments on a popular peer-to-peer system, SopCast. (3) Guidelines for large scale deployment.

Seremeti, L. & Kameas, A. Multimedia ontologies 2007 MobiMedia '07: Proceedings of the 3rd international conference on Mobile multimedia communications   inproceedings DOI  
Abstract: The development and maintenance of large multimedia databases has attracted much attention nowadays from companies and organizations that held multimedia content (archives, broadcast companies, radio and TV channels, etc.). the goal is to bypass the ineffective and time-consuming process of manual searching and retrieval of multimedia content and use computers to make the content easy to be found and accessible to other parties. Thus, two critical points are identified in making the above goal a reality; effective representation as well as effective retrieval and exploitation of multimedia content. For accomplishing the above goal researchers have started to use ontologies in the field of multimedia in order to construct machine-understandable, descriptive versions of the multimedia content based on multimedia ontologies. In this paper, we present multimedia ontology characteristics, its construction and some existing multimedia ontologies.

Shin & Dong, H. Socio-technical analysis of IPTV: a case study of Korean IPTV 2007 Info - The journal of policy, regulation and strategy for telecommunications   article DOIURL  
Abstract: Purpose – This paper seeks to investigate the prospects for internet protocol TV (IPTV) from the social, economic and regulatory perspective to gain a better understanding of how IPTV will evolve and stabilize in next generation network environments.

Design/methodology/approach – Qualitative and quantitative data were collected from multiple data collection methods. The analysis is based on theoretical frameworks derived from socio-technical theories and web of stakeholder analyses.

Findings – From the socio-technical analysis, the development of IPTV implies that IPTV has been through internally-driven change (more or less technology-driven and regulatory-constrained), but from now on it will likely be driven by external factors (market and user). The web of stakeholder analysis implies that the further development of IPTV in Korea is likely to comprise multiple stages, predicated by several significant events: the deployment of Broadband Convergence Network and FTTH, the resolving of content issues, establishing standards, and the introduction of new regulatory frameworks.

Practical implications – The case of Korea offers implications for other countries that are pursuing IPTV development strategies.

Originality/value – By looking at IPTV as a sociotechnical ensemble, this paper seeks a firm understanding of the interaction among IPTV technology, its market, industry, and regulation regarding IPTV. A stakeholder analysis helps this study to address such interactions.

Shin, D. H. Potential user factors driving adoption of IPTV. What are customers expecting from IPTV? 2007 Technological Forecasting and Social Change   article DOIURL  
Abstract: Internet Protocol Television (IPTV), the convergence services of television and Internet, is being rapidly developed around the world. The advent of digital technologies has changed the convergence market dramatically with the wide diffusion of the convergent services. Using the Technology Acceptance Model as a conceptual framework and method of logistic regression, this research analyzes the demand for IPTV by drawing data from 452 consumers. Individuals' responses to questions about whether they accept IPTV are collected and combined with observations of their socio-economic status and intrinsic/extrinsic factors modified from the Technology Acceptance Model. Results of logistic regression show two variables (intrinsic and extrinsic factors) that seem to explain what influences consumer behavior towards adopting IPTV. Overall, the logistic regression model explains over 50% of the variance in the IPTV adoption. The variances shed light on the multi-open platform environment that IPTV will forge.

Thomson, J. IPTV &market, regulatory trends and policy options in Europe 2007 Proc. IET IPTV Conference 2007 - Deployment and Service Delivery   inproceedings URL  
Abstract: This paper looks at IPTV commercial offers and regulation in the five largest EU Member States (France, Germany, Italy, Spain and the UK) and four smaller Member States with the highest broadband penetration rates ranging between 20%–25% (Belgium, Denmark, the Netherlands and Sweden). IPTV is in its infancy in all of the markets surveyed. France has the largest number of IPTV subscribers so far. Alternative operator Free reported 1.26 million IPTV subscribers and France Télécom 300,000 subscribers as of end June 2006 (which should be seen in the context of 23.5 million households in France). In Italy, alternative operator FastWeb reported 870,000 subscribers as of end June 2006 (22 million households in Italy). The paper discusses a number of regulatory issues related to IPTV: replicability of incumbent operators’ IPTV offers, predatory pricing, bundling, cross-subsidy by alternative operators of their retail prices from fixed PSTN call termination revenues, must-carry obligations, and net neutrality. The paper also compares the authorisations or licences an IPTV provider would need from the broadcasting authority depending on the types of services provided.

Wei, X. & Ngo, C. Ontology-enriched semantic space for video search 2007 MULTIMEDIA '07: Proceedings of the 15th international conference on Multimedia   inproceedings DOI  
Abstract: Multimedia-based ontology construction and reasoning have recently been recognized as two important issues in video search, particularly for bridging semantic gap. The lack of coincidence between low-level features and user expectation makes concept-based ontology reasoning an attractive mid-level framework for interpreting high-level semantics. In this paper, we propose a novel model, namely ontology-enriched semantic space (OSS), to provide a computable platform for modeling and reasoning concepts in a linear space. OSS enlightens the possibility of answering conceptual questions such as a high coverage of semantic space with minimal set of concepts, and the set of concepts to be developed for video search. More importantly, the query-to-concept mapping can be more reasonably conducted by guaranteeing the uniform and consistent comparison of concept scores for video search. We explore OSS for several tasks including concept-based video search, word sense disambiguation and multi-modality fusion. Our empirical findings show that OSS is a feasible solution to timely issues such as the measurement of concept combination and query-concept dependent fusion.

Abstract: This paper is intended to be an introduction into the issues involved with delivering IPTV over DSL. IPTV technology and available broadband bandwidths are evolving to the point where DSL providers can effectively enter the market of TV delivery to their customers. However, there are still issues concerning bandwidth, codec selection, QoS, and ROI. This paper will address each of these issues and discuss the major players involved in deploying this new technology. Though the paper will not go in-depth technically about how IPTV works, it will provide a good overview of IPTV architecture, how it will be delivered from the service provider's head-end equipment to the end-user (the consumer), and the differences between IPTV architecture and legacy cable TV (television) architecture. Most importantly, it will describe the importance of why moving to IPTV is a competitive "have-to" for service providers to survive.

Kim, Y., Park, J. K., Choi, H. J., Lee, S., Park, H., Kim, J., Lee, Z. & Ko, K. Reducing IPTV channel zapping time based on viewer& surfing behavior and preference 2008 Proc. IEEE International Symposium on Broadband Multimedia Systems and Broadcasting   inproceedings DOI  
Abstract: This paper presents a method of prejoining the expected next TV channels for reducing IPTV channel zapping time with a consideration of the channel surfing behavior and the particular preference of each viewer. In this method, a home gateway of multicast protocol proxy for set-top boxes (STB) prejoins the expected and preferred channels based on aggregated data from STBs. The experimental results show that the method improves the prediction accuracy of prejoin channels with little network bandwidth overhead, which leads to reduce the channel zapping time for IPTV services.

Zhu, C. & Ye, D. Clear P2P IPTV Live Streaming System for Set-Top Box Clients 2007 Proc. 7th IEEE International Conference on Computer and Information Technology CIT 2007   inproceedings DOI  
Abstract: IPTV (Internet Protocol Television) live streaming systems with client-sever based content delivery infrastructures face scalability problems due to their high requirement at server hardware configuration and network bandwidth. This paper presents a P2P based live streaming system-"Clear Live", which tries to achieve better scalability than client-server based system. While current popular P2P IPTV systems support only PC client, our system supports both STB (Set-top Box) client and PC client. "Clear Live" is designed according to meet the requirements of STB client and IPTV services. Evaluation results demonstrate that "Clear Live" can provide high quality live streaming service to a vast number of clients with relatively low cost.
