Interactive searching and browsing of video archives: using text and using image matching

Over the last number of decades much research work has been done in the general area of video and audio analysis. Initially the applications driving this included capturing video in digital form and then being able to store, transmit and render it, which involved a large effort to develop compression and encoding standards. The technology needed to do all this is now easily available and cheap, with applications of digital video processing now commonplace, ranging from CCTV (Closed Circuit TV) for security, to home capture of broadcast TV on home DVRs for personal viewing. One consequence of the development in technology for creating, storing and distributing digital video is that there has been a huge increase in the volume of digital video, and this in turn has created a need for techniques to allow effective management of this video, and by that we mean content management. In the BBC, for example, the archives department receives approximately 500,000 queries per year and has over 350,000 hours of content in its library. Having huge archives of video information is hardly any benefit if we have no effective means of being able to locate video clips which are of relevance to whatever our information needs may be. In this chapter we report our work on developing two specific retrieval and browsing tools for digital video information. Both of these are based on an analysis of the captured video for the purpose of automatically structuring into shots or higher level semantic units like TV news stories. Some also include analysis of the video for the automatic detection of features such as the presence or absence of faces. Both include some elements of searching, where a user specifies a query or information need, and browsing, where a user is allowed to browse through sets of retrieved video shots. We support the presentation of these tools with illustrations of actual video retrieval systems developed and working on hundreds of hours of video content

On the design of television as a service based on average TV watching

Ten households were interviewed about their TV watching to inform the design of TV services. Our participants were average TV viewers who had Internet access but were not technically advanced or frequent users of the Internet as a source for TV material. We found that the flow of programs that broadcast television brings to viewers was the most important motivation for our participants to turn to the TV on-demand possibilities they had access to. Examples of triggers were social cues from people talking about things seen on TV, or time-shifting issues such as missing all or part of programs in the broadcast flow. Special interests such as sports were also a strong motivation for on-demand behavior. For the viewers, linear and on-demand TV watching was intertwined. We conclude that on-demand services should be integrated with broadcast TV in the design of future TV services

How to choose and how to watch: an on-demand perspective on current TV practices

In Sweden, digital TV services have until very recently not been accessible to most people through the TV set. At the same time, TV channels offer more and more content on the web and the majority of the population has access to high-speed internet connections. A web survey aimed at investigating attitudes and behavior related to on-demand TV was distributed in December 2008 to 52 households in an experimental, open (operator neutral) access network in Sweden. Questions were posed on TV arrangements, habits and attitudes; social aspects of TV watching; watching film or TV on-demand; and watching film or TV using the computer. Complementary interviews were also performed with participants that were not part of the experimental environment. Results show that participants in the studies understood and felt a need for time-shift and on-demand TV services: time-shift needs for re-scheduling, catch-up and repeats were expressed as well as on-demand needs for movies and for accessing otherwise unavailable TV content. Support for on-demand TV could also be found in that subjects reported little need for viewing TV content according to a broadcast schedule, with the main exception of news, sports events and other live broadcasts

An Ecological Framework to Assess Sustainability Impacts for an Evolving Consumer Electronic Product System

Consumer electronics have revolutionized the manner in which we work, read, and entertain ourselves. However, this transformation comes at a high cost, with significant energy input and emissions releases across all stages of the electronic product life cycle. The limited success of per product efficiency improvements, often formulated in the field of industrial ecology, does not address the electronic product system as a whole because escalating consumption may actually offset any individual impact reductions. Additionally, existing industrial ecology models fail to effectively capture energy, material, and waste flows associated with real consumption patterns, as consumers purchase, use, and discard a group of interrelated devices such as desktops, laptops, printers, mobile phones, and digital cameras. To address this challenge, this dissertation develops and applies novel industrial ecology methodologies to more effectively characterize changes to rapidly evolving and interrelated product systems. Notably, these approaches borrow heavily from underutilized biological ecology concepts from community ecology and optimal foraging theory, but adapted for use as applied to a complex product system like consumer electronics. These approaches can lead to more effective design, production, green purchasing decisions, and end of life practices and policies, while at the same time expand industrial ecology\u27s traditional focus on the ecosystem metaphor and ‘per product’ approaches and strengthen its connection to the source science: biological ecological roots

ULOGA NOVIH GENERACIJA HIBRIDNIH TV TEHNOLOGIJA U OBRAZOVANJU

In this paper, is carried out systematic information and communication analysis of role of implementing hybrid television technologies in the process of e-education technology, which is possible because of technological future of new TV generation. The authors suggest that the development of new television technologies is in constant communication progress and it is correlated with technological changes (transition from black and white to color, the introduction of stereo / surround sound, and the possibility of new high-resolution image technology which is offered by new generation television receivers and video on demand) that in the technological and communicational terms have not yet been completed. At the present stage of technological and media development of the global world, more than 400 million citizens have direct access to the Internet with a broadband Internet connection (10 Mbps to 100 Mbps), which allows to citizens delivering of media content in high-tech resolution (720p or 1080p). For these reasons, traditional television "providers" respond to the challenges of hybrid television technology with new development and investment deals. Today the media "providers" in education are developing new customer services and media services for the provision and delivery of the new educational video content via Internet Protocol (IP technology) as well as other videos ("tablet") which are mounted on mobile devices of the citizens. Providers of educational media ("high-definition educational contents") are in the front of new communicational, educational and technological challenges. The authors, based on the set of theoretical assumptions and empirical research about the place and role of hybrid technology in a new generation of TV in E-education, give a scientific formulation of implementing new features and models of education that are provided by a new hybrid television technology through a new generation of television receivers. In conclusion, on the basis of the genetic-structural and functional analysis of the convergence of media, the authors explicate the historical value of television technology and propose new educational opportunities (video on demand) which provide a hybrid television technology with unlimited social, hardware and software and technological values and communication capabilities of the new generation TV in the future of E-education.U radu se provodi sustavna informacijska i komunikacijska analiza uloge implementacijskih hibridnih televizijskih tehnologija u procesu E- obrazovanja koje nam omogućuje tehnološka budućnost nove TV-generacije. Autori ukazuju kako je razvoj novih televizijskih tehnologija u stalnom komunikacijskom napretku i korelaciji s tehnološkim promijenama (prijelaz iz crno bijele boje u kolor, uvođenje stereo / surround zvuka, te nove mogućnosti visoke tehnološke razlučivosti slike koje nam pružaju nove generacije televizijskih prijemnika i videa na zahtjev) koje u tehnološkom i komunikološkom smislu još nisu završene. Na današnjem stupnju tehnološkog i medijskog razvoja globalnog svijeta, više od 400 milijuna građana ima direktan pristup Internetu s širokopojasnom internetskom vezom (od 10 Mbps i do 100 Mbps) koja omogućuje građanima isporuku medijskih sadržaja visoke tehnološke rezolucije (od 720p ili 1080p). Iz tih razloga tradicionalni televizijski »provideri« reagiraju na izazove hibridnih televizijskih tehnologija s novim razvojnim investicijama i ponudama. Danas medijski »provideri« u području obrazovanja razvijaju nove korisničke usluge i medijske servise za pružanje i dostavljanje građanima novih obrazovnih video sadržaje putem internetskih protokola (IP tehnologije) kao i drugih videa (»tableta«) koji su ugrađeni na mobilnim uređajima građana. Pružatelji obrazovnih medijskih sadržaja (»high-definition obrazovni sadržaji«) su pred novim komunikološkim, tehnološkim i obrazovnim izazovima. Autori u radu, na temelju postavljenih teorijskih postavki te provedenih empirijskih istraživanja o mjestu i ulozi hibridnih tehnologija nove TV generacije u E-obrazovanju, znanstveno formuliraju nove implementacijske mogućnosti i modele obrazovanja koje nam pružaju nove hibridne televizijske tehnologije putem televizijskih prijemnika nove generacije. U zaključku, na temelju provedene genetsko-strukturalne i funkcionalne konvergentne medijske analize, autori ekspliciraju povijesne vrijednosti televizijskih tehnologija te predlažu nove obrazovne mogućnosti (videa na zahtjev) koje nam pružaju hibridne televizijske tehnologije s neograničenim društvenim, hardwerskom, softwerskim i tehnološkim vrijednosnim komunikacijskim mogućnostima nove TV generacije u budućnosti E- obrazovanja

Distributed multimedia systems

A distributed multimedia system (DMS) is an integrated communication, computing, and information system that enables the processing, management, delivery, and presentation of synchronized multimedia information with quality-of-service guarantees. Multimedia information may include discrete media data, such as text, data, and images, and continuous media data, such as video and audio. Such a system enhances human communications by exploiting both visual and aural senses and provides the ultimate flexibility in work and entertainment, allowing one to collaborate with remote participants, view movies on demand, access on-line digital libraries from the desktop, and so forth. In this paper, we present a technical survey of a DMS. We give an overview of distributed multimedia systems, examine the fundamental concept of digital media, identify the applications, and survey the important enabling technologies.published_or_final_versio
