The mass adoption of Social Media together with the proliferation and widely usage of multi-connected companion devices have tremendously transformed the TV/video consumption paradigm, opening the door to a new range of possibilities. This Special Issue has aimed at analyzing, from different point of views, the impact of Social Media and social interaction tools on the TV/video consumption area. The targeted topics of this Special Issue and a general overview of the accepted articles are provided in this Guest Editorial

Mapping Digital Media: Slovenia

The Mapping Digital Media project examines the global opportunities and risks created by the transition from traditional to digital media. Covering 60 countries, the project examines how these changes affect the core democratic service that any media system should provide: news about political, economic, and social affairs.Transition to digital broadcasting has been relatively fast and painless for Slovenia from a technical perspective, as has the spread of digital media more broadly. With the second-highest penetration of IPTV in Europe, it appears that the Slovenian population has keenly embraced new media platforms at the expense of radio, newspapers, and satellite TV. But the changes and implications for media diversity and society more broadly have stopped short of anything that could be considered a digital revolution. Key challenges remain,particularly in securing a sustainable future for the quality news sector.From a consumer and citizen's perspective, digitization has succeeded in expanding the quantity and accessibility of news and information, but not the quality and diversity of content. In combination with the lingering effects of the financial crisis, the independent performance of the media at large is under threat. This remains the over-arching challenge for policymakers

Mapping Digital Media: Malaysia

The Mapping Digital Media project examines the global opportunities and risks created by the transition from traditional to digital media. Covering 60 countries, the project examines how these changes affect the core democratic service that any media system should provide: news about political, economic, and social affairs.Malaysia has had a torrid relationship with digital. Mahathir Mohamad, the former Malaysian prime minister, fell in love with it in the 1990s when he launched the Multimedia Super Corridor, a sort of East Asian Silicon Valley, to develop the local information and communications technology industry.Two out of three Malaysians regularly use the internet (even though large areas of the East Malaysian states of Sabah and Sarawak, where nearly a fifth of the population lives, pose logistical challenges regarding infrastructure) and a third of the population have a 3G mobile subscription. Broadband household penetration in the capital, Kuala Lumpur, is 112 percent because many citizens have both fixed and mobile accounts. Nearly half the population is on Facebook with an average of 233 friends each, the greatest proportion in the world, all on social networks for an average nine hours a week. And they still seem to find enough time to watch television for three and a half hours a day and to listen to the radio for three hours.The outlook is for an expansion of internet and mobile-based platforms for news, comment, social networking, activism, and entertainment. However, a change of government is probably a prerequisite for the kinds of changes that would usher in greater diversity in broadcast and print, such as regulatory independence, repeal of the Printing Presses and Publications Act, and the dismantling of monopolies, rules on cross ownership, and political parties' ownership of media companies

Mapping Digital Media: Croatia

The Mapping Digital Media project examines the global opportunities and risks created by the transition from traditional to digital media. Covering 60 countries, the project examines how these changes affect the core democratic service that any media system should provide: news about political, economic, and social affairs.Croatia is well ahead of the curve. Experimental broadcasting via digital signals began in 2002 and the last analog television signals were switched off in September 2011. The country has the highest free-to-air digital terrestrial coverage in Europe, exceeding 99 percent of national territory, and it is the main television platform for the majority of the population.Television remains the dominant medium for both information and entertainment. However, the internet is the most trusted medium for news and information. Radio has experienced a marginal decline in listenership, but print media have been hit hardest by the globaleconomic downturn and audience migration online.In the final analysis, this report finds that policy has been responsive to digitization and that the process has done much to democratize and pluralize Croatian media. It has not yet, however, neutralized the power of dominant media organizations, or indeed the influence wielded by political elites and advertisers. There is also evidence that in response to digitization, journalism across sectors has become increasingly tabloid and oriented towards soft news, and there are uncertainties as regards the sustainability of public interest media

Quasi-cyclic LDPC codes of column-weight two using a search algorithm

Copyright © 2007 G. Malema and M. Liebelt. This is an Open Access article distributed under the Creative Commons Attributions License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.This article introduces a search algorithm for constructing quasi-cyclic LDPC codes of column-weight two. To obtain a submatrix structure, rows are divided into groups of equal sizes. Rows in a group are connected in their numerical order to obtain a cyclic structure. Two rows forming a column must be at a specified distance from each other to obtain a given girth. The search for rows satisfying the distance is done sequentially or randomly. Using the proposed algorithm regular and irregular column-weight-two codes are obtained over a wide range of girths, rates, and lengths. The algorithm, which has a complexity linear with respect to the number of rows, provides an easy and fast way to construct quasi-cyclic LDPC codes. Constructed codes show good bit-error rate performance with randomly shifted codes performing better than sequentially shifted ones.Gabofetswe Malema and Michael Liebel

CHORUS Deliverable 3.3: Vision Document - Intermediate version

The goal of the CHORUS vision document is to create a high level vision on audio-visual search engines in order to give guidance to the future R&D work in this area (in line with the mandate of CHORUS as a Coordination Action). This current intermediate draft of the CHORUS vision document (D3.3) is based on the previous CHORUS vision documents D3.1 to D3.2 and on the results of the six CHORUS Think-Tank meetings held in March, September and November 2007 as well as in April, July and October 2008, and on the feedback from other CHORUS events. The outcome of the six Think-Thank meetings will not just be to the benefit of the participants which are stakeholders and experts from academia and industry – CHORUS, as a coordination action of the EC, will feed back the findings (see Summary) to the projects under its purview and, via its website, to the whole community working in the domain of AV content search. A few subjections of this deliverable are to be completed after the eights (and presumably last) Think-Tank meeting in spring 2009

Survey of Transportation of Adaptive Multimedia Streaming service in Internet

[DE] World Wide Web is the greatest boon towards the technological advancement of modern era. Using the benefits of Internet globally, anywhere and anytime, users can avail the benefits of accessing live and on demand video services. The streaming media systems such as YouTube, Netflix, and Apple Music are reining the multimedia world with frequent popularity among users. A key concern of quality perceived for video streaming applications over Internet is the Quality of Experience (QoE) that users go through. Due to changing network conditions, bit rate and initial delay and the multimedia file freezes or provide poor video quality to the end users, researchers across industry and academia are explored HTTP Adaptive Streaming (HAS), which split the video content into multiple segments and offer the clients at varying qualities. The video player at the client side plays a vital role in buffer management and choosing the appropriate bit rate for each such segment of video to be transmitted. A higher bit rate transmitted video pauses in between whereas, a lower bit rate video lacks in quality, requiring a tradeoff between them. The need of the hour was to adaptively varying the bit rate and video quality to match the transmission media conditions. Further, The main aim of this paper is to give an overview on the state of the art HAS techniques across multimedia and networking domains. A detailed survey was conducted to analyze challenges and solutions in adaptive streaming algorithms, QoE, network protocols, buffering and etc. It also focuses on various challenges on QoE influence factors in a fluctuating network condition, which are often ignored in present HAS methodologies. Furthermore, this survey will enable network and multimedia researchers a fair amount of understanding about the latest happenings of adaptive streaming and the necessary improvements that can be incorporated in future developments.Abdullah, MTA.; Lloret, J.; Canovas Solbes, A.; García-García, L.

Digitalna televizija u Hrvatskoj: Postaje li televizija novi medij?

We live in a multimedia world and media convergence is our everyday reality. Technological improvements cause important transformations in society and the economy, and the media are the first to be changed. Digitisation transforms the media, especially television, into new media with numerous possibilities for new products and services. The main characteristic of this process in Croatia is the fact that implementation precedes development strategies or plans. Furthermore, the lack of public discussion enables these processes to remain far away from citizens who do not understand them or are not motivated to understand them. The proliferation of new digital channels (terrestrial, cable, satellite or broadband) as well as fragmentation of the mass audience make this process even more complex. Technological improvements have produced a new multimedia environment breaking down the traditional boundaries between telecommunications, computers and the audiovisual industries. As in many countries in the region, the public service television in Croatia is faced with a program identity crisis and at the same time is fighting for stable financing. Regarding the process of general digitization and media convergence, we must ask if it is possible to predict the future of the ‘old media’, especially of television, which is still the most influential. If it wants to survive, public service television has to reorganize and redefine itself as a converged, multimedia public service.Živimo u multimedijskom društvu, u kojem je medijska konvergencija svakodnevna. Tehnološki razvoj prouzročio je značajne transformacije u društvu i gospodarstvu, pa su i mediji izloženi neprestanim promjenama. Zahvaljujući digitalizaciji koja medije transformira u potpuno nove, otvarajući im prostor za brojne mogućnosti, proizvode i usluge, i televizija se našla u vrtlogu promjena. Za taj proces u Hrvatskoj karakteristično je da implementacija prethodi razvojnoj strategiji i planiranju, a nedostatak javne rasprave dodatno povećava nerazumijevanje. Proliferacija novih digitalnih kanala (zemaljskih, kabelskih, satelitskih i široko pojasnih) te fragmentacija masovne publike, dodatno usložnjavaju proces. Tehnološka dostignuća omogućavaju razvoj novog multimedijskog okruženja, koji pritom ruši tradicionalne granice, one koje su postojale između telekomunikacija, računala i audiovizualne industrije. Kao u većini zemalja u regiji, javna televizija se i u Hrvatskoj suočava sa sve izraženijom krizom identiteta te rastućim problemom čuvanja stabilnog financiranja. Kada je riječ o općoj medijskoj digitalizaciji i konvergenciji, nameće se pitanje je li uopće moguće predvidjeti budućnost sada već ‘starih medija’, posebice televizije, koja još uvijek uspijeva zadržati primat najutjecajnijeg medija. Opstanak javnog servisa moguć je upravo ako se i sam multimedijski redefinira i restrukturira
