There was a lot of interest in multicast communications within this decade as it is an essential part of many network applications, e.g. video-on-demand, etc. In this paper, we model flow rate allocation for application overlay as a utility based optimization problem constrained by capacity limitations of physical links and overlay constraints. The optimization flow control presented here addresses not only concave utility functions which are suitable for applications with elastic traffics, but also especial forms of non-concave utilities that are used to model applications with inelastic traffics, which might demand for hard delay and rate requirements. We then propose an iterative algorithm as the solution to the optimization flow control problem and investigate especial forms of non-concave utilities that are supported by this model. Simulation results show that the iterative algorithm can be used to deal with sigmoidal-like utilities which are useful for modeling real-time applications such as live streaming.

A system supporting video on demand is modeled in the process calculus CCS (Calculus of Communicating Systems), while some properties are expressed in a temporal logic and verified by means of the model checkers of the North Carolina Concurrency Workbench. This application was chosen as a case study to evaluate the usefulness of a methodology, by means of which a property is checked on reduced models obtained issuing abstractions of the system on the basis of the formula. Experimental results are shown and discussed.

Java is largely used to develop distributed and concurrent systems, but testing multithreaded systems cannot guarantee the quality of the software; in contrast, verification techniques give us a higher confidence about the system and, among these, model checking methods automatically establish properties of complex systems. Such techniques are usually applied to specification languages, and several environments exist to verify temporal properties of concurrent specifications. In this paper we present an attempt to apply model checking techniques for verifying a subset of multithreaded Java programs. In particular, we use a tool based on the selective mu-calculus logic to check systems described through the CCS specification language.

Verification of a concurrent system can be accomplished by model checking the properties on a structure representing the system; this structure is, in general, a transition system which contains a prohibitive number of states. In this paper, we apply a method to reduce the state explosion problem by pointing out the events of the system to be ignored on the basis of the property to be verified. We evaluate the method by means of a real application used as a case study: the system is specified by a CCS program, then the program is reduced by means of syntactic rules; afterwards, the corresponding transition system is built by means of a non-standard operational semantics, which performs further reductions during the construction. Prototype tools perform both kinds of reductions; finally the required properties are checked by means of the model checkers of the CWB-NC.

Software engineering research is driven by the aim of making software development more dynamic, flexible and evolvable. Nowadays the emphasis is on the evolution of pre-existing sub-systems and component and service-based development, where often only a part of the system is totally under control of the designer, most components being remotely operated by external vendors. In this context, we tackle the following problem: given the formal specification of the (incomplete) system, say it p, already built, how to characterize collaborators of p to be selected, based on a given communication interface L, so that a given property ϕ is satisfied. Using properties described by temporal logic formulae and systems by CCS processes, if ϕ is the formula to be satisfied by the complete system, an efficient and automatic procedure is defined to identify a formula ψ such that, for each existing process q satisfying ψ, the process (p | q) \ L satisfies ϕ. Important features of this result are simplicity of the derived property ψ, compared to the original one, and scalability of the verification process. Such characteristics are necessary for applying the method to both incremental design and system evolution scenarios where p is already in place, and one needs to understand the specification of the functionality of the new component that should correctly interact with p. Indeed, in general, finding a suitable partner for p is easier than finding a complete system satisfying the global property. Moreover, in this paper it is shown how ψ can be used also to select a set of possible candidate processes q through a property-directed and structural heuristic. From the verification point of view, the description of the lacking component through a logic formula guarantees correctness of the integration with p of any process that exhibits a behaviour compliant with the inferred formula.

New Internet services like video on-demand, high definition IPTV, high definition video conferences and some real time applications have strong QoS requirements regarding losses, delay, jitter, etc. This work addresses the challenge of guaranteeing quality of service (QoS) in the Internet from a statistical point of view. Three lines of work are proposed. The first one is about the estimation of the QoS parameters from traffic traces (in the context of large deviation theory and effective bandwidth). The second one, address the admission control problem from results of the many sources and small buffer asymptotic. Finally, the third line focuses on the estimation of QoS parameters seen by an application based on end-to-end active measurements and statistical learning tools.

Dynamiczny rozwój technologii, w tym smartfonów i internetu, przekształca praktyki religijne, czyniąc nowe technologie istotną częścią doświadczenia duchowego. John Dyer w książce People of the Screen analizuje, jak cyfryzacja wpływa na sposób korzystania z Biblii, koncentrując się głównie na protestantach-ewangelikach. Opisuje, jak zdominowali oni produkcję i konsumpcję cyfrowej Biblii, oraz ukazuje różnice między cyfrowym a tradycyjnym czytaniem Pisma Świętego. Autor łączy perspektywy mediów cyfrowych, teologii i socjologii, podkreślając psychologiczne i społeczne skutki tej transformacji. Recenzja sugeruje, że ujęcie szerszych tradycji religijnych, takich jak katolicyzm czy judaizm, mogłoby wzbogacić analizę i nadać jej bardziej globalny wymiar.

Saizescu (1932-2013) este un regizor român emblematic pentru canonul popular românesc. Voi încerca mai jos să trasez liniile principale ale filmelor lui, care să le cuprindă atât pe cele populare, cât și pe cele mai puțin populare, prin intermediul unor criterii de clasificare relevante pentru particularul acestei cinematografii. Nu iau în calcul serialul regizat de Geo Saizescu, ci numai lungmetrajele sale (dinainte și după 1989) și mediumetrajul Doi vecini (În tabelul 3 se găsesc detalii ale tuturor celor 16 filme incluse). Aș vrea să schițez trei din axele pe care le consider esențiale pentru figura lui Geo Saizescu: popularitatea, genurile și geografia.

La enseñanza de las nuevas figuras contractuales -en concreto, los modelos de negocios de Netflix y de Spotify-nos supone importantes desafíos, en especial, en el campo contractual. El siglo xxi se nos presenta un mundo globalizado en el cual los fenómenos jurídicos, especialmente los contratos, son caracterizados por la internacionalidad, la diversidad de fuentes y una fuerte tendencia hacia la aplicación de normas de tradición anglosajona. Ello nos conduce a la necesidad de realizar un estudio profundizado de nuevos paradigmas que deben ser enfrentados por los docentes universitarios y por los profesionales del derecho. Es por ello por lo que, teniendo en cuento la situación planteada, es menester una apertura hacia la comprensión integral de los derechos intelectuales en forma transversal, ya que la aparición de estos numerosos desafíos constituye la razón trascendental que justifica el estudio profundizado de aquellos.

Features provide extensions to a basic service, but in new systems users require much greater flexibility oriented towards their needs. Traditional features do not easily allow for this. We propose policies as the features of the future. Policies can be defined by the end-user, and allow for the use of rich context information when controlling calls. This paper introduces an architecture for policy definition and call control by policies. We discuss the operation of systems based on such an architecture. An important aspect of the architecture is integral feature interaction handling.

RESUMEN. Este trabajo analiza las representaciones mediáticas de personas LGBTIQA+ en ocho plataformas VoD disponibles en México, para identificar sus patrones productivos y simbólicos. Se recurre a los Estudios Culturales para problematizar la lucha ideológica detrás de la producción cultural global. El trabajo se sustenta en el análisis de 152 contenidos audiovisuales con temáticas de la diversidad sexual disponibles en dichas plataformas. Los contenidos fueron analizados a nivel de ficha técnica y de representaciones mediáticas. Los resultados muestran que los contenidos ofertados reflejan, en su mayoría, los contextos, aspiraciones, patrones de poder y protagonismos provenientes del Norte Global, evidenciando su carácter hegemónico y omitiendo las realidades situadas en países del Sur Global, como México. Se concluye que los contenidos que circulan en este tipo de plataformas, aunque con una aspiración global, suponen un campo cultural e identitario en proceso de mercantilización donde los grupos subalternos deben luchar por su enunciación.

User Generated Content (UGC) is re-shaping the way people watch video and TV, with millions of video producers and consumers. In particular, UGC sites are creating new viewing patterns and social interactions, empowering users to be more creative, and developing new business opportunities. To better understand the impact of UGC systems, we have analyzed YouTube, the world's largest UGC VoD system. Based on a large amount of data collected, we provide an in-depth study of YouTube and other similar UGC systems. In particular, we study the popularity life-cycle of videos, the intrinsic statistical properties of requests and their relationship with video age, and the level of content aliasing or of illegal content in the system. We also provide insights on the potential for more efficient UGC VoD systems (e.g. utilizing P2P techniques or making better use of caching). Finally, we discuss the opportunities to leverage the latent demand for niche videos that are not reached today due to information filtering effects or other system scarcity distortions. Overall, we believe that the results presented in this paper are crucial in understanding UGC systems and can provide valuable information to ISPs, site administrators, and content owners with major commercial and technical implications.

Video streaming is a major contributor to modern Internet traffic. In this paper, we use data collected from a campus edge network to characterize two popular video streaming services: Netflix and Twitch. While these video streaming services provide inherently different types of content, namely videoon-demand and live-streaming, they nonetheless exhibit many similarities in traffic patterns, protocol usage, content popularity, and growth. We identify seven similarities and differences, and discuss how these could be leveraged to improve streaming video content delivery on the Internet in the future.

College television news programs are journalist training grounds and should encourage students to adopt best practices in reporting news and preparing news for distribution. While programs often distribute content via campus cable and websites, many distribute content via social media such as Facebook. Video consumers treat Facebook video differently than other videos. Over 85% of Facebook users watch video with muted sound. Prior research found captioning problems on college and local television news websites. This study examines how college news programs meet the captioning challenge when distributing video via Facebook and found most programs do not caption their Facebook videos.

This study explores how the emergence of legal distribution channels affects digital piracy. We use online video-on-demand services as a proxy for legal distribution channels and investigate how increased satisfaction with this service influences the consumption of pirated content. Data for this study were collected through an online survey of a representative sample of 332 participants and analyzed using the Structural Equation Modeling approach. The findings indicate that greater use of subscription-based video-on-demand services significantly reduces the consumption of pirated video content. Additionally, features such as content richness, system quality, and recommendation mechanisms are crucial in shaping user satisfaction with such services. Based on these findings, this study recommends that streaming service providers and policymakers promote legal digital consumption further and reduce piracy

Advancements in storage technology along with the fast deployment of high-speed networks has allowed the storage, transmission and manipulation of multimedia information such as text, graphics, still images, video and audio to be feasible. Our study focused on the performance of the mass storage system for a large-scale video-on-demand server. Different video le stripping schemes, such as application level stripping and device driver level stripping, were examined in order to study scalability and performance issues. To study the impact of di erent concurrent access patterns on the performance of a server, experimental results were obtained on group access on a single video le and multiple group accesses on multiple video les. All of our experiments were conducted on a fully con gured Silicon Graphics Inc. Onyx computer system. The Onyx machine was connected to 31 SCSI-2 channels which have 496 Gigabyte disk storage, 20 MIPS R4400 processors, and 768 MByte main memory. From the experimental results, the storage system of Onyx machine can potentially provide about 360 concurrent video accesses with guaranteed quality of service.

For a realistic traffic mix, we evaluate the hit rates attained in a two-layer cache hierarchy designed to reduce Internet bandwidth requirements. The model identifies four main types of content, web, file sharing, user generated content and video on demand, distinguished in terms of their traffic shares, their population and object sizes and their popularity distributions. Results demonstrate that caching VoD in access routers offers a highly favorable bandwidth memory tradeoff but that the other types of content would likely be more efficiently handled in very large capacity storage devices in the core. Evaluations are based on a simple approximation for LRU cache performance that proves highly accurate in relevant configurations.

In this paper, I respond to the call by Jedlowski on the need to study the economy and environment under which African film is distributed. The paper explores the implications and increasing presence of film streaming in Nigeria within the economic, cultural, and ethical ambits. The paper examines the influence of digital film distribution practices on Nigeria's film industry known as Nollywood, and impacts on corporate, consumer, and industry practices. Through primary data gathered from film industry stakeholders and complemented with secondary sources, the paper argues that there is a need for self-regulation and consumer protection against socioeconomic and technological exploitation in the film industry. The paper concludes that agencies of the government must begin infrastructural renewal, including high-tech personnel with relevant digital skills to engage corporate interests. The paper contributes to discourses on emerging digital media content distribution in the Global South and film distribution economies in developing nations.

In this paper, we derive an analytical model for the evaluation of the performance of a Video on Demand (VoD) system. The model estimates the mean waiting time achievable by the Popularity-Aware Partial cAching (PAPA) algorithm from our previous work. Two approximation strategies are proposed for low computational complexity. Furthermore, we also consider the influence of a starting point shift on the quality of experience and combine the two factors into a universal user satisfaction metric. In order to find the relation between the two impairments, waiting time and starting point shift, sophisticated subjective tests are performed. With the final score model, a more comprehensive evaluation of the system can be obtained with very low computational complexity.

Video presentation systems currently available provide users with only a few functionality options. With the introduction of an Internet-based back channel, the way is now open for wide-spread interactive video systems. The convergence of the Internet with broadcast services gives rise to a variety of new application types. It extends the opportunity for a client to retrieve additional video content-related information or to affect the content of a video presentation itself, whether it is a live broadcast or a video-on-demand. The system presented in this paper represents such an interactive application with a number of new options concerning local and global functionalities. To influence video content, a "off-screen" hyperlink technique is introduced. This technique enables the annotation of hyperlinks on a separate display from the actual information with which it is linked. In the following, a scenario is given demonstrating the advantages of such a technique.

The Video on Demand (VoD) service is becoming a dominant service in the telecommunication market due to the great convenience regarding the choice of content items and their independent viewing time. However, it comes with the downsides of high server storage and capacity demands because of the large variety of content items and the high amount of traffic generated for serving each request. Storing part of the popular contents on the peers brings certain advantages but, it still has issues regarding the overall traffic in the core of the network and the scalability. Therefore We propose a P2P assisted model for streaming VoD contents that takes advantage of the clients unused uplink and storage capacity to serve requests of other clients and present popularity based schemes for distribution of both the popular and unpopular contents on the peers with the objective to reduce the streaming traffic in the core of the network, improve the responsiveness of the system and increase its scalability.

The Video on Demand (VoD) service is becoming a dominant service in the telecommunication market due to the great convenience regarding the choice of content items and their independent viewing time. However, due to its high traffic demand nature, the VoD streaming systems are faced with the problem of huge amounts of traffic generated in the core of the network, especially for serving the requests for content items that are not in the top popularity range. Therefore, we propose a peer assisted VoD model that takes advantage of the clients unused uplink and storage capacity to serve requests for less popular items with the objective to keep the traffic on the periphery of the network, reduce the transport cost in the core of the network and make the system more scalable.

Optical networking is the cornerstone of the Future Internet as it provides the physical infrastructure of the core backbone networks. Recent developments have enabled much better quality of service/experience for the end users, enabled through the much higher capacities that can be supported. Furthermore, optical networking developments facilitate the reduction of complexity of operations at the IP layer and therefore reduce the latency of the connections and the expenditures to deploy and operate the networks. New research directions in optical networking promise to further advance the capabilities of the Future Internet. In this book chapter, we highlight the latest activities of the optical networking community and in particular what has been the focus of EU funded research. The concepts of flexible and cognitive optical networks are introduced and their key expected benefits are highlighted. The overall framework envisioned for the future cognitive flexible optical networks are introduced and recent developments are presented.

Last generation video encoding standards increase computing demands in order to reach the limits on compression efficiency. This is particularly the case of H.264/AVC specification that is gaining interest in industry. We are interested in applying parallel processing to H.264 encoders in order to fulfill the computation requirements imposed by stressing applications like video on demand, videoconference, live broadcast, etc. Given a delivered video quality and bit rate, the main complexity parameters are image resolution, frame rate and latency. These parameters can still be pushed forward in such a way that special purpose hardware solutions are not available. Parallel processing based on off-the-shelf components is a more flexible general purpose alternative. In this work we propose a hierarchical parallelization of H.264 encoders very well suited to low cost clusters. Our proposal uses MPI message passing parallelization at two levels: GOP and frame. The GOP level encodes simultaneously several groups of consecutive frames and the frame level encodes in parallel several slices of one frame. In previous work we found that GOP parallelism alone gives good speed-up but imposes very high latency, on the other side frame parallelism gets less efficiency but low latency. Combining both approaches we obtain a compromise between speed-up and latency and then a broader spectrum of applications can be covered.

Frente a la tendencia académica de analizar más las series de ficción, este artículo investiga las series documentales producidas por las cuatro plataformas que más títulos han generado de este tipo de obra audiovisual: Netflix, Movistar Plus+, Max y Prime Video. Se parte de la hipótesis de que la serialización del documental es una estrategia de innovación en un mercado televisivo saturado. Para estudiar la producción existente, a falta de una base de datos oficial, se ha elaborado un catálogo que cartografía este ámbito. Se obtiene la cifra de 127 series documentales producidas entre marzo de 2016 y junio de 2024. El análisis evidencia falta de reflexión y consistencia en la utilización del concepto «documental» o la idea de originalidad por parte de algunas plataformas, así como información incompleta en los metadatos que ofrecen. La cuantificación de datos demuestra que desde 2020 la producción anual de series documentales ha aumentado considerablemente, pues se consolida como una línea de producción atractiva para plataformas y audiencias. También se detecta que la serialidad suele darse con pocas entregas, normalmente entre dos y cuatro capítulos, y que las series suelen presentar temáticas recurrentes, como deporte o crímenes reales, mediante las que algunas plataformas, como Prime Video y Netflix o Max, tratan de diferenciarse del resto. Palabras clave: Documental, series de televisión, innovación, plataformas VoD, streaming. ENG Documentary serialisation as an innovation strategy in Spanish streaming platforms: mapping and dominant trends (2016-2024) Abstract. Although academic attention has focused more on analysing fiction series, this article investigates the documentary series produced by the four platforms that have generated the most titles of this type of audiovisual work: Netflix, Movistar Plus+, Max y Prime Video. This research is based on the hypothesis that the serialisation of documentaries is a strategy for innovation in a saturated television market. In order to study the existing production, in the absence of an official database, a catalogue has been drawn up that maps this field evincing a total of 127 documentary series produced between March 2016 and June 2024. The analysis evidences a lack of reflection and consistency in the use of the concept of «documentary» or the idea of originality by some platforms, as well as incomplete information in the metadata they offer. The quantification of data shows that since 2020 the annual production of documentary series has increased considerably, consolidating itself as an attractive line of production for platforms and audiences. It is also detected that seriality usually occurs with few chapters, frequently between 2 and 4 chapters, and that series usually present recurring topics, such as sports or real crimes, through which some platforms, as Prime Video and Netflix or Max respectively, try to differentiate themselves from the rest.

O trabalho visa apresentar as possibilidades educacionais de utilização de canais de vídeo transmitidos via Internet. Para isso, foi realizada uma experiência com um curso de Construções Geométricas Elementares para alunos de escolas públicas divididos em duas turmas. Além disso, pretende-se aferir o uso de tais canais de vídeos sob duas perspectivas: na primeira, o vídeo como recurso principal e como auxiliar na segunda. Dessa forma, buscam-se as peculiaridades de cada experiência realizada através da análise das duas situações de uso do vídeo. Para a coleta de dados, foram utilizados formulários, questionários e exercícios realizados durante o curso, bem como a captura de imagens dessas interações para possibilitar a melhor análise da situação. O trabalho, portanto, conseguiu gerar materiais didáticos em diversas mídias e para várias plataformas como computador e dispositivos móveis. Além disso, serviu para realizar a inclusão digital e aprendizado de conteúdos matemáticos de uma maneira diferente da tradicional. Os conteúdos digitais produzidos, principalmente, o vídeo possibilitam a discussão acerca da ideia de memória por proporcionar o avanço e o retrocesso de trechos específicos do material por parte do aluno ou qualquer usuário. Palavras-chave: vídeo educacional; educação a distância; educação matemática. A busca por conteúdos audiovisuais em sítios de armazenamento e compartilhamento de vídeo na Internet, bem como as quantidades dessas mídias disponíveis na Web tem crescido nos últimos anos. Esses usuários estão interessados em divulgar suas produções em local acessível, gratuito e de ampla abrangência, cujo acesso a outros meios de comunicação para tal finalidade seria mais difícil . O uso do vídeo em ambiente escolar tem crescido, principalmente, usado por professores para levantar discussões, complementar assuntos e apresentar assuntos sob outras perspectivas. Esse avanço só foi possível devido ao avanço da Internet em banda larga, a redução dos preços de equipamentos como câmeras digitais e Computadores Pessoais (PC). A facilidade de uso e aquisição de softwares gratuitos também contribuiu para os trabalhos com vídeos. A pesquisa, portanto, trabalhou a utilização do vídeo como recurso educativo sob duas abordagens educativas: principal (primeiro grupo) e auxiliar (segundo grupo). Desse modo, buscou-se identificar as possibilidades de como divulgar e utilizar conteúdos audiovisuais educacionais de maneira fácil e eficiente, sem muitos recursos financeiros, em uma plataforma acessível a todos, organizada e de ampla abrangência. Assim, um curso de Construções Geométricas Elementares (CGE) foi desenvolvido com assuntos relativos à Geometria Plana para alunos de Ensino Médio como forma de desenvolver, colocar em prática, acompanhar, analisar, aferir e identificar fielmente todas as etapas de constituição dos materiais audiovisuais. O objetivo geral deste trabalho é identificar as possibilidades de utilização um canal de vídeos transmitidos via Internet, com conteúdo educacional seja na modalidade a distância, semipresencial, ou presencial. Os conceitos básicos de Geometria Plana e a apresentação do Geonext foram reunidos em vídeos e disponibilizados no Canal de Geometria Dinâmica (CGD) do YouTube, acessado através do endereço:

Resumen: En América Latina existe una reina en número de ventanas de exhibición ocupadas y en volumen de inversión publicitaria capturado: La televisión. Sin embargo, proyecciones económicas recientes no la identifican como el medio de mayor crecimiento, sino que señalan a los teléfonos móviles como el sector que más está extendiendo su influencia en el continente. El objetivo de este trabajo es realizar una primera recopilación de esta información y considerar si existen elementos suficientes como para creer en esta defenestración. Para ello he tomado como punto de referencia la teoría de la larga cola 1 y he intentado aplicar su caracterización para entender si estamos ante un nuevo modelo de negocio tan viable que puede cambiar el paradigma. 1 brought to you by CORE View metadata, citation and similar papers at core.ac.uk

The article presents the basics of the research toolkit of the digital humanist. Digital humanities is a new research trend that has emerged in the 21st century. The main object of research of digital humanists is digital culture and digitized artifacts of the past. Digital humanists are increasingly studying large data sets -known as big data. This can include textual, media and audio data. In order for them to become the subject of cognition, they should then be converted to numerical form. ICT tools are used to study digital creations. With their help it is possible to: a) retrieve data from databases and digital archives, b) prepare them for study, c) analyse them, d) use visualization methods and prepare research reports. The paper shows examples of such research conducted using digital tools. For this purpose, the R programming language, a special development environment, were used: R Studio and the programming package: ggplot2 were used.

techniques develop, various applications are increasing including multi-user social networking and education applications that involve talking avatars. Due to a lack of sensory information for full face and body motion capture in consumer-grade VR, most VR applications do not show a synced talking face and body. We propose a novel method, targeted for VR applications, for talking face synced with audio with an upper-body inverse kinematics. Our system presents a mirrored avatar of a user himself in single-user applications. We implement the mirroring in a single user environment and by visualizing a synced conversational partner in multi-user environment. We found that a realistic talking face avatar is more influential than an un-synced talking avatar or an invisible avatar.

This report presents findings from research designed to better understand how Australian audiences discover, consume, and value local children’s content in the streaming era. The Australian Children’s Television Cultures research group gathered unique, robust data through an online nationwide survey that targeted parents and carers of children aged 14 years and under. The survey was titled, “What are Your Children Watching in 2021” and ran nationally for six weeks (23 August – 3 October, 2021). A dozen extended semi-structured interviews were also carried out with select survey participants. These interviews were analysed to gain more nuanced qualitative detail to complement the quantitative survey findings. This report covers a range of key considerations, from perceptions of what makes “good” Australian children’s television, to the use of media platforms, and the importance parents and carers place on diverse representation. The report’s findings are original and provide unique insights into parents’ perspectives on Australian children’s television in the streaming era.
