No. of bitstreams: 1 Marco Antonio Camargo Nascimento.pdf: 5611314 bytes, checksum: 26a9d237701a4797ffb4626733644db3 (MD5) Previous issue date: 2016-11-30 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Since the end of 2010, news programs have no longer been watched as they used to be. TV is in real time on the Internet, computers, laptops, tablets and mobile phones. In the era of digital convergence, viewers do not only watch TV, but they concomitantly access the content from live images or on demand. This work aims to analyze the codes of this image culture since the beginning of television in Brazil and to analyze the changes undergone by the advent of social media. It also intends to point out the affinity between the nature of the accelerated images and which are out of control of this online media generation with the nature of the images portrayed by the German thinker Aby Warburg. The research corpus comprises an image cut of the period in which the media revolution has resulted in a new language. The hypothesis is that TV, almost seven decades later, must be understood as a broadcasting language, from which it originated, and as a new product of media visibility resulting from the advent of social media. Television has, for the first time, lost its supremacy to the Internet and needed to establish new patterns of relationship with viewers. The work aims to demonstrate the phenomenon of this change and it is based on studies and research on journalism, television and image, particularly those involving technology and thinkers on the image culture. It makes a parallel with the German thinker Aby Warburg, whose theory has characteristics of the language disseminated in the digital communication culture. The scientific research of this study allowed to conclude that TV has been in conflict with the social network as Hercules had been with Hydra. Journalism, which has the news as its major symbolic value, means tactile, volatile and shared mediation of this conflict / Desde o ano 2010 os telejornais não são mais assistidos como antigamente. A TV está em tempo real na Internet, nos computadores, notebooks, tablets e celulares. Na era da convergência digital, os espectadores já não assistem somente à TV, mas acessam instantaneamente o conteúdo de imagens ao vivo ou on demand. Este trabalho tem como objetivo analisar os códigos desta cultura da imagem desde o início da televisão no Brasil, bem como as mudanças sofridas com o advento das redes sociais. Pretende-se também assinalar a afinidade entre a natureza das imagens aceleradas e fora de controle da geração online media com a índole das imagens retratadas pelo pensador alemão Aby Warburg. O corpus da pesquisa compreende um recorte da imagem no período em que a revolução dos meios resultou em uma nova linguagem. A hipótese é a de que a TV, quase sete décadas depois, deve ser compreendida como linguagem broadcasting, da qual se originou, e como um novo produto da sociedade midiática, resultante do advento das redes sociais. A televisão pela primeira vez perdeu a supremacia para a Internet e precisou estabelecer novos padrões de relacionamento com os telespectadores. O trabalho pretende demonstrar o fenômeno desta mudança e ampara-se em estudos e pesquisas sobre jornalismo, televisão e imagem, notadamente aqueles envolvendo tecnologias e pensadores da cultura da imagem. Faz um paralelo com o pensador alemão Aby Warburg, cuja teoria possui características da linguagem disseminada na cultura da comunicação digital. A pesquisa científica deste trabalho permitiu concluir que a televisão vive um conflito com a rede social como Hércules viveu com a Hidra. O jornalismo, cujo maior valor simbólico é a notícia, significa a mediação tátil, volátil e compartilhada deste conflito

Although Set-top-Boxes(STBs) are widely deployed today to connect a media source to a display (traditionally a television set), the market is changing due to the introduction of Internet Protocol Television, Over-the-Top streaming devices, gaming console, home theater Personal Computer, smart TV, etc. There is an evolving concept of a Home Media Center (HMC). This HMC provides consumers with an integrated home media environment and experience. This thesis explores the transition from STBs to HMCs. The specific questions that this thesis project answers are: What will a future HMC look like? What will its functions be? What interfaces and protocols will it use? Who will make these HMCs?  How can STB vendors evolve to be HMC vendors or will they simply cease to exist?  This thesis project designed and evaluated a hypothetical HMC prototype based upon current technology trends and user expectations. This prototype was used with 68 volunteers to identify and prioritize the most important features that a HMC should provide. Based upon the most important of these features a conceptual HMC prototype is designed to define a HMC product roadmap for 1, 3, and 5 years. This roadmap is used to project the economic impact of HMCs on the current STB industry.  This economic analysis considers Sweden as the target market. This thesis could be used by current STB vendors to define their own company specific roadmaps to support their transition to the future HMC market. / Aven digitalboxar är spridda i dag för att ansluta en mediakälla till en bildskärm (traditionellt en TV) är marknaden förändras på grund av införandet av Internet Protocol Television, Over-the-Top streaming anordningar, spelkonsol, hem teater Personal Computer, smarta TV osv. Det finns en framväxande begreppet Home Media Center (HMC). Detta HMC ger konsumenterna ett integrerat hem mediemiljö och erfarenhet. Denna avhandling utforskar övergången från digitalboxar till HMC. De specifika frågor som detta examensarbete skall besvara är: Vad kommer en framtida HMC se ut? Hur kommer dess funktioner att bli? Vilka gränssnitt och protokoll kommer den att använda? Vem kommer att göra dessa HMC? Hur kan digitalboxar leverantörer utvecklas vara HMC säljare eller kommer de helt enkelt att upphöra att existera? Detta examensarbete designar och utvärderar en hypotetisk HMC prototyp baserad på nuvarande tekniktrender som användarnas förväntningar studie. Denna prototyp användes med 68 frivilliga att identifiera och prioritera de viktigaste funktionerna som en HMC bör ge. Baserat på de viktigaste av dessa funktioner en konceptuell HMC prototyp kommer att utformas för att definiera en HMC produkt färdplan för en, 3 och 5 år. Färdplanen kommer att användas för att projicera de ekonomiska konsekvenserna av HMC på den aktuella digitalboxar industrin. Denna ekonomiska analysen kommer att överväga Sverige som målgrupp. Denna avhandling kan användas av nuvarande digitalboxar leverantörer för att definiera sina egna företagsspecifika färdplaner för att stödja övergången till den framtida HMC marknaden.

Téma doktorské práce je zaměřeno na analýzu zpracování signálů v širokopásmových multimediálních sítích a systémech budoucnosti, kde se předpokládají systémy s ultra vysokým rozlišením (UHDTV), vysokým snímkovým kmitočtem (HFR) a stereoskopické systémy (3D). Tyto systémy budou umožňovat vysoce účinnou zdrojovou kompresi obrazu, zvuku a dat a také jejich vysoce účinný přenos, a to jak při volném vysílání (např. DVB-T2), tak ve službách placené televize (např. IPTV). Cílem práce je analýza a vyhodnocení kvality obrazu a služeb v těchto systémech na základě objektivních metrik a subjektivních testů. Práce se dále zaměřuje na analýzu vnímané kvality u stereoskopické televize, kódovací účinnost moderních stereoskopických enkoderů a vlivu sekvencí na uživatelský komfort.

This semestral thesis describes the possibilities of source coding videos, the attributes of the videos and their recommended changes for test. Subjective methods of scores of quality and their division into metrics with references and without references are delineated. In this work, a draft of videos for test of comparison of set metrics is specified here. Further, the coding and options of attributes of videosequences for scoring of the quality of the picture is presented. The displaying system is described and quazicrowdsorcing system of collecting the datas was created.
