MediaSync: Handbook on Multimedia Synchronization

This book provides an approachable overview of the most recent advances in the fascinating field of media synchronization (mediasync), gathering contributions from the most representative and influential experts. Understanding the challenges of this field in the current multi-sensory, multi-device, and multi-protocol world is not an easy task. The book revisits the foundations of mediasync, including theoretical frameworks and models, highlights ongoing research efforts, like hybrid broadband broadcast (HBB) delivery and users' perception modeling (i.e., Quality of Experience or QoE), and paves the way for the future (e.g., towards the deployment of multi-sensory and ultra-realistic experiences). Although many advances around mediasync have been devised and deployed, this area of research is getting renewed attention to overcome remaining challenges in the next-generation (heterogeneous and ubiquitous) media ecosystem. Given the significant advances in this research area, its current relevance and the multiple disciplines it involves, the availability of a reference book on mediasync becomes necessary. This book fills the gap in this context. In particular, it addresses key aspects and reviews the most relevant contributions within the mediasync research space, from different perspectives. Mediasync: Handbook on Multimedia Synchronization is the perfect companion for scholars and practitioners that want to acquire strong knowledge about this research area, and also approach the challenges behind ensuring the best mediated experiences, by providing the adequate synchronization between the media elements that constitute these experiences

The specification and design of a prototype 2-D MPEG-4 authoring tool

The purpose of this project was the specification, design and implementation of a prototype 2-D MPEG-4 authoring tool. A literature study was conducted of the MPEG-4 standard and multimedia authoring tools to determine the specification and design of a prototype 2- D MPEG-4 authoring tool. The specification and design was used as a basis for the implementation of a prototype 2-D MPEG-4 authoring tool that complies with the Complete 2-D Scene Graph Profile. The need for research into MPEG-4 authoring tools arose from the reported lack of knowledge of the MPEG-4 standard and the limited implementations of MPEG-4 authoring tools available to content authors. In order for MPEG-4 to reach its full potential, it will require authoring tools and content players that satisfy the needs of its users. The theoretical component of this dissertation included a literature study of the MPEG-4 standard and an investigation of relevant multimedia authoring systems. MPEG-4 was introduced as a standard that allows for the creation and streaming of interactive multimedia content at variable bit rates over high and low bandwidth connections. The requirements for the prototype 2-D MPEG-4 authoring system were documented and a prototype system satisfying the requirements was designed, implemented and evaluated. The evaluation of the prototype system showed that the system successfully satisfied all its requirements and that it provides the user with an easy to use and intuitive authoring tool. MPEG-4 has the potential to satisfy the increasing demand for innovative multimedia content on low bandwidth networks, including the Internet and mobile networks, as well as the need expressed by users to interact with multimedia content. This dissertation makes an important contribution to the understanding of the MPEG-4 standard, its functionality and the design of a 2-D MPEG-4 Authoring tool. Keywords: MPEG-4; MPEG-4 authoring; Binary Format for Scenes

DLNA test suite

Mestrado em Engenharia Electrónica e TelecomunicaçõesH a uma tendencia para o crescimento da inteleg^encia nas nossas casas. Normas como UPnP e DLNA prop^oem automatizar a forma como os nossos dispositivos interagem. No quadro actual, os dispositivos de media dominam a intelig^encia das nossas casas. O f orum UPnP e uma iniciativa industrial criada para permitir a conectividade f acil e robusta entre dispositivos auto-su cientes e PC's de diferentes fabricantes. O objectivo deste f orum e desenvolver normas para descrever os protocolos de comunica c~ao entre dispositivos e esquemas XML, e permitir a opera c~ao entre dispositivos numa rede escal avel. O DLNA foi criado em Junho de 2003 com o nome Digital Home Working Group (DHWG), em Junho de 2004 foi alterado para Digital Living Network Alliance (DLNA). A alian ca DLNA e liderada por 23 companhias (Access, Awox, Broadcom, Cisco, Comcast, HP, Huawei, IBM, Intel, Kenwood, LG Electronics, Macrovision, Microsoft, Motorola, Nokia, NXP Semiconductors, Panasonic, Philips, Pioneer, Samsung, Sharp, Sony e Toshiba) e tem mais de 245 membros. Hoje em dia os consumidores est~ao a adquirir, ver e gerir uma grande quantidade de informa c~ao digital (fotos, m usica e v deos) nos seus PCs, dispositivos electr onicos e dispositivos m oveis. Estes pretendem aceder de forma f acil a partir de qualquer dispositivo em qualquer parte da sua casa aos seus conte udos de outros dispositivos. Esta ideia e poss vel atrav es da cria c~ao de uma rede com dispositivos certi cados pela alian ca DLNA. Uma rede DLNA oferece aos consumidores inter-conectividade autom atica entre equipamentos dom esticos, e aos fabricantes uma oportunidade de inovar e de diferenciar os seus produtos. Do ponto de vista do operador, aumenta a capacidade de diagn ostico e gest~ao remota da rede de cliente.The world we live on is becoming more and more digital, our homes are growing in intelligence. Standards like DLNA and UPnP AV propose to exchange our digital media (photos, audio, video) in an automatic way. The UPnP forum is a industrial initiative created to allow easy connectivity and robustness between independent devices from di erent fabricators. The objective of this forum is to develop templates to discriminate the protocols and XML schemes involved in the process of interoperability in a scalable network.
