    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

    A reliable delivery of HbbTV based Push-VoD services over DVB networks using RS codes

    International audienceHybrid broadcast broadband TV (HbbTV) is a technique providing Push-VOD services over an interactive hybrid TV. These services are broadcast using File Delivery Protocol (FDP) characterized by three levels of data representation and give rise to three loss distributions that may result in poor Forward Error Correction (FEC) recovery capabilities. In this paper, we first analyze the behaviour of the FDP protocol system over a large variety of bursty erasure channels to characterize and to understand effectively the loss patterns seen within FDP protocol and at the AL-FEC input in order to be able to dimension the AL-FEC codes. Then, we propose and investigate a novel solution based on RS AL-FEC codes for the FDP protocol to increase the robustness of HbbTV based Push-VoD services delivery over DVB networks. This paper represents a first reference work for a reliable HbbTV based Push-VOD services delivery over burst-loss channels. © 2017 IEEE
