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

Actas de las XIV Jornadas de Ingeniería Telemática (JITEL 2019) Zaragoza (España) 22-24 de octubre de 2019

En esta ocasión, es la ciudad de Zaragoza la encargada de servir de anfitriona a las XIV Jornadas de Ingeniería Telemática (JITEL 2019), que se celebrarán del 22 al 24 de octubre de 2019. Las Jornadas de Ingeniería Telemática (JITEL), organizadas por la Asociación de Telemática (ATEL), constituyen un foro propicio de reunión, debate y divulgación para los grupos que imparten docencia e investigan en temas relacionados con las redes y los servicios telemáticos. Con la organización de este evento se pretende fomentar, por un lado el intercambio de experiencias y resultados, además de la comunicación y cooperación entre los grupos de investigación que trabajan en temas relacionados con la telemática. En paralelo a las tradicionales sesiones que caracterizan los congresos científicos, se desea potenciar actividades más abiertas, que estimulen el intercambio de ideas entre los investigadores experimentados y los noveles, así como la creación de vínculos y puntos de encuentro entre los diferentes grupos o equipos de investigación. Para ello, además de invitar a personas relevantes en los campos correspondientes, se van a incluir sesiones de presentación y debate de las líneas y proyectos activos de los mencionados equipos

Application of AL-FEC to HbbTV DVB-T2 Systems for the Provision of VoD Services in Portable and Fixed TV Reception

International audienceInteractive TV services have grown significantly in recent years thanks to the standardization of several approaches such as Hybrid broadcast and broadband TV (HhhTV) technology. HbbTV applied to portable and fixed DVB-T2 reception, allows TV channels broadcast via terrestrial channels to publish interactive applications in addition to their TV programs. Video-On-Demand (VoD) provided via Push-VoD service, represents one of these applications. However the provision of HhhTV Push-VoD services in portable and fixed DVB-T2 reception is challenged by severe propagation conditions of the static multipath scenarios. In this paper, we provide a first reference addressing the question of how HbbTV DVB-T2 systems enables a reliable delivery of Push-VoD services in portable and fixed broadcast reception, in absence of broadband networks. We analyze the coexistence of HbbTV standard and DVB-T2 standard. We investigate the solution based on the LDPC-Staircase AL-FEC scheme for improving the portable and fixed broadcast reception of Push-VoD service in HbbTV DVB-T2 systems. Simulation results show that LDPC-Staircase AL-FEC code enables to enhance the delivery of HbbTV Push-VoD services over DVB-T2 systems with portable and fixed TV reception
