ITV services for socializing in public places

Watching TV in public locations is very different from watching at Home, but it can also be a worthy experience, especially in the context of certain collective events, such as live football. The increasingly rich features of iTV services may even provide the ground for making the Television infrastructure an alternative framework for the deployment of public display services. In this paper, we present and discuss integration scenarios in which the iTV infrastructure and public display services conceived for multi-user interaction in public spaces are combined to generate new types of services offer. It reveals a considerable potential on the idea of leveraging iTV infrastructures for supporting new types of public display services benefiting from content generated and social interactions of the co-located audience. The successful use of these approaches will require a clear understanding of the properties of the iTV infrastructure and a focus on the type of applications in which those properties may provide more added-value than limitations.(undefined

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

Supporting Relationships with Video Chat

Video chat is often called the “closest thing to being there”, but anyone who has used video chat to maintain personal relationships or collaborate with others knows that video chat is not the same as face-to-face interaction. In this thesis, I focus on understanding how video chat can be most effectively designed and used to support relationships, helping to bridge the communication gap for distance separated people. An important difference between video chat and face-to-face interaction is potential effects of seeing oneself. In this thesis, I present two studies exploring this important caveat to supporting relationships remotely. The first study shows that the dominant interface design (which shows one’s own video feed) has measurable effects on people’s experiences and conversations in VMC. The second study focuses on a specific group of people—those with social anxiety—who may be particularly affected by self-view in video chat interfaces. This study shows that interfaces that focus on content (much like the media sharing system presented in this thesis) have the potential to minimize effects of feedback in video chat. Another key difference between video chat and face-to-face interaction is the difficulty of engaging in shared activities. Colocated friends or family members can easily share activities such as walks, movies, or board games; distance separated people have a much harder time doing the same. The work presented in this thesis introduces a synchronous media sharing system that can serve as a powerful tool for maintaining relationships. Building on this work, I show that synchronous media sharing is also useful for creating new relationships as well. Together, the system and studies presented in this thesis provide valuable new insights and techniques for the development of video chat tools that support new and sustained relationships over a distance
