Abstract The past decade has witnessed a significant increase in the research efforts around the Quality of Experience (QoE) which is generally referred to as a human-centric paradigm for the Quality of a Service (QoS) as perceived by the (end) user. As it puts the end user in the center stage, it may have various dimensions and one dimension recently gained momentum is 3D video. Another dimension aims at going beyond 3D and promises advanced user experience through sensory effects. This is a novel approach for increasing the user experience – beyond 3D – through sensory effects. The motivation behind this work is that the consumption of multimedia assets may stimulate also other senses than hearing or vision, e.g., olfaction, mechanoreception, equilibrioception, or thermoception that shall lead to an enhanced, unique user experience. This could be achieved by annotating the media resources with metadata (currently defined by ISO/MPEG as part of the MPEG-V standard) providing so-called sensory effects that steer appropriate devices capable of rendering these effects (e.g., fans, vibration chairs, ambient lights, perfumer, water sprayers, fog machines, etc.). In particular, we will review the concepts and details of the forthcoming MPEG-V standard and present our prototype architecture for the generation, transport, decoding and use of sensory effects. Furthermore, we will present details and results of a series of formal subjective quality assessments which confirm that the concept of sensory effects is a vital tool for enhancing the user experience.

Abstract Vehicular Ad Hoc Networks (VANETs) are the first practical step towards the deployment of urban ad hoc networks. WiFi enabled smart devices will provide the first platform for a field deployment of vehicular applications and protocols. At the beginning safety and navigation applications will open the market but as the deployment will expand games and multimedia entertainment will lead the road. Early applications are likely to use simple vehicle-to-vehicle content dissemination protocols, or one-hop vehicle-to-infrastructure networking. However, multi-hop routing protocols for these vehicular networks will be feasible as the density of devices increases. These networks can be characterized as being highly mobile with frequent partitioning. A major challenge is that many existing routing protocols have difficulty discovering and maintain routes in such environments. Similarly, current transport level protocols as well as user applications are not designed for such harsh environment and a partial redesign is necessary to operate in-vehicle. This talk introduces the challenges and opportunities of multimedia vehicular networks in urban areas. In particular we will analyze the role of mobility, the propagation, the routing on multimedia VANET applications.
