Periodic Report Summary 1 - CLOUDSCREENS (Support of cloud services for multimedia delivery and consumption)

Cloud technology has gone through a tremendous development over the last few years, offering important benefits to their users. Many people use clouds on daily basis (without even realizing that they do so) with services such as web-based e-mail or social networks. Clouds are primarily platforms that allow execution in various forms across multiple resources. The different types of clouds have in common that they (directly or indirectly) enhance resources and services with additional capabilities related to manageability, elasticity and system platform independence. Several business models rapidly evolved to exploit this technology by providing software applications, platforms, data-storage, infrastructure and other hardware as services. The interrelations of these components have been ambiguous and the feasibility of enabling their interoperability has been debatable. Main questions still arise concerning data handling, security and multi-tenancy.

The main research objective of the CLOUDSCREENS project is to research new topics that will contribute to the creation of future software-based services that exploit the cloud technology for the enabling of next generation advanced multimedia-based services. The project will focus on four interconnected topics: service quality and capacity enhancement in multi-service environments via efficient high volume multimedia delivery, creation of personal spaces and smart environments, and realising new generation of user interfaces taking speech as input, through which user privacy preservation is maintained at a time when cybersecurity concerns are rising. The research on these advanced multimedia-based services will benefit the vast computing and networking resources provided by the cloud to enable the easy deployment of them.

The first research objective of the project is to design a mediation entity that is responsible to manage the user-side media resources and the network capabilities and that can act as a mediator between the client application and multiple clouds. In particular, this mediation entity will be capable of compressing very high volume, Ultra High Definition and high dynamic range video signals using perception-inspired techniques for efficient delivery over the networks, and thus will be able to manage resource and capability balance.

The second research objective is to design a generic cloud service that is responsible for realizing personal spaces in a multi-user environment that can be used for providing a highly personalized multimedia usage environment. In particular, this is where personal spaces will be created with no physical boundaries by advancing the spatial audio rendering technology. In this way, multiple users in the same environment can enjoy their own personal audio zones.

The third research objective is to develop a cloud service that, through negotiation with a managing entity inside the user environment, is capable of enhancing delivery of the primary multimedia services.

The fourth research objective of the project is to design a user interface that runs as a cloud service, which accepts natural speech as input with a built-in mechanism for protection of user privacy in the wake of ever increasing cybersecurity threats. It is intended to preserve the user privacy through anonymising the user data acquired from multiple connected smart input devices as well as user interfaces (such as speech) using signal processing techniques, without affecting the usefulness of the data for a vast range of Internet-based services.

The goal of this project is to provide high quality training to the ESRs through a diverse set of training events including on-job research training, personal skills development and career development. During this training the ESRs will be exposed to the state-of-the art techniques for researching into cloud services for multimedia delivery and consumption. This will also entail familiarising themselves with the available technologies in multimedia coding, processing, and communications systems. The training programme is realized by an international, inter-sectoral consortium. Being exposed to academic as well as industrial environments early in their careers will help the ESRs make informed career choices, will increase their attractiveness to the private sector, and strengthen the relationship between the industry and the academia. Each ESR has a well-defined individual project and will be part of a group of outstanding European researchers with a high level of employability and with great exposure to researchers in and outside the specific expertise field of cloud computing.

The project shall result in the design of various complex multimedia processing and analysis suits that will be supported by the cloud computing to help the creation of boundary-free personal spaces, protection of user privacy in smart and connected environments particularly during user interfacing, the efficient delivery of very high volume multimedia data. The overall outcome of the project is a scientific contribution to the creation of future multimedia-based services that exploit the cloud-based services.
