가상화 기반의 상황인지형 텔레스크린 서비스 플랫폼

Abstract

At the early stage of the Digital Signage, its service has been limited to provide text-based simple information or one way advertisement. Recently, along with the improvement of the terminal performance and the deployment of smart devices, the demand for interactive communication and high-performance service has been increased. However, it is not easy for the digital signage with a conventional structure to provide user-responsive or smart device interworking tele-screen services. Furthermore, the conventional structure is hard to support low-end terminal devices to provide high-performance services. And the dependency to implementation factors such as OS, hardware specification or platform middleware makes the system difficult to be deployed widely. In this paper, we propose an environment-aware tele-screen platform architecture based on virtualization technologies. The implemented system based on the proposed platform architecture can provide environment-aware tele-screen services by collecting and analyzing the state information of users and circumstances utilizing camera, NFC(Near Field Communication), various sensors, smart phones, etc. Also by applying virtualization technology, the total cost of ownership is reduced and the high-performance interactive services such as 3D rendering contents can be provided with low-cost tele-screen terminals.
