A continuous playing scheme on RESTful web service

Currently, the paradigm shift in our computing is dramatically moving from PC to mobile devices and many new services are emerging based on the development of broadband network and hardware technologies such as Cloud computing and Web of things. Especially, the popularity of smart devices has increased the demand for sharing multimedia contents at anywhere and on any of user devices with seamless display. In this paper, we introduce a prototype implementation of contents sharing service working on different devices with seamless connectivity. The purpose is that the proposed system allows users to share their media contents and play them continuously regardless of the situation of switching from one device to another. For example, N-screen services allow users to manage their active sessions among multiple devices having different capabilities and architectures. The system implemented has the basic sharing configuration of three devices: PC, Smartphone, and Tablets, and utilize an Open Service Platform based on RESTful Web Services. The prototype was successfully implemented and its performance was simulated with sample 3D videos with different file sizes to estimate load latencies while switching from one device to another. The result shows the feasibility of contents sharing system based on RESTful Web Services with low latency on Smartphone.
