With an increasing number of users having more than one smart device, an environment for delivering the same content through multiple devices has been established via wired and wireless network connections. Consequently, online education services that have provided content on one device screen by dividing it into multi pieces have changed to providing it through more than one smart device using a synchronization system embedded in a content viewer application or an e-book reader. However, most existing content viewers do not support content synchronization. Some do support it, but are platform-dependent. To address these shortcomings, we propose a synchronization system embedded in an educational content viewer that supports a wide range of content types and is platform-independent. To examine the performance of the proposed synchronization system, we conducted experiments on processing time for synchronization by applying it with different network connection types and between smart devices with different operating systems (OSs). The synchronization system performed within a reasonable time on wireless (Wi-Fi) and long-term evolution (LTE) networks, and most of the content, except three dimensional (3D) objects, synchronized in real-time regardless of OS type.
