Content sharing mechanism with multiple devices in real-time multimedia service environment

This paper presents a mechanism of content sharing for multiple devices in real-time multimedia service environment and analyzes the CPU performance of the contents transformation server. In this environment, users are provided the transformed multimedia contents adequate to their devices. Our existing structure of transforming service is not designed to sharing the content with multiple users using a same type of devices. So, the CPU usage ratio becomes higher, even though many devices with same type connect to the transforming server. Experimental results show that the CPU usage ratio of content sharing mechanism for three users is improved over 50% compared to that of the environment without sharing content1.
