Nowadays, multimedia is becoming an important part of our live. Every day, the number of people that are having multimedia experiences is augmenting. To allow this growth in multimedia experiences, a new set of devices has been developed. Each of those devices has different terminal and network capabilities, or even different functionalities. As a result of this growing variety of devices, more and more people tend to use several devices for multimedia consumption. Having a wide set of devices for multimedia experiences, results in a demand for seamless switching between devices, better known as session mobility. In this paper, we discuss how session mobility can be realized between heterogeneous devices using MPEG-21 technology. First, we give an overview of the difficulties that occur when doing session mobility between heterogeneous devices. After this problem statement, we give a detailed discussion on how to overcome those difficulties by using MPEG-21. Throughout this paper, we will demonstrate how different parts of MPEG-21 can be integrated into a complete MPEG-21 compliant multimedia framework that facilitates session mobility between heterogeneous devices. |
