A consideration on contents management systems using quality transition mode in video contents utilization services by on-demand

Video contents service over a network is expanded by improvement in network speed and large capacity in recent years. Meanwhile, when users use a lot of contents, they are faced with the problem of the lack of memory capacity. Therefore, the contents management methods are important for the services. Then, we had proposed the management method using cache delivery and scalable contents. In this study, after a content utilization service model using mobile and home terminal is defined, we propose a management method using the data transition process of scalable structure. This is based on elapsed time and its content quality. We consider the efficiency in this model from a viewpoint of single quality and the quality of two.
