In this paper, we describe a continuous media storage system that supports the constant frame rate retrieval with variable bit rate streams. The novel characteristics of our storage system is the followings. The utilization of disk bandwidth is higher than traditional continuous media storage systems since the admission test of our storage system adopts average bandwidth usages of respective streams by introducing a novel media scaling technique in order to avoid degrading the quality of a media stream significantly when the total bandwidth exceeds 100%. Our storage system takes into account dynamic QOS control schemes. Also, it controls QOS values of respective streams according to their contents. First, we describe a media scaling technique for realizing the above characteristics, and present its scheduling algorithm and disk layout policy. Also, we present some results demonstrating the effectiveness of our approach.
