We have developed the Nod Generation Internet Server (NGIS) which has Network-Storage (NS) Cards for streaming service. The NGIS system provides assets of various types to support streaming service and has NS Cards with a powerful network function. The NGIS system offers streaming service for assets of various types such as MPEG 1 files, MPEG 2 files and MPEG 4 files. In this paper we purpose the method of installing assets, such as MPEG 1 files, APEG 2 files and APEG 4 files, to support to streaming service in the NGIS system. If the type of multimedia data is MEG 1 or 2, we propose the method of installing assets, which makes Fast Forward (FF) files and Fast Rewind (FR) files in real-time in order to support a FF service and a FR service, and suggest another metW which makes a FF file and a FR file off line and installs the FF file and the FR file when system of installing assets begins. In this paper also we purpose Contents Management System (CMS) calling asset installer automatically to install assets when the assets am at a certain place.
