This thesis intends to suggest how to produce adaptable contents that can be replayed on a device by extracting web contents in order that an existing web page can be replayed by using a device that can replay multimedia technology such as mobile and TV. To perform a service by using MobileGate system and adaptively converting one HTML page existing on web to a device, a page defined as DIDL in MPEG-21 is used. To use numerous amount of web contents in a device having a limited interface, by extracting a contents through DFS method, Circular Doubly-Linked List is established and served. DIDL of average 18 pages to minimize scroll in one web page is generated and all contents on web can be approached and replayed by only up and down button. In this research, web contents service that can be offered by using PC can be offered from mobile and TV device that are under ubiquitous environment.
