In order to provide a system and method for providing a service through a video router that is a network resource, connection and disconnection of a service is performed through an ATM switch 5, and transmission of video traffic is performed by the video router 6 in the ATM switch 5. In the system configured to perform through the method and the method applied to the system, if the video desired by the subscriber exists in the video buffer 4, the video service is provided directly to the subscriber, and if the video is not stored in the video buffer 4, the stored video A first step 201 to 215 of searching for a service and providing a service through the video router 6; A second step (216 to 212) for determining a new popularity rank if there is a change in popularity rank; And a third step (301 to 305) of allocating a new channel or copying and allocating a new channel to a subscriber after searching for a service channel, thereby providing efficient on-demand and economical services. .
