Abstract
The URLs and priority levels of a plurality of frequently accessed sites are stored beforehand in a user registration table in a communication channel switch. The communication channel switch stores the start time and end time of the latest access and the elapsed time at the site, in an access history table. The communication channel switch changes the priority levels in the user registration table in accordance with the length of the elapsed time. The communication channel switch collects video data from the sites prior to the time recorded as the latest access start time in the access history table, in accordance with the priority level in the user registration table, and stores the video data in a storage unit in the switch. When the user accesses a site included in the user registration table, the communication channel switch provides the site information in the storage unit quickly.
