OPERATION CONTROL DEVICE, OPERATION CONTROL METHOD, LICENSE PROVISION SYSTEM, OPERATION CONTROL PROGRAM, AND RECORDING MEDIUM

摘要

Provided is a license server (400) that controls user terminals (100) on the basis of licenses that allow one user terminal (100) to play any content and other user terminals (100) to only play content that is the same as the content being played on the aforementioned user terminal (100). A service usage status change detection unit (411) detects when the content being played on the user terminal (100) that can play any content changes. When a change is detected, a license rights control unit (412) changes the content that the other user terminals (100) can play to the content being played on the user terminal (100) that can play any content.
