METHOD FOR MANAGING VIEWING OF A PARTICULAR CONTENT RECORDED ON AN INFORMATION RECORDING MEDIUM

摘要

A DVD player (11) reads disc control information recorded on a DVD medium (M) and causes a display (12) to display a start menu screen, thereby prompting a viewer to perform authentication ([1]). The viewer uses a remote controller (11a) to display a first viewer authentication screen ([2]). Then, an acquisition code is indicated and an input of a password is requested. Here, the viewer uses a mobile telephone (13) to access the Web site indicated by URL shown on the first viewer authentication screen (substantially, a server computer (2)) and input a user ID and an acquisition code, thereby acquiring a password required for viewing the content of the DVD medium (M) ([3] and [4]). The viewer inputs the acquired password into the viewer authentication screen (5). While a program recorded on the DVD medium (M) is executed, the DVD player (11) authenticates the password which has been input. If the password is judged to be valid, reproduction of the specified content is started.
