Abstract
In a system for reproducing AV information from a recording medium, such as a DVD, not only are usual titles reproduced, but also related information relevant to specific stream information is acquired easily by making use of resources on a computer network. In a reproducing system with the function of reproducing the title information recorded on a DVD and displaying it on the screen of a display section, when the user clicks a Web mark on the screen, the CPU links to a Web server on the Internet via a modem and accesses the Web page related to the stream information on the screen. At that time, the related Web page is the selected information conforming to parental information, or attribute information, set in the system.
