发明名称 Video player having a two part module that allows an authorized person, such as a parent, to set an amount of time for which the video can be watched, after which it will automatically switch off thus limiting viewing time
摘要 Video player has a module of two parts that are both required for the video to play. A first part (3b) is connected to the video so that it cannot be removed by an authorized person. The second, portable, part (3a) is connected to the first via a signal connection (S/E). It has a timer that is protected against unauthorized use that allows a user time to be set after which the video switches off.
