Classification and Viewing System of Broadcasting Program for Cable TV

摘要

The present invention provides a CATV system, in which a cable broadcasting station system inserts and transmits information on a content level of a broadcast program between video signals of a broadcast program, and in a subscriber terminal system of the cable broadcasting station, a broadcast program inserted between the video signals. The present invention relates to a screening and viewing system for each CATV broadcasting program unit that extracts information about content ratings and compares the program content ratings with user viewing permission levels to determine whether to allow viewing. It is possible to automatically limit viewing by grades by broadcasting program unit, and even if the channel is changed frequently, the inconvenience of having to input the user grade and password every time the channel is removed is effective.
