System and method for selectively de-scrambling media signals |
摘要 |
A system and method for selectively de-scrambling a media signal is presented. A user enters control settings into a content receiver whereby the control settings correspond to a particular viewer or a particular time-of-day. The content receiver receives a media signal and metadata that includes censorship level information. The content receiver uses the control settings to identify an applicable censorship level and uses the metadata to de-scramble the media signal to a censorship level corresponding to the identified applicable censorship level. The content receiver provides the de-scrambled media signal to a viewer's display.
