Selectively de-scrambling media signals
View Patent ↗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.
1. A method of user-controlled censoring of a media signal, said method comprising:
receiving the media signal for a single television program, the media signal including first censorship level data and second censorship level data, the first censorship level data including a first set of pixel numbers for a specific frame included in the single television program and the second censorship level data including a second set of pixel numbers for the specific frame included in the single television program, wherein the first set of pixel numbers are different than the second set of pixel numbers;
retrieving control settings from a storage area;
identifying an applicable censorship level using the retrieved control settings;
selecting either the first censorship level data or the second censorship level data based upon the identified applicable censorship level;
in response to selecting the first censorship level data, selecting the first set of pixel numbers and de-scrambling pixels within the specific frame that correspond to the first set of pixel numbers;
in response to selecting the second censorship level data, selecting the second set of pixel numbers and de-scrambling pixels within the specific frame that correspond to the second set of pixel numbers; and
displaying the frame with the de-scrambled pixels.
2. The method as described in claim 1 wherein the control settings are configured prior to receiving the media signal, the configuring further comprising:
receiving a user request;
authenticating the user request;
receiving the control settings in response to the authentication; and
storing the control settings in the storage area.
