Abstract

Video processing system having a blocking system which prevents viewing or recording of programs which exceed ratings, spending, and/or view time limits set by a supervisor who has entered a password accepted by the control system, an override system for entering instructions to temporarily override ratings, spending, and/or view time limits, and/or to permit specific programs to be viewed, and a conflict resolution system for resolving conflicts between or among multiple instructions. Related apparatus and processor are also disclosed.

Claims

1. A method for selectably controlling viewing and recording of television programs, the method comprising the steps of:

establishing at least one viewer profile for blocking images from a corresponding viewer based on limits selected from the group comprising;

program ratings, spending, channel, view time limits, time of day limits, image content ratings;

creating at least one override list including override instructions applicable to said at least one viewer profile for modifying selected ones of said limits;

detecting the existence of a conflict between override instructions; and

automatically resolving conflicts between conflicting override instructions upon detecting the existence of a conflict when said override instruction are enabled.

2. A method for controlling viewing of video images comprising the steps of:

coupling video processing circuitry to a display device so as to provide video images for display to at least one viewer;

providing parental control circuitry for blocking at least a portion of said video images from being displayed to a viewer in accordance with a corresponding viewer profile;

creating at least one override list comprising override instructions applicable to said video processing circuitry so as to unblock selected blocked video images;

detecting the existence of a conflict between override instructions; and

automatically resolving conflicts between said override instructions upon detecting the existence of a conflict when said set of limits are enabled.

3. The method of claim 2 wherein the step of resolving conflicts includes the steps of:

determining the least restrictive of conflicting override instructions; and

applying said least restrictive override instruction to said viewer profile so as to unblock at least a portion of said video images.

4. A system for selectably controlling viewing and recording of television programs, the system comprising:

at least one viewer profile establishing a set of limits for blocking images outside said limits from view;

at least one limit selected from the group comprising;

program ratings, spending, channel, view time limits, time of day limits, image content ratings;

at least one override list including at least one override instruction applicable to said at least one viewer profile for overriding at least one of said limits; and

a conflict resolver for detecting the existence of a conflict between override instructions and automatically resolving conflicts between said override instructions upon detecting the existence of a conflict when said set of limits are enabled.

5. The system of claim 4 wherein said conflict resolver is switchable between a most restrictive mode of operation and a least restrictive mode of operation.

6. The system of claim 4 including means to display to a viewer a blocking status of at least one image.

7. The system of claim 4 including at least one apparatus selected from the group comprising:

television receiver, cable box, video cassette recorder (VCR) tuner.

8. A system for selectably controlling viewing and recording of television programs, the system comprising:

at least one viewer profile establishing a set of limits for blocking images outside said limits from view of a corresponding viewer, said limits selected from the list including;

program ratings, spending, channel, view time limits, time of day limits, image content ratings;

at least one override list including override instructions applicable to said at least one viewer profile for modifying at least one of said limits;

a conflict resolver for detecting the existence of a conflict between override instructions and automatically resolving conflicts between said override instructions upon detecting the existence of a conflict when said set of limits are enabled.

9. The system of claim 8 wherein said conflict resolver is switchable between a least restrictive mode of operation and a most restrictive mode of operation, wherein the least restrictive of conflicting override instructions is applied to said viewer profile when said conflict resolver is in said first mode of operation and the most restrictive of conflicting override instructions is applied to said viewer profile when said conflict resolver is in said second mode of operation.

10. The system of claim 8 wherein said images blocked from view in accordance with said profile are selected from the group comprising:

programs, channels, program rating, scene ratings, spending limits, time limits and time period.

11. The system of claim 8 wherein said images unblocked in accordance with said override list are selected from the group comprising:

programs, channels, program rating, scene ratings, spending limits, time limits and time period.

12. A system comprising:

a video signal processing apparatus for producing an output signal suitable for coupling to a display device to produce images for viewing or recording;

a blocking system coupled to said video signal processing apparatus which blocks said images in accordance with a profile set by a supervisor, said blocking system including;

at least one override list applicable to said profile such that images blocked in accordance with said profile are unblocked in accordance with said override list; and

a conflict resolver for detecting the existence of a conflict between override instructions and automatically resolving conflicts between two or more of said override lists upon detecting the existence of a conflict.

13. The system of claim 12 wherein said conflict resolver includes at least first and second conflict resolution modes.

14. The system of claim 13 wherein said first conflict resolution mode is a least restrictive mode and said second conflict resolution mode is a most restrictive conflict resolution mode.
