Abstract

A technique for selectively inhibiting television receiving apparatus from displaying those television programs which satisfy predetermined content ratings criteria. Television program information associated with television programs that are receivable by the television receiving apparatus during a selected time interval, such as channel data representing the channels on which the television programs are received and rating data representing the contents of those programs, is stored. A rating code representing the content ratings criteria of those programs which a viewer wishes to inhibit from being displayed also is stored. When a desired channel is selected by the viewer, the stored rating data associated with that channel is compared with the rating code to determine if the television program transmitted on that channel satisfies the predetermined content ratings criteria. If so, the channel on which that television program is transmitted is blocked and the stored television program information associated with those television programs having rating data which do not satisfy the predetermined content ratings criteria then are displayed to permit the viewer to select an acceptable television program.

Claims

1. A method of selectively inhibiting television receiving apparatus from displaying those television programs which satisfy predetermined content ratings criteria, comprising the steps of:

storing television program information associated with television programs that are receivable by said television receiving apparatus during a selected time interval, the information associated with a respective television program including channel data representing the channel on which that program is received, title data representing the title of that program and rating data representing the content of that program;

storing a rating code representing the content ratings criteria of programs which a viewer wishes to inhibit from being displayed;

selecting a channel to display the television program that is received on the selected channel;

comparing the rating data associated with said television program that is received on said selected channel with said stored rating code to determine if said television program satisfies said predetermined content ratings criteria;

inhibiting said television receiving apparatus from displaying said television program if it is determined that said television program satisfies said predetermined content ratings criteria;

generating a list of television program information associated with those television programs currently receivable on other channels which do not satisfy said predetermined content ratings criteria; and

automatically displaying said generated list of television program information if it is determined that said television program satisfies said predetermined content ratings criteria.

2. The method of claim 1 wherein the step of storing television program information comprises transmitting from a source to said television receiving apparatus a viewing schedule of those television programs to be transmitted from said source during a predetermined time period, said viewing schedule including said channel, title and rating data of each said television program;

and storing said viewing schedule at said television receiving apparatus.

3. The method of claim 2, wherein said viewing schedule further includes start time data representing the time at which the transmission of each said television program begins;

program length data representing the duration of each said television program;

program type data representing the type of each said television program; and

program description data representing a summary of each said television program.

4. The method of claim 2 wherein said rating data represents frequency of occurrence and level of intensity of predetermined acts in said television program.

5. The method of claim 4 wherein said predetermined acts are acts of violence.

6. The method of claim 2 wherein said viewing schedule is transmitted from said source to said television receiving apparatus in a channel distinct from those channels over which said television programs are transmitted.

7. The method of claim 2 wherein said selected time interval is included within and is a submultiple of said predetermined time period.

8. The method of claim 7 wherein said selected time interval is a multiple of a half hour and said predetermined time period is a week.

9. The method of claim 1 wherein said step of storing said rating code comprises entering by a user of said television receiving apparatus a code representing predetermined acts expected in a television program and frequency of occurrence and level of intensity of said predetermined acts.

10. The method of claim 9 wherein said rating code comprises a numerical value and said rating data comprises a numerical value;

and wherein said step of comparing determines if the numerical value of said rating data exceeds the numerical data of said rating code to thereby satisfy said predetermined content ratings criteria.

11. The method of claim 1 wherein said step of generating a list of television program information associated with those television programs having rating data which do not satisfy said predetermined content ratings criteria comprises:

(a) selecting another channel, (b) comparing the rating data associated with the television program receivable on said other channel during said selected time interval to said stored rating code to determine if the television program receivable on said other channel satisfies said predetermined content rating criteria, (c) adding to a list the television program information associated with the television program receivable on said other channel if said predetermined content ratings criteria are not satisfied, and (d) repeating steps (a) through (c) until all other channels have been selected.

12. The method of claim 2 wherein an updated viewing schedule is transmitted periodically.

13. Apparatus for selectively inhibiting television receiving apparatus from displaying those television programs which satisfy predetermined content ratings criteria, comprising:

a memory for storing television program information associated with television programs that are receivable by said television receiving device during a selected time interval, the information associated with a respective television program including channel data representing the channel on which that program is received, title data representing the title of that program and rating data representing the content of that program;

means for storing a rating code representing the content ratings criteria of programs which a viewer wishes to inhibit from being displayed;

means for selecting a channel to display the television program that is received on the selected channel;

means for comparing the rating data associated with said television program that is received on said selected channel with said stored rating code to determine if said television program satisfies said predetermined content ratings criteria;

means for inhibiting said television receiving apparatus from displaying said television program if it is determined that said television program satisfies said predetermined content ratings criteria;

means for generating a list of television program information associated with those television programs currently receivable on other channels which do not satisfy said predetermined content rating criteria; and

means for automatically displaying said generated list of television program information if it is determined that said television program satisfies said predetermined content ratings criteria.

14. The apparatus of claim 13 wherein said memory is operable to store television program information transmitted from a source and further including a viewing schedule of those television programs to be transmitted from said source during a predetermined time period, said viewing schedule including said channel, title and rating data of each said television program;

said viewing schedule being stored in the memory at said television receiving device.

15. The apparatus of claim 14, wherein said viewing schedule further includes start time data representing the time at which the transmission of each said television program begins;

program length data representing the duration of each said television program;

program type data representing the type of each said television program; and

program description data representing a summary of each said television program.

16. The apparatus of claim 14 wherein said rating data represents frequency of occurrence and level of intensity of predetermined acts in said television program.

17. The apparatus of claim 16 wherein said predetermined acts are acts of violence.

18. The apparatus of claim 14 wherein said viewing schedule is transmitted from said source to said television receiving device in an out-of-band channel distinct from those channels over which said television programs are transmitted.

19. The apparatus of claim 14 wherein said selected time interval is included within and is a submultiple of said predetermined time period.

20. The apparatus of claim 19 wherein said selected time interval is a multiple of a half hour and said predetermined time period is a week.

21. The apparatus of claim 13, further comprising means for entering by a user of said television receiving device said rating code which represents predetermined acts expected in a television program and frequency of occurrence and level of intensity of said predetermined acts.
