Apparatus and method of selecting video programs based on viewers' preferences

1. A method for selecting audiovisual programs for presentation to a viewer, each of the audiovisual programs having a plurality of program attributes and a corresponding content code comprising a plurality of information fields representing the plurality of program attributes of the audiovisual program, comprising the steps of:

storing a viewer preference file, wherein said viewer preference file comprises a plurality of attribute ratings corresponding to the plurality of program attributes, wherein each of said attribute ratings represents the viewer's preference of the program attribute corresponding to said rating;

for a plurality of the audiovisual programs, receiving a plurality of the corresponding content codes;

for each of said received content codes, comparing said viewer preference file to said corresponding content code such that each of said viewer's attribute ratings is compared with the corresponding information field in said corresponding content code; and

in response to said comparing step, selecting at least one of the plurality of audiovisual programs for presentation to the viewer.

2. The method of claim 1 and further comprising the step of updating said viewer preference file.

3. The method of claim 2 and further comprising the steps of:

displaying a predetermined audiovisual program to a viewer; and

receiving ratings from the viewer corresponding to the attributes for said predetermined audiovisual program, before said updating step.

4. The method of claim 2 and further comprising the steps of:

storing a plurality of preferred audiovisual programs in a list in response to performing a plurality of said selecting steps;

displaying said preferred list of audiovisual programs to a viewer; and

soliciting a ranking from the viewer for each of said preferred list of audiovisual programs, before said updating step.

5. The method of claim 1 wherein the corresponding content codes and said viewer preference files each comprise corresponding fields of the attributes, and wherein step of comparing comprises the steps of:

multiplying fields of a predetermined content code with corresponding fields of said viewer preference file to obtain a plurality of products;

applying said plurality of products to a neural network; and

determining a grade corresponding to said predetermined content code based on said products.

6. The method of claim 5 and further comprising the steps of:

performing said multiplying, applying, and determining steps for a plurality of content codes to obtain a plurality of corresponding grades;

choosing a subset of said plurality of corresponding grades based on the relative magnitudes of said grades; and

storing a preferred list of audiovisual programs corresponding to said grades in response to said choosing step.

7. The method of claim 6 and further comprising the steps of:

displaying said preferred list of audiovisual programs to a viewer; and

soliciting a ranking from the viewer for each of said preferred list of audiovisual programs.

8. The method of claim 7 and further comprising the step of updating said viewer preference file in response to said soliciting step.

9. The method of claim 5 wherein said neural network comprises weighing factors, and further comprising the steps of:

receiving updated viewer preference information; and

adjusting said weighing factors in response to said updated viewer preference information.

10. A method for selecting audiovisual programs for presentation to a viewer, each of the audiovisual programs having a plurality of program attributes and a corresponding content code comprising respective fields of information pertaining to the plurality of program attributes of the audiovisual program, comprising the steps of:

storing a viewer preference file, wherein said viewer preference file comprises a plurality of attribute ratings corresponding to the plurality of program attributes, wherein each of said attribute ratings represents the viewer's preference of the program attribute corresponding to said rating;

for a plurality of the audiovisual programs, receiving a plurality of the corresponding content codes;

multiplying fields of a predetermined content code with corresponding fields of said viewer preference file to obtain a plurality of products for a predetermined audiovisual program;

applying said plurality of products to a neural network;

determining a grade corresponding to said predetermined content code based on said products;

repeating said receiving, multiplying, applying, and determining steps for a plurality of content codes to obtain a plurality of corresponding grades for a plurality of corresponding programs;

choosing a subset of said plurality of corresponding grades based on the relative magnitudes of said grades; and

storing a preferred list of audiovisual programs corresponding to said grades in response to said choosing step.

11. The method of claim 10 and further comprising the steps of:

displaying a predetermined audiovisual program to a viewer;

receiving ratings from the viewer corresponding to the attributes for said predetermined audiovisual program; and

updating said viewer preference file.

12. The method of claim 10 and further comprising the steps of:

displaying said preferred list of audiovisual programs to a viewer;

soliciting a ranking from the viewer for each of said preferred list of audiovisual programs; and

updating said viewer preference file in response to said soliciting step.

13. Apparatus for selecting audiovisual programs having a plurality of program attributes, comprising:

means for storing a viewer preference file, wherein said viewer preference file comprises a plurality of attribute ratings corresponding to the plurality of programming attributes, wherein each of said attribute ratings represents the viewer's preference of the program attribute corresponding to said rating;

means for receiving a plurality of the audiovisual programs having a plurality of corresponding content codes, wherein each of said content codes comprises a plurality of information fields representing the plurality of program attributes; and

means for comparing said viewer preference file to said plurality of the corresponding content codes, such that each of said viewer's attribute ratings is compared with the corresponding information field in said corresponding content code.

14. The apparatus of claim 13 and further comprising means for selecting at least one of the plurality of audiovisual programs in response to said comparing means.

15. The apparatus of claim 13 and further comprising means for updating said viewer preference file.

16. The apparatus of claim 13 wherein said means for comparing comprises neural network means.

17. The apparatus of claim 13 and further comprising:

means for displaying a predetermined audiovisual program to a viewer; and

means for receiving ratings from the viewer corresponding to the attributes for said predetermined audiovisual program.

18. The apparatus of claim 13 and further comprising means for selecting a subset of the plurality of audiovisual programs in a preferred viewing list in response to said comparing means.

19. The apparatus of claim 18 and further comprising:

means for displaying said preferred list of audiovisual programs to a viewer; and

means for soliciting and receiving a ranking from the viewer for each of said preferred list of audiovisual programs.

20. The apparatus of claim 13 and further comprising means for transmitting said corresponding content codes.
