Abstract

Automatic video recording system and method are provided which make it possible that programs to be automatically recorded are selected according to objective criteria from the programs that are scheduled to broadcast in the future. In configuration, an information generator of a program information providing server ranks the broadcast programs on the basis of program rating information, and thus generates program rank prediction information. Terminal units download the program rank prediction information and an electronic program schedule. A recorded-program/digest generator makes broadcast programs of a certain rank or above be automatically recorded by referring to the program rank prediction information.

6. A video recording system according to claim 5, wherein

said program rank information includes a first rank defining that said broadcast programs are a series of programs and that the previous viewing rating is larger than a predetermined value, a second rank defining that said broadcast programs are a series of programs and that their viewing ratings are larger than those of the other programs of the same time zone, and a third rank defining that the actors of said broadcast programs appear in the past programs of the same genre, and that their viewing ratings are larger than a predetermined value, and

said recording control means makes timer setting for recording said broadcast programs of said first rank or said second rank based on said program rank information or makes timer setting for recording said broadcast programs of said third rank based on said program rank information and of which the program information includes said user parameter.

7. A video recording system according to claim 1, wherein

said program rank information includes information about such ranks of certain time units of each of said broadcast programs as given according to their viewing ratings, and

said recording control means makes editing to cut video information of time zones of a certain rank or above based on said program rank information away from recorded video information and to generate digest video information of said recorded video information.

8. A video recording system according to claim 1, wherein

said program rank information has information about such ranks of certain time units of each of said broadcast programs as given according to their viewing ratings, and

said recording control means cuts video information of time zones of a predetermined rank or above based on said program rank information away from recorded video information, and makes said cut-away video information be reproduced.

9. A video recording system for recording and reproducing video information comprising:

program rank information acquiring means for acquiring program rank information produced according to the viewing ratings of broadcast programs;

means for storing a user parameter that specifies the video information that the user likes; and

recording/reproducing control means for controlling the recording and reproduction of video programs on the basis of said program rank information acquired from said program rank information acquiring means and said stored user parameter.

10. A video recording system according to claim 9, wherein

said program rank information is formed of information about such rank of each of said broadcast programs as given according to its viewing rating, and

said recording control means makes timer setting for recording said broadcast programs of a predetermined rank or above based on said program rank information.

11. A video recording system according to claim 9, further comprising:

means for storing said program rank information about such rank of each of said broadcast programs as given according to its viewing rating, and a user parameter for specifying video information that the user likes, wherein

said recording control means makes timer setting for recording said broadcast programs of a predetermined rank or above based on said program rank information or of said broadcast programs of which the program information includes said user parameter.

12. A video recording system according to claim 9, wherein

said program rank information has information about such ranks of certain time units of each of said broadcast programs as given according to their viewing ratings, and

said recording control means makes editing to cut video information of time zones of a certain rank or above based on said program rank information away from recorded video information, and generates digest video information of said recorded video information.

13. A video recording system according to claim 9, wherein

said program rank information has information about such ranks of certain time units of each of said broadcast programs as given according to their viewing ratings, and

said recording control means cuts video information of time zones of a predetermined rank or above based on said program rank information away from recorded video information, and makes said cut-away video information be reproduced.

14. A timer-recording information providing server for providing information useful for recording video information comprising:

means for storing schedule information of broadcast programs;

program rank information generating means for generating program rank information based on the viewing ratings of already broadcast programs;

timer-recording information generating means to generate timer-setting information for video programs on the basis of said program rank information and said broadcast schedule information; and

timer-setting information delivering means for delivering said timer-setting information to video recording units connected to said server.

15. A server according to claim 14, wherein

said program rank information generating means ranks each of said broadcast programs according to predetermined viewing ratings or the time zones of each of said broadcast programs according to predetermined viewing ratings to thereby produce said program rank information.

16. A server according to claim 15, wherein

said timer-setting information generating means generates timer-setting information for said programs of a certain rank or above based on said program rank information according to said broadcast schedule information.

17. A server according to claim 14, further comprising:
