5. An information processing apparatus according to

claim 4

, wherein said input means includes:

reception means for receiving transport stream data transmitted by the digital television broadcasting; and

deriving means for deriving the image data from the EPG data received by said reception means.

6. An information processing apparatus according to

claim 5

, further comprising a memory unit for storing the EPG data derived by said deriving means, wherein said control means responsive to a change in a program including images displayed by said display means derives the program information data of the changed program from the EPG data stored in said memory unit.

7. An information processing apparatus according to

claim 6

, further comprising manual setting means for setting contents of program information to be displayed by said display means, wherein said control means derives the program information data from the EPG data in accordance with the contents of the program information set by said manual setting means.

8. An information processing apparatus according to

claim 1

, wherein said control means controls said display means to display at least one of a channel number, a program name, program contents, and program detailed contents, as the program information of the changed program.

9. An information processing apparatus according to

claim 1

, further comprising manual setting means for setting contents of program information to be displayed by said display means.

10. An information processing apparatus according to

claim 9

, wherein said manual setting means sets at least one of a display timing of the program information, a display area, a display character size, a display method, a display speed, the number of display repetitions, and display contents.

11. An information processing apparatus according to

claim 1

, further comprising change instructing means for instructing to change a program including images displayed by said display means from a first program to a second program, wherein said control means controls said display means to display the program information of the second program and images of the second program on the same screen.

12. An information processing apparatus according to

claim 11

, wherein in response to a program change instruction of said change instructing means, said control means controls said display means to inhibit a display of the program information of the first program and display the program information of the second program.

13. An information processing apparatus according to

claim 1

, wherein in response to a start of a program broadcast next to the program including images displayed by said display means, said control means controls said display means to display the program information of the next program and images of the next program on the same screen.

14. An information processing apparatus according to

claim 13

, wherein in response to the start of the next program, said control means controls said display means to inhibit a display of the program information of the program and display the program information of the next program.

15. An information processing apparatus according to

claim 1

, wherein in response to a turn-on of a power supply of the apparatus, said control means controls said display means to display the program information of the program including images displayed by said display means and the images on the same screen.

16. An information processing apparatus according to

claim 1

, wherein in response to a broadcast end of the program including images displayed by said display means, said control means controls said display means to display program information of a next program to be broadcast.

17. An information processing apparatus according to

claim 16

, wherein in response to the broadcast end of the program, said control means controls said display means to inhibit a display of the program information of the program and display the program information of the next program.

18. An information processing apparatus according to

claim 1

, wherein in response to a lapse of a predetermined time from when a display of the program information is displayed, said control means controls said display means to finish a display of the program information.

19. An information processing apparatus according to

claim 1

, wherein the image data input by said input means includes image data of the images of the program and image data of commercial images inserted in the program, and in response to a change of the program including images displayed by said display means, said control means controls said display means to display the program information on the program information data of the changed program and the commercial images on the same screen.

20. An information processing apparatus comprising:

input means for inputting image data and program information data, the program information data indicating information on a program including the image data;

output means for outputting the image data to display means to display an image relating to the image data input from said input means; and

control means responsive to a change in a program corresponding to the image data output from said output means for controlling said output means to output the program information data to said display means to display program information relating to the program information data of the changed program and the images on a same screen.

21. An information processing method comprising:

an input step of inputting image data and program information data, the program information data indicating information relating to a program including the image data;

a display step of displaying an image corresponding to the input image data on display means; and
