Abstract

The present invention enhances user friendliness of a system which is controlled by use of on-screen display by disabling the operation of these devices if it not permitted. According to the invention, when a recording of a received program is attempted, the program is checked for copy protection. If the program is found copy protected, a warning thereof is displayed and control of a recording/reproducing device concerned is disabled. This warning display allows the user to determine whether or not a program being received is copy protected beforehand, thereby preventing the video signal containing a copy protection control signal from being recorded on the recording/reproducing device. In addition, according to the invention, when a record button is pressed, it becomes a record stop button, being put in the selected state. This further enhances the user friendliness.

Claims

1. A receiving system composed of a receiving device, a monitor device for displaying an output of said receiving device, and an external recording device to be controlled by said receiving device, said receiving device comprising:

on-screen display control means for displaying a screen corresponding to various setting states and setting items on said monitor device in an on-screen manner;

external device control means for setting an operation of said external recording device; and

control means for, when a recording input is given, determining whether or not a program being received is copy protected, setting said external recording device to a recording state if said program is found not copy protected, and disabling control of said external recording device if said program is found copy protected.

2. The receiving system according to

claim 1

, wherein, if said program is found copy protected when said recording input is given, a warning indicative of copy protection is displayed in an on-screen manner.

3. The receiving system according to

claim 1

, wherein, when said recording input is given, an on-screen display is provided through which stop of recording is operated.

4. The receiving system according to

claim 3

, wherein, when said recording input is given, a button for stopping recording is put in a selected state on said on-screen display.

5. The receiving system according to

claim 1

, wherein said external device control means controls said external recording device by use of an AV mouse.

6. The receiving system according to

claim 1

, wherein said external device control means controls said external recording device by use of an IEEE 1394 interface.

7. A receiving apparatus comprising:

on-screen display control means for displaying a screen corresponding to various setting states and setting items in an on-screen manner;

external device control means for setting an operation of an external recording device; and

control means for, when a recording input is given, determining whether or not a program being received is copy protected, setting said external recording device to a recording state if said program is found not copy protected, and disabling control of said external recording device if said program is found copy protected.

8. The receiving apparatus according to

claim 7

, wherein, if said program is found copy protected when said recording input is given, a warning indicative of copy protection is displayed in an on-screen manner.

9. The receiving apparatus according to

claim 7

, wherein, when said recording input is given, an on-screen display is provided through which stop of recording is operated.

10. The receiving apparatus according to

claim 9

, wherein, when said recording input is given, a button for stopping recording is put in a selected state on said on-screen display.

11. The receiving apparatus according to

claim 7

, wherein said external device control means controls said external recording device by use of an AV mouse.

12. The receiving apparatus according to

claim 7

, wherein said external device control means controls said external recording device by use of an IEEE 1394 interface.

13. A control method for controlling a receiving system composed of a receiving device, a monitor device for displaying an output of said receiving device, and an external recording device to be controlled by said receiving device, wherein said receiving device determines, when a recording input is given, whether or not a program being received is copy protected, sets said external recording device to a recording state if said program is found not copy protected, and disables control of said external recording device if said program is found copy protected.

14. The control method for controlling a receiving system according to

claim 13

, wherein, if said program is found copy protected when said recording input is given, a warning indicative of copy protection is displayed in an on-screen manner.

15. The control method for controlling a receiving system according to

claim 13

, wherein, when said recording input is given, an on-screen display is provided through which stop of recording is operated.

16. The control method for controlling a receiving system according to

claim 15

, wherein, when said recording input is given, a button for stopping recording is put in a selected state on said on-screen display.

17. The control method for controlling a receiving system according to

claim 13

, wherein said external recording device is controlled by use of an AV mouse.

18. The control method for controlling a receiving system according to

claim 13

, wherein said external recording device is controlled by use of an IEEE 1394 interface.
