7. The index imparting system according to claim 6, wherein the database stores the detailed information on at least any one of a person, news, or a script.

8. The index imparting system according to claim 6, wherein the attribute information registering section is connected online to a device to edit a VCR or a telop, and attribute information which is registered to the attribute information registering section is obtained by registering online information obtained or input by using the editing device.

9. The index imparting system according to claim 6, wherein attribute information which is registered to the attribute information registering section is obtained by storing information obtained or input by using a device to edit a VCR or a telop in a removable medium as the attribute information, and registering the information by using the removable medium.

10. The index imparting system according to claim 1, wherein the control signal detecting section identifies a time on which detection of the control signals starts as a start time, identifies a time on which detection of the control signals are finished as an end time, and then adds a time zone information between the start time and the end time to the metadata as an attribute information of the control signals.
