Abstract
A contents database 114 memorizes the discriminating information for discriminating contents and the temporal information as to the time of content duplication associated with the discriminating information. A recording program 113 acquires the discriminating information of contents to be duplicated and duplicates the contents in association with the acquired discriminating information and with the temporal information memorized in the contents database 114. This substantially prohibits duplication in large quantities without significantly impairing the interests of a user.
Claims13
An information processing method comprising:
- storing information for discriminating contents duplicated in the past with respect to a specific device and temporal data as to a previous start time of duplication of the contents into a database of the specific device;
- requesting a further duplication of the contents with respect to the specific device;
- acquiring the information for discriminating content to be duplicated from the database of the specific device;
- deciding whether copying of the contents discriminated by the discriminating information is allowed in accordance with a comparison between the temporal data stored in the database and current time;
- allowing copying of the content;
- and duplicating the contents in accordance with said decision wherein the duplication of the content is prohibited when an interval of time between the current time and the previous start time of duplication of said content specified by the temporal data stored in the database with respect to the predetermined device is less than predetermined amount of time.
A program storage medium including computer program instructions that cause a computer to implement an information processing method comprising:
- storing information for discriminating contents duplicated in the past with respect to a specific device and temporal data as to a previous start time of duplication of the contents into a database of the specific device;
- requesting a further duplication of the contents with respect to the specific device;
- acquiring the information for discriminating content to be duplicated from the database of the specific device;
- deciding whether copying of the contents discriminated by the discriminating information is allowed in accordance with a comparison between the temporal data stored in the database and current time;
- allowing copying of the content;
- and duplicating the contents in accordance with said decision, wherein the duplication of the content is prohibited when an interval of time between the current time and the previous start time of duplication of said content specified by the temporal data stored in the database with respect to the predetermined device is less than predetermined amount of time.
