Abstract: The present invention provides a content-on-demand system capable of managing users' system-utilization frequencies such as download counts and connection times as well as changing the quality of a content transmitted from a server to a user in dependence on the system-utilization frequency of the user. Thus, a high-quality content or a highly functional content is provided to a user with a high system-utilization frequency. By differentiating contents provided to users in accordance with the system-utilization frequencies of the users, network businesses can be activated.

Abstract: A method for processing content data includes the steps of, when content data is transmitted from a data provider, adding usage rule information prescribing a rule of usage of the content data to the content data and transmitting the content data with the usage rule information; receiving the transmitted content data; extracting the usage rule information from the received content data; and notifying a user of the content data of the extracted usage information.

Abstract: When the user designates the reproduction of searching audio data, the designated searching audio data and audio volume data are read from a searching data recording portion. The searching audio data is reproduced corresponding to the audio volume data. When the user designates the reproduction of main audio data, the audio data is read from a disc and reproduced. In addition, the number-of-reproduction-times data corresponding to the number of times the audio data has been reproduced, audio volume data, audio quality data, and time period data for the designated main audio data are updated in the searching data storing portion. The searching audio data corresponding to the designated main audio data is read from the disc in accordance with the audio quality data and the time period data and recorded to the searching data storing portion.

Abstract: A recording medium includes at least a recording area in which pieces of content data are recorded, and a lead-in area in a position that is read before the recording area is read. In one of the recording area and the lead-in area, identification information which indicates whether the recording medium is for a rental use is recorded.

Abstract: Contents data processing apparatus comprising a reproducing block for reproducing contents data from a recording medium, a character information generation block for generating character information based on first information accompanied with said contents data, and a character memory for storing second information regarding growth or change.

Abstract: A terminal apparatus comprising an insertion hole into which to insert a copyright-compliant first memory card and a copyright-noncompliant second memory card. The first and the second memory cards are substantially the same in shape. If the copyright-noncompliant second memory card is inserted preparatory to recording copyright-protected contents, the copyright-protected contents are recorded temporarily to the second memory card. When the copyright-compliant first memory card is later inserted, the recorded copyright-protected contents are transferred from the second memory card to the inserted first memory card. If the copyright-compliant first memory card is inserted preparatory to recording copyright-unprotected contents, the copyright-unprotected contents are recorded temporarily to the first memory card so that when the copyright-noncompliant second memory card is later inserted, the recorded copyright-unprotected contents are transferred from the first memory card to the inserted second memory card.

Abstract: A charging system is provided which solicits from third parties information about products supposedly infringing on a right holder's lawful right and which, upon exposure of the infringement, acquires royalty revenues from the trespassing party for a reimbursement to any third party having contributed the information on the infringement, whereby right-related information is collected more efficiently and a market on which such information circulates is actively promoted.

Abstract: A terminal apparatus into which one of a first and a second memory card is selectively inserted. The first memory card is designed to store contents subject to copyright protection whereas the second memory card is arranged to accommodate contents not subject to copyright protection. The two cards are substantially the same in shape. If a user inadvertently inserts the second memory card into the apparatus in order to record contents subject to copyright protection, the contents are allowed to be recorded to the inserted card at a lowered level of data quality. This averts an outright failure to record copyright-protected contents for which the user has properly paid to a copyright-noncompliant memory card.

Abstract: One network system according to the invention allows a party potentially disadvantaged by a third party's right globally to solicit information for contesting the right in question and to pay a reward to individuals or organizations for offering the information for invalidation. The system ensures that legitimate rights are protected while corporations are defended against unfair accusations and frivolous lawsuits. Another network system according to the invention allows a party potentially disadvantaged by a third party's right globally to recruit experts willing to take over proceedings on behalf of the disadvantaged party for invalidating the right in question, and to pay a contingent fee to those who successfully invalidated the right. The inventive system also ensures that legitimate rights are protected while corporations are defended against unfair accusations and frivolous lawsuits.
