摘要： A reproducing device includes decoding processors and output controllers, and performs synchronous reproduction for reproducing a content item decoded by one of the decoding processors by at least two of the output controllers and separate reproduction for reproducing the content item decoded by one of the decoding processors by one of the output controllers. The reproducing device includes: a manager that manages an allowed number of reproductions of the content item; a determiner that determines, when a reproduction instruction is given, based on the allowed number of reproductions of the content item, whether the separate reproduction is possible and whether the synchronous reproduction is possible; and a controller that performs the separate or synchronous reproduction, based on the determination. The manager decrements by one the allowed number of reproductions of the content item when the separate reproduction is performed, and does not decrement it when the synchronous reproduction is performed.

摘要： A system for protection against unauthorized modifications of digital content, in particular image content, in which a content processing system retrieves content, a fingerprint for the content and at least one modification limit expressing authorized modifications to the content. The content may then be modified, but before saving or exportation is allowed, a second fingerprint is calculated, and the difference between the fingerprints is compared with the at least one modification limit. If the difference is within the allowed bounds, then saving or exportation is allowed; if not, it is prevented. Also provided are a method and a content consumer device performing essentially the same steps before allowing rendering of the content.

摘要： Copying, dubbing or reproducing copyrighted digital data can be inhibited or restricted to properly protect a copyright. AV data recorded on a pre-recorded tape is output from a reproducing unit of a first digital VCR with protective information indicating whether the copy of the AV data is inhibited or not. The protective information is input with the A/V data to a second digital VCR. Copy permission information of a blank tape loaded in the second digital VCR is discriminated and the second digital VCR records the AV data supplied from the first digital VCR based on the protective information and the copy permission information.

摘要： A copy prevention method and apparatus of a digital magnetic recording/reproducing system performs the copy prevention function by encoding to insert a marker involving copy prevention function information and executing the function and allows a program supplier to realize a desired copy prevention function of various patterns, in which the marker formed by a control word for scrambling audio and video bit straps and copy prevention information for preventing an illegal copy is encrypted by an encoded key to be multiplexed with the audio and video bit strips scrambled by the control word. The marker transmitted is detected from the bit strips to be decrypted and analyzed by the encoded key to determine whether the copy is permitted or not, so that the detected marker is updated to be recorded on a video tape and the control word is produced from the marker to perform the descrambling to supply the result to a monitor to be displayed. Thus, the program supplier selects the copy prevention function, and a separate format converting apparatus is not required since a field defined within a GA format is utilized while an existing DVCR is not need to be changed for performing the copy prevention function as the data amount to be recorded is not increased. A method and apparatus for transmitting digital data are discussed. According to an embodiment, the invention is directed to a method of transmitting digital data using a data processing apparatus including a scrambler, the method comprising: scrambling, by the scrambler, one or more data units included in the digital data based on control data, the digital data including a first data block and one or more succeeding data blocks, each data block including a header and one data unit, at least the header in the first data block including the control data, wherein the first data block and the one or more succeeding data blocks are scrambled based on the control data included in the first data block; and transmitting, by the data processing apparatus, the one or more scrambled data units and the control data, the control data being used for controlling a parameter of a scrambling/descrambling operation.
