Abstract: In a content playback system 2, when receiving, from an information playback apparatus, a first request that queries a right status and a playback status of a digital content, a right management apparatus 7 references a right management DB to obtain the right status, and obtains the playback status from an information playback apparatus having the playback right of the digital content. The right management apparatus 7 transmits, to the information playback apparatus 5, a first response indicative of the right status and playback status of the digital content. When determining, based on the received first response, the information playback apparatus 5 that the digital content is not being played back, transfers, based on the right status of the received first response, the playback right of the digital content from the information playback apparatus having the playback right of the digital content to the corresponding apparatus.

Abstract: A disk-layer-configuration judging unit (180) of a recording-and-reproducing apparatus (100) judges which of a one-layer disk (10) and a two-layer disk (20) is a disk in which content data is to be recorded. A system controller (280) sets a recording rate to be a conventional recording rate when the disk-layer-configuration judging unit (180) judges that the disk is the one-layer disk (10) while setting the recording rate to be a recording rate that makes the maximum recordable time twice as much as the maximum recordable time of the one-layer disk (10) when the disk-layer-configuration judging unit (180) judges that the disk is the two-layer disk (20).

Abstract: The encoding rate controlling apparatus (9) is provided with a controlling device (9a, 9b) for performing a control for the encoding rate by changing a quantization scale code for quantizing the dynamic image information, and for conversing an average value of the encoding rate through all of the dynamic image information to an average value corresponding to a predetermined average value. The controlling device establishes on a time axis a plurality of change timings, each of which is a timing when the quantization scale code is changed, calculates the average value of the encoding rate corresponding to each of the established change timings, and performs the control for the encoding rate on the basis of the calculated average value.

Abstract: Management information in a recording medium or a HD mounted on an information processing apparatus (400) is recorded in an external medium mounted on the information processing apparatus (400). The external medium is mounted on a portable information editing apparatus (300), and the management information is displayed by a terminal display apparatus. Based on this reproduction, modification management information is generated by editing a content for managing content information in the information processing apparatus (400), and then recorded in the external medium. The external medium is mounted on the information processing apparatus (400) again so that the modification management information is received by a modification management information receiving section to be recorded in the recording medium or the HD, while the content information is edited automatically based on the edited content of the modification management information.

Abstract: Content information in a recording medium or HD mounted on an information processing apparatus (400) is recorded in an external medium mounted on the apparatus (400). The external medium is mounted on a portable information editing apparatus (300), and the content information is reproduced by a terminal display apparatus and/or a terminal speaker apparatus. Based on the reproduction, data area of the content information to be reproduced by the apparatus (400) is set and edited using a terminal input section, and edited script information is generated and recorded in the external medium. The external medium is mounted on the apparatus (400) again, and the edited script information is received by the instruction information receiving section and recorded in the recording medium or the HD. The content information can be reproduced as a content edited by the portable information editing apparatus (300), thus the editing is executed easily and effectively.
