    摘要: A recording apparatus reads a content management file from a file information obtaining means, and a data analysis and search means searches for a specified digital content information storing portions from the read content management file and searches for a play list file including specified digital contents in reproduction order based on reference play list information of the content information storing portions. The file information obtaining means reads a relevant play list file, and the data analysis and search means searches for an updated location and notifies a play list file creation means thereof so that the play list file creation means correctly updates the play list file.

    摘要: [Object] When additional recording is performed by a recording apparatus and a program of a different method of management information construction to a recording medium having recorded thereon management information data such as a content parameter, a menu, a play list and a menu display image together with content data such as an audio, a static image and a video, consistency of the management information data is lost. [Solution] It is possible to record in a file header portion 31 of a management information file group 2 an editor identifier 33 for identifying an apparatus and a program having edited that file, trace update history of the file with a file management device 14 and update information with a management information file creation device 15 by reflecting an intention of management information already recorded so as to keep the consistency of the management information.

    摘要: A source generates a medium key (KM) and a media secret table including a plurality of entries, each entry including (KM) encrypted by a public key (PU-PD) of a plurality of devices, obtains the medium ID of a medium therefrom, generates a content key (KD) for a piece of content, encrypts the content with (KD) to result in (KD(content)), encrypts (KD) with (KM) to result in (KM(KD)), generates a package for the content including (KD(content)), (KM(KD)), the medium ID, and a signature based on at least the medium ID and verifiable with (KM), and copies the generated package and the media secret table to the medium. Thus, a device with the medium and a private key (PR-PD) corresponding to an entry of the media secret table can access and render the content.
