摘要： In a contents data recording medium according to the present invention, a plurality of pieces of contents data are recorded as individual files. The contents data recording medium includes: link information which indicates at least positions and sizes of the contents data on the contents data recording medium; metadata which describes contents of the contents data and is used for retrieval of the individual files; and a management file which includes the link information and the metadata. By use of the management file, an access device which accesses the contents data recording medium retrieves the contents data.

摘要： A printer has a display for selectively displaying a plurality of menu screens for setting various printing conditions. The menu screens include a standard menu screen and a specific-purpose menu screen. The standard menu screen includes a plurality of menus selectable for setting the printing conditions. The specific-purpose menu screen is, for example, a CD-R menu screen including some of the menus of the standard menu screen, or the menus related to printing conditions of a CD-R. The printer includes an insert opening into which the CD-R, or a printing medium, is inserted and a CD-R guide selectively opening or closing the insert opening. When the CD-R guide is open, the CD-R menu screen is automatically displayed on the display.

摘要： The present invention provides a recording/reproduction device which allows reproduction with a small delay. At the time of storing a program in a storage medium, the recording/reproduction device creates a contents key for encrypting the program data, encrypts the program data with the contents key, and stores the encrypted program data in the storage medium. Upon the user giving instructions for reproduction of the program which is being recorded, i.e., time-shift reproduction, the recording/reproduction device uses the same contents key already held for recording of the program. That is to say, the recording/reproduction device makes a copy of the license data including the contents key, reads out the encrypted program data from the storage medium, and decrypts the encrypted program data with the copy of the contents key, whereby the encrypted program data is reproduced. In this case, the step for reading out the contents key from the storage medium is omitted.

摘要： The present invention provides a recording/reproduction device which allows reproduction with a small delay. The recording/reproduction device encrypts digital contents, and records the encrypted digital contents on a removable HDD unit. At the time of reproduction, the recording/reproduction device decrypts the encrypted digital contents recorded on the removable HDD unit. A contents key for decrypting the digital contents is input/output by executing a series of cryptography input/output processing actions. In the event that the removable HDD unit enters the state wherein the removable HDD unit can be used, the recording/reproduction device executes reproduction session establishment processing including device authentication processing beforehand. In the event that there are any sessions which can be established in parallel for executing cryptography input/output processing, recording session establishment processing is executed. Upon reception of user instructions for reproduction, the recording/reproduction device skips device authentication processing, and executes the subsequent cryptography input/output processing for acquiring the contents key.

摘要： There are described a data recording system, a data recording method, and a recording medium, all of which are directed to enabling easy editing of AV data without involvement of duplication of the AV data, as well as to eliminating a necessity for an additional data recording region. In the recording system, at the time of recording of primary data, there is prepared an original file which stores link data formed by arranging in sequence address data for reproduction purposes stored in a recording region on a recording medium. Further, through editing of the original file, there is prepared a virtual file which stores link data formed by arranging in sequence address data for reproduction purposes stored in the recording region on the recording medium. The data are reproduced according to these files.

摘要： A content receiver receives content data distributed repeatedly from a distribution station. The content data are stored in a content storage. A reproduction processing unit sequentially reproduces parts of the content data stored in the storage corresponding to content data received by the content receiver. A content management unit monitors the degree of completion of the content data stored. When the monitored degree of completion becomes a preset level or above, a connection processing unit disconnects connection to the distribution station. After the connection has been disconnected, an identifier receiver receives reproduction information informed from the distribution station. The reproduction processing unit reproduces the content data according to the reproduction information.

摘要： A storage device formed of a hard disk stores a search table including an index object, a start time stamp, an end time stamp, a decryption start point correlated with index object, and a GOP location offset correlated with index object. Decryption start point indicates a decryption start point for a block including audio and video data broadcast in synchronization with an object and GOP location offset indicates an amount offset between a decryption start point and GOP's random access point.
