摘要:
The present invention relates to a recording apparatus and a record medium for recording a data read time, a seek time, a successive reproduction time, a successive record length, and a correlation among data pieces. A recording apparatus of the present invention is a recoding apparatus for recording data to a rewritable record medium, comprising an encoding means for encoding the data corresponding to a predetermined compressing and encoding system, a converting means for converting a data structure of encoded data that is output from the encoding means into a file structure that a computer software program that synchronously reproduces a moving picture and so forth can handle without need to use a special hardware device, and a recording means for recording data having the file structure to the record medium, wherein the file structure has a first data unit, a second data unit, and a data portion, the second data unit being a set of a plurality of first data units, the data portion describing management information, wherein the plurality of second data units is correlated with a successive record length of the record medium, and wherein the data portion contains a time length and a data length of the second data unit recorded in the successive record length.

A recording apparatus such as an optical disk and a file management method are disclosed by which, where an index file is formed from groups of data wherein extract information is collected for different types and one of the groups of data is used to collectively manage the other groups of data, a process relating to deletion or addition of extract information can be executed simply, easily, and with certainty. In each of slots of a property entry, information representing whether the slot is valid or invalid and information representative of a relationship to different slots to which extract information relating to the same file is allocated are recorded, and a combination of the slots in which the extract information of the one file is allocated is managed with the property entry.
摘要:
A data processing apparatus and an external storage apparatus arranged to transmit data by using serial signals and capable of reducing the number of signal lines for use to transmit serial data. A CLK line, a control line and a DT line are arranged between a data processing apparatus and a memory card. The DT line is a line through which data and commands formed into serial signals are bidirectionally transmitted. A synchronizing signal is transmitted to the CLK line. A control signal is supplied from the data processing apparatus to the memory card through the control line. In a period of time in which the signal level of the control signal is a high level, data or a command is transmitted to the DT line. In a period of time in which the signal level of the control signal is a low level, a status signal is transmitted to the DT line from the memory card.

摘要:
An information processing system includes: an imaging device including a first recording medium recording a content file, and a management information storage unit storing management information for managing the content file in the first recording medium; an information processing device including a second recording medium recording a predetermined content file; and a control unit controlling so as to detect difference information relating to the storage state of the content file recorded in the first recording medium, based on the results of comparing present management information stored in the management information storage unit, with past management information which has been recorded before the present management information and is management information of the point-in-time at which the content file in the first recording medium was saved to the second recording medium, and record, in the second recording medium, the content file in the first recording medium, based on the detected difference information.
摘要:
A recording apparatus, a reproduction apparatus and a file management method are disclosed wherein, even if one of files recorded on a recording medium cannot be reproduced regularly, another file selected by the user can be reproduced normally. A file having a hierarchical structure formed from video data and audio data both in the form of compressed data together with information necessary for processing of the video data and audio data is produced and recorded on a predetermined recording medium. Upon production of the file, information regarding decoding of the video data and audio data is disposed collectively on the top side of the file.

The present invention provides an editing apparatus, a reproducing apparatus, and a recording medium for reproducing special effects by full use of the capabilities of the reproducing apparatus. The editing apparatus having original video data and edited data that are a collection of editing codes for performing an editing operation with a desired editing type on a desired portion in the original video data to generate edited video data includes a primary conversion table attaching means for attaching, to the editing video data, a primary conversion table for correlating at least the desired editing type with a standard editing type specified as standard in advance.
摘要:
The occurrence of fragments is suppressed in an index file that manages individual contents files recorded on a recording medium. On an optical disk 2, a contents file and an index file that manages each of the contents files are recorded. The index file is formed of attribute information of each of the contents files (including text data of a title, thumbnail image data and so on). When a predetermined contents file is recorded on the optical disk 2, a microcomputer 19 updates an index file so as to register this predetermined contents file in the index file. In this case, the microcomputer 19 secures a predetermined number of continuous slots in fixed length in the index file, and allocates attribute information of this predetermined contents file to the slots. For example, a predetermined number is set to the maximum number of the slots, or to the average number of the slots to be predicted for use in order to register the contents file.
摘要:
Content files and an index file for managing the content files are recorded in a recording medium. The index file includes, for example, a text file FTX, a thumbnail picture file FTH, and a property file FP. The files each have continuous fixed-length slots. The fixed-length slots are each managed by a slot number (index information) indicative of the order of arrangement thereof. Each file has a predetermined number of management information areas including one or a plurality of continuous fixed-length slots. The management information areas are identified by the index information of the first fixed-length slot. A predetermined entry has a slot number for identifying another entry. The data on the other entry can be acquired by detecting the location of the other entry on the index file.
