Description

Recording playback system, recording playback method, program and recording medium {RECORDING / REPRODUCTION SYSTEM, RECORDING / REPRODUCTION METHOD, PROGRAM, AND RECORDING MEDIUM}

The present invention relates to, for example, a recording / playback system, a recording device, a playback device, a recording medium, a recording / reproducing method, a recording method, a reproducing method, and a program used for recording digital data as a file.

CDs or DVDs recorded with music or video content viewed using a portable playback device were originally commercially available or rented products.

With the recent spread of PCs, PC users have maintained music data riped off from music CDs, music data or video data downloaded via the Internet on file HDDs of PCs. In addition, PC users have recorded these music data and video data in CD-R or CD-RW in a file format.

Portable playback devices capable of playing these files or portable playback devices capable of utilizing other media are also known.

In the case of recording in a file format, data is often compressed, and the compression or the quality of voice or video may be degraded, but the advantage is that a large amount of content can be stored in a single medium.

When storing music data in a file format, information such as composer (text or picture), performer (text or picture, etc.), lyrics, and other comments can also be stored in the same file using the ID3 tag of the MP3 method. Can be stored.

In the case of video data, information such as camera setting conditions, camera names used, and other comments can be held in the same file by using EXIF in the JPEG system.

In the AVI system, information such as a playback time, a screen size and frame rate of a video, a sampling frequency and a number of channels of audio is held in a portion called a header.

This information is useful not only when playing a file, but also for checking or searching for a file.

In addition, although the functions described above were initially mounted in portable playback devices, they have been implemented not only in portable but also in stationary playback devices.

In the CD-ROM, these files are managed in accordance with the file system specified in ISO9660, and directories are constructed as specified by the PC, and each file is recorded in a form belonging to somewhere in the directory.

When the CD-ROM thus produced is to be reproduced by a conventional portable reproducing apparatus, first, what is recorded on the CD-ROM is examined.

Therefore, based on the file system, the directory structure and the files belonging to each directory are displayed from the root directory.

When the file to be played back is selected by the user, the recording position of the selected file is checked, and playback of the file is started.

However, the above-mentioned conventional reproducing apparatus has the following disadvantages.

1) In particular, when the recording medium is not a memory such as a compact flash but a disk medium such as a CD or a DVD, the data read / write speed of a conventional reproducing apparatus is much higher than that of a PC HDD. slow.

2) The ability of a playback device to display the contents of media such as directory names and file names is inferior to that of PCs.

3) Portable playback devices usually have a small display and cannot display color. Many devices have a display only on either the remote control or the main unit, and sometimes require operation without a display.

4) The input means of the playback apparatus is poor compared to the input means of the PC.

In addition, since media recorded on the basis of the file system described on the premise of being used in a PC are reproduced by a conventional reproducing apparatus, the following disadvantages exist.

1) It takes time for the recorded content to be displayed after inserting the media into the playback device.

2) In order to display information (property, etc.) about each file used in a PC, it is necessary to read the information in each file, which takes more time.

3) It is difficult to know the displayed contents.

4) It is difficult to find the data to play back.

5) When recording, files are recorded on the media in the order selected by the PC (alphabetical order, etc.), so the playback order becomes irregular.

6) The operation of the device is bad.

The information registered in the description file 16 is the content described in Table 1, for example.

As information about a file, first, information (an extension, file name, file size, file creation and update date, etc.) registered in a file system such as FAT 32 is present.

The information unique to each of these files cannot or must not change. Although the extension cannot be changed, the file types are distinguished by the extension, so changing the extension makes it impossible to know how to process the data and the data cannot be reproduced.

The information related to the data of the file which the file embeds is as follows.

(a) Regarding moving image data, as header information in the AVI file format, wmv file format, and asf file format, an image size, frame rate, data rate, encoded information, playback time, etc., which define the video data of the file, etc. Is written.

(b) As to the audio data, as header information in the AVI file format, wma file format, and asf file format, sampling frequency, number of channels, compression method information, playing time, data rate, etc., which define the audio data of the file, etc. Is written. As the header information in the MP3 file format, text information about the composer and the player in the ID3 TAG, lyrics information, a photo of the album jacket, and the like are written.

(c) Regarding the still picture data, information of shooting conditions such as the EXIF method in the JPEG file method, information of a photographed camera, and the like are written.

Of these pieces of information, file-specific information that defines the data itself (which is a so-called mandatory attribute) is changed so that the data cannot be reproduced correctly.

In contrast, text information and the like are originally optional, and there is no problem even if these information are not maintained. If the data of the correct contents are not maintained, the information is not accurate. However, there is a case in which an incorrect result is used in the search, but there is no other adverse effect.

In reality, texts such as titles and lyrics are not the same depending on the language (for example, Japanese, English, etc.). Moreover, even when the URL information concerned is correct at the time of registration, the site indicated by the URL may move or disappear. Not only video and audio data but also ordinary event files have the same information, such as comments and thumbnails.

In addition, the detailed structure of each means of this embodiment is demonstrated later.

Next, the operation of the recording and reproducing system of the present embodiment will be described. In addition, one embodiment of the recording and reproducing method of the present invention will be described with reference to the operation of the recording and reproducing system of the present embodiment (the same applies to the following embodiments).

Operation of the recording apparatus 10; The write file management means 11 selects the data file of the data file group 13 to be recorded on the recording medium 15 by the internal storage means 12.

And the control means 21 selects the data file of the data file group 13 to output according to the instruction | indication from the reproduction instruction | indication means 22, and the data file group 13 selected by the data file output means 24. ) Converts the contents of the data file from file format to output format.

The information is existing information at the time when the data file is present in the internal storage means 12. Of course, the writing file management means 11 may create the description file 16 by newly gathering the information concerning the data file of the data file group 13 and the information regarding the link file of the link file group 17.

In the reproducing apparatus, although the reproducing instruction means 22 is described so as to reproduce on the premise of the instruction by the remote control, it is obvious that the equivalent function can be realized by the instruction by the panel or the like attached to the main body. Alternatively, if there is no instruction, the reproducing apparatus may have a function of automatically reproducing in the order specified by the description file.

In addition, the display content of the recording medium by the playback apparatus is arbitrary. Of course, the means for displaying the contents of the recording medium may be used as the data file output means 24.

In this way, by centrally recording necessary relevant information in one place, only one place on the recording medium can be accessed and read out collectively, so that the contents of the recording medium can be displayed quickly. In addition, since various related information can be displayed at the same time, the contents of each data file can be grasped easily, and the data file to be played back can be easily found. In addition, since the relevant information is concentrated in one place and it is not necessary to examine data files one by one, not only the processing of displaying the contents first and then reproducing them, but also functions such as condition search can be easily realized. Will be.

Next, more detailed structure etc. of each means of a present Example are demonstrated.

1 will be described with reference to FIG. 2 which is a block diagram of the write file management means 11 of the first embodiment of the present invention.

First, the writing file selecting means 31 selects a data file of the data file group 13 to be recorded on the recording medium 15 (one by one may be selected by the user or may be automatically selected on a certain basis). .

The file information extracting means 32 accesses the file system or interprets the contents of each file in a predetermined order to extract information related to each of the data files of the selected data file group 13.

The description file generating means 33 generates the description file 16 from the obtained information.

Moreover, the description file generation means 33 produces | generates the link file of the link file group 17 as a file different from the data file of the data file group 13 from the obtained information (link file is, for example, In the case where the data file stores music data, information such as photos of the album jacket is stored).

Moreover, the write file management means may have the structure of the write file management means 11 'shown in FIG. 3 which is a block diagram of the write file management means of another embodiment of the present invention.

34 denotes additional information input selection means, and 35 denotes a description file generation means.

The configuration and operation of the writing file selecting means 31 and the file information extracting means 32 are the same as the configuration and operation in this embodiment.

The additional information input selecting means 34 sets the related information or link files 17a and 17b to be added to the data file of the data file group 13 selected for recording on the recording medium 15. Of course, the additional information input selection means 34 may operate in accordance with the file-specific related information by the user or the manual setting of the link files 17a and 17b, or may operate according to the automatic setting using certain criteria.

The description file generation means 35 generates the description file 16 using the information obtained by both the file information extraction means 32 and the additional information input selection means 34. The description file generating means 35 has information such as photographs, lyrics, intro data, and the like, and generates link files 17a and 17b different from the data files of the data file group 13.

As the related information, the video data file can be handled more easily, and the contents of the data files of the data file group 13 can be more easily grasped.

(2) A more detailed configuration and operation of the control means 21 will be described with reference to FIG. 4, which is a block diagram of the control means 21 of the first embodiment of the present invention.

41 is a description file analyzing means, 42 is a content list of the recording medium, and 43 is an output file selecting means.

The description file analyzing means 41 analyzes the contents of the description file 16 read out from the recording medium 15, and writes necessary information into the contents list 42 of the recording medium in accordance with the function of the reproduction device 20. . The description file analyzing means 41 then displays the contents of the recording medium 15 based on the contents.

Specifically, a list of recorded data files and related information are displayed.

The output file selecting means 43 reads out information necessary for the reproduction, such as the recording position of the data file of the data file group 13, which has been instructed to output, from the contents list 42 of the recording medium, to the file reproducing means 23. send.

(3) A more detailed configuration of the description file 16 will be described with reference to FIG. 5, which is an explanatory diagram of the description file 16 of the first embodiment of the present invention.

The description file 16 is described in a format similar to HTML (Hyper Text Mark-up Language).

Here, the description file 16 has the same configuration as the configuration A1. In addition, "the description of each" play list entry "in the structure A1 has the same structure as the structure A2. In addition, the "description of each" file entry "(3 total positions) in the structure A1 has the same structure as that of the structure A3, respectively. In addition, "the description of" entry according to data type "in structure A3 has the same structure as any of structure A31-A33.

First, information about the entire recording medium 15 is described as a media entry.

Such information includes format version information of a description format, the number of play lists, and the like.

Since the format of the description file 16 is upgraded as the information to be described increases, there is a need for information for judging whether or not the format can be supported by the playback apparatus. Thus, the format version information of the description format is prepared.

In addition, a play list specifying a playback order is prepared (when there is no such play list, (a) physically recorded order, (b) random, (c) file name order, etc.). Is used in order to play the data file).

In the present embodiment, (plural) play lists are written in the description file 16.

When many songs are recorded on the recording medium 15, it is considered impractical to reproduce all the data files in the same order at all times. By preparing a plurality of play lists and selecting a play list to be reproduced at that time, it is possible to simply select a data file of the data file group 13 to be reproduced. By doing so, it is possible to reproduce in the playback order in which the intention of the playlist creator is reflected.

In the play list, file entries generated for each data file of the data file group 13 are described in accordance with the reproduction order of the data files of the data file group 13.

Playlists are classified into two types, Default and Optional.

In the default playlist, file entries of all data files of the data file group 13 on the recording medium 15 are necessarily registered only once. If only the default playlist is present, the data files of all the data file groups 13 can be played (even without the optional playlist).

An optional playlist does not have to register every file. Of course, when the data file of the same data file group 13 is to be reproduced plural times, instead of recording the plural data files of the data file group 13, the same file entry is plural times in an optional play list. Record it. By doing so, the finite capacity of the recording medium 15 can be utilized efficiently.

The media entry describes the number of playlists.

After the media entry has been read and interpreted, the playlist entry generated for each play list is also read and interpreted to grasp the general contents of the data files of the data file group 13 recorded on the recording medium 15. Will be.

The playlist entry may be given a playlist name which is determined as simply as possible as to which data file the playlist is composed. It becomes easier to grasp the contents of the recording medium 15 by the user.

The play list information recording position of the play list may also be described in the play list entry. When the playlist is selected, the detailed information of the contents can be read and interpreted.

In each play list, a content list listing (1) the number of data files and (2) file entries in reproduction order for each kind of data is described as play list information.

For example, when the recording medium 15 is to be played back in a playback device capable of playing back only audio data, the contents of the file entry need only be confirmed with respect to the music data. Since the number of data files is described for each data type, it is possible to immediately determine whether or not there is a data file that can be reproduced.

In the file entry, file size, data file name (data files registered multiple times may be registered with different names), file type, file recording position information, copyright information, and the like are registered as common information regardless of the type of data file. .

The file recording position information is described using, for example, the physical position address (LSN (Logical Sector Number, etc.) in the case of CD-R) of the recording medium on which the first 1 byte of the file is recorded. Doing so directly accesses the location and reads the file without interpreting other information. For this reason, the data file can be read quickly (for example, the waiting time until the start of reproduction is reduced).

Of course, collective file recording can be performed even when the physical address is unknown at the time of generating the description file 16. Therefore, the relative position at a specific position can be calculated. And by using such information, the data file can be read quickly.

Information about the contents of the data file varies depending on the type of data file. When the data file stores audio data, the reproduction time, data rate, compression method information, sampling frequency, number of channels, and the like are registered. When the data file stores the image data, the reproduction time, data rate, compression method information, image size, frame rate, information about audio data (which should be reproduced simultaneously with the image data), and the like are registered. When the data file stores still image data, compression method information, image size, information on a shooting situation (shutter speed, aperture, focus, use filter, gamma correction, and the like) are registered.

Information about the contents of the data file is information described also inside each kind of data file. However, when displaying a data file recorded on the media by the playback apparatus, it is very time consuming to read or interpret each data file. By gathering information about the contents of the data file in one place, a high speed list display using these information is possible. In addition, determination of whether or not the data file can be reproduced by the reproduction apparatus, retrieval using such information, etc. can be performed at a very high speed.

Of course, as information about the contents of the data file, (1) when the data file stores music data or video data, text information (name, URL of the relevant Internet site, Location, date and time information), and (2) when the data file stores still image data, information such as the model name of the photographed camera, the location of the photographing, the date and time of the photographing, and the comment (text May be described in the entry as text information).

The text information may be described in the form of a combination of a text data entity, a code representing the content of the text, a language designation, and a text data length. In addition, the link destination information of the link files 17a and 17b (refer to FIG. 3) may be described in the form which combined the code, file type, text data length, and link destination designation which show the content of a link file.

A playback device that can display such properties can make it easier to grasp the contents of the data file. It is also possible to further increase the accuracy of the fast search.

In the text entry, for example, the number of text information to be described for each data file is registered. Each text information is described in the form of a combination of a code representing the content of the text, a text information length, and a text information entity.

When the data file relates to still picture data such as an album jacket, a composer or a performer, or a photograph of a photographer, a link entry in which link file information about a thumbnail image or the like is described may be provided. In a reproducing apparatus capable of displaying such data, it becomes easier to grasp what content the file is.

More specifically, in the link entry, for example, the number of link files set for each data file is registered. At this time, a format in which a code, file size, file type, file registration position information, and copyright information (if necessary) are combined may be used.

As media information about the entire media, a name given to the media (sometimes a short name is attached), data added to the media (a picture on the surface of the media, a picture on the media case, a reflection that can be carried with the media) leaflet, etc.), the name of the media creator, and the date and date of creation of the media. In addition, when a short name is attached, the display can be recognized at a glance even in a playback device that can not display a long name because the display screen is small and a playback device that performs scroll display.

The various data described above may be embedded in the description file 16 (for example, all may be described in the media entry, the data entity is recorded in a different part from the media entry in the description file 16, and in the media entry). May only describe link information to the other part). In addition, in the above-mentioned various data, a data substance may be recorded in the recording medium 15 as a separate file, and the description file 16 may describe only the link information to that separate file.

If the play list name is given the short name as described above, the display can be recognized at a glance even if the size of the display screen on the playback device side is small.

The number of data files for each data type may be described as playlist information or may be described in a playlist entry.

The file format of the description file 16 may be a format similar to HTML, or may be a format in which information assigned to a predetermined position having a predetermined predetermined length is described.

The number of files of the description file 16 may be one or plural. In the case where the description file 16 is classified into a plurality of files, only necessary files can be used in accordance with the function of the playback apparatus, so that unnecessary data interpretation is unnecessary.

The structure of the text entry or link entry may also be arbitrary.

(Second embodiment)

6 (a) which is an explanatory diagram of the guide audio data file of the second embodiment of the present invention, and FIG. 6 which is an explanatory diagram of the time table 51 of the guide audio file of the second embodiment of the present invention. The configuration of the recording and reproducing system of the present embodiment will be described with reference to FIG.

The configuration and operation of the recording and reproducing system of this embodiment are similar to the configuration and operation of the recording and reproducing system of the first embodiment described above. Therefore, the following will mainly describe the difference between the two.

As shown in Fig. 6A, the guide audio data file of the present embodiment is a file in which the information to be displayed is filed in a format capable of audio output, and is one of the data files of the data file group 13 '. The guide audio data file is linked to each play list or the above-mentioned media information.

More specifically, one guide audio data file for sequentially reading the data file name (see FIG. 6A) is linked to each play list (or its playlist entry) or media information.

In the timetable 51 of the guide audio file, as shown in Fig. 6B, which data file (or play list) name or information is allocated from t _k seconds to t _n-1 seconds? Information for representing (k = 0, ..., n) is described. Of course, such information may be described in the inside of the guide audio data file (header section or the like).

In the playback apparatus (see FIG. 6C) of this embodiment, the data file and the guide audio file output means 54 reproduce the guide audio file.

When the instruction timing detection means 53 inputs a selection instruction of the data file that the user wants to reproduce from the outside while the guide audio file is being reproduced, the timing timing detecting means 53 analyzes the time table for performing the playback of the guide audio file. Input to output file selecting means 52.

The timetable analysis and output file selecting means 52 refers to the timetable 51 of the guide audio file on the recording medium 15 ', and according to the timing at which the guide audio file is reproduced, the user described above. Selects the data file to be played back appropriately.

The data file and guide audio file output means 54 reproduces the data file selected by the timetable analysis and output file selection means 52.

The playback apparatus of this embodiment is suitable for the case where there is no display function (or poor display function). More specifically, a reproduction apparatus for mainly reproducing an audio data file without a display function is assumed. By creating a guide voice data file in the same format as a reproducible voice data file, the user can be notified of the contents of the recording medium 15 'with almost no hardware such as a display for display.

Of course, the data stored in the guide audio data file may be data of characteristic melody of the data file (when the data file stores music data) or data to which information other than the data file name or play list name is added. .

In the above, the first to second embodiments have been described in detail.

In the recording and reproducing system of the above-described embodiment, the recording apparatus recorded, and the reproduction apparatus composed of a device different from the recording apparatus reproduced.

However, the recording and reproducing system of the present invention may be a system in which the recording and reproducing apparatus are integrated.

Of course, the playback device may be large and easy to see, such as a color TV monitor, or may be small, such as a portable playback device, capable of displaying only black and white, or unable to display an image without a monitor.

In addition, even when the playback apparatus has only a small monitor, for example, the data file may be selected quite easily by displaying the data file name. For example, when data file names are read one by one, a desired data file name is read, and the waiting time until the data file is selected may be longer. If the data file name is displayed, this waiting time becomes unnecessary.

In addition, the recording and reproducing system of the above-described embodiment was provided with a recording apparatus in which write file management means, file recording means, and internal storage means for storing data files are integrated.

However, the recording and reproducing system of the present invention may be a personal computer provided with a CD drive as file recording means and a hard disk as internal storage means. At this time, the write file management means can be realized by using a program.

Of course, recording may be performed by using a program such as a computer or a microcomputer, the recording result may be recorded on a recording medium such as a floppy disk, and then another independent system may play back.

Here, the case of recording and using the recording result on a recording medium such as a floppy disk will be described in more detail.

The program is recorded using this physical format.

The floppy disk FD is stored in the floppy disk case FDC as shown in FIG. 7B, which is an explanatory view of the floppy disk case FDC for storing the floppy disk FD according to the embodiment of the present invention. .

In this way, the floppy disk FD can be safely transported while being protected from dust and external shocks.

The recording and reproducing of the program to the floppy disk FD is performed using the recording and reproducing system as shown in Fig. 7C, which is an explanatory diagram of the recording and reproducing system of the embodiment of the present invention.

More specifically, by connecting the floppy disk drive FDD to the computer system CS, it is possible to record and reproduce a program using the floppy disk FD.

The floppy disk FD is built-in and withdrawn via the floppy disk insertion port FDI.

When recording is performed, the computer system CS writes the program to the floppy disk FD using the floppy disk drive FDD.

When playback is performed, the floppy disk drive FDD reads out the program from the floppy disk FD and transfers it to the computer system CS.

In addition, although the case where a floppy disk is used as a recording medium was demonstrated above, the same also applies to the case where an optical disk, a memory card, a CD-R, etc. are used as a recording medium.

In this way, the centralized recording of the necessary related information allows the contents of the recording medium to be displayed quickly by only accessing one location on the recording medium and reading the data collectively.

In addition, since various related information can be displayed at the same time, it is possible to easily grasp the contents of each data file and easily find the data file to be reproduced.
