Description

  The present invention relates to a playback device that can play back a content selected from a plurality of stored content data and that can edit index data.

2. Description of the Related Art In recent years, a device that draws out music data from a music CD and stores it on a hard disk together with album information such as a title and a singer's name, and plays the music data designated by the user from the stored music data has attracted attention. Yes. Since the album information is not stored in the music CD, the album information can be acquired via, for example, the Internet using a server that manages a music database including album information (for example, (See Patent Document 1.)
However, it is a heavy burden on the user for the user to search and specify desired music data from a lot of music data (for example, hundreds to thousands of music data).

Thus, a function of creating an album list for each artist name using the artist name as a key is considered. In addition, there is a function that the artist name can be edited to the user's favorite name. For example, you can change it to a nickname or change it to your own name. These two functions are significant functions.
http://support.microsoft.com/default.aspx?scid=kb;en;418677

  However, the album list creation function by artist name creates an album list by comparing the character string of the artist name, so even if it is the same artist, even if the character string is slightly different, it is recognized as a different artist, The problem of creating another album list is inherent.

  In addition, since the artist name editing function manages only the edited data as the editing result, there is a problem that when the data before and after editing coexist, they are treated as completely different data.

  As a result of the above two problems, the combination of the album name creation function by artist name and the artist name editing function causes the following problems. That is, for example, when the artist name “XXX” is originally edited to “YYY” or “ZZZ”, the original name “XXX” and “YYY” or “ZZZ” are recognized as the same artist name. Can not. Thus, for example, an album is left as “XXX”, another album is edited (changed) to an artist name “YYY”, and another album is edited to an artist name “ZZZ” ( In the case of (changed), it is treated as if there were three other artists in spite of being actually one artist “XXX”, and “XXX”, “YYY”, “ZZZ” The multiple album lists are created.

  In addition to such a situation of creating an album list, for example, when considering inputting an artist name by voice and displaying the corresponding album name or song name, the following inconvenience can be written. That is, for example, if you want to display the album name registered with “BBB” or the song name included in the album, but forget that the user has registered with “YYY”, no matter how much “XXX” Even if the artist name “ZZZ” is entered, the corresponding album name is not displayed. Accordingly, unless the artist name is entered and the artist name is entered, the corresponding album name or the like cannot be displayed.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a playback apparatus that can search content data using index data before editing even when index data is edited. .

  According to the playback device of the present invention, the storage unit stores a plurality of content data and the index data of the content data in association with each other, and the playback unit is designated among the stored content data. Content data can be reproduced. Then, when a search word for designating content data to be reproduced is input by the input means, the control means, based on the input search word, matches information from the index data stored in the storage means. And the reproducing means reproduces the content data corresponding to the adapted index data.

Here, the playback device of the present invention further includes instruction receiving means for receiving various instructions from the user , and when receiving an editing instruction for editing the index data by the instruction receiving means, the control means includes: The index data is edited based on the received editing instruction, and stored in the storage means so that the index data before and after the editing can be associated. In other words, for example, instead of deleting the artist name before editing and rewriting it with the artist name after editing (overwriting) as in the past, the artist name before editing and the artist name after editing are also retained. The artist name is stored so that it can be associated with the name before and after editing. Then, when a search word is input, the control means executes a search for any index data before and after editing.

  Thus, since the index data before and after editing are targeted for search, for example, even after editing the artist name, it is possible to search even if the artist name before editing is entered, which occurred in the prior art. Inconvenience can be solved.

  Moreover, as an input means, the audio | voice which the user uttered, for example, may be comprised so that the search word used for a search may be selected and input from the recognition result. This is particularly effective when the playback device is mounted on a vehicle. In other words, considering that the driver of the vehicle inputs via the input means, if voice input is possible instead of input by manual operation, the driver does not release his / her hand from the driving device such as the steering wheel. This is because an instruction can be given to the playback apparatus and safety is increased, so that the utility value is high.

  Although various types of content data are conceivable, for example, at least music data may be included. The index data in that case may include at least the artist name corresponding to the music data. This corresponds to a case where music data is read from a so-called music CD and stored in a hard disk or the like. Of course, image data and music data may be a set.

  When copying data such as music CDs in this way, the user may edit the artist name or the album name according to his / her preference. If you can understand the identity of the artist name and album name, you can search appropriately.

  When the index data includes not only the artist name but also the name of an album composed of a plurality of music data, the control means is designated by the instruction accepting means and corresponds to the artist name. It is convenient if there is a function that can receive an instruction to create an album list in which album names to be compiled are received and can create an album list. In this case, according to the conventional technique, it is impossible to determine that the artist names before and after editing are substantially the same, so a plurality of album lists are created. On the other hand, the control means extracts the album name corresponding to the designated artist name, and if the designated artist name is the name after editing, also extracts the album name corresponding to the name before editing. If an album list is created, only one album list for substantially the same artist name is created.

In addition, a computer according to claim 6 may be used to cause a computer to function as control means of the playback apparatus according to any one of claims 1 to 5.
Such a program can be used by recording it on a computer-readable recording medium such as a magnetic disk, a magneto-optical disk, a memory card, etc., and loading and starting the computer as necessary. It can also be used by loading and starting up via a network. Accordingly, it is possible to easily improve the function.

The touch panel and the display unit 26 are laminated and integrated. There are various types of touch panels such as a pressure-sensitive method, an electromagnetic induction method, a capacitance method, or a combination of these methods. It may be used.

  The external information input / output unit 24 is connected to an antenna (not shown) and receives traffic information from a VICS center (not shown) via the antenna. The received traffic information is sent to the control circuit 29 and used when setting a guide route. In addition, it is connected to the Internet via a car phone or a mobile phone so that various information can be acquired.

  The CD / DVD drive 25 is a device for inputting various data stored in a CD-ROM or DVD-ROM (not shown). Examples of the CD-ROM or DVD-ROM to be input with the CD / DVD drive 25 include map data (road shape data, road width data, road regulation data, terrain data, mark data, intersection data). And so-called map CD or DVD storing facility data, etc., and so-called music CD storing music data.

  The music data read from this music CD can be stored in the hard disk 23. Further, in order to facilitate the user's selection when reproducing the music data, the music data can be stored in the hard disk 23 in correspondence with the index data. The index data includes artist name / album name / genre data. These index data are acquired via the Internet from a server that manages the index data. This point will be described later. Note that map data read from a map CD or DVD, sound data for facility guides / various guidance, and the like can also be stored in the hard disk 23.

  The display unit 26 is a color display device such as a liquid crystal display, an organic EL display, or a CRT, and any of them may be used. On the display screen of the display unit 26, a mark indicating the current location identified from the current vehicle position detected by the position detector 21 and the map data input from the CD / DVD drive 25, a guide route to the destination, and a name Additional data such as landmarks and various facility marks can be displayed in an overlapping manner. Also, facility guides can be displayed.

  The voice output unit 27 can output a guide voice or the like as a result of processing executed by the control circuit 29 based on facility guides or various guidance voice data stored in the hard disk 23.

  The control circuit 29 accesses a predetermined server via the Internet via the external information input / output unit 24 based on TOC (Table of Contents) information read from the music CD, and acquires corresponding index data. Then, the music data and the index data are stored in the hard disk 23 in association with each other. As described above, this index data is artist name / album name / genre data, etc., and these index data can be edited by user operation. That is, by operating the operation switch group 22, for example, the artist name can be changed to a nickname or a name omitted. Since it is for personal enjoyment, by changing the artist name according to his / her preference in this manner, selection can be facilitated when selecting music data to be reproduced, or the user's hobby can be satisfied. As will be described in detail later, for example, when a plurality of CD albums are stored in the hard disk 23, an album list for each artist can be created. In this way, if an artist name is specified, all albums corresponding to that artist are listed, which is convenient when selecting a playback target.

The schematic configuration of the navigation device 20 has been described so far, but correspondence between each part of the navigation device 20 and the terms described in the claims is shown.
The hard disk 23 corresponds to storage means, the operation switch group 22 and the microphone 28 correspond to input means and instruction reception means, and the control circuit 29 corresponds to reproduction means and control means.

  Next, among the processes executed by the control circuit 29, the description of the navigation-related processes is omitted, and the editing process of the index data of the music data stored in the hard disk 23 is described with reference to FIGS. explain. Here, the artist name editing function and the album list creation function for each artist name will be described. In describing each function, the prior art will be described first, and then the present embodiment will be described. The advantages of each function in this embodiment will be described by comparison.

[Artist name editing function]
(1) First, conventional artist name editing will be described.
Since the conventional artist name editing function manages only the data after editing as the editing result, there is no association between the data before and after editing, and when the data before and after editing coexist, they are treated as completely different data. An example is shown in FIG.

  For example, in the user operation [1], a music CD called [AAA] of an artist called “Yamada Koro” is registered. In this case, the name on the display is the artist name “Yohiro Yamada” and the CD name is “AAA”. The internal management data is the artist name “Yohiro Yamada” and the CD name “AAA”, as is the name on the display. In this case, the internal management data is handled in a state where one music CD of one artist “Yamada Koro” is registered.

  Next, in the user operation [2], the name “Yamada ○” registered in [1] was changed to the nickname “Yama-chan”. The name on the display is the artist name “Yama-chan” and the CD name is “AAA”. The internal management data has the artist name “Yama-chan” and the CD name “AAA”, as is the name on the display. The internal management data in this case is handled as a state where one music CD of one artist “Yama-chan” is registered.

  Next, in the user operation [3], a music CD called “BBB” of “Yamada Koro”, which is a different music CD from [1], was registered. The names on the display will be the artist name “Yamada” and the CD name “BBB” in addition to the already registered artist name “Yama-chan” and CD name “AAA”. In this case, the internal management data is the same as the name on the display, and the internal management data is the same as the original, but two music CDs of two artists “Yama-chan” and “Yarou Yamada” are registered. It is treated as a state.

  Next, in user operation [4], the name “Yamada” registered in [3] is changed to “Yamada”. The name on the display is the artist name “Yamada” and the CD name “BBB” in addition to the already registered artist name “Yama-chan” and CD name “AAA”. The internal management data in this case is the same as the name on the display. The internal management data is originally the same, but two music CDs of two artists “Yama-chan” and “Yamada” are registered. Treat as a state.

  Next, in the user operation [5], a music CD called “CCC” of “Yohiro Yamada” different from [1] and [2] was registered. The names on the display are the artist name “Yama-chan”, the CD name “AAA”, the artist name “Yamada”, the CD name is “BBB”, the artist name “Yo Yamada”, and the CD name. Becomes “CCC”. The internal management data in this case is the same as the name on the display, and this internal management data is originally the same, but the music CDs of the three artists “Yama-chan”, “Yamada”, and “Yo Yamada” Treat as 3 registered.

  In this way, in the case of the conventional editing method, since only the edited data is managed, the edited data becomes the internal management data, and even if the same artist is renamed, it is managed as a different artist. End up. In other words, even though they are actually the same artist, they are treated as if there are three artists, “Yama-chan”, “Yamada”, and “Yo Yamada”.

(2) Next, artist name editing in this embodiment will be described.
According to the artist name editing function in the present embodiment, by managing both “name before editing” and “name after editing” of artist names that can be edited, it is possible to associate the artist names before and after editing with each other. . An example is shown in FIG. User operations [1] to [5] in FIG. 3 are the same as user operations [1] to [5] in the conventional case in FIG.

  For example, in the user operation [1], a music CD called [AAA] of an artist called “Yamada Koro” is registered. In this case, the name on the display is the artist name “Yohiro Yamada” and the CD name is “AAA”. The internal management data is the artist name “Yohiro Yamada” and the CD name is “AAA” in the same way as the name on the display. For the artist name in this internal management data, the artist name before change and the artist name after change are all. Remember. In this case, since there is no change in the artist name, “Yohiro Yamada” is stored as the artist name before the change. The internal management data in this case is handled as a state in which one music CD of one artist “Yamada Koro” is registered.

  Next, in the user operation [2], the name “Yamada ○” registered in [1] was changed to the nickname “Yama-chan”. The name on the display is the artist name “Yama-chan” and the CD name is “AAA”. In the internal management data, “Yamada Koro”, the artist name before the change, and “Yama-chan”, the artist name after the change and the display name, are stored as the artist name, and the corresponding music The CD name is “AAA”. The internal management data in this case is handled as a state where one music CD of one artist “Yama-chan” is registered.

  Next, in the user operation [3], a music CD called “BBB” of “Yamada Koro”, which is a different music CD from [1], was registered. The names on the display will be the artist name “Yamada” and the CD name “BBB” in addition to the already registered artist name “Yama-chan” and CD name “AAA”. The artist name “Yaro Yamada” of the added music CD is already held as the artist name before the change in the internal management data. Therefore, the artist name is not added, and only “BBB” added as the CD name is added. That is, both “AAA” and “BBB” are stored as CD names. This internal management data is treated as if two CDs of one artist are registered because it can be understood that “Yama-chan” and “Yohiro Yamada” are the same artist by tracing the pre-edit data. .

  Next, in user operation [4], the name “Yamada” registered in [3] is changed to “Yamada”. The name on the display is the artist name “Yamada” and the CD name “BBB” in addition to the already registered artist name “Yama-chan” and CD name “AAA”. The internal management data in this case additionally stores “Yamada”, the artist name after the change and the name on the display, while leaving the name “Yamada Oro” as the artist name before the change as the artist name. . That is, the changed artist names are “Yama-chan” and “Yamada”, the music CD name corresponding to “Yama-chan” is “AAA”, and the music CD name corresponding to “Yamada” is “BBB”. . Since the internal management data in this case can be understood that “Yama-chan” and “Yamada” are the same artist by tracing the pre-edit data, it is handled as if two CDs of one artist are registered. .

  Next, in the user operation [5], a music CD called “CCC” of “Yohiro Yamada” different from [1] and [2] was registered. The names on the display are the artist name “Yama-chan”, the CD name “AAA”, the artist name “Yamada”, the CD name is “BBB”, the artist name “Yo Yamada”, and the CD name. Becomes “CCC”. The internal management data in this case additionally stores the music CD name “CCC” corresponding to the artist name “Yo Yamada” remaining as the artist name before the change as the artist name. In other words, the artist name before the change is “Yo Yamada”, the artist name after the change is “Yama-chan” corresponding to the music CD name “AAA”, and the artist name before the change is “Yo Yamada” after the change. In addition to the music CD name “BBB” corresponding to the artist name “Yamada”, the music CD name “CCC” corresponding to the artist name “Yaro Yamada” exists as internal management data. The internal management data in this case can be found by tracing the pre-editing data, so that “Yama-chan”, “Yamada”, and “Yo Yamada” are the same artist, so three CDs of one artist are registered. Treat as being done.

[Album list creation function for each artist name]
(A) A case where an album list for each artist name is created in a state edited by the conventional artist name editing described with reference to FIG. 2 will be described.

  The data registration status in this case is as shown on the left side of FIG. In other words, the name on the display is the CD name “AAA” for the artist name “Yama-chan”, the CD name “BBB” for the artist name “Yamada”, and the CD name “Yo Yamada” for the artist name “Yamada”. CCC ". The internal management data is also the same as the name on the display, as if there are corresponding CD names for the three artists. Therefore, when creating an album list, it is determined whether or not they are the same artist by comparing the character strings of the artist names in the internal management data. If they are different, it will be recognized as another artist and will create another album list. In other words, since only the character string comparisons of the artist names “Yama-chan”, “Yamada”, and “Yohiro Yamada” are performed, they are different from each other and are treated as different artists. As a result, as shown on the right side of FIG. 4, for the artist name “Yama-chan”, the CD name “AAA”, for the artist name “Yamada”, for the CD name “BBB”, and for the artist name “Yamada ○ Chiro” Thus, an album list with the CD name “CCC” is created.

(B) Next, a case where an album list for each artist name is created in the state edited by the artist name editing of the present embodiment described with reference to FIG. 3 will be described.
The data registration status in this case is as shown on the left side of FIG. In other words, the name on the display is the CD name “AAA” for the artist name “Yama-chan”, the CD name “BBB” for the artist name “Yamada”, and the CD name “Yo Yamada” for the artist name “Yamada”. For the internal management data, there are “Yamada Koro” as the artist name before the change, and “Yama-chan” and “Yamada” as the artist name after the change. Then, “AAA” as the CD name corresponding to the changed artist name “Yamada ○” → “Yama-chan”, and “CD” corresponding to the changed artist name “Yamada ○” → “Yamada”. “CCC” exists as a CD name corresponding to the artist names “BBB” and “Yohiro Yamada”.

  Then, when comparing the character strings of the artist names in the internal management data when creating the album list, it is determined whether or not they are the same artist in consideration of such a change history. Then, the artist names before the change corresponding to the CD names “AAA” and “BBB” are both “Yamada Koro”, which is the same as the artist name corresponding to the CD name “CCC”, and these three CD names “ It can be determined that “AAA”, “BBB”, and “CCC” are substantially from the same artist. As a result, as shown on the right side of FIG. 5, an album list in which the CD names “AAA”, “BBB”, and “CCC” correspond to the artist name “Yaro Yamada” is created.

In this way, even if the name is different on the display, by considering the change history, it can be recognized that the name is the same artist before the change, and even if the artist name is changed by the user operation, the same artist It is possible to create an appropriate album list. Therefore, for example, when the album list is displayed on the display unit 26, three music CD names “AAA”, “BBB”, and “CCC” are displayed in correspondence with the artist name “Yohiro Yamada”. In this display, the artist name after the change may be written together. That is, the name after the change of “Yama-chan” and “Yamada” is written together with the name before the change of “Yamada ○”, for example, in parentheses.
Also, consider a case where a specific artist name is designated via the operation switch group or the microphone 28 and only the album list is displayed on the display unit while the album list is created. Also in this case, by considering all the above-described change histories, for example, any of “Yamada ○”, “Yama-chan”, and “Yamada” is designated, the corresponding music CD names “AAA”, “BBB”, “CCC” "Can be displayed on the display unit 26.

  In the specific example shown in FIG. 3, since editing is performed only once, there is only one artist name before the change, but for example, if the name has been changed N times, the artist name before the one change is made. What is necessary is just to memorize | store as internal management data so that all the change histories may be known like the artist name before 2 times of change, and the artist name before N times of change. Then, by considering all the histories, it can be determined whether or not the music CDs belong to the same artist, no matter how the user changes the artist name.

Other embodiments will be described below.
(1) In the above embodiment, the description has been given of the case where the artist name of the index data is to be edited, but other index data such as an album name may be used as the editing target.

  (2) In the above embodiment, the apparatus for reproducing music has been described. However, instead of music, a video (for example, a movie or a promotion video), a voice (for example, a novel read or a rakugo), a text (for example, a newspaper) Articles, magazine articles, etc.) may be replayed (displayed). Even in such a case, it is conceivable that the user edits the artist name, the author name, and the like for the content, so the same effect as described above can be obtained. Note that the index data can be appropriately set corresponding to the content data, and the technical idea of the present invention can be applied to any index data that can be edited.

  (3) When the user inputs an instruction or the like to the navigation device 20, the above embodiment is configured to be able to execute either manual input via the operation switch group 22 or voice input via the microphone 28. Yes. These may have only one of the input methods. For example, when the driver is a user as an in-vehicle device, it is convenient that voice input is possible. If voice input is possible instead of manual input, the driver can give an instruction by voice without releasing his / her hand from the driving device such as the steering wheel, thereby improving safety.

  (4) In the above embodiment, the navigation device 20 as an example of a playback device has been described as an example. However, it is naturally possible to realize the device as a device having a playback function without a navigation function.
