Description

  INDUSTRIAL APPLICABILITY The present invention can acquire and reproduce various contents composed of sound data and video data by communication like a portable music player, a mobile phone, or a desktop or notebook computer mainly used at home. The present invention relates to a content list management system that manages communication terminals and content in a list format.

  In recent years, there has been a remarkable increase in communication network speed and cost. As a result, the purchase of CDs (Compact Discs) that have been conventionally required for listening to music tends to decrease. Then, instead of purchasing a CD, there is an increasing tendency to receive a music distribution service using a communication network and to view purchased digital content.

  In addition, with the spread of mobile phones, personal handy-phone systems (PHS), personal digital assistants (PDAs), personal computers or portable music players, sound data including music, novel reading, rakugo, movies, drama It has been changing to a lifestyle of storing and playing back video data including Such an electronic device, unlike a content playback device such as a conventional audio device, uses a technique of storing and playing back content composed of sound data and video data, so that a desired content can be selected from a plurality of stored content. The operation to select the content is required. Therefore, a list of contents is displayed on the display unit of these electronic devices, and the contents to be played back are selected. Therefore, a content list or a play list for reproduction (play) is required.

Therefore, a system has been proposed in which a server side creates a playlist based on a request from a user of each communication terminal and sends the playlist to these users (see, for example, Patent Document 1). In this proposal, the user can easily receive a desired content by a simple operation without the electronic device on the side including the playlist having a large-capacity storage device for storing the content.
Japanese Patent Laying-Open No. 2003-50588 (paragraphs 0008 to 0010, FIG. 1)

  However, miniaturization and increase in capacity of various storage devices typified by semiconductor memories are rapidly progressing, and it has become natural that a large-capacity storage device is prepared for electronic equipment. In such a situation, downloading content to be played each time based on a playlist or content list acquired from a server takes time for that, and content such as music cannot be played immediately. There is an inconvenience. In particular, when downloading multiple songs or downloading large-capacity content such as movies, it is cumbersome for the user to access the download site for each content and repeat the download specification. There is also a waste of time while looking at the operation panel from the end to the playback.

  On the other hand, with the spread of digital broadcasting of television and radio, many communication terminals as electronic devices capable of receiving these have also appeared. These communication terminals can store many high-quality music and videos in a large-capacity storage device. Thereby, the user of each communication terminal can touch the newest content quickly. However, there is a limit to the content information collected by one user, and it is desirable to store the content required by each person using a playlist or content list that covers various types of content.

  Conventionally, for this purpose, there are magazines, television programs, and radio programs that indicate rankings according to sales of music CDs. However, such ranking information based on the release of a CD has a problem that music that can be obtained only through a communication network including the Internet is excluded, and it is difficult to obtain the latest information.

  Accordingly, an object of the present invention is to transmit a list of contents to be played back by the user, acquire a communication terminal that can be used to create the latest content list, and acquire information from such a communication terminal, and perform communication for each communication terminal. An object of the present invention is to provide a content list management system that can be returned as a content list common to terminals.

A content storage means for storing content, and (d) a terminal-side content list to which content specifying information for specifying the content of each content received and stored on its own device side is added, comprising a list of contents stored in the content storage means (E) a reproduction content selection unit that selects desired content from the terminal side content list created by the terminal side content list creation unit and reproduces the content by the content reproduction unit; (F) Created by terminal-side content list creation means And it is equipped with a terminal side content list sending means for sending a terminal-side content list as the terminal-side contents list of the own device in the communication network to the communication terminal.

  That is, in the present invention, the communication terminal includes content receiving means for receiving content from the outside. The content receiving means may be a wireless receiving means such as a television receiving circuit or a radio receiving circuit, or may be a network such as a LAN (Local Area Network). A player connected by USB (Universal Serial Bus) or a receiver as described above may be used. That is, all information sources other than the communication terminal body are targeted. The communication terminal itself is provided with means for storing and reproducing these contents. The content storage unit and the content reproduction unit may be external devices. The terminal-side content list creating means creates a terminal-side content list that includes a list of contents stored in the content storing means and to which content specifying information for specifying the contents of each content received and stored on the own device side is added. The user can reproduce the content on the communication terminal using the terminal-side content list, but can also transmit the content to the communication network as a terminal-side content list of the own apparatus using the terminal-side content list sending means. By collecting the terminal-side content list, it is possible to create a content list that can be used in common by a plurality of communication terminals.

  In the invention according to claim 8, (b) the communication terminal according to any one of claims 1 to 7, and (b) connected to the communication network, and sent from the terminal-side content list sending means of each communication terminal. Terminal-side content list receiving means for receiving the terminal-side content list, content list totaling means for totaling the terminal-side content lists of a plurality of communication terminals received by the terminal-side content list receiving means, and the content list totaling means The content list management system is provided with a content list management server provided with a total content list transmission means for transmitting the total results to the communication network as a total content list.

By preparing a content list management server that distributes to desired ones of communication terminals, a content list management system including communication terminals is realized.

  As described above, according to the present invention, each communication terminal can create a terminal-side content list and develop its contents without placing a special burden on the user. Moreover, the content list management server aggregates the terminal-side content list (user-side playlist) of each user's communication terminal to create a total-side content list (server-side playlist), and provides these to the desired communication terminal. Therefore, it is possible to create a content list in which the latest information is collected more universally based on a multi-side terminal-side content list collected from a plurality of communication terminals. As a result, it is possible to quickly and accurately notify the desired category of contents that the user does not know, and to download and utilize them.

Of course, the users of the _first to n-th mobile terminals 102 _{1 to} 102 _n can also select, for example, a desired piece of music from the newly acquired server-side playlist and purchase it independently from the content server 104. . However, by obtaining via the playlist management server 103, it is possible to realize simplification of processing including settlement.

  The playlist management server 103 is also provided with an input / output control unit 138. The input / output control unit 138 constructs a database for managing playlists in the management database 106 as an external storage device.

Hereinafter, a description will be given of the case where the user performs the management of the first mobile terminal 102 ₁ of the music as an example.

FIG. 4 shows how the user-side playlist is updated in the first portable terminal. This will be described with reference to FIG. The first mobile terminal 102 _1, music recording reproducing unit 118 is monitoring whether to start playing of the music (step S201). When the user operates the operation input unit 115 to start the reproduction of the music (Y), it is monitored whether the reproduction has been performed for a predetermined time t ₁ or more (step S202). Here, the time t ₁ can be adjusted by the user from 0 seconds to an arbitrary number of seconds. For example, 30 seconds is set as the default value.

If the playback of the music piece is stopped only after the time t ₁ is played back (step S202: N, step S203: Y), the process is stopped and registration in the user-side playlist 121 is performed. No (return). This may be the case when the user starts listening to the song but finds it is not a favorite song, or the user may hear it again, such as when the singer or conductor is different from the one expected. This is to exclude those that do not have from the playlist registration target. Of course, when the time t ₁ is set to 0 seconds, all the songs that have started to be listened to are registered in the playlist.

If playback has been performed even after time t ₁ has elapsed since the start of playback of the music (step S202: Y), has the main control unit 111 registered the music in the user-side playlist 121 of the playlist processing unit 120? It is checked whether or not (step S204). As a result, if the song does not exist in the user-side playlist 121 (Y), the song is added to the user-side playlist 121 (step S205), and the process is terminated (return). If the same musical piece already exists in the user-side playlist 121 (step S204: N), the process is terminated as it is (return).

When the user subsequently starts playing another piece of music, the process from step S201 is started again. In this way, when the user listens to new music pieces for a predetermined time t ₁ or longer, these are registered in the user-side playlist 121.

  Note that the registration process to the user-side playlist 121 can be performed by the main control unit 111 in parallel with other processes. Therefore, the music obtained by the broadcast is registered in the user-side playlist 121 in a state where the user turns on the digital television receiver 117 shown in FIG. 2 or a digital radio (not shown). be able to.

  In the process of FIG. 4, the list of songs is simply registered as the user-side playlist 121, but the number of times the user listened to each song and the date and time at which the user listened are also registered, or played back for a certain period or longer You may make it exclude the music which is not done from the list.

FIG. 5 shows a part of the registered contents of the user-side playlist. The user-side playlist 121, the user at the first mobile terminal 102 sequentially registered to play in ₁ shown in FIG 1, Song, music information such as the artist name is recorded for each song. Although not shown in this figure, the user-side play list 121 may also record the above-described registration date and time and the number of reproductions. This is because, when various server-side playlists are created on the playlist management server 103 (FIG. 1) side, they may be required as supplementary information.

  When incidental information representing the content is sent through digital television broadcasting or digital radio broadcasting, the corresponding piece of music information is added to the user-side playlist 121. Of course, the user acquires music from another information processing apparatus such as his computer (not shown) or a music download site on the Internet, and plays the music to add it to the user-side playlist 121. I can go.

FIG. 6 shows an example of a state in which the first mobile terminal is receiving a television broadcast. Television broadcast is received by the display unit 114 of the portable terminal 102 ₁ by the digital television receiving unit 117 shown in FIG. When the user listens to an announcement that the desired song is broadcast, the user operates the predetermined key assigned to the recording of the operation input unit 115 at the timing when the broadcast of the song is started, thereby moving the image and the song to moving image data. Can be saved as In addition, when only recording is desired, it is possible to record only the music by operating other predetermined keys.

  In many cases, the song title and singer name are displayed on the insertion screen as a telop when the song is broadcast. In such a case, a key for incidental information input of the operation input unit 115 is operated. The playlist processing unit 120 shown in FIG. 2 is configured so that, when the stored supplementary information includes identification information for each piece of music information such as a song name or artist name, the user-side play information is based on the identification information. Each information to be recorded in the list 121 (FIG. 5) is extracted.

  When such identification information is not attached to the incidental information, the user-side playlist 121 can search and extract code information that matches, for example, a song name or artist name using a built-in dictionary (not shown). Since the user-side playlist 121 can be edited later by the user, information such as a song name or artist name can be added or corrected at this time. The dictionary management server 103 updates the contents of the dictionary as needed.

  The video data or sound data recorded or recorded in this way is temporarily stored in a large-capacity semiconductor memory (not shown) that is detachable and built in or managed by the playlist processing unit 120. . Then, after the music is cut out as necessary, the music described with reference to FIG. 4 is reproduced. At this time, predetermined music is registered in the user-side playlist 121, and the music is stored as music data corresponding to the playlist.

  Therefore, it is not always necessary for the user to repeatedly record or record each piece of music from a television program or radio program. For example, the entire program can be recorded or recorded, and later necessary pieces of music can be edited automatically or manually. Can be extracted by operation. Thereby, it is possible to prevent the beginning portion of the music from being lost due to a recording or a recording operation mistake. However, by providing a delay circuit in the playlist processing unit 120 and recording or recording about several seconds before the recording or recording operation is performed, it is possible to prevent the lack of the beginning portion of the music.

Incidentally, in the content list management system 100 of the embodiment collects the playlist management server 103 to each user-side playlist 121 of the portable terminal 102 ₁ to 102 _n of the first to n shown in FIG. 1, The server-side playlist described above is created. For this purpose, among users of the _first to n-th mobile terminals 102 _{1 to} 102 _n, a user who uses the content list management system 100 transmits a user-side playlist 121 to the playlist management server 103 or a server Make settings to receive the side playlist.

FIG. 7 shows a state of the playlist transmission / reception setting process of the portable terminal. Here, the processing of the _first portable terminal 102 ₁ shown in FIG. 1 will be described, but the processing of the second to n-th portable terminals 102 _{2 to} 102 _n is the same as this. This will be described with reference to FIGS.

The first mobile terminal 102 ₁ of the user operates the operation input unit 115 selects a playlist reception setting mode (step S221: Y). When a mode other than this is set (N), the corresponding other mode is executed. When the playlist transmission / reception setting mode is selected, the playlist transmission / rejection display is performed on the display unit 114 (step S222). Viewing this display, the user operates the operation input unit 115 to input whether or not to transmit the user-side playlist 121 to the playlist management server 103.

  When “Transmittable” is input (step S223: Y), processing for setting a time interval for transmitting the user-side playlist 121 to the playlist management server 103 is performed (step S224). Here, for example, the user operates the operation input unit 115 to input a transmission interval such as every day or once a week. The communication cost for such transmission processing may be borne by the playlist management server 103, or a predetermined service point may be given, thereby discounting the fee when purchasing content such as music. Good.

  When the process of step S224 is completed, a playlist reception availability display is performed on the display unit 114 (step S225). When the user selects not to transmit the user-side playlist 121 to the playlist management server 103 (step S233: N, step S226: Y), the playlist is not performed without performing the transmission interval setting process in step S224. A reception permission / inhibition display is performed (step S225).

  In a state where the playlist reception availability display is performed, the user makes an input indicating that the server-side playlist is allowed to be received from the playlist management server 103 (step S227: Y) or not (step S227: N, Step S228: Y) Input is performed. When an input to allow reception of the server-side playlist is performed (step S227: Y), processing for setting a reception interval from the playlist management server 103 is performed (step S229). The playlist management server 103 provides the user with a privilege such as free communication of the server-side playlist once a week when content such as music is purchased once or more in January, for example. Can do.

When the reception interval setting process of step S229 is completed, when the portable terminal 102 subsequently receives the playlist, a display setting process for determining whether or not to immediately display the playlist is performed (step S230). Thereafter, the first portable terminal 102 ₁ attaches user identification information such as its own ID (Identification) and transmits the playlist transmission / reception setting contents to the playlist management server 103 (step S231). If reception of the server-side playlist is disabled in step S228 (Y), the setting contents are similarly notified to the playlist management server 103 without performing the processing in steps S229 and S230. (Step S231). Information such as the user's gender, age or date of birth, and place of birth can be added to the user specifying information.

The playlist transmission / reception setting process of the mobile terminal shown in FIG. 7 can be performed as many times as necessary by the user, and thus the newly set content can be notified to the playlist management server 103. The playlist management server 103 is based on various server sides based on the user-side playlist 121 sent from a terminal that allows transmission of a playlist among the _first to n-th mobile terminals 102 _{1 to} 102 _n. Create a playlist.

8 to 10 show some examples of the server-side playlist. Of these, FIG. 8 is a hit playlist of music. This is based on the notifications of the _first to n-th mobile terminals 102 _{1 to} 102 _n , and the user-side playlist 121 (FIG. 2) as a whole has the highest number of playback times or 1 in the largest number of user-side playlists 121. It is shown as the latest result in order from the music located in the place. The results are accumulated with reference to the registration or update date and time of each piece of music in the user-side playlist 121 sent from the mobile terminal 102.

  FIG. 9 shows a hit play list of music that is totaled for the entire user every month. On the other hand, FIG. 10 shows hit playlists by user's age group. Aggregation such as by user's age and gender is created using the above-described user specifying information. Various server-side playlists as shown in FIGS. 8 to 10 are stored in the management database 106 shown in FIG. These are transmitted to the portable terminal 102 of the user who has requested the analysis in the playlist management server 103 and the transmission of the server-side playlist in steps S227 and S231 in FIG.

FIG. 11 shows a state of playlist distribution processing for the mobile terminal by the playlist management server. The playlist management server 103 periodically performs playlist distribution processing at predetermined times multiple times a day for the first to _n-th mobile terminals 102 _{1 to} 102 n shown in FIG. . When the distribution time of the playlist comes (step S241: Y), the terminal to be distributed for the playlist to be distributed this time is searched based on the distribution request contents of the _first to n-th mobile terminals 102 _{1 to} 102 _n . (Step S242). Then, the playlist is transmitted to all mobile terminals 102 to be distributed this time (step S243).

FIG. 12 shows the flow of playlist reception and display processing on the mobile terminal side. The first portable terminal 102 ₁ will be described as an example with reference to FIGS. 1 and 2. When the communication control unit 113 of the first mobile terminal 102 ₁ receives the server-side playlist from the playlist management server 103 (step S261: Y), the main control unit 111 receives the server-side playlist on the display unit 114. A reception notification icon for notifying this is displayed (step S262).

Playlist processing unit 120 in this state, checks whether the first mobile terminal 102 ₁ in step S230 of FIG. 7 is performed immediately display setting server-side playlist on the display unit 114 (step S263). When such display is performed (Y), the received server-side playlist is immediately displayed on the display unit 114 (step S264). In this state, if desired music from among the first mobile terminal 102 ₁ is displayed server-side playlist to end the display of either selected (step S265), or the server-side playlists for download (Step S265: N, Step S266) is waited for.

  FIG. 13 shows an example of a download selection screen displayed on the display unit of the mobile terminal. Here, a hit play list is displayed on the display unit 114, and information such as the name of each song is displayed in order from the hit song. A check box 151 for designating music to be downloaded is arranged on the left side of each music diagram. The user moves the cursor 152 to a desired check box 151 by operating a pointer (not shown) of the operation input unit 115 with a finger, for example, and designates whether or not downloading is necessary for each song.

In this way, when download of a desired music piece is designated from the server-side playlist (step S265: Y in FIG. 12), download time setting processing is performed (step S267). The user can select either a setting for immediate download or a setting for determining the download date and time. The reason why the download can be made at a fixed date is to postpone the download of the music later when the battery of the _first mobile terminal 1021 is low or during a large-capacity data communication. This is to cope with a case where there is a need, for example, when there is a request for performing a batch download using a night download discount.

  When the download time setting process is performed, the main control unit 111 notifies the playlist management server 103 of such a download request set by the user using the communication control unit 113 (step S268). Thereafter, the display of the display notification icon is deleted (step S269). Even when selection for downloading music is not performed in step S265 and the end of the server-side playlist selection process is instructed in step S266 (step S266: Y), the display notification icon is deleted. (Step S269).

  On the other hand, if the server side play list is not set to be displayed immediately in step S263, the process is temporarily terminated without erasing the display notification icon (return). After that, when the user operates the operation input unit 115 to request display of the server-side playlist (step S270: Y), the process proceeds to step S264, and the server-side playlist is displayed.
