As a result, transmission / reception time delays and transmission / reception errors can be prevented, so that content management can be easily and efficiently performed.

Hereinafter, a content transmission / reception technique according to an embodiment of the present invention will be described with reference to the accompanying drawings. Note that the content transmission / reception technology includes a content transmission device, a content transmission program, a content reception device, and a content reception program.
As shown in FIG. 1A, the content transmission / reception technique according to the present embodiment is used when content is transmitted / received between the content transmission device 4 and the content reception device 6 through various networks 2 (for example, the Internet and LAN). For example, contents can be packaged and transmitted / received according to the purpose of use such as type, contents, application, and history.

  In this case, the content transmission device 4 is positioned as a server (a computer that manages content transmission) connected to the various networks 2. As a content transmission / reception method between the content transmission device 4 and the content reception device 6, for example, Either a wired or wireless method may be used. In this case, for example, a mobile phone, a PHS, a PDA, a computer, or the like can be assumed as the content receiving device 6, but in the following description, the mobile phone 6 is assumed as an example of the content receiving device 6.

  In order to package and transmit the content through the various networks 2 as described above, the content transmission device 4 packages and transmits the content through the various networks 2 as shown in FIGS. Content registration means 8 for registering the various contents, and content transmission means 10 for packaging and transmitting the contents according to a predetermined use purpose.

  The content registration means 8 applies, for example, a database that is software for efficiently managing content, or a nonvolatile memory (flash memory) that can electrically erase and rewrite registered content and does not require a backup power source Just do it. In this case, the content is converted into a digital signal or an analog signal that can be electrically processed and registered in the content registration means 8. The content means various multimedia information such as moving images, still images, characters, and voices. In the following description, as an example of the multimedia information, shogi, go, card game, mahjong, Assume information about various games such as pachislot and pachinko. As an example of information about the game, information (monthly Shogi game) that summarizes the game of Go and Shogi (for example, each school's game, celebrity battle, own battle history, etc.), card game, Mahjong, pachislot, It is possible to assume a game record in which a gaming state such as a pachinko is represented by numbers or symbols.

The content transmission unit 10 includes a content extraction unit 12 that extracts content from the content registration unit 8 according to a predetermined usage purpose, a packaging unit 14 that packages the extracted content, and a modulation process that performs modulation processing on the content A unit 16 and a content transmission unit 18 that transmits the modulated content are provided.
As an extraction method by the content extraction unit 12, for example, a setting extraction method for extracting content according to a preset purpose of use and a request extraction for extracting content according to a purpose of use requested by the user of the mobile phone 6 Method can be envisaged.

In the setting extraction method, for example, when content transmission is reserved at the time of contract (when accessing the content transmission device 4), the history is registered (updated) for each user, and content extraction is performed based on the registered (updated) contents. The unit 12 extracts the corresponding content.
Such a history is recorded in the database (DB) 30 of the content transmission device 4 (FIG. 1B). FIG. 3 shows a record example of the history of shogi. In this DB 30, the shogi power and school for each user (A, B) are registered, and the IP address of the mobile phone and the contract are registered. Are registered in association with users. As a result, the user who uses the mobile phone can be specified, and the reliability of content transmission is ensured.

  Here, assuming that, for example, a reservation is made for content transmission of a monthly shogi game, the content extraction unit 12 extracts a corresponding monthly shogi game based on the history of the DB 30. For example, in FIG. 3, since user A has already transmitted monthly shogi games for January to August, content for September is extracted. On the other hand, User B has already sent the contents for 1-4 and June-August, but has not been sent for May, so two contents for May and September are extracted. The

On the other hand, in the request extraction method, for example, as shown in FIG. 1 (f), content extraction is performed by selecting a content request item displayed on the display screen 6a of the mobile phone 6 by the content request means 20 described later. The unit 12 extracts content corresponding to the selected item. In the same figure, the case where the content of the monthly Shogi game is requested is illustrated as in the above-described setting extraction method.
In the setting extraction method and the request extraction method, shogi content in accordance with the user's repulsion registered in the DB 30 may be extracted. If content that is too advanced compared to the user's repulsion is transmitted, it is difficult to maintain and improve the interest of the user for the content because the content cannot be understood. In this case, for example, as shown in the example of shogi in FIG. 4A, the content can be reselected (for example, reselected by the reselect button 32) on the display screen of the transmitted content according to the repulsion level. May be.

The packaging unit 14 operates when a plurality of contents are extracted by the content extraction unit 12 and packages the data as one data so that the plurality of contents are not transmitted individually. Note that, as a packaging method, an existing method that is currently known can be used as it is, and therefore, it is not particularly described here.
The modulation processing unit 16 performs processing for placing various multimedia information such as moving images, still images, characters, and sounds on a carrier wave. By performing such processing, the content can be transmitted from the content transmission unit 18 to the content reception device 6 (mobile phone 6) through the various networks 2. As a modulation method, an existing modulation method that is currently known can be used as it is, so that it is not particularly described here.

  As shown in FIGS. 1D and 1E, the content receiving device 6 (mobile phone 6) includes content requesting means 20 that requests transmission of content according to a predetermined usage purpose, and content reception that receives content. Means 22 and content display means 24 for displaying the received content. The content receiving means 22 includes a content receiving section 26 that receives the content, and a demodulation processing section 28 that performs demodulation processing on the received content. Is provided.

For example, as shown in FIG. 1 (f), the content request unit 20 displays content request items on the display screen 6a of the mobile phone 6, and selects the desired content by operating the cursor key 6b. can do. Here, the case of requesting shogi content (monthly shogi game) is illustrated.
The content receiving unit 22 receives the content extracted by the above-described setting extraction method and also receives the content extracted by the request extraction method by the content requesting unit 20. Specifically, the content extracted by the setting extraction method and the request extraction method and transmitted from the content transmission device 4 is received by the content reception unit 26 in the content reception unit 22 and then received from the carrier by the demodulation processing unit 28. Multimedia information is retrieved.

  Then, the content display unit 24 displays the multimedia information extracted by the demodulation processing unit 28 on the display screen 6 a of the mobile phone 6. The display method in this case can be arbitrarily set according to the user's purpose of use. For example, FIG. 2 (a) shows an example in which a plurality of contents are packaged as multimedia information and transmitted from the content transmission apparatus 4, demodulated by the demodulation processing unit 28, and displayed on the display screen 6a. Yes. Here, monthly shogi games from January to September are displayed at a time. The user can confirm that there is no monthly shogi game for September only by operating the cursor key 6b and selecting a desired item (for example, for September).

  As described above, according to the present embodiment, since a plurality of contents are packaged and transmitted, transmission / reception between the content transmission apparatus 4 and the content reception apparatus 6 can be performed only once. Thus, the amount of content (traffic) on the transmission / reception path (wired or wireless) can be greatly reduced, and overhead can be reduced. As a result, transmission / reception time delays and transmission / reception errors can be prevented.

  Furthermore, according to the present embodiment, content can be packaged and transmitted / received according to the purpose of use of the user, so that content can be managed easily and efficiently. For example, when a user makes a new contract for annual transmission of a monthly shogi game in September, the content request item (for example, monthly shogi game) displayed on the display screen 6a by operating the cursor key 6b of the mobile phone 6 is operated. Is selected (FIG. 1 (f)), the corresponding content is packaged and transmitted from the content transmission device 4, and its contents (all contents from January to September) are displayed on the display screen 6a. (FIG. 2 (a)).

In the conventional content transmission technology, if a new contract is made in September, the monthly Shogi game for September will be transmitted at the same time. The monthly Shogi games for January to August are transmitted individually. In this case, the transmission of the content is complicated and troublesome, and as a result, the content cannot be managed efficiently.
On the other hand, according to this embodiment, even if a new contract is made in September, all the monthly shogi games from January to September are performed by the content extraction unit 12 of the content transmission device 4. These are extracted, packaged, and transmitted from the content transmission unit 18 to the mobile phone 6. For this reason, the content can be transmitted only once, and the content can be managed efficiently. Then, on the display screen 6a, after selecting the desired month (for example, for September), check the contents of the monthly Shogi game for that month (for September) by selecting the “Confirm Content” field. Can do.

  Further, according to the present embodiment, for example, as shown in FIG. 2A, in the state where all the contents are displayed on the display screen 6a, the contents corresponding to other purposes of use are further narrowed down and displayed. You can also. When the “other purpose of use” column is selected on the display screen 6a of FIG. 2A, “other purpose of use” is subsequently displayed on the display screen 6a (FIG. 2B). At this time, if the “hand for each school” column is selected, for example, as shown in FIG. 4 (a), the “hand for each school” for the monthly shogi game from January to September is packaged and transmitted. The contents can be confirmed. In this case, if you want to check the “hands for each school” only for January according to the usage, select “January” on the previous screen (Fig. 2 (a)) and then other usage purposes. If you want to confirm “hands for each school” over multiple months, select the desired month (for example, for January to June) on the previous screen (FIG. 2 (a)). After selection, the “other use purpose” column may be selected.

When confirming the contents of “one hand for each school”, by selecting the school selection buttons 34, 36, and 38 (FIG. 4A) displayed on the display screen 6a, for example, FIGS. As shown in d), a hand for each school (for example, × flow, Δflow, ○ flow) can be specifically displayed.
In this case, by selecting the reselection button 32 on the display screen 6a, it is possible to confirm the “hand for each school” corresponding to the repulsive force (stage rank). In FIG. 4A, it is assumed that the “step of each school” at the second level is confirmed.

Further, in the state where the “other purpose of use” column is selected on the display screen 6a of FIG. 2A and “other purpose of use” is displayed on the display screen 6a (FIG. 2B), for example, “master If the “battle” field is selected, for example, as shown in FIG. 2 (c), it is possible to check the master battles held every month from January to September.
It should be noted that such a content transmission example for the purpose of use is merely an example, and an arbitrary transmission method can be set according to the type and content of the content. For example, for a user whose contract with the content transmission device 4 is continuing, the content transmitted for the next month (for example, monthly shogi game) is not transmitted after being packaged for several months. Needless to say, it is transmitted separately every month.

In addition, in the various networks 2 as shown in FIG. 1 (a), there are a large number of communication carriers that communicate information using a unique communication protocol. The call is made through the server of the carrier with which the telephone contract is made. At this time, it is assumed that the content cannot be transmitted to the mobile phone 6 due to a difference in communication protocol.
Therefore, a protocol automatic conversion function is added to the content transmission means 10 (content transmission unit 18) so that the content can be transmitted according to a communication protocol for each communication carrier. As a result, the content can be reliably delivered to the mobile phone 6 without being affected by the difference in communication protocol for each carrier.
