A content distribution system according to an embodiment of the present invention will be described below with reference to the drawings.

  A content distribution system according to a first embodiment of the present invention will be described.

  First, the system configuration of the content distribution system according to the first embodiment of the present invention will be described. FIG. 1 is a block diagram showing the system configuration of the content distribution system of this embodiment. In FIG. 1, the content distribution server 1, the mobile phone 2, and the content server 3 are configured. The content distribution server 1 and the mobile phone 2 are connected using the Internet. The content distribution server 1 and the content server 3 are also connected using the Internet. Of course, each may be connected using a network other than the Internet. In this system, there are Internet service providers and the like for individual users to use the Internet, but the description is omitted because it is not directly related to the present invention.

  The content distribution server 1 is a server for distributing content such as video and music to a communication terminal such as the mobile phone 2. The business operator A who operates the content distribution server 1 earns a monthly basic fee collected from a registered user, a paid content fee charged for each content distribution, and an advertising fee for distributing CM content recruited from other companies. As a source. Of course, you may have other sources of income.

  The mobile phone 2 is a mobile phone having a digital camera function. Internet browsing function, mail sending / receiving function, etc. The content distributed from the content distribution server 1 can be browsed using the Internet browsing function. The digital camera function is not necessarily provided as long as the function of browsing the content is provided. In addition, a terminal such as a digital camera or a PDA that does not have a call function may be used instead of a mobile phone as long as it has a communication function and a content browsing function.

  The content server 3 is a server for providing content to the content distribution server 1. The content server 3 is operated by an operator B different from the operator A that operates the content distribution server 1. Since it is difficult for the business operator A to produce all the contents of many genres to satisfy many users, the content is supplied from the content server 3. The business operator A pays the business user B a content usage fee corresponding to the content distributed from the content server 3 to the user. In the example shown in FIG. 1, one content server is shown, but a plurality of content servers may be used. By receiving content supply from content servers of a plurality of business operators, the types of content can be increased.

  Note that the content produced by other business operators is stored in the content server 3 to suppress the pressure on the memory of the content distribution server 1. Of course, all the content may be stored in the content distribution server 1. Alternatively, all content may be supplied from the content server 3 without storing any content in the content distribution server 1.

  Next, an apparatus constituting the content distribution system in the first embodiment will be described.

  First, the content distribution server 1 in Embodiment 1 is demonstrated.

  FIG. 2 is a block diagram showing the configuration of the content distribution server 1. In FIG. 2, the content distribution server 1 includes a CPU 101, a communication unit 102, a user information database 103, a content database 104, and a program unit 105.

  The CPU 101 is a circuit for managing all the controls executed by the content distribution server 1. The communication unit 102 is a circuit for communicating with external devices such as the mobile phone 2 and the content server 3. The user information database 103 is a database in which user information for using the content distribution service is registered. User information includes information such as authentication ID, password, type of content desired to be delivered such as music and video, favorite genre, etc. registered at the time of user registration at the start of the service, as well as content delivered to the user. The already distributed content list information and the like to be updated are registered.

  The content database 104 stores video content such as moving images and music content. The content database 104 stores management data for managing these contents. The management data includes information that can be searched under conditions such as content genre, content title name, keyword, and content playback time. Further, the management data includes information so that the content stored in the content server 3 that is not stored in the content database 104 can be similarly searched.

  The program unit 105 stores a control program executed by the content distribution server 1. Note that the user information database 103, the content database 104, and the program unit 105 in FIG. 2 are virtually blocked for convenience of explanation, and are actually data stored in a memory device such as a hard disk. is there.

  Next, the mobile phone 2 according to the first embodiment will be described.

  3 and 4 are external views of the mobile phone 2 according to the first embodiment. The mobile phone 2 can be folded in two, and FIG. 3 shows a view of the mobile phone 2 viewed from the inner surface side when the mobile phone 2 is not folded. FIG. 4 shows a view of the cellular phone 2 viewed from the outer surface side in a folded state.

  In FIG. 3, the mobile phone 2 includes a monitor 201, a cursor movement button 202, and a dial button 203. In FIG. 4, the mobile phone 2 includes a sub monitor 204 and an imaging unit 205.

  In addition, among the currently distributed mobile phones, if the mobile phone has an Internet connection function and an application execution function, the content distribution system according to the present embodiment is executed by executing a separately provided content browsing program. It can be used as a mobile phone. Therefore, the internal functions of the mobile phone 2 are already known and will not be described. The content browsing program executed on the mobile phone 2 will be described later. In the present embodiment, the mobile phone 2 having a digital camera function is used as a user terminal. However, a mobile phone without a digital camera function, a PDA, or the like may be used.

  Below, the control performed with the content delivery system by 1st Embodiment is demonstrated.

  First, an outline of control executed in the content distribution system will be described.

  In the content distribution system, the content distribution server 1 searches for content that matches the waiting time of the user, and distributes the content to the user's mobile phone 2.

For example, when a waiting time occurs for a registered user, such as waiting for a train at a station or waiting for a person, the mobile phone 2 is used to connect to the content distribution server 1. When connected to the content distribution server 1, a top page as shown in FIG. 5 is displayed on the monitor 201 of the mobile phone 2. When setting the content to be distributed, if a menu in the top page is selected, the process moves to a subpage shown in FIG. 6 and settings can be made regarding the content to be distributed in addition to the waiting time.

  The waiting time in FIG. 5 can be input directly using the dial button 203. Further, the cursor movement button 202 can be moved to the input field by the left / right operation, and the up / down operation can be performed by the up / down operation of the cursor movement button 202 to set the waiting time.

  The waiting time information is transmitted to the content distribution server 1 by selecting transmission. Content that matches the waiting time is streamed and distributed from the content distribution server 1 to the mobile phone 2.

  Next, content distributed from the content distribution server 1 to the mobile phone 2 will be described.

  The content distributed from the content distribution server 1 to the mobile phone 3 needs to be content that has a playback time that matches the waiting time of the user and that matches the user's preference.

  The content distribution system according to the present embodiment determines content to be distributed in consideration of user registration information registered at the time of user registration in order to provide content that suits the user's preference.

  The user registration information registered in the user registration includes profile information regarding the user such as an authentication ID, a password, a user's age, sex, and family structure. User registration information includes information on whether music content is given priority or video content, genre information on favorite music content, genre information on favorite video content, and length of favorite content (short and long) There is information regarding content such as whether to distribute paid content, presence / absence of audio of video content, audio language, subtitle priority, dubbing priority, and the like. Further, the user registration information is information on the device used such as the model name of the receiving terminal used by the user, the size of the monitor that displays the content, and the communication speed.

  It also has a learning function that automatically updates user registration information, and adds information related to distributed content. This prevents the same content from being distributed twice. In addition, the registration information is updated with information such as cancellation of the distributed content and request for redistribution.

  In addition, the content is evaluated based on statistics such as cancellation status and redistribution status of a plurality of other users who have distributed the content, and the content with favorable evaluation is distributed with priority.

  The content distribution server 1 selects and distributes the content required by the user based on the registered information described above and the waiting time information input immediately before distribution.

  Next, the contents selected by the content distribution server 1 will be described.

  There are paid content distributed free of charge and free content distributed free of charge. There are free contents that aim at the advertising effect of the company as a whole and those that insert the advertisement of the company as part of the content. In addition, there are contents such as paid contents and sample movies for introducing theatrical movies.

  In addition, when the waiting time is long, it is possible to set whether to distribute long-length content or a plurality of short-length content. There is no problem with long-length content in an environment where the content can be viewed at home. However, when the user is out or on the move, it is better to distribute a plurality of short contents in time series even if the waiting time is long in an environment where the contents cannot be viewed carefully. Also, some users may not like content for a long time because their eyes are tired if they are watching the monitor of the mobile terminal for a long time even when they are at home.

  In this way, by controlling so as to distribute the content suitable for the waiting time and the user environment, the waiting time can be used effectively and the end of the waiting time can be notified.

  Next, the control executed in the content distribution system will be specifically described.

  First, content distribution control executed by the content distribution server will be described. FIG. 7 is a flowchart showing the control executed by the content distribution server 1. This flow starts when it is detected that the mobile phone 2 and the content distribution server are communicably connected.

  First, in step S <b> 11, screen information on the top page for allowing the user to input information such as an authentication ID, a password, and a waiting time is transmitted to the mobile phone 2. The top page screen is shown in FIG. Subsequently, in step S12, it is detected whether the input information according to the top page is received from the mobile phone 2. If received, the process proceeds to step S13. If not received, the detection in step S12 is continued.

  In step S13, whether the user is already registered is authenticated from the received authentication ID and password. If user authentication is successful, the process proceeds to step S14. If user authentication is not possible, the process returns to step S11.

  In step S14, information necessary for extracting content from the user registration information of the authenticated user is read out. Subsequently, in step S15, an extraction condition for extracting the optimum content for the user is set based on the read user registration information, the waiting time information received this time, and the like. The database for content search has management data having information such as playback time, genre, appropriate age, appropriate sex, and keyword corresponding to the content. Find the best content. Further, in this database, the contents in the content server 3 are also made into a database.

  Subsequently, in step S16, the content is searched and extracted according to the set extraction condition. Detailed control of content extraction executed in this step will be described later. Next, in step S17, the extracted content is distributed toward the mobile phone 2.

  By controlling in this way, the user can browse the content most suitable for the user and effectively spend it during the waiting time.

  Next, content extraction control for extracting content optimal for the user will be described.

  FIG. 8 is a flowchart showing content extraction control executed by the content distribution server 1. This flow is executed in step S16 of FIG.

  First, in step S31, a search is executed using an extraction condition in which a database for content existing in the content database in the content distribution server 1 is set. Next, in step S32, it is detected whether content matching the extraction condition has been extracted. If extracted, the process proceeds to step S36, and if not extracted, the process proceeds to step S33.

  In step S33, a database for content in the content server 3 is searched. Next, in step S34, it is detected whether the content that matches the extraction condition has been hit. If there is a hit, the process proceeds to step S36; otherwise, the process proceeds to step S35.

  In step S35, the database in the content distribution server 1 and the content server 3 is searched again, and the content closest to the extraction condition is extracted. In step S36, the extracted content is determined as the content to be distributed.

  As described above, in this control, when there is no content that matches the extraction condition, the content that is closest to the extraction condition is automatically extracted, so the user does not need to re-set the extraction condition. , Can receive content that suits the waiting time.

  However, since the waiting time of the user varies, there is a possibility that there is no content having a playback time that completely matches the waiting time. Therefore, it is necessary to process and edit the content so that the playback time of the content matches the waiting time.

  Next, content editing control for processing and editing content will be described.

  In the above embodiment, when there is no content that matches the extraction condition, the content closest to the extraction condition is extracted and distributed to the user's mobile phone 2.

  In the embodiment described below, when there is no content that matches the extraction condition, the content is edited so as to match the extraction condition.

  In content editing, the content is generated using a plurality of contents whose extraction conditions match except for the reproduction time.

  FIG. 9 is a flowchart showing content editing control executed by the content distribution server 1. This flow starts when the content distribution server 1 detects that an authentication signal, waiting time information, position information, or the like has been received from the mobile phone 2.

  First, in step S101, the user registration database is searched based on the authentication signal received from the mobile phone 2. Subsequently, in step S102, it is determined from the search result whether the user has already been registered. If it is a registered user, the process proceeds to step S103, and if it is an unregistered user, the process proceeds to step S111. In step S103, the user information registered in the database is read out. Subsequently, in step S104, information such as waiting time information, time information, and position information received from the user is analyzed.

In step S105, from the registered user information, whether it is video content or audio content, the content genre, the presence or absence of audio, unviewed content, and the received waiting time information, time information, and position information, Set extraction conditions for extracting optimal content. In step S106, the content database is searched with the determined extraction condition. In step S107, it is determined whether there is content that matches the set extraction condition. If there is content that matches the extraction condition, the process proceeds to step S109, and if there is no content that matches the extraction condition. Proceed to step S108.

  In step S108, content creation processing is performed to generate content that meets the set extraction conditions. The content creation process here will be described later. In step S109, the content is processed in accordance with the reception environment of the user terminal, here, in accordance with the reception environment of the mobile phone 2. In the content processing here, the image size and the bit rate are increased or decreased in accordance with the communication speed of the user terminal, the screen size, and the like. In step S110, the content is distributed to the user terminal.

  On the other hand, in step S111, a page describing the failure of authentication and prompting user registration is transmitted to the mobile phone 2. Subsequently, in step 112, it is detected whether a signal indicating user registration is received from the mobile phone 2. If detected, the process proceeds to step 113, and if not detected, the process proceeds to step 114. In step 113, user registration work is executed. In step 114, it is detected whether a signal such as authentication information has been received from the mobile phone 2 again. If it is detected, the process returns to step 101. If not, the flow ends.

  As described above, when content that matches the extraction condition is not found, it is possible to distribute the optimum content to the user by generating content that matches the extraction condition.

  Next, the content creation process executed in step S108 of FIG. 9 will be specifically described. If there is no content that matches the set extraction condition, the following processing is executed.

  (1) A plurality of contents having playback times shorter than the waiting time are connected to match the playing time with the waiting time. Alternatively, a plurality of contents are continuously distributed in time series. (2) A process of extending the playback time of content whose playback time is slightly shorter than the waiting time is made to coincide with the waiting time. (3) A measure for shortening the playback time of the content having a playback time slightly longer than the waiting time is made to coincide with the waiting time. (4) CM video content is inserted into content whose playback time is slightly shorter than the waiting time so as to match the waiting time. (5) Divide content having a longer reproduction time than the waiting time into a plurality of times according to the waiting time, and divide the distribution into a plurality of times.

  Hereinafter, specific content creation control executed by the content distribution server will be described.

  First, processing for connecting a plurality of contents that meet conditions other than time will be described. Here, an example of connecting two contents is introduced.

  FIG. 10 is a flowchart showing an example of content generation control executed in step S108 of FIG.

  First, in step S201, the playback time does not match the waiting time, and other conditions are extracted for content that meets the extraction conditions. Subsequently, in step S202, it is determined from the user information whether the user desires short content. If short content is desired, the process proceeds to step S203. If short content is not desired, the process proceeds to step S204. move on.

In step S203, a short content having a reproduction time of a predetermined time or less is extracted from the content extracted in step S201. In step S204, long content and short content having a reproduction time equal to or longer than a predetermined time close to the waiting time are extracted from the content extracted in step S201.

  In step S205, a combination in which the total reproduction time when the extracted plurality of contents are connected in time series matches the waiting time is extracted. In step S206, an optimum combination is selected from the extracted combinations. Next, in step S207, a plurality of contents corresponding to the extracted combination are read out and edited so as to be reproduced continuously in time series.

  By controlling in this way, even if the playback time of one content does not match the waiting time, the content having the playback time matching the waiting time is distributed to the user by connecting a plurality of contents. be able to.

  Next, an example of extending the playback time of one or more contents whose playback time is shorter than the waiting time will be described.

  For example, if the user has a waiting time of 31 minutes and content with a playback time of 30 minutes exists, the content is processed so that the 30 minutes of content is played back slowly in 31 minutes. However, it is implemented only for content that the content copyright holder has permitted such a content reproduction method.

  FIG. 11 is a flowchart showing an example of content generation control executed in step S108 of FIG.

  First, in step S301, the contents in the database are searched, and contents satisfying the extraction conditions for other conditions are extracted in a time shorter than the waiting time. In step S302, the content closest to the waiting time is selected. In step S303, the distribution speed is calculated based on the playback time and waiting time of the selected content. In step S304, the selected content is treated so as to be played slowly at the calculated speed. In step S305, a character string indicating that the playback speed of the content is slower than usual is treated so as to overlap the content video. FIG. 12 shows a display example.

  By controlling in this way, it is possible to make the content reproduction time coincide with the waiting time. In addition, it is possible to distribute the optimum content to the user by using the content that satisfies the conditions other than the playback time, instead of using the content whose playback time is closest to the waiting time.

  Next, an example in which the playback time of content having a playback time longer than the waiting time is shortened will be described. For example, if the user has a waiting time of 29 minutes and there is content with a playback time of 30 minutes, the content is processed so that the 30 minutes of content is quickly played back in 29 minutes. Similar to the slow playback of the content described above, some copyright holders may not allow such changes unless they fit the work intent. This is only done for content that the copyright holder allows for such usage.

  FIG. 13 is a flowchart showing an example of content generation control executed in step S108 of FIG.

First, in step S401, the database is searched, and contents meeting other conditions are extracted in a time longer than the waiting time. In step S402, the content closest to the waiting time is selected. In step S403, the distribution speed is calculated based on the playback time and waiting time of the selected content. In step S404, the selected content is treated so that quick playback is performed at the calculated speed. In step S405, a character string indicating that the playback speed of the content is faster than normal is displayed so as to overlap the content video. FIG. 12 shows a display example.

  Further, even if there is content that matches the waiting time, the above control may be used for a user who wants to view a lot of content in a short time. For example, a news content having a playback time twice as long as the waiting time can be played back at a double speed to shorten the viewing time.

  Next, the time is adjusted by adding short-time content such as CM to the content.

  The CM content is distributed upon receiving a request from another company. CM content is distributed only to users who meet age, sex, and other conditions determined by the company. The provider of the content distribution server 1 collects a fee from the company that requested the user by distributing CM content to the user. In the content distribution server 1, CM contents having various reproduction times are prepared as reproduction time adjustment contents.

  FIG. 14 is a flowchart showing an example of content generation control executed in step S108 of FIG.

  First, in step S501, the contents in the database are searched, and contents satisfying the extraction conditions for other conditions are extracted in a time shorter than the waiting time. Subsequently, in step S502, the content closest to the waiting time is selected. Next, in step S503, the time difference between the playback time and waiting time of the selected content is calculated. Next, in step S504, CM content with the calculated playback time difference is extracted. In step S505, processing is performed so that the content selected in step S502 and the CM content are continuously reproduced. The CM content can be selected to which part of the selected content is connected. For example, it is possible to select whether to reproduce the CM content before, during, or after the selected content. When an incoming call or a call is made during content viewing, the content playback is interrupted, so there is a possibility that the CM content need not be played back during the waiting time, so the CM content is played back last as an initial value. Treated as follows.

  By controlling in this way, it is possible to make the content reproduction time coincide with the waiting time. Further, the content in the content server 3 is basically paid content in order to pay a content usage fee to a business operator operating the content server 3. By distributing the paid content in combination with the paid content, the fee burden on the user is reduced by offsetting the paid content fee with the charged CM content fee.

  Next, content distribution control for users who wish to distribute paid content will be described. The user who wants to distribute paid content is also charged. It is inconvenient for the user to be charged for content that he does not want to watch. The content server 1 can also check the degree of popularity of the content to be distributed.

  FIG. 15 is a flowchart showing content distribution control executed by the content distribution server 1. This flow starts by detecting that a signal has been received from the mobile phone 2.

First, in step S1001, it is determined from the user registration information whether the user desires paid distribution. If so, the process proceeds to step S1002, and if not, the process proceeds to step S1010. In step S1002, paid content that matches the extraction condition is extracted. Next, in step S1003, the extracted paid content is distributed toward the user terminal. Subsequently, in step S1004, the character string information is transmitted so that the character string inquiring whether to accept the charge is displayed overlapping the content video. Next, in step S1005, it is detected whether a signal for approving charging is received from the user terminal. If detected, the process proceeds to step S1006, and if not detected, the process proceeds to step S1008.

  In step S1006, billing processing is executed. In step S1007, transmission of character string information is stopped.

  In step S1008, it is detected whether a signal that does not approve charging has been received. If detected, the process proceeds to step S1010. If not detected, the process proceeds to step S1009. In step S1009, it is determined whether a predetermined time has elapsed since the content began to be distributed. If the predetermined time has elapsed, the process proceeds to step S1010. If the predetermined time has not elapsed, the process returns to step S1004.

  In step S1010, distribution of paid content and character string information is stopped. Subsequently, in step S1011, free content that matches the extraction condition is extracted. Here, content is extracted in consideration of the elapsed time from the waiting time input. Next, in step S1012, the extracted free content is distributed to the user terminal.

  By controlling in this way, the charging is confirmed by overlapping with the content distribution, so the distribution of the paid content does not go wrong with the waiting time for the charging confirmation. In addition, when consent to charge for paid content is not obtained, the free content is automatically redistributed, so that the distribution procedure is not performed again. In addition, when consent to charge for paid content is not obtained, the content to be distributed is searched from the free content in consideration of the elapsed time, so the waiting time does not go wrong.

  Next, a content distribution system according to another embodiment will be described. In the embodiment described below, the content distribution server 1 does not determine the content to be distributed unilaterally, but distributes content information list information that meets the extraction conditions, and allows the user to select a favorite content. is there.

  For example, when a waiting time of 15 minutes occurs, the user transmits waiting time information indicating that the waiting time is 15 minutes to the content distribution server 1 using the mobile phone 2. Then, a list of content titles with a playback time of 15 minutes is transmitted from the content distribution server 1. In the content title list, the content information is arranged in the order of user preference determined from the user registration information. FIG. 16 shows a display example of the content title list. By designating a content title that the user wants to see from the content title list, the content is distributed from the content distribution server 1 to the mobile phone 2.

  Specific control will be described below.

  First, the control executed by the content distribution server 1 will be described. FIG. 17 is a flowchart showing the control executed by the content distribution server 1. This flow starts by detecting that a signal has been received from the mobile phone 2.

First, in step S1101, content extraction conditions are set according to waiting time information and user registration information received from the user. Next, in step S1102, the content is searched with the set extraction condition. In step S1103, the contents extracted in the order of user preference determined from the user registration information are ranked.

  In step S1104, content title list information in which content titles are arranged in the user's preference order is generated and transmitted to the mobile phone 2. In step S1105, it is detected whether content instruction information is received from the mobile phone 2. If received, the process proceeds to step S1106. If not received, the detection in step S1105 is continued.

  In step S1106, the instructed content is read from the content database, and if necessary, processed and edited into content suitable for the reception and display environment of the user's mobile phone 2. Subsequently, in step S1107, the content is transmitted to the mobile phone 2.

  Next, control executed in the mobile phone 2 will be described.

  FIG. 18 is a flowchart showing the control executed by the mobile phone 2. This flow starts upon detection of reception of a signal from the content distribution server 1.

  First, in step S1201, the top page received from the content distribution server 1 is displayed on the monitor 201. Next, in step S1202, waiting time information or the like is input in accordance with a page instruction, and it is detected whether a transmission operation has been performed. If an operation is detected, the process proceeds to step S1203. If an operation is not detected, the detection is continued in step S1202.

  In step S1203, the input information is transmitted to the content distribution server 1. In step S1204, it is detected whether content title list information is received from the content distribution server 1. If the content title list information is received, the process proceeds to step S1205. If the content title list information is not received, the detection is continued in step S1204.

  In step S1205, a list of content titles is displayed on the monitor 201 in accordance with the received content title list information. In step S1206, it is detected whether a content title is selected and a transmission operation is performed. If a transmission operation is detected, the process proceeds to step S1207. If a transmission operation is not detected, the detection is continued in step S1206.

  In step S1207, the content instruction information is transmitted to the content distribution server 1. In step S1208, it is detected whether the content of the instructed content title has been received. If reception is detected, the process proceeds to step S1209. If reception is not detected, detection is continued in step S1208. In step S1209, the content reproduction program is activated to reproduce the received content and display it on the monitor 201.

  As described above, when there are a plurality of contents that match the extraction condition, the contents to be distributed are selected by the user, so that it is possible to prevent the contents that are not desired to be distributed from being distributed.

  Next, change control for changing content being distributed to another content will be described.

Even if content is selected according to the user's favorite genre, there is content that is not appropriate depending on the time and place. For example, if you are viewing a comedy content while traveling on a train with other passengers, it may spurt out and inconvenience other passengers.

  In such a case, the user operates the genre change button. The mobile phone 2 assigns an existing button to the genre change button only during content distribution. For example, the numeric keypad “0” is assigned to the genre change button. When the genre change button is operated, the content is switched to a genre (second priority genre) different from the genre of the content being distributed and redistributed. The second priority genre information is registered in advance in the user registration information. When the content change button is operated, if there is content different in the same genre as the content being distributed, the content is switched to a different content in the same genre and redistributed. Similar to the genre change button, the mobile phone 2 assigns an existing button to the content change button only during content distribution. For example, the numeric keypad “9” is assigned to the content change button. If there is no different content in the same genre, the content may be redistributed by switching from the second priority genre to the content.

  FIG. 19 is a flowchart showing content change control executed by the content distribution server 1. This flow is executed simultaneously with content distribution.

  First, in step S2001, it is detected whether or not the genre change button has been operated. If an operation is detected, the process proceeds to step S2002, and if not detected, the process proceeds to step S2004. In step S2002, the content distribution being distributed is stopped. Subsequently, in step S2003, the content database is searched again in order to extract the content of the second priority genre with the remaining waiting time.

  In step S2004, it is detected whether or not the content change button has been operated. If an operation is detected, the process proceeds to step S2005, and if not detected, the process proceeds to step S2008. In step S2005, the content distribution being distributed is stopped. Subsequently, in step S2006, the content database is searched again in order to extract different contents of the same genre with the remaining waiting time.

  In step S2007, the newly extracted content is distributed. Next, in step S2008, it is detected whether content is being distributed. If the distribution is in progress, the process returns to step S2001, and if the distribution has been completed, the flow ends.

  By controlling as described above, it is possible to easily change from the content being delivered to a different content, and the content that automatically matches the remaining waiting time from the time of change is automatically delivered, so the user again waits for the waiting time There is no need to enter.

  Note that the system according to the first embodiment of the present invention can be realized by a mobile phone that does not have a digital camera function as long as the mobile phone has an Internet browsing function. In addition, a terminal having an Internet browsing function can be realized without using a mobile phone.

  Another embodiment will be described.

  Next, a content distribution system in cooperation with home appliances such as a microwave oven will be described. FIG. 20 is a diagram illustrating a home appliance network constituting the content distribution system.

20, the content distribution system in the home appliance network of the present embodiment includes a content distribution server 1, a mobile phone 2, a home server 4, a microwave oven 5, a television 6, an audio player 7, a video 8, a washing machine 9, a refrigerator 10, It consists of a digital camera 11 and a vacuum cleaner 12.

  The content distribution server 1 and the mobile phone 2 have the same functions as those described in the above embodiment. The home server 4 can control home appliances connected to the network. In addition, a large-capacity memory such as a hard disk is provided to store contents. In addition, by connecting to the content distribution server 1 and mediating between the content distribution server 1 and the home appliance, it is possible to view the optimum content for the waiting time of the user who uses the home appliance.

  This embodiment demonstrates the content delivery system using the microwave oven 5 in a household appliance.

  FIG. 21 is a diagram illustrating an appearance of the microwave oven 5. In FIG. 21, the microwave oven 5 includes a monitor 503, a cooking start button 510, a cross button 511, and a cooking method setting button 512.

  FIG. 22 is a block diagram for explaining the function of the microwave oven 5. In FIG. 22, the microwave oven 5 includes a CPU 501, a display control circuit 502, a monitor 503, a memory 504, a switch circuit 505, a cooking unit 506, and a communication circuit 507.

  The CPU 501 is a circuit that controls all functions executed in the microwave oven 5. The display control circuit 502 is a circuit that controls an image displayed on the monitor 503. The memory 504 stores a control program for realizing functions executed in the microwave oven 5. In addition, the content distributed from the content distribution server 1 is temporarily stored. The switch circuit 505 is a circuit that detects that the cooking start button 510, the cross button 511, and the cooking method setting button 512 are operated. The cooking circuit 506 is a circuit for realizing cooking in the microwave oven 5. The communication circuit 507 is a circuit for communicating with the content distribution server 1 via the home server 4.

  Next, control executed in the content distribution system of this embodiment will be described.

  When the cooking time in the microwave oven 5 is determined, the content to be viewed in the waiting time is distributed as a waiting time. The content distribution destination may be a terminal having a large monitor or a microwave oven terminal. Change the distribution terminal according to the cooking time. For example, when the cooking time is 1 hour, if the content is distributed to the microwave oven 5, the content is browsed for 1 hour in the kitchen with the microwave oven 5. On the other hand, if it is distributed to a large monitor terminal such as the television 6 placed in the living room, it can be browsed in a living room with an excellent browsing environment. When the cooking time is 1 minute, it is troublesome to return to the kitchen when browsing in the living room after leaving the kitchen. Also, the terminal can be switched during distribution. The delivery destination can be switched so that the content delivered to the microwave oven 5 is delivered to the television 6 from the middle. As a switching method, a switching mode is selected and a terminal for switching distribution is selected.

  First, the control executed on the microwave oven 5 side will be described.

  FIG. 23 is a flowchart showing cooking control executed in the microwave oven 5. This flow starts when it is detected that the cooking method setting button 512 is operated by the user.

First, in step S3001, the amount of cooking ingredients and the time required for cooking are calculated based on the recipe and displayed on the monitor 503. In step S3002, content extraction conditions are set from the cooking time and user information. In step S3003, an instruction is given to search for content in the content distribution server 1 via the home server 4 under the extraction condition. Next, in step S3004, the optimum content is selected from the user information and the like from the content extracted by searching.

  Subsequently, in step S3005, content instruction information for instructing distribution of the selected content is transmitted to the content distribution server 1, and download is executed. Next, in step S3006, it is detected whether the cooking start button 510 has been operated. If an operation is detected, the process proceeds to step S3007. If an operation is not detected, the operation detection is continued.

  In step S3007, cooking is started. In step S3008, the downloaded content is played back and displayed on the monitor 503. Next, in step S3009, it is detected whether cooking time has passed. If it is finished, the process proceeds to step S3010. If it is not finished, cooking is continued.

  In step S3010, a process for ending cooking is executed. In step S3011, the monitor 503 displays that cooking and content reproduction have been completed.

  Next, control executed on the content distribution server 1 side will be described. The content distribution server 1 executes control for distributing the content designated by the microwave oven 5.

  FIG. 24 is a flowchart showing content distribution control executed by the content distribution server 1. This flow starts when it detects that it is connected to the microwave oven 5 side.

  First, in step S3101, content information can be searched for the microwave oven 5 side. Next, in step S3102, it is detected whether content instruction information has been received from the microwave oven 5 side. If received, the process proceeds to step S3103. If not received, the detection is continued. In step S3103, the designated content is extracted. Subsequently, in step S3104, the extracted content is distributed to the microwave oven side.

  By controlling as described above, content having a playback time that matches the cooking time by the microwave oven is distributed, so that the user can watch the content during the cooking time and know the end of cooking.

  In the above control, an example is shown in which content is downloaded before cooking is started. Downloading may be started at the same time cooking is started.

  In the embodiment to be described next, an example is shown in which content selection or the like is not performed on the microwave oven 5 side, user information or the like is analyzed on the content distribution server 1 side, optimal content is selected, and distribution is executed.

  The microwave automatically determines the cooking time based on the amount of cooking ingredients and the recipe. In some cases, the user manually inputs the cooking time.

  First, control executed in the microwave oven 5 will be described.

  FIG. 25 is a flowchart showing content reproduction control executed in the microwave oven 5. This flow starts when an operation of the cooking start button 510 is detected.

  First, in step S3501, information including the cooking time is transmitted to the content distribution server 1 via the home server 4. The information including the cooking time includes information such as the IP address, model information, authentication ID, and password of the microwave oven 5. Next, in step S3502, cooking is started. In step S3503, the content received from the content distribution server 1 is reproduced and displayed on the monitor 503.

  Next, in step S3504, it is detected whether the cooking time has elapsed. If the cooking time has elapsed, the process proceeds to step S3505, and if not, detection continues.

  In step S3505, cooking ends. In step S3506, the monitor 503 displays that cooking and content reproduction have been completed.

  Next, control executed by the content distribution server 1 will be described.

  FIG. 26 is a flowchart showing content distribution control executed by the content distribution server 1. This flow starts by detecting that a connection is established with the microwave oven 5 side.

  First, in step S3601, information is received from the microwave oven 5 side. The received information includes information such as cooking time information, an IP address of the microwave oven 5, model information, an authentication ID, and a password. Subsequently, in step S3602, the information received from the microwave oven 5 side is analyzed. Next, in step S3603, an extraction condition for extracting optimum content is set. Next, in step S3604, content is searched and extracted under the set extraction condition. In step S3605, an optimum content is selected from the extracted content. In step S3606, the selected content is distributed to the microwave oven 5 side.

  In the above control, the embodiment in which the cooking time is automatically set by the microwave oven 5 has been described. However, the present invention can also be applied to a microwave oven in which the user inputs and sets the cooking time.

  Moreover, although embodiment which receives a content from a content delivery server was demonstrated, you may use the content memorize | stored in the memory in the microwave oven 5, or the home server 4 connected to the home network.

  Another embodiment will be described.

  In the following embodiment, an example will be described in which content is displayed on another device connected to the microwave oven 5 and the network, for example, the television 6.

  For example, in the case of the microwave oven 5 having an oven function, cooking time using the oven may be as long as 1 hour. In order to keep watching the content in front of the monitor provided in the microwave oven 5 installed in the kitchen during a long cooking time, the environment for viewing is not good. I want to watch in an environment that can withstand long-time viewing of the TV 6 etc. installed in the living room.

  The television 6 and the microwave oven 5 are connected via a home server 4 via a network and are controlled by the home server 4. The home server 4 is connected to the content distribution server, receives the content, and controls so that the content can be played back on the television 6 or the microwave oven 5.

  When viewing the content on the television 6, the user sets the ingredients in the microwave oven 5 to be ready for cooking, and then selects the television 6 as a device for reproducing the content. FIG. 27 is a diagram illustrating a setting screen displayed on the monitor 503 of the microwave oven 5. The television 6 is selected instead of the microwave oven 5 in the display device in the figure. Then, the user goes to the television 6 to view the content, and instructs the start of cooking of the microwave oven 5 from the menu automatically displayed on the television monitor. Then, cooking of the microwave oven 5 is started through the network, and content is reproduced on the television monitor. When the content reproduction on the TV monitor is finished, cooking by the microwave oven 5 is also finished.

  FIG. 28 is a flowchart showing the control executed by the home server 4. This flow starts when it detects that the microwave oven 5 has been operated.

  First, in step S3701, information is acquired from the microwave oven 5. Subsequently, in step S3702, an extraction condition for extracting content from information acquired from the microwave oven 5 and user information registered in advance is set. In step S3703, the content distribution server 1 is connected.

  Subsequently, in step S3704, according to the extraction condition, the content having the optimum reproduction time corresponding to the cooking time is extracted from the content stored in the content distribution server 1.

  In step S3705, it is detected from the acquired information whether the content reproduction device is set to the microwave oven 5 or the television 6. If the microwave oven 5 is selected, the process proceeds to step S3706, and if the television 6 is selected, the process proceeds to step S3707. In step S3706, normal control for reproduction by the microwave oven 5 is executed.

  On the other hand, in step S3707, it is detected whether the power of the television 6 is turned on. If it is turned on, the process proceeds to step S3709. If it is not turned on, the process proceeds to step S3708. In step S3708, the TV 6 is turned on. In step S3709, a microwave operation menu is displayed on the television monitor. FIG. 29 is a diagram illustrating an example of a microwave operation menu.

  Next, in step S3710, it is detected whether a cooking start operation has been performed. If it is operated, the process proceeds to step S3711. If it is not operated, the operation detection is continued. In step S3711, the microwave oven 5 is instructed to start cooking. Subsequently, in step S3712, the content distribution server 1 is instructed to distribute the extracted content. In step S3713, an instruction to reproduce the content distributed to the television 6 is given.

  Next, in step S3714, it is detected whether the cooking time has elapsed. If it has elapsed, the process proceeds to step S3715. If it has not elapsed, progress detection is continued. In step S3715, the connection with the content distribution server is disconnected.

  In step S3716, it is confirmed whether cooking by the microwave oven 5 has been completed. If it has been completed, the process advances to step S3718; otherwise, the process advances to step S3717. In step S3717, a warning is displayed on the television monitor. Next, in step S3718, a menu screen for performing an operation such as power-off is displayed on the television monitor.

  As described above, in the content viewing system according to the present embodiment, the content can be viewed on other devices such as a television set in the living room, so that the content can be viewed without difficulty even if the cooking time is long. Can also inform you that cooking has ended.

  In the microwave oven 5, not only the television 6 but also an audio player 7 connected to the home network can be selected as a content appreciation device. If the content to be distributed is not video content but music content, it is possible to select and view the audio player 7 instead of the television.

  Next, still another embodiment will be described.

  Although it came in front of the microwave oven 5 in order to confirm whether cooking was complete | finished, cooking may not be complete | finished and it may wait in front of the microwave oven 5 for the last several minutes until completion | finish of cooking. By operating the microwave oven 5 at that time, it is possible to enjoy the content and spend the remaining time. In this case, the content is displayed on the monitor 503 provided in the microwave oven 5.

  In the present embodiment, an example in which content stored in the home server 4 instead of the content distribution server 1 is viewed is shown. In the home server 4, content recorded by the user such as broadcast programs is stored.

  FIG. 30 is a flowchart showing the control executed in the microwave oven 5. This flow starts when it is detected that the user has operated to view the content during cooking.

  First, in step S4001, the remaining cooking time is detected. In step S4002, the home server 4 is accessed to search for content recorded in the home server 4. Next, in step S4003, content having a reproduction time optimum for the detected remaining cooking time is extracted. In step S4004, the home server 4 is instructed to distribute the extracted content.

  In step S4005, the distributed content is played back and displayed on the monitor 503. Next, in step S4006, it is detected whether the cooking time has elapsed. If it has elapsed, the process proceeds to step S4007. If it has not elapsed, the detection is continued.

  In step S4007, cooking ends. Subsequently, in step S4008, the content reproduction is terminated, and a display indicating the end of cooking is displayed on the monitor 503.

  By controlling as described above, a user who has come to the kitchen to confirm whether cooking has been completed can appreciate contents up to the end of the cooking time when cooking has not been completed. As a result, the user does not waste the waiting time.

  In the above embodiment, content having the same playback time as the remaining cooking time is selected. However, content with a playback time longer than the cooking time may be selected, and playback of the content may be interrupted when cooking ends. The content reproduction interruption informs the user of the end of cooking. Also, it is possible to reproduce the content that the user wants to see. In addition, the content that has been viewed halfway may be played back continuously. This will be described below.

  An example of control by the home server 4 will be described. FIG. 31 is a flowchart showing content distribution control executed by the home server 4. This flow starts by receiving cooking time information from the microwave oven 5.

  First, in step S5001, it is detected whether there is content having interruption location information where distribution or reproduction is interrupted among the content recorded in the memory in the home server 4. If there is content having interruption location information, the process proceeds to step S5002, and if there is no content having interruption location information, the process advances to step S5003. In step S5002, the content interrupted immediately before is extracted from the content having the interruption location information so as to be reproduced from the interruption location. In step S5003, the content recorded immediately before in the memory is extracted. Next, in step S5004, it is detected whether a cooking start signal has been received from the microwave oven 5. If received, the process proceeds to step S5005. If not received, the detection is continued.

  In step S5005, the extracted content is distributed to the microwave oven 5. Next, in step S5006, it is detected whether a cooking end signal has been received from the microwave oven 5. If received, the process proceeds to step S5007. If not received, the detection is continued.

  In step S5007, it is detected whether the content distribution has been completed. If it has been completed, this flow ends. If it has not ended, the flow advances to step S5008. In step S5008, the distribution of the content to the microwave oven 5 is stopped. Subsequently, in step S5009, the interrupted part information indicating the part where the distribution is interrupted is stored in association with the content in association with the distributed content information. By storing the interruption location information, it is possible to deliver from the location where it was interrupted the next time it is delivered to another device. Further, even when the home server 4 itself reproduces the content, it can be reproduced from the interruption location based on the interruption location information.

  By controlling as described above, even when the cooking time and the content reproduction time do not coincide with each other, the user can appreciate the content that the user wants to appreciate and can know the end of the cooking time.

  Since the content is reproduced from the middle or when the interruption is interrupted, the interruption location information is recorded. This is particularly effective when the content is recorded in a memory such as the home server 4 that can be personally managed.

  In the embodiment described above, an example in which the microwave oven 5 is used as a representative home appliance has been described, but the present invention can also be realized with the other home appliances illustrated in FIG. Corresponding to cooking time by microwave oven 5, washing time by washing machine, drying time, cleaning time by automatic cleaner, thawing time by refrigerator, ice making time, charging time for mobile phone, digital camera, etc., dubbing of audio player Time, video tape rewind, fast forward time, recording time, etc.

  The digital camera 11 according to the embodiment described below uses data stored in a memory card in the digital camera 11 as content, and enables browsing of content that matches the waiting time. The data stored in the memory card includes still image data, moving image data, content data downloaded from others, and the like. If the digital camera 11 includes a television tuner, the recorded broadcast program data can be used as content.

  Hereinafter, a method of using data in the digital camera 11 as content will be described.

  A slide show function for reproducing still image data captured by the digital camera 11 in a predetermined order is used. In accordance with the input waiting time, the number of still images to be played back in the slide show and the playback time per still image are set.

  The moving image data photographed by the digital camera 11 is continuously reproduced in accordance with the input waiting time. In addition, content combining still image data, moving image data, and broadcast program data may be generated and reproduced.

  Hereinafter, control using the slide show function for reproducing still image data stored in the memory in the digital camera 11 during a waiting time will be described.

  FIG. 32 is a flowchart showing the slide show control executed by the digital camera 11. This flow starts when a slide show is selected in the waiting time mode.

  First, in step S6001, it is detected whether a waiting time is input. If a waiting time input is detected, the process proceeds to step S6002, and if a waiting time input is not detected, the input detection is continued. In step S6002, the optimum number of still image data to be reproduced and the reproduction time are calculated according to the input waiting time. Subsequently, in step S6003, the memory card is checked to see if the calculated number of image data exists. When it exists, it progresses to step S6005, and when it does not exist, it progresses to step S6004.

  In step S6004, the reproduction time is recalculated from the number of image data existing in the memory card. In step S6005, the slide show function is set so that the slide show is executed with the calculated number or the existing number and the reproduction time. In step S6006, the set slide show is executed.

  By controlling as described above, the number of images to be reproduced is automatically set according to the waiting time, or the reproduction time of one image is automatically set, so that the waiting time can be easily set. A slide show with a combined playback time can be executed.

  In addition to automatically setting the number of images and the reproduction time of the images, the user can set either the number of images or the reproduction time.

  Also, the playback time may be automatically set by the number of sheets using the time already set in the normal slide show setting.

  In the following, an example in which the playback time is already set will be described.

  FIG. 33 is a flowchart showing the slide show control executed by the digital camera 11. This flow starts when a slide show is selected in the waiting time mode.

  First, in step S6101, it is detected whether a waiting time has been input. If a wait time input is detected, the process proceeds to step S6102, and if a wait time input is not detected, the input detection is continued. In step S6102, the reproduction time information of one image set in the normal slide show setting is read.

  In step S6103, the number of still image data to be reproduced is calculated according to the input waiting time and the set reproduction time. In step S6104, the memory card is checked to determine whether there is the calculated number of image data. When it exists, it progresses to step S6106, and when it does not exist, it progresses to step S6105.

  In step S6105, the playback time is calculated from the number of image data present in the memory card. In step S6106, the slide show function is set so that the slide show is executed with the calculated number or the existing number and the reproduction time. In step S6107, the set slide show is executed.

  By controlling as described above, since the reproduction time information per frame already set in the normal slide show is used, it is possible to execute the slide show according to the waiting time with the reproduction time desired by the user.

  Further, when only the playback time is determined as in a conventional slide show, the end time cannot be determined by the number of image data. The end time can be known by adjusting the number of playbacks or the playback time.

  In the embodiment described below, image data to be deleted can be selected during a slide show. When viewing a slideshow, you may find that you don't need an image and want to delete it. While watching a slide show, if an image to be deleted was found, it was necessary to go out of the slide show and set it in a deleteable mode to find the image to be deleted.

  In the present embodiment, it is possible to select image data to be deleted even when a slide show is being executed, and to easily instruct deletion. In addition to the deletion instruction, instructions such as the presence / absence of printing, the number of prints, and the presence / absence of external transfer can be performed on the image data during the slide show.

  Hereinafter, image data selection control during the slide show will be described.

  The image data selected by the above control can be targeted for deletion, printing, external transfer, and the like.

  FIG. 34 is a flowchart showing the slide show control executed by the digital camera 11. This flow starts when a slide show is executed.

  First, in step S7001, image data to be reproduced in the set reproduction order is selected. In step S7002, the image data in the selected memory card is read and displayed on the monitor. In step S7003, it is detected whether a selection operation has been performed. If a selection operation is detected, the process proceeds to step S7004, and if not, the process proceeds to step S7005.

  In step S7004, selection information indicating selection is stored in the memory card in association with the image data being reproduced. In step S7005, it is detected whether the set playback time has elapsed. If the set playback time has elapsed, the process proceeds to step S7006. If not, the process returns to step S7003.

  In step S7006, it is detected whether image data to be reproduced next exists. When it exists, it progresses to step S7007, and when it does not exist, it progresses to step S7008. In step S7007, image data to be reproduced next is selected in the set reproduction order, and the process returns to step S7002. In step S7008, the reproduction of the image data by the slide show is ended.

  In step S7009, it is detected whether there is image data selected and operated during the slide show executed this time. If it exists, the process proceeds to step S7010. If it does not exist, this flow ends. In step S7010, a menu for selecting how to process the image data selected during the slide show is displayed on the monitor. In step S7011, it is detected whether an instruction has been given to the menu. If the instruction is detected, the process proceeds to step S7012, and if the instruction is not detected, the detection is continued.

  In step S7012, the process instructed by the menu is performed on the image data.

  By controlling as described above, it is possible to select image data to be subjected to processing such as image data deletion without interrupting the slide show.

  In the above control, image data can be selected without interrupting the slide show. However, if the operation for instructing selection is delayed, there is a possibility that image data different from the image that the user wanted to select has been selected. In the above control, the process for the selected image data is selected from the menu after the slide show.

  The digital camera 11 according to the embodiment described below includes a function that can definitely select selected image data when a slide show is executed.

  A selection operation during the slide show execution of the present embodiment will be described. Control for selecting image data to be deleted will be described.

  FIG. 35 is a flowchart showing the slide show control executed by the digital camera 11. This flow starts when a slide show is executed.

  First, in step S7101, image data to be reproduced is selected in the set reproduction order. In step S7102, image data in the selected memory card is read and displayed on the monitor. In step S7103, it is detected whether a deletion operation has been performed. If a deletion operation is detected, the process proceeds to step S7104. If not detected, the process proceeds to step S7108.

  In step S7104, the slide show is interrupted. Subsequently, in step S7105, the image reproduced when the deletion operation is detected and the image data reproduced immediately before are displayed side by side on the monitor. A menu for instructing which of the two images to select is displayed. The reason why the two images are displayed side by side is that, if the deletion operation is delayed, there is a possibility that the image next to the image to be deleted has already been reproduced at the time of the operation.

  Next, in step S7106, it is detected whether one or both of the two images are instructed to be selected. If a selection instruction is given, the process proceeds to step S7107. If a selection instruction is not given, detection of the instruction is continued. In step S7107, selection information indicating that deletion has been selected in association with image data selected for deletion is stored in the memory card. In step S7108, the process returns to the slide show.

In step S7109, it is detected whether the set playback time has elapsed. If the set playback time has elapsed, the process proceeds to step S7110; otherwise, the process returns to step S7103.

  In step S7110, it is detected whether image data to be reproduced next exists. If it exists, the process proceeds to step S7111, and if it does not exist, the process proceeds to step S7112. In step S7111, image data to be reproduced next is selected in the set reproduction order, and the process returns to step S7102. In step S7112, the reproduction of the image data by the slide show is ended.

  Subsequently, in step S7113, it is detected whether there is image data selected and operated during the slide show executed this time. If it exists, the process proceeds to step S7114, and if it does not exist, this flow ends.

  In step S7114, a slide show for sequentially reproducing the image data that has been deleted during the slide show is executed. As a result, the image data to be deleted can be confirmed again.

  In step S 7115, it is detected whether a deletion confirmation operation has been performed. If detected, the process proceeds to step S7116. If not detected, the detection is continued. Next, in step S7116, it is detected whether the slide show has ended. If it has been completed, the process advances to step S7118; otherwise, the process advances to step S7117.

  In step S7117, the slide show is interrupted. When the deletion confirmation operation is performed, it is considered that it is confirmed that the image data reproduced in the slide show after that can be deleted. In step S7118, the deletion-instructed image data is deleted.

  With the above control, it is possible to reliably instruct image data to be processed during the slide show. In addition, since the slide show for reproducing the image data to be processed starts after the slide show ends, the image to be processed can be easily confirmed.

  In the above control, the image data is not deleted at the time of deletion selection, but is deleted after the confirmation again. However, the image data may be deleted at the time of deletion selection.

  Further, even if the delete button is operated during the slide show, the user can select to delete without interrupting the slide show without confirming the image to be deleted.

In that case, it is desirable to delete after confirming the deletion selection image after the slide show.
