Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(Embodiment 1)
FIG. 1 shows an embodiment of a recorded content viewing system disclosed in the section for solving the problems.

  In FIG. 1, a recorded content viewing system includes a personal computer 210 corresponding to a recording device, an EPG (Electronic Program Guide) server 201 that distributes program information including a program name and a series name of content to be broadcast, and the like. As described later, the distribution server 220 includes a distribution server 220 that distributes recorded content, and a portable terminal 230 that serves as a means for reproducing recorded content. The personal computer 210 shown in FIG. 1 is set in a user's home or the like, and is connected to the EPG server 201 and the distribution server 220 via a network (for example, the Internet). The user's portable terminal 230 is connected to the above-described network via a wireless access point installed in the vicinity.

  FIG. 2 is a sequence diagram showing the operation of the recorded content viewing system.

  The detailed configuration and schematic operation of the recorded content viewing system will be described below with reference to FIGS.

  In the personal computer 210 shown in FIG. 1, the recording control unit 211 controls the reception operation by the television (TV) broadcast receiving unit 213 according to the reservation information held in the reservation information holding unit 212, and receives the television (TV) broadcast. The moving image data (hereinafter referred to as “recorded content”) obtained in this manner is stored in the recorded content holding unit 214 (shown in FIG. 2 as a procedure for receiving and recording a TV broadcast).

  In addition, the program information holding unit 215 shown in FIG. 1 holds program information acquired corresponding to the content to be recorded. This program information can include, for example, identification information (such as broadcast date and time information and broadcast station identification information) for specifying program content, and detailed information indicating a program name, series name, genre, performer, and the like. . As shown in FIG. 2, such program information is acquired when accessing the above-described EPG server 201 for program recording reservation and referring to a program broadcast schedule or the like according to a user's operation. be able to.

  In the personal computer shown in FIG. 1, the upload control unit 216 transmits the recorded content stored in the recorded content holding unit 214 to the distribution server 220 via the network, and the recorded content storage unit 221 secured in the distribution server 220. The recorded content sent to is stored.

  At this time, the upload control unit 216 reads the program information held corresponding to the recorded content to be transmitted from the program information holding unit 215, adds additional information including this program information to the recorded content, and the distribution server 220. Recorded content with additional information is sent to (see FIG. 2).

  In the distribution server 220 shown in FIG. 1, the classification processing unit 222 classifies the recorded content stored in the recorded content storage unit 221 into a plurality of groups using program information included in the corresponding additional information as key information. A list of recorded contents is created for each time and stored in the list holding unit 225 (shown as a grouping procedure for recorded contents in FIG. 2).

  For example, as illustrated in FIG. 3, the classification processing unit 222 performs recording when the recorded content 1 to n obtained by recording various programs is stored in the recorded content storage unit 221. These recorded contents are allocated to groups corresponding to program names (shown as programs A, B, and C in FIG. 3), and a list of recorded contents stored in the recorded content storage unit 221 is created for each of these groups. Can do. For example, as shown in FIG. 3, the list of recorded contents of each group can be formed from program information added to the recorded contents belonging to the group, and the list holding unit 225 shown in FIG. Corresponding to the above, a list of program information of recorded contents belonging to each group is stored.

  In addition, when new recorded content is stored in the recorded content storage unit 221 from the personal computer 210, the classification processing unit 222 newly starts based on the program name included in the program information added to the recorded content. This recorded content can be added to the group by discriminating the group corresponding to the accumulated recorded content and adding the program information added to the newly accumulated recorded content to the corresponding group list. . Also, when the recorded content of a new program is uploaded for the first time, a new group is created by the classification processing unit 222 corresponding to the program name indicated by the program information added to the newly accumulated recorded content. A list of recorded contents corresponding to the new group is created and stored in the list holding unit 225.

  The list of recorded contents for each group created in this way is passed to the reception processing unit 223 shown in FIG. 1 via the list holding unit 225 and presented to the user in response to a request from the mobile terminal 230. Is done.

  For example, as shown in FIG. 2, when the mobile terminal 230 accesses the distribution server 220 according to the user's operation, the reception processing unit 223 displays the list of recorded contents for each group (see FIG. 3). It is transmitted to the mobile terminal 230 and presented to the user via the display unit provided in the mobile terminal 230.

  When a recorded content to be distributed is specified from the list presented in this way by a user's operation, a distribution request for the specified recorded content is sent from the portable terminal 230 (see FIG. 2). In response to this distribution request, the reception processing unit 223 instructs the distribution control unit 224 to distribute the specified recorded content, and the distribution control unit 224 reads the specified recorded content from the recorded content storage unit 221. And delivered to the requesting mobile terminal 230. By playing the recorded content distributed in this way by using the moving image playback function of the mobile terminal 230, the user can view the program content recorded by the personal computer 210 at home while on the go.

  Further, as described above, in the distribution server 220, the recorded content stored in the recorded content storage unit 221 is managed for each group classified based on the program name and the like, and in response to a request from the user, the group By presenting each, it is possible to assist the user in specifying the desired content.

  When the number of recorded contents stored in the recorded content storage unit 221 is small, the program information added to the recorded contents can be presented as it is for selection by the user. is there. On the other hand, when a large number of recorded contents are accumulated, first, the reception processing unit 223 presents the program name corresponding to each group, and the corresponding recorded content according to the selection of the program name by the user. It is also possible to present hierarchically, such as presenting a list of

  As apparent from FIG. 2, in the recorded content viewing system shown in FIG. 1, the recorded content recorded by the personal computer 210 corresponding to the recording device is uploaded to the distribution server 220, and the recorded content is transferred from the personal computer 210. Instead of delivering to the mobile terminal 230, the delivery server 220 delivers to the mobile terminal 230. Therefore, it is not necessary to keep the personal computer 210 in an operating state in preparation for a distribution request from the portable terminal 230. That is, regardless of the operating state of the personal computer 210, in response to a request from the mobile terminal 230, the recorded content can be distributed and used for playback processing in the mobile terminal 230, and provided to the user.

  As described above, the recording content is distributed from the distribution server 220, so that the distribution server 220 realizes schedule management as will be described later regarding the recording of the program content on the personal computer 210 and the viewing of the recorded content on the mobile terminal 230. can do.

  FIG. 4 shows another embodiment of the recorded content viewing system.

  4 that are the same as those shown in FIG. 1 are given the same reference numerals, and descriptions thereof are omitted.

  As shown in FIG. 5C, the list of recorded content of each group held in the list holding unit 225 shown in FIG. 4 has been reproduced with the corresponding recorded content in the program information of the recorded content belonging to each group. Or a non-reproduced reproduction flag is added.

  This reproduction flag is operated by the reception processing unit 223 when the distribution control unit 224 is instructed to distribute the recorded content in response to a distribution request for the corresponding recorded content from the user's mobile terminal 230, for example. The playback flag is changed from not played back to played back.

  In addition, in the recorded content viewing system shown in FIG. 4, the reservation information held in the reservation information holding unit 212 is distributed by the upload control unit 216 (see FIG. 1) of the personal computer 210 separately from the upload of the recorded content described above. Sent to server 220. As shown in FIG. 5A, the reservation information holding unit 212 shown in FIG. 4 holds the names of programs for which recording operations are reserved and date / time information corresponding to the respective programs. For example, the upload control unit 216 may collectively transmit reservation information related to recording scheduled for the week on a predetermined day of the week, or all the reservation information held in the reservation information holding unit 212. May be sent together.

  In the distribution server 220 shown in FIG. 4, the schedule management unit 226 groups the reservation information received from the personal computer 210 in accordance with the program name as shown in FIG. The recording schedule is managed as described later based on this reservation information. In the schedule holding unit 227, each reservation information is held for each group indicated by the program name, and a completion flag indicating whether or not the reserved recording is completed corresponding to each group. Is provided.

  Hereinafter, a method for managing the schedule related to the recording of the program content and the viewing of the recorded content based on the information held in the schedule information holding unit 227 and the list holding unit 225 shown in FIG. 4 will be described.

  FIG. 6 is a flowchart showing the operation of the schedule management unit.

  The schedule management unit 226 executes the recording schedule update process and the unreproduced content check process shown in FIG. 6A every time new recorded content is stored in the recorded content storage unit 221. On the other hand, the recording schedule check process shown in FIG. 6B is executed at predetermined time intervals by the schedule management unit 226.

  First, processing executed in response to reception of new recorded content will be described (see FIG. 6A).

  When new recorded content is stored in the recorded content storage unit 221 (step 301), the schedule management unit 226 updates the completion flag corresponding to the reservation information of the group to which the newly stored recorded content belongs. Recording is completed (see step 302 in FIG. 5B and FIG. 6).

  At this time, as described above, the new recorded content is classified into a group corresponding to the program name by the classification processing unit 222 shown in FIG. 4 based on the program information included in the additional information. Is added as an untransmitted recorded content to the list of recorded content of the group (see FIG. 5C).

  Next, the schedule management unit 226 refers to the list of recorded content corresponding to the group to which the information related to the new recorded content is added as described above (step 303), and adds it to the recorded content registered in the list. It is determined whether there is an untransmitted content other than the recorded content that has been recorded (step 304).

  For example, as shown in the list of the program C shown in FIG. 5C, in addition to the recorded content corresponding to the newly registered fifth broadcast, the recorded content indicated as unreproduced by the reproduction flag Is affirmative in step 304. In this case, the schedule management unit 226 creates a message that alerts the user that the recorded content accumulated in the distribution server 220 is not watched, and sends an email including this message. By transmitting the message to the user's portable terminal 230, the user is notified of the accumulation of unreproduced recorded content (step 305), and the process is terminated.

  On the other hand, if the determination in step 304 is negative, the schedule management unit 226 skips the process in step 305 and ends the process.

  In this way, by checking the playback flag added to the list of recorded content of the corresponding group in response to reception of new recorded content, the viewing schedule by the user of the recorded content is managed and used for each group. The user can be alerted and the user can be prompted to view the recorded content that has not been viewed.

  If the program name is not included in the reservation information, the program recorded according to the reservation information is determined using the commonality between the recording reservation date and time and the broadcast date and time indicated by the reservation information. Schedule information can also be grouped based on

  On the other hand, looking at all the groups, the number of unplayed recorded contents or the time required for playing them is totaled, and when these values exceed a predetermined threshold set for each group, It is also possible to notify the user of a message that alerts the user that the recorded content is stagnant.

  The destination of the above-mentioned alert message is not limited to the user's portable terminal 230. For example, the alert message is transmitted to an email address registered corresponding to the user, and the user can send the message from the personal computer 210 at home. It can also be confirmed.

  Next, the recording schedule management operation will be described with reference to FIG.

  For example, the schedule management unit 226 starts the recording schedule management process at a predetermined time every day, and first acquires reference date information indicating the current date (step 311).

  Next, the schedule management unit 226 detects reservation information for which recording has failed based on a comparison between the reservation information held in the schedule information holding unit 227 corresponding to each group and the current date and time indicated by the reference date and time information. (Step 312). For example, the schedule management unit 226 includes the recording completion date / time and the current date / time indicated by the reservation information in which the recording operation is not completed by the completion flag among the reservation information of each group held in the schedule information holding unit 227. , And by detecting the recording completion date and time before the current date and time, it is possible to detect the reservation information in which the recording has failed. In addition, when this schedule management part 226 detects recording failure about each reservation information, it compared with the date and time which added predetermined grace time to the recording completion date and time, and was shown in FIG. In the personal computer 210, the determination can be made in consideration of the time from when the recording by the recording control unit 211 is completed until the recorded content is transmitted to the distribution server 220 by the upload control unit 216.

  For example, as shown in FIG. 5B, the schedule information holding unit 227 stores reservation information (see the reservation information of program B in FIG. 5B) indicating the recording completion date and time before the current date and time. In step 312, the reservation information is detected, and in response to this, the schedule management unit 226 records or records a program (program B in the example of FIG. 5B) corresponding to the group to which the reservation information belongs. It is determined that the upload of the recorded content has failed (Yes determination in step 313).

  In this case, the schedule management unit 226 creates a message notifying that the scheduled recording or the uploading of the recorded content has failed for the program content reserved for recording according to the detected reservation information, and sends an email including this message. The message is transmitted to the user's portable terminal 230 (step 314). On the other hand, in the case of negative determination in step 313, the above-described processing in step 314 is skipped.

  Thereafter, the schedule management unit 226 determines whether or not the detection of the reservation information for which recording has failed for all the groups has been completed (step 315). If the determination is negative, the schedule management unit 226 returns to step 312 for the next group. Perform the process.

  In this way, when the process is completed for the reservation information held in the schedule information holding unit 227 corresponding to all groups, the process ends as an affirmative determination in step 315.

  As described above, by periodically checking the reservation information held in the schedule holding unit 227 and notifying the user's portable terminal 230 of the check result, it is possible to reliably detect the failure of the scheduled recording or the upload of the recorded content. This can alert the user to this.

  It should be noted that when the date and time when a plurality of recorded contents recorded in the personal computer 210 shown in FIG. 4 are uploaded is scheduled according to the traffic of the network or the usage status of the personal computer 210, the recorded content is recorded. The date and time when the schedule management unit 226 executes the above-described processing can be set in accordance with the uploading date and time.

  Further, instead of the reserved date and time set corresponding to each program to be recorded, information indicating the date and time when the upload processing of each recorded content corresponding to these programs is scheduled is made via the upload control unit 216. To the distribution server 220 and can be used for the schedule management as described above.

  Further, as in the above-described warning message regarding unsent recorded content, the destination of the message regarding recording failure is not limited to the user's mobile terminal 230, for example, an email registered corresponding to the user It may be transmitted to the address so that the user can confirm from the personal computer 210 at home.

  Further, as in the embodiment described with reference to FIGS. 4 to 6, instead of transmitting the reservation information all at once, in addition to the program information corresponding to the recorded content by the upload control unit 216 of the personal computer 210, Additional information including reservation information related to the next recording reservation can be added to the recorded content, and this reservation information can be used for schedule management processing by the schedule management unit 226.

  In this case, for example, the schedule management unit 226 uses the commonality between the recording reservation date and time and the broadcast date and time indicated by the reservation information to collate the reservation information with the information held in the list holding unit 222. The program to be recorded can be determined, and the schedule information for each group can be updated according to the determination result.

As shown in FIG. 1 and FIG. 4, the configuration in which the program information related to the contents of the recorded content and the reservation information related to the recording reservation is transmitted from the user's personal computer 210 to the distribution server 220 uses the EPG server 201. This is suitable for setting a recording reservation for program content.

And the recording end date and time) and the program identification information including broadcast station identification information (for example, channel number) is held in the recorded content holding unit 214.

  In addition, the moving image data held in the recorded content holding unit 214 is sent to the distribution server 220 via the network after the corresponding program identification information is added by the upload control unit 216 shown in FIG.

  That is, in the recorded content viewing system shown in FIG. 7, the minimum information necessary for specifying the recorded program (the program identification information described above) is added as additional information to the recorded content recorded in the personal computer 210. Thus, it is used for the distribution processing of the recorded content by the distribution server 220.

  On the other hand, the distribution server 220 shown in FIG. 7 includes a program classification processing unit 232 that accesses the EPG server 201 via the network and acquires program information in response to an instruction from the classification processing unit 231. Based on the program information acquired by the program information acquisition unit 232, the classification processing unit 231 performs a process of grouping the recorded content stored in the recorded content storage unit 221 and creating a list of recorded content for each group. Is called.

  In the recorded content viewing system shown in FIG. 7, based on the list of recorded contents created by the classification processing unit 231 based on the program information acquired by the program information acquisition unit 232 from the EPG server 201, the recording content shown in FIG. Similar to the content viewing system, the process of distributing recorded content to the mobile terminal 230 can be managed for each group.

  In a configuration in which processing for obtaining detailed program information from the EPG server 201 is shared by the distribution server 220, and recorded content is grouped and managed based on this program information, program information is transmitted from the personal computer 210 side corresponding to the recording device. Therefore, the present invention can be applied to a case where a user makes a recording reservation by directly specifying a channel and a recording time.

  It should be noted that the viewing flag management shown in FIG. 4C is provided in the list of recorded contents, and the reproduction status of each recorded content is reflected in this list, thereby managing the same viewing schedule management as the recorded content viewing system shown in FIG. Can be realized.

  Further, in the configuration in which the distribution server 220 acquires program information from the EPG server 201, the acquired program information can be used for managing a recording schedule in addition to the grouping process by the classification processing unit 222.

  For example, when the detailed information of the program acquired from the EPG server 201 indicates that there is a subsequent program, the broadcast schedule information indicating the next broadcast date and time is acquired from the EPG server 201, and Based on this, it is possible to estimate when the corresponding recorded content is uploaded from the personal computer 210 and use this estimation result for recording schedule management.

  On the other hand, as with the recorded content viewing system shown in FIG. 4, it is also possible to receive reservation information from the personal computer 210 and manage the recording schedule based on this reservation information.

  In the configurations described in the first embodiment and the second embodiment described above, the process of distributing the recorded content in response to the distribution request from the mobile terminal 230 is shared by the distribution server 220. Therefore, it is not necessary to set the personal computer 210 of the user as a recording device so that it can be activated in response to an operation instruction via the network, and the personal computer 210 is not exposed to external access. Therefore, in the recorded content viewing system configured as described above, it is possible to view a desired program recorded by the user using the personal computer or the like on the go while maintaining the security of the user's personal computer.
