JP5487016B2 - Content reservation control apparatus, content reservation control method, and receiver - Google Patents

Description

  The present invention relates to a configuration and method of content reservation control at a receiver that receives a content distribution service by broadcast waves.

  In the multimedia broadcasting service, content is broadcast to a user's mobile terminal by a download type distribution method called streaming and file casting using broadcast waves. The multimedia broadcasting service is a service in which each content is recorded and stored on a mobile terminal, and the content is viewed at a timing that the user likes. The term “recording” is defined as storing streaming content in a terminal or in an external storage medium connected to the terminal. The term “accumulate” is defined as storing the file casting content in the terminal or in an external storage medium connected to the terminal. Here, in both streaming and file casting systems, the date and time (program guide) at which predetermined content is distributed is determined. Streaming is performed using several channels. File casting does not have the concept of a channel, but uses a different frequency from streaming content broadcast at the same time.

  FIG. 1 is an image of a distribution schedule. In the example of FIG. 1, three channels are prepared for streaming, and streaming content is distributed on each channel while being divided by time. On the other hand, the file casting is set so that the mobile terminal can easily receive the same content by distributing the same content a plurality of times during the distribution period. For file-casting content, a service called broadcast complementation by communication is also conceived in which, when a packet cannot be correctly received by a broadcast wave, a packet dropped by a communication network is received.

  In multimedia broadcasting, free content and paid content that requires the purchase of a license are mixed. Also, in the multimedia broadcasting service, when the user manually performs recording / storage reservation operation from the program guide, the content described in the recommended content list or the like received periodically or as needed on the communication network automatically (user (Without operating anything) co-exists with services that record and store on mobile devices.

  Recording and storage of content provided by the multimedia broadcasting service is performed by decrypting encryption using a key that dynamically changes in association with each channel in real time while receiving the content, and further storing it on an SD card. In this case, it is encrypted and stored with another key. Here, reservations for different channels and different contents may overlap at the same time, but a receiver with limited processing capability, such as a mobile terminal, should store content received from multiple channels at the same time. Is difficult to realize.

  With regard to overlapping reservations, in the conventional reservation method, if there is an overlap in the broadcasting time of different contents, the user has to select which content is to be reserved each time. However, this method is complicated for the user that the user selects each time duplication occurs, and usability is reduced. Furthermore, no action is taken when there is a time zone overlap between the contents in the recommended content list to be automatically reserved. In the simple method of not reserving content when time zones overlap, the user loses the recommended viewing opportunity of the content.

  In the download distribution of content by broadcast waves, when the reservation time of the newly reserved first content and the reservation time of the already reserved second content overlap each other, the same content as the first content is received at the receiver. In this technique, a content that has an image quality that is higher than the image quality allowed by the user and that has a reservation time that does not overlap with the reservation time of the second content is determined and the download reservation of the alternative content is made instead of the first content. (For example, refer to Patent Document 1).

  Also, determine whether the scheduled time of the broadcast that is about to be newly reserved corresponds to the case where the reserved time of the already reserved program is “not overlapping at all”, “partially overlapping”, or “all overlapping” However, if all of them overlap, a new reservation is not made. If some overlaps, the reservation time of the new broadcast is adjusted so that it does not overlap with the already reserved broadcast reservation time. Is also known (see, for example, Patent Document 2).

  However, in any of the above-mentioned documents, reservation control in a situation where streaming distribution and download type file casting coexist is not considered. In addition, reservation control in situations where manual content reservation by the user and reservation for content that is subject to automatic reservation such as so-called “recommended content” coexist, and control that takes into account reservation priority based on the presence or absence of a license, etc. Is not mentioned.

  Therefore, an object of the present invention is to provide a reservation control method with high usability in a content distribution service broadcast using a broadcast wave by a streaming method and a file casting method.

  Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. FIG. 2 shows a configuration of a receiver 200 according to an embodiment of the present invention. The receiver 200 is assumed to be a portable terminal capable of both broadcast reception and communication reception. Types of portable terminals include any portable communication device and portable information device that can be carried, such as a mobile phone and a notebook PC. In addition, some contents provided by broadcast waves and received by the receiver (portable terminal) 200 require a license. Such contents are not saved before the contents are stored in the terminal 200. Alternatively, it is assumed that a predetermined license fee may be charged when viewing content stored in the terminal 200. Furthermore, it is assumed that the receiver (hereinafter referred to as “portable terminal”) 200 receives and stores metadata in advance or periodically for content that is not stored in the terminal 200. Includes the broadcast type, broadcast date and time, presence / absence of license, and type of content.

  The portable terminal 200 includes a broadcast receiving unit 203 that receives broadcast packets by broadcast waves, and a communication receiving unit 208 that receives communication packets via a communication network. The communication reception unit 208 sends metadata and content of the received broadcast packet to the metadata / content management unit 206 and distributes recommended content information to the recommended content list management unit 205. The communication receiving unit 208 sends the recommended content information in the received communication packet to the recommended content list management unit 205. The recommended content list management unit 205 manages the recommended content information as a list, and provides a recommended content list to the schedule management unit 207 in response to a recommendation content list acquisition request from the schedule management unit 207.

  The metadata / content management unit 206 stores and manages metadata and content sent from the broadcast receiving unit 203, and in response to a content storage state request and metadata acquisition request from the schedule management unit 207, the schedule management unit The content storage state and metadata are provided to 207. Of the information included in the metadata, license information for each content is managed by the license management unit 204. The license management unit 204 provides license information to the schedule management unit 207 in response to a license inquiry from the schedule management unit 207.

  The display processing unit 201 receives a user operation, performs screen display processing, and displays a screen on a display unit (not shown). Further, a screen display request from the user or a manual reservation request is sent to the user interface (UI) control unit 202, and a screen display processing request is received from the UI control unit 202. The UI control unit 202 sends a reserved information acquisition request and a reservation request to the schedule management unit 207, and receives reserved information and duplicate information from the schedule management unit 207.

  The schedule management unit 207 receives a reserved information acquisition request and a reservation request from the UI control unit 202, and sends the reserved information and duplicate information to the UI control unit 202. In the example of FIG. 2, the reserved content information is stored and managed in the form of a reservation list 210. Duplicate information is a state indicating whether or not there is a state in which recording / storage reservations of a plurality of contents overlap in a certain reservation time zone. In the embodiment, storage / management is performed in the form of an event schedule list 220. Has been. For convenience, the reservation list 210 and the event schedule list 220 are collectively referred to as a “reservation / schedule list”.

  The schedule management unit 207 updates the reservation list 210 and the event schedule list 220 in the course of updating the broadcast distribution form (streaming) of the content subject to reservation control based on the metadata received from the metadata / content management unit 206. Or file casting) and make reservation adjustments according to the type of mobile phone broadcaster. In addition, it is determined whether the content to be reserved is content that is subject to automatic reservation or content that is manually reserved by the user. For a content that has been manually reserved, for example, a reservation setting flag is set via the display processing unit 201 and the UI control unit 202. The automatic reservation target content is, for example, recommended content (recommended content) sent from a service provider. As will be described later, the schedule management unit 207 determines the priority of the reservation based on the broadcast distribution form of the content and the reservation mode, and updates the reservation / schedule list.

  The schedule management unit 207 also creates a recommended content reservation list (see FIG. 17) to be described later based on the recommended content list acquired from the recommended content list management unit 205 in the process of updating the reservation / schedule list. In creating the recommended content reservation list 250, the content storage status received from the metadata / content management unit 206 and the license information received from the license management unit 204 are referred to. That is, based on the storage status information, it is determined whether or not the content to be reserved is already reserved and stored. Based on the license information, the presence / absence of a license for each content, the necessity of license acquisition, etc. To determine the priority of the recommended content reservation. As a result, the reservation / schedule list is updated based on the recommended content reservation list whose reservation priority is adjusted.

The schedule management unit 207, the recommended content list management unit 205, and the license management unit 204 constitute the content reservation control apparatus 300. FIG. 3 shows reservation control for each content executed by the receiving terminal (mobile terminal) 200 of FIG. It is a flowchart which shows the procedure of. At this time, it is assumed that the schedule management unit 207 of the mobile terminal 200 has a reservation list 210 managed in the state shown in FIG. 4 and an event schedule list 220 managed in the state shown in FIG. The event schedule list 220 in FIG. 5 manages the temporal overlap state of processing (event contents such as recording / accumulation) for the content reserved in the reservation list 210 in FIG. 4 and 5, “ST” indicates streaming, “FC” indicates file casting, and “ch” indicates a streaming channel number.

  Before explaining the flow of FIG. 3, how the reservation list 210 of FIG. 4 and the event schedule list 220 of FIG. 5 are updated will be described with an example.

  Now, the user tries to make a reservation recording on the portable terminal 200 for the content “content ID: 0203, distribution time: 2010/7/11 15: 00-18: 00, distribution mode is streaming (ch1)”. At this time, according to the event schedule list 220 in FIG. 5, the broadcast time from 15:00 to 18:00 overlaps in time with the FC content event times (from 15:00 to 21:00) of 0032, 0002, 0020, and 0045. However, even if the content of 0203 that is streamed (ST) is recorded, the broadcast period of the content 0203 is not entirely occupied by other FC content, so the schedule management unit 207 treats the content of 0203 as a reservation. 4 is updated as shown in FIG. 6, and the event schedule list 220 shown in FIG. 5 is updated as shown in FIG.

  Next, the user continues to make a reservation recording of the content of “content ID: 0067, distribution time 2010/7/11 23: 00-24: 00, distribution form streaming (ch2)”. Since the broadcast time zone from 23:00 to 24:00 does not overlap with the previously reserved content, the schedule management unit 207 treats 0067 as a reservation, and sets the reservation list 210 in FIG. 6 and the event schedule list 220 in FIG. Updates are made as shown in FIGS.

  Next, the user attempts to make a reservation recording of the content of “content ID: 0394, distribution time 2010/7/11 14: 00-18: 00, distribution form file casting (FC)”. At this time, on the event schedule list 220 in FIG. 9, the distribution time zone of the content ID 0394 is already occupied by the reserved recording of the streaming content 0589 and 0203. Therefore, the schedule management unit 207 displays a reservation duplicate message as shown in FIG. 10 on the screen of the mobile terminal 200 via the UI control unit 202 and the display processing unit 201. Assume that the user selects to cancel the reservation of the content 0589 by looking at the display on the screen. The user selection is sent to the schedule management unit 207 via the display processing unit 201 and the UI control unit 202. The schedule management unit 207 updates the reservation list 210 and the event schedule list 220 as shown in FIGS. 11 and 12, respectively, according to the user's selection. Here, it is noted that for the contents of 0010, 0032, 0002, 0020, 0045, a part of their reserved time zones overlaps with 14: 00-15: 00, which is the time when the user canceled the reservation.

  The flow up to this point will be described with reference to the flow of FIG. First, in step S101, the schedule management unit 207 determines whether recommended content information has been acquired. The recommended content is content that is subject to automatic reservation. If the recommended content information is not acquired (NO in S101), it is determined in S103 whether there is a manual reservation request for some content from the user. The manual reservation request from the user is sent to the schedule management unit 207 via the display processing unit 201 and the UI control unit 202 (see FIG. 2). As described in the examples of FIGS. 4 and 5, it is assumed that a reservation request for the ST content 0203 is input from the user (YES in S103). In this case, the process proceeds to S111 via S105.

  In the counter of S105, the i-th content that is the target of the current reservation control out of the number of contents N included in the reservation list is shown. The initial value is i = 0, but i is incremented each time the reservation control for the content is completed. When i <N is satisfied in S111, the process proceeds to S113.

  In S113, it is determined whether there is already another reservation at the broadcast time of the content (0203) to be reserved this time. In the example of FIG. 5, the other four FC contents are already reserved in the broadcast time zone of the content 0203 (YES in S113). Therefore, the process proceeds to S117, and the distribution mode of the content to be reserved (FC distributed content or ST distributed content) is determined. This determination is made based on the metadata sent from the metadata / content management unit 206. In the above-described example, the content 0203 selected by the user is content that is distributed by streaming, so the process proceeds to S119.

  In S119, it is determined whether or not ST is included in the previously reserved content. In the example of FIGS. 4 and 5, since the four contents reserved in the time zone overlapping with the broadcast time of the content 0203 are FC contents (NO in S119), the process proceeds to S121.

  In S121, it is determined whether or not the distribution period of the previously reserved FC content overlaps with the reserved recording time of the ST content to be reserved this time. In the example of FIGS. 4 and 5, the broadcasting time zone of the ST content 0203 is 15:00 to 18:00 with respect to the reservation time zone 15:00 to 21:00 of the FC contents 0032, 0020, 0002, and 0045. No (NO in S121). Accordingly, the process proceeds to S123, where the content 0203 is treated as a reservation, the reservation list 210 and the event schedule list 220 are updated as shown in FIGS. 6 and 7, and the value of i is incremented.

  On the other hand, as described with reference to FIGS. 6 and 7, when the user manually reserves ST content 0067 (YES in S103 and S111), there is no other reservation at the broadcast time of content 0067 (S113). NO), the process proceeds to S115 and is treated as a reservation, the reservation list 210 and the event schedule list 220 are updated as shown in FIGS. 8 and 9, and i is incremented.

  Further, as described with reference to FIGS. 8 and 9, when the user manually reserves the FC content 0394 (YES in S103 and S111), the ST content 0589, 0203 is already in the distribution time zone of this content. Is reserved (YES in S113). The distribution form of the content 0394 is file casting (FC in S117), and the distribution time zone from 14:00 to 18:00 is filled with ST contents 0589 and 0203 (YES in S125). Accordingly, the process proceeds to S129, and it is determined whether the reservation target content is content that is to be automatically reserved or manually reserved content. In this case, since the FC content 0394 has been manually selected and selected (manual determination in S129), the process proceeds to S131, and the message 230 of FIG. 10 is displayed. Then, according to the user's selection, the reservation list 210 and the event schedule list 220 are updated as shown in FIGS. 11 and 12, and i is incremented.

  Next, processing when the communication receiving unit 208 or the broadcast receiving unit 203 of the mobile terminal 200 receives recommended content information via communication or broadcast waves will be described. FIG. 13 shows an example of the recommended content information list 240 received by the mobile terminal 200. The recommended content list management unit 205 manages the recommended content information received from the broadcast receiving unit 203 and the communication receiving unit 208 as a list 240 as shown in FIG. In the recommended content information list 240, a recommended level is associated with each recommended content. When the schedule management unit 207 receives the list 240 from the recommended content list management unit 205, the schedule management unit 207 confirms the metadata managed in advance by the metadata / content management unit 206 for each content ID included in the list 240, and broadcasts it. Check the date, delivery format, and license format. As license forms, it is assumed that there is no license (free) and that there is a license setting (charged). For the content determined to have a license setting, the license management unit 204 is further referred to to confirm whether the license has been purchased at this time or whether a license purchase is necessary (not purchased). As a result, the license status can be classified into free, purchased, and purchase required.

  Next, the schedule management unit 207 confirms the storage state of the content with the metadata / content management unit 206. Here, a method in which the server confirms the storage state in advance can be considered, but the broadcast wave is one-way communication, and the server cannot determine whether or not the mobile terminal has received each content. Therefore, the recommended content information is transmitted from the server to the mobile terminal 200 without considering which content is stored in each mobile terminal 200. Then, it is determined whether the content is stored on the mobile terminal 200 side or not stored.

  In accordance with the above, the schedule management unit 207 creates a recommended content list 250 as shown in FIG. Next, based on the list 250, priorities for setting reservations for each content are given. First, the contents of IDs 0234 and 0183 determined to have been stored (ST recorded or already stored in FC) are excluded from reservation targets because it is not necessary to make reservation settings. Among the remaining contents, the priority is increased for contents for which licenses have already been purchased. As a result, the list 250 is rewritten as shown in FIG. Furthermore, the priority of the ST content is increased between the purchased content and between the free or purchase-needed content. This is because the distribution time for FC is set to be long, and if it is possible to receive even a part of it, it is possible to receive a packet that has been dropped due to broadcast complementation in the communication network. As a result, the list 250 is rewritten as shown in FIG.

  Further, while ensuring the above priorities, the items are rearranged in descending order of “recommendation”. High “recommendation” is content that the service provider wants to show to the user, and it is necessary to secure viewing opportunities for the user or suppress loss of viewing opportunities. Therefore, the recommended content list 250 is rearranged in consideration of the “recommendation degree”, and finally the recommended content reservation list 250R shown in FIG. 17 is created. The recommended content reservation list 250R may be managed by the recommended content list management unit 205. The schedule management unit 207 performs reservation setting according to the flow shown in FIG. 3 in order of the higher-order contents in the recommended content reservation list 250R.

  Returning to FIG. 3, the recommended content information is acquired in S101 (YES in S101), and the recommended content list 250 is created in S107 as shown in FIGS. In S109, a final recommended content reservation list 250R is created. The number of contents in the recommended content reservation list is N, and the content targeted for reservation control this time is the i-th content. The initial value of i is 0, and i is incremented each time a reservation control process for content is performed. In S111, i <N is satisfied, and the process proceeds to S113.

  For the content 0006 with the highest priority in the recommended content reservation list 250R of FIG. 17, it is determined whether there are other reservations that overlap at the broadcast time of this content. Since the broadcast time of the recommended content 0006 does not overlap with the reservation time of other content managed in the event schedule list 220 of FIG. 12 (NO in S113), the process proceeds to S115, where the reservation is made and i is incremented. Since there is no overlap with the next recommended content 0183, S111 and S113 are repeated, and the reservation setting is performed as it is in S115. As a result of such reservation control, the reservation list 210 and the event schedule list 220 managed by the schedule management unit 207 are updated as shown in FIGS.

  Next, reservation setting for the recommended content 0263 is performed. In the determination of S113, it is determined that the accumulated events overlap on the event schedule list 220 of FIG. 19 during the broadcast time 13: 00-14: 00 of the content 0263 (YES in S113). Since the distribution form of the recommended content 0263 is ST (ST determination in S117), it is determined in step S119 whether the previously reserved content is ST. In this example, the contents related to the overlapping accumulation reservation event are FC contents 0394, 0010, 0032, 0002, 0020, 0045 (NO in S119).

  Therefore, the process proceeds to S121, and it is determined whether or not there is an FC that has been reserved previously that has a distribution period that overlaps with the broadcast time of the recommended content 0263 that is the current control target. Among the overlapping FCs, 15: 00-18: 00 of the distribution time 14: 00-18: 00 of the content 0394 is already occupied by the reserved recording of the ST content of 0203 (see the reservation list in FIG. 18). ). If a reservation of 13: 00-14: 00 is set in the recommended content 0263 in this state, all the delivery times of the FC content 0394 overlap (YES in S121). Therefore, the process proceeds to S129.

  In S129, it is determined whether the reservation of the content to be processed this time has been manually reserved by the user or is subject to automatic reservation. In this example, 0263 is recommended content, which is a target of automatic reservation (determined “automatic” in S129). Therefore, the reservation of the recommended content 0263 is put on hold in S133. However, this content is “recommended content”, and the service provider wants to give the user “awareness”. Therefore, i is incremented by displaying it as a recommendation for reservation on the top screen when the user starts the application next time.

  FIG. 20 shows an example of the reservation recommendation display 270. Such a display image may be displayed as an icon on the standby screen of the mobile terminal 200.

  For the ST content 0284 having the fourth highest reservation priority, the distribution time is 22: 00-23: 30. This is because the delivery time of the ST content 0183 overlaps, so that the determination is YES in S119 via S113 and S117, and it is determined that the content is an automatic reservation target content in S129. As a result, 0284 is also treated as a reservation hold in S133, and is displayed as a reservation recommendation on the top screen when the user starts the next application or on the standby screen of the mobile terminal.

  Also for the content 0033 having the fifth highest priority, the broadcasting time of 9:00 to 10:00 is already occupied by the ST content recording reservation of ID 0006 (S113, YES through S117, YES in S119, “ In step S133, the reservation is suspended, and the reservation recommendation display 270 is displayed on the top screen when the user activates the next application or on the standby screen of the mobile terminal 200.

  Regarding the last content 0491 in the recommended content reservation list 250R, the time zone from 9:00 to 10:00 in the distribution time 4:00 to 10:00 overlaps with the ST content 0006 (YES in S113). Since the content 0491 is FC content (FC determination in S117), as long as the distribution time does not overlap with another content (NO in S125), it may be received in a non-overlapping time zone. Therefore, it is treated as a reservation in S127, an accumulation reservation is made only during a time when there is no overlap with other contents, and i is incremented. As a result, the reservation list 210 and the event schedule list 220 are updated as shown in FIGS. 21 and 22, respectively.

  As described above, the reservation control procedure differs depending on the distribution mode of streaming distribution or FC distribution, and whether the content reservation request is manually selected by the user is automatically set as a reservation target. The reservation control procedure differs depending on whether or not there is. Furthermore, for the recommended content subject to automatic reservation, the priority order of reservation is adjusted according to the presence / absence of a license, the necessity of payment of a license fee, the recommended level (recommendation level), and the like.

Such reservation control secures an opportunity for content viewing, suppresses the complexity of operation, and improves the usability of content reservation in the mobile terminal 200.
Note that the schedule management unit 207 in FIG. 2 includes “content content broadcast format determination unit”, “reservation duplication determination unit”, “reservation / schedule list update unit”, and “priority determination unit” described in the claims. Is equivalent to.

  The present invention can be applied to adjustment and control of overlapping content reservations in a content distribution system using broadcast waves.
