Description

  The present invention relates to a broadcasting system in which program information including broadcast time, program name, etc. is multiplexed on multimedia content data including audio and video, and in particular, content data desired by a user is automatically selected from the program information. And a receiver desired program composition method.

  In current digital broadcasting, BS / CS digital broadcasting, CATV, terrestrial digital broadcasting, and the like are performed, and content provided to users tends to increase. For the user, as the content that can be viewed increases, the content that the user wants to view must be selected from the enormous amount of content, which causes a problem that it is very troublesome.

  In view of such a problem, Patent Document 1 discloses a technique for automatically searching for a content desired by a user and broadcasting only the corresponding content. This technology uses the MPEG2-TS (Transport Stream) method currently used in digital broadcasting. In this MPEG2-TS system, a plurality of video / audio are multiplexed in a single transport stream and transmitted. When multiplexing, program information such as program name, content broadcast time, and program content introduction data can be multiplexed in the same stream in addition to video and audio. The contents to be viewed are narrowed down by inputting the genre and program name of the contents desired by the user for the program information. As a result, the user can easily select desired content data.

In recent years, receivers equipped with storage media such as HDD (Hard Disk Drive) and DVD (Digital Versatile Disk) have been developed, and digital broadcast streams can be stored in a format that includes program information. It has become. In these apparatuses, the program information of the content desired by the user is automatically searched on the receiving apparatus side and stored in a storage medium (see, for example, Patent Document 2).
JP-A-11-187324 (page 6, FIG. 1) JP-A-11-196385 (page 6-8, FIG. 1)

  However, in a receiving apparatus having an automatic recording function as in the technique disclosed in Patent Document 2, content data desired by the user is mechanically stored in a storage medium, and stored in the storage medium. A function for making it easy for the user to view the received content data is not realized.

  Further, by having the function of storing the content data, in addition to what is broadcast in real time for the user, the content data stored in the storage medium becomes a viewing target. In other words, it can be said that it becomes increasingly difficult for the user to find the content data that the user wants to view most.

  In view of such problems, an object of the present invention is to provide a receiving device that includes a storage medium and has a function of automatically selecting content data that the user wants to view, so that the user wants to view from the selected content data. It is an object of the present invention to provide an apparatus and a configuration method for automatically configuring a user desired program.

  In order to achieve the above object, the present invention employs the following configuration.

  The first receiving device (corresponding to claim 1) according to the present invention includes a user desired program selection unit and a user preference input unit in addition to a data receiving unit, a decoding / output unit and a storage unit provided in a conventional receiving device. The data receiving unit receives content data including a plurality of video / audio and stream data in which program information such as a program name and program content is multiplexed into one stream. The user preference input unit inputs user preferences such as the program name of the content data that the user wants to view and the genre of the content, and the user desired program selection unit searches for the program information according to the input user preference to obtain the desired content. Data is selected as user-desired content data. In a time zone when the content data desired by the user is not broadcast, the content information that matches the user's preference is searched for the program information in the storage medium, and if there is a match, the program information is handled. Content data is incorporated as user-desired content data.

  The second receiving device (corresponding to claim 2) according to the present invention further includes a user viewing time input unit for inputting a time zone for the user to view in the first receiving device. The user desired program selection unit selects content data that matches the user preference input by the user preference input unit and the time zone input by the user viewing time input unit with respect to the program information received by the data reception unit. It is configured as follows. By notifying the user desired program selection unit of the user viewing time input in the user viewing time input unit, content data that the user wants to view most during the viewing time is preferentially selected when searching for program information.

  According to a third receiving apparatus of the present invention (corresponding to claim 3), in the first or second receiving apparatus, the data received by the data receiving unit is stored in a storage medium or output to a decoding / output unit. A data output switching unit for switching between the two. The data output switching unit receives the result selected by the user desired program selection unit, and sends the selected content data to the decode / output unit to be broadcast as the user desired content data or to the storage unit Switch whether to store in the storage medium. When sending to the storage unit, program information corresponding to the stored content data is also stored.

  According to a fourth receiving apparatus (corresponding to claim 4) of the present invention, in the first to third receiving apparatuses described above, the user desired program selecting section indicates that content data in the storage medium has been added or deleted. A storage medium change notification unit for notification is provided. When the user adds or deletes content data in the storage medium, the program information of the changed content data and a notification that the content data in the storage medium has been changed are selected from the storage medium change notification unit by the user desired program. To the part. Upon receiving the notification, the user desired program selection unit reconstructs the user desired content data.

  According to a fifth receiving apparatus (corresponding to claim 5) of the present invention, in the first to fourth receiving apparatuses, a user-desired program list showing a configuration of user-desired content data is further created, and electronic program information A user-desired program list creation unit is provided for display in addition to (EPG). The user desired program list creation unit receives the program information of the content data selected by the user desired program selection unit, and creates a user desired program list.

  A sixth receiving device according to the present invention (corresponding to claim 6) is a receiving device comprising a storage medium change notifying unit of the fourth receiving device and a user desired program list creating unit of the fifth receiving device. When the content data in the storage medium is changed, the user desired program list is reconstructed. When the user adds or deletes content data in the storage medium, the program information of the changed content data and a notification that the content data in the storage medium has been changed are selected from the storage medium change notification unit by the user desired program. Notify the department. Upon receiving the storage medium change notification, the user-desired program selection unit reconstructs user-desired content data. As a result of the reconfiguration, the updated user desired program list is displayed by notifying the user desired program list creating unit of the program information of the selected user desired content data.

  A first user-desired program composition method according to the present invention (corresponding to claim 7) is a method for constructing user-desired content data from a result of searching program information of content data that matches the user preference input by the user. . In this method, content data matching the user preference is selected by searching the program information of the content data received by the data receiving unit, and is listed in time series. In order to incorporate the content data in the storage medium into the broadcast idle time of the content data desired by the user, the program information of the content data in the storage medium is searched, and the content data that matches the user preference is selected. According to the selected result, the content data in the selected storage medium is incorporated in the broadcast free time of the content data desired by the user.

  The second user-desired program composition method according to the present invention (corresponding to claim 8) selects content data having overlapping broadcast times when configuring user-desired content data in the first user-desired program composition method. This is a user-desired program composition method. As a result of searching the program information of the content data received by the data receiving unit, when a plurality of content data with overlapping broadcast times are selected, the content data that best matches the user preference is selected from among the content data. As a result, the selected user-desired content data is broadcast in real time, and the other content data and the corresponding program information are notified to the data output switching unit so as to be stored in the storage medium.

  The third user-desired program composition method according to the present invention (corresponding to claim 9), in the first and second user-desired program composition methods, does not have sufficient broadcast idle time for incorporating the content data in the storage medium. This is a program composition method. The user-desired content data is listed in chronological order and the broadcast idle time is calculated. If the broadcast time of the user-desired content data is shorter than the broadcast time of the content data in the storage medium, the content data selected in the search for the previous user-desired content data is temporarily stored in the storage medium, The time for incorporating the content data in the storage medium is secured by shifting the broadcast time of the content data.

  The fourth user-desired program composition method according to the present invention (corresponding to claim 10) is the program in the first user-desired program composition method in the case where there is not enough free time for incorporating the content data in the storage medium. Configuration method. 8. The configuration method according to claim 7, wherein content data desired by the user is listed in time series, and the broadcast idle time is calculated. When the broadcast time of user-desired content data is shorter than the broadcast time of the content data in the storage medium, the content data selected from the content data in the storage medium is divided by time It is incorporated in the broadcast free time of user-desired content data.

  According to a fifth user desired program configuration method (corresponding to claim 11) of the present invention, content data to be broadcast in real time in a user desired program is determined, and program information and user preference are set when embedding content data in a storage medium. From the above, by adding a priority to each content data, the method of embedding the content data in the storage medium is changed.

  A sixth user-desired program composition method according to the present invention (corresponding to claim 12) is a user-desired program reconstruction method for the case where the user deletes content data in the storage medium in the sixth receiving apparatus. In this method, when the user receives a notification that the content data in the storage medium has been deleted, it is first determined whether or not the deleted content data is registered in the user desired program. If it is not registered in the user-desired program, it is not necessary to reconstruct the user-desired content data. When the content data to be deleted is registered in the user-desired program, the content data to be deleted is deleted from the user-desired program, and the time is set as the broadcast free time of the user-desired content data. As a result of the deletion, processing for incorporating the content data in the storage medium is performed by using the third to fifth methods at a portion where the broadcast idle time is reached.

  The seventh user-desired program composition method according to the present invention (corresponding to claim 13) is a user-desired program reconstruction method when the user adds new content data to the storage medium in the sixth receiving apparatus. is there. In this method, when the user adds new content data to the storage medium, the priority of the added content data is set by checking the user preference. If the added content data is worth registering as a user-desired program, the user-desired content data after the added time is reconstructed. In addition, when adding content data in this method, program information is always stored together.

  According to the first receiving apparatus, the user inputs a keyword (program name, content genre, etc.) of the content data he / she wants to view without having to search for content data he / she wants to view from a lot of content data. Only the desired content can be viewed. Further, when the content data desired by the user is not broadcast, the content data stored in the storage medium can be automatically viewed.

  According to the second receiving device, it is possible to perform a program search more detailed than the first receiving device by inputting a time zone in which the user can view, and the input user preference and user viewing time. By combining with, it is possible to specify the type of content to be viewed according to the time zone.

  According to the third receiving apparatus, when a plurality of pieces of user-desired content data that overlap with each other are selected, the other content data is stored in the storage medium while viewing the content that best matches the user preference. It is possible to view the content desired by the user without leaking.

  According to the fourth receiving apparatus, even when the user deletes the content data registered in the user-desired program or when new content data is added to the storage medium, the user's hands are not bothered. It becomes possible to reconstruct user-desired content data. As an example of the effect, when it is determined that content data that does not match the user preference is included in the user-desired program, the user-desired user-desired content data is reconstructed only by deleting the content data. Is possible.

  According to the fifth receiving device, the future configuration of user-desired content data automatically selected in the receiving device is displayed in advance as a user-desired program list, so that the user can actually view the user-desired content. Before you start, you can know what content will be broadcast. Further, the user can determine in advance that the user's preference is not met. As a result, if a new user preference is input, it becomes possible to reconstruct user-desired content data.

  According to the sixth receiving apparatus, when the content data is added to or deleted from the storage medium so as to meet the user's preference, and as a result, the configuration of the content data desired by the user is changed, the user actually By simply referring to the user desired program list before viewing the user desired content, it becomes possible to know the configuration of the content data desired by the user thereafter.

  According to the first user-desired program configuration method, the user selects only the content data that he / she wants to view from the content data stored in the storage medium and the many content data received by the data receiving unit. Without this, it is possible to view only the content that the user wants to view.

  According to the second user-desired program configuration method, when a plurality of items that overlap in time are selected as a result of selecting content data that matches user preferences, the user views without missing any of those contents. It becomes possible.

  According to the third or fourth user-desired program configuration method, no matter how short the idle time of the content data desired by the user is, the free time of the broadcast can be reduced as much as possible, and the user can watch the most during that time period. The user-desired content data can be configured so that the desired content can be broadcast.

  According to the fifth user-desired program configuration method, it is possible to save the user from having to specify how to incorporate the storage medium in the broadcast idle time of the user-desired content data, and the user can automatically input the user preference by simply inputting the user preference. It is possible to view content with a program structure that suits the taste.

  According to the sixth user-desired program configuration method, when the user deletes content data in the storage medium, there is no problem that content data does not exist although it is registered in the user-desired program. For the user, when content data that does not match the preference exists in the user-desired program, it is possible to obtain a program configuration that matches the user preference simply by deleting the content data.

  According to the seventh user-desired program configuration method, when new content data is added to the storage medium, the user can reconfigure the user-desired content data including the added content data, so that the user can The added content can be viewed without missing the content data received at.

  Embodiments of a receiving apparatus and a user-desired program composition method according to the present invention will be described below in detail with reference to the drawings.

(First embodiment)
Hereinafter, a receiving apparatus according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the receiving apparatus in the first embodiment, and FIG. 2 is a conceptual diagram of the user desired program configuration method at that time.

  The receiving device 0100 of this embodiment includes a data receiving unit 0101, a decoding / outputting unit 0102, a storage unit 0103, a user preference input unit 0104, and a user desired program selection unit 0105. The data receiving unit 0101 receives content data including a plurality of video / audio and program information including data such as a program name, a program broadcast time, and program contents. The content received by the data receiving unit 0101 is transmitted to the decoding / output unit 0102. In the decoding / output unit 0102, only the content data of the channel specified by the user is extracted from the content data received by the data receiving unit 0101, the audio data is decoded as audio, and the video data is decoded as video. Output from the device 0100. The TV monitor / speaker 0106 connected to the receiving apparatus 0100 may be incorporated in the receiving apparatus 0100 or may be connected to the outside. The program information received by the data receiving unit 0101 is transmitted to the user desired program selection unit 0105. The user desired program selection unit 0105 searches for program information of content data that matches the user preference input in the user preference input unit 0104, and decodes the content data that matches the user preference as user desired content data. Notify the output unit 0102.

  In the conceptual diagram of FIG. 2, the content data that matches the user preference are the real-time contents RTC-1 and RTC-2 of the program list 0201. In addition, as a result of selecting user-desired content data in the user-desired program selection unit 0105, content data stored in the storage medium in the storage unit 0103 for a time zone when there is no content data matching the user preference. And the program information is retrieved and notified to the decoding / output unit 0102 so as to be incorporated into the broadcast free time of the content data desired by the user and broadcast. Upon receiving the notification, the decoding / output unit 0102 transmits the content data designated by the user desired program selection unit 0105 to the outside as video / audio. In the conceptual diagram of FIG. 2, the content data in the selected storage medium is SC-1 and SC-2. The user-desired program finally created is shown in 0203, and the user can view the content he / she desires without searching for a lot of content.

  Further, FIG. 3 shows a receiving apparatus in which a user viewing time input unit for inputting a user's desired content viewing time is added to the receiving apparatus of FIG. Reference numerals 0300 to 0306 are the same as the configurations of 0100 to 0106 in FIG. The newly added user viewing time input unit 0307 is a block for inputting not only the user preference but also the time zone during which the user views the content desired by the user. It is also possible to change the genre of the content data to be selected according to the time zone specified by the user by inputting the user viewing time and combining it with the user preference.

  FIG. 4 shows an example when user preference is input using the user viewing time input unit 0307 and the user preference input unit 0304. In FIG. 4, the user viewing time is set to the user viewing time A and the user viewing time B, the user preference “sports” “baseball” is set in the user viewing time A, and “movie” is set in the user viewing time B. A user preference “Suspense” was set. In this receiving apparatus, content data that matches the user preference of “sports”, “baseball”, “movie”, and “suspense” is selected from the program information received by the data receiving unit 0301, and each user viewing time is selected. It is possible to configure content data that matches the user preference of the user. In the present invention, the number of user preferences to be input and the number of user desired programs are not defined.

  A method for configuring user-desired content data will be described with reference to the flowchart of FIG. In this description, the content information that matches the user preference is selected from the program information received by the data receiving units 0101 and 0301, and the content in the storage medium is set for the time zone when the broadcast is idle. A method of incorporating content data will be described. In step S0501, it is determined whether all the currently acquired program information has been searched. If all currently acquired program information is searched, the configuration process ends. If there is an unsearched part, the process proceeds to step S0502. In step S0502, it is determined whether there is a broadcast vacant time in the user-desired program that is currently configured. If there is no broadcast vacant time, the configuration process is terminated. If there is a broadcast vacant time, the process proceeds to step S0503. In step S0503, the broadcast free time of the user-desired content data currently configured is calculated, and the broadcast time of the content data stored in the storage medium is acquired from the program information in the storage medium in step S0504. In step S0505, the broadcast free time is compared with the broadcast time of the content data in the storage medium. If there is anything that falls within the broadcast free time, the content data is set as the user-desired content data in step S0506, and the time Register with. If there is nothing that can be accommodated in the broadcast idle time, the process returns to step S0501 to search for content data in the storage medium to be incorporated in the next broadcast idle time. When there are a plurality of content data that can be accommodated in the broadcast idle time, the content data that most closely matches the user preference is incorporated.

(Second Embodiment)
Hereinafter, a receiving apparatus according to a second embodiment of the present invention will be described with reference to the drawings. FIG. 6 is a block diagram showing the configuration of the receiving apparatus in the second embodiment.

  The receiving apparatus according to the present embodiment includes a data output switching unit 0608 for switching the data output destination in addition to the receiving apparatus according to the first embodiment described above, and other block configurations are described in FIG. It is the structure similar to the code | symbol 0300-0307.

  The data output switching unit 0608 switches whether to transmit the content data to the storage unit 0603 or to the decoding / output unit 0602 as a result of selection by the user desired program selection unit 0605.

  With this configuration, when the user cannot view the content data selected by the user-desired program selection unit 0605, it is possible to temporarily store the content data in a storage medium. It is possible to reduce oversight. One example thereof will be described with reference to FIG.

  In the program list 0701 in FIG. 7, when the two content data of the real-time contents RTC-1 and RTC-2 match the user preference and are selected as the user-desired content data, since the broadcast time overlaps, the two content data It is impossible to broadcast simultaneously. In the present embodiment, a user-desired program is selected so that what matches the user preference is selected from the program information of each content data of the real-time contents RTC-1 and RTC-2, and what is desired to be viewed in real time is preferentially broadcast in real time. Register with. The other content data (real-time content RTC2 in the case of FIG. 7) is temporarily stored in the storage medium 0702 and broadcast in a time zone after the broadcast of the real-time content RTC-1 is completed.

  With the above method, more content data that matches the user preference can be registered as the user desired program 0703, and the user can view more content that matches the preference.

  When entering user preferences, real time is required by creating a flag such as “view only in real time” or “you can always watch it, so you can turn it around”. For example, news or sports programs Is preferentially viewed in real time and may be rotated later, such as a movie or a drama, for example, it is possible to always store what is desired to be viewed in a storage medium or register it in a user-desired program.

  In the following, when the content data in the storage medium is incorporated in the broadcast idle time using the receiving device of the second embodiment, the operation method when there is not enough broadcast idle time for the content data in the storage medium Will be described with reference to the drawings.

  In FIG. 8, real-time contents RTC-1 and RTC-2 are selected from the program list 0801 as user-desired contents data to be broadcast in real time in the user-desired program selection unit 0605. After that, it is assumed that the content data in the storage medium 0802 is incorporated into the broadcast idle time between the real-time contents RTC-1 and RTC-2. At this time, any content data stored in the storage medium 0802 is longer than the broadcast free time. In such a case, the priority of the real-time content RTC-2 scheduled to be broadcast in real time is compared with the priority of the content data SC-2 in the storage medium 0802. If the content data SC-2 is the user If it is determined that it matches the preference, or if it is determined that it is not necessary to broadcast the real-time content RTC-2 in real time, the real-time content RTC-2 is temporarily stored in the storage medium 0802, thereby the content data SC- Thus, it is possible to ensure a broadcast free time for incorporating 2.

  The priority referred to here indicates which matches the user preference. For example, even if a point is added to each user preference input by the user preference input unit 0604 and a user with a higher total user preference point that matches each content is determined to be content data with higher priority. good. It is also possible to add an absolute condition such as “a content including this user preference is always viewed in real time”. The present invention has no restrictions on the types of user preferences and how to prioritize content data.

  The user desired program configuration method described with reference to FIG. 8 will be described with reference to the flowchart of FIG. In this description, content data desired by a user who has already selected content data to be broadcast in real time that matches the user preference among the data received by the data receiving unit 0601 is input.

  In step S0901, it is determined whether all the currently acquired program information has been searched. If all the program information currently acquired has been searched, the configuration process is terminated. On the other hand, if there is an unsearched part, the process proceeds to step S0902. In step S0902, it is determined whether there is a broadcast vacant time in the user-configured program that is currently configured. If there is no broadcast vacant time, the configuration process is terminated. If there is a broadcast vacant time, the process proceeds to step S0903. In step S0903, the time until the next real-time content (RTC) in the user-desired program that is currently configured is calculated, and in step S0904, the content data stored in the storage medium is broadcast from the program information in the storage medium. Get time. In step S0905, the broadcast idle time is compared with the broadcast time of the content data in the storage medium 0802. If there is content data that falls within the broadcast idle time, the content data is set to the user-desired content data in step S0906. register. On the other hand, if there is nothing that can be accommodated in the broadcast vacant time, in step S0907, the priority of the real-time content for which the current broadcast vacant time is determined and the content data in the storage medium 0802 are compared. If there is content data in the storage medium to be viewed, in step S0908, the content data in the storage medium 0802 is registered as user-desired content data at that time, and real-time content in which the broadcast time is shifted is determined in step S0909. While registering as content data in the storage medium 0802, the content data is actually stored in the storage medium 0802. On the other hand, if there is no content data in the storage medium having a higher priority than the real-time content in step S0907, it is determined that there is no content data to be incorporated in the broadcast idle time, and the process returns to step S0901.

  In the user-desired program configuration method described with reference to FIG. 9, it is unclear whether or not the real-time content once stored in the storage medium is selected as the user-desired content data, but when storing the real-time content in the storage medium By setting the priority to a high value or adding information indicating that broadcasting is performed immediately after the content data in the storage medium replaced with real-time content, the broadcast time of real-time content is delayed. It can also be prevented.

  Next, another method proposed in the present invention will be described with reference to the drawings with respect to an operation method when there is not enough broadcast idle time for content data in the storage medium.

  In FIG. 10, real-time contents RTC-1 and RTC-2 are selected from the program list 1001 as user-desired content data to be broadcast in real time in the user-desired program selection units 0105, 0305, and 0605. After that, it is assumed that the content data in the storage medium 1002 is incorporated into the broadcast idle time between the real-time contents RTC-1 and RTC-2. At this time, any content data stored in the storage medium 1002 is longer than the broadcast free time. Therefore, content data that matches the user preference is selected from the content data in the storage medium 1002 and divided into sizes that can be incorporated into the broadcast idle time. This division fills in the broadcast idle time. In FIG. 10, the content data selected from the storage medium 1002 is SC-2, and the content data SC-2 is divided into SC-2 ′ and SC-2 ″, whereby real-time content RTC-1 and RTC- It is possible to fill in the broadcast free time between the two.

  This method is based on the premise that the content data in the storage medium can be divided into arbitrary sizes. In the MPEG2-TS system mainly used in the current digital broadcasting, data sent as a transport stream is dropped into an elementary stream (ES) format, and the elementary stream is decoded, thereby enabling video and audio. , Get program information. In this MPEG2-TS broadcast, video and audio data can be divided into a certain size. Further, the user-desired program configuration method described with reference to FIG. 10 can also be realized by a receiving apparatus that does not include the data output switching unit described with reference to FIG. 1 or FIG.

  The user desired program configuration method described with reference to FIG. 10 will be described with reference to the flowchart of FIG. In this description, it is assumed that content data that matches user preferences and is broadcast in real time has already been selected as user-desired content data among the data received by the data receiving units 0101, 0301, and 0601.

  In step S1101, it is determined whether all currently acquired program information has been searched. If all the program information currently acquired has been searched, the configuration process is terminated. On the other hand, if there is an unsearched portion, the process proceeds to step S1102. In step S1102, it is determined whether there is a broadcast vacant time in the user-configured program that is currently configured. If there is no broadcast vacant time, the configuration process is terminated. If there is a broadcast vacant time, the process proceeds to step S1103. In step S1103, the broadcast idle time until the next real-time content is acquired. In step S1104, the broadcast time of the content data stored in the storage medium is acquired from the program information in the storage medium. In step S1105, the broadcast idle time is compared with the broadcast time of the content data in the storage medium. If there is content data that fits in the broadcast idle time, the content data is set to the user-desired content data in step S1106. register. On the other hand, if there is nothing that can be accommodated in the broadcast free time, it is determined in step S1107 whether there is content data that can be divided among the content data in the storage medium. If there is content data in the storage medium that can be divided, the content data is divided in step S1108 and registered before and after the current real-time content in step S1109. In step S1107, if there is no content data in the storage medium that can be divided, it is determined that there is no content data that fills the broadcast idle time, and the process returns to step S1101 to search for the next broadcast idle time.

  In the description of this embodiment, the user-desired program configuration method of FIGS. 8 and 9 and the user-desired program configuration method of FIGS. 10 and 11 have been described as being different from each other, but the above two methods are combined. It is also possible to use it. In addition, by referring to program information and user preferences, specifying viewing priority for each content data, and automatically changing how to incorporate the content data in the storage medium, without burdening the user Thus, it is possible to obtain content data that matches the user preference.

(Third embodiment)
A receiving apparatus according to the third embodiment of the present invention will be described below with reference to the drawings. FIG. 12 is a block diagram showing the configuration of the receiving apparatus according to the third embodiment.

  The receiving apparatus according to the present embodiment adds new content data to the storage medium and deletes content data in the storage medium with respect to the receiving apparatus according to the second embodiment. The storage medium change notification unit 1209 for notifying the user desired program selection unit 1205 is provided, and the other block configuration is the same as the reference numerals 0600 to 0608 described in FIG.

  By providing the storage medium change notification unit 1209, even if the user deletes content data in the storage medium at an arbitrary timing, or when new content data is added to the storage medium, the user-desired content Data can be reconstructed.

  Hereinafter, a case where content data in the storage medium is deleted and a case where new content data is added to the storage medium will be described with reference to the drawings.

  First, a user-desired program reconstruction method when content data in the storage medium is deleted will be described. FIG. 13 is a conceptual diagram of a user-desired program reconstruction method when content data registered in a user-desired program is deleted from content data in a storage medium. It is assumed that the user desired program 1303 is configured from the program list 1301 before the content data in the storage medium 1302 is deleted. Assume that the content data SC-2 is deleted from the content data in the storage medium 1302 by the user. After the content data is deleted, a large broadcast vacant time is vacated in the user-desired program, so that it becomes necessary to reconfigure. As a result of deleting content data SC-2 and reconstructing user-desired content data, a new user-desired program 1304 is reconstructed.

  The procedure of the user desired program reconstruction method when the content data in the storage medium described in FIG. 13 is deleted will be described with reference to the flowchart shown in FIG. This method assumes that user-desired content data has already been configured. In step S1401, it is determined whether the deleted content data in the storage medium is a user-desired program. If it is not a user-desired program, there is no need to reconfigure, and the user-desired program reconstruction process ends. If the deleted content data in the storage medium is a user-desired program, in step S1402, the deleted content data is deleted from the user-desired program. In step S1403, the broadcast idle time until the next real-time content is calculated, and in step S1404, the broadcast time of the content data in the storage medium is acquired. In step S1405, the broadcast free time is compared with the broadcast time of the content data in the storage medium. If there is content data in the storage medium that fits in the broadcast free time, the content data in the storage medium is converted to the content data desired by the user in step S1406. Register as On the other hand, if there is no content data in the storage medium that can be accommodated in the broadcast idle time, there is no content data in the storage medium to be incorporated in the broadcast idle time, and the user-desired program reconstruction process is terminated.

  In the reconfiguration method of user-desired content data in FIG. 14, the processing is terminated if there is no content data in the storage medium to be incorporated in the broadcast idle time, but the content data in the storage medium is the same as in FIG. Can be divided and incorporated into the broadcast idle time.

  Next, a reconfiguration method when new content data is added to the storage medium will be described. FIG. 15 is a conceptual diagram showing a configuration method in the case of reconstructing user-desired content data by adding new content data to the storage medium.

  It is assumed that the user desired program 1503 is configured from the program list 1501 before adding new content data to the storage medium 1502. A case is assumed where new storage medium content data SC-4 is added to the storage medium 1502 by the user. In the example shown in FIG. 15, the time when the content data SC-4 is added is during viewing of the real-time content RTC-1. When the content data SC-4 is added by the user, the user-desired program selection unit 1205 notified of the addition of new content data by the storage medium change notification unit 1209 causes the user-desired content after the added time. Reconstruct the data. As a result of the reconfiguration, the user desired program is updated to a new user desired program 1504.

  A procedure of a method of reconfiguring content data desired by the user when new content data is added to the storage medium 1502 described in FIG. 15 will be described with reference to the flowchart shown in FIG. In this method, it is assumed that the content data desired by the user has already been configured, as in the flowchart shown in FIG. In step S1601, the priority of the content data is set from the program information of the newly added content data, and other content data in the storage medium registered in the user desired program 1503 is deleted from the user desired program. In step S1602, it is determined whether all currently acquired program information has been searched. If all program information has been searched, the reconstruction process is terminated. If there is any program information that has not been searched yet, the broadcast idle time until the next real-time content is calculated in step S1603, and the priority order is searched from the program information in the storage medium in step S1604. In step S1605, the broadcast idle time is compared with the broadcast time of the content data in the storage medium. If there is content data that can be accommodated in the broadcast idle time, the content data in the storage medium is set as user-desired content data in step S1606. register. On the other hand, if there is no content data that can be accommodated in the broadcast idle time, there is no content data in the storage medium to be incorporated in the broadcast idle time, and the process returns to step S1602.

  In the flowchart of FIG. 16, when there is no content data in the storage medium that can be accommodated in the broadcast idle time, the process moves to the process of incorporation in the next broadcast idle time. However, as shown in FIG. By delaying the time, the content data in the storage medium is divided in order to incorporate the content data in the storage medium into the broadcast idle time as shown in FIG. It is also possible to use the method.
