Description

  The present invention relates to a program recording / reproducing apparatus capable of receiving a broadcast program (distributed program) that can be viewed by a large number of people, recording data of the program, and reproducing the recorded data.

  2. Description of the Related Art In recent years, video content recording / playback apparatuses using a large-capacity recording medium such as an HDD (Hard Disc Drive) have been widely used. Such a video content recording / playback apparatus is convenient for the user, such as a recording setting function based on keywords using information of an EPG (Electronic Program Guide) including a program distribution schedule and a simple program description. It has various functions to improve performance.

  However, programs that meet the user's preferences can be recorded simply by recording programs that have been set directly for recording by the user or programs that have been set for automatic recording reservation by keyword search or the like. There is a possibility that a program that has been noticed by the public or a program that has received a great response cannot be recorded.

  For example, the audience rating can be used as a guide for grasping a program that the public has been paying attention to. The audience rating is a numerical value indicating how many people (or households) are watching the program. For example, Patent Document 1 below proposes a technique for determining the recording priority of a program to be recorded from now on using the audience rating of a program broadcast in the past.

  However, the audience rating is merely an index indicating the proportion of viewers of the program, and it is difficult to conclude that the response to the program was actually great even for a program with a high audience rating. On the other hand, even a program with a low audience rating may have a program with a large response. In addition, since events during live broadcasts cannot be predicted, events with a great response during live broadcasts are not reflected in the audience rating.

On the other hand, there is personal record information using the Internet called a blog (also called a web log). For example, in Patent Document 2 below, keywords described in an article (blog content or written information) written on a blog are extracted, the keywords are ranked, and the same keyword as the keyword up to a predetermined rank is used. Has been proposed to display a program that includes the program information.

  In the conventional method using the audience rating (for example, the method using the technique disclosed in Patent Document 1), it was possible to record and view programs viewed by many people. A program with a high rate and a program with a high response are not necessarily correlated, and it is often difficult to watch a program that has become a hot topic or a program with a high response without missing it.

  Further, in a conventional method of displaying a program including a blog keyword (for example, a method using the technique disclosed in Patent Document 2), a blog including a keyword with a high ranking is not always written about the program. For this reason, there is a problem that it is not possible to accurately identify a program that has become a hot topic in the world or a program that has a great response, simply by matching a frequently used keyword with program information.

  In order to solve the above problem, the present invention obtains an echo (indicating the degree of echo that the program has become a topic of interest) indicating the magnitude of the echo of a recorded program, and views a recorded program with a high echo. It is an object of the present invention to provide a program recording / reproducing apparatus that can prompt a user.

  The user input unit 2 is an input interface for the user to perform operation settings (for example, recording settings) and operation instructions (for example, playback instructions, recording instructions, etc.) with respect to the video recording / playback apparatus 1.

  The recording setting unit 3 has a function for performing program recording setting (manual recording setting) based on an instruction from the user input unit 2 and a program recording setting (automatic recording setting) based on a keyword extracted from EPG information. Has the function to perform.

  The receiving unit 4 has a function (function such as a tuner) for receiving a broadcast program provided from the broadcast station 14. The receiving unit 4 may receive a broadcast program by receiving and processing a broadcast radio wave, or may receive a broadcast program by receiving and processing program data via a cable (cable) or the like. May be received.

  The content management unit 5 has a function of storing EPG information of a recorded program in the EPG information storage unit 9 at the time of recording, a function of causing the blog search unit 6 to search for blog information necessary for determining the degree of echo for the program, A function for causing the audience rating extraction unit 18 to acquire audience rating data necessary for correcting the echo rate, and the program selection unit 7 to determine the degree of association between each recorded program and each blog information retrieved by the blog search unit 6 A function for correcting the reverberation level for each program of the entire blog group obtained by the program selection unit 7 with the audience rating data of each program, and a priority based on the reverberation level of each program in cooperation with the program selection unit 7 It has a function for setting (priority order).

  The blog search unit 6 has a function of searching for blog information necessary for determining the degree of reverberation of a program. For example, the blog search unit 6 has a predetermined function from a broadcast time zone of a program (or when a program starts or ends). It has a function of specifying a blog updated until a time (for example, 3 hours) elapses. The blog search unit 6 may detect a blog updated at a predetermined time by inquiring of the web server 15, or may detect it by using, for example, an RSS (RDF Site Summary) format.

  Based on the EPG information of each recorded program stored in the EPG information storage unit 9, the program selection unit 7 indicates how much the blog information searched by the blog search unit 6 is related to each program. It has a function of determining the degree of association. For example, the program selection unit 7 determines each blog based on the degree of attention to the program in each blog (for example, determination based on the number of extracted keywords related to the program or the number of characters of blog content (articles described in the blog)). The degree of relevance to each program in is represented by a score, the total of the points representing the degree of relevance in each blog is calculated for each program, and the calculated total score is set as an echo for each program in the entire blog group.

  Further, the program selection unit 7 gives priority to viewing of the recorded program as compared to other recorded programs with respect to the degree of reverberation with respect to each program. It can be regarded as a program that has been attracting public attention. In this case, the video recording / reproducing apparatus 1 may notify the user to that effect (that the program is attracting public attention), for example. Note that the video recording / playback apparatus 1 notifies the user of the priority, for example, that the degree of public attention related to the program is high, or the order of higher priority (or the increase in the priority is increased). It can be used for various processes such as rearranging the order of list display in descending order. Further, a program whose degree of reverberation does not exceed a predetermined reverberation level as determined by the program selection unit 7 can be regarded as a program that has not received much attention. In this case, for example, the video recording / playback apparatus 1 lowers the priority order of a program that does not exceed a predetermined reverberation level, or lowers the image quality of the program data (program data recorded in the content recording medium 10). Alternatively, the data capacity may be reduced by deleting the program data itself.

  The program selection setting unit 8 has a function of setting so that the setting required for the determination of the echo level for each program input from the user input unit 2 is reflected in the determination of the echo level for each program by the program selection unit 7. Have. The necessary settings for determining the reverberation level for each program are, for example, how many times the blog that publishes blog content related to the program is calculated and how long the reverberation level for the program is calculated. There are various settings such as whether to target a blog, or how much reverberation (reference value) should be considered as a program that is attracting public attention. It is desirable for the user to be able to adjust these settings according to user preferences.

  The EPG information storage unit 9 has a function of storing EPG information of a recorded program recorded in the content recording medium 10. Further, the content recording medium 10 has a function of storing data of a program set for recording (recorded program).

  The read / write control unit 11 records the program data received by the receiving unit 4 on the content recording medium 10 in accordance with the recording setting of the program by the recording setting unit 3 or the content based on the reproduction instruction from the user input unit 2 It has a function of reading program data recorded in the recording medium 10.

  The data processing unit 12 has a function of performing moving image reproduction processing (for example, decoding processing) of program data read from the content recording medium 10 by the read / write control unit 11, and the display output processing unit 13 performs data processing. It has a function of converting the data processed by the unit 12 into a signal for display (and further outputting sound) on a display unit such as a monitor and outputting the signal.

  The audience rating extraction unit 18 has a function of acquiring audience rating data used for correcting the echo level when the program selection unit 7 evaluates the echo level of the program. The audience rating extraction unit 18 can acquire the audience rating of the corresponding program from an audience rating providing server (not shown) on the Internet 30, for example.

  In FIG. 2, the web server 15 includes a blog extraction unit 16, a database server 19, and a blog database 20, and is connected to the Internet 30.

  The blog extraction unit 16 has a function of extracting a blog that satisfies a predetermined condition. For example, the blog extraction unit 16 relates to a program specified by the blog search unit 6 of the video recording / playback apparatus 1 for a predetermined time (for example, 3 hours) from the broadcast time zone of the program (or when the program starts or ends). The group of blogs updated until the elapse of time is searched from the blog database 20 via the database server 19.

  The database server 19 has a function of managing the blog database 20, and the blog database 20 has a function of storing blog content written on each blog by many users who update the blog. Yes.

  Note that the video recording / reproducing apparatus 1 finally has the blog group updated until a predetermined time elapses from the broadcast time zone of a specific program (or at the start of the program or at the end of the program), What is necessary is just to be able to extract a blog in which blog content related to the specific program is posted. Functions for extracting such a blog (for example, a function for extracting a blog updated within a predetermined time, a function for determining whether or not blog content related to a specific program is posted) The video recording / playback apparatus 1 and the web server 15 may be provided, or the functions may be distributed to both the video recording / playback apparatus 1 and the web server 15.

  Here, the blog database 20 is managed by one web server 15 (one database server 19), but necessary blog information is obtained from a plurality of blog databases 20 managed by different blog managers. It is also possible to extract.

  Next, the operation of the video recording / reproducing apparatus in the first embodiment of the present invention will be described with reference to FIG. FIG. 3 is a flowchart showing an example of the operation of the video recording / playback prime manager in the first embodiment of the present invention.

  In FIG. 3, the video recording / playback apparatus 1 first uploads a group of blogs updated within a predetermined time (for example, within 3 hours from the end of broadcast of a program) on the Internet for each program being recorded or recorded. (Step S101). Then, the video recording / playback apparatus 1 blog content related to each program within a predetermined time from a group of blogs updated within a predetermined time based on, for example, EPG information or information (keywords) in the blog. Is searched (step S102).

  When searching for a blog in step S102, each blog can be scored to specify a blog having a high degree of association with the program. For example, if the program name is directly described in the blog, the blog can be determined as a blog having a considerably high degree of association with the program. Moreover, if the name of the performer is described, the degree of association with the program of the blog may be slightly high, and it may be determined that the degree of association becomes higher as a plurality of names of performers are written. Further, the degree of association between a blog and a program may be changed with the passage of time from the start of recording. For example, if a blog is updated during or immediately after recording a program, it is determined that the degree of association between the blog and the program is high, and updated after a long time has elapsed since the recording of the program ended. It may be determined that the degree of association between the blog and the program is low.

  The video recording / playback apparatus 1 calculates the total degree of relevance of each blog with respect to each scored program and sets the calculation result as the degree of reverberation for each program (step S103). If possible, the video recording / playback apparatus 1 may acquire the audience rating of each program (step S104), and correct the degree of echo for each program in consideration of the audience rating of each program (step S105). .

  For example, if the audience rating of a program is high, it is expected that there will be a large number of blogs containing blog content related to the program. to correct. That is, correction is performed in consideration of the fact that the blog content related to a program with a high audience rating becomes a topic in a large number of blogs can be expected to some extent. Conversely, even if the program has a low audience rating, if there is a large number of blog contents related to the program or posted blogs, it is considered that the program had a large response, and the degree of response to the program is relative. It is corrected to increase.

  Then, the video recording / reproducing apparatus 1 determines whether or not the reverberation degree for each program (if corrected in step S105, the reverberation degree after correction) has reached a predetermined reverberation degree (reference value). (Step S106). As for a program whose reverberation level has reached a predetermined reverberation level, the program is regarded as a program with high public reverberation, the priority of the program is raised (step S107), and the target program is noticed to the user from the public. It is notified (step S108). As a notification method in step S108, for example, when there are a plurality of programs whose priority is raised in step S107 on the same day, the user may be notified as “Yesterday's attention program” on the next day. Good.

  On the other hand, the video recording / playback apparatus 1 regards a program whose reverberation level does not reach a predetermined reverberation level as a program that has not been written to a blog for the target program and has low reverberation in the world (step) S109) In particular, the priority of this program is not raised. Note that the video recording / playback apparatus 1 may change the priority order of each program according to the degree of association and the audience rating of each program, and further, a program with a low priority order in order to save the capacity of the content recording medium 10. The image quality of the data may be reduced, or the program data itself may be deleted.

  FIG. 6 shows that a predetermined time (for example, 3 hours) has elapsed since the blog search unit 6 of the video recording / playback apparatus 1 according to the first embodiment of the present invention has finished recording a program (end of broadcasting). It is a graph which shows the search result which searched the blog group updated until now from the Web server 15. FIG.

  In FIG. 6, the blog contents related to the programs 1 to 3 were updated in 3 hours from 21:00 (program broadcast end time) to 0:00 (3 hours after the program broadcast end time). A graph shows an example of the cumulative number of blog updates. It is assumed that broadcasting of all programs 1 to 3 ended at 21:00. In FIG. 6, for any program 1 to 3, the total number of blogs (updated blog number) in which the blog content related to each program 1 to 3 is updated is from 21:00 to 0:00. It will reach 1000 cases in 3 hours.

  From the graph of FIG. 6, blog updates are concentrated for program 1 within one hour after the end of program, and program 2 is a blog with a fixed number (a constant percentage) over time after the program ends. It can be seen that blog updates are concentrated on program 3 after a while from the end of the program.

  In addition, as a feeling of the blog writing position, if the content of the program is shocking, it is considered that the blog will be written as soon as the program ends, so program 1 has a strong impact on many people It is thought that it was. Further, since program 2 is updated at a certain rate, it is considered that there was no impact as much as program 1. Program 3 had no impact, but could have been a memorable program, or a program that did not watch the program but had known and responded to reviews and news.

  The video recording / playback apparatus 1 obtains a change in the time update status of the blog as described above (for example, the relationship between the broadcast end time of the program and the number of blog updates as described above), thereby It is possible to determine the degree of reverberation. For example, according to the user's preference, a setting is made to increase the priority of only a high impact program such as program 1 or to increase the priority of only a program that has remained in mind afterwards such as program 3. May be. Here, the monitoring period of the update status of the blog is about several hours from the end of the broadcast of the program, but may be a longer period (for example, several days or weeks).

  In addition, for programs that are broadcast regularly such as daily or weekly (for example, programs such as continuous dramas), the update status of the blog related to the program is monitored for each broadcast, and the monitoring results are It is possible to obtain the degree of echo for a program and compare the degree of echo for each program.

  FIG. 7 shows a search result in which the blog search unit 6 of the video recording / playback apparatus 1 according to the first embodiment of the present invention searches the Web server 15 for a blog group updated after the recording of the same program with different broadcast times. It is a graph which shows. In addition, here, a program that is continuously broadcast regularly is continuously monitored for a predetermined period (for example, 4 weeks), and the degree of reverberation for each program is acquired from the monitoring result, and the reverberation for each program is obtained. Comparison of degrees.

  In FIG. 7, for program 1, for example, the number of blogs gradually decreases from broadcasting in the first week to broadcasting in the fourth week. This decrease in the number of blogs indicates that the response of the program has been declining moderately. This is the result of showing that everyone is paying attention to the first broadcast, but that it will become less interesting from the next week, and the normal program shows such a change in response.

  In FIG. 7, regarding the program 2, the number of blogs broadcast in the first week is large, but the number of blogs is extremely decreased after the second week. Such a program shows only a large initial response, and the overall response of the program is small. When such a comparison result is obtained, for example, the video recording / reproducing apparatus 1 lowers the priority of the program 2 recorded and stored weekly, or raises the priority of only the program of the first week and remains ( For other broadcast times, the priority may be lowered.

  In FIG. 7, program 3 is gradually increasing weekly from the number of blogs broadcast in the first week. Such a program shows a stable response. When such a comparison result is obtained, the video recording / reproducing apparatus 1 may increase the priority of the program 3 recorded and stored every week, for example.

  Note that the video recording / playback apparatus 1 corrects the reverberation for each program in consideration of changes in the blog's temporal update status as shown in FIGS. 6 and 7, for example, the steps of the flowchart of FIG. This can be performed before and after the correction based on the audience rating in S105.

  As described above, according to the first embodiment of the present invention, when the recorded program is broadcast, the update status of the blog including the description related to the recorded program in the blog group published on the Internet 30 is changed. Based on this, it is possible to calculate the general public reverberation degree (degree of attention) for this recorded program and perform processing according to the calculated reverberation degree (notification to the user or processing according to the reverberation degree). Become. In addition, the video recording / playback apparatus 1 can calculate the degree of echo for a program in the general public more accurately by acquiring the audience rating of the recorded program and correcting the degree of echo for the program with the obtained audience rating. Become.

Will not be described.

  The blog filter setting unit 17 has a function of setting blog search conditions in the blog search unit 6. The blog filter setting unit 17 sets information such as sex, age, occupation, place name, and hobbies input from the user input unit 2 as search conditions when the blog search unit 6 performs a blog search.

  When a search condition is set by the blog filter setting unit 17, the blog search unit 6 performs a blog search by narrowing down the search target according to such a search condition. As a result, the blog search unit 6 can obtain a search result including only the blog of the target layer (that is, the search condition) to be noticed. The search condition set by the blog filter setting unit 17 is, for example, the content corresponding to the profile of the user of the video recording / playback apparatus 40, so that the same conditions as the user of the video recording / playback apparatus 40 (for example, the same The reverberation degree for each program of people with age and the same gender) can be acquired.

  As in the first embodiment of the present invention described above, the blog search unit 6 passes the search results to the program selection unit 7, and the program selection unit 7 selects each program in the blog group that narrows down the search target according to the search condition. The total degree of relevance of each blog with respect to is calculated, and the calculation result is set as the degree of reverberation for each program. In addition, regarding audience rating data for correcting the degree of reverberation obtained in this way, the audience rating data classified by gender and age is used to evaluate the degree of attention to the program by the target audience that you want to focus on. May be.

  Next, the operation of the video recording / reproducing apparatus in the second embodiment of the present invention will be described with reference to FIG. FIG. 5 is a flowchart showing an example of the operation of the video recording / playback prime manager in the second embodiment of the present invention.

  In FIG. 5, first, the blog filter setting unit 17 of the video recording / playback apparatus 40 sets blog search conditions according to the input from the user input unit 2 (step S201). The blog filter setting unit 17 can set a restriction by a profile such as a blog target layer (for example, limited to men in their 20s) as a blog search condition.

  When a program is recorded, the video recording / reproducing apparatus 40 is updated within a predetermined time (for example, within 3 hours from the end of the program broadcast) for each program being recorded or recorded. Blog groups are extracted (step S202). Then, the video recording / reproducing apparatus 40, for example, blog contents related to each program within a predetermined time from a group of blogs updated within a predetermined time based on EPG information or information (keywords) in the blog. Is searched for a blog (step S203).

  Further, the video recording / reproducing apparatus 40 limits the search target blog to the search condition (male in his twenties) input in step S201 and narrows down the search results (step S204). With respect to the blog obtained as a result, The total relevance of each blog with respect to the program is calculated, and the calculation result is set as an echo for each program (step S205). If possible, the video recording / reproducing apparatus 40 may acquire the audience rating of each program (step S206), and correct the degree of echo for each program in consideration of the audience rating of each program (step S207). .

  Then, the video recording / reproducing apparatus 40 determines whether or not the reverberation degree for each program (if corrected in step S207, the reverberation degree after correction) has reached a predetermined reverberation degree (reference value). (Step S208). For a program whose reverberation level has reached a predetermined reverberation level, the program is regarded as a program with a high level of reverberation, and the priority of the program is increased (step S209), and the target program is attracting attention from the public. It is notified (step S210). As a notification method in step S210, for example, when there are a plurality of programs whose priorities are increased in step S209 on the same day, the user may be notified as “Yesterday's attention program” on the next day. Good. In step S210, the user may be notified of a predetermined number of recorded programs in order from the recorded program with the highest priority.

  On the other hand, the video recording / reproducing apparatus 40 regards a program whose reverberation level does not reach a predetermined reverberation level as a program that does not have much blog writing for the target program and has low reverberation in the world (step). S211), in particular, the priority of this program is not raised. Note that the video recording / playback apparatus 1 may change the priority order of each program according to the degree of association and the audience rating of each program, and further, a program with a low priority order in order to save the capacity of the content recording medium 10. The image quality of the data may be reduced, or the program data itself may be deleted.

  Note that, in the second embodiment of the present invention, as in the first embodiment of the present invention described above, the degree of echo for each program may be determined in consideration of the update status of the blog.
