  According to the present invention, it is possible to acquire the public interest level of a broadcast program and contribute to the convenience of the user in selecting a program.

  A digital broadcast receiver according to an embodiment of the present invention will be described below with reference to FIGS.

  FIG. 1 shows an HDD recorder 30 with a terrestrial digital tuner (further, a DVD player 22 is added) 30. The antenna 1 receives a terrestrial digital broadcast signal sent from a terrestrial broadcast station.

  The terrestrial digital tuner 2 takes out a signal of a specific frequency from the high frequency digital modulation signal including the video / audio data. Further, the tuner 2 includes a demodulation circuit, a deinterleave circuit, an error correction circuit, and the like, thereby demodulating the selected digital modulation signal and outputting a transport stream.

  An MPEG-TS decoder separation circuit (hereinafter simply referred to as a decoder) 3 converts the transport stream into an MPEG2 (Moving Picture Experts Group 2) video stream, an audio stream, and PSI / SI (Program Specific Information / Service Information). To separate. The AV decoder unit includes a video decoder that decodes a video stream and an audio decoder that decodes an audio stream. Video data output from the video decoder is output to the video processing unit 4, and audio data output from the audio decoder is output to the audio processing unit 5. The PSI / SI includes program information (title, start time, duration, genre information, program content details, etc.) indicating what kind of program each program is. The CPU 13 displays an electronic program guide (EPG) freely designed on each receiving device side on the screen by using an OSD (on-screen display) function and the program information.

  The video processing unit 4 receives the video data of the received video, performs D / A conversion and down-decoding processing, and outputs, for example, a composite video signal. The video processing unit 4 has the OSD function, and synthesizes video based on character information and color information instructed to be output from the CPU 13 with the video data. The audio processing unit 5 receives the audio data output from the decoder 3 and generates right (R) sound data and left (L) sound data.

  The video signal is supplied to the video output unit 11 through the amplifier 7. The audio data is converted into an analog signal through the D / A conversion amplifier 8 and input to the audio output unit 12. A display and a speaker (not shown) are connected to the video output unit 11 and the audio output unit 12 via an AV output terminal (not shown).

  The memory (RAM, EEPROM, flash memory, ROM, etc.) 14 stores various programs and data. For example, application programs and various data are stored in the ROM. When the power of the recorder 30 is turned on, the CPU 13 expands the program and data stored in the ROM to the RAM and executes the program on the RAM. This program includes a driver and a protocol stack for controlling the HDD 17, USB interface 20, and LAN interface 18.

  The remote control transmitter 15 is a transmitter for sending commands to the recorder 30. When a key provided on the remote control transmitter 15 is operated, signal light (remote control signal) indicating a command corresponding to the key is transmitted from a light emitting unit (not shown). The light receiving unit 16 receives the signal light output when the key of the remote control transmitter 15 is operated, converts it into an electrical signal, performs code analysis, and provides the CPU 13 with channel number information and the like.

  A LAN card 19 can be attached to the LAN interface 18. By installing the LAN card 19, an Internet connection environment can be created. The memory 14 or the LAN card 19 includes a server 50 (the server 50 is a search site (search engine providing resource), a ranking site (ranking information providing resource), a site that provides public interest level information of each broadcast program, etc.) A certain installation address (URL) is stored. The CPU 13 activates the LAN interface 18 and accesses the server 50 using the URL when, for example, receiving an instruction from the user or when a predetermined daily date and time is reached. For data communication, for example, based on TCP / IP, FTP (File Transfer Protocol) or HTTP (Hyper Text Transfer Protocol) can be used.

  In addition to performing overall control of the recorder 30, the CPU 13 executes the following processing as processing according to the present invention.

(1) Generation of Public Interest Level of Broadcast Program Using Search Site Using the LAN interface 18 and the LAN card 19, the CPU 13 accesses the search site using the URL and sends a search word. An example of processing contents is shown in the flowchart of FIG. CPU13 extracts the program title used as the said search word from the program information of each broadcast program (step S1). Next, the CPU 13 selects a search site (search engine) (step S2). Search sites (search engines) include, for example, Google, Yahoo, Google, Infoseek, excite, etc. (all are trademarks). The user may select a search site in advance.

  Next, the CPU 13 performs URL encoding processing (step S3). Note that the character code differs depending on the type of search engine (Yahoo, Goo, Infoseek is EUC-JP, and Google, excite is UTF-8 (8-bit UCS Transformation format)). Next, the CPU 13 issues an HTTP Get request packet (step S4). For example, when the search engine is Google and the search word is “project Y”, a request “GET http://www.google.co.jp/search?hl=ja&q=project Y” is issued. Then, the CPU 13 acquires an HTTP Get response packet (step S5). And from this response, CPU13 acquires the number of hits (step S6). For example, if the search engine is Google, “**” in “Swrnum = **” is acquired.

  For example, the CPU 13 performs the hit count acquisition process described above for each program title in the currently held program information. As a result, a numerical value indicating the number of hits for the title of each program can be acquired.

  Based on the above numerical value (number of hits), the CPU 13 considers the broadcast program to have a higher public interest level as the numerical value increases, and generates public interest level information of each broadcast program consisting of numerical values. As an example, if the public interest level is scored in four stages, such as 100 points, 60 points, 30 points, and 0 points, the number of hits is more than 10,000 with 100 points and less than 10,000 with over 5,000 cases 60 points, less than 5,000 cases, 1000 points or more 30 points, less than 1,000 points 0 points. When the public interest level is expressed in several stages as described above, public interest level information of each broadcast program including symbols can be generated based on the score (numerical value). For example, 100 points are ☆☆☆, 60 points are ☆☆, and 30 points are ☆. Of course, the interest level (numerical value) may be generated by other methods. For example, the largest number of hits may be 100, the lowest number of hits may be 0, and the number of other hits may be quantified.

  In the above example, the program title is a search word, but the present invention is not limited to this. For example, the name of the performer in the program may be used as a search word, and the degree of public interest in the program may be generated based on the search result. Moreover, it is good also as acquiring the search result by AND and OR of several words, such as a title name, a broadcast station name, and a program genre. Further, it is not limited to the HTTP protocol Get request, and is not limited to a general-purpose search engine. A protocol other than the HTTP protocol may be used.

(2) Generation of public interest level of broadcast program using ranking site The CPU 13 uses the LAN interface 18 and the LAN card 19 to access the ranking site at a URL stored in advance and search for a ranked word. To do. The ranking may be a ranking without any restriction, or may be a specific ranking such as an actress ranking or a preference ranking. An example of processing contents is shown in the flowchart of FIG. CPU13 selects a ranking site (step S11). Examples of ranking sites include Google and Google. The user may select a ranking site in advance.

  Next, the CPU 13 issues an HTTP Get request packet (step S12). Then, the CPU 13 acquires an HTTP Get response packet (step S13). And from this response, CPU13 acquires the word quoted by ranking (step S14). For example, assume that the response is as follows.

<TD class = rankreala = "90%">
<DIV class = realminirankon5>
<SPAN class = "realkey1>
<DIV>
<A
href = "http://search.goo.ne.jp/web.jsp?MT=%BC%E1%CD%B3%C8%FE%BB%D2&amp;from=recentkw&amp;PT=recentkw"> ○ Taro Yamato </A>
</ DIV>
<SPAN>
</ DIV>
</ TD>
</ TR>
.....

  In such a format, search for “PT = recentkw”, and then list the first character string between “>” and “<” (in the above example, ○ Yamataro) in the ranking. As words (hereinafter, abbreviated as RW). The above character strings are also present in other rankings. By repeating the extraction of the character string, all the character strings (words) ranked can be extracted.

  Further, the CPU 13 extracts a program keyword from the program information (step S15). For example, it is assumed that the contents of the program details are “Hideyoshi (Yamataro) and child (松田 花子), Tsurumatsu suddenly, and Nene by Nene ...”. In this case, since one word (RW) listed in the ranking exists in the program details, it is assumed that 1 point is obtained (step S16). Note that a program keyword that can be acquired from program information, such as the word, title, name of the lead actor, and broadcast station name in the program details, may be abbreviated as BW.

  If the total number of words (RW) listed in the ranking is N (RW = N) and the total number of program keywords (BW) that can be acquired from the program information is M (BW = M), the total of RW and BW In a win (N × M times), the number of matches is detected (step S17, step S18). The total number of coincidence is the number of points (step S19).

  In order to extract words that are nouns from the details of the program details, a technique called morphological analysis may be used. Further, the broadcast station side may add the program keyword in advance in the program information in order to facilitate the matching process determination on the receiving device side.

  The CPU 13 performs processing for regarding the total number of points obtained for each broadcast program as the degree of public interest of each broadcast program. That is, a broadcast program having more words in the program information that are ranked in the ranking information obtained from the ranking information providing resource as the information providing resource is regarded as a broadcast program with a higher public interest, and from a numerical value. The public interest level information of each broadcast program is generated. As an example, the total number of points can be 6 or more points A rank, less than 6 points 3 points or more B rank, less than 3 points C rank. When the public interest level is expressed in several stages as described above, public interest level information of each broadcast program including symbols can be generated based on the score. For example, A rank is ☆☆☆, B rank is ☆☆, and C rank is ☆. Of course, the interest level (numerical value) may be generated by other methods. For example, the largest total number of points may be set to 100, the lowest number of hits may be set to 0, and the number of other points may be quantified.

  In the above processing example, the ranking is not considered, but the number of points may be calculated in consideration of the ranking. For example, the word ranked first is 100 points, the word ranked second is 99 points, the word ranked 99th is 2 points, ranked below 100th There is one point in the word that is being used. In this case, the score of the word given the highest score may be regarded as the public interest level instead of the score obtained by RW and BW round robin. Moreover, you may produce | generate a public interest degree only by a ranking order.

(3) Provision of public interest level of broadcast program by ranking site itself The ranking site itself may provide the public interest level (broadcast program ranking) of the broadcast program. For example, a questionnaire asking which ranking site wants to watch most among programs scheduled to be broadcast may be constantly performed on the net, and the public interest level of the broadcast program may be generated from the answer. For example, for a broadcast program with 100 or more first responses, 100 points, less than 100 cases, 50 or more cases are 60 points, less than 50 cases are 10 points or more, 30 points, and less than 10 cases are 0 points. When the public interest level is expressed in several stages as described above, public interest level information of each broadcast program including symbols can be generated based on the score (numerical value). For example, 100 points are ☆☆☆, 60 points are ☆☆, and 30 points are ☆. Of course, the interest level (numerical value) may be generated by other methods. For example, 100 may be the one with the largest number of first responses, 0 may be the lowest, and the other first responses may be digitized. Note that the ranking site can also generate public interest level information of each broadcast program by the methods (1) and (2) described above.

  The CPU 13 uses the LAN interface 18 and the LAN card 19 to access a ranking site that provides the public interest level of the broadcast program at a URL stored in advance, and obtains public interest level information (numerical value or design) of each broadcast program. The information is acquired and stored in, for example, the memory 14 (nonvolatile memory or the like).

(4) Adjustment of program interest level and public interest level according to user's preference Just because the public interest level of a certain program is high, the user's interest level for the program is not necessarily high. On the other hand, the user may want to watch a program with a high level of public interest as much as possible. Therefore, the higher the public interest level of the program and the higher the interest level of the user, the more the program should be recommended to the user. In other words, even if the degree of public interest of a program is high, if the degree of interest of the user is low, processing for lowering the order of the program to be recommended to the user is performed.

  In order to measure the user's interest level for a certain program, a so-called user preference determination method is used. For this method itself, a conventional method may be used. For example, as a simple method, the genre of the program is listed (displayed) on the user setting screen of the receiving apparatus, and one or a plurality of genres that the user likes are selected. The CPU 13 gives “0” to the program of the selected genre, and gives “−20” to the program of the genre not selected. That is, “0” and “−20” are user interest level information of each broadcast program including numerical values. Then, the CPU 13 performs a process of subtracting the user interest level information (numerical value) of each broadcast program from the public interest level information (numerical value) of each broadcast program, so that each broadcast program consisting of the user's numerical value is obtained. Generate recommendation level information. That is, if it is a program of the genre selected by the user, the public interest level information (numerical value) becomes the recommendation level information for the broadcast program of the user as it is, and if it is a program of the genre not selected by the user, A numerical value obtained by subtracting “20” from public interest level information (numerical value) is the recommendation level information of the user regarding the broadcast program. This process corresponds to correcting (weighting) the public interest level information of each broadcast program with the user interest level information of each broadcast program. If the process corresponds to such correction (weighting), the process is not limited to the above-described subtraction process, and a process using multiplication or division may be performed.

  The method for determining the user's preference is not limited to the above-mentioned genre selection, and the user's favorite broadcast station and the time zone often viewed by the user can also be input by the user. In this case, for example, “0” is given to the program in the selected time zone, and “−10” is given to the program in the non-selected time zone. It is good also as processing combining such a time slot | zone and the said genre.

  In addition, user preference is automatically determined based on digital broadcast viewing history and digital broadcast recording history (total viewing / recording time within a predetermined period, number of channel selections, etc. for each program) instead of user input. You can also. Specifically, it can be considered that the longer the total viewing / recording time within a predetermined period and the greater the number of channel selections, the higher the user's preference for a program or broadcast station. Also in this case, the user's preference can be set as user interest level information of each broadcast program. Further, it is possible to estimate a genre, a broadcasting station, a time zone, etc. that the user likes from the viewing history of digital broadcasting and the recording history of digital broadcasting. For example, each genre of each recorded program is stored, and the total recording time or the total number of recordings can be set as the user's genre preference within a predetermined period or from the beginning. For example, “+20” is given to the top three genres, and “+10” is given to the next three genres. For a genre that has never been viewed, for example, “−20” is given.

  When the recommendation level information about the broadcast program for the user is expressed in several stages, the recommendation level information for the user of each broadcast program can be generated based on the score (numerical value) of the recommendation level. For example, 100 points are ☆☆☆, 60 points are ☆☆, and 30 points are ☆.

  In addition, when there are a plurality of users for one receiving device, a user input method on the above-described user setting screen or the like is used to obtain a preference level (user interest level information of each broadcast program) for each user. It is easy to input a user name (including a nickname) prior to this input. If the degree of preference for each user can be obtained, the degree of recommendation for each program can be generated for each user.

(5) Utilization of public interest level information of each broadcast program In the following example, utilization of public interest level information of each broadcast program is shown, but the same applies to utilization of recommendation level information about broadcast programs to the user. For example, as shown in FIGS. 3A and 3B, the CPU 13 displays a list of broadcast programs and / or an electronic program guide (EPG). Then, when performing the list display and / or the electronic program guide display, the CPU 13 displays the public interest level of each broadcast program as a numerical value or a symbol on the display column of each broadcast program (in FIG. 3, the symbol is a symbol). Is shown as an example). The list display of the broadcast program is not limited to the program currently being broadcast, and for example, if program data exists, the program may be set as a broadcast reservation program target. In addition, you may employ | adopt a color design instead of a design of *. For example, instead of ☆☆☆, the background color of the display column of the program is set to red, the background color of the display column of the program is changed to green, and the background color of the program is changed to ☆, The background color is blue, and no star means the background color of the program display column is white. Further, only for ☆☆☆, the background color of the display column of the program may be red, and the others may be white. In FIG. 3A, the display pattern of the public interest level can be selected on the EPG screen. When the “next pattern” is pressed, the display of the public interest level in the symbol display is changed to the public interest level display in the numerical display.

  As shown in FIG. 3B, the CPU 13 may display a list of broadcast programs in order of increasing public interest level (sort) to display the broadcast programs. Also good. Although the block diagram shown in FIG. 1 shows a form in which only terrestrial digital broadcasting is received, a plurality of tuners can be provided to receive BS digital broadcasting and CS digital broadcasting. In the case of such a multi-tuner configuration, broadcast programs may be displayed by rearranging each broadcast program in descending order of the public interest level for all of terrestrial digital broadcasting, BS digital broadcasting, and CS digital broadcasting. it can. For example, the remote control transmitter 15 is provided with a button such as “What to see”. When the CPU 13 detects that the user has pressed the button, the CPU 13 displays the above-described program list.

  The channel number of the currently received broadcast can be displayed in the corner of the screen using the OSD function, but the public interest level of the currently received broadcast (program) is displayed in the corner of the screen. It is good as well.

(Random channel)
The CPU 13 selects a broadcast program having the highest degree of public interest in the broadcast program from among the currently broadcasted broadcast programs and displays it on the screen. For example, a button such as “Omakase Channel” is provided on the remote control transmitter 15. When the CPU 13 detects that the user has pressed the button, the CPU 13 may execute the above-described channel selection process.

  Furthermore, the CPU 13 starts the timer at the same time as performing the above-described channel selection process, and when the set time elapses, the broadcast program having the highest degree of public interest in the broadcast program is broadcast among the broadcast programs being broadcast at that time. Select the channel and display it on the screen. Such an automatic channel selection process can be used to provide a background video at a store or a storefront. For example, the automatic channel selection process may be performed when the non-operation state of the remote control transmitter 15 continues for a certain time or longer (a warning message may be displayed on the screen at this time).

  FIG. 5 is a flowchart showing the above processing contents. For obtaining the automatic channel setting conditions performed in step S21, the CPU 13 selects, for example, the channel update interval (previously described setting time) and the target network from the contents (stored in the memory 14) set in advance on the user setting screen. It is processing. The selection of the target network is any one of terrestrial digital broadcasting, BS digital broadcasting, and CS digital broadcasting.

  In steps S22 to 25, a process of extracting a broadcast program having the highest public interest level of the broadcast program among the broadcast programs being broadcast at that time is performed. In step S26, the public interest level of the broadcast program is the highest. A process of selecting a high broadcast program and displaying a video is performed. Then, it is determined whether or not the timer output t has exceeded the channel update interval T (step S28). If it has not exceeded and an end event has not been received (NO in step S29), standby and timer update are performed (step S30), and the process returns to step S28. On the other hand, when it exceeds, it returns to step S22. The end event is received when the remote control transmitter 15 is instructed to cancel the Omakase Channel (for example, pressing the “Random Channel” button again). At this time, the Omakase Channel mode is terminated. To do.

(Graph display function)
The CPU 13 holds, in the memory 14, numerical values and symbols from the past to the present of the degree of public interest of each broadcast program. Then, the CPU 13 creates a graph (a line graph, a bar graph, etc.) using the OSD function from a numerical value from the past to the present of the public interest level regarding the broadcast program designated by the user, and displays it on the display. For example, the user presses a button such as “transition of interest” provided in the remote control transmitter 15 while viewing a certain program. CPU13 which detected this pressing performs upper and lower 2 screen division | segmentation processing, and displays the said graph which shows transition of the public interest degree of the program on the lower screen. Thereby, the user can recognize the transition of the public interest level of the program. Further, the CPU 13 can determine whether or not the public interest level of the program is on the rise from the graph or the numerical value or design that is the basis of the graph. For example, when the user selects a menu such as “present a program whose public interest level is increasing” on the menu screen, the CPU 13 displays a list of programs whose public interest level of the broadcast program is increasing. To do. Thereby, it is possible to meet a user's request to view a program whose public interest level is increasing.

  For example, when the ranking site itself provides the public interest level (broadcast program ranking) of the broadcast program, the location (URL, etc.) of the information providing resource on one or a plurality of networks related to each broadcast program is described. It is good to add. For example, if the program is a drama, it may be a drama homepage, a photo collection of the shooting site of the drama, a photo collection of performers, the hero's blog, the author's homepage, or the like. The digital broadcast receiving apparatus extracts the URL and the like from the browser document received from the ranking site. When the user does not receive the broadcast but requests a homepage display related to a program with high public interest on the menu screen, for example, the CPU 13 accesses the homepage etc. and displays the screen by the browser function.
