Description

  The present invention relates to a broadcast receiving apparatus that supports program viewing reservations and recording reservations using program CMs.

In recent years, digitalization of broadcasting has progressed, and when a user makes a recording reservation for a broadcast program, it is often performed using an EPG (Electronic Program Guide).
In addition, when viewing a broadcast program, the user selects an interested program from programs being broadcast by zapping, or confirms a program being broadcast by EPG, selects a program of interest, and views the program. Or viewing reservations or recording reservations.

  Moreover, there is a CM for a program (commercial) as one of the chances that the user is interested in a broadcast program. This is a CM for a program preview that flows in the same manner as a commercial CM of a program sponsor that flows in a broadcast program (also referred to as a main program) being viewed, or a CM for a program preview that flows between main programs.

  When a user decides to watch or record by watching a CM for a program, the program stores the information on the program he / she is interested in, that is, the broadcast channel, broadcast date / time, program name, etc., and searches for the corresponding program from the EPG, Viewing reservations or recording reservations must be made.

In order to save the user's trouble as described above, the techniques of Patent Documents 1 to 3 are disclosed.
Patent Document 1 broadcasts reservation control information in association with a CM for a program, and when the program CM is displayed, the reservation control information is displayed together with the reservation from the user so that a reservation can be made easily. I have to.

  Further, Patent Document 2 stores text information automatically extracted from a television signal for each unit period as a program information block together with a broadcast time while a program is being broadcast, and is being viewed on a television screen. When a reservation instruction is received from a user who has met a CM for a program to be reserved, the reserved program information is extracted from the information block in the program in the past predetermined time zone based on the reception time, and according to the extracted reserved program information The program is automatically reserved.

  Patent Document 3 has a table in which CMs (commercial CMs, program CMs, etc.) broadcasted in a broadcast program are associated with the broadcast time, and a user reservation is made when the program CM is broadcast. When the designation is accepted, the CM corresponding to the time at which the reservation designation is made is identified with reference to this table, the program information for this CM is acquired, and the recording reservation is made.

  By the way, since most of the commercials for programs are short in broadcast time like other commercials, the user recognizes that they are commercials for commercials and determines that they are interested. There may be a shortage of broadcast time when making a reservation.

For example, in the techniques described in Patent Documents 1 to 3 described above, it is necessary for the user to complete a reservation operation while the program CM is being broadcast. If broadcasting progresses in the state of the reservation screen of the held program, there is a risk of hindering the main program broadcast and the viewing of the next CM.
Or, there is a possibility that the reservation for the next program CM will be made, and a reservation different from the program that the user is interested in may be made.
Furthermore, in Patent Document 3, it is necessary to prepare a database for specifying program CMs and program information.

  The present invention has been made in consideration of the above-described circumstances, and even after the broadcast of the program CM is finished, the broadcast reception can be used to easily make a viewing reservation or a recording reservation by using the program information of the program CM. An object is to provide an apparatus.

  In order to solve the above-described problems, the broadcast receiving apparatus of the present invention extracts a program CM in a program broadcast on a selected channel, and broadcasts at least a program scheduled to be broadcast advertised in the program CM. A program information extracting unit for extracting a channel, program name, and broadcast date and time as program information; a program information accumulating unit for uniquely accumulating the program information; accumulating the extracted program information in the program information accumulating unit and the program A program information management unit that updates information, displays a list of program information stored in the program information storage unit and outputs the program information selected for reservation by a user operation, and the reservation selected A reservation management unit for reserving a program based on the input of the program information.

  The program information extraction unit (1) extracts the program information from the metadata assigned to the program CM, or (2) program information from video data of a program broadcast on the selected channel. A CM is extracted, and the program information is extracted by analyzing character information and / or audio information of audio data included in the video data of the program CM.

Further, the program information management unit updates the program information storage unit as follows.
(1) When a program is reserved by the reservation management unit, reserved information is added to the program information of the program to update the program information storage unit.
(2) Monitoring whether a predetermined time has elapsed from the date of accumulation of the program information accumulated in the program information accumulation unit, and deleting the updated program information from the program information accumulation unit for updating.
(3) Monitor whether the scheduled broadcast date of the program indicated by the program information stored in the program information storage unit has elapsed, and delete the updated program information from the program information storage unit and update it.

  Further, the program information management unit, when the program information extracted by the program information extraction unit is already provided with reserved information and stored in the program information storage unit, is combined with the CM for the program being broadcast. The reserved information is displayed.

  According to the present invention, since information related to a program to be broadcast in the future extracted from a broadcast program being viewed is held and managed, the user can easily make a viewing reservation or a recording reservation even after the program CM is finished.

  In addition, when a program CM of a program that has already been reserved for viewing or recording is broadcast, information indicating that this CM for viewing has been reserved for viewing or reserved for recording is displayed. There is no need to make a reservation for viewing or recording a program, so that the trouble of confirming the reservation is saved and the convenience is improved.

  Embodiments of the present invention will be described below with reference to the drawings.

<Embodiment 1>
FIG. 1 is a block diagram showing a configuration of a broadcast receiving apparatus according to Embodiment 1 of the present invention.
In FIG. 1, a broadcast receiving apparatus 1 includes a broadcast receiving unit 101, a program information extracting unit 102, a program information managing unit 103, a program information accumulating unit 104, an information acquiring unit 105, a user input unit 106, a reservation information generating unit 107, a control. A display unit 109, a display unit 109, and a viewing / recording reservation management unit 110.
In addition, a recording / reproducing apparatus 2 may be externally connected to the broadcast receiving apparatus 1.

First, an outline of the operation of the broadcast receiving apparatus 1 will be described.
The broadcast receiving apparatus 1 extracts a program CM from broadcast data of a selected broadcast channel, and extracts program information (program name, broadcast channel, broadcast date, etc.) from metadata added to the program CM. This is stored in the program information storage unit 104.
The program information storage unit 104 stores the extracted program information in the storage order in which the latest program information is first extracted (hereinafter referred to as the priority storage order), and the program that has already passed the broadcast date or time or a predetermined time. The program information of the program that has passed is maintained so as to be deleted.

The broadcast receiving apparatus 1 reads out the program information of the program CM from the program information storage unit 104 at an arbitrary timing after the end of the program CM broadcast or a user instruction, and determines whether to make a viewing reservation or a recording reservation. A list to be specified is displayed on the display unit 109.
Then, the broadcast receiving apparatus 1 executes a viewing reservation or a recording reservation for a program designated by the user with respect to the viewing / recording reservation management unit 110 or an externally connected recording / playback apparatus.
Hereinafter, each component of the broadcast receiving apparatus 1 will be described.

The control unit 108 performs overall control of the broadcast receiving apparatus 1.
For example, video data from the broadcast receiving unit 101 and display requests from each unit are displayed on the display unit 109, or a broadcast channel change request is received by the user input unit 106 and extracted to the broadcast receiving unit 101. Or the reservation information generation unit 107 is operated in response to a program information list display request stored in the program information storage unit 104.

  The user input unit 106 is connected to the broadcast receiving apparatus 1 by infrared rays, wireless communication, or the like, receives an input from the user, and outputs it to the control unit 108.

  The display unit 109 displays video data received by the broadcast receiving unit 101, contents instructed by the user input unit 106, program information for viewing reservation or recording reservation, and the like in accordance with a control signal from the control unit 108. .

  In recent TVs, as one of the functions, a viewing reservation function using a program reservation table, an HDD (Hard Disk Drive), a Blu-ray Disc, a DVD (Digital Versatile Disk), etc. are provided on the TV itself, and there is no external recording device. Thus, it is possible to make reservations for viewing and recording programs.

The viewing / recording reservation management unit 110 manages the viewing reservation information and the recording reservation information in the broadcast receiving apparatus 1, and responds to the inquiry of the viewing reservation / recording reservation information and executes the reservation.
The viewing reservation information managed here is designated if the broadcast receiving device 1 is turned on at the designated date and time to display a program of the designated broadcast channel or if the power is already on. This is information such as a program name, a broadcast channel, and a broadcast start date and time for changing the channel to the broadcast channel.
On the other hand, the recording reservation information is used when the broadcast receiving apparatus 1 has a recording function, and program information (program name, broadcast channel, broadcast start date and time, etc.) for recording the broadcast of the designated channel at the designated date and time. ).

In order to register viewing reservation / recording reservation information in the viewing / recording reservation management unit 110, a method in which a user directly uses a viewing reservation function or a recording reservation function of the broadcast receiving apparatus 1 to make a viewing reservation or recording reservation, There is a method for making a viewing reservation or a recording reservation using the program information of the program CM described in the embodiment.
In the case of viewing reservation or recording reservation according to the present embodiment, the program information to be reserved and the reservation method are received from the reservation information generation unit 107 and registration is executed.
Also, the viewing / recording reservation management unit 110 returns the managed viewing reservation information and recording reservation information in response to the viewing reservation and recording reservation inquiry from the information acquisition unit 105.

  Further, in order to connect the recording / reproducing apparatus 2 such as an HDD recorder to the outside of the broadcast receiving apparatus 1, it is possible to link devices using CEC (Consumer Electronics Control) of HDMI (High-Definition Multimedia Interface). it can. This HDMI-CEC has Timer Programming, and this function can transmit reservation information from a tuner to a recorder connected via HDMI.

Therefore, the recording reservation can be performed by sending the program information for reservation generated by the reservation information generating unit 107 to the recording / reproducing apparatus 2 via the HDMI-CEC.
In addition, recording reservation information can be obtained by the information acquisition unit 105 by sending an inquiry about recording reservation information registered in the recording / reproducing apparatus 2 to the recording / reproducing apparatus 2 via the HDMI-CEC.
Hereinafter, the viewing / recording reservation management unit 110 and the recording / playback apparatus 2 may be collectively referred to as a reservation management unit.

  In response to a request from the program information management unit 103, the information acquisition unit 105 receives viewing reservation information managed by the viewing / recording reservation management unit 110 or the recording / playback device 2 connected to the broadcast receiving device 1. Acquire recording reservation information and send back the acquired data.

The broadcast receiving unit 101 receives a broadcast wave transmitted from a broadcast station, extracts broadcast data of the channel selected by the control unit 108, and separates the extracted broadcast data into video data and non-video data. The separated video data and non-video data are output to the program information extraction unit 102 and the control unit 108.
The video data includes audio data. Further, the non-video data includes channel information, information related to a currently broadcast program, broadcast scheduled program information for generating and displaying an EPG, and the like.

Broadcast information broadcast from a broadcast station is given program information metadata related to a program, for example, a program name, a broadcast channel, a broadcast date, a broadcast time, a performer, a synopsis, and the like described in XML format. Furthermore, other information, for example, the category (genre) of the program, link information (URL or URI) to the official homepage, and the like may be included.
In the present embodiment, it is assumed that the commercial CMs such as products and services broadcasted together with the main program and the program CMs for notifying the broadcast are also provided with metadata relating to the respective CMs.

  FIG. 2 is an example of data when the main program and CM are broadcast with the respective metadata added, main part A and main part B represent the video data of main program A, and CM1 to CM5 are CM videos. It shall represent data. The program A is broadcast in order from the CM 1 shown in FIG.

  Metadata 201 is assigned to the main program A, and metadata 202, 203, etc. are assigned to CM3 and CM4, respectively. In FIG. 2, only CM3 and CM4 are illustrated as metadata regarding CMs, but metadata is also assigned to other CMs, that is, CM1, CM2, and CM5.

The metadata 202 and 203 related to the CM is given a CM identifier indicating whether the data included in the main broadcast is a commercial CM or a program CM.
The metadata 202 is assigned a CM identifier “PRENOTICE” indicating that it is a CM for a program, and similarly, the metadata 203 is assigned a CM identifier “SPONSORED”, which is a commercial CM.

  The program information extraction unit 102 monitors the video data and the non-video data separated by the broadcast receiving unit 101, and the program metadata that the program CM foretells from the program CM (hereinafter referred to as program CM metadata). For example, channel information, date and time, program name, and the like are extracted, and the extracted program CM metadata is output to the program information management unit 103.

  For example, in FIG. 2, if the CM identifier of the metadata related to the CM is “PRENOTICE”, it is sent as program CM metadata to the program information management unit 103, and if the CM identifier is “SPONSORED”, it is assumed that the commercial CM. do nothing.

When the broadcast information is received, the program information management unit 103 stores the program CM metadata extracted by the program information extraction unit 102 in the program information storage unit 104 in the order of the broadcast date and time.
The data stored in the program information storage unit 104 includes at least the following items.

CM broadcast time: Date and time when program CM was broadcast, and is a data item added when program CM metadata is stored.
Program name: The name of a program to be notified by the program CM, which is an item of program CM metadata.
Channel: A broadcast channel for a program to be notified by the program CM, and is an item of program CM metadata.
Program broadcast date and time: The broadcast date of the program to be notified by the program CM, and is an item of program CM metadata.
Program start time: The broadcast start time of a program for which the program CM gives notice, and is an item of program CM metadata.
Program end time: This is the broadcast end time of the program for which the program CM is notified, and is an item of program CM metadata.
Reservation presence / absence: information indicating whether or not a reservation has already been made when the program CM is broadcast, and reservation information is generated when the program CM metadata is stored or by the reservation information generation unit 107 It is an item that is sometimes added. This information may be a distinction as to whether or not a reservation has been made, or may be a distinction between no reservation, viewing reservation or recording reservation.

When a program information list display request is generated from the user, the program CM metadata stored in the program information storage unit 104 is acquired.
Further, the program information management unit 103 complements and adds the program information of the program CM metadata stored in the program information storage unit 104, and deletes the program CM metadata after a certain period or broadcast time has elapsed.

The following two types of data can be given to complement the program information in the CM metadata for programs.
(1) Complementation of information lacking in the extracted program CM metadata:
For example, when the program CM metadata lacks the broadcast end time, the program indicated by the program CM metadata is identified with reference to the EPG, and the broadcast end time is acquired and complemented. Further, not only the broadcast end time but also information such as performers and program outlines may be supplemented.

(2) Supplementing existing reservation information specified by the user:
Viewing reservation information or recording reservation information is acquired from a broadcast receiving apparatus or recording apparatus that has made a viewing reservation or recording reservation using the present invention or a normal EPG, etc., and the extracted program CM metadata is used as a reservation method. The corresponding information (viewing reservation or recording reservation) is given.
Furthermore, when the reservation information generating unit 107 registers the reservation information in the viewing / recording reservation management unit 110 or the recording / playback apparatus 2 connected to the broadcast receiving apparatus 1, the program information of the registered program is notified. Information corresponding to the reservation method (viewing reservation or recording reservation) is assigned to the program CM metadata for the program information.
Thus, since the reservation method (viewing reservation or recording reservation) is given to the existing program information and stored in the program information storage unit 104, the reservation information can be presented to the user.

Next, a storage example of the program information accumulation unit 104 will be described with reference to FIGS. 2 and 3.
The metadata indicated by the row 301 corresponds to the program CM metadata 203 shown in FIG. The metadata in the row 302 is a program CM broadcast at a time after CM4 indicated by the program CM metadata 203 in FIG. 2, and the metadata in the row 303 is the program CM metadata in FIG. This is a program CM broadcast at a time before CM4 indicated by 203. As described above, the metadata accumulated in the program information accumulation unit 104 is stored in the priority accumulation order.

  In addition, since the same program CM may be broadcast a plurality of times in the program information management unit 103, it is determined whether or not the same program data exists in the accumulated data when the program CM metadata is added. Check. This determination is the same when the information such as the broadcast channel, the scheduled broadcast time (broadcast date, broadcast start time, broadcast end time), program name, etc. of the program CM metadata match.

When the same program CM metadata is confirmed, the data with the old program CM broadcast time is deleted, and the CM broadcast time is updated with the new program CM metadata.
For example, when the program content storage unit 104 stores the content shown in FIG. 3 and the program CM shown in the row 301 is broadcast again at “19:29:30 on April 1, 2009” It is updated to the metadata state shown in the row 401 in FIG.

Further, the program information management unit 103 checks whether the program indicated by the extracted program CM metadata has already been reserved for viewing or recording by the user.
The confirmation of the reservation information matches the broadcast channel, the scheduled broadcast time, the program name, etc. included in the extracted program CM metadata with the viewing reservation or recording reservation information acquired by the information acquisition unit 105.
If it is determined that the data is the same, it is determined that the extracted program CM metadata is reserved for viewing or recording, and as shown in the column 501 in FIG. A reservation method (viewing reservation or recording reservation) is assigned to the data and stored in the program information storage unit 104.
Similarly, when a viewing reservation or recording reservation is made in the viewing / recording reservation management unit 110, a reservation method (viewing reservation or recording reservation) is assigned to the corresponding CM CM metadata, and the program is recorded. The information storage unit 104 is updated.

Also, when adding / updating program CM metadata, the program information management unit 103 compares the broadcast date and time with the current time for each of the program CM metadata stored in the program information storage unit 104, Delete broadcasts that have passed.
Further, this deletion may be performed based on the threshold value, condition, and timing set by the control unit 108. For example, when the user changes the broadcast channel, the CM metadata for the program accumulated during the broadcast of the program that has been viewed up to now is deleted, or after the broadcast time of the main program being viewed is over, The program CM metadata accumulated during the broadcast may be deleted.

  Further, data that has passed a certain period of time from the time when program CM metadata is accumulated (that is, the time when program CM is broadcast) may be deleted. Of course, when the program CM metadata is deleted according to the above thresholds and conditions, the program CM metadata that has been reserved for viewing or recording may be left without being deleted.

  Furthermore, the program information management unit 103 stores the program information list display request at a predetermined timing, or stores the program information list display request by the user input unit 106, and stores it in the program information storage unit 104. The program CM metadata is acquired, and the acquired program CM metadata is converted into a list form and displayed on the display unit 109 as illustrated in FIG. 6 together with the video currently being broadcast via the control unit 108. indicate.

  FIG. 6 shows a list of the program CM metadata stored in the program information storage unit 104 in a reduced display of the programs currently being broadcast. In FIG. 6A, 701 is a reduced broadcast screen, 702 is a list of stored program CM metadata, and 703 is a cursor for selecting a program to be reserved for viewing / recording by the user. Yes. The reserved program can be selected by pressing a predetermined key when the cursor 703 is moved up and down by the cursor movement key of the user input unit 106 and a desired program is viewed / recorded.

  Although FIG. 6 shows an example in which the video of the program being broadcast is reduced and displayed, a list of stored CM data for the program can be presented, and the user can select viewing reservation / recording reservation. If so, the display method is not limited to this. For example, a list of program CM data may be displayed superimposed on the video of the program being broadcast, or may be displayed on a dedicated screen. Of course, the number of data to be displayed may be matched to the display area, and is not limited.

FIG. 6B is a display example in the case where information that has been reserved for viewing or recording is attached to the CM metadata for program, 704 is reserved for recording, and 705 is reserved for viewing. It shows that. By performing such display, the user can save the trouble of reconfirming whether the program is reserved.
The display method is not limited to this, and the display color and background color may be changed depending on the reservation status, or the reserved device (external It may be a recording / reproducing apparatus or a broadcast receiving apparatus main body).

In addition, viewing reservation / recording reservation information is displayed together in response to a program display request from the user. As described above, when a program CM that has already been reserved for viewing / recording is broadcast. In addition, the reserved program information may be displayed superimposed on the program CM (FIG. 6C).
FIG. 6C shows a display example of reservation information (program name, broadcast time, etc.) when a program CM that has already been reserved flows, reservation information 706 is displayed at the bottom of the screen, and the top right of the screen is displayed. Reserved information 707 is displayed.
Note that the display position of the reservation information or reserved information is not limited to this position. For example, the program video being broadcast may be analyzed and displayed at a position that does not overlap with the program name or broadcast time. . In addition, reservation information and reserved information may be displayed in a transparent color so that the program CM being broadcast is not hidden. In addition, the reserved information may be presented with symbols or the like instead of characters.

Next, the processing procedure of the program information management unit 103 that stores program CM metadata will be described with reference to the flowchart of FIG.
First, the broadcast data selected by the control unit 108 is extracted from the broadcast wave received by the broadcast receiving unit 101, and the program information extracting unit 102 refers to the metadata attached to the extracted broadcast data to program When it is determined that the commercial CM is used, this metadata is output to the program information management unit 103 as commercial CM metadata.

  Next, the program information management unit 103 receives the program CM metadata (step S601), checks whether or not the acquired program CM metadata is stored in the program information storage unit 104, and has not been stored. If so (NO in step S602), it is confirmed whether there is a matching program CM metadata in the viewing reservation or recording reservation program obtained via the information acquisition unit 105 (step S603).

If the acquired program CM metadata has already been reserved for viewing or recording (YES in step S603), information on the reservation method is added to the program CM metadata (step S604), and this program CM metadata is set. Are stored in the program information storage unit 104 in the priority storage order (step S605).
On the other hand, if no viewing reservation or recording reservation is made (NO in step S603), the acquired program CM metadata is displayed in the priority storage order without providing viewing reservation or recording reservation information. The information is stored in the information storage unit 104 (step S605).

  On the other hand, if the acquired program CM metadata is stored in the program information storage unit 104 (YES in step S602), the broadcast time of the program CM metadata stored in the program information storage unit 104 is changed. Update to be in the priority storage order (step S606).

  Next, when viewing reservation / recording reservation completed information is added to the program CM metadata stored or updated in step S605 or S606 (YES in step S607), the fact that reservation has been made, for example, the program name and A message indicating that the broadcast date and time have already been reserved is displayed on the display unit 109 (step S608). Here, the reservation information is displayed, but a configuration in which the reservation information is not displayed may be used.

Next, the storage date and time of the program CM metadata stored in the program information storage unit 104 (that is, the broadcast date and time of the program CM) is inspected, and metadata that has passed a predetermined elapsed time from the storage date or time, or If there is metadata past the program broadcast date and time (YES in step S609), the metadata is deleted from the program information storage unit 104 (step S610), and the operation is completed.
If there is no metadata that meets the deletion condition (NO in step S609), the operation is completed without performing the deletion process.

  Here, the stored data is deleted after the reservation information is displayed. However, the reservation information may be displayed after the deletion processing is performed first, not in this order.

Next, when the program information selected from the program information management unit 103 is passed, the reservation information generation unit 107 generates reservation information from the selected program information, and receives the viewing / recording reservation management unit 110 or broadcast reception. The reservation information is output to the recording / reproducing apparatus 2 connected to the apparatus 1.
Further, reservation completion information is displayed on the display unit 109 via the control unit 108, and the program information of the reserved program and the reservation method (viewing reservation or recording reservation) are notified to the program information management unit 103. To finish the operation.
The program information management unit 103 updates the program information storage unit 104 by adding reserved information to the program CM metadata for the notified program information.

Next, a processing procedure when a user makes a viewing reservation or a recording reservation will be described with reference to the flowchart of FIG.
First, when the user makes a list display request for the stored program information using the user input unit 106, the control unit 108 sends the program information list display request to the program information management unit 103 (step S801).

  The program information management unit 103 acquires program CM metadata stored from the program information storage unit 104 (step S802), and displays a screen layout for simultaneously displaying the currently broadcast program and the acquired program CM metadata. Is created (step S803) and displayed on the display unit 109 via the control unit 108 (step S804).

  When a program to be reserved and a reservation method (viewing reservation or recording reservation) are selected by the user input unit 106 for the program information displayed on the display unit 109 (step S805), the selected program information is stored. Reservation information (program name, broadcast channel, broadcast date and time, and reservation method) are generated (step S806), and a device that performs viewing reservation or recording reservation (viewing / recording reservation management unit 110 or recording / playback apparatus 2) Reservation information is transmitted to and a reservation is registered (step S807).

  After the transmission is completed, a reservation completion message is displayed on the display unit 109 via the control unit 108 (step S808), and reserved information is added to the CM metadata for the target program (step S809) and stored. The program CM metadata is updated (step S810), and the operation ends.

  As described above, the user can make a viewing reservation or a recording reservation after the program CM is broadcast.

<Embodiment 2>
In the first embodiment described above, CM-related metadata is assigned to the CM to be broadcast, and a CM identifier for identifying whether it is a program CM or a commercial CM is assigned to this metadata.
In the second embodiment, since there is no metadata as in the first embodiment, program information is extracted from the broadcast video data to generate program CM metadata.

  Since the configuration of the broadcast receiving apparatus according to the present embodiment is the same as that of the first embodiment, the description thereof will be omitted, and the different program information extraction unit 102 and the program information management unit 103 related thereto will be described.

First, the program information extraction unit 102 will be described.
The program information extraction unit 102 determines whether the video data passed from the broadcast receiving unit 101 is a CM. If the video data is a CM, the program information extraction unit 102 analyzes character information or audio information included in the video data, and obtains program information. Extract.

  Here, the CM determination is performed based on, for example, switching timing of stereo sound and monaural sound or a change in volume level, or disclosed in Japanese Patent Laid-Open No. 2007-267211 (commercial detection method) or Japanese Patent Laid-Open No. 2003-047031. Judgment is made using a known technique described in Japanese Laid-Open Patent Publication No. 09 (Commercial Detection Method) and Japanese Laid-Open Patent Publication No. 09-219835 (Commercial Identification).

Moreover, as the character information indicating the broadcast date and time and the program name to be extracted, for example, the luminance information of the area in which the caption is displayed from the video data by a known technique described in Japanese Patent Laid-Open No. 2003-333445 (caption extraction) Then, the character area is extracted, and the character information representing the broadcast date and time is acquired by performing character recognition on the character area.
Further, for example, according to a known technique described in Japanese Patent Laid-Open No. 11-250068 (voice recognition and keyword detection), voice recognition is performed on voice data of CM in video data, and keywords are extracted. Get broadcast date and time.

  Next, if the acquired program information includes, for example, data indicating the broadcast time, the program information extraction unit 102 generates program CM metadata as the program CM, and otherwise, the program CM metadata. Does not generate data.

However, specific broadcast dates and times are not necessarily extracted. For example, relative expressions such as “Immediately after this” or “Tomorrow”, or “Weekly” when the broadcast time is fixed are used. May be used.
For example, a case where a CM for a program is displayed as shown in FIG. 9A will be described as an example. Since the screen of FIG. 9A includes the program name displayed in 901 and the broadcast date and time displayed in 902, the program name “☆☆☆☆”, broadcast date “Tomorrow”, and broadcast start The time “night 9:00” is extracted. Also, since the channel on which the current program is broadcast is “1ch”, the broadcast channel is “1ch”.
As a result, program CM metadata 903 as shown in FIG. 9B is extracted.

However, if the broadcast date / time remains in such a relative format, the specific broadcast date / time is not acquired and viewing / recording reservation cannot be made.
Therefore, the program information management unit 103 inspects the program CM metadata 903 extracted by the program information extraction unit 102 and replaces it with specific date information when relative date information is included.

For example, based on a keyword representing the current time and date, the relative broadcast date or broadcast time stored in the program CM metadata 903 is converted into a specific date and time, and the program CM metadata 903 broadcast date is converted. And replace with airtime.
That is, if the current time is “2009/04/01 Wednesday” and the broadcast date of the program CM metadata 903 is “tomorrow”, the broadcast date is replaced with “2009/04/02 Thursday” on the next day. . Also, when the broadcast date is “Every Monday”, it is replaced with “2009/04/06 Monday” which is the closest to the current time.
Also, the broadcast time “night 9:00” is replaced with “21:00”. This time is determined by whether the display form is a 12-hour system or a 24-hour system, and is determined by the setting of a device that manages reservation information.

Also, in the program information management unit 103, if there is missing data in the program CM metadata stored in the program information storage unit 104, if there is EPG data of the corresponding date and time, the calculated time information and EPG data are used. You may add / modify the program name, the broadcast end time, and the like.
For example, if tomorrow's EPG data shown in FIG. 9C has already been captured in the broadcast receiving apparatus 1, the broadcast channel “1ch”, the broadcast date “2009/04/02”, and the broadcast start time “21: 00 ”or the program name“ ☆☆☆☆ ”, the broadcast end time“ 22:30 ”is acquired, and the program CM metadata 903 is complemented as shown in FIG. Stored in the unit 104.

  Next, the processing procedure of the program information management unit 103 that complements and stores the program CM metadata will be described with reference to the flowchart of FIG. This flowchart is different in that processing steps for complementing program CM metadata are added between steps S601 and S602 of the flowchart of FIG.

  First, broadcast data selected by the control unit 108 is extracted from broadcast waves received by the broadcast receiving unit 101 and separated into video data and non-video data, and the video data from which the program information extraction unit 102 is separated is extracted. If it is determined that the program CM is a program CM, program CM metadata is generated from the program information acquired from the video data and is output to the program information management unit 103.

  The program information management unit 103 receives the CM metadata for the program, and when the broadcast time is expressed in relative terms such as “tomorrow” and “weekly”, the program information management unit 103 is concretely determined from the meaning of the term relative to the current time. It is replaced with a typical broadcast date and time (step S1001).

It is determined whether the EPG data corresponding to the acquired (or replaced) program CM metadata is available (step S1002).
This is determined based on whether EPG data is received and the EPG data includes program data indicated by “broadcast channel, broadcast date, broadcast start time”.
If EPG data is available (YES in step S1002), information (eg, broadcast end time, performers, synopsis, etc.) that is insufficient in the program CM metadata is supplemented (step S1003), and is not available (NO in step S1002), no complement is performed at this time.

  When the acquired (or replaced) program CM metadata has not been stored in the program information storage unit 104 (NO in step S1004), the viewing reservation or the recording reservation reserved obtained through the information acquisition unit 105 It is checked whether there is a matching program CM metadata in the information (step S1006).

If a viewing reservation or a recording reservation has already been made (YES in step S1006), the viewing reservation or recording reservation information is added to the program CM metadata (step S1007), and this program CM metadata is preferentially stored. The program information is stored in order in the program information storage unit 104 (step S1008).
On the other hand, if no viewing reservation or recording reservation is made (NO in step S1006), the acquired program CM metadata is displayed in the priority storage order without giving viewing reservation or recording reservation information. It accumulates in the accumulation unit 104 (step S1008).

  On the other hand, if the acquired program CM metadata is stored in the program information storage unit 104 (YES in step S1004), the broadcast time of the program CM metadata stored in the program information storage unit 104 is changed. The priority storage order is updated (step S1005).

  Next, when viewing reservation / recording reservation completed information is added to the program CM metadata stored or updated in step S1005 or S1008 (YES in step S1009), the fact that reservation has been made, for example, the program name and A message indicating that the broadcast date and time have already been reserved is displayed on the display unit 109 (step S1010). Although the reservation information is displayed here, steps S1009 and S1010 may be deleted and not displayed.

Next, the storage date and time of the program CM metadata stored in the program information storage unit 104 (that is, the broadcast date and time of the program CM) is inspected, and metadata that has passed a predetermined elapsed time from the storage date or program If there is metadata past the broadcast date and time (YES in step S1011), the metadata is deleted from the program information storage unit 104 (step S1012), and the operation is completed.
If there is no metadata that meets the deletion condition (NO in step S1011), the operation is completed without performing the deletion process.

If it is determined in step S1002 that the EPG data cannot be used, data in the program CM metadata is stored in the program information storage unit 104, but the data is updated at a timing determined by the broadcast receiving apparatus 1. May be.
That is, when the program CM metadata is acquired for the first time, even if the program indicated by the program CM metadata is not included in the EPG data, if the EPG data is updated when the broadcast date and time approaches and the EPG data is updated, Information can be acquired.
For example, when searching for a deletion target in step S1012, if the stored data includes insufficient data, the EPG includes the program indicated by the program CM metadata at the same time as searching for the deletion target. If it is included, it may be deleted.

  As described above, the user can make a viewing reservation or a recording reservation after the program CM is broadcast.
