Description

  The present invention automatically reserves recording of rebroadcast based on program information in an apparatus capable of recording and recording information such as TV programs based on program information that can be obtained from the outside and conditions set by the user. The present invention relates to a program record storage device.

Conventionally, in order for a user to select a television broadcast program, the program column of a newspaper or a program information magazine is often viewed.
In recent years, since there is a site that provides an electronic program guide (EPG) on the Internet web, it is also possible to browse the program guide on a personal computer or the like.
In addition to program information from the Internet, an electronic program guide (EPG) can be acquired from terrestrial analog broadcast waves.

  Further, in television broadcasting, electronic program guide (EPG) information is broadcast together with the television program. Therefore, if a television receiver compatible with an electronic program guide (EPG) is used, EPG information can be extracted from the broadcast wave by remote control operation, and a program guide scheduled to be broadcast can be displayed on the TV screen based on the information. Become.

  In the above-mentioned electronic program guide, each program name, program content, performer, etc. of each program are displayed for each broadcast station channel for one week or two weeks of broadcast scheduled programs.

  On the other hand, in a recording / playback apparatus such as a DVD recorder, HDD recorder, or DVD / HDD recorder, program information such as a TV program obtained from the outside is automatically searched based on a search condition set by the user as described above. Devices that can automatically set recording reservation (this function is called automatic recording reservation function) have been developed and are becoming popular. The automatic recording reservation function searches an electronic program guide with a predetermined keyword or the like based on a search condition registered in advance and automatically reserves the searched program for recording.

  By the way, in the conventional television receiver or recording / reproducing apparatus, when there is a reception failure during the broadcasting of a program for which viewing or recording reservation has been made, a viewing or recording defect due to a poor reception radio wave condition is detected. In some cases, the program information is searched for using the program name (title) as a keyword and the program is automatically reserved for viewing or recording for recovery (see, for example, Patent Document 1).

Also, the reception level of the broadcast wave is monitored, and if there is an abnormality in the reception level, the re-broadcast of the program is searched from the EPG and automatically set to the recording reservation, or the recording state recorded first is retaken. In some cases, the best recording results are obtained by comparing the recorded recording states and deleting the worse recording state (for example, see Patent Document 2).
JP 2001-309286 A JP 2000-31323 A

  However, in Patent Document 1, it is difficult to cope with recording defects that do not depend on the poor radio wave condition, for example, the inclusion of earthquake telop, interruption of emergency broadcast, program change, and the like. On the other hand, search by program name is difficult to function when the program name is not the same at the time of rebroadcast (for example, when “rebroadcast” or the like is added to the program name).

Further, in Patent Document 2, since scheduled recording is automatically performed, it is possible to avoid recording the same program repeatedly due to re-broadcasting. However, for some reason, the recorded program is mixed with telop, interrupting emergency broadcast. If the contents differ from the expected contents due to a program change or the like, there is a problem that the abnormal contents are not noticed until the recorded contents are viewed.
In view of the above problems, the present invention automatically recognizes recording defects that do not depend on the poor radio wave condition, for example, telop mixing, emergency broadcast interruptions, program changes, and can automatically schedule rebroadcasting. It is an object of the present invention to provide a program recording / storing apparatus capable of performing recording reservation by recording a rebroadcast program without missing in automatic broadcast reservation.

  FIG. 3 is a block diagram showing a functional configuration of the program record storage apparatus according to the first embodiment of the present invention. This corresponds to the functional configuration of FIG. 1, and the same components as those in FIG.

  3 includes an automatic reservation setting unit 31, a broadcast content change / abnormality detection unit 32, an EPG update timer 33, an EPG reception unit 34, an EPG display unit 35, and a recorded data DB 27a. Automatic reservation information DB 27b, EPG DB 27c, reservation information DB 27d, recorded program information DB 27e, automatic reservation condition input means 36, manual program reservation means 37, EPG search means 38, reservation information storage means 39, Recording success / failure user setting means 40, recording instruction means 41, broadcast receiving means 42, recording means 43, program information reading means 44, program information storing means 45, information notifying means 46 for users, e-mail Transmitting means 47.

  The EPG receiving unit 34 and the program information reading unit 44 correspond to the function of the program information acquisition unit 30 in FIG. The EPG receiving means 34 receives program guide information (EPG data) for a predetermined number of days transmitted as television broadcast data or Internet Web data as shown in FIG. 2, and stores it in the EPG DB 27c. The information reading means 44 reads the program information received simultaneously with the program broadcast by the broadcast receiving means 42 and stores it in the recorded program information DB 27e.

  The broadcast receiving means 42 includes a program receiving function of a wireless / wired Internet broadcast received from the Internet in addition to a normal wireless / wired television broadcast program receiving function like the TV broadcast receiving device 11, and a program. Program information can be received along with the broadcast. The program information in the broadcast receiving means 42 includes program information transmitted in a format other than the program guide information such as an electronic program guide (EPG).

The automatic reservation condition input means 36 is a function for inputting a search condition by a user operation when performing a keyword search or the like for automatic reservation.
The recording success / failure user setting means 40 replays based on the user operation when the user desires to record the same program again, for example, when the user views the recorded program, for example, when the user recognizes that the recording has failed. This is a function for issuing a recording instruction.
The manual program reservation means 37 is a function for the user to manually make a program reservation, and selects a desired program from the program table displayed on the EPG display means 35 by moving the cursor or the like, and sets the reservation information storage means 39. Use it to make a reservation setting in the reservation information DB 27d.

  The EPG update timer 33 periodically activates the reception function of the EPG reception means 34 and gives a timing (trigger) for acquiring EPG data.

  The automatic reservation setting means 31 searches for EPG data for a predetermined number of days in the EPG DB 27c using the EPG search means 38 based on the search conditions stored in the automatic reservation information DB 27b, thereby providing program data that meets the search conditions. Is set (registered) in the reservation information DB 27d using the reservation information storage means 39.

  When the recording start time comes based on the program data reserved in the reservation information DB 27, the recording instruction unit 41 instructs the broadcast receiving unit 42 to execute recording of the reserved program. The broadcast program received by the broadcast receiving means 42 is sent to the recording means 43 and stored in the recording data DB 27a, while being sent to the program information reading means 44 to read the program information, and the program information is stored in the program information storing means. 45 is stored in the recorded program information DB 27e. In the recorded program information DB 27e, real-time program information of programs actually received by the recording reservation execution is stored, while program information obtained from the EPG data from the reservation information DB 27d is also stored and held for a certain period. It will be.

  The broadcast content change / abnormality detection means 32, when text data indicating telop, emergency broadcast, program change, etc. is inserted in the program information of the broadcast station read by the program information reading means 44, the program information storage means 45. While notifying the abnormality detection, the automatic reservation setting means 31 is also notified of the abnormality detection. As a result, the automatic reservation setting means 31 corresponds to the incomplete recording (that is, the recorded data becomes incomplete) as search information necessary to automatically reserve the rebroadcast of the current recorded program, Using all or part of the program information about the recorded program stored in the recorded program information DB 27e, the EPG DB 27c is searched every time the EPG data is updated, and there is a program that satisfies the search condition. If there is no reservation overlapping in time, the program data is set (registered) in the reservation information DB 27d as reservation information.

  By the way, if the program information is a rebroadcast program, there is a possibility that the information is small as seen in the program column of a newspaper television. The program title is shortened or has no subtitle. Then, even if it is a rebroadcast program that is the same as a program that has been reserved for recording once and recorded, for example, even if a search is performed again using only the program title, it cannot be recognized as a rebroadcast program of the same content. there is a possibility.

  Specifically, the program information of a program that has already been recorded is stored in the recorded program information DB 27e. However, not only the title of the program is entered here, but various information is recorded when recording automatically. Information such as the name of the broadcasting station, the length of the broadcasting time, the names of actors and directors appearing, etc. are also included. Therefore, when the rebroadcast is automatically searched, the EPG data periodically updated in the EPG DB 27c is searched by using all the information and using an appropriate combination of OR and AND of the information as search information. As a result, the recording reservation setting is performed again. As a result, the search can be performed with fewer omissions than when the search is performed again using only the program title. In other words, when automatically searching for a rebroadcast program and making a reservation, the reservation range is made a little wider and a recording reservation is automatically made again.

  Next, examples of information stored in the DBs 27c, 27e, 27d, and 27b in the recording device 27 are as follows.

Table 1 shows an example of general program guide information stored in the EPG DB or the like.
A device such as a personal computer with a built-in TV tuner or an HDD recorder displays program information to the user based on program guide information such as EPG, and the user can generally specify program reservation based on the displayed program information. For program reservation, information on broadcasting station, broadcasting date, broadcasting start time and broadcasting end time is required. In addition, additional information such as program summary information may be attached.

The automatic reservation information DB 27b sets information for searching and selecting a program to be reserved when automatic reservation is performed. A combination of a plurality of information can be searched. Different groups of information are set so that multiple types of broadcasts can be automatically reserved.

図４は図３における自動予約処理のフローチャートを示している。
ＥＰＧ更新タイマ３３は、一定時間毎に即ち定期的にＥＰＧ受信手段３４をトリガする。これによって、ＥＰＧ受信手段３４は、番組表情報を提供する放送局からの放送波を受信したり、或いはインターネットの番組表情報提供サイトへのアクセスを行うことによって、ＥＰＧデータの更新処理に入る（ステップＳ1）。そして、新たに取得したＥＰＧデータが更新されているか否かの判定を行う（ステップＳ2）。 [Table 4]

FIG. 4 shows a flowchart of the automatic reservation process in FIG.
The EPG update timer 33 triggers the EPG receiving means 34 at regular intervals, that is, periodically. As a result, the EPG receiving unit 34 enters an EPG data update process by receiving a broadcast wave from a broadcasting station that provides program guide information or by accessing a program guide information providing site on the Internet ( Step S1). Then, it is determined whether or not the newly acquired EPG data has been updated (step S2).

  If the acquired EPG data has been updated, the automatic reservation setting process (see FIG. 6) by the automatic reservation setting means 31 is started after updating the EPG data in the EPG DB 27c (step S4). If the acquired EPG data has not been updated in step S2, the automatic reservation setting process (see FIG. 6) is not performed.

  Alternatively, when read information (that is, program information) from the program information reading unit 44 is delivered to the broadcast content change / abnormality detection unit 32, the broadcast content change / abnormality detection unit 32 performs broadcast content change / abnormality detection processing (see FIG. 5). ) Is performed (step S5). Then, when the scheduled recording ends, the normal / abnormal end information of the recording is notified from the broadcast content change / abnormality detection means 32 to the automatic reservation setting means 31 by the broadcast content change / abnormality detection processing, so that the automatic reservation setting means 31 automatically The reservation setting process (see FIG. 6) is started (step S4).

  Alternatively, the automatic reservation setting process (see FIG. 6) by the automatic reservation setting unit 31 is also performed by the recording success / failure user setting unit 40 that is activated when the user wants to record the same program again when viewing the recorded program. It is activated (step S4).

  Upon entering the recording success / failure user setting process by the recording success / failure user setting means 40 according to the user's request (step S6), it is determined whether or not the setting made by the user at that time was a recording failure setting (step S7). If the result of determination is that recording failure has been set, the aforementioned automatic reservation setting process (see FIG. 6) is performed (step S4). If no recording failure is set in step S7, the automatic reservation setting process (see FIG. 6) is not performed.

  On the other hand, even when the user changes the automatic reservation condition by the automatic reservation condition input means 36, the automatic reservation setting process (see FIG. 6) by the automatic reservation setting means 31 is started (step S4).

FIG. 5 shows a detailed flowchart of the broadcast content change / abnormality detection processing step S5 of FIG.
In the broadcast content change / abnormality detection process by the broadcast content change / abnormality detection means 32, an update notification from the EPG update timer, a recording normal / abnormal end notification at the end of recording of the reserved program, a recording success / failure user setting notification, or automatic The program is started by a condition change notification from the reservation condition input means, the program information is received together with the program broadcast by the broadcast receiving means 42, and the text data is searched from the program information read by the program information reading means 44. Then, when a predetermined text to be inserted into the program information appears when the broadcast station sends information indicating telop, emergency broadcast interruption, program change to the text data, it is determined that there is an abnormality, and that is notified to the automatic reservation setting means 31. To do. On the other hand, if the text is not detected until the end of recording, the automatic reservation setting means 31 is notified of the normal end of recording. This process will be described with reference to FIG.

  In FIG. 5, when the program information read by the program information reading means 44 is delivered to the broadcast content change / abnormality detection means 32, the broadcast content change / abnormality detection means 32 first adds a telop to the program information as follows. Then, it is confirmed whether text (keyword) to be inserted into the program information appears when information indicating emergency broadcast interruption or program change is flowed (step S41). The keywords include "Earthquake Early Warning", "Earthquake Warning", "Emergency Broadcast", "Emergency News", "Disaster Information", "Tsunami Warning", "Change Program", and "Change Program".

  Then, it is determined whether or not the keyword as described above is included in the program information (step S42). If the keyword is included, the program information storage means 45 is notified of abnormality detection (step S43), while the automatic reservation setting means 31 is notified of abnormality detection (step S44).

  If no keyword is included in step S42, it is determined whether or not the recording has ended (step S45). If the recording has not ended, the process returns to step S41.

  If the recording is completed in step S45, the automatic reservation setting means 31 is notified of the normal end (step S46).

FIG. 6 shows a detailed flowchart of the automatic reservation setting process step S4 of FIG.
When the recording abnormality is notified, the automatic reservation setting means 31 reads the search information and program information used for searching for the program from the recorded program information DB 27e, and sets the search conditions in the automatic reservation information DB 27b as a search condition. Make a reservation. However, if the same search condition already exists in the automatic reservation information DB 27b, it is not added.

  When the normal recording end is notified, the automatic reservation setting means 31 is an automatic reservation in order to prevent the program from being duplicately recorded since the program is a one-time recording program unless the setting of repeated recording is made. The title of the program is added as exclusive information to the search information in the information DB 27b. As a result, duplicate recording is avoided and the storage area of the recording device 27 is not wasted.

  When an update notification indicating that the EPG has been updated is notified, when a recording abnormality is notified, or when normal recording end is notified and the automatic reservation information DB 27b is changed, the automatic reservation setting means 31 automatically updates the automatic reservation information. Based on the search conditions of the DB 27b, the EPG search means 38 is used to search the EPG DB 27c, and if a corresponding program exists, information required for program reservation is registered in the reservation information DB 27d. If a program reservation overlapping with the program reservation is already registered in the reservation information DB 27d, the display device 15 and / or e-mail transmission of the program record storage device 1 using the information notification means 46 to the user is used. The means 47 notifies the user of the duplication. This allows the user to select which of the old and new program reservations is really good. If the user does not make adjustments separately by the program reservation selection process, for example, the previously reserved program is preferentially reserved for recording. This process will be described with reference to FIG.

  In FIG. 6, when there is a recording abnormality notification, a recording normal end notification, or an EPG update notification from the automatic reservation setting means 31, it is first determined whether or not there is an EPG change notification (step S51).

  If there is an EPG change notification, the automatic reservation setting means 31 searches the EPG DB 27c using the EPG search means 38 based on the search conditions of the automatic reservation information DB 27b (step S56), and whether there is a corresponding program. It is determined whether or not (step S60).

  If there is a corresponding program, it is searched whether there is a reservation with overlapping time in the reservation information DB 27d (step S61), and it is determined whether there is a reservation with overlapping time (step S62). If a program reservation that overlaps with the program reservation has already been registered in the reservation information DB 27d, the display device 15 and / or e-mail transmission means 47 of the program record storage device 1 using the information notification means 46 to the user is used. To notify the user of the duplication (step S63).

  At this time, the user separately selects one of the old and new program reservations of the program reservation, and registers it as reservation information of the program in the reservation information DB 27d (step S64). If the user does not make any adjustment by the program reservation selection process, the previously reserved program is preferentially registered for recording reservation. In step S62, if there is no reservation with overlapping time, the reservation information of the newly reserved program is registered (step S64).

  On the other hand, if there is no EPG change notification in step S51, it is determined whether or not the recording is abnormal (step S52). Whether or not the recording is abnormal is determined based on whether or not the program information includes text data (keywords) indicating a telop inserted at the broadcasting station, an emergency broadcast interruption, and a program change as shown in FIG. .

  If it is determined in step S52 that the recording is abnormal, the program search information necessary for automatic rebroadcasting of the program is read from the recorded program information DB 27e (step S53), and the same conditions as those used for searching the program are obtained. It is determined whether or not it exists in the automatic reservation information DB 27b (step S54). If the same condition is not found in the automatic reservation information DB 27b, the program search information is set in the automatic reservation information DB 27b (step S55), and the process proceeds to the steps after step S56 described above.

  If the automatic reservation information DB 27b has the same conditions used for searching for the program in step S54, the program proceeds to the steps after step S56 without adding the program search information.

  On the other hand, if there is no recording abnormality in step S52, that is, if the recording is normal, the reservation information of the corresponding program is read from the reservation information DB 27d (step S57), and whether or not the repeated reservation is set. Determination is made (step S58). If the repeated reservation is set, for example, if it is a continuous drama, it must be reserved several times under the same search condition, so the process proceeds to a repeated reservation process (not shown). As for the designation or setting of a program to be repeatedly recorded such as a continuous drama, a repetitive reservation is automatically set based on information included in the program information (here, a flag indicating a continuous program) in addition to the designation by the user. be able to.

  In step S58, if there is no repeated reservation setting for the recorded program, the title of the program is added as exclusive information to the search information in the automatic reservation information DB 27b so that the program is not duplicated. To do. This avoids unnecessary duplicate recording.

  As described above, according to the first embodiment of the present invention, at the time of automatic reservation such as rebroadcasting, based on the search condition when the program reservation information is detected from the EPG data at the previous automatic reservation, and other pieces of program information In addition, it is possible to set program search conditions wider than the previous time, and recording reservation and recording can be performed without missing a rebroadcast program.

  In the present invention, as in the above-described embodiment, the search condition is the same as the previous time, not limited to the case where the recording reservation range is widened or narrowed as a result of widening or narrowing the search condition. However, when the recording reservation is actually set in the reservation information DB, the case where the recording reservation setting is performed in addition to the program setting information from the recorded program information DB is also included.

  Therefore, according to the present invention, it is possible to perform a multi-faceted search (a wider or narrower search range than the previous search) using the original search condition and a plurality of other program information using a search condition different from the previous search condition. Thus, it is possible to perform recording reservation and recording by performing a more appropriate program search. Specifically, using the original search condition and other pieces of program information, setting a broader program search condition than the previous time (for example, mainly using OR search with a plurality of pieces of information) This includes the case of setting a program search condition narrower than the previous time (for example, mainly using AND search with a plurality of information) using the search condition and other pieces of program information.

  Based on program information (telop, emergency broadcast, program change, etc.) distributed at the same time as program broadcast in digital broadcasting, etc., broadcast content change / abnormality detection means, telop insertion into scheduled recording program, emergency program interruption, Based on information indicating program change, automatically detects that the received program is not normal, and when the same program is rebroadcast, it automatically searches for the rebroadcast program using search information and program information related to the same program. Recording reservation and recording are possible.

  When a user views a program that has been reserved and wants to record again, the user can instruct automatic recording again by the recording success / failure user setting means, and automatically when the same program is rebroadcast. Record reservation and recording are possible.

  If it is determined by the broadcast content change / abnormality detection means that the reserved recording has been completed normally, the program title is registered as an exclusive condition in the search condition for automatic reservation setting by the automatic reservation setting means, so that the program of the same title It is possible to avoid re-recording (double recording) when re-broadcasting.

  When an automatic reservation is registered by the automatic reservation setting means at a time overlapping with an already reserved program, the user is notified of the reservation overlap by a display device of the program record storage device and / or e-mail. Alternatively, when the time of a program that has already been automatically reserved by the automatic reservation setting means overlaps with a program for which the user has newly specified a reservation, the user is similarly notified of the reservation overlap. (Note that in the past, systems that prioritize manual settings and systems that prioritize newer ones that were later set for reservation can be found. However, in this embodiment, manual reservations and new reservation settings are not necessarily prioritized. (It is not necessarily expensive, so if a reservation overlaps in time, this is notified to the user so that the user can select and decide which reservation is really good.)

Next, Example 2 of the present invention will be described.
The configuration of the second embodiment of the present invention is the same as the configuration of the program record storage system of the first embodiment shown in FIG.

  In the second embodiment, the broadcasting station 3 as the first transmitting device includes first information including program schedule information of program broadcasting and information specifying which broadcast date and time of the past the program is rebroadcast as other information. The program information is sent out. The broadcast station 5 as the second transmission device transmits a program broadcast and rebroadcasts the program at any broadcast date and time in the past that is inserted into the first program information to the broadcast station 3 and the information providing company 2. Provide information that identifies whether

  On the other hand, the program record storage device 1 can receive the first program information transmitted from the broadcast station 3 and can receive the program broadcast broadcast from the broadcast station 5. Setting means for acquiring the transmitted first program information, receiving means for receiving the program broadcast transmitted from the broadcasting station 5, and search information including past broadcast date and time of automatic reservation input by the user And an automatic reservation capable of reserving a recording of a rebroadcast program whose past broadcast date / time has been specified by searching for the first program information based on the search information and reserving the recording of the program. It comprises at least setting means and means for recording a program received by the receiving means on an HDD or the like as a recording device based on the recording reservation of the automatic reservation setting means.

  According to the second embodiment of the present invention, as the first program information sent from the transmission side, the program schedule information and other information other than the above are specified as the past broadcast date and time of the rebroadcast of the program. Since the information transmission system is used, even if there is a program that failed to be recorded, if the rebroadcast is to be broadcast in the future, the search condition input by the user for receiving the rebroadcast is any of the past broadcasts. By preparing a search condition including information specifying whether or not the program is rebroadcast on the date and time, it is possible to reliably perform recording reservation and recording of the rebroadcast program.

  It should be noted that instead of using information for identifying which broadcast date and time of the program was rebroadcast as one of the search conditions, a search is performed using “rebroadcast” as one of the search conditions, and a plurality of searched rebroadcasts are searched. The past broadcast date and time included in each program may be presented on the display means, and the user may select a desired one rebroadcast program from there and perform recording reservation and recording.

  INDUSTRIAL APPLICABILITY The present invention is useful for automatic recording reservation by being installed in an HDD recorder capable of recording and reproducing, a DVD recorder and DVD recorder capable of recording and reproducing, or a digital television receiver (DTV).
