Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a program recording apparatus for recording a program broadcast on a television broadcast or the like on a recording medium, and a recorded program management method for managing the recorded program.
[0002]
[Prior art]
Conventionally, recording a television broadcast program on a program recording device such as a video deck (VCR) is routinely performed even in ordinary households. When making a reservation for recording a program in advance, generally, the user looks at the program column of a newspaper or magazine, finds a desired program according to the user's preference, confirms the broadcast time of the program, and sets a channel for the VCR. The procedure of setting the number, broadcast date, recording start time, and recording end time is performed. In other words, a reservation list such as the date, day of the week, recording start time, recording end time, channel number, etc. stored in the VCR is transferred to the VCR display unit or television (TV) screen connected to the VCR. Displaying and allowing the user to input each item data in the reservation list makes a recording reservation for a desired program.
[0003]
In addition, in order to simplify this reservation operation, a number called a G code of 8 digits or less posted for each program in a program column of a newspaper or a television magazine is inputted to a remote controller or the like and transferred to the VCR main body. Therefore, there is a method for making a recording reservation for a program.
[0004]
By the way, when making a recording reservation as described above, the user individually checks information such as a channel number, a broadcast date, a recording start time, and a recording end time regarding a desired program in a newspaper or a magazine. An operation such as inputting or inputting a numerical array of G codes is required. For this reason, the contents of the recording reservation may be set erroneously due to an input operation error.
[0005]
On the other hand, recently, the number of programs provided by TV broadcasting such as cable TV and digital satellite broadcasting often exceeds 100 channels. When the number of channels is small, it is only necessary to sequentially check the contents broadcast on each channel and select a desired program. However, when the number of channels increases, such a method can confirm all programs. It becomes difficult.
[0006]
In view of this, viewing navigation such as EPG (Electronic Program Guide) has been proposed as a means of leading the selection of programs by compensating for such inconvenience. As EPG, program information is described in text (Hyper Text Markup Language; HTML, etc.) and multimedia screens provided (MHEG-5 and extended HTML) are roughly divided into two types. A form has been proposed. This EPG is multiplexed with broadcast radio waves and transmitted together with video data and audio data. Then, on the TV side corresponding to the digital broadcast that is a receiver of the broadcast radio wave, the EPG data portion is extracted, interpreted, and a viewing navigation screen is displayed (for example, see Patent Document 1).
[0007]
Based on program information provided by EPG, etc., a desired program can be selected according to a program category or keyword, and a recording reservation can be made for the selected program based on the program information. There is also a technique (for example, Patent Document 1 or 2).
[0008]
In addition, the program information is recorded on a recording medium such as a DVD-RAM so that a recording reservation can be made based on the program information, and at the time of actual recording, the recording of the program information is recorded. A technique for recording a moving image in a “moving image recording area” in a medium is disclosed in Patent Document 3. In this technique, recording reservation information and index information after recording are recorded in the “program and index information recording area” of the recording medium. As the index information, “program title”, “type”, “recording date / time”, “recording start position”, “recording time”, and the like of each recorded program recorded based on the program information and the recording reservation information are recorded. Thus, a recording reservation is made by directly specifying a desired program from a program table created based on the program information, and the recording reservation information is managed in correspondence with the program information of the designated program recorded in the index information recording area. In addition, when the program is actually recorded in accordance with the recording reservation information, the index information is recorded in a form in which an image of the recording reserved program is recorded in the moving image recording area and added to the corresponding program information. Can be recorded and managed.

[Problems to be solved by the invention]
The EPG is an excellent technique in that it enables a recording reservation to be performed accurately and easily. However, EPG cannot distinguish a program that has already been recorded from a program that has not been recorded, or make it possible to quickly grasp the contents of a recorded program.
[0013]
That is, since a recording medium such as an optical disc that is being used for recording a program can perform high-density recording, the user is more likely to record more programs on one recording medium than ever. Also, it is rare that a recorded program is viewed and deleted before recording another program. As a result, the number of programs recorded on one recording medium is greatly increased. Such a situation is likely to occur, for example, when a large number of programs are shot together on a single recording medium and are concentrated on a weekend or a long holiday.
[0014]
In such a situation, it may be necessary to grasp the contents of each program in order to determine the necessity of storage, prioritize viewing, or confirm the broadcast order for a continuous drama. As a method for grasping the contents, conventionally, a part of each recorded program content is sequentially reproduced to grasp and confirm the contents, and determine the necessity for the storage and the like.
[0015]
However, this method has a problem that it is impossible to quickly grasp the contents because it is necessary to sequentially reproduce a part of the recorded program contents. Further, as described above, when a large number of programs are recorded, there is a problem that much time is consumed only by grasping the contents.
[0016]
Furthermore, a program that is about to start can be recorded by all means. However, since the remaining capacity of the recording medium is small and recording cannot be performed as it is, a situation may arise in which it is desired to recover the recordable capacity by deleting unnecessary programs. In such a situation, if a part of each program content recorded as described above is played back to grasp and confirm the content and determine the necessity for storage, it is in time for the program start time. There may be a problem of not being present.
[0017]
On the other hand, with the technique disclosed in Patent Document 3, by linking program information and index information, a recorded mark is added to a list of program information to be displayed, or an image is output with a different color. Thus, it is possible to easily determine whether or not the program has been recorded.
[0018]
However, in this technique, since the moving image is recorded on the recording medium on which the program information is recorded, the program information and the index information can be associated with each other. Therefore, the program is recorded on the recording medium on which the program information is recorded in advance. There is a limitation at the time of recording such as having to record. For this reason, there is an inconvenience that program information must be recorded in advance on a recording medium. In this case, recording program information reduces the free capacity of the recording medium, resulting in a problem that the capacity for actually recording a program is reduced.
[0019]
Also, with this technique, since index information is recorded on the recording medium based on the recording reservation information, there is a restriction at the time of recording such that the recording must be reserved for recording. That is, when recording is performed by the user pressing the recording button while watching a program without making a recording reservation, management based on the index information cannot be performed.
[0020]
The present invention has been made in view of the above-mentioned problems, and its purpose is to facilitate the recording of a program recorded on a recording medium and a program that is not so without being subject to the above-described restrictions during recording. An object is to provide a program recording apparatus and a recorded program management method that can be identified.
[0021]
[Means for Solving the Problems]
The program recording apparatus of the present invention records the broadcast content on a recording medium, and associates with the recorded content, the first identification information capable of specifying the recording time zone and channel in the recording medium. Recording means for recording, electronic program guide data acquisition means for acquiring electronic program guide data prepared in advance to constitute a program guide for a plurality of broadcast programs, and extracting the first identification information from the recording medium And an identification information extracting means for extracting, from the acquired electronic program guide data, second identification information associated with each program capable of specifying a time zone and a channel in which each program is broadcast, and the extraction On the basis of the first identification information and the second identification information, the correspondence between the recorded content recorded on the recording medium and the program in the program guide configured by the electronic program guide data is determined. It is characterized by comprising a recognition means for identification.
[0022]
In addition, the recorded program management method of the present invention records the broadcast content on a recording medium, and associates the first identification information with which the recorded time zone and channel can be specified in association with the recorded content. A step of recording on a recording medium, a step of obtaining electronic program guide data created in advance to constitute a program guide of a plurality of broadcast programs, and extracting the first identification information from the recording medium; Extracting from the acquired electronic program guide data second identification information associated with each program capable of specifying a time zone and a channel in which each program is broadcast; and the extracted first identification information; Based on the second identification information, a step of recognizing a correspondence relationship between the recorded content recorded on the recording medium and the program in the program guide configured by the electronic program guide data. It is characterized in that it comprises and.
[0023]
In the above configuration or method, based on the first identification information and the second identification information, the recorded content already recorded on the recording medium corresponds to which program in the electronic program guide data for constituting the program guide. Can recognize. Therefore, by using this recognition result, for example, it is possible to distinguish and display programs that are already recorded in the program table and programs that are not.
[0024]
Here, the first identification information is information that is recorded on the recording medium in association with the recording content, and that enables the time zone and channel in which the recording is performed to be specified. The second identification information is information that is associated with each program and enables specification of a time zone and a channel in which each program is broadcast. Therefore, by comparing the first identification information and the second identification information, it is possible to easily determine which program is included in the recorded content.
[0025]
By recognizing the correspondence between the recorded content and the program based on the first identification information and the second identification information, the second recording information is recorded on the recording medium on which the first identification information and the recording content are recorded. Even when the electronic program guide data including is not recorded, the correspondence can be recognized. That is, it is possible to eliminate the restriction that the recorded contents must be recorded on a recording medium in which electronic program guide data including the second identification information is recorded in advance. Accordingly, it is possible to avoid a decrease in the capacity that can be recorded on the recording medium by recording the electronic program guide data including the second identification information. It is also possible to acquire the electronic program guide data after recording the recorded contents and recognize the correspondence.
[0026]
Further, even when the first identification information and the recorded content are recorded on the recording medium regardless of the second identification information, the correspondence can be recognized. That is, it is possible to eliminate the restriction that recording must be performed after recording reservation is made based on the second identification information.
[0027]
When comparing the first identification information and the second identification information, the time zone in which the recorded contents are recorded and the broadcast time zone of the program completely coincide with each other. Even when the parts match, it may be preferable to recognize that there is a correspondence. This is because, even if the broadcast time zone of the program and the time zone during which the recording is performed are not exactly the same, it can often be regarded as substantially corresponding. For example, it is assumed that the means for generating information such as the time in the program recording apparatus generates information including an error, or the recording start and end times are adjusted in consideration of the time of the commercial or the like. This is because that.
[0028]
The program recording apparatus of the present invention recognizes that the recognition means corresponds to the recorded contents recorded on the recording medium while generating display data for displaying the program guide based on the electronic program guide data. It is desirable to provide a program table creation means for editing the display data so that the displayed program is displayed with a display method different from that of other programs.
[0029]
In the recorded program management method of the present invention, display data for displaying the program guide is generated based on the electronic program guide data, and the recorded content recorded on the recording medium by the recognition means is used. It is desirable to include a step of editing the display data so that a program recognized as corresponding is displayed with a display method different from that of other programs.
[0030]
In the above configuration or method, when a program guide is displayed, a program recognized as corresponding to the recorded content recorded on the recording medium has a display method different from other programs, that is, a difference in viewing angle occurs. It can be displayed by such a display method. As a result, a user who has viewed the displayed program guide can easily discriminate between programs recorded on the recording medium and programs not recorded.
[0031]
In addition, in order to change the display method, for example, in a program table in which a program is displayed for each cell, the background color of the cell is changed, the typeface or color of the program name in the cell is changed, a specific type, etc. A method such as adding hatching to a cell or displaying a specific cell in three dimensions is conceivable. Further, for a program corresponding to the recorded content, information related to the program included in the electronic program guide data may be displayed, and such a display may not be performed for a program that does not correspond.
[0032]
Further, the display style of the program guide is preferably one according to a display format such as a newspaper or a magazine. According to this, there is no sense of incongruity compared to the case where the program is simply displayed as a list, and it is easy to check whether the program has been recorded.
[0033]
The program recording apparatus of the present invention searches for additional information included in the electronic program guide data and associated with the second identification information under a condition input by a user. The display means for selecting the specific second identification information and the display data for displaying the program guide based on the electronic program guide data are generated and recorded on the recording medium by the recognition means. Creation of a program guide that edits the display data so that a program that is recognized as corresponding to the recorded content and that corresponds to the selected second identification information is displayed in a display method different from other programs It is desirable to provide means.
[0034]
In the above configuration, when a program guide is displayed, a program that is recognized as corresponding to the recorded contents recorded on the recording medium and meets the conditions input by the user is displayed with a display method different from that of other programs. Can be displayed. As a result, the user who has viewed the displayed program guide can easily find a program that meets the conditions input by the user among the programs recorded on the recording medium.
[0035]
The “other programs” include programs that are recorded on the recording medium but do not meet the conditions input by the user, and programs that are not recorded on the recording medium. These may be displayed by the same display method, or may be displayed by different display methods.
[0036]
The program recording apparatus of the present invention comprises information acquisition means for acquiring, from the electronic program guide data, additional information relating to a program recognized by the recognition means as corresponding to the recorded content recorded on the recording medium. desirable.
[0037]
In the above configuration, it is possible to acquire additional information about the recorded content recorded on the recording medium, and by displaying this, the user can obtain additional information about the recorded content. Therefore, it is possible to easily determine whether or not the recording content is necessary based on the additional information and erase the unnecessary recording content without actually reproducing the recording content. As the additional information, outline contents of the program, detailed information on the performers, one scene of the program, and the like can be considered.
[0038]
In the program recording apparatus of the present invention, it is desirable that the recording means records the acquired additional information on the recording medium.
[0039]
In the above configuration, by recording the additional information on the recording medium, the additional information can be acquired from the recording medium and used even in a situation where the electronic program guide data cannot be acquired later.
[0040]
In the program recording apparatus of the present invention, when recording to the recording medium is performed across a plurality of broadcast programs by the recording means, the first identification information associated with the recorded content, It is desirable to provide program dividing means for dividing the recorded content based on the second identification information extracted from the electronic program guide data and newly giving the first identification information to each divided recorded content. .
[0041]
In the above configuration, when a plurality of broadcast programs are continuously recorded, the recording content is divided for each program based on the second identification information that can specify the broadcast time zone of each program, The first identification information can be given again. Therefore, it is possible to easily find each program based on the first identification information given again.
[0042]
In the electronic program guide data, when the program is a rebroadcast program, the program recording apparatus of the present invention associates with the second identification information of the rebroadcast program and has the same contents as the rebroadcast program. Includes the second identification information of the previous broadcast program broadcasted, and corresponds to the first identification information based on the second identification information of the rebroadcast program and the second identification information of the previous broadcast program. It is desirable to provide recording control means for controlling the recording means so as to record the unrecorded portion when the recorded content includes an unrecorded portion of the previous broadcast program.
[0043]
In the above configuration, when a part of a broadcasted program (previous broadcast program) is missed to be recorded, a part of the program (rebroadcast program) that has failed to be recorded later (not yet broadcast) It is possible to record so as to supplement the recording portion. That is, the second identification information of the rebroadcast program that can specify the time zone and the channel in which the rebroadcast program is broadcast, and the second identification information of the previous broadcast program that can specify the time zone and the channel in which the previous broadcast program was broadcast And based on the first identification information that can specify the time zone and the channel in which the recorded contents are recorded, it becomes possible to recognize the unrecorded part and record the part.
[0044]
The program recording apparatus of the present invention discriminates whether or not the identification means for identifying the user and the recording medium or the recorded contents recorded on the recording medium are usable by the user identified by the identification means. It is desirable to provide the authentication means to do.
[0045]
In the above configuration, the recording medium and the recording contents can be managed for each user, and it is possible to prevent other users from accidentally recording on the recording medium or deleting the recording contents. it can. Further, it is possible to prevent other users from reproducing the recorded content.
[0046]

[0052]
The playback unit 12 is a recording medium (programs) on which electronic program guide data created in advance by a broadcast-related information provider or the like is recorded in order to form a program guide of a program that is broadcast on a large number of channels within a certain period of time. Information media).
[0053]
The recording / reproducing unit 13 records a program received by the broadcast receiving unit 16 on a recording medium (recording medium) that can record a broadcast program, and reproduces the recorded content. is there.
[0054]
The control unit 11 includes a program information processing unit 21 that performs various processes using the electronic program guide data reproduced by the reproduction unit 12, and a display screen generation that generates display data for displaying a program guide based on the electronic program guide data. 25, a channel control unit 27 for controlling the channel received by the broadcast receiving unit 16, a recording / reproduction processing unit 26 for performing various processes of recording on the recording medium and reproduction from the recording medium, program information medium, and recording An ID comparison unit 22, an ID extraction unit 23, and an ID generation unit 24 that perform various processes related to the program ID and the recording ID included in each medium are included.
[0055]
An example of the format of the program information included in the electronic program guide data read from the program information medium by the reproduction unit 12 is shown in FIG. Electronic program guide data is composed of a set of program information.
[0056]
The program information corresponds to each program, and includes a program ID that is information that can specify a channel and a broadcast time zone displayed in a program column of a conventional newspaper or magazine. Assuming a program ID in which a broadcast time zone is from 18:00 to 18:54 on June 20, 2002 and the broadcast channel is 2 channels, for example, “02062018001854002” configured by arranging these numbers. Is given as a string of numbers. The broadcast channel means a channel assigned to each broadcast station, for example, in terrestrial broadcast, satellite broadcast, CATV, or the like. The program information includes additional information 1 to 3 as information relating to the program. Additional information 1 includes program name and performer information, additional information 2 includes information such as program contents, genre, and keyword, and additional information 3 includes one scene (still image or moving image) of the program.
[0057]
Here, as a broadcast channel number, for example, “002” is associated with channel 2, but a number for distinguishing the region may be added thereto. For example, “06” may be added to “06002” for a program broadcast in Kansai, and “03” may be added to “03002” for a program broadcast in Kanto. As a result, even when the broadcast channel differs for each reception area, the program can be specified accurately.
[0058]
The program information is reproduced from the program information medium by the reproduction unit 12 and the content is recognized by the program information processing unit 21. Then, based on the contents recognized by the program information processing unit 21, the display screen generating unit 25 configures a display screen of the program table 31 as shown in FIG. 4 and displays it on the display unit 18. FIG. 4 shows a program table for about one day, but a longer program table such as one week or one month can be displayed by, for example, scrolling the screen. desirable.
[0059]
As information displayed on the program guide 31, there are a program name 32 and a performer 33 as information of the additional information 1, in addition to a channel obtained from the program ID and a broadcast time zone. Information of each program is displayed in a program cell 35 that is divided by a broadcast time zone and a broadcast channel in the program guide 31.
[0060]
When other additional information is included in the program information, an icon 34 corresponding to the additional information is also displayed in the program cell 35. Then, the user operates the selection cursor 36 displayed on the program guide 31 with the selection button 3a (see FIG. 2) of the remote controller 3 to select a specific icon 34, as shown in FIG. In addition, additional information is displayed on the additional information screen 37. 4 and 5, the icons 34 are simply illustrated as “▲ 1”, “2”, and “3”, but the icons 34 have a design corresponding to program information. Also good.
[0061]
The program recording apparatus 1 can make a recording reservation using the program guide 31. That is, the user can make a recording reservation by operating the selection cursor 36 with the selection button 3a of the remote controller 3 and selecting the program name 32 of the program to be recorded. At this time, the program information processing unit 21 sets the broadcast start time, the broadcast end time, and the broadcast channel based on the program ID in the recording / playback processing unit 26. As a result, when the broadcast start time comes, the recording / playback processing unit 26 sets the channel received by the broadcast receiving unit 16 to the channel set by the recording reservation and starts recording by the recording / playback unit 13. When the broadcast end time is reached, recording by the recording / playback unit 13 is stopped.
[0062]
As a result, it is possible to easily make a recording reservation without a complicated operation such as selecting a program name from a program column of a newspaper or a magazine, inputting a broadcast start time, or inputting a G code as in the past. Will be able to.
[0063]
In the program recording apparatus 1, when recording is performed on the recording medium by the recording / playback unit 13, one recording is performed for the series of recording contents (a series of recording contents from the recording start to the recording end) by the ID generation unit 24. An ID is assigned, and this recording ID is recorded by the recording / playback processing unit 26 in association with the recorded contents. An example of the format of the recording contents and the recording ID is shown in FIG. Assuming that the recording time zone is from 18:00 to 18:54 on June 20, 2002 and the recording channel is assumed to be two channels, for example, “02062018001854002” configured by arranging these numbers side by side. Given as a string of numbers. As described above, the recording ID is a numeric string defined in the same format as the program ID of the program information. By comparing the recording ID with the program ID, the recorded content and the program information are matched or not matched. It can be discriminated.
[0064]
Next, the processing operation of the program recording apparatus 1 will be described. First, the overall processing operation of the program recording apparatus 1 will be described with reference to FIG. When the program recording apparatus 1 is turned on, the process proceeds to step S1 (hereinafter, “step” is omitted and simply referred to as “S1” or the like). In S <b> 1, it is determined whether or not a recording medium is inserted in the playback unit 12. If it is inserted, it is further determined whether or not the recording medium is a program information medium (S2). If it is a program information medium, the process proceeds to S3, where the program information processing unit 21 extracts program information, and the display screen generation unit 25 creates a display screen of the program guide and displays it on the display unit 18. Then, it is determined whether or not a recording medium is inserted in the recording / playback unit 13 (S4). Here, when a recording medium is also inserted into the recording / playback unit 13 and the recording medium includes the recording contents and can be linked to the program information medium (S5), a recording medium to be described later The operation proceeds to the operation of linking between the recording media (see the link routine between recording media, see FIG. 8) (S6). If the recording medium does not contain the recorded content and cannot be linked to the program information medium (S5), the program moves to a program recording routine (see FIG. 10) described later so that the program can be recorded (see FIG. 10). S11).
[0065]
If no recording medium is inserted into any of the playback unit 12 and the recording / playback unit 13, the user is notified that no recording medium is inserted (S7, S12). As a notification method, an error message indicating that the recording medium is not inserted is displayed on the display unit 18, or a warning lamp provided at a predetermined position of the main body 2 is turned on or off. It is done.
[0066]
If no program information medium is inserted in the playback unit 12 and a recording medium is inserted in the recording / playback unit 13 (S7), the program recording routine (see FIG. 10) described later is entered. So that the program can be recorded (S8).
[0067]
Further, if the recording medium inserted in the playback unit 12 is not a program information medium but a recording medium (DVD-video or the like) on which video information is recorded, the playback unit 12 shifts to a playback mode and the playback unit 12 While starting reproduction, video information is output to a television (not shown) connected to the program recording apparatus 1 (S9, S10).
[0068]
FIG. 8 shows a flowchart of the recording medium link routine. In this routine, information between recording media is linked between the program information medium of the reproducing unit 12 and the recording medium of the recording / reproducing unit 13.
[0069]
The program information read from the program information medium of the reproduction unit 12 is given a program ID for identifying the program as described with reference to FIG. Further, as described in FIG. 6, the recording ID associated with the recording content is recorded in the recording medium of the recording / playback unit 13. By comparing the program ID with the recording ID, the recorded content recorded by the recording / reproducing unit 13 and the program information of the program information medium are linked, that is, the recorded content recorded by the recording / reproducing unit 13; The correspondence relationship with the program in the program table can be recognized.
[0070]
As a processing operation, first, the ID extraction unit 23 extracts a program ID from the program information acquired by the program information processing unit 21 and records it in the memory 15 (S21). Subsequently, the ID extraction unit 23 extracts the recording ID recorded on the recording medium of the recording / playback unit 13 and records it in the memory 15 (S22).
[0071]
When the extraction of the program ID and the recording ID is completed, the ID comparison unit 22 compares the program ID and the recording ID (S23). Here, for example, when a two-channel broadcast is recorded on the recording medium of the recording / playback unit 13 from 18:30 to 18:50 on June 20, 2002, the recording ID “02062018301850002” is included. Will be. On the other hand, if there is a two-channel program from 18:00 to 18:54 on June 20, 2002 as the program information of the program information media, the program ID is “02062018001854002”.
[0072]
The ID comparison unit 22 compares these, and if the channel number of the recording ID matches the channel number of the program ID and the time zone of the recording ID partially overlaps the time zone of the program ID, the recording ID The recorded contents corresponding to the program ID and the program information corresponding to the program ID are linked. As described above, the link between the recording content and the program information is not only when the recording ID and the program ID completely match, but also when the channel number of the recording ID and the program ID match and the time zone is the same. It is desirable to hold even when there are overlapping parts. This is because even if the broadcast time zone of the program and the recording time zone do not exactly match, in many cases it can be regarded as substantially corresponding. For example, information related to the time from the date / time information generation unit 14 that is referred to when generating the recording ID includes an error, or the start / end time of the recording is adjusted in consideration of a time such as a commercial. This is because it is assumed.
[0073]
Since a plurality of recording IDs and program IDs are usually recorded, the combinations of all recorded recording IDs and program IDs are compared in S23. In this way, all combinations are compared, and when the link is completed, the ID comparison unit 22 stores the link result, that is, the correspondence relationship between the recording ID and the program ID in the memory 15.
[0074]
Then, the display screen generation unit 25 as a program table creation unit generates display data for displaying the program table based on the electronic program table data acquired by the program information processing unit 21 and is stored in the memory 15. Based on the link result, the display data is edited so that the program of the program information for which the link is established is displayed in a display method different from other programs (S24).
[0075]
In order to display a program in a different display method, the program cell of the target program is displayed in a character color different from the program name of the other program in the program table. A background color different from that of the target program, hatching the program cell of the target program, displaying the program cell of the target program in three dimensions, displaying additional information such as the program name only for the target program, etc. A method is conceivable. Then, the display unit 18 displays the edited program table (S25).
[0076]
The program guide displayed by the display unit 18 is, for example, as shown in FIG. In FIG. 9, the program cell of the program information for which the link is established is hatched. As a result, the user can distinguish the program for which the link is established, that is, the already recorded program from other programs at a glance.
[0077]
As described above, when a link is established between the recording media, the additional information such as the program name of the program recorded on the recording medium on the recording / playback unit 13 side, the performer, the program content, and the like is obtained using the link. It can be read from the program information medium on the 12th side by the program information processing unit 21 as information acquisition means (S26). For this reason, the user can easily obtain information on the recorded program. Therefore, even when a plurality of programs are recorded on the recording medium of the recording / playback unit 13, the contents of the program can be grasped without reproducing a part of the recorded program by using the program information in which the link is established. be able to. And based on the grasped program content, it is possible to easily reproduce a program to be reproduced or delete an unnecessary program. The program can be reproduced or deleted by selecting the program for which the link is established with the selection cursor 36.
[0078]
In the above, the program information program for which the link has been established is displayed in a display method different from other programs. However, the program information program for which the link has been established is displayed, and the program shown in FIG. A program in which the additional information 1 to 3 meets a predetermined condition may be displayed by a display method different from other programs. For this purpose, the additional information 1 to 3 included in the electronic program guide data and associated with each program ID is searched under the conditions input by the user, and a specific program ID is obtained. The program information processing unit 21 is made to function as a search means for selecting and a program table based on the electronic program guide data acquired by the program information processing unit 21 is displayed by the display screen generation unit 25 as a program guide creation means. While generating the display data, the ID comparison unit 22 recognizes that it corresponds to the recording content recorded on the recording medium, and corresponds to the specific program ID selected as described above by the program information processing unit 21. It is only necessary to edit the display data so that the program is displayed in a display method different from other programs.
[0079]
As a result, the user who has viewed the displayed program guide can easily find a program that meets the conditions input by the user from among the programs recorded on the recording medium. Note that programs that are recorded on the recording medium but do not meet the conditions entered by the user and programs that are not recorded on the recording medium may be displayed in the same display method or in different display methods. May be.
[0080]
In addition, the recording / playback processing unit 26 may record additional information read by the program information processing unit 21 for a program for which a link has been established, on a recording medium in association with the recording content. Thereby, even in a situation where the electronic program guide data cannot be acquired later, the additional information can be read from the recording medium and used.
[0081]
For the recording media for which no link is established in S23, the processing of S26 using the link cannot be performed (S27). However, when a new program is recorded on this recording medium, Since the recording ID is given, the link is established after that, and the process of S26 using the link can be performed.
[0082]
Next, recording processing by the program recording apparatus 1 will be described. When recording, as shown in FIG. 10, recording and display by the recording start button 2c of the main body 2 or the recording start button 3b of the remote control 3 (refer to FIG. 2, hereinafter simply referred to as “recording start button”). It is discriminated whether the reserved recording based on the program guide displayed in the section 18 or the reserved recording by keyword search (S31, S32, S33), and the process proceeds to the corresponding routine (S34, S35, S36).
[0083]
Before describing each recording routine, a recording routine common to each recording routine will be described based on the flowchart of FIG. When starting the recording operation, first, the ID generation unit 24 acquires the recording start time from the date / time information generation unit 14 and records it in the memory 15 (S41). Then, the recording / playback processing unit 26 starts program recording by the recording / playback unit 13 and starts recording on the recording medium (S42). When the stop button 2d of the main body 2 or the stop button 3c of the remote controller 3 (see FIG. 2, hereinafter referred to simply as “stop button”) is pressed during program recording, or at the broadcast end time set in the recording reservation. When the recording / reproduction processing unit 26 has been reached, the recording / reproduction processing unit 26 ends the program recording by the recording / reproduction unit 13 (S43), and the ID generation unit 24 acquires the recording end time from the date / time information generation unit 14 and records it in the memory 15. (S44). The ID generation unit 24 acquires the current date from the date / time information generation unit 14, acquires the recorded channel from the channel control unit 27, and the recording start time and recording end time recorded in the memory 15. Based on the above, a recording ID is created, and the created recording ID is recorded on the recording medium in association with the recording content (S45).
[0084]
Next, each recording routine shown in FIG. 10 will be described below. First, the recording routine (S34 in FIG. 10) using the recording start button will be described based on the flowchart in FIG. In this routine, it is determined whether or not the recording start button has been pressed (S51). When the recording start button is pressed, the routine proceeds to the recording routine of FIG. 11 (S52).
[0085]
As described above, even when the recording is manually performed using the recording start button, the recording content is assigned with the recording ID and recorded on the recording medium. Linking with information media becomes possible, and information related to the program can be obtained.
[0086]
Next, a recording routine based on the program guide (S35 in FIG. 10) will be described based on the flowchart in FIG. This routine is created by the display screen generation unit 25 based on the program information reproduced by the reproduction unit 12, and based on the program table 31 of FIG. 4 displayed by the display unit 18, the program names in the program table 31 are displayed. Recording reservation is performed by selecting 32 or the like.
[0087]
In this routine, first, it is determined whether or not the user has selected the program name 32 in the program table 31 by operating the selection cursor 36 with the selection button 3a (see FIG. 2) of the remote controller 3 (S61). When the name 32 is selected, the recording / playback processing unit is reproduced based on the program information corresponding to the selected program among the program information that is reproduced by the program information medium of the reproduction unit 12 and acquired by the program information processing unit 21. 26 makes a recording reservation (S62). Specifically, the broadcast date, broadcast start time, broadcast end time, broadcast channel, etc. of the selected program are recorded in the memory 15 as recording reservation information.
[0088]
Thereafter, the broadcast start time of the program reserved for recording is recorded based on the recording reservation information recorded in the memory 15 by the recording / playback processing unit 26 and the date / time information generated by the date / time information generating unit 14. Then, the process proceeds to the recording routine shown in FIG. 11 (S64). After the recording routine ends, the recording / playback processing unit 26 determines whether there is another program that is scheduled for recording (S65), and if there is, the process proceeds to S63.
[0089]
Also in this routine, since the recording ID is given to the recording contents and recorded on the recording medium, it is possible to link with the program information medium of the reproduction unit 12 later, and information related to the program is displayed. You can get it.
[0090]
Next, a recording routine by keyword search (S36 in FIG. 10) will be described based on the flowchart in FIG. This routine searches the program information included in the program information medium of the playback unit 12 based on the keyword input by the user, picks up the program to be recorded based on the search result, and Is reserved for recording.
[0091]
In this routine, the user operates the selection cursor 36 with the selection button 3a (see FIG. 2) of the remote controller 3 and presses a “search menu button” (not shown), whereby the display screen generation unit 25 and the display unit are displayed. 18 displays a search menu screen as shown in FIG. On this search menu screen, the user inputs keywords such as “performer name”, “program content”, “genre”, and the like, using the numeric keypad 3d of the remote control 3 (things that can be input by characters).
[0092]
The program information processing unit 21 determines whether or not the keyword has been input as described above and the search execution button has been pressed (S71). When the search execution button has been pressed, the playback unit is based on the input keyword. The program information acquired from the 12 program information media is searched (S72), and the search result is displayed (S73). The search results are displayed as a search result list screen as shown in FIG. From this search result list screen, schedule recording for all displayed programs, schedule recording for selected programs from among the displayed programs, or further narrow down the displayed programs It is possible to search. The program information processing unit 21 determines which of these has been selected (S74 to S77), and enables selection of a program by each method.
[0093]
When the program is selected in this way, the program information is reproduced on the program information medium of the reproduction unit 12 and recorded / programmed based on the program information corresponding to the selected program among the program information acquired by the program information processing unit 21. The reproduction processing unit 26 makes a recording reservation (S78). Note that S78 to S81 are the same as S62 to S65 described with reference to FIG.
[0094]
Also in this routine, since the recording ID is given to the recording contents and recorded on the recording medium, it is possible to link with the program information medium of the reproduction unit 12 later, and information related to the program is displayed. You can get it.
[0095]
In this routine, when the total recording time of the program selected based on the search result exceeds the free space of the recording medium, a warning to that effect is displayed and the search result list of FIG. On the screen, the list may be displayed in order of recording time or recording day. In this list, information related to each program may be confirmed based on the program information, and the selection may be canceled for a program that the user determines to be unnecessary based on the information. Further, after the keyword search, a program to be recorded may be further added from the program table.
[0096]
In the recording routine by the program guide and the recording routine by keyword search, the recording reservation information in the recording reservation is recorded in the memory 15, but in addition to this, it is recorded in the recording medium of the recording / playback unit 13. You may do it. According to this, when the recording medium is once taken out from the recording / playback unit 13, when the recording medium is inserted again, the recording reservation information can be read and the recording reservation can be continued. Further, when the broadcast start time has passed while the recording medium is being taken out, it is possible to notify the user of information that has not been recorded using the display unit 18.
[0097]
As described above, in the program recording apparatus 1, the recording date / time and the like match between the program information medium in which the program information of the reproducing unit 1 is recorded and the recording medium in which the program is recorded in the recording / reproducing unit 13. If so, information related to the program recorded on the recording medium can be obtained from the program information medium of the playback unit 12. Thus, unnecessary programs can be deleted from the programs recorded on the recording medium while referring to information included in the program information. Further, by using this program information, it is possible to easily make a recording reservation for a desired program from among the enormous and diversified programs provided by multiple channels.
[0098]
In the above description, when the program information processing unit 21 acquires program information, the program information processing unit 21 always acquires the program information from the program information medium of the playback unit 12, but when the program is recorded, The acquired program information may be recorded on the recording medium of the recording / playback unit 13. In this case, the program information can be obtained even if the program information medium is not inserted into the playback unit 12 during playback. At this time, when recording the program, only the necessary program information is recorded on the recording medium of the recording / playback unit 13 by the user setting, so that only the minimum necessary information is recorded. Can be recorded, and the reduction of the recordable time in the recording medium can be mitigated.
[0099]
As described above, the program recording apparatus 1 (program recording apparatus) records the broadcast content on the recording medium (recording medium), and records the recording (recording) in association with the recorded content (recording content). A recording / playback unit 13 and a recording / playback processing unit 26 as recording means for recording a recording ID (first identification information) capable of specifying a time zone and a channel on the recording medium, and a plurality of broadcast programs The program ID information is extracted from the playback unit 12 and the program information processing unit 21 as electronic program guide data acquisition means for acquiring the electronic program guide data prepared in advance to form the program guide, and the recording ID is acquired. Identification information extracting means for extracting a program ID (second identification information) associated with each program capable of specifying a time zone and a channel in which each program is broadcast from the electronic program guide data Based on the ID extraction unit 23 and the extracted recording ID and program ID, the correspondence between the recorded content recorded in the recording medium and the program in the program guide composed of the electronic program guide data is determined. An ID comparison unit 22 as a recognition means for recognition is provided.
[0100]
In the program recording apparatus 1, based on the recording ID and the program ID, it is possible to recognize which program in the program table corresponds to the recording content already recorded on the recording medium. Therefore, by using this recognition result, for example, a program that has already been recorded in the program table and a program that is not so can be displayed separately.
[0101]
Here, the recording ID is information that is recorded on the recording medium in association with the recording content, and that can specify the time zone and the channel in which the recording was performed. The program ID is information that is associated with each program and that can specify a time zone and a channel in which each program is broadcast. Therefore, by comparing the recording ID and the program ID, it is possible to easily determine which program is included in the recorded content.
[0102]
By recognizing the correspondence between the recording content and the program based on the recording ID and the program ID, the recording medium in which the recording ID and the recording content are recorded includes electronic program guide data including the program ID. Even if no is recorded, the correspondence can be recognized. That is, it is possible to eliminate the restriction that the recorded contents must be recorded on a program information medium in which electronic program guide data including a program ID is recorded in advance. Accordingly, it is possible to avoid a decrease in the capacity that can be recorded on the recording medium by recording the electronic program guide data. It is also possible to acquire the electronic program guide data after recognizing the recording contents and recognize the correspondence.
[0103]
In addition, even when the recording ID and the recording content are recorded on the recording medium regardless of the program ID, the correspondence can be recognized. That is, it is possible to eliminate the restriction that the recording must be performed after making a recording reservation based on the program ID.
[0104]
The present invention can also be understood as a recorded program management method. In this recorded program management method, the broadcast content is recorded on the recording medium, and the recording ID that can identify the time zone and the channel in which the recording is performed is recorded on the recording medium in association with the recorded content. A step of acquiring electronic program guide data created in advance to constitute a program guide for a plurality of programs to be broadcast, extracting a recording ID from the recording medium, and from the acquired electronic program guide data, A step of extracting a program ID associated with each program capable of specifying a time zone and a channel in which each program is broadcast, and a recording recorded in the recording medium based on the extracted recording ID and the program ID And recognizing the correspondence between the contents and the program in the program guide constituted by the electronic program guide data.
[0105]
Next, other processes that can be performed by the program recording apparatus 1 will be described. First, the process of dividing the continuously recorded content into programs will be described. For example, in a recording routine using a recording start button (see FIG. 12), as shown in FIG. 17, a plurality of programs may be recorded continuously without being divided into programs. FIG. 17 shows a case where four channels are recorded continuously from 20:00 to 21:54. In FIG. 17, the areas divided by broken lines correspond to the contents of a plurality of programs A to C included in the recording time period.
[0106]
The link routine of FIG. 8 is performed between the recording medium on which the contents of FIG. 17 are recorded and the program information medium, whereby the ID comparison unit 22 records the recording ID of the recording medium and the program ID of the program information medium. And A to C programs can be recognized as being included in the recording contents of the recording medium. That is, the recorded content is from 20:00 to 21:00, the broadcast time zone of the A program is from 20:00 to 20:54, the broadcast time zone of the B program is from 20:54 to 21:00, the C program It can be recognized that the broadcast time zone is from 21:00 to 21:54.
[0107]
Based on this information, the recording / playback processing unit 26 divides a series of recording contents into programs, assigns recording IDs to the recording contents corresponding to the programs, and sets the recording IDs as the recording contents. Correspondingly, it is recorded on the recording medium by the recording / playback unit 13. As a result, the recording contents of the recording medium are as shown in FIG.
[0108]
In this way, by dividing the recording content into each program based on the program information and assigning a recording ID, when reproducing the recording content, based on the information obtained from this recording ID, Viewing can be started from the C program. As a result, when a plurality of programs are continuously recorded, it is possible to cue without searching for the start time. Further, by dividing the recorded contents for each program, it becomes possible to easily delete only unnecessary programs.
[0109]
As described above, the program recording apparatus 1 extracts the recording ID associated with the recording contents and the electronic program guide data when recording on the recording medium is performed across a plurality of broadcast programs. The recording contents are divided based on the recorded program ID, and an ID comparison unit 22 and a recording / playback processing unit 26 are provided as program dividing means for newly assigning a recording ID to each divided recording content. It is desirable.
[0110]
As a result, when a plurality of programs to be broadcast are continuously recorded, the recording contents are divided into each program based on the program ID that can specify the broadcast time zone of each program, and a recording ID is given again. can do. Therefore, it is possible to easily find each program based on the newly assigned recording ID.
[0111]
Next, a process for supplementing an unrecorded part by rebroadcast when a part of the program has an unrecorded part will be described. FIG. 19 shows the format of program information when information indicating that the program is rebroadcast is added as additional information 4 to the program information. This additional information 4 is a program ID of the same program broadcast before, and is added as a program ID 1, a program ID 2,. In addition, when the same program is repeatedly rebroadcasted, in order to avoid an increase in the amount of information of the additional information 4, only the program IDs for several times from a newer broadcast may be included.
[0112]
Since the recording ID includes information for specifying the recording start time and the recording end time, the recording ID when only a part of the program is recorded in the previous broadcast (main broadcast) and the rebroadcast On the basis of the program ID and additional information 4 in the program information, the recording / playback processing unit 26 calculates the unrecorded time from the recording time zone, and as shown in FIG. You can also record.
[0113]
At this time, there may be an error in the non-recording time due to an error in the set time or the relationship with the commercial time. It is desirable to prevent the part from occurring. The user can freely set how long these overlapping recording portions are set, and the user can delete the overlapping recording portions while reproducing the recorded contents.
[0114]
As described above, when the program is a rebroadcast program, the program recording apparatus 1 associates the program ID of the rebroadcast program with the main broadcast program previously broadcast with the same content as the rebroadcast program (previous time). Electronic program guide data including a program ID of (broadcast program) may be used. Then, based on the program ID of the rebroadcast program and the program ID of the main broadcast program, if there is an unrecorded portion of the main broadcast program in the recording content corresponding to the recording ID, the unrecorded portion is recorded. It is desirable to include a recording / playback processing unit 26 as a recording control means for controlling the recording / playback unit 13.
[0115]
As a result, when a part of the main broadcast program is missed, when a rebroadcast program having the same content is broadcast later, the unrecorded part that was missed can be recorded. That is, the program ID of the rebroadcast program that can specify the time zone and channel in which the rebroadcast program is broadcasted, the program ID of the main broadcast program that can specify the time zone and channel in which the main broadcast program was broadcast, and the recorded contents Based on the recording ID that can specify the time zone and the channel in which recording is performed, it becomes possible to recognize the unrecorded part and record the part.
[0116]
Next, FIG. 21 shows a modification of the program recording apparatus 1 shown in FIG. In the program recording device 51 of FIG. 21, a personal identification unit 52 and an authentication processing unit 53 are newly added. In addition, about the component which has a function equivalent to the component demonstrated in FIG. 1 or FIG. 2, the code | symbol same as the code | symbol used in FIG. 1 or FIG. 2 is attached, and the description is abbreviate | omitted.
[0117]
The personal identification unit 52 is for identifying an individual using a password, fingerprint authentication, or the like, and is provided in a part of the remote control 3, for example, as shown in FIG. The personal identification unit 52 is configured by a device for fingerprint authentication, and by touching the personal identification unit 52 with a finger, an individual can be identified based on the fingerprint of the finger.
[0118]
The personal identification unit 52 may be configured to accept an input of a password using the numeric keypad 3d and identify an individual with the input password.
[0119]
According to this program recording device 51, for example, when sharing with a family of a plurality of people, the whole family is identified by the personal identification unit 52 in advance, and the fingerprints of each person are registered in the memory 15. Then, when actually using the program recording device 51, the authentication processing unit 53 confirms whether or not the inserted recording medium belongs to the user according to the identification result by the personal identification unit 52, It is possible to prevent erroneous recording and deletion by performing control so that recording and deletion cannot be performed unless the user belongs. Also, it is possible to make settings so that only the person himself can play the video during playback.
[0120]
Also, not for each recording medium, but within the same recording medium, a user (administrator) who recorded the program is determined for each program, and the recorded contents are associated with the administrator and recorded on the recording medium. It is also possible to leave. Thus, when an administrator is set for each program, for example, only the administrator name can be displayed in a program recorded with the administrator set in the program guide. . Further, according to the setting of the administrator, it can be set so that the recorded contents cannot be deleted unless personal authentication is performed. Thereby, it is possible to prevent erroneous erasure and the like even in the same recording medium.
[0121]
As described above, the program recording device 51 (program recording device) includes a personal identification unit 52 as identification means for identifying a user, and the recording medium or the recorded content recorded on the recording medium is recorded by the personal identification unit 52. It is desirable to provide an authentication processing unit 53 as an authentication means for determining whether or not the identified user can use it.
[0122]
As a result, it is possible to manage recording media and recording contents for each user, and to prevent other users from accidentally recording on the recording media or deleting the recording contents. it can. In addition, it is possible to prevent other users from reproducing the recorded content.
[0123]
