Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a recording apparatus, a recording method, and a recording medium, and more particularly to a technique for reserving a program using information related to a program preview CM.
[0002]
[Prior art]
In recent years, the number of users who make a reservation for recording a plurality of television programs has increased, and a method for making a reservation for recording a television program has been simplified. For example, it is possible to reserve a program with a small number of operations by using a G code (a compression code represented by a maximum of eight digits for a recording reservation; trademark), an EPG (Electronic Program Guide), or the like. ing.
[0003]
In addition, a proposal for a method of making a recording reservation using a program preview video being viewed is also known, and the following known techniques are mentioned in this regard.
[0004]
First, Japanese Patent Publication No. 8-4327 discloses a technique in which a program recording reservation can be made with a simple operation using time information transmitted in synchronization with a television program preview image being broadcast. .
[0005]
Japanese Patent Application Laid-Open No. Hei 5-207387 discloses that a broadcast program video and program information transmitted in synchronization with the broadcast program video are stored, and the broadcast program video and the stored program information are simultaneously called to store the stored program preview. There has been disclosed a technology that allows a user to make a program recording reservation from a video.
[0006]
Further, JP-A-2001-245229 does not synchronize time information with a broadcast signal and predicts the date and time of a program that is being announced from calendar date data of a program announcement that is broadcast after the end of the broadcast of a television program. There is disclosed a technique for making a recording reservation. An example of a conventional technique for making a recording reservation using program information multiplexed on a broadcast program image and transmitted as described above will be described with reference to a block diagram of FIG. 10 (the configuration of FIG. This is different from the configuration described in the above-mentioned publication.)
[0007]
In the configuration shown in FIG. 10, a broadcast signal from a broadcast station 41 is received by a reception unit 42, and program information multiplexed on the broadcast signal is extracted by an extraction unit 45. The broadcast data received by the receiving unit 42 is stored in the storage memory 44 via the recording unit 43. The stored broadcast data is displayed on the monitor 52 from the display unit 51. The program information extracted by the extraction unit 45 is stored in the storage unit 46, and when the reservation button of the input unit 48 is pressed, the extracted program information stored in the storage unit 46 is sent to the control unit 47. At the same time, time information is acquired from the counter 49, a program is reserved on the basis of the program information and the time information by the reservation unit 50, and the reserved program is stored in the storage memory 44 via the recording unit 43.
[0008]
[Problems to be solved by the invention]
However, in the technology described in Japanese Patent Publication No. 8-4327 and Japanese Patent Application Laid-Open No. 2001-245229, the means for making a program recording reservation corresponds only to a program announcement being broadcast, and There was a problem that program announcements in the data were not supported. In the technology described in Japanese Patent Laid-Open No. 5-207387, such a problem is dealt with by accumulating a program preview video.
[0009]
In the technology described in Japanese Patent Publication No. Hei 8-4327 and Japanese Patent Laid-Open No. Hei 5-207387, recording reservation is made using program information sent in synchronization with a program preview video. When the program information is not synchronized with the video, there is a problem that the recording reservation cannot be made. Furthermore, Japanese Patent Publication No. 8-4327 discloses that program information is incorporated in a vertical retrace period of a broadcast signal, but information incorporated in a retrace period cannot be recorded at present. This is because the flyback period is substantially an unnecessary section, and is specified so as not to be transmitted or recorded in the standard. That is, when the program information incorporated in the vertical flyback period is transmitted or recorded, it is deleted.
[0010]
In the technique described in Japanese Patent Application Laid-Open No. 2001-245229, recording reservation is made by estimating the next broadcast time from the broadcast time of the program preview video instead of the program information transmitted in synchronization with the program preview video. No consideration is given to the extension of baseball broadcasting or the case where there is a special program. Therefore, there is a problem that sudden changes in programs, changes in broadcast time, and cancellations cannot be dealt with.
[0011]
Further, the technique described in Japanese Patent Application Laid-Open No. 5-207387 is capable of performing a recording reservation operation using the stored program preview video. There is a problem that it is not possible to cope with a program pointed to when it has already been broadcast.
[0012]
Further, the technology described in the above-mentioned publication does not disclose a function or a method of searching for and playing back recording data indicated by an arbitrary program preview video from recorded recording data stored and stored. Therefore, there is a problem that when searching for and reproducing arbitrary data from the data reserved for recording, it is necessary to reproduce and search one by one, which is very troublesome.
[0013]
In addition, the technology described in the above-mentioned publication includes a function and a method of acquiring necessary information from a database or the Internet when program information is not synchronized with a broadcast signal and making a recording reservation based on the acquired information. There is no disclosure about.
[0014]
In addition, the technology described in the above-mentioned publication does not disclose a function or a method of automatically making a reservation from a program preview CM in broadcast data already stored in a recording medium or the like.
[0015]
Therefore, the prior art described in the above-mentioned publication has problems to be improved in terms of convenience and usability.
[0016]

It has a configuration including an acquisition unit, a reservation unit for making a recording reservation using the acquired information, and a recording unit for recording from the information for which recording has been reserved.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0019]
The “program announcement CM” referred to in the specification of the present application refers to a program announcement that is flowing as a CM or a program that is flowing as a next announcement in a program such as a drama (generally at the end). (Specifically, for example, 33, 34, 35, and 36 in FIG. 5). The “program information” indicates a start date and time, an end date and time, and a channel number of a program (see FIG. 7).
[0020]
FIG. 1 is a block diagram illustrating a configuration of a recording and playback device according to an embodiment of the present invention. In FIG. 1, 1 is a broadcasting station, 2 is a receiving unit, 3 is a control unit, 4 is a display unit, 5 is an input unit, 6 is a database, 7 is the Internet, 8 is an information acquisition unit, 9 is a reservation unit, and 10 is a reservation unit. A recording unit, 11 is a recording medium, 12 is a calling unit, 13 is a search unit, 14 is a synthesis unit, 15 is a monitor, 16 is an extraction unit, 17 is an audio unit, and 18 is a speaker.
[0021]
In the configuration shown in FIG. 1, a broadcast signal broadcast from a broadcast station 1 is received by a receiving unit 2, the received broadcast signal is sent to a control unit 3, and video data of the broadcast signal is output from a display unit 4 to a monitor 15. (Displayed), and similarly, the audio data of the broadcast signal is output from the audio unit 17 to the speaker 18. Here, in the specification of the present application, video data and audio data are collectively referred to as "broadcast data".
[0022]
When the user selects (selects and sets) an arbitrary (desired) program preview CM in the displayed broadcast data by an appropriate operation, the user operation is transmitted to the control unit 3 via the input unit 5 and the control unit 3 , The broadcast time (reception time) of the selected program preview CM is held, and from this broadcast time information, the CM broadcast time table (FIG. 5) stored in the database 6 and the program-related information ( Referring to FIG. 6), the information acquisition unit 8 acquires program information (FIG. 7) of a program that has been announced, and acquires program-related information (FIG. 6) stored in the database 6 by the information acquisition unit 8. The program information (FIG. 7) is acquired by the information acquisition unit 8 by referring to the Internet 7 from the acquired information, or the program information is acquired by the information acquisition unit 8 directly from the Internet 7 in the same manner as described above. I do.
[0023]
The acquired program information is sent to the control unit 3, converted into reservation information by the reservation unit 9 and set for reservation. When the reservation is set, the information that the reservation has been set is synthesized by the synthesizing unit 14 under the control of the control unit 3, whereby the display unit 4 causes the monitor 15 to display the character or mark indicating that the reservation has been set ( (See FIG. 4). Then, when the set date and time comes, the recording program records the broadcast program data reserved for recording on the recording medium 11 by the recording unit 10.
[0024]
When the broadcast signal is received by the receiver 2, the program information of the program preview CM is held by adding the time at the time of reception (broadcasting time) to the broadcast data by the controller 3, and the time information at the time of reception is stored. , And is obtained by referring to a CM broadcast time table (FIG. 5) and the like. In addition, the program information may be obtained by using program-related information (FIG. 6) preliminarily added and multiplexed to the broadcast signal.
[0025]
The program information is obtained from the broadcast time information based on a database, the Internet, or the like, but other information may be stored.
[0026]
Next, a description will be given, with reference to FIG. 1, of a recording reservation method in a case where program-related information is added to a broadcast signal in advance when a recording reservation is made from a broadcast program announcement CM.
[0027]
The broadcast signal broadcast from the broadcast station 1 is received by the receiving unit 2, and the program-related information added to the broadcast signal is extracted by the extracting unit 16 from the received broadcast signal. Sent to 3. The received broadcast signal is output (displayed) from the control unit 3 to the video data of the broadcast signal from the display unit 4 to the monitor 15, and similarly, the audio data of the broadcast signal is output from the audio unit 17 to the speaker 18. You.
[0028]
When the user selects (selects and sets) an arbitrary program preview CM in the displayed broadcast data, the CM broadcast time table stored in the database 6 is obtained from the program-related information extracted by the extraction unit 16. With reference to (FIG. 5) and the program-related information (FIG. 6), the program information (FIG. 7) of the program that has been announced is acquired by the information acquisition unit 8, and the program-related information (FIG. 7) stored in the database 6 is acquired. 6) is acquired by the information acquisition unit 8, the program information (FIG. 7) is acquired by the information acquisition unit 8 by referring to the Internet 7 from the acquired information, or directly from the Internet 7 in the same manner as described above. The program information is acquired by the information acquisition unit 8.
[0029]
The obtained program information is sent to the control unit 3, converted into reservation information by the reservation unit 9, and set for reservation. When the reservation is set, information indicating that the reservation has been set is synthesized by the synthesizing unit 14 under the control of the control unit 3, and the display unit 4 displays a character or mark indicating that the reservation has been set on the monitor 15 (see FIG. 4). ). Then, when the set date and time comes, the recording program records the broadcast program data reserved for recording on the recording medium 11 by the recording unit 10.
[0030]
Here, when the broadcast signal from the broadcast station is a digital signal, the control unit 3 of FIG. 1 decodes the video data and the audio data, respectively, and outputs the video data from the display unit 4 to the monitor 15, and outputs the audio data. Is output from the audio unit 17 to the speaker 18. Other than that is the same as described above.
[0031]
In addition, as a method of adding and multiplexing the program-related information to the program broadcast data in advance, as a method of arranging in a frequency gap, multiplexing with a video stream such as MPEG, putting in management information for managing the stream, A method of arranging a dedicated stream is conceivable.
[0032]
Further, as the recording medium 11 in FIG. 1 described above, any one can be adopted as long as it can record data, such as various removable media, a hard disk, a semiconductor memory, and a storage on a network.
[0033]
Further, the program information is acquired based on the extracted program-related information in a database, the Internet, or the like as an example, but other information may be stored.
[0034]
FIG. 2 is a flowchart showing a processing flow in a case where a recording reservation is made from a program preview CM being broadcast in the present embodiment.
[0035]
In this case, first, a program signal is received from a broadcasting station (step S1) and displayed on a screen (step S2). Next, the user selects a notice in the displayed broadcast program or a program notice CM in the CM, and selects whether or not to make a reservation for recording (step S3). When the user does not select the recording reservation, the process ends.
[0036]
When the recording reservation is selected, it is determined whether or not the program-related information is added to the broadcast signal of the selected program preview CM (step S4). If the program-related information is not added to the broadcast signal, control is performed. Based on the broadcast time information of the selected program preview CM held in the unit 3, program information is acquired from an attached database or the Internet or the like (step S6). If program-related information or the like is added to the broadcast signal in advance, the additional information is extracted (step S5), and the program information or the like is obtained from the attached database or the Internet using the extracted information (step S5). S6), a recording reservation is set based on the obtained information (step S7).
[0037]
As described above, when the user selects an arbitrary program preview CM or sets a recording reservation, a TV having a touch panel function on the screen, a dedicated controller, a pen-type input device, a dedicated keyboard, a dedicated keyboard, What is necessary is just to comprise so that a reservation button etc. may be used.
[0038]
A recording reservation method using a reservation button will be described with reference to FIG. As shown in FIG. 4, when the program preview CM is displayed (broadcast) on the monitor 15, when the reservation button 21 is pressed, the above-described processing after the user input is performed, and the display 22 indicating that the reservation is completed is displayed. , On the monitor 15.
[0039]
Here, the data stored in the database 6 is data of a CM broadcast time table (FIG. 5) or data of program-related information such as a broadcasting station or a program production company. When referred to, program information can be obtained.
[0040]
Furthermore, it is more desirable that the data stored in the database 6 be data created for program recording reservation. In addition to the above, any information that can obtain similar contents may be used.
[0041]
For example, a link address to a home page on the Internet that includes the above-described contents may be used (see FIG. 6). In this case, in the configuration of the present embodiment shown in FIG. 1, the information acquisition unit 8 acquires the link address to the Internet homepage stored in the database 6, and refers to the homepage on the Internet 7 from there. The program information is acquired by the information acquisition unit 8.
[0042]
The data stored in the database 6 in advance may be data automatically downloaded from the Internet at a specified date and time (eg, every Monday at 6:00 am), a CD-ROM sold on the shop every week, or the like. The data is always available for purchase downloaded from a storage medium to a recording medium at a convenience store or the like, and is stored in the database 6 from the recording medium. Needless to say, any other storage method may be used as long as new information can always be stored. Alternatively, necessary information may be obtained directly from a broadcast dedicated to CM information, a drive for a recording medium, or the like without referring to the database.
[0043]
Next, in the present embodiment, a case where a recording reservation is made from a program preview CM during reproduction of recorded data will be described with reference to FIG.
[0044]
In this case, any recording data is called from the recording medium 11 by the calling unit 12 (for example, by specifying any recording data from a list of the recording data in the recording medium 11 and called), and via the control unit 3. When a desired program preview CM is reproduced on the monitor 15 from the display unit 4 during reproduction, the user selects (selects and sets) the program reservation CM by an appropriate operation. Thus, the CM broadcast time table (FIG. 5) and the program-related information (FIG. 5) stored in the database 6 via the control unit 3 based on the time information at the time of recording added to the recorded data at the time of recording. Referring to FIG. 6), the program information of the program that has been announced is obtained by the information obtaining unit 8, the program information is obtained from the Internet 7 by the information obtaining unit 8 in the same manner as described above, The program information is acquired from the Internet 7 or the like based on the data acquired by the information acquisition unit 8 with reference to the stored program-related information (FIG. 6) and the like. The acquired program information is sent to the control unit 3, converted into reservation information by the reservation unit 9 and set for reservation. When the reservation is set, information indicating that the reservation has been set is synthesized by the synthesizing unit 14 under the control of the control unit 3, whereby the display unit 4 displays a character or a mark indicating that the reservation has been set on the monitor 15. Then, when the set date and time comes, the recording program records the broadcast program data reserved for recording on the recording medium 11 by the recording unit 10.
[0045]
When program-related information (FIG. 6) or the like is added to the broadcast signal in advance and recorded together with the broadcast program data, the program information is referred to from the database 6 or the Internet 7 from the program-related information in the recorded data. The information is acquired by the information acquiring unit 8. Thereafter, the operation is the same as that described above.
[0046]
Also, in the case of such a recording reservation using the program preview CM during which the recorded data is being reproduced, similarly to the case where the program preview CM being broadcast is reserved for recording, the user can go to the Internet homepage stored in the database 6. May be acquired by the information acquisition unit 8, the homepage is referred to on the Internet 7, and the program information is acquired by the information acquisition unit 8.
[0047]
Here, in the case of the recording reservation using the program preview CM during the reproduction of the recording data, it is conceivable that the program reserved for recording has already been broadcast. In such a case, that is, when the acquired program information includes the past (past) time information, in the present embodiment, the reservation unit 9 determines the time information, and The reservation information of the time information is sent to the search unit 13. In addition, for this time, program information is added to the recorded data when making a reservation for recording the broadcast program data. As described above, when the program information is added to the recorded data, if the program information is searched at the time of the above search, the recorded data can be easily searched from the reservation information.
[0048]
Then, the recording time of the recording data stored in the recording medium 11 is searched, and if the matching data is searched, the program for which the recording reservation is desired has already been broadcasted, but the program is displayed as “Drama It is recorded as "3 of ○○". If no matching data is found, a message such as "The program for which recording reservation is desired has already been broadcast and cannot be recorded." Alternatively, from a place where all or a large number of program data are stored in a server or the like, a search may be performed based on the program information, and arbitrary program data may be downloaded.
[0049]
It should be noted that even when the user has forgotten, but wants to play back the recorded data that has already been broadcast, the user can specify and call the desired recorded data from the list of recorded data in the recording medium 11. Needless to say, the display (reproduction) can be performed on the monitor 15 from the control unit 3 via the display unit 4.
[0050]
FIG. 3 is a flowchart showing a processing flow in the case of making a recording reservation from a recorded program preview CM in the present embodiment.
[0051]
In this case, if there is a program preview CM of an arbitrary program during reproduction of the recorded data (step S11), it is selected whether or not to record the program preview CM (step S12). If no recording is selected, the process ends.
[0052]
If the recording reservation is selected, it is determined whether or not the program-related information is added to the recorded data (step S13). If the program-related information is not added, the broadcast data is reserved for recording. Since the received broadcast time information is recorded together with the broadcast data, program information is acquired from the received broadcast time by referring to an attached database or the Internet (step S15). If program-related information has been added to the broadcast signal in advance, the program-related information added is extracted (step S14), and based on the extracted information, the program information or the like is read from an attached database or the Internet or the like. Obtain (step S15). Next, it is determined from the program information whether the scheduled broadcast time is in the future or in the past (step S16). If the program has not been broadcasted, the recording reservation is set based on the acquired scheduled broadcast time information (step S17). On the other hand, if the program has already been broadcast, the recording medium is searched (step S18), and it is determined whether or not there is recorded data of the corresponding program (step S19). If there is recorded data for the corresponding program, "The program for which recording reservation was requested has already been broadcast, but the program has been recorded as" Drama XX-3 ". Is displayed (step S21), and thereafter, a selection display is made as to whether or not to continue reproduction (step S22). For example, after completion of the reproduction of the currently reproduced program data, a display such as "Do you want to continue the reproduction of" Drama XX-3 "?" Is displayed (step S22), and the process returns to step S11 to have already been broadcast. Plays the recorded broadcast data. After that, it is the same as above.
[0053]
In this way, when a continuous program or the like is reserved for continuous recording, continuous playback can be performed by a simple operation.
[0054]
If there is no recorded data of the program in the process of step S19, a message such as "The program for which recording reservation is desired has already been broadcast and cannot be recorded" is displayed (step S20). Alternatively, from a place where all or a large number of program data are stored in a server or the like, a search may be performed based on the program information, and arbitrary program data may be downloaded.
[0055]
Note that the broadcast program data that has been broadcast and recorded on the recording medium, which is the object of the Yes determination in step S19 described above, is data that the user has manually reserved for recording, and a system that automatically reserves recording from a program preview CM. The recorded data, such as weekly recording reservations and genre recording reservations, are data set by the user and continuously recorded.
[0056]
Alternatively, the data may be data in which all the program preview CMs being broadcast are reserved for automatic recording.
[0057]
Further, when it is assumed that the timing at which the user designates the program preview CM during the playback of the recorded data is always the last of the program being played back, the above-described step S19 makes a YES determination. Alternatively, the recorded data of the searched program may be automatically and immediately reproduced. As described above, when a continuous program or the like is reserved for continuous recording, continuous playback can be performed by a simple operation.
[0058]
Here, when a program is scheduled to be recorded, or when the data of the program is recorded (recorded) on a recording medium by a user's manual operation during the broadcast of the program, the recording / playback apparatus of the present embodiment uses the recorded data. A function of automatically making a recording reservation from all the program preview CMs in the program is also added. The operation when the automatic recording reservation mode is set by this function will be described below.
[0059]
FIG. 9 is a flowchart showing a processing flow when automatically making a reservation from all the program preview CMs in the data recorded on the recording medium in the present embodiment.
[0060]
When broadcast data is recorded on a recording medium by a method such as recording reservation (step S31), it is determined whether program-related information has been added to the recorded broadcast data in advance (step S32).
[0061]
When the program-related information is not added to the recorded broadcast data in advance, the program broadcast time information (which may be the recording start time) and the program broadcast time information which are also recorded together with the recorded broadcast data as described above are used. Originally, CM broadcast time table information that can be obtained by referring to a database and the Internet, and the data reproduction length of recorded broadcast data (or recording end time) are obtained (step S33), and these obtained information are used. Then, all the program preview CMs included in the recorded broadcast data are detected (step S34). Then, the program information of each detected program preview CM is acquired by the above-described method (step S35), and the recording reservation of the program corresponding to all the program preview CMs is set using the acquired program information. (Step S36). Thus, when the set recording reservation date and time comes, broadcast data is recorded on the recording medium based on the recording reservation information.
[0062]
Also, if program-related information is added in advance to the broadcast data recorded on the recording medium, and this added program-related information is also recorded together with the broadcast data, the recording is performed based on the program-related information. All the program preview CMs included in the broadcast data thus detected are detected (step S34). Then, the program information of each detected program preview CM is acquired by the above-described method (step S35), and the recording reservation of the program corresponding to all the program preview CMs is set using the acquired program information. (Step S36). Thus, when the set recording reservation date and time comes, broadcast data is recorded on the recording medium based on the recording reservation information.
[0063]
Here, the process of determining whether or not the program-related information has been added to the broadcast data in step S32 is performed after recording, but the process of determining whether or not the program-related information has been added when receiving the broadcast data is performed. May go.
[0064]
Further, the target to be subjected to the determination process when receiving broadcast data may be all the broadcast data to be received.
[0065]
It should be noted that additional information such as a flag and a marker is added to the data recorded by the automatic recording reservation as described above so that the data can be distinguished from the data set and recorded by the user. . Further, additional information such as a different flag or a marker is added to the broadcast program data recorded on the recording medium other than that recorded by the automatic recording reservation so that the recording method can be distinguished. . Further, priority may be given to the additional information (flag, marker, etc.) that can distinguish such a recording method.
[0066]
In this way, if an automatic recording marker is added, when data is deleted when the capacity of the recording medium approaches the upper limit, the user can designate a recording reservation or manually record a recording. Since the data can be distinguished from the data, it can be easily deleted from the data with the automatic recording marker.
[0067]
Also, by assigning priorities to the additional information (such as flags or marks) added to the recorded data so that the above-described recording methods can be distinguished, data in the recording medium is automatically deleted from the lowest priority. Can be performed. For example, when the recorded capacity of the recording medium exceeds a certain capacity, a deletion method of automatically deleting the time information of the data with the automatic recording marker from the oldest time information can be adopted. The priority may be determined in advance for each type of additional information (flag, marker, etc.) added for each recording method. Such priorities can also be used for processing other than order determination when deleting.
[0068]
For example, the user's favorite information is set in advance, and the information is used to calculate the original importance. If the user sets the preference for "drama", the importance of "drama" is higher than that of "news". In particular, if the user sets "prefers suspense", the preference is higher than "family drama". Is to increase the importance of the “Suspense Theater”.
[0069]
In addition to the above, additional information (flag, marker, etc.) that has been watched is added to recorded data that has been watched by the user at the time of viewing, and the priority can be set to the lowest order. In the case of stopping, additional stop information (flag, marker, etc.) is added to the halfway stop point, or additional information (flag, marker, etc.) of the halfway stop is added to the recording data, and the priority is set higher. May be.
[0070]
Viewed data with additional information can be deleted first when automatically deleted to secure free space on the recording medium.
[0071]
In addition, the data with the additional information on the halfway stop is displayed at the top of the recorded data list when the user tries to play back the recorded data for viewing, and allows the user to recognize that the data has been reproduced halfway, With the additional information added to the halfway stop, replay from the halfway stop is possible.
[0072]
FIG. 8 shows an example in which a marker for each recording method described above is added to the program information of the recorded data. In this case, different markers are added to data recorded by program reservation CM, manual recording reservation, continuous recording, continuous recording, genre recording, and automatic recording to distinguish them.
[0073]
According to this example, “74”, “77”, “79”, and “80” are automatically recorded. Therefore, for example, in the case of automatic deletion, the time information is deleted in the order of "74", "77", "79", and "80" which are older.
[0074]
When a plurality of users make a recording reservation for the same program, only one data is actually reserved for recording, and each piece of reservation information refers to the actually recorded data. As described above, when one piece of recording data is referred to by a plurality of pieces of reservation information, the number of references and the reference source information are counted and stored in each piece of reservation information. When the recorded data is manually deleted, the number of references may be referred to, and the deletion may be performed only when the number of references other than the automatically recorded data is 0.
[0075]
Further, when the preview CM of the same program is included in a plurality of different program data, a plurality of recording reservations may be made for the same program, as described above. In this case, as described above, only one piece of data is actually reserved for recording, and each piece of reservation information refers to data actually reserved for recording.
On the other hand, when deleting the program data of the reference source, the number of references is reduced by one. When the number of references is the last one, the automatic recording data of the reference destination may be deleted together.
[0076]
Here, in the above description, the information added in advance to the broadcast signal is, for example, program-related information. In accordance with that, the data retention expiration date when recording the broadcast program data, Relevant information such as area information of the place where the image was shot, a profile of the person appearing in the broadcast program, information on a product introduced in the broadcast program, and program audience rating acquisition information may be added in advance. Good.
[0077]
If the data retention expiration date is added to the broadcast signal in advance, after the broadcast data is recorded, if the expiration date comes, the recorded data cannot be reproduced or the recorded data is automatically deleted. ,can do.
[0078]
In addition, when information on a region where a broadcast program is shot is added to a broadcast signal, information on the region obtained from the Internet can be simultaneously displayed on a small screen or the like during reproduction after recording the broadcast data, or In response to the request, it is possible to switch the display to the homepage related to the region.
[0079]
Also, when the performer's profile is added to the broadcast signal in advance, when the broadcast data is recorded and played back, if the attached pointer or the like is set to the person, the profile of the person is displayed in a balloon-like form. Becomes possible.
[0080]
In addition, when the product information introduced in the broadcast program is added to the broadcast signal in advance, when the broadcast data is recorded and reproduced, the pointer is attached to the product with an attached pointer or the like, and the detailed description of the product is given. It is possible to refer to images and the like from different angles, and it is also possible to purchase the product on the Internet.
[0081]
Also, when the program audience rating acquisition information is added to the broadcast signal in advance, at the time of reproduction after recording the broadcast data, the program audience rating is acquired from the Internet or the like based on the program audience rating acquisition information. In addition, it is possible to display the broadcast data in accordance with the audience rating during reproduction. Also, the audience rating of each broadcast data is obtained from the Internet or the like based on the program audience rating acquisition information and added to the broadcast data already recorded on the recording medium as additional information, and stored in the recording medium based on this. It is also possible to grasp the importance of the broadcast data in. This importance means that the higher the audience rating, the higher the importance, that is, what many people see is interpreted and set as many people are interested, Also, it is possible to perform prioritization such as when deleting.
[0082]
In addition, the audience rating information may be set on the device side so as to acquire all the recorded audience ratings, instead of acquiring it at the time of reproduction.
[0083]
On the other hand, there is also a problem of what to do if a plurality of programs broadcast at the same time are reserved for recording.
[0084]
With reference to the "chase-and-play function" of the current recording device (a function that allows the program to be immediately reproduced from the scene where the recording was started while recording the program), it is considered that at least two programs can be simultaneously recorded at present. .
[0085]
When there is a restriction that only two programs can be recorded at the same time, there are the following processes, and such a process may be performed. Further, the user may be allowed to select a processing method at that time.
-At the stage where the number of recording reservations exceeds the limit, an error message such as "cannot be reserved because the number of simultaneous recording reservations is exceeded" is displayed on the monitor and recording reservation is not performed.
-When the number of recording reservations exceeds the number, the recording reservation is made to a separately set server, and the recording is automatically or arbitrarily downloaded.
-In order to increase the number of recordable reservations, it is possible to select a lower recording rate (by lowering the recording rate, the image quality is degraded but the number of simultaneous recordings is considered to increase).
[0086]
Here, a method of referring to the program information (FIG. 7) and the program-related information (FIG. 6) in the present embodiment will be described with reference to FIGS.
[0087]
Any program preview CM in the program being broadcast or being reproduced, for example, in the drama “Time Traveler” (see 91 in FIG. 7) broadcast from 21:00 on June 6, 2002, It is assumed that the next announcement CM (see 35 in FIG. 5) of the drama being broadcast at 21:53:00 is selected and set. This selection setting operation is performed, for example, by pressing the reservation button (21 in FIG. 4) when the next preview CM of the above drama is displayed on the monitor (15 in FIG. 1).
[0088]
When the reservation button (21 in FIG. 4) is pressed, the current time counted by the counter in the control unit (3 in FIG. 1) (in this case, the time between 21: 53: 0 and 21:53:59) Is held in the control unit (3 in FIG. 1). Then, based on the held time information, the CM broadcast time table (FIG. 5) stored in the database (6 in FIG. 1) is referred to. Referring to 21:53:00 on June 6, 2002 in FIG. 5, it is “drama next notice”, and the program information indicated by the next drama notice is “102” in FIG. When a recording reservation is set in the reservation section (9 in FIG. 1) based on the program name, start date and time, end date and time, and channel number of the program information ("102" in FIG. 7), the completion of the reservation is displayed on the monitor (15 in FIG. 1). ) (For example, display 22 in FIG. 4).
[0089]
If the program-related information (FIG. 6) is added to the broadcast signal being received (or the broadcast data being reproduced), for example, the program-related information in FIG. The homepage address "is extracted by the extraction unit (16 in FIG. 1), the program information (7 in FIG. 7) is referred to via the control unit (3 in FIG. 1) and the Internet (7 in FIG. 1) based on the extracted information. “102”). On the basis of the acquired program information, the reservation unit (9 in FIG. 1) sets a recording reservation.
[0090]
The CM broadcast time table will be described with reference to FIG. 5, which is an example of a time table including CMs at 21:00 on a certain day.
[0091]
First, the spot CM 31 of the company flows from 21:00: 00, and thereafter, the program 32 starts from 21:00: 00. Another spot CM 31 flows between programs, and among them, program preview CMs 33 and 34 of different programs also flow. At the end of the program, the next notice 35 of the program flows from 21:53:00, and the next program notice 36 also flows between the subsequent spot CMs 31.
[0092]
The “program announcement CM” used for the program recording reservation in the present embodiment indicates 33, 34, 35, and 36.
[0093]
In FIG. 6, which is an example of the program-related information, a homepage address list of a site where the program information is stored is stored. Based on this, it accesses the Internet and acquires program information.
[0094]
FIG. 7, which is an example of program information, includes information on a program name, a start date and time, an end date and time, and a channel number. The reservation can be set from the information.
[0095]
Alternatively, a reservation may be set based on information obtained by combining a CM broadcast time table (see FIG. 5) and program information (see FIG. 7).
[0096]
Note that the processing functions of the recording / reproducing apparatus of the present embodiment described above are carried by a program for realizing such processing functions. It goes without saying that the program may be a computer-readable recording medium storing the program.
[0097]
In the present invention, unlike a server or the like which records and stores all broadcasts for 24 hours, a program designated by the user is reserved for recording. By doing so, it is considered that scheduled recording closer to the user's preference is possible. This is because it is highly possible that the program preview CM is also a program preview CM related to the main broadcast even in the automatic reservation from the program preview CM in the recorded data. By doing so, it is possible to reduce waste of recording program data that the user does not want.
[0098]
【The invention's effect】
As described above, according to the present invention, it is possible to reserve recording of a program for which a CM has been announced by a simple operation from a program announcement CM being broadcast and being reproduced. Therefore, while viewing the broadcast video or the recorded video, the user can make a reservation for recording the program that the user wants to record by a simple operation, so that the user's trouble in making the recording reservation can be reduced, and the viewing of the recorded video can be reduced. Since the recording reservation can be made during the recording, the convenience for the user is greatly improved, and the usability is also improved.
[0099]
Also, when a recording reservation is made from a program preview CM being reproduced, if the program has already been broadcast, but is stored as recorded data on a recording medium, the program retrieved from the stored recorded data Can be easily and easily reproduced.
[0100]
In addition, since it is possible to make a recording reservation from all the program preview CMs in the data to be recorded, it is possible to prevent the user from missing a desired program and to increase user satisfaction.
[0101]
Further, since it is possible to add a marker to the recording data for each recording method, it is possible to easily select (for example, automatically delete) the recording data stored in the recording medium.
