Description

  The present invention relates to a content reservation technique in a content recording apparatus, and more particularly to a technique for managing reservation and reproduction by a plurality of users without greatly changing the mechanism of an existing content recording apparatus.

  A situation in which electrical devices in the house are connected to a network is being realized. Newly released devices are being equipped with a network link function as standard. As a result, it is becoming an environment where users can easily use contents or services (hereinafter simply referred to as “services”) without being aware of the location. Under such an environment, the user is approaching the day when the user can use the service he / she uses from any terminal regardless of location and time.

  On the other hand, such networking and so-called cloud computing are progressing. With these developments, the world in which the number of services that users can handle via the network dramatically increases. Such a world is a so-called “super-distribution” world.

  The super-distribution world seems convenient at first glance. However, there is a concern that it may be difficult for users to fully enjoy such a world. For example, it may be difficult for the user to determine which service or the like should be used. Even if the service to be used can be determined, there is a risk that a complicated operation may be forced to use the service.

  Service providers that provide such services also have circumstances that require users to perform some operations. For example, as long as services are provided, service providers need to authenticate users. Therefore, the service provider issues an identification number (ID) and / or password (PW) for each user (hereinafter, these are simply referred to as “ID / PW”). The user inputs such ID / PW when logging in to the service or the like. The service provider determines a service to be provided according to the input ID / PW.

  Usually, the ID / PW is issued by the service provider when the user uses a specific service for the first time, and is registered in the service user authentication system of the service provider. There are systems in which the user determines the ID / PW, but such a system requires that the user IDs do not overlap each other.

  As is well known, there are many services for authenticating a user by such ID / PW. Some of these services are very important for life. Moreover, the number of such services is increasing rapidly. A user who uses a plurality of services or the like needs to learn ID / PW for each service. As the number of ID / PWs to remember increases, it becomes difficult to store them without error. Although it is possible to use a common ID / PW, it is dangerous. It is even more dangerous to record ID / PW as a memo. Therefore, it is desired to solve these problems.

  As one solution to such a problem, a standard called OpenID has been proposed and realized. Refer to URL = http: //openid.net/. Between services complying with this specification, services on various WEB sites that require authentication can be used with one ID / PW registered with an OpenID service provider. However, it is necessary to store ID / PW separately for a WEB site that does not use the OpenID service.

  On the other hand, in a personal computer (hereinafter referred to as “PC”) or the like, as a function of an operating system (hereinafter referred to as “OS”), a technique for authenticating a user by ID / PW is adopted as in the Internet service. By using the result of the user authentication, various menus and functions different depending on the user can be provided. For example, the desktop environment, e-mail settings, WEB browser bookmarks, and the like differ depending on the user. By authenticating a user with ID / PW, a service based on such personal information can be provided on the same PC.

  When managing PCs in a network, a system that manages them centrally by ID / PW is widely used. A user can log on to any computer in the same network with the same ID / PW.

  In recent years, DVD (Digital Versatile Disc) / HDD (Hard Disk Drive) recorders and BD (Blu-Ray Disc) recorders are rapidly spreading. These are mainly intended for recording television (hereinafter referred to as “TV”) programs. These products are basically used to make a reservation for recording a program by connecting to a TV receiver. Therefore, these products are likely to be shared by families.

  In such a recorder, in general, a reservation list that lists recording reservations and a recording list that lists recorded programs can be viewed. One such list exists for each recorder. Therefore, for example, programs reserved by a plurality of users separately in the same reservation list are displayed together. The same applies to the recording list.

  However, users are only interested in the programs they want to watch. Therefore, there is a desire to manage the reservation list and the recording list for each user.

  In order to solve such a problem, it is conceivable that each user logs in to the recorder using a unique ID as in the case of a PC. However, in general, the recorder is operated by a remote controller. Compared with a PC keyboard, the remote control is not suitable for the operation of inputting ID / PW. Therefore, it is not desirable for the recorder to use the same ID / PW as the PC. In the first place, it is necessary to drastically change the structure of existing recorders simply by introducing the multi-user concept into the recorder. There is also a problem that data must be managed separately for each user. Further, there is a problem that the user who uses the recorder has to log off and log on each time. As a result, the operation of the recorder becomes complicated.

  In order to solve this problem, it has been proposed to operate the recorder with a mobile phone instead of the attached remote controller. For example, Patent Document 1 discloses a mobile phone that functions as an input device to a TV receiver. This mobile phone receives an inputable character string type (name, phone number, etc.) from the TV receiver. Further, the input character string that matches the received character string type is returned to the TV receiver. This character string can be used to log in to a service or the like via a TV receiver.

  However, such a mechanism does not exist at all in the conventional recorder. Developing such a new function just for logging in to the recorder is not cost effective.

In step 484, the reservation list 170 managed by the mobile phone 112 is compared with the received recording list, and the programs in the reservation list 170 of the mobile phone 112 are extracted from the recording list from the recording / playback device 106. Step 484 and step 486 displaying information about the extracted program recording as a recording list.

  FIG. 17 shows an example of the recording list screen 540 displayed at step 486. Referring to FIG. 17, on the recording list screen 540, a list of programs reserved on the mobile phone 112 extracted from the reservation / recording list 220 of the recording / playback device 106 as described above, and playback Button 544 is displayed. Although a delete button is also displayed in FIG. 17, this will be described in the recorded program deletion process. For example, when the user selects the program 542 and presses the play button 544, an instruction for playing the program 542 is transmitted to the recording / playback device 106.

  Therefore, referring to FIG. 15 again, in step 488, a process for causing the user to select a desired one from the recording list is performed. In the subsequent step 500, a playback instruction relating to the selected program is created and transmitted to the recording / playback device 106. The recording / playback device 106 starts playback of the program selected in step 488 based on this playback instruction. A program of the recording / playback device 106 for realizing program playback will be described later. The format of the playback instruction information transmitted from the mobile phone 112 to the recording / playback device 106 is the same as the reservation information 350 shown in FIG. 10 and the reservation deletion information 460 shown in FIG. However, only the control command is replaced with one indicating reproduction.

<Recording deletion process>
Referring to FIG. 18, the program for realizing the recording erasure process (step 250 in FIG. 6) includes steps 570, 572, 574, and 576 that perform the same processes as steps 480, 482, 484, and 486 in FIG. Step 578 for allowing the user to select a program to be erased from the displayed recording list, Step 580 for displaying a confirmation screen for recording erasure and confirming the user for erasing the recording, and selection in Step 580 And step 582 for creating recording-erased program information corresponding to the programmed program.

  FIG. 19 shows an example of the recording list screen 600 displayed on the display unit 156 of the mobile phone 112 in step 576. In the recording list screen 600, information related to programs in the reservation list 170 of the mobile phone 112 is extracted from the recording list transmitted from the recording / playback device 106 and displayed as a list. For example, when the user selects the program 602 from this list and presses the delete button 604, the processing in step 578 is terminated.

  FIG. 20 shows an example of the program deletion screen 630 displayed at step 580 at this time. Referring to FIG. 20, detailed information on a program to be recorded and a delete execution button 632 are displayed on program delete screen 630. When the user presses erasure execution button 632, the process in step 580 is terminated, and the processes in and after step 582 are executed.

  FIG. 21 shows an example of the recording deletion program information 660 created in step 582 of FIG. The format of the recording deletion program information 660 is also the same as the reservation information 350 shown in FIG. 10, the reservation deletion information 460 shown in FIG. However, only the control command is different, and the command is “M-DEL”. As will be described later, the recording / playback device 106 that has received the recording erased program information 660 updates the recording information of the program specified by the recording erased program information 660. As a result, the recording list screen of the mobile phone 112 becomes a recording list screen 680 shown in FIG. As can be easily understood by comparing the recording list screen 680 shown in FIG. 22 with the recording list screen 600 shown in FIG. 19, the program (program 602 in FIG. 19) indicated by the recording deletion program information 660 has been deleted.

  Referring to FIG. 18, after step 582, mobile phone 112 executes step 586 of waiting for reservation deletion acceptance information transmitted from recording / playback device 106. When the reservation deletion acceptance information is received, the mobile phone 112 reflects the deletion of the corresponding reservation in the reservation list held by the mobile phone 112 in step 588 and ends the process.

[Program Configuration of Recording / Playback Device 106]
<Overall control>
Referring to FIG. 23, the program for controlling the entire recording / playback device 106 waits until it receives some control signal from the input unit 212 or the remote control signal receiving unit 216 (see FIG. 3). When any control signal is received at 700, the reservation instruction process (step 704), the reservation release process (step 706), the reproduction process (step 708), and the recorded program erasure depend on what the control signal is. Step 702 that executes any one of the processing (Step 710) and other processing (Step 712) and returns control to Step 700 is included.

<Reservation instruction processing>
A program for realizing step 704 (reservation instruction processing) in FIG. 23 has the following control structure with reference to FIG. In step 740, the received reservation information is retrieved. An example of the reservation information taken out at this time is shown by reservation information 770 in FIG. The reservation information 770 is created from the reservation information 350 shown in FIG.

  Subsequently, based on the retrieved reservation information 770, it is determined whether or not an entry of reservation information relating to the program already exists in the reservation / recording list 220 (step 742). If so, control proceeds to step 746 (described below). If there is still no reservation information entry for the program in the reservation / recording list 220, the entry is created in the reservation / recording list 220. At this time, 0 is assigned to the “reservation count” as an initial value. Blanks (null) are substituted as initial values in the “thumbnail” and “moving image location” fields. In this embodiment, if these fields are blank (null), this indicates that the program has not yet been recorded. When the recording of the program is completed, information indicating the storage location of the thumbnail image indicating the content of the program and the storage location of the moving image data (content data) are stored in these.

  Subsequently, in step 746, 1 is added to the value of “reservation count” of the entry corresponding to the reservation information 770 in the reservation / recording list 220, and the reservation / recording list 220 is updated to complete the reservation processing ( Step 748). In step 750, the reservation acceptance information is transmitted to the mobile phone 112, and the process ends. In step 748 and step 750, for example, with reference to FIG. 26, the recording / playback device 106 displays a message 790 indicating that the recording reservation has been accepted on the screen of the display unit 210.

<Reservation deletion process>
Referring to FIG. 27, the program for realizing the reservation deletion process executed in step 706 of FIG. 23 extracts the reservation deletion information 840 as shown in FIG. 28 from the reservation deletion information 460 received from the mobile phone 112. 810 and the step of determining whether or not the reservation number of the reservation information related to the program specified by the extracted reservation deletion information 840 is “2” or more, thereby determining whether or not the reservation related to the program is duplicated. 812.

  If the determination in step 812 is negative (ie, if there is only one recording reservation for the same program), the reservation information entry for that program is deleted from the reservation / recording list 220 in step 814. If the determination in step 812 is affirmative (that is, if there are two or more recording reservations for the same program), in step 816, the value of “reservation count” is set to 1 in the entry of that program in the reservation / recording list 220. Subtract. After steps 814 and 816, control proceeds to step 818, and a message indicating that the reservation deletion has been accepted is displayed on display unit 210. After step 818, a message indicating that the reservation deletion acceptance has been completed is transmitted to the mobile phone 112, and the process ends.

  An example of the screen displayed on the display unit 210 in step 818 is shown in FIG. Referring to FIG. 29, on this screen, a message 860 indicating that the reservation deleted program is specified and the reservation deletion is accepted is displayed on the screen.

  According to the above processing, after all, the count value of the reservation command received by the recording / playback device 106 is correctly stored in the “reservation count” column of each program entry, including the number of reservation deletions. become.

<Regeneration>
A control structure of a program for realizing the reproduction process executed in step 708 of FIG. 23 will be described with reference to FIG. This process is started when a recording list transmission request is received from the mobile phone 112. That is, in step 880, the recording list is transmitted to the mobile phone 112. The recording list can be created by extracting the reservation / recording list 220 whose moving image location value is not blank. At this time, the recording / playback device 106 creates a recording list from the reservation / recording list 220 and transmits it regardless of which mobile phone has sent the recording list transmission request. Extracting only those related to each mobile phone from the recording list is work on the mobile phone side.

  In step 882, the system waits until a program playback instruction is received from the mobile phone 112. The program playback instruction includes information for identifying a specific program (combination of broadcast time, channel, etc.) based on information in the reservation / recording list 220 of the recording / playback device 106, and this program is played back by the recording / playback device 106. It is an instruction requesting to do. When the recording / playback device 106 receives this program playback instruction, the recording / playback device 106 reads the content data of the designated program from 204 and gives it to the data processing unit 202 to start playback. As a result, as shown in FIG. 31, the video of the designated program is displayed on the display unit 210 of the recording / playback device 106, and the sound is played back.

<Recorded program deletion process>
The control structure of the program for realizing the recorded program erasure process executed in step 710 of FIG. 23 will be described with reference to FIG. First, in step 910, the recording deletion program information 940 as shown in FIG. 33 is extracted from the recording deletion information received from the mobile phone 112 (recording deletion program information 660 in FIG. 21). In step 912, it is determined whether or not the value of “reservation count” of the entry corresponding to the recording erased program information 940 recorded in the reservation / recording list 220 is “2” or more. This determination relates to whether or not recording reservations for the same program have been made by two or more mobile phones.

  If the determination in step 912 is negative, in step 914, the recording data (content data) of the program specified by the recording deletion program information 940 is deleted from the storage unit 204, and an entry corresponding to the program is set in the reservation / recording list. Delete from 220. If the determination in step 912 is affirmative, in step 916, the reservation / recording list 220 is updated by subtracting 1 from the “reservation count” value of the entry corresponding to the program in the reservation / recording list 220.

  In either case after steps 914 and 916, a message indicating that the deletion of the designated program has been completed is displayed on the display unit 210 in step 918. In the subsequent step 920, the reception information for deleting the recorded program (information indicating that the deletion of the specified recorded program has been completed) is transmitted to the mobile phone 112, and the process ends.

  FIG. 34 shows an example of the message 960 displayed on the display unit 210 of the recording / playback device 106 in step 918 of FIG. Referring to FIG. 34, in the present embodiment, message 960 indicating that the recording erasure has been executed is displayed together with information for identifying the program whose recording has been erased.

[Operation]
Each part of the recording reservation system 100 operates as follows. In the following description, it is assumed that, in the mobile phone group 108, the recording / reproduction device 106 is instructed by the mobile phone 112 to reserve recording, delete reservation, play back, and delete the recorded program.

<Recording reservation>
In this case, the cellular phone 112 executes the processing of steps 240, 242, and 244 in FIG. Further, in step 244, referring to FIG. 7, first, the processes of steps 270, 272, 274, and 276 are executed. As a result of the processing in step 276, the program reservation information 350 (FIG. 10) is transmitted to the recording / playback device 106. In response to this, the recording / playback device 106 executes the processing of steps 700, 702, and 704 in FIG.

  In step 704, the recording / playback device 106 has the following two operations depending on the case. That is, (1) when the recording reservation of the designated program is the first time, and (2) when the second time or later.

  In the first case, within step 704, reservation information 770 (see FIG. 25) is extracted from reservation information 350 at step 740 of FIG. Furthermore, an entry of this program is created in the reservation / recording list 220 through the steps 742, 744, and 746. At this time, the “reservation count” is 1.

  In the second case, the route of steps 740, 742, and 746 of FIG. As a result, for example, when the value of the recording reservation count of the designated program is “1”, it becomes “2”, and when it is “2”, it becomes “3”, and so on.

  In either case, the recording / playback device 106 further executes the processing of steps 748 and 750, displays the screen shown in FIG. 26, and returns to step 700 of FIG. In the mobile phone 112, the processing of step 278 and step 280 is executed. Thereafter, control returns to step 240 in FIG. As a result of the processing in step 280, an entry corresponding to the program for which reservation has been completed is created in the reservation list 170 (see FIG. 4) of the mobile phone 112.

  For example, it is assumed that the reservation list 170 of the mobile phone 112 is as shown in FIG. 35 and the reservation list 980 corresponding to the reservation list 170 of the mobile phone 114 is as shown in FIG. Furthermore, it is assumed that the state of the reservation / recording list 220 of the recording / playback device 106 is as shown in FIG.

  In this state, it is assumed that reservation information 1000 as shown in FIG. 38 is transmitted to the recording / playback device 106 by a reservation operation on the mobile phone 112. From the reservation information 1000, reservation information 1020 shown in FIG. 39 is extracted. This program is not reserved in the reservation / recording list 220. Then, the recording / playback device 106 newly creates a program entry corresponding to the reservation information 1020 in the reservation / recording list 220. The value of the number of reservations is “1”. As a result, the state of the reservation / recording list 220 of the recording / playback device 106 is as shown in FIG. When FIG. 41 is compared with FIG. 37, an entry of a program “sports A” broadcast on 8 channels from 21:00 to 22:54 on March 25, 2010 is newly created. The value of the “reservation count” is 1. At this time, an entry corresponding to this program is also created in the reservation list 170 of the mobile phone 112. The reservation list 170 at that time is shown in FIG. In the reservation list 170 shown in FIG. 40, an entry corresponding to the sport A is newly created from the state of FIG.

  Here, it is assumed that there is a recording reservation for “movie B” in FIG. 53 from the mobile phone 114. Then, in the recording / playback device 106, the route of steps 740, 742, and 746 in FIG. 24 is selected, and 1 is added to the value of the “number of reservations” column of “movie B”. That is, although the value of the number of reservations of “movie B” in FIG. 41 is 1, as shown in FIG. 43, the number of reservations of this program is updated to “2”. Also in the reservation list 980 of the mobile phone 114, a movie B entry is newly added as shown in FIG.

<Recording reservation deletion process>
In this case, the cellular phone 112 executes the processes of steps 240, 242 and 246 in FIG. Furthermore, in step 246, referring to FIG. 11, the processes of steps 370, 372, 374 and 376 are executed. In step 376, the reservation deletion information 460 shown in FIG. 14 is transmitted to the recording / playback device 106. In response to this, the recording / playback device 106 executes the processing of steps 700, 702 and 706 in FIG.

  In step 706, the recording / playback device 106 has the following two operations depending on circumstances. That is, (1) for the program designated to delete the recording reservation, the value of “number of reservations” is 1, and (2) when the value is “2” or more.

  In the first case, the route of steps 810, 812, and 814 shown in FIG. 27 is selected. That is, the entry related to the reservation of the designated program is deleted from the reservation / recording list 220. On the other hand, in the second case, the route of steps 810, 812, and 816 shown in FIG. 27 is selected. In this case, the entry related to the reservation of the designated program in the reservation / recording list 220 is not deleted. Instead, 1 is subtracted from the “number of reservations” column.

  Changes in the state of the reservation / recording list 220 at this time will be described with reference to FIGS. Here, it is assumed that an instruction to delete the reservation for movie B is issued on mobile phone 112. At this time, for example, the recording reservation deletion information 1040 shown in FIG. 44 is transmitted from the mobile phone 112 to the recording / playback device 106. The recording / playback device 106 extracts the recording reservation deletion information 1060 shown in FIG. 45 from the recording reservation deletion information 1040. The recording / playback device 106 performs processing for canceling the reserved recording of “movie B” in the reservation / recording list 220 based on the recording reservation deletion information 1060. However, in the processing at this time, as shown in FIG. 43, the value of “number of reservations” of “movie B” is 2. Therefore, the route of steps 810, 812 and 816 in FIG. 27 is selected. Therefore, the entry of “movie B” in the reservation / recording list 220 is not deleted, and the value of “number of reservations” is simply subtracted by one. The state is shown in FIG. Comparing FIG. 46 with FIG. 43, it can be seen that the value of “number of reservations” of “movie B” is subtracted by 1 from “2” to “1”.

  On the other hand, the mobile phone 112 receives a message from the recording / playback device 106 indicating that the reception of the reserved recording of “Movie B” has been completed. Therefore, as shown in FIG. 47, the entry of “movie B” is deleted from the reservation list 170.

<Playback processing>
In the reproduction process, the mobile phone 112 selects the route of steps 240, 242, and 248 in FIG. In step 248, the process of step 480 shown in FIG. 15 is first executed, and the process waits until a recording list is received from the recording / playback device 106. On the other hand, the recording / playback device 106 executes the processing of steps 700, 702 and 708 in FIG. Inside step 708, the process of step 880 shown in FIG. 30 is executed. That is, only entries whose thumbnail and moving image location values are not blank (null) are extracted from the reservation / recording list 220 and transmitted to the mobile phone 112 as a recording list. Thereafter, the recording / playback device 106 executes the processing of step 882. That is, it waits until a playback instruction specifying a program is received from the mobile phone 112.

  On the other hand, in the mobile phone 112 that has received the recording list, the reproduction instruction relating to the program selected by the user is transmitted to the recording / reproduction device 106 through the steps 484, 486, 488 and 500 in FIG. The recording / playback device 106 that has received this playback instruction executes the processing of step 884 in FIG. That is, the content data of the program specified by the playback instruction received from the mobile phone 112 is read from the storage unit 204 and given to the data processing unit 202 to start playback.

  When the reproduction of the content data is completed, the recording / reproducing device 106 returns to the state of waiting for reception of the control signal again in step 700 of FIG.

<Recorded program deletion process>
When the user wants to delete the recorded program, the mobile phone 112 and the recording / playback device 106 operate as follows. Referring to FIG. 6, mobile phone 112 selects the route of steps 240, 242 and 250. Inside step 250, the mobile phone 112 executes the processes of steps 570, 572, 574, and 576 of FIG. As a result, the recording deletion program information 660 as shown in FIG. 21 is transmitted from the mobile phone 112 to the recording / playback device 106.

  The recording / playback device 106 that has received the recording erased program information 660 operates as follows. That is, the recording / playback device 106 selects and executes the route of steps 700, 702, and 710 shown in FIG. Inside step 710, the processing of steps 910 and 912 is executed. Here, the operation of the recording / reproducing device 106 is divided into two types depending on circumstances. (1) In the reservation / recording list 220, the value of the “reservation count” column of the entry of the program designated to be deleted is “1”, and (2) the value is 2 or more.

  In the first case, the recording / playback device 106 selects the route of steps 912, 914, and 916 in FIG. That is, the thumbnail and content data of the designated program are deleted, and the corresponding entry in the reservation / recording list 220 is deleted. In the second case, they are not erased. Instead, 1 is subtracted from the value of the “number of reservations” in the entry corresponding to the program designated to be deleted in the reservation / recording list 220.

  That is, the recording / playback device 106 does not immediately delete the content data or the like when the deletion of the recorded program is designated. As a result of the above processing, if the value of “reservation count” in the reservation / recording list 220 is 1 or more, the content data and thumbnail are left, and the value of “reservation count” in the corresponding entry of the reservation / recording list 220 is only 1. Subtract. If the number of reservations of a program designated to be erased is “1”, it will be 0 if 1 is subtracted from the number of reservations. In such a case, the recording / playback device 106 deletes the thumbnail and content data of the recorded program, and also deletes the corresponding entry in the reservation / recording list 220.

  A specific example of the above processing will be described with reference to FIGS. FIG. 48 shows a state in which all the recording reservations shown in FIG. 46 have been recorded. In FIG. 48, the “reservation count” of news D is 0, indicating that recording of this program has failed for some reason. As described above, the entry whose reservation count is 0 may be deleted from the reservation / recording list 220 at some timing, or after confirming with the user whether or not it can be deleted. When the recording list is transmitted from the recording / playback device 106 for each of the mobile phones 112, 114, 116, etc., it is desirable to delete the program whose reservation count is 0 from the reservation list on each mobile phone.

  FIG. 49 shows the state of the reservation list 170 of the mobile phone 112 when the reservation / recording list 220 of the recording / playback device 106 is in the state shown in FIG. In this state, it is assumed that the user instructs the recording / reproducing device 106 to delete the recording of the drama C from the mobile phone 112. Then, the recording deletion information 1080 shown in FIG. 50 is transmitted from the mobile phone 112 to the recording / playback device 106. The recording / playback device 106 extracts the recording deletion information 1100 shown in FIG. 51 from the recording deletion information 1080. The recording / playback device 106 performs a recording deletion process for drama C according to the recording deletion information 1100.

  Specifically, as shown in FIG. 48, the number of reservations of the recording / playback device 106 is “2”. Therefore, in this case, the recording / playback device 106 does not immediately delete “Drama C”. The recording / playback device 106 decrements the value of “reservation count” of “drama C” in the reservation / recording list 220 by one. FIG. 52 shows the reservation / recording list 220 obtained as a result. As shown in FIG. 52, the number of reservations for drama C has changed from “2” in FIG. 48 to “1”.

  In this state, it is further assumed that the user of the mobile phone 114 instructs to delete the recording of the drama C. Information similar to the recording deletion information 1080 shown in FIG. 50 is transmitted from the mobile phone 114 to the recording / playback device 106. The recording / playback device 106 also extracts recording erasure information similar to the recording erasure information 1100 shown in FIG. 51 from the recording erasure information 1080. The recording / playback device 106 further executes a recording deletion process for drama C according to the recording deletion information. However, this time, in the reservation / recording list 220, the value of the “number of reservations” for the drama C is “1”. When 1 is subtracted from this value, it is “0”. Accordingly, the recording / playback device 106 does not simply subtract the “reservation count” value of drama C in the reservation / recording list 220. Instead, the recording / playback device 106 deletes the content data of drama C from the storage unit 204. Further, the recording / reproducing device 106 deletes the entry of the drama C from the reservation / recording list 220. As a result, the reservation / recording list 220 is in the state shown in FIG.

  Referring to FIG. 53, as a result of the recording erasure process, the entry of drama C is completely erased from reservation / recording list 220.

  As described above, according to the recording reservation system 100 according to the present embodiment, it is possible to instruct recording reservation, reservation cancellation, reproduction, recording deletion, and the like for the same recording / playback device 106 from a plurality of mobile phones. . The recording / playback device 106 manages recording reservations and the like using a common reservation / recording list 220 for all mobile phones. The content data of the recorded program is stored in the storage unit 204 in common. As a result, the recording / playback device 106 can reduce the storage capacity as compared with the case where the recording reservation is managed separately for each user. Each mobile phone can perform only the processing related to the recording reservation instructed to the recording / playback device 106 using the mobile phone. The recording reservation can be managed as if the recording / reproducing device 106 manages the recording reservation separately for each mobile phone. There is no need for the user to manage his / her ID / PW.

  In the above embodiment, the recording reservation is managed for each mobile phone. If a plurality of users use the same mobile phone in common, recording reservations by the users are mixed with each other. Today, however, mobile phones are virtually private and are rarely shared. Therefore, according to the above-described embodiment, it is possible to manage recording reservations for each individual using the same recording / playback device 106.

  In the recording / playback device 106, in addition to conventional information for managing recording reservations, a function for managing the number of reservations for each program may be added. There is no need for individual authentication. Therefore, it is possible to substantially manage the recording reservation for each individual without significantly changing the mechanism of the recording / playback device 106. Whether or not recording reservations by one user are duplicated may be performed by the mobile phone 112. The recording / playback device 106 does not require special processing for checking the overlap of recording reservations for each user.

[Modification]
In the above embodiment, the reservation / recording list 220 serves as both a recording reservation list and a recording list. However, the present invention is not limited to such an embodiment. A recording reservation list and a recording list may be provided separately. In that case, a recording reservation is executed, and each time recording is completed, a record having the same format as the reservation / recording list 220 may be added to the recording list. Recording reservation is managed in the recording reservation list, and recording erasure is managed in the recording list. It will be apparent to those skilled in the art that the program for realizing the processing can be realized in substantially the same manner as that according to the embodiment of the present invention described above.

  In the above embodiment, each mobile phone has the ability to acquire an EPG. However, the present invention is not limited to such an embodiment. The recording / playback device 106 may acquire the EPG and transmit it to the mobile phone by infrared communication.

  In the above embodiment, a mobile phone is used as a remote controller for operating the recording / playback device 106. However, the present invention is not limited to such an embodiment. For example, a PDA (Personal Digital Assistant) or a personal computer (PC) may be used. In addition, an electronic dictionary, an electronic book browsing device, or the like that has the same function as a PDA and can perform infrared communication may be used. Among these, those having a function of accessing various resources on the Internet through a cellular phone network or WiFi are more preferable.

  In the above embodiment, a TV program broadcast by a specific medium called broadcast radio waves has been described as an example. However, the present invention is not limited to such an embodiment. The present invention can be applied to any system as long as it reserves recording of content broadcasted through a specific medium according to a predetermined schedule. A system that only records, not records, may be used.

  In the above system, the recording / playback device 106 plays back a recorded program using its own display unit 210. However, the present invention is not limited to such an embodiment. For example, when the recording / playback device 106 receives a playback instruction for a recorded program, a system may be used in which the played content is transmitted to the mobile phone 112 or the like without being played by itself. In such a system, the input unit 160 does not necessarily require a display device such as the display unit 210. Instead of this, a content data transmission command may be implemented separately from the reproduction command.

  The embodiment disclosed herein is merely an example, and the present invention is not limited to the above-described embodiment. The scope of the present invention is indicated by each claim of the claims after taking into account the description of the detailed description of the invention, and all modifications within the meaning and scope equivalent to the wording described therein are included.
