The recording reservation application 14 (more specifically, a processor that operates according to a program such as a CPU provided in the mobile phone 1) obtains status from the recording management server 3 via the mobile phone network 2 via the communication control unit 13. A request message is transmitted (step S2). The status acquisition request message is information for requesting acquisition of information (such as information indicating reservation status or recording status) indicating the state of the user B who is the user of the mobile phone 1 in the system. User B's subscriber number is included.

  The recording management server 3 that has received the status acquisition request message from the mobile phone 1 first authenticates the user B who is the user of the mobile phone 1 that is the transmission source, based on the subscriber number included in the status acquisition request message. (Step S3). For example, the recording management server 3 confirms whether the subscriber number included in the status acquisition request message is registered in the reserved recording status data database managed by the recording management server 3. It authenticates that the user B who is the user of the mobile phone 1 is a user who has a usage contract with this system.

  When the user B, who is the user of the mobile phone 1 that is the transmission source of the status acquisition request message, is authenticated as a user who has subscribed to this system, the recording management server 3 is registered in the database. Information indicating the state in this system is extracted from the reserved recording status data of the user. For example, information on a reserved (including recorded) television program (hereinafter referred to as reservation information) is extracted. Then, a status acquisition response message including the extracted reservation information is sent to the mobile phone 1 of user B (step S4).

  When the mobile phone 1 receives the status acquisition response message, the recording reservation application 14 displays an EPG display screen reflecting the reservation information included in the status acquisition response message (step S5). FIG. 8 is an explanatory diagram showing an example of an EPG display screen in which reservation information is reflected. As shown in FIG. 8, the recording reservation application may generate an EPG display screen showing a list of TV programs of each broadcasting station for each time period and display the EPG display screen on the display unit 12. In the EPG display screen, when a TV program for which reservation has been completed is included in the TV program being presented, the column presenting information on the TV program is different from the other columns. It may be reflected by presenting in the color. When a recorded television program is included, the column presenting information on the television program may be displayed in a different color. In the example shown in FIG. 8, the TV program column for which reservation has been completed is displayed with shading. After the reservation information is reflected, the recording reservation application waits for an instruction from the user.

  Here, the user B performs an operation of selecting a television program to be reserved for recording on the EPG display screen. For example, according to information input from the key input unit 11 by a user operation, the recording reservation application selects a TV program that the user (user B) wants to make a recording reservation from among the TV programs presented on the EPG display screen. Determine (step S6). Here, it is assumed that a TV program of AM11: 0 to PM10: 00 of broadcasting station A has been determined. The recording reservation application 14 presents information on the TV program selected by the user on the EPG display screen and confirms that the recording reservation is to be made, and then sends a recording reservation request message including the program information to the recording management server. 3 (step S7).

  FIG. 9 is an explanatory diagram illustrating an example of an EPG display screen when confirmation of recording reservation determination is performed. As shown in FIG. 9, the recording reservation application 14 presents information on the program while indicating that the column presenting information on the TV program selected by the user is selected on the EPG display screen. A confirmation message for recording reservation may be presented.

  The recording management server 3 that has received the recording reservation request message from the mobile phone 1 determines the reservation status included in the reserved recording status data of the user B registered in the database based on the program information included in the recording reservation request message. The information shown is updated (step S8). Then, the recording management server 3 sends a recording reservation response message for notifying that the reservation has been reflected in the database of the recording management server 3 to the mobile phone 1 that is the transmission source (step S9).

  When the mobile phone 1 receives the recording reservation response message, the recording reservation application 14 receives the notification and displays an EPG display screen reflecting the completion of the reservation (step S10). FIG. 10 is an explanatory diagram showing an example of an EPG display screen after setting a recording reservation. In FIG. 10, it is shown that the column presenting the information of the TV program AM11: 0 to PM1: 0 of the broadcasting station A is displayed in a color indicating reservation (shaded in FIG. 10). ing.

  Next, an operation when recording a television program for which recording has been reserved will be described. FIG. 11 is a sequence diagram showing an example of a recording operation of a reserved television program in the present system.

  The recording management server 3 detects whether or not the TV program reserved by each user has reached the start time based on the reserved recording status data of each user registered in the database (step S11). For example, when reflecting the recording reservation in the database, the recording management server 3 activates a timer that times out several minutes before the program start time, and detects that the start time has been reached by detecting the timeout of the timer. May be. Or, it is detected that the start time has come by referring to the scheduled recording status data of each user periodically to determine whether the current time is several minutes before the start time of the reserved TV program May be.

  When the recording management server 3 detects that the TV program reserved by a certain user (user B in this case) has reached the start time, the recording management instruction message specifying the TV program and the user to start recording. Is sent to the program recording server 5 (step S12). Note that the recording management server 3 may specify a hard disk area allocated to the user instead of specifying the user. Further, an identification number for identifying the television program may be added between the recording management server 3 and the program recording server 5 for a later termination instruction.

  When receiving the recording start instruction message from the recording management server 3, the program recording server 5 starts recording the designated television program through the broadcast receiving unit 4 (step S13). The program is recorded by recording it in a free area of the hard disk area 52 (here, the hard disk area 52-B) assigned to the designated user.

  Thereafter, the recording management server 3 detects whether or not the TV program reserved by each user has reached the end time based on the reserved recording status data of each user registered in the database (step S14). For example, when the recording management server 3 detects the start time of a reserved television program, the recording management server 3 starts a timer that times out at the end of the broadcast time of the television program and detects the timeout of the timer to reach the start time. May be detected. Alternatively, even if it is detected that the end time has been reached by managing information on the TV program being recorded and determining whether the current time has passed the end time of the TV program currently being recorded. Good.

  When the recording management server 3 detects that the TV program reserved by a certain user (user B in this case) has reached the start time, the recording management instruction message specifying the TV program and the user to end recording Is sent to the program recording server 5 (step S15). Note that the identification number added at the start instruction may be specified instead of the TV program to be recorded and the user specified.

  When receiving the recording end instruction message from the recording management server 3, the program recording server 5 ends the recording of the designated program (step S16). The program recording server 5 stops storing the broadcast data in the hard disk area 52 assigned to the designated user. Then, in order to notify the recording management server 3 of the end of recording and information of the stored broadcast data (for example, information on the storage destination hard disk area and file name), a recording completion notification message is transmitted (step S17).

  Receiving the recording completion notification message, the recording management server 3 confirms that the series of processing (steps S12 to S18) related to the recording has been completed without any problem, and reserve recording of the corresponding user in the database of the recording management server 3 The contents of the situation data are updated (step S18). For example, the recording management server 3 updates the contents of the reserved recording status data of the corresponding user in the database of the recording management server 3 based on the broadcast data information included in the recording completion notification message. Here, the information indicating the recording status may be updated to add information on the program recorded this time, or to reduce the remaining recordable time.

  In addition, the recording management server 3 generates a recording destination URL for notification to the mobile phone 1 (for example, a URL to a reproduction site provided by the program reproduction server 7 designating a recording location of the broadcast data of the program). (Step S19). The recording management server 3 that has generated the recording destination URL then sends a recording completion notification mail creation instruction message for instructing the mobile phone 1 to create a recording completion notification mail to the mail server 6 (step S20). . In the recording completion notification mail creation instruction message, for example, information of the program to be notified, the generated notification destination URL, and the mail address of the mobile phone 1 as the mail transmission destination are designated.

  The mail server 6 that has received the recording completion notification mail creation instruction message from the recording management server 3 creates a recording completion notification mail including the program information specified in the notification content and the recording destination URL, and is sent to the specified mail address. (Step S21). The recording management server 3 may generate the mail, specify the mail, and issue a transmission instruction to the mail server 6. For recorded programs, the information of the recording destination URL is added and notified,

  The recording management server 3 transmits a status update notification message to the mobile phone 1 when it is connected to the recording reservation application 14 of the mobile phone 1 when the database is updated in step S18. It may be. In the mobile phone 1 that has received the status update notification message, the recording reservation application 14 updates the display of the EPG display screen based on the information about the reserved (including recorded) TV program included in the status update notification message. do it. FIG. 12 is an explanatory diagram illustrating an example of an EPG display screen in which reservation information is reflected. In the example shown in FIG. 12, the EPG display screen of the mobile phone 1 shows an example in which the recording completion of the TV program of AM9: 0 to AM10: 00 of the broadcasting station A is reflected. In addition, for a recorded program, information on the recording destination URL is added and notified, and when the television program is selected on the EPG display screen, the recording destination URL is automatically accessed. May be.

  Next, an operation when viewing a program recorded on the mobile phone 1 will be described. In response to a user operation, the mobile phone 1 accesses the recording destination URL by selecting a recording destination URL described in the reservation completion notification email or determining a recorded program on the EPG display screen. The recording destination URL is a URL to a reproduction site provided by the program reproduction server 7, and the URL includes designation of broadcast data of the recorded program being presented.

  When the program playback server 7 detects access to the recording destination URL, the program playback server 7 makes a request to read the designated broadcast data to the program recording server 5. Then, after the read broadcast data is converted in accordance with the capability of the mobile phone 1 that is the access source, for example, HTML-format image data including the converted broadcast data as moving image content is returned.
