[Program Guide Distribution Process of Management Computer 10]
First, the program guide distribution process executed by the management computer 10 will be described with reference to FIG. The program guide distribution process is started after receiving a program guide distribution request from the user terminal 20.

  First, the management computer 10 reads a program guide composed of a broadcast program of the time when the program guide distribution request is received and one hour before and after (s51). In this processing, a list of broadcast programs in which a broadcast time is taken on the vertical axis and a broadcast channel is taken on the horizontal axis and a plurality of broadcast program display areas are arranged in a grid is read.

  Next, the management computer 10 identifies the broadcast program reserved for recording among all the broadcast programs constituting the program guide read in the process of s51 (s52). In this process, a broadcast program reserved for recording is specified using a recorded program database. In the recorded program database, program codes assigned to broadcast programs reserved for recording are registered. Therefore, among all the broadcast programs constituting the program guide, a broadcast program whose assigned program code matches the program code in the recorded program database is specified as the broadcast program reserved for recording.

  Next, the management computer 10 identifies a broadcast program that has been recorded (hereinafter referred to as a recorded program) from the broadcast programs identified in the process of s52 (s53). Also in this process, a recorded program is specified using the recorded program database. In the recorded program database, not only program codes but also recording state flags are registered. This recording state flag is set to “0” if the broadcast end time has not passed, and is set to “1” if the broadcast end time has passed. Therefore, a broadcast program whose recording state flag corresponding to the assigned program code is “1” among the broadcast programs specified in the process of s52 is specified as a recorded program.

  Next, the management computer 10 adds a download button b1 to the display area of the program guide corresponding to the recorded program specified in the process of s53 (s54). This download button b1 is used when requesting distribution of program data from the user side terminal 20 in the program guide operation process described later.

  Next, the management computer 10 adds a recording request button b4 to the display area of the program guide corresponding to the broadcast program whose broadcast end time has not passed (s55). The recording request button b4 is used when a user terminal 20 requests recording of a broadcast program in a program guide operation process described later.

Thus, the program guide to which the download button b1 and the recording request button b4 are added is created (see FIG. 10).

In this processing, a program guide in which display areas of a plurality of programs are arranged in a grid pattern with the broadcast time on the vertical axis and the broadcast channel on the horizontal axis is displayed. A download button b1 is added to some of the display areas of the broadcast programs whose broadcast end time has passed among the display areas of the programs constituting the program guide. In addition, a recording request button b4 is added to the display area of the broadcast program whose broadcast end time has not passed among the display areas constituting the program guide. Thus, after the program guide is displayed on the display 25, the user can perform an operation of selecting the download button b1 or the recording request button b4 added to each display area constituting the program guide. . At this time, the user can also execute an operation for ending the program guide operation process (for example, an operation for ending the web browser, an operation for ending the operation of the user terminal 20 itself, or the like). .

  Next, the user terminal 20 stands by until an input operation is executed (s63: NO). In this process, the user terminal 20 executes an operation for selecting the download button b1 or the recording request button b4 added to the program guide or an operation for ending this program guide operation process. stand by.

  When an input operation is executed in the process of s63 (s63: YES), if this input operation is an operation of selecting the download button b1 (s64: YES), the user terminal 20 sends the distribution request data. It transmits to the management computer 10 (s65). This distribution request data is data for requesting distribution of the program data of the corresponding broadcast program, and is data composed of a program code assigned to the broadcast program in the display area to which the download button b1 is added. . Program data is distributed from the management computer 10 that has received the distribution request data.

  Then, the user terminal 20 receives the program data distributed from the management computer 10 (s66). Thus, the program data distributed from the management computer 10 is stored in the HD 24.

  When the input operation performed in the process of s63 is an operation for selecting the recording request button b4 (s64: NO, s67: YES), the user side terminal 20 transmits the recording request data to the management computer 10. (S68). This recording request data is data for requesting recording of the corresponding broadcast program, and is data that can specify the broadcast program in the display area to which the recording request button b4 is added. The management computer 10 that has received the recording request data reserves recording of the broadcast program specified by the recording request data, and registers the program code assigned to the broadcast program specified by the recording request data in the recorded program database.

Thus, after performing the process of s66 or the process of s68, the process returns to the process of s63.
When the input operation executed in the process of s63 is an operation for ending the program guide operation process (s64: NO, s67: NO), the program guide operation process is ended.

[Program Data Distribution Process of Management Computer 10]
Next, program data distribution processing executed by the management computer 10 will be described with reference to FIG. This program data distribution process is started after receiving the distribution request data transmitted by the user terminal 20 in the process of s65 in FIG.

Then, when the user operating the user side terminal 20 performs an operation of selecting the download button b1 added to the program guide, the program data of the broadcast program corresponding to the download button b1 is used. It is distributed to the person side terminal 20. Therefore, the user can easily obtain the program data simply by executing the operation of selecting the download button b1 added to the program guide by the user side terminal 20.

  Furthermore, the management computer can record the broadcast program requested to be recorded from the user side terminal 20, and the program data of the broadcast program thus recorded can be distributed from the management computer 10 to the user side terminal 20. Therefore, the broadcast program can be recorded by the management computer 10 even if the user terminal 20 is not equipped with an apparatus for receiving a broadcast program such as a TV tuner, an apparatus for recording the broadcast program, or application software. The user can obtain program data of the broadcast program thus recorded.

[Modification]
As mentioned above, although embodiment of this invention was described, this invention is not limited to said specific one Embodiment, In addition, it can implement with a various form.

  For example, the management computer 10 is registered from the user terminal 20 before distributing the program guide so that only the users who have registered as members in advance can use the program data distribution systems 1 and 2 in the above embodiment. What is necessary is just to comprise so that the data for authenticating that it is a user may be transmitted.

  In the first and second embodiments, when the program guide distributed by the management computer 10 is a terrestrial broadcast such as a television broadcast, the user operating the user side terminal 20 has a plurality of broadcast regions (the same It may be configured such that the distribution of a program guide in a desired broadcasting area can be requested from among the broadcasting areas). If comprised in this way, the user who uses the user side terminal 20 can receive the delivery of the list | wrist of the broadcast program in the broadcast area different from the broadcast area where he lives. Therefore, when a recorded program (broadcast program to which the download button b1 is added) that the user wants to watch is included in the list of broadcast programs in such a broadcast region, the user can record the recorded program. It is possible to obtain program data of finished programs. Furthermore, in the first embodiment, by using the recording request button b3 added to the program guide, it is possible to request recording of a broadcast program that cannot be recorded because it is different from the broadcast area where the user resides. it can.

  In the first embodiment, the process of s13 in FIG. 3 and the process of s53 in FIG. 9 in the second embodiment are exemplified to specify a recorded program. When a program is specified, a broadcast program that has not been recorded at the same time (hereinafter referred to as a reserved program) is specified, and in the program guide display area corresponding to the reserved program, a recording reservation is being made. A message to that effect may be added. If comprised in this way, the user who uses the user side terminal 20 can receive delivery of the broadcast program scheduled to be recorded by the other user side terminal 20, ie, program data after that. Can be confirmed in advance.

  In the first embodiment, an example is shown in which the reservation end data for notifying the management computer 10 that the setting related to the recording reservation is completed is transmitted in the process of s33 in FIG. did. However, the user-side terminal 20 transmits data for notifying that the recording reservation is ended to the management computer 10 when the recording of the broadcast program is actually ended, not the setting related to the recording reservation. It may be configured. If comprised in this way, it can notify reliably that the recording of the broadcast program was complete | finished. Furthermore, since it is possible to notify the end of recording, it is not necessary to prepare a recording state flag in the recorded program database of the management computer 10, so that the data amount as the recorded program database can be reduced.

  In the first embodiment, when a plurality of transfer source terminals 20b are specified in the process of s41 in FIG. 6, the management computer 10 selects at random among the plurality of transfer source terminals 20b in the process of s42. The transmission request data is transmitted to the one transfer source terminal 20b. However, when a plurality of transfer source terminals 20b are specified in the process of s41 in FIG. 6, it is preferable to perform the following process before transmitting the transmission request data in the process of s42. First, the management computer 10 sequentially checks whether or not each of the plurality of transfer source terminals 20b specified in the process of s42 can transmit program data. Here, for example, confirmation data for confirming whether the transfer source terminal 20b is connected to the Internet 30, whether the transfer source terminal 20b is activated, or whether the program data has been deleted is transmitted. . If the program data can be transmitted from the transfer source terminal 20b that has received the confirmation data, transmittable data is transmitted. On the other hand, if the program data cannot be transmitted, data that cannot be transmitted is transmitted, or data is not transmitted within a predetermined time. Then, the management computer 10 transmits the transmission request data to the transfer source terminal 20b that has transmitted the transmittable data first in the process of s42. If comprised in this way, transmission request data can be transmitted only to the transfer origin terminal 20b which can transmit program data from the some transfer origin terminal 20b.

  In the first and second embodiments, the management computer 10 and the user side terminal 20 are illustrated as being connected via the Internet 30, but the management computer 10 and the user side terminal 20 are, for example, It may be connected via a network such as a LAN.

  The program data distributed to the user side terminal 20 (transfer destination terminal 20a) in the process of s46 in FIG. 6 of the first embodiment and the process of s72 in FIG. It may be configured such that a broadcast program based on the above cannot be played after a predetermined number of playbacks or after a predetermined playback period (time, number of days).

  Specifically, first, the management computer 10 is configured to distribute program data to which data that can specify the reproduction period or the number of reproductions is added. Then, after the user terminal 20 receiving this program data has passed the playback period specified by the data added to the program data or the playback period of the broadcast program based on the program data, or the number of playbacks After reaching, the broadcast program based on this program data may not be reproduced, or the program data itself may be deleted.

  In addition, the management computer 10 adds a program that operates after the broadcast program playback period based on the program data has passed the predetermined playback period or after the broadcast program playback count reaches the predetermined playback count. The program data may be distributed, and the user terminal 20 in which the program is operated may be configured not to reproduce the broadcast program based on the program data or to delete the program data itself.

  With this configuration, various services can be provided to the administrator side who manages the management computer 10 and the user side who uses the user side terminal 20. For example, the management computer 10 distributes the program data in which the reproduction period or the number of reproductions is “0” based on the added data, that is, the broadcast data based on the program data cannot be reproduced. By executing this input operation, the added data becomes invalid and the broadcast program can be reproduced. Then, the administrator who manages the management computer 10 distributes the above-mentioned password for a predetermined fee to the user who uses the user-side terminal 20, so that the collected fee is recorded with the administrator on the broadcast program. It is possible to provide a service such as distributing to the user side who performed the service.
