This process is mainly executed by the message extracting unit 16 at predetermined intervals. First, the message extracting unit 16 selects any one of the areas where the broadcast program targeted for the bulletin board as the content is broadcast (step S201).

When a region is selected, the message extracting unit 16
Retrieves one message in order from among the messages recorded in the message database 15 (step S202). Then, by comparing the net broadcast time associated with the retrieved message with the net broadcast time from the start of broadcasting in the selected area measured by the time measuring unit 14, the net broadcast time before the net broadcast time in the area is compared. It is determined whether or not the broadcast time is associated with the message, that is, whether or not the extracted message has been broadcasted in the area (step S2).
03).

If the message has already been broadcast in the area, the message extracting unit 16 selects the extracted message as a message to be provided in a bulletin board as content (hereinafter referred to as a provided message) ( Step S204). Then, step S2
Proceed to 05. On the other hand, if the broadcast has not been broadcasted in the area, the process proceeds to step S2.
Proceed to 05.

In step S205, the message extracting unit 16 stores the message in the message database 15 in step S205.
At 202, it is determined whether there are any messages that have not been retrieved. If there is a message that has not been retrieved, the message to be retrieved is set as the next message in the message database 15 (step S206), and the process returns to step S202.

On the other hand, if no unretrieved message remains, the message extracting unit 16 proceeds to step S20 for the area selected in step S201.
All the provided messages selected in 4 are sorted according to the associated broadcast time stored. Then, a bulletin board including the sorted provided messages is created as content provided for the area (step S207).

Further, the message extracting unit 16 determines whether or not there is an area which has not been selected in step S201 among the areas where the broadcast program targeted for the bulletin board as the content is broadcast (step S201). Step S
208). If there is an unselected area, the area to be selected in step S201 is set as the next area (step S209), and the process returns to step S201.

When there are no unselected areas, the message extracting unit 16 passes the contents of the bulletin board including the provided message created for each area in step S207 to the communication processing unit 18. Then, the communication processing unit 18 transmits the contents of the bulletin board created for each region to the terminal device 2 in each region according to the determination result of the terminal region determination unit 17 (step S21).
0). Then, the process of this flowchart ends.

In the terminal device 2, when the communication processing unit 25 receives the contents of the bulletin board sent from the server device 1, it displays this on the display unit 22. In addition, the display unit 22 displays the broadcast program received by the broadcast program receiving unit 21 according to the tag attached to the content (however, when the broadcast time is in the area). The audio output unit 23 outputs the audio of the broadcast program. This allows
While viewing the broadcast program, the user of the terminal device 2 can refer to the message displayed on the bulletin board for the broadcast program.

The operation of the message providing system according to this embodiment will be described below based on a specific example. Here, it is assumed that the same inference drama is broadcast as a television program in two regions A and B. However, area A
Is a broadcast start time of 7:00 pm (19:00) on October 1, 2000, and a broadcast start time in an area B is 8:00 pm (20:00) of October 2, 2000. . 5 (A-1) to (A-4) show display states on the display unit 22 of the terminal device 2 located in the area A. FIGS. 5 (B-1) to (B-4) show 5 shows a display state on the display unit 22 of the terminal device 2 located in the area B. In the following description, it is assumed that communication delay in the Internet 3 and processing waiting time in the server device 1 are ignored.

At 19:16 on October 1, in the area A, as shown in FIG.
Is being broadcast. The user of the terminal device 2 located in the area A inputs a message “I think the criminal is A child” from the input unit 24, and the net broadcast time from the start of the broadcast is 1
This message is transmitted to the server device 1 at the time when the time reaches 3 minutes and 22 seconds. As a result, in the message database 15, a message “I think the culprit is A child” is recorded in association with the net broadcast time of 13 minutes 22 seconds. Here, if the server device 1 has not received a message from another terminal device 2, there is no message displayed on the bulletin board.

Next, at 19:58 on October 1, in the area A, as shown in FIG.
The broadcast of all programs has ended. At this time, the display unit 22 of the terminal device 2 located in the area A is displayed
A bulletin board including a message “I think the culprit is A child” transmitted at 16:00 is displayed. Also, the user of the terminal device 2 inputs a message “it was a great trick” and sends it to the server device 1. As a result, in the message database 15, the message "It was a great trick" is recorded in association with the net broadcast time (broadcast end).

Next, at 20:15 on October 2, in the area B, as shown in FIG.
Scene 3 is being broadcast. At this time, it is assumed that the net broadcast time from the start of broadcasting in the area B is 11 minutes and 17 seconds. The message "I think the culprit is A-child" and the message "It was a great trick" are already recorded in the message database 15, but since the net broadcast time is later than 11 minutes 17 seconds, At this time, it is not selected as a message to be provided to the terminal device 2 in the area B.

Next, at 20:21 on October 2, in the area B, as shown in FIG.
Scene 5 is being broadcast. At this time, it is assumed that the net broadcast time from the start of broadcasting in the area B is 15:00 seconds. Here, among the messages recorded in the message database 15, the net broadcast time associated with the message “I think the culprit is A child” is the area B.
This message is also selected as a message to be provided to the terminal device 2 in the region B because the broadcast time is earlier than the net broadcast time measured by the time measuring unit 14 for the broadcast of the terminal B in the region B. 22 is displayed.

Next, at 20:30 on October 2, in the area B, as shown in FIG.
Scene 8 is being broadcast. At this time, it is assumed that the net broadcast time from the start of broadcasting in the area B is 21 minutes 41 seconds. Also in this case, the display unit 22 is
Then, a bulletin board containing a message "I think the culprit is A child" and not containing a message "It was a great trick" is displayed. Also, at this timing,
The user of the terminal device 2 in the area B says, "The culprit is B
It is. Is input and transmitted to the server device 1. As a result, in the message database 15, the message “The perpetrator is still B.” is recorded in association with the net broadcast time of 21 minutes and 41 seconds.

On the other hand, in the terminal device 2 in the area A, at 20:29 on October 2 before the message “The perpetrator is still B.” is transmitted from the terminal device 2 in the area B, FIG. As shown in (A-3), the display unit 22
In the bulletin board displayed in the "Criminal is still B
It is. Is not included. However, at 20:32 after the message “The perpetrator is still B.” was transmitted, as shown in FIG.
The content of the provided bulletin board is updated and displayed on the display unit 22 of the terminal device 2 in the area A.

Further, at 20:57 on October 2, the broadcasting of all the contents ends in the area B as shown in FIG. 5 (B-4). At this time, in the message database 15, a message "I think the culprit is A child", a message "It was a great trick", and a message "The culprit is after all B" are recorded. At this point, since all the contents are broadcast in the region B, all the recorded messages are selected as the messages to be provided to the terminal device 2 in the region B, and are displayed on the display unit 22 of the terminal device 2 in the region B. Will be displayed.

As described above, according to the message providing system of this embodiment, the time measurement unit 14
Measures the net broadcast time from the start of broadcast of a broadcast program in each region. The message sent from the terminal device 2 is recorded in the message database 15 in association with the net broadcast time from the start of broadcasting in the area where the terminal device 2 is located. Then, the message extracting unit 16 selects only messages that have passed the net broadcast time for each region as messages to be included in the contents of the bulletin board provided to each region. As a result, messages about content that has not yet aired in the area
The message is not sent to the terminal device 2 and the message is provided on the bulletin board, so that the interest in the unbroadcast content is not lost.

The messages extracted by the message extracting unit 16 from the message database 15 are sorted according to the net broadcast time, so that the user of the terminal device 2 views the messages on the bulletin board in a substantial time order corresponding to the broadcast. It becomes possible. Furthermore, since the net broadcast time of the message sent from the area where the broadcast of all contents has ended is uniformly recorded as information indicating the end of the broadcast,
When a broadcast program ends in a later aired area,
All messages will be immediately visible.

The present invention is not limited to the above embodiment,
Various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.
