In the program data transfer management table, a transfer flag is set for each transfer requirement such as the present invention, alternative, emergency, and manual. The transfer flag manages whether or not program data transfer has occurred for each transfer requirement.

The transfer flags of the present invention and the alternative are set to indicate that the transfer of the program data has occurred, for example, a predetermined time before the broadcast start time (for example, 12 hours before). Further, the transfer flags of the present invention and the alternative are set so as to indicate that the transfer of the program data has not occurred when the broadcast end time has elapsed. For example, in the program data transfer management table shown in FIG. 2, "○" is set in the transfer flag when the transfer of program data occurs, and "す る と" in the transfer flag is deleted when the broadcast end time has elapsed. The emergency and manual transfer flags are set to “番 組” immediately after the emergency and manual contents are registered because the broadcast start time of the emergency and manual program data is undecided.

For example, when securing redundancy for a predetermined time (24 hours), program data that is likely to start broadcasting within 24 hours from the present is transferred from the program data server 11 to the transmission device 12a. The current time is midnight on January 1.
In some cases, the information management apparatus 10 selects the program data A, B, C, and D of the present invention as the program data having a high priority.

After creating the program data transfer management table corresponding to the program data A, B, C, and D, the information management apparatus 10 transfers the program data A, B, C, and D from the program data server 11 to the transmission apparatus 12a. Forward. Similarly, the information management device 10 creates or updates a program data transfer management table corresponding to the alternative program data B and E, the emergency program data Z, and the manual program data X, and then creates the program data E, Z, X
From the program data server 11 to the transmission device 12a. Since the program data B has already been transferred from the program data server 11 to the transmitting device 12a as the program data of the present invention, only the transfer flag of the alternative is managed and the program data B is not transferred.

Accordingly, as shown in FIG. 4, program data A, B, C,
D, E, Z, and X are stored. in this way,
The memory of the transmission device 12a does not store duplicate program data, and the data capacity can be used effectively.

The memory of the sending device 12a is as follows.
The present invention is configured to have an area for storing program data of the present invention, and alternative, emergency, and manual areas for storing alternative, emergency, and manual program data other than the present invention. Although the present invention area and the alternative, emergency, and manual areas can be changed as appropriate, the minimum secure area of the present invention is set so that the present invention area does not become smaller than a predetermined data capacity. In this embodiment, 1
A minimum reserved area of the present invention for storing two hours of program data is set.

Next, referring to FIG. 3, a description will be given of the processing in the case where the program data a, b, and d are inserted in the idle time of the present invention, and the program data F is inserted after the alternative program data E. FIG. 5 is a diagram illustrating another example of the program data that may be transmitted from the transmission device. FIG.
FIG. 4 shows another example of a diagram for explaining a memory included in the transmission device.

In FIG. 5, for example, program data a, A, B, C, b, D, and d are set as the program data of the present invention. Program data B, E, F as alternative program data
Is set. Program data Z is set as urgent program data. Program data X is set as manual program data.

Assuming that the current time is midnight on January 1, the information management apparatus 10 selects the program data a, A, B, C, b, D, and d of the present invention as the program data having a high priority. I do. Then, the information management device 10 stores the program data a,
After creating program data transfer management tables corresponding to A, B, C, b, D, and d, program data a, A, B, C, b,
D and d are transferred from the program data server 11 to the transmission device 12a. At this time, the 24-hour data capacity of the transmission device 12a is filled with the program data of the present invention.

Assuming that alternative program data B, E, F, emergency program data Z, and manual program data X occur after the program data of the present invention has been transferred to the transmitting device 12a, the information management device 10 Select the program data Z and X of
A program data transfer management table corresponding to the program data Z, X is created. Then, the information management device 10 transmits the program data a, A, B,
The program data D and d having low priority among C, b, D and d are deleted, and the program data Z and X are transferred from the program data server 11 to the transmission device 12a.

Next, the information management apparatus 10 selects alternative program data B, E, and F, and creates or updates a program data transfer management table corresponding to the program data B, E, and F. Then, the information management device 10 deletes the low-priority program data C, b among the program data a, A, B, C, b, Z, X stored in the transmission device 12a, and deletes the program data E, F is transferred from the program data server 11 to the transmission device 12a. Since the program data B has already been transferred from the program data server 11 to the transmitting device 12a as the program data of the present invention, only the transfer flag of the alternative is managed and the program data B is not transferred.

It is assumed that the priority of the program data of the present case and the alternative is higher in the order of earlier broadcast start time. Also,
Since the transmission device 12a has a minimum secure area for storing the program data of the present invention, the program data stored in the minimum secure area of the present invention has the highest priority among the program data of the present invention.

When the program data is deleted from the transmitting device 12a due to the low priority, the information management device 10 sets the presence or absence of the transfer in the program data transfer management table to "none" as necessary. For example, when erasing the program data d of the present invention of FIG. Even if the program data d of the present invention is deleted, if the program data d is transferred as alternative, emergency, or manual program data,
The presence or absence of the transfer in the program data transfer management table corresponding to the program data d is set to “Yes”.

For the program data deleted from the transmission device 12a because of its low priority, the program data with high priority becomes unnecessary. Will be transferred.
Therefore, it is possible to always transfer the program data having the highest priority to the transmission device 12a. As described above, the memory of the transmission device 12a can flexibly store the high-priority program data of the present, alternative, emergency, and manual program data, and efficiently transfer the program data. Is possible.

[0045]

As described above, according to the present invention, it is necessary to provide an emergency area or a manual area in the transmission apparatus in case of transmitting emergency or manual program data with a high transfer priority, for example. Therefore, the data capacity of the transmission device can be effectively used. In addition, since program data having a high transfer priority is transferred to the transmission device, it is possible to transfer the program data efficiently. As a result, the data capacity of the memory included in the sending device can be reduced.

Further, according to the present invention, program data having a high transfer priority can be selected in accordance with, for example, transfer requirements such as the present invention, alternatives, emergency and manual, and a broadcast start time. Further, by registering transferred information indicating that the selected program data has been transferred to the transmitting device, it is possible to avoid duplicate transfer.

Further, according to the present invention, if program data having a higher transfer priority than the program data transferred to the transmission device is stored in the program data server later, the transfer of the program data transferred to the transmission device is performed. The program data having a low priority is temporarily deleted. Therefore, even if the high-priority program data is later stored in the program data server, the high-priority program data can be transferred from the program data server to the transmission device.

Further, according to the present invention, among the program data transferred to the sending device, the program data transferred to the sending device such that the regular program data for which the broadcast time is set, such as the present invention, does not become shorter than a predetermined time. Can be erased.

Therefore, for example, when there is no alternative, emergency, or manual program data, the program data of the present invention can be transferred to the full data capacity of the transmission device, and alternative, emergency, or manual program data is generated. It is possible to delete the program data of the present invention which is being transferred to the transmitting device at a point in time so that the program data does not become shorter than a predetermined time.
