The operation of the distributed CM bank system according to one embodiment of the present invention will be described with reference to FIGS.

In the small CM filing systems 1 to 3 of the agents A to C, material codes are first issued to CM materials. An example of this numbering method is shown in FIGS.
It is shown in (c).

Each of the agents A to C has an agent code (N
o. ) Is assigned (step S1 in FIG. 7). The agency code is assigned to be unique for each company. For example, the agent "company A" has the agent code "1000", the agent "company B" has the agent code "1001", the agent "company C" has the agent code "1002", “1003” is assigned to the agency “Company D” as the agency code (see FIG. 6A).

Material codes that are unique are issued at each of the agents A to C (steps S2 and S2 in FIG. 7).
3). Material code is agency code + material No. Are used. For example, in the case of the agency "Company A", "Material 1"
"1000 0001" as a material code in "material 2", "1000 0002" as a material code in "material 2",
"Material 3" as material code "1000 0003"
However, “Material 4” has “1000 000” as the material code.
4 "is assigned [see FIG. 6 (b)].

In the case of the agency "Company B", "Material 1"
“1001 000A” as a material code, “1001 000B” as a material code in “material 2”,
"Material 3" as material code "1001 000C"
However, “material 4” has “1001 000” as the material code.
D "are respectively assigned [see FIG. 6 (c)].

The number of digits of a code to be used, usable characters, and information contents need to be unified as a whole and unique. For the issued data, data for which a CM transmission contract has been made is tabulated for each broadcast station, and the ATM-LAN network 4
Is transmitted to the DS (data server) 8 of the broadcasting stations A to C via the.

The contents of work performed by the small CM filing systems 1 to 3 of the agents A to C are three types of filing functions, filing PV functions, and material code numbering functions as shown in FIG. That is, the small CM filing systems 1 to 3 are responsible for the filing part of the conventional CM bank system.

According to the issued code, VDT
13 is operated and CM material is HDD / solid-state memory 15b
Filed in At the time of filing, the data is recorded in a compression format such as MPEG by the encoder 15a. A preview operation is performed to check whether there is any abnormality in the filed material (step S in FIG. 7).
4, S5). If it is NG, filing is performed again.

In DS8 of broadcasting stations A to C, agency A
OA data is created based on the material codes received from the broadcast stations A to C, and sent to the CM buffering systems 5 to 7 of the broadcasting stations A to C (steps S11 to S in FIG.
13).

Broadcasting station A CM buffering system 5
7 receive the OA data from the DS 8 (step S21 in FIG. 7), and request the small CM filing systems 1 to 3 of the agents A to C to transmit the material necessary for the OA data (see FIG. 7). FIG. 7 step S22).

The small CM filing systems 1-3 are C
The material requested by the M buffering systems 5 to 7 is transmitted (buffering) via the ATM-LAN line network 4 in the form of data such as MPEG (step S6 in FIG. 7). This means that the data recorded in the small CM filing systems 1 to 3 has been copied to the CM buffering systems 5 to 7 (step S23 in FIG. 7).

The CM buffering systems 5 to 7 are APs
When an OA instruction is received from the S (automatic program control device) 9 (step S31 in FIG. 7), the copied data is modulated into baseband by the decoder 53b and then transmitted to the OA (step S24 in FIG. 7).

As described above, by performing the filing work and the preview work in the small CM filing systems 1 to 3 of the agencies A to C, the confirmation work at each broadcasting station becomes unnecessary, and the work efficiency can be improved. it can.

Further, since distribution can be made from the small CM filing systems 1 to 3 of one agency A to C to a plurality of broadcasting stations A to C, materials of the same quality can be supplied. Since transmission and reception are performed not as baseband but as data, stable quality can be maintained.

Further, since the high-speed ATM-LAN network 4 is used, even if the contents of the material are changed due to the influence of the weather or the incident, each agent side A to C carries in just before the OA transmission. And changes are possible. Furthermore, the numbering of the material code is performed by the small CM filing system 1 of the agents A to C.
, The broadcast stations A to C do not need to perform material management.

In the above description, OA transmission is performed after modulation to baseband by the decoder 53b. However, it is also possible to pass compressed data as it is through the master system and decode it before the transmitter. In this case, more stable quality can be maintained. However, this method requires a response from the master system.

[0040]

As described above, according to the present invention, C
By filing the CM material and confirming the CM material on the creator side of the M material in a distributed manner, and transmitting the CM material on the broadcast station side, the work efficiency up to OA transmission can be improved. effective.
