, A mother file 7 and a sending buffer 8.

An operation terminal 1 is a terminal for a user to input a command for editing, a mother CPU 2 is a CPU for controlling recording and reproduction on a mother file 7, and a mother CPU memory 3 is a C memory.
The memory for storing the M data, the sending buffer CPU 4 is a CPU for controlling the recording and reproduction in the sending buffer 8, and the sending buffer CPU memory 5 is an OA (On Ai) to be described later.
r) The memory where data is stored, and the CM material storage unit 6 is C
The location where the M material is stored, the mother file 7 is a magneto-optical disk in which the CM material read from the CM material storage unit 6 is stored, and the sending buffer 8 is where the CM material read from the mother file 7 is stored. A magneto-optical disk.

That is, in response to an instruction from the operation terminal operation 1, the mother CPU 2 reads out the necessary CM material for each program from the CM material storage unit 6, writes the CM data into the memory 3, and stores the video / audio data of the CM material into the mother. Write to file 7.

On the other hand, when a copy command to the transmission buffer 8 is issued from the operation terminal operation 1, the mother CPU 2 reads out video / audio data of a predetermined CM material from the mother file 7, and the transmission buffer CPU 4 reads the video / audio data. Video /
The audio data is written to the transmission buffer 8.

First, CM data (hereinafter referred to as OA data) read from the CM material storage section 6 is, for example, 3
Are classified into different types of programs. First, regular OA data (hereinafter, also referred to as CMA) transmitted when there is no special program correspondence, second, multi-OA data (hereinafter, also referred to as M101) transmitted with special program correspondence, The third is multi-OA data (hereinafter also referred to as M599) which is also transmitted in correspondence with a special program.

As described above, a plurality of Cs are usually assigned to one program.
An M program is prepared, and any one of the CM programs is transmitted as occasion demands.

Such a file is created by the mother CPU 2 according to an instruction from the operation terminal 1. The created OA data is written in the memory 3, and the CM video / audio data corresponding to the OA data is written in the mother file 7.

FIGS. 2 to 5 show examples of the OA data file. 2 is OA data of the day (CMA), FIG. 3 is OA data of the day (M101), and FIG. 4 is OA of the day.
Data (M599), FIG. 5 shows OA data (CM
A) is shown.

The contents of these files will be described with reference to FIG. The frame / CM key 11 indicates a broadcast time. In this example, the time elapses in ascending numerical order. The frame code 12 indicates the type of OA data. In addition, CM materials are collected into several bundles, and this is called a frame.

DT13 is the length (time;
Seconds). Material code 14 is the classification name of CM material, CM
Address 15 is the CM address, OA address 16 is O
A address, CP17 is a flag indicating that copying has been completed, O
A is a flag indicating on-air completion.

The column in which only the frame / CM key 11, the frame code 12, and the DT13 are described is not a column for displaying a CM material, but a total time of a CM material (CM material in the frame) following the CM material. This is displayed by DT13.

Of these, those displaying the CM material are denoted by reference numerals (A) to (E) (FIGS. 2 to 5).

Referring to the OA 18 in FIG. 2, a flag of "#" is attached to the second line from the top. This indicates that OA has been completed up to this line (on-air has been completed). Further, the CP 17 has a flag of "#" over all lines. This indicates that the CM material has already been written in the transmission buffer 8. In other words, it indicates that these CM materials were used during the broadcast on the previous day.

These OA data (CMA, M101,
M599) is written into the memory 3, and the video / audio data of the CM material corresponding to the OA data is written into the mother file 7.

Next, the transmission buffering operation will be described with reference to the flowchart of FIG. FIG. 6 is a flowchart showing the transmission buffering operation.

First, a 0A sequential file is created (S
1). This OA order file is stored in the memory 3 by the mother CPU 2.
Create based on the content of

The 0A sequential file corresponds to the O in FIG. 2 to FIG.
The A data is rearranged in time order (order of frame / CM key 11). This is CM without OA flag 18
The materials are to be sorted.

FIG. 7 is a diagram showing a 0A sequential file of the day. This means that the OA data shown in FIGS.
It is rearranged in A order. Referring to FIG.
For materials (nu), (ru) and (o), CP17
The flag of “is not added. This indicates that the CM material is newly added to the OA sequential file.

The number of events (number of CM materials) of the OA sequential file is variable and is created until the maximum time that can be copied to the transmission buffer 8 (depending on the recording capacity of the transmission buffer 8) is reached. In addition, since some CMs are used repeatedly in the OA sequential file, duplicate CMs are created for the maximum time without being calculated.

This 0A sequential file is also created by the mother CPU 2, and the result is written into the memory 3.

Next, returning to FIG. 6, the OA address of the OA-completed CM is released (S2). FIG. 8 is a diagram showing data for managing the CM material in the transmission buffer on the previous day. The data for managing the CM material in the transmission buffer 8 is stored in BUF-A.
Display as DF. This is to display the CM material already written in the transmission buffer 8, and the mother CP
It is created by U2 and its data is written to memory 3.

The BUF / ADF file shown in FIG.
Referring to the A-order file (comparing both material codes 14), the CM materials CM0012 (nu) and CM shown in FIG.
2663 (e) is already recorded in the BUF / ADF file of FIG. So this CM
Since it is not necessary to record the materials CM0012 (nu) and CM2663 (e) in the transmission buffer 8, the CM materials CM0012 (nu) and CM2663 of this OA sequential file are not required.
A flag “#” is attached to the CP 17 in the column (e). FIG.
FIG. 8 is a diagram showing an OA sequential file to which a copied flag is added.

A flag of "#" is also attached to the CM material CM0012 (nu) of the OA data (CMA) (see FIG. 5) and the CP17 of the CM2663 (e). FIG. 10 is a diagram showing OA data to which a copied flag is added.

Referring to the BUF / ADF file of FIG. 8, the CM material CM0 existing in the OA order file of FIG.
It can be seen that 100, 1020, and 4141 are also recorded. Therefore, it is not necessary to record these CM materials in the transmission buffer 8, while the CM material CM2 of the BUF / ADF file shown in FIG.
995 (W) does not exist in the OA sequential file of FIG.
This is a CM that does not need to be transmitted to the transmission buffer 8 this time.
It means that it is a material. So, this CM material CM
2995 (W) is deleted from the BUF / ADF file of FIG. This is the release of the OA address of the OA-completed CM 1
9

First, C in the BUF / ADF file shown in FIG.
A flag "F" is added to the release 19 of the M material CM2995 (W). This “F” means that the CM material has been deleted from the BUF / ADF file. FIG.
FIG. 8 is a diagram showing a BUF / ADF file with a release flag.

Next, the CM material CM2995 (W) is BU
Delete (release) from the F.ADF file. FIG. 12 shows C
FIG. 11 is a diagram showing a BUF / ADF file from which M materials have been released. As a result, the OA address for 30 seconds is released from the OA address 3010 used in the CM material CM2995 (W).

Next, returning to FIG. 6, an OA address is assigned to the CM data of the buffer not yet transmitted in the OA sequential file (S3).

In the OA sequential file, an OA address is assigned to a CM material that has not been sent and buffered. Although the OA order file includes a CM material used repeatedly (see the material code 14 column in FIG. 9), the same OA address 16 is used for the same CM material.
Is configured to be assigned.

The allocation is performed in order from the head of the OA order file to CM materials without OA addresses.

If the length of the CM material is 15 seconds or less, the BU
An empty area is searched from the start address of each F / ADF file. If the length of the CM material exceeds 15 seconds,
An empty area is searched from the last address of each BUF / ADF file.

Referring to the OA sequential file in FIG.
It can be seen that the OA address has not yet been assigned to the material CM3131 (R). So, this CM material CM31
An OA address is assigned to 31 (R).

Since the CM material CM3131 (L) is a CM material of 15 seconds or less (refer to DT13 in the same figure), BUF.
The allocation location is searched from the start address of each ADF file.

As a result of the search, as shown in FIG.
OA for 30 seconds from OA address 3010 in DF file
Since the address has been released, its OA address 30
10 is assigned to the CM material CM3131 (R). FIG.
FIG. 3 shows an OA sequential file after OA address allocation.

Next, returning to FIG. 6, BUF / ADF data is created (S4). In other words, the CM material CM3131 is assigned to the OA address 3010 of the BUF / ADF file. The code after the assignment is (f). FIG.
FIG. 3 is a diagram showing a BUF / ADF file after OA address assignment.

Next, returning to FIG. 6, sending buffering is performed (S5). The sending buffering is performed for data in the OA sequential file to which an OA address is assigned and which has not been copied (CP17).

Now, there is an untransmitted buffering to which an OA address is assigned (CM material CM31).
31 (f), so that sending buffering is performed (S
6).

FIG. 15 is a signal flow chart showing transmission buffering control. The transmission buffering control will be described with reference to FIG.

First, the mother CPU 2 transmits untransmitted buffering data (non-copy data), that is, CM material CM31.
The OA data of 31 (f) is transferred to the sending buffer CPU4. The transfer is performed in units of 1CM material. The transferred data is stored in a memory 5 provided in the sending buffer CPU4.
Is stored in

Next, the mother CPU 2
To play (standby).

Next, the mother file 7 performs a disk read queue (preparation for reading) from the CM address (3131) of the untransmitted buffering data.

Almost simultaneously with this cue-up, the sending buffer CPU 4 queues up the disk of the sending buffer 8 from the OA address (3010) of the unsent buffered data and waits for writing (record standby).

Next, the sending buffer CPU 4 is
It notifies U2 that it has entered the write standby state (record standby).

Thereafter, when a start command is input from the operation terminal 1 to the mother CPU 2, the mother CPU 2 outputs a start (start) request to the transmission buffer CPU 4, and the mother CPU 2 starts reading to the mother file 7 (play). A start command is sent, and the sending buffer CPU 4 starts writing to the sending buffer 8 (record
Start) command.

In accordance with these instructions, the mother file 7 reads the video and audio of the CM material CM3131 (f), and the transmission buffer 8 writes the video and audio.

Next, returning to FIG. 6, the CM material CM3131
When the writing of (f) is completed, a copy (CP) completed flag "#" is added to the CM material CM3131 (f) in the OA sequential file and the OA data (S7). still,
Illustration is omitted.

The copy (CP) completed flag “#” is
Indicates that the data has already been written to the sending buffer 8. In addition, the flag includes a flag “$” indicating that the data has not yet been written to the transmission buffer 8, and a flag “B” indicating that the data has not yet been written to the mother file 7.

The copied flag of the frame data is added according to the flag state of the CM data in the frame. That is, when all the CM data in the frame are “△” and when the CM data in the frame is 1
There are two or more “△” data, and the other data is “#”
If “is”, “△” means that all CM data in the frame is “
In the case of # ","#"indicates that at least one
When "is", "E" is added respectively.

Also, CM material CM of BUF / ADF data
A flag “#” is also added to the copy (CP) column of 3131 (f) (not shown).

Then, a copy completion flag is added (S7).
Is completed, the process returns to S5. In S5, it is checked whether or not there is any untransmitted buffering to which an OA address is assigned. In this embodiment, the corresponding CM
Since there is only the material CM3131 (f), the transmission buffering is completed. If there is another applicable CM material, S6 and S7 are performed in the same manner as described above, and the process returns to S5.

FIG. 16 is a timing chart showing the operation of transmission buffering. Cue-up instruction (PLAY ST) from mother CPU 2 and sending buffer CPU 4
(BY and REC STBY) pulse signals are output (E and F in the same figure), and the mother file 7 receiving this signal is output.
And the sending buffer 8 performs cue-up (FIG.
D).

Next, the mother CPU 2 and the sending buffer C
When a pulse signal of a start command (start) is output from the PU 4 (FIGS. E and F), the mother file 7 receiving this signal starts reading (playing) with a slight delay from the pulse signal. Almost at the same time, the sending buffer 8 starts writing (recording) (FIGS. C and D).

The mother file 7 starts reading the corresponding CM material after a certain period of time (12 frames in the present embodiment) after the time (DT) allocated to the CM material.
(See FIG. A), and the transmission buffer 8 writes the CM material only for the time DT (see FIG. B).

Then, after 12 frames, the mother file 7 and the sending buffer 8 terminate (stop) reading and writing (see FIGS. 7A to 7D). On the other hand, the output of the CM material from the transmission buffer 8
Receives the OA order file from the mother CPU 2 and outputs the CM material to the outside from the transmission buffer 8 in the order of the broadcast time. At this time, since only one identical CM material is stored in the transmission buffer 8, the same material is repeatedly output from the output buffer 8 to the outside each time.

[0066]

According to the present invention, the first storage means for storing the program material, the reordering means for reading out the program material from the first storage means and reordering them in the order of the broadcast time, and the second storage means And storage control means for storing only one of the same program materials among the program materials rearranged by the rearrangement means and storing each of the different program materials in the second storage means. The second storage means stores only the minimum necessary program material.

According to still another aspect of the present invention, there is provided a read control means for repeatedly reading the same program material from the second storage means and transmitting the same to the outside in the order of broadcast time. All the program materials can be transmitted to the outside in the order of broadcast time based on the minimum program materials stored in.

As described above, since only the minimum necessary program material is stored in the second storage means, it is possible to effectively use the recording medium, and one edit is required for writing to and reading from the second storage means. This facilitates recording / reproducing work and replacement of program material. Also, if a recording medium that can be accessed randomly is used as the second storage means, the work of replacing the program material can be further facilitated.
