Movie "file creation starts.

The video production plan call screen 40 shown in FIG.
When the start button 43 is selected, the CPU 35
A broadcast playlist is created from the program table. Also,
When the rehearsal button 46 is selected, the CPU 35
A rehearsal playlist is created from the program table.
Similarly, when the “OK” button is selected on the rehearsal Movie setting screen shown in FIG. 4, a playlist for creating a rehearsal Movie is created.

FIGS. 5A and 5B show the structure of a playlist created from the program table 42. FIG. 5A shows a playlist for broadcasting, FIG.
The “Rehearsal Movie” file creation playlist set to “0” is shown.

In the playlist, first, the list type is
Then, the broadcast time, material machine, etc. are described. When the start button 43 is selected, the list type is “normal”
"NOR" indicating "TYPE = NOR" is described. When the rehearsal button 46 is selected, “REH” representing “rehearsal” is described as a list type, and “TYPE = REH”. Similarly, when the rehearsal Movie creation button 47 is selected and the actual device is used, “TYPE = REH-M-WITH-DEV”, and when the actual device is not used, “TYPE = REH-M-WITHOUT-DEV” DEV ".

That is, when this rehearsal moving image generation system is used in the first usage, the list type is “RE
HM-WITHOUT-DEV ", and when used in the second usage, the list type is" REH-M-WITH-DEV ".

When the time ratio setting is enabled in the creation of the “Rehearsal Movie” file, the time ratio is described following the list type. For example, when the time ratio is set to 1:10, if the actual device is used, “TYPE = REH-M-WITH-DEV, T-
RATE = 10 ``, TYPE = REH-M-WITHOUT-D if not used
EV, T-RATE = 10 ".

The created playlist is once analyzed by the CPU 35 of the moving image generation controller 30. And, if the list type described in the playlist is "NOR",
If it is "REH" or "REH-M-WITH-DEV", the CPU 35 notifies the CPU 21 of the broadcast equipment control device 20 of the playlist via the I / F 39 and the I / F 26.

When notified of the play list, the CPU 21 analyzes the play list. And the list type is "NOR"
If so, all the connected broadcasting equipment is controlled so as to output the specified video at the specified time.
If the list type is “REH”, the rehearsal starts immediately regardless of the designated time. This rehearsal is exactly the same as the main broadcast, except for the time and the equipment used and the length of time.

Next, if the list type is "REH-M-WITHOUT-DE
The processing of the CPU 35 in the case of "V" will be described. FIG. 6 is a diagram showing an example of an image used when a “rehearsal Movie” file is created without using an actual device. (A) indicates a VTR, (B) indicates an SS-still image, (C) indicates a CG-character, and (D) indicates a camera image.

The HD 33 stores an image image as shown in FIG. 6 in advance. When the playlist is analyzed and the list type "REH-M-WITHOUT-DEV" is recognized, the CP
U35 creates a "Rehearsal Movie" file using these image images.

FIG. 7 shows “Rehearsal Movie” without using the actual machine.
4 is a flowchart showing an operation procedure of the image generation control unit 34 when a file is created. When the rehearsal moving image generation system is used in the first usage, the CPU 35 of the image generation control unit 34 first positions the processing index at the head of the playlist (step S1).
A new "Rehearsal Movie" file is opened (step S2). The DUR is fetched for the event at which the processing index is located (step S3),
The number of frames (the number of frames) of the event is calculated (step S4). Then, image images corresponding to the material machine of the event being processed are added to the moving image file by the number of frames calculated in step S4 (step S5). The processing index is advanced to the next event (step S6), and if the final event has been processed (step S7), the creation of the “Rehearsal Movie” file ends (step S6).
8). The created file is a SCSI standard I / F 37
Is stored in the HD 33. If the final event has not been processed, the process returns to step S3.

As described above, with the rehearsal moving image generation system of the present invention, it is possible to confirm the entire configuration of a video to be produced without using any actual broadcasting equipment.
Movie "file.

Next, when the list type of the notified playlist is “REH-M-WITH-DEV”, the CPU 21
Describes the procedure for creating a “Rehearsal Movie” file using an actual device. This is a second usage of the rehearsal video generation system of the present embodiment.

FIG. 8 shows “Rehearsal Movie” in actual use.
6 is an overall flowchart when a file is created. When the list type of the analyzed playlist is “REH-M-WITH-DEV”, the CPU 35 of the image generation control unit 34 transmits the broadcast equipment control device 2 via the I / Fs 39 and 26.
The CPU 21 is notified of the playlist (step S11). Next, the CPU 35 newly opens the “Rehearsal Movie” file and waits for a moving image to be input via the capture board 36 (step S12).

The CPU 21 of the broadcast equipment control device 20
A DUR table is created from the notified playlist (step S13). That is, for each event described in the playlist, the number of rehearsal frames (RF)
= Time ratio × Event DUR × 30 is calculated using the work memory 28 or the like. Then, the processing index is positioned at the head of the playlist (step S1).
4).

Here, the switcher 12 is constantly input with the respective image images from the image generating devices 13 to 16. The CPU 21 creates the D created in step S13.
With reference to the UR table, the data of the image generating apparatus of the event in which the processing index is located and the number of rehearsal frames are acquired. Then, the CPU 21 sets a control command based on the obtained data (step 15) and notifies the switcher 12 (step S1).
6).

Thereafter, the CPU 21 keeps reducing the number of rehearsal frames by one in synchronization with the time signal (step S17). When the number of rehearsal frames becomes 0 (step S18), the processing index is advanced to the next event (step S19). Here, if the final event has been processed (step S20), the CPU 21
35 is notified of the end of the moving image generation (step S21). C
PU 35 closes the file opened in step S12,
The generation of the rehearsal moving image file ends (step S22). If the last event has not been processed, the process proceeds to step S15 again.

Here, step S16 of the flowchart is described.
A control command that the CPU 21 notifies the switcher 12 will be described. FIG. 9 is a diagram showing a format of a control command that the CPU 21 of the broadcast equipment control device 20 shown in FIG. 2 notifies the switcher 12 via the I / F 22.

The control commands include a command 61 for notifying setting information and a command 62 for notifying additional information, and these two commands 61 and 62 have the same configuration. That is, STX (0x in the start of text)
02) and BC (byte count, the next CMD ~
The number of bytes up to the last CS), CMD (indicating the type of command), information corresponding to the command, and CS (checksum, the lower 1 byte of the sum of the bytes BC to CS is 0) Value).

Here, STX, BC, CMD, C
S is 1 byte each. The two-digit number after 0x indicates that the number is in hexadecimal notation, for example, 0x0A indicates the decimal number 10.

The command 61 is used to change the cross point of the switcher 12, that is, to make a setting for switching the input signal.
e ”, ..., 0x80,“ Transition Start (Pre
set BUS-> Program BUS) ", 0x81 means" Program
BUS Set ", 0x82 means" Preset BUS Set ", 0x
83 is "Effect BUS Set", 0x84 is "Tran
sition Speed Set ”.

In the present embodiment, the image switching by the switcher 12 is considered on the premise of cut-in / cut-out. However, by changing the transition time, image switching with effects such as mixing can be performed. In that case, set the crosspoint for the next event to “Preset BUS
Set ”and then switch with“ Transition Start ”.

As described above, with the rehearsal moving image generating apparatus of the present invention, it is possible to generate a “rehearsal Movie” file compressed at an arbitrary time using actual broadcasting equipment.

Next, the case where the rehearsal Movie playback button 48 is selected on the video production plan call screen 40 shown in FIG. 3 will be described. FIG. 10 is a diagram showing a state of a rehearsal moving image display screen for reproducing the created “rehearsal Movie” file.
