Description

  The present invention relates to a technique for displaying subtitles in accordance with video display, and more particularly to a technique for realizing appropriate subtitle display in accordance with a change in a broadcast frame of a program.

  Currently, terrestrial digital broadcasting has a function of displaying subtitles at designated positions on the screen in accordance with the video display of a program in order to enhance visual effects and consider viewing by visually impaired persons.

By the way, in a broadcast program transmission system that broadcasts a program with subtitles, the transmission material of the program with subtitles is recorded in a server in advance, and the corresponding material is reproduced according to an instruction from an automatic program transmission control device (APC). , Is supposed to do on-air. In such on-air processing, when there is a change in the broadcast frame before on-air, the video is extracted or replaced in the material stored in the server in accordance with the change, and the subtitle text associated therewith is changed. Extraction and replacement are performed (for example, Patent Document 1).
JP2007-202094A.

  However, since most of the operations for extracting and replacing subtitle sentences by changing the broadcast frame are performed manually by the operator, the operator is forced to perform complicated operations.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a caption sending apparatus and its caption editing processing method capable of automatically re-editing caption material to be inserted into a broadcast program in accordance with broadcast frame change or rebroadcast.

  In order to achieve the above object, a caption transmission device according to the present invention is inserted into an on-air broadcast program in advance in a caption transmission device used in a broadcast system that provides a broadcast program that displays a caption at a designated position on a screen. A storage unit for storing subtitle material data having a page structure; an insertion unit for inserting subtitle material data reproduced from the storage unit into a broadcast program; and a control unit for controlling reproduction of the storage unit. , On-air program information that defines broadcast start timing and broadcast time frame according to the edit instruction input, recording area start position and end position, and recording time information included in the program management information, at least after the start position and end position Subtitle material data is sequentially played back from the storage unit for each roll by specifying the previous fixed period as a roll, and the played roll is inserted into the broadcast program. Having that subtitle editing function.

  According to this configuration, the original subtitle material data is only registered once in the storage unit, and the subtitle material data stored in the storage unit is divided into a plurality of rolls automatically or according to an operator's editing instruction input. Then, it is sequentially reproduced for each roll and inserted into the broadcast program.

  Therefore, the subtitle material to be inserted into the broadcast program can be automatically reedited in accordance with the change of the broadcast frame or rebroadcast.

  The storage unit stores a plurality of subtitle material data to which subtitle IDs for identifying broadcast programs to be inserted are added, and the control unit receives subtitle material data from the storage unit for subtitle material data corresponding to the designated subtitle ID. Each roll is played back sequentially, and the played roll is inserted into the broadcast program.

  According to this configuration, for example, even when a plurality of broadcast programs are mixed and aired in a certain time frame, subtitles corresponding to the broadcast programs can be specified only by specifying the subtitle ID corresponding to the broadcast program to be on air. Material data can be inserted.

  A designation means for designating the roll or the reproduction time is provided, and the control unit changes the roll or the reproduction time according to the designation input of the roll or the reproduction time.

  According to this configuration, an operator can arbitrarily select and play a roll or a playback time, thereby playing back only the role that the operator determines to be necessary and inserting it into a broadcast program, or changing the playback time of the roll. can do.

  As described above in detail, according to the present invention, there is provided a subtitle transmission apparatus and subtitle editing processing method capable of automatically reediting subtitle material to be inserted into a broadcast program in accordance with a change in broadcast frame or rebroadcast. be able to.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing the configuration of a broadcast program transmission system to which a caption transmission device according to the present invention is applied. In FIG. 1, a program server 11 stores program material data of an on-air broadcast program in advance, and selectively reproduces the corresponding program material data in accordance with an on-air instruction signal given from the APC 12. This reproduction data is output on the air via the insertion unit 13.

  On the other hand, as shown in FIG. 2, the storage unit 14 stores subtitle material data to which a subtitle ID (for example, 1234561J) corresponding to program material data is assigned, and according to an on-air instruction signal given from the APC 12 The corresponding caption material data is read by the caption editing device 15 and sent to the insertion unit 13. The insertion unit 13 inserts the caption material data into the program material data and outputs it on the air.

  The caption editing device 15 performs the writing / reading control of the caption material data in the storage unit 14 in accordance with the operation input instruction of the operation terminal 16, and the caption editing device 15 particularly has the caption editing function according to the present invention. Is installed.

In the above configuration, processing of the caption editing function will be described below.
FIG. 3 is a flowchart showing a processing procedure of the caption editing device 15. First, an edit instruction input from the operation terminal 16 is determined (step ST3a), and if there is an instruction input, program information from the present time to before the start of on-air is acquired from the host controller (EDPS) 17 (step ST3a). ST3b).

  Subsequently, management information for each of the acquired program information is acquired from the EDPS 17 (step ST3c), the IN / OUT points of the roll recording area and the recording time are obtained from the management information (step ST3d), and the playback location in the storage unit 14 Is specified (step ST3e).

Next, a roll is designated in the storage unit 14, and a reproduction portion corresponding to the designated roll , that is, subtitle material data is read (step ST3f). Here, the caption editing device 15 determines whether or not the roll overlaps the transmission timing (step ST3g), and if it overlaps (Yes), deletes the overlapping part of the caption page (step ST3h).

  The above caption editing process is repeatedly executed for all the captions up to the recording time, and when the execution of all captions is completed, the editing process is terminated (step ST3i).

  FIG. 4 shows an example in which caption material is inserted into a broadcast program. As shown in FIG. 4, program material data is stored in the program server 11, and a CM (commercial message) is inserted between the time code (TC) “10:00” and “10:15” of the program. Is output on air. At this time, the caption editing device 15 corrects the TC “10:15” of the caption material data stored in the storage unit 14 to “11:15” in accordance with the program information and management information acquired from the EDPS 17, and the TC “28” : 30 "is corrected to" 29:30 ".

  By the way, when only the TC start timing is different without changing the roll time frame (DT value), only the transmission timing of each subtitle page is updated. A rule for generating a pattern in which a change in the time frame of the roll occurs is as follows.

FIG. 5 shows an example of deleting the caption page of the head cut portion.
That is, when the transmission timing is in the head cut portion, the caption editing device 15 deletes the caption page in the head cut portion. If there is a caption page with a transmission timing of 10:05, it is not deleted.

FIG. 6 shows an example of deleting the subtitle page of the rear cut portion.
That is, when the transmission timing is in the rear cut portion from 2 seconds before, the caption editing device 15 deletes the caption page in the rear cut portion from 2 seconds ago. Then, a subtitle erasure packet page is inserted one second before the next cut.

FIG. 7 shows an example of deleting the subtitle page of the divided part.
That is, when the transmission timing is in the divided portion from 2 seconds before, the caption editing device 15 deletes the caption page in the divided portion from 2 seconds ago. Then, a caption erasure packet page is inserted one second before the division.

FIG. 8 shows an example of cutting a CM portion.
That is, when the transmission timing is in a CM sandwiched between rolls, the caption editing device 15 cuts the CM portion. Even if the CM portion between the rolls is cut, the front and rear rolls remain as independent frames. In this case, the roll is continuous. If there are overlapping frame times between the previous and next rolls, a subtitle format error is assumed.

FIG. 9 shows an example of post-extension.
That is, when the roll frame time is extended later, the caption editing device 15 does not perform any special processing. However, if there is an overlap in the frame time of the next roll, a subtitle format error is assumed. Since there is no subtitle page to be transmitted in the extended time zone, the maximum extended time is set to 30 minutes as an operation restriction.

FIG. 10 shows an example of pre-extension.
That is, when the roll frame time is extended before, the caption editing device 15 does not perform any special processing. However, if there is an overlap in the frame time of the previous roll, a subtitle format error is assumed. The maximum length of the previous extension is the frame time of the previous CM or the maximum interval without caption page is 30 minutes. If it is more than that, an overlap occurs in the time frame of the previous roll, so a subtitle broadcast format error is assumed.

  As described above, in the above embodiment, original subtitle material data is stored in the subtitle editing device 15 automatically or in accordance with an operator's editing instruction input from the operation terminal 16 only by registering the original subtitle material data once in the storage unit 14. The subtitle material data stored in the unit 14 is divided into a plurality of rolls, the subtitle material data is sequentially reproduced for each roll, and the insertion unit 13 inserts the subtitle material data for each roll into the broadcast program.

  Therefore, the subtitle material to be inserted into the broadcast program can be automatically reedited in accordance with the change of the broadcast frame or rebroadcast.

  In the above embodiment, the storage unit 14 may store a plurality of caption material data to which a caption ID for identifying a broadcast program is added. Then, the caption editing device 15 causes the subtitle material data corresponding to the designated subtitle ID to be sequentially reproduced from the storage unit 14 for each roll, and the inserted unit 13 inserts the reproduced role into the broadcast program. . In this way, for example, even when a plurality of broadcast programs are mixed and aired in a certain time frame, only by specifying the subtitle ID corresponding to the broadcast program to be on air, the caption material suitable for the broadcast program Data can be inserted.

  Furthermore, in the above embodiment, the caption editing device 15 may change the roll or the reproduction time in accordance with the designation input of the roll or the reproduction time from the operation terminal 16. In this way, the operator can arbitrarily select and play a roll or playback time, thereby playing back only the role that the operator has determined to be necessary and inserting it into a broadcast program, or changing the playback time of the roll. can do.

  Further, in the above embodiment, since the program material data and the caption material data are created separately, it is not necessary to modify the video together when it is necessary to modify and modify the caption.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
