Description

  The present invention is a system for recording moving images such as CMs, programs, VAF (Video Audio Filing) and still image material on a video server, and superimposing digital subtitle data on material data not containing digital subtitle data or superimposing in advance. This is related to editing of digital subtitle data.

FIG. 3 is a conventional material registration system diagram in the program bank system. A conventional bank system for recording moving images and still image materials such as commercials, programs, and VAFs on a video server does not include a subtitle superimposition system in the bank system, and video data of material with digital subtitle data superimposed is video. It had to be recorded on the server. That is, under the control of the bank registration controller 4, the material data on which the digital subtitle data is superimposed from the VTR 1 or the like can only be recorded on the video server 3 via the matrix switcher 2.

Therefore, in the conventional program bank system, it is not possible to superimpose digital subtitle data on material data that does not contain digital subtitle data, or to edit digital subtitle data that is pre-superimposed, and urgently replace the digital subtitle data. When necessary, we could not respond.
For example, when previewing material filing a foreign movie or animation, etc., if there are inappropriate expressions such as prohibited broadcast terms or prohibited terms based on the traffic rules of each broadcasting station in the already superimposed digital subtitles,
1) Send the master tape back to the creator of the caption data, 2) Remake the tape at the creator, 3) Send the master tape to the broadcast station again, 4) Re-filing at the broadcast station registration table, 5) Recorded material A procedure such as performing the preview work of the user occurs.
Therefore, for materials that do not have time until the broadcast date, it is necessary to change the broadcast schedule and replace it with another material, which will also require replacement of the numbered material (CM) at the same time. For this reason, the amount of work increases.
In many cases, the subtitle superimposing system alone requires a time code from the VTR, which is usually obtained from the remote connector of the VTR. Here, the program bank system also uses a remote connector to perform VTR control, so the use of the remote connector has become a form for both parties and has not been realized.
The present invention eliminates these disadvantages, and a program bank that can easily add and edit digital subtitle data to material data that does not contain digital subtitle data or material data that already has digital subtitle data superimposed on it. The purpose is to realize the system.

  To achieve the above object, the present invention introduces a digital subtitle inserter into a re-entry system of a matrix switcher in the bank system in a bank system that edits and transmits at least moving image material, and the digital subtitle inserter At least one of superimposition of digital subtitle data from the digital subtitle superimposing device and editing of digital subtitle data in the material data superimposed with digital subtitle data on material data not including subtitle data input via the reentry system of the switcher Is performed based on the caption superimposition timing synchronized with the internal clock of the registration controller in the bank system, and the material data on which the digital caption data is superimposed is recorded in the video server via the matrix switcher. It is a link system.

According to the present invention, it is possible to superimpose digital subtitles from a plurality of VTRs by introducing a subtitle inserter into the reentry system.
In addition, by using the internal clock of the registered controller, it is possible to realize a subtitle superposition method that does not require a time code from the VTR. Data can be edited.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a block diagram showing a material registration system configuration to which a caption superimposing function is added in the program bank system of the present invention.
1. First, the subtitle inserter 6 introduced in the reentry system of the matrix switcher 2 superimposes the subtitle data 7 via the registration controller 4 on the material data without subtitles from the VTR 1 and returns the signal to the matrix switcher 2 again. The configuration and operation for registering to 3 will be described.
1) A digital subtitle inserter 6 is added to the reentry route of the matrix switcher 2 in the bank system shown in FIG.
2) From the registration / preview terminal 5, select the VTR 1 in which the material data on which the digital subtitle is to be superimposed is recorded.
(3) From the registration / preview terminal 5 through the registration controller 4, playback of the VTR 1, matrix switcher 2, video server 3, etc. are controlled to connect the video / audio system.
4) Using the subtitle data addition edit screen (not shown) of the registration / preview terminal 5, the subtitle data 7 to be superimposed in the NAB and ARIB formats is read by the registration / preview terminal 5, and the digital subtitle inserter is read via the registration controller 4. 6
5) Next, the ON / OFF position of the input caption data is determined by cueing the material data.
6) The above 4) and 5) are repeated, and the caption content to be superimposed and the ON / OFF positions of the caption data are determined.
7) Thereafter, the subtitle data 7 is transferred from the registration controller 4 to the subtitle inserter 6 via the serial interface to generate subtitle auxiliary data.
8) When recording on the video server 3 is started, the material data of the SDI signal reproduced from the VTR 1 is input to the digital subtitle inserter 6 through the matrix switcher 2 and the subtitle data input via the registration controller 4 7 is superimposed.
9) The material data on which the digital subtitle is superimposed by the digital subtitle inserter 6 is input again to the decoder of the video server 3 through the matrix switcher 2, and filing is performed as the material data with subtitle.
10) Then, the registration / preview terminal 5 confirms whether the digital subtitle data is normally superimposed.

2. Next, the subtitle inserter 6 introduced in the reentry system of the matrix switcher 2 superimposes the subtitle-free material data recorded in the video server 3 and the subtitle data 7 via the registration controller 4 or has already been superposed. A configuration and operation for adding and editing data, returning the signal to the matrix switcher 2 and re-registering with the video server 3 will be described.
1) A digital subtitle inserter 6 is added to the reentry route of the matrix switcher 2 in the bank system shown in FIG.
2) From the registration / preview terminal 5, select the VTR 1 on which digital subtitles are superimposed and material data to be additionally edited is recorded.
(3) From the registration / preview terminal 5 through the registration controller 4, playback of the VTR 1, matrix switcher 2, video server 3, etc. are controlled to connect the video / audio system.
4) Using the subtitle data addition editing screen (not shown) of the registration / preview terminal 5, the NAB and ARIB formats are superimposed, and the subtitle data 7 to be additionally edited is read by the registration / preview terminal 5, via the registration controller 4. Input to the digital subtitle inserter 6.
5) Next, the ON and OFF positions of the input subtitle data are determined by cueing the material data recorded in the video server 3.
6) The above 4) and 5) are repeated, and the added or edited subtitle contents and the ON / OFF positions of the subtitle data are determined.
7) When only a part of subtitle data is edited, the material data in the video server 3 is cued at the head position of the main event data containing the subtitle data. When new caption data is superimposed on material data without caption data, cueing is performed at the head position of the material data in the video server 3.
8) Thereafter, the subtitle data 7 is transferred from the registration controller 4 to the subtitle inserter 6 via the serial interface to generate subtitle auxiliary data.
9) The material data reproduced from the video server 3 is input to the digital subtitle inserter 6 through the matrix switcher 2 and superimposed on the subtitle data 7 input via the registration controller 4.
10) The material data on which the digital subtitle is superimposed by the digital subtitle inserter 6 is input again to the decoder of the video server 3 through the matrix switcher 2, and filing is performed as material data with subtitles (other material data). .
11) Then, the registration / preview terminal 5 confirms whether the digital subtitle data is normally superimposed.

Here, a synchronization method between the time code of the caption data and the caption superimposition timing will be described with reference to the time chart of FIG.
1) The time difference between the time code for reproducing the VTR 1 in advance and the time code for starting the superimposition of subtitle data (for example, 4 seconds in the present embodiment), and the time difference between the time codes between subtitle data (for example, the present embodiment) 1 second in the example) is held inside the bank system (for example, the registration controller 4).
2) At the time of actual material recording, for example, after the VTR 1 is started at time (9: 59: 57: 00), the above difference (4 seconds) is counted by the internal clock of the registration controller 4 (10 : 00: 01: 00), superimposition of subtitle data a is started, and superimposition of subtitle data a is completed at a time one second later (10: 00: 02: 00).
3) Then, at the time (10: 00: 03: 00) after the above difference (1 second), superimposition of the caption data b is started, and at the time 1 second later (10: 00: 04: 00) The superimposition of data a is finished. Thereafter, the above processes 2) and 3) are repeated in accordance with the caption superimposition timing.
As described above, the registration controller 4 controls subtitle superposition to synchronize the material and the time code of the subtitle data.
