JP 2003-348525 A

As described above, in the prior art, the time code of the original material tape is not held in the editor 105 or 208, the recording VTR 108 or the editing tape 109, or the broadcast material recording unit 201. For this reason, the time code of the original material cannot be used after editing. Furthermore, even if the time code is set at the time of editing, the time code may be lost when writing in the broadcast material recording unit, and the time code set at the time of editing may not be used.
Further, the above-mentioned Patent Document 1 describes a program production / sending device that receives and edits program material via a network, that is, a program broadcasting station that broadcasts a program via the network. However, the description of the time code which is the subject of the present invention is not disclosed at all.
An object of the present invention is to provide a program editing and sending system in which a time code necessary for editing, such as a time code of an original material tape, is not lost.

  In order to achieve the above object, the program editing / sending system of the present invention saves the time code necessary for editing, such as the time code of the original material tape, in the database, so that the time code of the original material is edited. The time code set at the time of editing can be used at the time of broadcasting.

That is, the program editing / sending system of the present invention is a program editing / sending system for recording, editing, and broadcasting broadcast materials, and uses the time code information of the original material in the editor to improve the efficiency of editing work. It is.
Furthermore, the program editing / sending system of the present invention is a program editing / sending system for recording, editing, and broadcasting broadcast materials, storing time code information set at the time of editing in a database, and referring to the time code information in the database. By doing so, the sending material is sent out.

  According to the present invention, the time code of the original material and the time code set at the time of editing can be used in the program editing / sending system, so that the efficiency of editing work and the reliability of program sending can be improved.

  The present invention records an original material for use in broadcasting in a broadcast material recording unit that can be randomly accessed, edits the recorded original material by an editor connected via a network, and edits the edited broadcast material. This is a program editing and sending system that records in a broadcast material recording unit via a network and broadcasts according to a playlist. Also, when recording the original material or edited broadcast material in the broadcast material recording unit, the time code of the original material and the edited broadcast material is saved in the database, and saved in the database when editing and sending the broadcast material. It is possible to refer to the time code. As a result, it is possible to improve work efficiency and improve the reliability of sending program material.

Time information recorded on the tape on which video and audio information is recorded at the same time as the recording is referred to as a time code. The time code is represented in units of hour [h], minute [m], second [s], and frame [f].
In order to transmit original materials and edited broadcast materials via a network, they are transmitted as digital data and are often compressed and transmitted, and the importance of time codes is increasing. The time code is also required when matching video and audio.
The value of one frame of the time code is obtained by dividing 1 [s] into 30. For example, in the NTSC (National Television System Committee) system, the frame rate is 29.97 [fps], so that 0.03 [fps] at 1 [s], that is, 108 frames at 1 [h]. Since this will require a correction, the timecode of each source material and the timecode of the broadcast material after editing may be required when sending those materials. .

  Hereinafter, the related art will be described in detail with reference to the accompanying drawings. In each drawing, parts having common functions are denoted by the same reference numerals, and redundant description thereof may be omitted.

With reference to FIG. 3, an embodiment of the present invention in which the time code on the original material tape is used in the editor will be described. FIG. 3 is a block diagram of a part of the program editing / sending system according to the present invention, and shows a configuration of a part for editing program material. 101 is a video tape on which broadcast material is recorded (hereinafter referred to as an original material tape), 102 is a reproduction VTR (Video Tape Recorder), 104 is an original material video / audio signal, 201 is a broadcast material recording unit that is randomly accessible, 303 is a control unit, 203 is a reproduction control signal, 204 is an original material recording / reproduction control signal, 205 is original material data recorded in the broadcast material recording unit 201, 304 is an editor, and 206 is edited by the editor 304. 209 is a transmission terminal, 207 is a broadcast material transmitted from the broadcast material recording unit 201 via the transmission terminal 209 according to an instruction from the control unit 202, 301 is a database, and 302 is Reference time code data.
In FIG. 3, all the connecting lines other than the input line (input from the original material tape 101) to the reproduction VTR 102 and the output line (output to the broadcast material recording unit 201) are network lines.

In FIG. 3, the broadcast material is recorded on a video tape and brought in as an original material tape 101. When the reproduction control signal 203 is output from the control unit 303 to the reproduction VTR 102, the reproduction VTR 102 reproduces the original material tape 101 and outputs the reproduced video signal 104 to the broadcast material recording unit 201. . In addition, the reproduction VTR 102 outputs the time code data (reference time code data 302) of the reproduced video signal 104 to the control unit 303.
The broadcast material recording unit 201 records additional information such as a material name in association with the input video signal 104 together with the video signal 104.
The control unit 303 further outputs the input reference time code data 302 to the database 301 as reference time code data 302. The database 301 records the input reference time code data 302 in association with additional information such as a material name so as to correspond one-to-one with the video signal 104 of the original material recorded in the broadcast material recording unit 201. To do. That is, the reference time code data 302 is created and stored in the database 301 so as to correspond one-to-one with the material recorded in the broadcast material recording unit.
For example, if the material name recorded on the original material tape 101 is “material A” in the data area in the database 301, the reference time code data 302 is “material A, 01: 00: 00: 00”, material name. Is “Material B”, “Material B, 10: 00: 00: 00” is recorded, and if the material name is “Material C”, “Material C, 01:00:00” is recorded.

In the editor 304, when the operator starts editing work, the broadcast material recording unit 201 is requested for the original material 205 for editing via the network line, and the reference time corresponding to the requested original material 205 is 1: 1. Request code data 302 from the database.
The broadcast material recording unit 201 outputs the requested original material 205 to the editor 304 via the network line. The database 301 also outputs the requested reference time code data to the editor 304.
In the editor 304, during editing, when displaying the time code on a monitor (not shown) attached to the editor 304, the operator adds the reference time code to the time code of the current location, thereby adding the time code of the original material. The corresponding time code (time code at the time of recording the original material) can be used. In other words, the operator compares the time code (reference time code) at the time of editing displayed on the screen with the time code at the time of recording the original material, thereby determining the correspondence between the video displayed together and the time code. I can confirm.
Here, the time code of the current location is relative to the starting position of the currently displayed original material as a reference (0 [h], 0 [m], 0 [s], 0 [f]). Time code.
For example, the time code displayed on the screen (displayed in the order of [h], [m], [s], [f]) is that the time code of the reference point is (1) “10: 00: 00: 00” When the current time code is (2) “00: 02: 30: 0”, the added time code (3) “10: 02: 30: 0” is displayed. The time code display may be all (1) to (3), or only (3) or (1) and (3) are displayed, depending on the operator's selection.

  Next, the use of the time code at the time of broadcasting on the edited broadcast material (for example, edited video data 206) will be described with reference to FIGS. FIG. 4 is a block diagram illustrating only the database 301, the broadcast material recording unit 201, and the editor 304 in the block configuration diagram described in the embodiment of FIG. FIG. 5 is a block diagram illustrating only the database 301, the broadcast material recording unit 201, and the control unit 303 in the block configuration diagram described in the embodiment of FIG.

In FIG. 4, the edited broadcast material (for example, the edited video data 206) has a time code for writing to the VTR, but is transmitted via the network line 200 and recorded in the broadcast material recording unit 201. The broadcast code does not reflect the time code. Therefore, when the broadcast material 206 is output from the editor 304 to the broadcast material recording unit 201, the original time data corresponding to the broadcast material 206 corresponding to the database 301 in the one-to-one correspondence with the reference time code data at the time of broadcasting. 401 is written.
For example, if the material name of the broadcast material 206 is “material X”, the reference time code data 401 is “material X, 01: 00: 00: 00”, and the material name is “material Y”. "Material Y, 10: 00: 00: 00", and if the material name is "Material Z", "Material Z, 01: 00: 00: 00", etc. are recorded.

At the time of broadcasting, as shown in FIG. 5, the control unit 303 outputs a time code request signal 501 to the database 301 in order to request the reference time code data 401 of the broadcast material (for example, edited video data 206). The database 301 outputs the requested time code data 401 to the control unit 303.
At the time of broadcasting, in the control unit 303, the operator checks whether there is any abnormality in the transmitted video or audio by looking at a monitor for transmission monitoring (not shown) included in the master or the like connected to the transmission terminal 209. At this time, the control unit 303 confirms the time code by displaying the time code obtained by adding the elapsed time to the reference time code obtained from the database 301 on the monitor.

As in the above-described embodiment, conventionally, when recording a material from a tape in a broadcast material recording unit, the broadcast material recording unit does not have time code data, so the time code information of the original material is discarded. However, in the present invention, at this time, the broadcast material recording unit and the control unit that controls the VTR read the current time code on the VTR and record it in the database, so that the time code of the original material is stored in the database. Can leave.
Furthermore, in the present invention, when the editing material is acquired from the broadcast material recording unit via the network line, the editor simultaneously acquires the time code information of the corresponding material from the database and displays it as the reference time code. This makes it possible to use the time code of the original material VTR during editing work.
Further, when the editing is completed, the reference time code set on the editing machine is written in the database, so that the time code set on the editing machine at the time of broadcasting can be used.

  According to the above embodiment, in the program editing and sending system for recording, editing and broadcasting broadcast material, the broadcast material recording unit for recording the original material, the database, and the control for saving the time code data of the original material in the database. And an editor that acquires the original material recorded in the broadcast material recording unit via a network line, edits the acquired original material and edits the broadcast material, and stores the time code data recorded in the database. An editing system using a broadcast material storage device and a network in a program editing and transmission system including an editor for setting a time code using the data and recording the set time code data in a database and recording it in a broadcast material recording unit Can handle time codes in the same way as conventional tape editing machines, so that the efficiency of editing can be maintained. That.

  Further, according to the above embodiment, in the program editing / sending system for recording, editing and broadcasting the broadcast material, the broadcast material recording unit for recording the original material, the database, and the time code data of the original material are stored in the database.
