BACKGROUND OF THE INVENTION
The present invention relates to a video / audio material recording apparatus in a broadcasting station, and more particularly to a video / audio material recording apparatus in which a search for recorded video / audio material is facilitated.
[0002]
[Prior art]
In broadcasting stations, news such as news gathering is recorded using a video tape as a recording medium. In recent years, magneto-optical disks or hard disks have been used as the recording medium.
[0003]
FIG. 3 schematically shows an example of a news transmission system in such a broadcasting station. In the news gathering unit 100, a news gathering schedule such as news is created and supplied to the material recording device 101. This material recording device 101 has a function as a receiving port for collected video and audio material (hereinafter referred to as material), and is for recording the received material. In many cases, the coverage is performed according to the coverage schedule created in the coverage section 100, and the material obtained by the coverage is recorded and recorded on a recording medium such as a video tape in the material recording device 101.
[0004]
At this time, the material is supplied to the material recording apparatus 101 by various methods. For example, as shown in the figure, supply of material via a line 102a using a public line such as satellite communication or digital telephone line, supply from a video tape collected by a camera-integrated video tape recorder 102b, There is a supply in which video tapes provided by others are reproduced by the video tape recorder 102c.
[0005]
In this way, the material recorded in the material recording apparatus 101 can be searched by, for example, the terminal 105 connected to the material recording apparatus 101, and the searched material is sent to the outside such as the editing unit 106 described later. Is output. A part of the material of the material recording apparatus 101 is sent to and stored in the material storage unit 103. In the material storage unit 103, for example, a large number of material video tapes 104 on which materials are recorded are stored and managed.
[0006]
The editing unit 106 edits the material according to the program item table created by the program unit 107. For example, a necessary material is searched from the materials recorded in the material recording device 101 by the terminal 105 or the like, and the material obtained by the search is supplied to the editing unit 106. Then, editing is performed based on the material supplied in the editing unit 106, and the edited material is supplied to the transmission material storage device 108.
[0007]
In the transmission material storage device 108, the material scheduled to be transmitted edited by the editing unit 106 is stored. In the transmission material storage device 108, similarly to the material recording device 101 described above, it is possible to search for materials scheduled to be transmitted stored by the terminal 109. From the transmission material storage device 108, the material scheduled to be transmitted is transmitted to the outside for broadcasting by operating the terminal 109 or the like. The material broadcasted in this way may be combined into a plurality of materials for preservation. In this case, the material required for unification is retrieved by the terminal 109 and supplied to the tape unifying apparatus 110. The supplied plurality of materials are unified by the tape unifying apparatus 110 to be a single tape for storage 111.
[0008]
[Problems to be solved by the invention]
Conventionally, in such a system, the material is often recorded on the material recording device 101 as a video tape as a recording medium. In this case, various additional information such as the coverage and transfer time of the material recorded on the video tape is written down on paper and attached to the video tape.
[0009]
In the case of such a material management method, the user had to perform material distinction and search of recorded contents by using this memo for each video tape on which the material was recorded in this way. .
[0010]
In recent years, magneto-optical disks and hard disks have come to be used as recording media for this material. When these recording media are used, a plurality of materials are usually recorded on one recording medium. Even when the material is recorded on a video tape, a cart machine capable of storing a large number of video tapes may be used. In the case of this cart machine, the entire cart machine is regarded as one recording medium. As described above, when a plurality of materials are recorded on one recording medium, there is a problem that it is not possible to adopt a conventional method of attaching a memo to each recorded material.
[0011]
Further, for example, in the material recording apparatus 101 of FIG. 3 described above, a case where the communication line 102a has a plurality of lines can be considered. In this way, when materials are supplied simultaneously from a plurality of input lines and recording is performed in the material recording apparatus 101, the materials are supplied one after another from various directions. Cannot secure enough time to record the information. Therefore, there is a problem that it becomes difficult to search the target material from the recording medium because the recorded contents are not known later.
[0012]
Accordingly, an object of the present invention is to provide a video / audio material recording apparatus that can easily distinguish each recorded material even if a plurality of materials are recorded.
[0013]

Therefore, these pieces of information are automatically registered from the central processing unit 3 to the database 6.
[0043]
In this way, the incidental information of the material is registered in the database 6. The incidental information registered in this way is used, for example, in a news transmission system when a computer that manages the production of news manages the news gathering schedule. In addition, it is also used for data retrieval related to recorded video / audio signals recorded as material when editing a news program. That is, a search is performed on the incidental information of the material registered in the database 6 under a predetermined condition, and for example, a material ID is obtained as a search result. Therefore, the material associated with this material ID is searched from the materials recorded in the material recording device 2 and reproduced. Similarly, the incidental information is also used as control data for the playback device when the associated material is played back.
[0044]
By the way, the recording of news material at actual broadcasting stations is often urgent and sudden. In such a case, the coverage schedule may not be registered in advance in the database 6 as incidental information. In this case, of the supplementary information of the material, the contents of the above-mentioned fourth item to the fifteenth item, that is, information based on the material coverage schedule cannot be obtained. Further, there may be a case where the incidental information from the instruction device 5 is not directly input. In such a case, the material search operation becomes very difficult.
[0045]
Next, a description will be given of a search for a material when the contents of the fourth item to the fifteenth item, which are information based on the material coverage schedule, cannot be obtained from the incidental information of the material. First, the user checks whether or not the desired material is “the material recorded through which input line”. For example, there may be a method of making a telephone call to a news gathering place, listening to a person who actually conducted the news gathering, or asking an operator who has received the material.
[0046]
As described above, the actual recording start time, recording end time, or input line name (input line number) of the material is automatically recorded in the database 6 as incidental information of the material together with the recording of the material in the material recording device 2. be registered. In addition, a material ID that associates the material with the accompanying information is also automatically registered in the database 6.
[0047]
A plurality of materials cannot be recorded at the same time for one input line. Therefore, there is no material having the same input line name (input line number) and recording time zone. Therefore, by searching the database 6 based on the recording start time of the material, the recording end time (or recording time length), and the input line name (input line number) that transmitted the material, the material ID is obtained as a search result. Obtainable. Then, the user can obtain a desired material recorded in the material recording device 2 based on the material ID.
[0048]
【The invention's effect】
As described above, according to the present invention, the input line name (input line number) through which the material is actually transmitted and the recording start time (or recording end time) of the actual material are managed as the incidental information of the material. Automatically registered in the database. A plurality of materials cannot be recorded at the same time for one input line, and there is no material having the same input line name (input line number) and recording time zone. Therefore, with regard to the incidental information of a certain material, there is an effect that even if the information based on the material coverage schedule is missing, it is easy to obtain the material uniquely.
