Abstract

PURPOSE:To send a CM into 2-systems while realizing the system at a low cost with saved space. CONSTITUTION:A video file device 3 using a magneto-optical disk stores CM data to be sent. When the file device 3 is not in use, a video signal changeover device 5 is thrown to the position of a contact (b) and part of stored data (CM data scheduled to be sent) are stored in a video file device 4 using a semiconductor memory. The stored data in the video file devices are sent under the control of the CM transmission controller in response to an external command. Since the file device 4 using the semiconductor memory is used, the file device employing the magneto-optical disk is sent to two systems at a lower cost and a more saved space than a duplicated configuration.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic CM (commercial) transmission system, and more particularly to a system used in a television broadcasting station for transmitting different CMs simultaneously and a system for performing simple dual direct transmission.

[0002]

2. Description of the Related Art Generally, when a CM is transmitted from one broadcasting station, it may be desired to transmit different CMs for each service area. For example, there are cases where it is desired to send different CMs (for example, national version and local version) to two service areas, and in such a case, it is necessary to send two systems.

A conventional automatic CM sending system has a video file device in which CM materials are stored, and CM materials (CM data) are read and sent in response to an external command. The video file device is generally constructed using a magneto-optical disk.

Since the conventional system has only one video file device, the same CM cannot be transmitted at the same time when two systems are transmitted.
For example, as shown in FIG. 7, CM-A, CM-B and CM-C are sent to the sending line A, and CM-D, CM-B and CM-E are sent to the sending line B. Considering the case of sending a CM-B, the start time is slightly different
Material may be used for both delivery line A and delivery line B. Therefore, it is necessary to prepare two video file devices that store the same CM material.

The conventional automatic CM sending system will be described with reference to FIG. Referring to FIG. 5, the conventional C
The M automatic transmission system 10 is configured to include two video file devices 3 and 30 that store CM materials, and a CM transmission control device 2 that controls reading of the video file devices 3 and 30. The CM is sent in response to the CM sending data 6 for sending the CM and a command from the automatic program control device 1.

The same CM material is stored in the two video file devices 3 and 30, and when the CM material 8 is additionally written, the CM material 8 is also written in the same manner, and the same stored content is always obtained. Has become.

According to this structure, it is possible to send out two systems of CM material as shown in FIG.

On the other hand, in the automatic CM sending device, when direct sending is performed, there is a case where the system is constructed in consideration of reliability in order to send in real time so that equipment failure does not lead to on-air failure. Also in this case, two video file devices were required.

The conventional CM automatic transmission system will be described with reference to FIG. Referring to FIG. 6, the conventional C
The M automatic transmission system is configured to include two video file devices 3 and 30 as in the case of FIG. 4, and performs dual transmission from these devices. That is, normally, by setting the switch of the dual video switching device 7 to the contact c side, the video file device 3 to C
M is sent. Then, when there is some abnormality in the video file device 3, the switch of the selector 7 is manually operated and the CM is sent as a video signal from the video file device 30 to the sending line C by setting the contact d side.

In other words, the reliability of on-air is improved by such a dual structure.

[0011]

In the conventional CM automatic transmission system described above, two video file devices using a magneto-optical disk were required when performing two-system transmission and dual transmission. A video file device using a disk needs to store many CM materials in order to store all CMs to be sent. Therefore, there is a drawback that a large storage capacity is required, it is expensive, and a large space is required for installation.

Further, a video file device using a magneto-optical disk requires a robot for automatically loading a recording / reproducing device for a storage medium storing CM data. This robot is a machine. There are many parts, and there is a drawback that it is less reliable than an electric circuit.

The present invention has been made to solve the above-mentioned conventional drawbacks, and an object of the present invention is to provide an automatic CM transmission system capable of realizing two-system transmission and dual transmission at low cost and in a small space. .

[0014]

In order to solve the above problems, an automatic CM sending system according to the present invention comprises a first video file means in which CM data to be sent is stored.
When the first video file means is not used, the second video file means for storing a part of the storage data thereof and the storage data of the first and second video file means are provided in accordance with an external command. And a sending means for sending out.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a first embodiment of an automatic CM sending system according to the present invention, and the same portions as those in FIG. 5 are designated by the same reference numerals. 5 is different from the system shown in FIG. 5 in that a video file device 4 using a semiconductor memory is provided instead of the video file device 30 using a magneto-optical disk, and a video that can be switched to the idle time of the file device 3. The point is that the signal switch 5 is provided. This configuration is a configuration in which two systems are transmitted.

Generally, the CM transmission is performed in units of several minutes between programs, as shown in FIG. That is, the A program and the B program in FIG. 3 have a front CM, a middle CM, and a rear CM, respectively, and are C only for the period of the double line portion in the figure.
M will be sent.

Therefore, the video file device using the magneto-optical disk operates only for a few minutes for the CM transmission, and is inactive for most of the time.

Therefore, in this embodiment, by utilizing this free time, a plurality of CMs to be transmitted in the future are stored in advance in a video file device using a semiconductor, and the C
When it is time to actually transmit the M data, the CM transmission control device 2 controls the CM file transmission using the magneto-optical disk and the semiconductor video file device at the same time.

Returning to FIG. 1, in the CM automatic sending apparatus of the present embodiment having such a configuration, the CM sending control apparatus 2 controls the video signal switching unit 5 to the contact b side while the CM sending is not performed. . Then, based on the CM transmission data 6 inputted in advance, C which is to be transmitted from the transmission line A in the future.
The M data is reproduced by controlling the video file device 3 using the magneto-optical disk. The reproduced CM video signal passes through the video switch 5 and is input to the video file device 4 using a semiconductor memory and recorded in the internal semiconductor memory. This process is repeated until the memory in the video file device 4 is full while the CM is not being sent.

When it is time to actually send the CM, the automatic program control apparatus 1 outputs a CM sending start signal to the CM sending control apparatus 2 based on the CM sending data 6 input in advance.

When the CM sending control device 2 receives the start signal and is storing the CM in the video file device 4, this process is interrupted to control the video signal switching device 5 to the contact a side, The CM data transmitted from the transmission line A from the video file device 3 is reproduced. Played C
The M data is transmitted from the transmission line A through the video switch 5. Also, the CM data sent from the video file device 4 to the sending line B is reproduced, and the reproduced CM data is sent from the sending line B.

As described above, different CM data can be simultaneously transmitted from the transmission lines A and B.

It should be noted that the CM transmission control device 2 uses the continuous C
When the M data transmission process is completed, the CM whose transmission is completed from the transmission line B stored in the video file device 4 is completed.
The data is cleared and the CM to be newly transmitted is stored from the video file device 3.

On the other hand, FIG. 2 is a block diagram showing the configuration of the second embodiment of the automatic CM sending apparatus according to the present invention.
6, and the same parts as those in FIG. The difference from the system shown in FIG. 6 is that a video file device 4 using a semiconductor memory is provided in place of the video file device 30 using a magneto-optical disk, and a video that can be switched to the free time of the file device 3 is provided. The point is that the signal switch 5 is provided. In this case, the storage capacity of the video file device 4 using a semiconductor requires at least a capacity (3 to 4 hours) for storing CM data to be sent in one day. Even in the case of performing the simple dual transmission according to this example, the control performed by the CM transmission control device 2 is the same as in the case of performing the above-described two-system transmission, and therefore the description thereof will be omitted and only the transmission system will be described.

First, the CM data reproduced from the video file device 3 using the magneto-optical disk passes through the video switching device 5 and is input to the duplex video switching device 7. Similarly, the CM data reproduced from the video file device 4 using the semiconductor memory is also input to the duplex video switcher 7. Then, in the normal state, the file device 4 sends a CM.

If an abnormality occurs in the video file device 4 using the semiconductor memory and the CM is not reproduced correctly, the operator manually switches the duplex video switch 6 from the contact d side to the c side, and the magneto-optical disk. The CM data reproduced by the video file device 3 using is transmitted. As a result, even if a device failure occurs, normal CM data can be sent without causing an on-air failure.

The above operation will be described with reference to FIG.

FIG. 4A shows the states of the switches 5 and 7 when the CM transmission is not performed. In this case, the video file device 3 originally using the magneto-optical disk is not used for CM transmission. Therefore, in such a case, the video signal switch 5 is set to the contact b side, and a part of the CM data that is the storage data of the file device 3 (a part to be transmitted) is stored in the video file device 4 using the semiconductor memory. Remember.

Then, as shown in FIG. 3B, when the CM is transmitted, the switch 5 is switched to the contact a side and the switch 7 is set to the contact d side. This is because the CM data is transmitted from the file device 4 in the normal state. Then, when an abnormality occurs in the file device 4, the switching device 7 is manually operated to switch to the contact c side, and the CM is transmitted from the file device 3.

The operation of the switching device 7 may be reversed from the above case during normal times and during abnormal times, and CM data may be sent from the file device 3 during normal times.

Further, although the video file device using the semiconductor memory is used in the first and second embodiments, the invention is not limited to this, and various file devices can be used as long as the cost and space can be reduced. Equipment available. For example, a file device using a known magnetic tape may be used.

[0033]

As described above, according to the present invention,
Even in an automatic CM sending device having only one video file device using a magneto-optical disk, different CM data to be sent to two systems can be stored by storing different CM data to be sent in advance in a video file device using a semiconductor memory. Can be sent.

Further, when the same CM data is stored in a video file device using a magneto-optical disk and a video file device using a semiconductor memory and reproduced at the same time, an abnormality occurs in one of them. ,
By switching between these two video signals, a normal C
There is an effect that M data can be transmitted.

Furthermore, since the video file device using the semiconductor memory has few mechanical parts, there is an effect that the reliability can be remarkably improved.

Further, since the video file device using the semiconductor memory only needs to store a part of the stored data in the video file device using the magneto-optical disk, it requires only a small capacity and can be constructed inexpensively and compactly. Therefore, there is an effect that the system can be configured while reducing the cost and saving the space.
