Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium used in a case where a tape-shaped recording medium such as a video cassette tape is accommodated in a case. The present invention relates to a cassette label that can be recorded and a video cassette tape to which the cassette label is attached.

[0002]

2. Description of the Related Art There is a demand for recording and storing video data which is photographed by an image pickup device such as a television camera and recorded on a video tape in such a manner that information such as its contents can be easily confirmed. . Especially,
In the case of a television broadcast station used for news gathering, a necessary cut is quickly selected from a large number of cuts (consecutively shot images or video data) shot by a video camcorder or the like. Need to be edited.

Until now, usually, such information of recorded video data is recorded in a separate memo at the time of shooting, and at the time of reproduction or editing, desired video data is selected at a high speed while viewing the memo. Such a method is used. In a system for automatically handling a large number of video cassettes such as a cassette library, video cassette tapes are managed using a cassette label on which a barcode is printed.

In recent years, in a 1/4 inch digital video cassette tape or the like, a semiconductor memory device such as a flash memory is incorporated in a cassette for accommodating a video tape so that information such as recording time, recorded contents, and title can be recorded. Some are. The recording and reproduction of data with respect to the semiconductor memory device incorporated in such a video cassette tape are provided, for example, near the erroneous erasure prevention tab on the back of the cassette case. This is performed by a contact method via an electrode composed of:

[0005] However, such a conventional method has limitations and inconveniences in various forms of use.
For example, in a method of taking a memo on paper, the paper may be lost, or processing based on the memo cannot be automated. In a method of printing a barcode on a label, the amount of information that can be recorded is limited and not sufficient. In addition, in the method using a semiconductor memory, there is a problem that the electrodes must be brought into appropriate contact with each other and the positioning thereof must be performed with high accuracy, and a problem of poor contact due to adhesion of dust or the like. In addition, for an enormous amount of video cassette tapes, such as hundreds of thousands of television broadcast stations where video data has already been recorded, the information of the recorded video data is digitized and held. There is also a problem that these methods are not appropriate for doing so.

Accordingly, the present inventors have already disclosed in Japanese Patent Application No. Hei.
A cassette label that accommodates an integrated circuit such as a semiconductor memory and that can transfer data to the outside by a non-contact method as proposed in Japanese Patent Application No. 300449 is proposed. If the additional information of the video data recorded by the cassette label is managed, the various problems as described above can be solved. Further, the present invention can be easily applied to a video cassette tape on which video data is already recorded.

The cassette label will be described with reference to FIG. FIGS. 5A and 5B are diagrams showing the configuration of the cassette label 8, in which FIG. 5A is a top view and FIG. 5B is a side view.
As illustrated, the cassette label 8 is formed by burying an IC 20 and an antenna 30 in a label base 10. The label base 10 is formed by applying a double-sided adhesive 17 to the side of the label body 11 to be attached to the video cassette tape, and further covering the double-sided adhesive 17 with a release paper 18. When the label body 11 is adhered to the video cassette tape, the label paper 11 is adhered to the video cassette tape by the double-sided adhesive 17 by peeling the release paper 18.

The surface of the label body 11 opposite to the surface to which the double-sided adhesive 17 has been applied, that is, the surface that becomes the surface when affixed to a video cassette tape is an entry surface 111. The information, such as the title of the video data recorded at the time, the recording date and time, and the recording location, can be described. As shown, the IC 20 is disposed at the longitudinal end of the cassette label 8, and the antenna 30 is disposed at the center of the cassette label 8, and they are connected by a part of the antenna 30.

[0009]

However, even with such a cassette label, it is desired to increase the amount of information that can be recorded on the cassette label, in other words, the amount of data that can be recorded on an IC contained in the cassette label. There is a request. For example, if this cassette label is applied to a video cassette tape on which video data is recorded by a camcorder or the like, many time codes are recorded as a good shot marker, and in addition to this, the equipment number, the photographer, and the shooting location , Take number, date and time, and comments on each of the cuts. There is also a demand for recording various items and information.

However, ICs accommodated in cassette labels are limited in size and in terms of mounting technology, and therefore are usually about 2 KB, and there is a demand for recording such various information. It was not enough capacity to answer. Therefore, when new information is to be additionally recorded, since the capacity is insufficient, it is necessary to take measures such as erasing and recording the already recorded information, and the usability is deteriorated.

Accordingly, an object of the present invention is to provide a cassette label which can record a large amount of information and can appropriately record desired information even when a large number of cuts are recorded. Another object of the present invention is to
A larger amount of information can be recorded on the cassette label of the IC housing mounted on the back surface, and even when a large number of cuts are recorded, desired additional information can be appropriately recorded on the cassette label. To provide a video cassette tape.

[0012]

In order to solve the above-mentioned problems, a plurality of ICs are accommodated in a cassette label to increase the recording capacity of the cassette label without developing a new highly integrated IC. I did it. In addition, as the plurality of ICs, at least independently operable ICs having substantially the same function are used, and IDs are assigned to the plurality of ICs, thereby selecting one of the ICs. It was enabled and used. As a result, the wiring in the cassette label only needs to connect the respective ICs and the antenna, and the plurality of ICs can be used with a simple configuration and a simple communication method as before.

Accordingly, the cassette label of the present invention
A plurality of integrated circuits having a storage unit and a signal processing unit; antenna means for transferring at least a signal to the integrated circuits; and housing the plurality of integrated circuits and the antenna means, mounted on the back of a video cassette tape And a label substrate. Preferably, the plurality of integrated circuits are substantially the same integrated circuits each having an identification code for specifying each integrated circuit, and one integrated circuit based on the identification code is used by the plurality of integrated circuits. Is selected and validated, and the validated integrated circuit transfers a signal via the antenna means.

Also, the video cassette tape of the present invention
A video tape for recording a video signal, a cassette case accommodating the video tape, a plurality of integrated circuits mounted on the back of the cassette case and having a storage unit and a signal processing unit, and at least a signal to the integrated circuit. And a cassette label having the integrated circuit and a label base accommodating the antenna means.

Next, the ICs 20a and 20b and the antenna pattern 30 will be described. Two ICs 20a, 20
b denotes an integrated circuit having a memory unit and a signal processing unit, each of which can store and hold data, and is an IC having substantially the same configuration and the same function. ID codes are assigned to these two ICs 20a and 20b, and are recorded in a recording unit in the ICs 20a and 20b. When a signal is transferred to an external device, a process is first performed to determine which of the two ICs 20a and 20b is to be enabled based on the ID code. Any one of the ICs substantially transfers signals with an external device. Note that this effective IC is appropriately changed while performing signal processing with an external device.

In this embodiment, the IC 20
Each of a and 20b has a memory with a storage capacity of 2 Kbytes. That is, the cassette label 1 can store 4 Kbytes of information. Further, the ICs 20a, 20
The signal processing units provided in b each are processor units that operate with a clock of 13 MHz, and perform processing such as reading / writing data to / from each built-in memory and transferring data to / from an external read / write module via the antenna 30. I do.

The antenna 30 is an antenna for supplying power and transferring signals without a contact between the cassette label 1 and the external read / write module. It consists of a connection line connecting the antenna body and the two ICs 20a and 20b.

Next, a usage mode and an application mode of the cassette label 1 will be described with reference to FIGS. FIG. 3 is a diagram showing a state in which such a cassette label 1 is attached to a video cassette tape 2. As shown in FIG. 3, the cassette label 1 is peeled off from the release paper and adhered to the concave portion 54 formed according to the label shape on the back surface of the video cassette tape 2 by the double-sided adhesive 17.
At this time, the direction of the cassette label 1 may be arbitrary. Since the antenna 30 of the cassette label 1 is provided near the center of the cassette label 1, the concave portion 54 of the video cassette tape 2 can be attached to the cassette label 1 in any direction.
The antenna 30 comes near the center of the external read / write module, and the external read / write module may perform communication by arranging the external antenna near the position.

An arbitrary figure such as a character or a picture is written on the surface of the cassette label 1 with an arbitrary writing tool, and is used for identification of the video cassette tape 2 and the like.
The characters written on the surface of the cassette label 1 may be written before the cassette label 1 is attached to the video cassette tape, or may be printed in advance.

FIG. 4 shows a usage form of the video cassette tape 3 to which the cassette label shown in FIG. 3 is attached. FIG.
FIG. 3 is a diagram showing a state in which the video cassette tape 3 with the cassette label mounted is mounted on a video tape recorder (VTR) device, and data is transferred to the ICs 20a and 20b in the cassette label 1. As shown in FIG. 4, when the video cassette tape 3 on which the cassette label is mounted is mounted on the VTR device, the cover 55 on the surface portion
Is opened, a video tape (not shown) stored in the video cassette tape 3 is pulled out, and is brought into contact with the head of the video data recording / reproducing apparatus.

On the other hand, near the center of the back surface of the video cassette tape 3, an antenna 9 output from a label read / write module 91 provided in the main body of the VTR device is provided.

As described above, in the cassette label 1 according to the present embodiment, just like the conventional cassette label, some graphics are described on the surface and the video is attached to the video cassette tape 2 and In addition to being able to use the cassette tape for identification and content recognition, various data can be recorded in the ICs 20a and 20b provided therein. In other words, recording conditions that have been written down on separate sheets as memos,
Information relating to the recorded contents can be electronically recorded on the cassette label 1. In particular, in the cassette label 1 of the present embodiment, two ICs 20
a, 20b, so one IC so far
It is possible to record twice as much information as compared to the cassette label 1 containing only the information.

Since the antenna 30 is located near the center of the cassette label 1, no matter which direction the cassette label 1 is attached to the video cassette tape 2, the antenna 30 is always located near the center of the concave portion 54 of the video cassette tape 2. Will come. That is, cassette label 1
May be attached to the video cassette tape 2 in any direction. In addition, since the data transfer to the ICs 20a and 20b is performed by a non-contact method, there are no problems such as a poor contact position and a poor contact due to dust or wear, and the reliability is high, the life is long, and the Recording of additional information. In addition, the cassette label 1 according to the present embodiment can be attached to an existing video cassette tape on which video data has already been recorded, and is suitable for use in management and the like. .
