The present invention relates to a VTR device capable of easily searching source image data.

[0002]

2. Description of the Related Art A home or personal VTR device is generally used by recording and reproducing desired image data of images received by a TV receiver. However, when the number of such video tape cassettes (video libraries) increases, it is difficult to easily distinguish what kind of image was recorded in which cassette.

Therefore, conventionally, a method of writing a source (recorded image data) title or the like on the side surface of the video tape cassette has been used. However, in the normal usage, it is possible to record the image data of a plurality of contents on one video tape, and even if the corresponding video tape cassette is found, the position where the image data is recorded is searched for. (Cueing operation) is not easy.

In this case, if the conventional method such as VISS or VASS is used, the cueing operation is possible, but when there is no information on the video tape side, the content of the source must be actually cueed. There was a problem that I didn't understand.
That is, in the conventional library management method, it is difficult to find a video tape cassette on which desired image data is recorded, and even if multiple sources are recorded on one tape, the beginning of the image data is recorded. If you do not search the position of, you cannot play immediately.

As described above, in the conventional method of writing on the side surface of the tape cassette, since the amount of information that can be written on the side surface of the cassette is limited, it is not possible to write all titles, and each title cannot be written. It is not easy to quickly know the content of the corresponding image or search for the start position of the image. Further, when the number of video libraries increases, there are many inconveniences such as management of the video libraries becoming more troublesome.

[0006]

SUMMARY OF THE INVENTION The present invention solves such inconvenience caused in a conventional VTR device,
The video library can be managed on the VTR device side, and the recorded position of the desired image data can be searched quickly (smooth cueing operation is enabled) to improve operability. An object of the present invention is to provide a VTR device with a library management function.

Embodiment 1 Regarding the present invention, referring to the drawings,
The embodiment will be described in detail. This embodiment mainly corresponds to the invention of claim 1, but is also related to the inventions of claim 2 and claim 3. In this embodiment, the VTR
An IC memory card detachably attached to the main body of the apparatus is used to record management information such as ID information for identifying each video tape cassette and a title of recorded image data, and based on this management information The feature is that the image data recorded on the video tape is searched.

FIG. 1 is a diagram showing an embodiment of the essential structure of a VTR device with a library management function according to the present invention. (1) is a front view of the VTR device and (2) is an upper face of an IC memory card. Figure (3) is a top view of the video tape cassette. In the figure, 1 is a video deck, 2 is a video tape cassette insertion slot, 3 is a display section, 4 is an IC memory card insertion slot, 5 is an IC memory card, and 6 is a video tape cassette.

As shown in FIG. 1 (1), the video deck 1 is provided with an IC memory card insertion slot 4 in addition to the conventional video tape cassette insertion slot 2 and display section 3. The IC memory card 5 shown in FIG. 1B is inserted into and removed from (inserted into) the IC memory card insertion slot 4.

The IC memory card 5 is a memory card for storing library management information. As described above, by making the IC memory card 5 detachable, even a memory having a relatively small capacity can handle a large amount of information by exchanging the card.

The video tape cassette 6 is shown in FIG.
As shown in (3), the external appearance is the same as that of a normal tape cassette, but as will be described later, ID data (identification information) is written in advance on the tape to enable the cueing process. 1 (1) to (3), the appearance features are that an IC memory card insertion slot 4 is provided in the VCR 1, and operability at the time of inputting information such as a title at the time of inputting or searching. 2 is different from the conventional device in that the display capacity of the display unit 3 is slightly larger than that of the conventional device in order to improve the above. The functional characteristics will be described with reference to FIG.

FIG. 2 is a functional block diagram showing an embodiment of the main configuration of the VTR device with library management function of the present invention. In the figure, 11 is a control unit, 12 is a registration deletion processing unit, 13 is a transfer processing unit, 14
Is a search processing unit, 15 is a tape ID reading unit, and 16 is I
/ O interface section, 17 is a built-in memory, 18 is a memory card, 19 is a VTR function section, 20 is a display section, and T1 to T3 are terminals.

The VTR device (video deck) shown in FIG. 2 is basically the same as the conventional device only in the VTR function section 19. By the operation of the VTR function section 19, a desired source ( (Image data) can be reserved and recorded. Although not shown in FIG. 2, this VTR device can be controlled by a remote controller (not shown) as in the conventional case, and when the remote controller is not used, the terminals T2 and T3 can be controlled.
The operation unit is connected to.

The control unit 11 has a function of controlling the entire system of the VCR shown in FIG. 2 based on an instruction from the remote controller and information reserved in the VTR function unit 19. Also, the registration deletion processing unit 1
Reference numeral 2 denotes a processing unit for recording the library management information as described above in the built-in memory 17 or the memory card 18 and for deleting the already recorded management information.

Upon receiving an instruction from the remote controller, the transfer processing unit 13 receives the internal memory 17 and the memory card 1.
8 has the function of transferring management information to and from
Information is exchanged via the I / O interface section 16. The search processing unit 14 has a function of searching the management information recorded in the built-in memory 17 or the memory card 18.

The tape ID reading section 15 has a function of reading the tape ID (tape identification information) written on the side surface of the tape cassette (6 in FIG. 1) set in the video deck. ing. The display unit 20 is a display unit similar to the conventional one, except that a display unit having a large display capacity is used.

When a video tape cassette is inserted into the VTR device shown in FIG. 2, the tape ID reading unit 15 first reads the ID data written on the side surface of the tape cassette and instructs the search processing unit 14. To identify the video tape cassette (video tape). Further, as already described, this system is configured so that, in the case of recording reservation, information such as the date, recording start time, end time, and channel, as well as the conventional information, as well as information such as the title of the image data can be input. (Described in detail in FIGS. 4 and 5 below).

At the same time when the reserved recording operation is started, these management information, tape ID information, and cue ID
Information is stored (registered) in both the built-in memory 17 and the memory card 18 via the I / O interface section 16. When the memory card 18 is not inserted, it is recorded (registered) only in the built-in memory 17.

The recording operation of the management information in the memory card 18 or the built-in memory 17 is automatically executed at the start of the reserved recording operation, but when the recording is performed by the manual operation, the necessary management information is recorded thereafter. It is a configuration that allows registration of. Further, if information that is not added as a reservation function, for example, information such as a recording date (or date) is required, that information is also input.

Next, the operation of the VTR device with the library management function of the present invention will be described. When a tape is inserted into the VCR of FIG. 2 during playback (when a video tape cassette is loaded), the tape ID information is read and the memory card 1 is read by the ID information.
The management information registered in 8 is searched. Then, the information of the search result is displayed on the screen of the display unit 20.

When the user selects a desired source while scrolling the screen using the table (search result table) displayed on the display unit 20, the cue ID information is referred to perform cueing. , The image data is reproduced from that position (the invention of claim 3). In this case, if the screen of the TV receiver is used, it is possible to display a list of search result information.

When the user selects / indicates a desired source using the table displayed in the list, the cue ID is similarly set.
Information is referred to perform cueing, and image data is reproduced from that position. As described above, when the screen of the TV receiver is used, the information such as the title is displayed at one time on the same screen, so that the contents of the library become obvious.

Cue ID information can be written on the tape (the cue ID information will be described in detail later). Further, when the memory card 18 has an excessive storage capacity, it can be dealt with by replacing it with a new memory card.

At this time, from the viewpoint of library management, there may be a case in which it is desired to transfer the information in the card whose capacity has exceeded the capacity to another card. In that case, the built-in memory 17 is used to transfer the management information.

First, the management information (data group) to be transferred is selected and temporarily saved in the built-in memory 17. Then, after the card is replaced with a card to be recorded (new memory card), recording is performed from the built-in memory 17 to the new memory card.

Therefore, the built-in memory 17 has two functions of temporary information management and transfer buffer. The control unit 11 selects and controls various functions as described above. By managing the library information on the deck body side in this way, not only is it unnecessary to write a title on the side surface of the tape cassette, but also cueing can be performed smoothly, so that operability is improved.

FIG. 3 is a diagram showing an example in which ID information is added to the video tape cassette used in the VTR device with the library management function of the present invention. (1) is a bar code, (2) character Indicates the case of a character string.

As shown in FIGS. 3 (1) and 3 (2), a bar code or a character string can be used as the ID information (identification information) displayed on one side of the video tape cassette. . In the case of barcode, VT
A bar code reader is required for the main body of the R device, and in the case of a character string, OCR (Optical Character Reader
r) is required.

When any of the ID information is used, the tape ID reading unit 15 shown in FIG.
Reads the ID information and recognizes (identifies) the set video tape cassette. The reason for displaying the ID information on the video tape cassette in this way is to recognize the ID information quickly. However, the ID information (display position and contents) used in this case is used when the tape is manufactured. It is necessary to determine, and since it differs between the case of a bar code and the case of a character character string, and its position also becomes a problem, it is desirable to adopt the unified format in any case.

It is also possible to use a sticker on which ID information such as a bar code or a character string is printed at a predetermined position of the video tape cassette as a video cassette for displaying ID information. If the method using this sticker is adopted, even a video cassette that has already been used can be used as a video cassette for displaying ID information.

As described above, in the VTR device with the library management function of the present invention, ID information for identifying each video tape cassette, recording date and time of image data recorded on the video tape, channel, title. The management information such as is recorded in a detachably configured IC memory card so that desired image data can be quickly and easily searched for when the tape is reproduced based on the information. Also, for image data recorded in the middle of the tape, by using so-called cue ID information, a desired source image (recorded image data) can be easily and accurately reproduced (second). The example will be described).

As shown in FIG. 5 (1), when setting the start time of reserved recording, "reservation number", "day of the week", "start time", "channel", and "mode" are input. After registering on the VTR device main unit side with the "Reserve" key, the "End time" is set and registered as shown in FIG. 5 (2), but in this state, only the reserved recording end time can be set. The above operation is the same as the conventional reserved recording method.

As described above many times, in the present invention, the program title name and the like can be subsequently input, which is used for searching the video library and for finding the beginning. FIG. 5 (3) shows a display screen when a program title name or the like is input. After the program title name or the like is input by a character string of katakana, it is registered in the VTR device main body side by the "register" key.

[0066]

Second Embodiment Next, a second embodiment will be described. This embodiment mainly corresponds to the invention of claim 2, but is also related to the inventions of claims 1 and 3 above.

In the above embodiment, the IC memory card 5 shown in FIG. 1 is used to record the library management information.
When the video tape cassette is set, the IC memory card 5 is used to record, for example, the day of the week, the recording start time, the recording end time, the channel, the recording mode (standard, triple, etc.) of the recording set at the time of reservation. This is a case where management information corresponding to a tape cassette such as a title is displayed so that necessary image data can be searched. The second embodiment is characterized in that such management information enables the cueing operation of the image data recorded in the middle of the video tape.

In order to perform such a cueing operation, in the second embodiment, a cueing ID (hereinafter referred to as a cueing ID) is set on the video tape incorporated in the video tape cassette on the VTR device main body side in FIG. , Cue ID information) is recorded (invention of claim 2), and at the time of searching for image data, the position is detected by this cue ID information and a desired image is reproduced (invention of claim 3). . The cue ID information (identification information) is information for searching an intermediate position on the video tape, and numeric data (binary code) or the like is recorded on the tape at equal intervals.

The cue ID information is also recorded on the IC memory card 5 as one of the library management information. Therefore, this cue ID information does not need to be recorded in advance when the video tape is manufactured, but may be recorded when the video tape is first set in the VTR device.

For example, when the video tape cassette is set in the VTR device, the VTR device body detects the presence or absence of the cue ID information on the video tape, and if the cue ID information is detected within a certain section. If not, it is determined that the cassette is a new video tape cassette, and the cue ID information is recorded on all the tapes. Instead of recording the cue ID information at equal intervals, it is also possible to record the same numerical data or character data at the recording start position at the start of recording.

In the case of this recording method, there is an advantage that the search time for the cue ID information is shortened as compared with the previous method of recording the cue ID information at equal intervals. But,
When the user records image data of any length (time) at any position, some or all of the previously recorded images will be erased and rewritten with new image data. Processing becomes complicated and cue ID
There is a problem that it takes time to retrieve information.
