This will be described with reference to a flowchart. The AV content 1 stored in the HDD 31 (content database 92)
01 is generated from the image and sound dubbed on the video tape cassette 10 (FIG. 1),
Here, a case will be described as an example where the two-dimensional barcode printed on the label 11 is registered in association with the AV content 101.

That is, the label 11 attached to the video cassette 10 is imaged by the DVCR 5, and the resulting image (the image including the two-dimensional barcode printed on the label 11) is transmitted via the network 7. And supplied to the personal computer 1. At that time, in step S11, the AV content management / retrieval program 82 fetches the image and proceeds to step S11.
At 12, the two-dimensional barcode contained in the image is recognized. Specifically, a two-dimensional barcode number is detected from the image.

At this time, the CRT 30 has, for example,
As shown in FIG. 10, a two-dimensional barcode recognition screen on which a two-dimensional barcode image is displayed is formed.

Next, in step S13, the AV content management and retrieval program 82 stores the two-dimensional barcode number of the two-dimensional barcode printed on the label 11 detected in step S12 in the content database 92. The content is additionally stored in the AV content attribute record 102 of the current AV content 101. As a result, the AV content attribute record 102 includes FIG.
As shown in (A), a two-dimensional barcode number is stored. Thereafter, the process ends.

As described above, the two-dimensional bar code printed on the label 11 of the video tape cassette 10 corresponds to the AV content 101 (video tape cassette 10).
Is registered in association with AV content generated based on the image and sound dubbed into the content.

Next, a process of presenting the contents dubbed to the video tape cassette 10 to the user using the two-dimensional barcode registered by the two-dimensional barcode registration process (hereinafter, referred to as an AV content search process). ) Will be described with reference to the flowchart in FIG. 11.

When the user operates the personal computer 1 and instructs the AV content management search program 82 to start the AV content search processing, the AV content management search program 82 proceeds to step S21 as shown in FIG. Screen (initial screen), CR
It is displayed on T30.

In the thumbnail image display window 201 on the initial screen, a thumbnail image corresponding to the AV content searched for in the processing described later is displayed. At this point, no AV content has been detected, and nothing is displayed in the thumbnail image display window 201.

[0062] In the attribute information display window 202, predetermined AV content attribute information of the AV content searched for in the processing described later is displayed. At this point, no AV content attribute information is displayed in the attribute information display window 202.

At 05, an icon of the AV content in which the classification corresponding to the icon active in the AV content classification display window 204 is set is displayed.
In the case of this example, on the initial screen of the AV content search processing, as shown in FIG. 12, "temporary storage" displayed in the AV content classification display window 204.
Are activated, and icons corresponding to AV contents classified as “temporary storage” are displayed in the AV content icon display window 205. In the example of FIG. 12, a predetermined television broadcasting station A is displayed in the AV content icon display window 205.
Icons corresponding to the AV contents generated when recording the broadcast from D to D are displayed.

Next, in step S22, the user picks up an image of the two-dimensional barcode printed on the label 11 attached to the video tape cassette 10 with the DVCR 5, and the image obtained as a result of the shooting is displayed on the network. 7 to the personal computer 1 via the
The content management search program 82 fetches the image, and in step S23, retrieves the 2
Recognize dimensional barcode images. That is, a two-dimensional barcode number is detected.

In step S 24, the AV content management / retrieval program 82 searches the content database 9
2, the two-dimensional barcode number stored in the AV content attribute record of the predetermined AV content is read, and in step S25, the read two-dimensional barcode number matches the two-dimensional barcode number detected in step S23. In other words, it is determined whether or not the recognized two-dimensional barcode is registered in association with the AV content. If it is determined that the two-dimensional barcode matches (is registered), step Proceed to S26. In this example, when the two-dimensional barcode number stored in the AV content attribute record 102 of the AV content 101 is read, the process proceeds to step S26.

In step S 26, the AV content management / retrieval program 82 activates and displays the icon corresponding to the AV content (the AV content 101 in this example) associated with the binary barcode, It requests the recording / playback program 81 to display a thumbnail image of the AV content (AV content 101). As a result, the recording / reproducing program 81 causes the still image stored in the still image data file 112 of the AV content 101 to be displayed in the thumbnail image display window 201 as a thumbnail image.

FIG. 13 shows an icon of the activated AV content 101 and a thumbnail image of the AV content 101 reproduced and displayed. The thumb mail image displayed in the thumbnail image display window 201 is actually the AV content 1
A plurality of still images stored in the still image data file 112 are sequentially reproduced and displayed in a predetermined order. In this example, the AV content 101 is “
13 is active, the icon of "drama" displayed in the AV content classification display window 204 of Fig. 13 is active, and the AV content icon display window 205 is classified as "drama". The icons corresponding to the other AV contents A and B are displayed in an inactive state.

If it is determined in step S25 that the two-dimensional barcode numbers do not match, step S27
The AV content management search program 82 proceeds to
It is determined whether or not all the two-dimensional barcode numbers (two-dimensional barcode numbers of all registered two-dimensional barcodes) stored in the AV content attribute record of the V content have been read out, and none have been read out. If the determination is affirmative, the process proceeds to step S28, where the two-dimensional barcode number stored in the AV content attribute record of the other AV content is read from the content database 92, and the process returns to step S25 to execute the subsequent processes.

If it is determined in step S27 that all the two-dimensional barcode numbers have been read, the process proceeds to step S29, where the AV content management search program 8
2 causes the CRT 30 to display a message indicating that the AV content associated with the two-dimensional barcode recognized in step S23 is not recorded.

In step S26, the AV searched for
The process ends when the thumbnail image of the content is reproduced and displayed, or when an error message is displayed in step S29.

As described above, the thumbnail image of the AV content associated with the two-dimensional barcode is reproduced and displayed. The user can refer to the thumbnail image to display the thumbnail image of the video tape cassette 10. The content of the content dubbed (recorded) can be easily grasped.

Next, the operation of the CPU 21 (AV content management search program 82) for executing a process of creating a label on which a two-dimensional barcode is printed (hereinafter, referred to as a label creation process) will be described.

When the user operates the personal computer 1 and instructs the AV content management search program 82 to start the label creation process, the AV content management search program 82 executes a two-dimensional bar search as shown in FIG. An input screen 301 having an input field 311 for inputting a code number is displayed on the CRT 30. Thus, the user operates the keyboard 28 or the mouse 29 to input the two-dimensional barcode number of the two-dimensional barcode to be printed on the label in the input field 311.

Next, the AV content management / retrieval program 82 causes the CRT 30 to display a template selection screen 321 displaying a file storing a label (label design) template as shown in FIG. Thus, the user operates the keyboard 28 or the mouse 29 to select a desired template.

Then, as shown in FIG. 16, the AV content management search program 82 displays a two-dimensional barcode corresponding to the two-dimensional barcode number previously input by the user in a two-dimensional barcode display window 332. The CRT 30 displays a label creation screen 331 that is displayed and displays the template previously selected by the user in the template display window 333.

In the example of FIG. 16, the template display window 333 displays the template of the label of the video tape cassette. The template A includes a label attached to the side of the video tape cassette (label 1 attached to the video tape cassette 10 in FIG. 1).
The template B is a template of the back of the video tape cassette (the video tape cassette 1 in FIG. 1).
In the state of 0, it is a template of a label attached to the lower surface).

Thus, the user operates the mouse 29 or the like to drag the two-dimensional barcode displayed in the two-dimensional barcode display window 332 to a desired position of a desired template (FIG. 17). In the example of FIG. 1, the size of the dragged two-dimensional barcode is adjusted (FIG.
8) Design the label by doing, for example. Further, the user operates the keyboard 28 and the like, and inputs, for example, the title of the content as memo information. Thereby, for example, as shown in FIG. 19, the inputted memo information (indicated by “xxx” below the template A in the figure) is displayed at a predetermined position of the template.

As described above, since the label on which the two-dimensional barcode is printed is designed, the label can be easily generated by printing out the label with a predetermined printer.
