Is a still image database, 206 is a moving image database, 207 is a text (character data) database,
Reference numeral 208 denotes a voice database.

In the multimedia file 202,
Reference numeral 220 indicates that image data named “image 1” is stored. Reference numeral 221 indicates that text data named “text 1” is stored. Reference numeral 222 indicates that image data named “image 2” is stored. Reference numeral 223 indicates that audio data named “Sound 1” is stored. Reference numeral 224 indicates that audio data named “sound 2” is stored.

On the display screen 203, reference numeral 210 denotes a field 1, which is a display area of "image 1" (220). A field 211 is a display area for "text 1" (221). A field 3 is a display area for “image 2” (222). 213 is a field 4 "Sound 1"
This is an area for specifying (223). Reference numeral 214 denotes a field 5, which is an area for specifying a sound output of "sound 2" (224).

The operation of the configuration shown in the figure will be described. The multimedia data processing device 201 extracts data specified as a material constituting the multimedia file 202 from the material data storage unit 200. Then, it associates the designated field of the display screen with it and stores it in the multimedia file 202. In the case of the figure, field 1
(210) corresponds to image 1 and field 2 (21

The operation of the basic configuration (registration processing) shown in FIG. 1 will be described. A multimedia file 5 is stored in the material data storage unit 4.
Image data (images 1 and 2) such as still images and moving images, text data (text 1 and text 2), audio data (sound 1 and sound 2), etc., which are used as materials for creating.

Next, the operation will be described by taking as an example the case where image 1, text 1, and sound 1 are associated with field 1. A field area is set in the display screen example 1 by the creation data designating device 2. Similarly, from the material data stored in the material data storage unit 4, the image 1, text 1, and sound 1 to be filed in the multimedia file 5 are specified by the creation data specifying device 2.
The designated material data (image 1, text 1, sound 1) is taken into the storage area of the multimedia data processing device 3.

Management information creating section 16 of item creating section 15
Creates an item object 1 (20), an image object 21, a text object 22, and a sound object 23 in the field 1. That is, management information such as the number of data managed by the field 1 is set in the header portion of the item object 1 (20). In the data area, object information such as an address of the image 1, text 1, and sound 1 in the storage device and a file address of the multimedia file 5 are set. And the image 1 has a multimedia data file 5
Image 1 by adding management information such as the file address of
Object 21 is created. Similarly, an object 22 of text 1 is created by adding management information to text 1. Further, an object 23 of the sound 1 is created by adding management information to the sound 1.

Further, the item management table creating unit 17
Are the created objects (item object 1 (20), multimedia data objects 21,
The item management table 19 is created based on management information of other fields such as 22, 23 and field 2).

The item management table 19 has, for each field, pointers such as an item object managed by the field, an address of the multimedia data object on the storage device, and an address of the multimedia file 5. The item object 1 (20) has a pointer such as the address of the multimedia file 5 of the object of the multimedia data to be managed by the field 1. The image object 21, the text object 22, and the sound object 23 are respectively
It has a pointer such as the address of the multimedia file 5.

For example, when the field 1 is designated, the item management table 19 is referred to and the item object 1 (20) is designated by the pointer. And
The object 21 of the image 1 is designated by the pointer of the object information of the image 1.

The item storage processing unit 18 includes an item management table 19, an item object 1 (20), an image 21 object 21, and a text 1 object 2
2. The object 23 of the sound 1 and the like are stored in the multimedia file 5. At this time, each object holds the file address of the multimedia file 5 and is stored at each file address of the multimedia file 5.

The operation of the basic configuration (2) shown in FIG. 2 will be described. When a field is designated by the execution instruction device 30, in the multimedia data processing device 31, the item management table reference section 40 refers to the item management table 41. The processing determination unit 42 is configured to store the item management table 41
The item object corresponding to the field specified by is obtained, and the object of the multimedia data managed by the specified field is obtained from the object information. Then, the process-specific determination unit 42 determines the number of data to be managed by the designated field, and if there is only one data to be managed, the data type determination unit 44 determines the type of the designated data. For example, in the case of an image (still image), an image output unit (still image) 5
1 outputs the designated image (still image) object 46 on the display 32 '. If it is an image (moving image), the image output unit (moving image) 52 outputs the moving image to the display 32 '. Similarly, if it is text data, the text data output unit 53 outputs the text data of the text object 48 on the display 32 '. In the case of a sound data execution command, the sound output unit 54 outputs sound data of the sound object 47 by the sound output device 33 as sound.

If the processing-specific determination unit 42 determines that there is a plurality of data items to be executed in the designated field, the list display processing unit 43
A list is displayed for a plurality of data managed by the field designated as 2 '. Then, the data type determination unit 44 determines the data type selected on the list display screen. Subsequent processing is the same as when the number of data is one.

In the above processing, the execution button display processing section 45 displays the execution button on the display 32. The instruction execution is instructed by designating the displayed execution button with the cursor. For example, when an execution button is specified in a state where a sound object is specified, the data type determination unit 44 determines that a sound output execution command has been issued. Then, the sound is output by the sound output unit 54. Similarly, when a sound end command is issued by operating the display button, the data type determination unit 44 determines that the command is a sound end command. And the sound output unit 5
4 stops sound output.

S14 Performs processing in accordance with the command (such as reproduction), and returns to S1. S15 It is determined whether the data type is text data. If it is text data, the process proceeds to S16. If it is not text data, the process ends.

S16 Perform processing in accordance with the command (display etc.) and return to S1.

[0077]

According to the present invention, a plurality of types of multimedia data can be handled in one field, so that different types of data can be managed in one field, and the fields can be used effectively.

Further, it is not necessary to perform a process such as activation in accordance with the type of the multimedia data while being aware of the type of the multimedia data. As a result, data management can be performed without being aware of data, making it easier to create an application program and avoiding the complication of command specification when executing the created application program.
