JPH0573377A - Multi-media data interchange processing system - Google Patents

Abstract

PURPOSE:To prevent information from being absent at the time of an interchange of multi-media data. CONSTITUTION:The interchange processing system for multi-media data consists of a means 2 which divides data generated by a program into common data and individual data, a means 5 which interchanges only the common data or both the common data and individual data, and a means 7 which puts the interchanged data together in a target format.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multimedia data exchange processing system.

[0002]

2. Description of the Related Art Since multimedia data in which various media are mixed has a lot of information, there are many parts having different formats and expressions depending on the programs to be handled, and even the same content produces various data. It is represented in the format.

In the case of exchanging data in such various formats, a common format has been set in advance, and the data of a specific format generated by a program is converted into this format before data exchange, or The data represented in various formats was exchanged as it was.

[0004]

Among the above-mentioned conventional multimedia data exchange processing methods, the method of converting to a common format often causes the loss or change of information during conversion, and therefore the same method is used. Even if data is exchanged between programs that handle data formats, there is a drawback in that all information cannot be transmitted.

Further, the method of directly handling data of various formats has a drawback in that data can be exchanged only between programs that handle the same data format, and the original role of exchange with an unspecified partner cannot be fulfilled.

The present invention solves such a problem and effectively exchanges data represented in the same format without impairing data exchange of data represented in various data formats. The purpose is to do.

[0007]

According to the method of the present invention, in a data exchange processing method for multimedia data expressed in the same data format, a dividing means for dividing data generated by a program into common data and individual data. An exchange means for exchanging only common data or both common data and individual data among the data divided by the division means, and the data acquired by the exchange means are combined as input data to another program. And a synthesizing means for

[0008]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, which has a dividing means 2, an exchange means 5 and a combining means 7.

FIG. 2 is a processing flow of data exchange according to this embodiment. When exchanging data, the format and expression of common data are defined in advance so as not to specify the other party, but there is a lot of information that cannot be represented here in the unique data generated by the program.

Therefore, as shown in FIG. 2, the dividing means 2 first extracts only the common part from the unique generation data 101 generated by the program and creates it as the common data 301 (201). The data that remains without being extracted is collectively held as individual data 401 (202).

An identifier for identifying common data or individual data and type information for the individual data are added to each of the divided data (203).

Next, when exchanging data, the exchange source acquires the data name to be exchanged and the type information of the individual data that can be exchanged from the exchange destination (501).

The acquired type information is collated with the type information of the individual data added to the data indicated by the data name, and if they match, the common data and the individual data are
If they do not match, it is determined that only common data will be exchanged (502).

This judgment result is transmitted to the exchange destination (50
3) According to this result, the exchange means 5 exchanges only the common data or both the common data and the individual data (504).

The exchange destination discriminates the transmitted result (70
1), the synthesizing means 7 synthesizes using the post-exchange data 601 obtained by the data exchange (702), and creates the input data 801 of the target program.

[0017]

As described above, according to the present invention, it is possible to exchange necessary and sufficient data with a specific partner without hindering the original purpose of exchanging data with the unspecified partner. There is a point.
