As a result of the determination, if only the specific data is needed by the receiving device, only the required data is transmitted from the transmitting device to the receiving device (S2550), and when the determination result is not only the specific data, the data transmission mode is supported. All the data to be transmitted is transmitted from the transmitting device to the receiving device (S2560).

For example, if a document file having the same name is stored in the sending device and the receiving device, and some data such as underscores, bookmarks, and specific marks are added to the document file stored in the sending device, the receiving device uses the same pre-stored name. Without having to receive the entire document file, only partial data added such as the underline, bookmark, and specific mark is received. Accordingly, when data is transmitted from the set transmitting device to the receiving device, data stored in the multi-screen device and the external device are analyzed, and data related to the transmitted data is extracted, and only the extracted data is transmitted.

In the case of using the above process, in transmitting data, it is possible to increase device efficiency in terms of time, power consumption, and memory usage because only the necessary data can be transmitted, such as the added part, without transmitting duplicate data. There is a technical effect.

Further, for convenience of description, each drawing is divided and described, but it is also possible to design to implement a new embodiment by merging the embodiments described in each drawing. And the multi-screen device and the control method according to an embodiment are not limited to the configuration and method of the embodiments described as described above. That is, the above-described embodiments may be configured by selectively combining all or part of each embodiment so that various modifications can be made.

In addition, although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and the technical field to which the present invention pertains without departing from the gist of the present invention claimed in the claims. In addition, various modifications can be implemented by a person having ordinary knowledge in the course, and these modifications should not be individually understood from the technical idea or prospect of the present invention.

In addition, in the specification, both the object invention and the method invention are described, and the description of both inventions may be applied supplementally as necessary.
