Problems solved by technology

Therefore, it is impossible to achieve continuous reproduction of image information while the image information is being received
[0003] In addition, the size of the image information screen is different for each content, regardless of the screen size of the terminal
[0004] However, in the prior art image information transmission system, there is a problem that, as described above, continuous reproduction of image information cannot be realized.
Moreover, in order to reproduce moving picture information for a long time with a mobile terminal, there is another problem that it is necessary to provide a high-performance CPU and a large-capacity memory to perform image processing at a high speed.

Abstract

A network apparatus which enables continuous reproduction of image information without a necessity of a high performance CPU and a large capacity memory in mobile terminals, comprises: an Internet interface means 5 for establishing an interface with the Internet 1, a mobile interface means 7 for establishing an interface with a mobile network 4, a protocol processing means 6 for applying a protocol process to information which are processed by the Internet interface means and the mobile interface means, an image information edit processing means 8 for editing image information which are extracted by the protocol processing means into image information suitable for a mobile communication, a storage unit 10 for storing the image information which are edited by the image information edit processing means, and a storage unit controlling means 9 for controlling to store / read the image information into / from the storage unit.

Description

technical field [0001] The present invention relates to a network device capable of processing information such as image information with a mobile terminal, processing and storing the information, and continuously reproducing the information. Background technique [0002] In the prior art, since the Internet cannot realize real-time communication, in order to continuously reproduce the moving picture information of the Internet with the terminal, the compressed information is transmitted to the memory of the terminal, and then the transmitted information is expanded in the memory of the terminal , to reproduce the live frame there. If the moving picture information is transmitted in parts, the image information is reproduced in such a way that when the reproduction of the image information completes the transmitted image portion, subsequent image information is sequentially received and then reproduced. Therefore, it is impossible to achieve continuous reproduction of image...
