ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a network apparatus which can deal with information such as image information by mobile terminals, process and store the information, and reproduce continuously the information.
In the prior art, in order to reproduce continuously moving picture information of the Internet by a terminal, compressed information is transferred to a memory of the terminal and then transferred information is expanded on the memory of the terminal to reproduce the moving picture there since the Internet does not allow real-time communication. In the event that the moving picture information is transferred piece by piece, the image information is reproduced according to such a method that, when reproduction of the image information is completed up to the transferred image portion, the succeeding image information is received sequentially and then reproduced. Therefore, it has been impossible to achieve continuous reproduction of the image information while the image information is being received.
In addition, the screens of the image information vary in size for each different content. Therefore, the size of the screens of the terminal has been taken into account.
However, in the image information transmission system in the prior art, there has been the problem that the continuous reproduction of the image information cannot be achieved as described above. Furthermore, in order to reproduce the moving picture information for a long time by the mobile terminal, there has been another problem that a high performance CPU and a large capacity memory must be prepared to execute the image processing at a high speed.
SUMMARY OF THE INVENTION
The present invention has been made to overcome the above problems in the prior art, and it is an object of the present invention to provide a network apparatus which is capable of achieving continuous reproduction of the image information by processing the information being supplied from the Internet or the mobile network into the information which is suitable for the mobile terminal, then storing processed information into the storage unit, and then transmitting the image information every unit time to continue the reading timing, without a high performance CPU and a large capacity memory in a mobile terminal.
The present invention can overcome the above problems as described in the following.
1. In order to overcome the above problems, the present invention provides a network apparatus for communicating multi-media information by mobile terminals, comprising an Internet interface means for establishing an interface with the Internet; a mobile interface means for establishing an interface with a mobile network; a protocol processing means for applying a protocol process to information which is processed by the Internet interface means and the mobile interface means; an image information edit processing means for editing image information which is extracted by the protocol processing means into image information suitable for a mobile communication; a storage unit for storing the image information which is edited by the image information edit processing means; and a storage unit controlling means for controlling to store the image information in the storage unit and to read the stored image information.
2. In order to overcome the above problems, in the present invention, the image information which is transmitted/received in respective interfaces of the Internet interface means, the mobile interface means, the protocol processing means, the image information edit processing means, and the storage unit controlling means is communicated in a cellulated format.
3. In order to overcome the above problems, in the present invention, the mobile interface means includes a mobile protocol reception processing means for receiving information from the mobile network and then informing the protocol processing means, a mobile protocol transmission processing means for transmitting information from the protocol processing means and information from the storage unit controlling means to the mobile network via a transmission process, and a transmission timing control processing means for informing the storage unit controlling means of a transmission timing so as to transmit the image information continuously every unit time, whereby continuous reproduction of the image information for the mobile network can be achieved.
4. In order to overcome the above problems, in the present invention, the Internet interface means includes an Internet protocol reception processing means for performing a communication process of the information received from the Internet and then informing the protocol processing means, and an Internet protocol transmission processing means for transmitting the information received from the protocol processing means to the Internet, and also includes an interface for cellulating the information to communicate communication information and the image information when the Internet protocol reception processing means and the Internet protocol transmission processing means communicate with the protocol processing means.
5. In order to overcome the above problems, in the present invention, the protocol processing means includes an Internet protocol address analysis processing means for determining that the information from the Internet interface means corresponds to either communication information or the image information, an image information protocol processing means for executing a protocol process of the image information from the Internet protocol address analysis processing means, a data reproduction processing means for processing the image information which is protocol-processed by the image information protocol processing means to reproduce original information, and a communication network protocol processing means for protocol-processing the information supplied to the Internet and the mobile network. The image information protocol processing means has a communication processing function for executing the communication to transmit/receive the image information to/from the mobile network and a communication processing function for fetching the image information from the Internet. The data reproduction processing means has a function for expanding compressed image information and a function for processing image information of a still picture and a moving picture. The image information protocol processing means has a communication processing function for communicating the image information in the form of a split communication in the communication with the content server in which the image information of the Internet is stored.
6. In order to overcome the above problems, in the present invention, the image information edit processing means includes a reproduced data storage unit for storing the image information reproduced by the protocol processing means, a received data managing means for managing writing/reading of reproduced data into/from the reproduced data storage unit, and a reproduced data editing means for editing the reproduced data read from the reproduced data storage unit into a format which is suitable for the mobile terminal.
7. In order to overcome the above problems, in the present invention, the reproduced data editing means has a function for editing the image information according to type of the mobile terminal which executes the communication via the mobile network, a function for editing a size of the image into a format suitable for the mobile terminal by thinning the information from the reproduced data, and a function for editing the image information into the format suitable for the mobile terminal by converting the color information of the reproduced data into mono-chrome information.
8. In order to overcome the above problems, in the present invention, the storage unit controlling means includes an edit data split processing means for splitting edited information edited by the image information edit processing means into cellulated information to write it into the storage un
