The present invention relates to a remote screen control method, and more particularly, by providing a screen on a server or a separate control screen inside a server to a client so that a screen suitable for a client's own performance can be obtained even if there is no control program for controlling a specific application. The present invention relates to a remote screen control method for remotely controlling a control target of a server in an optimal screen state by selecting and transmitting the same from a server.

Conventionally, a method of controlling a remote screen includes a desktop remote sharing provided by Microsoft, a Virtual Network Computing (VNC) protocol, and the like.

Here, the VNC protocol scheme operates using the VNC protocol between the VNC server and the remote VNC client. In other words, if a server program (daemon) called a VNC server is placed on a server to be remotely controlled and monitored, the server is managed using a client program called 'VNC Viewer' anywhere a TCP / IP environment is supported.

In addition, the VNC protocol is based on the concept of Remote Frame Buffer (RFB), which refers to a space for temporarily storing data to be displayed on a screen in a general GUI system. Therefore, when the contents of the frame buffer of the local system are updated, the VNC server delivers the changed contents to the frame buffer of the client computer using the VNC protocol, and the VNC viewer displays the contents on the screen of the client computer.

By the way, while the conventional remote screen control method is simple to implement the client, the client has to bring the data as inefficient frame information and display it on the screen, there is a problem that the performance burden occurs. In other words, the frame information transfer method requires more than a certain level of performance from the client, but the low-performance client such as an embedded system with a low-performance CPU cannot perform image decoding quickly, resulting in a slow screen display and even basic control. It is difficult to put a significant burden on the system, there is a problem that the delay time beyond the limit occurs in the actual control. Therefore, there is an urgent need for a remote screen control method for each level that enables a smooth display operation even in a client having low CPU performance.

In order to solve the above problems, the present invention provides a screen on the server or a separate control screen inside the server to the client, even if there is no control program for controlling a specific application in the client to select the screen suitable for the performance of the client itself and transmit from the server. It is an object of the present invention to provide a remote screen control method for remotely controlling the control target of the server by receiving and installing.

According to an aspect of the present invention, there is provided a remote screen control method, comprising: a first step of a client accessing a server having a plurality of level-specific screen data; A second step of transmitting performance information from the client to the server; And a third step of transmitting screen data suitable for the level of the performance information to the client.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings.

In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

1 is a configuration diagram schematically showing a configuration of a home network apparatus to which a remote screen control method according to an exemplary embodiment of the present invention is applied.

The home network apparatus 100 to which the present invention is applied possesses various levels of screen data according to the performance of each client, provides a remote screen for basic control to the connected client 120, and then receives the performance from the client 120. The server 110 transmits the screen data suitable for the performance of the client 120 to the client 120 based on the information, and transmits its performance information to the server 110, and then receives it from the server 110. It has a configuration including a client 120 for installing one screen data in the system.

In this case, the level of screen data held by the server 110 includes a level for transmitting the screen frame to be transmitted as it is, a part for complicated or decorative screen frame, a level for omitting and transmitting other animations, and a part necessary for control. Only partially transmits the screen frame of, passes only the simple text specially designed for low-performance clients omitting the original screen frame, and only the corresponding position information and shape information for menu output, and pure text ( Text) and the level to deliver only the output location information.

2 is a flowchart illustrating a remote screen control method according to an embodiment of the present invention.

First, the server 120 holds the remote screen information for each client level in a storage means such as a memory or a database (S202).

On the other hand, the client 110 is connected to the server 120 through the TCP / IP communication (S204).

When the client 110 connects to the server 120, the server 120 transmits the remote screen for basic control to the connected client 110, and performance information including statistical information such as time required for image decoding or data transmission. It is required (S206).

The client 110 transmits performance information including statistical information about image decoding, data transmission time, etc. to the server 120 to which the client 110 is connected (S208).

The server 120 analyzes the performance information including the statistical information to determine the level of the client, such as whether the current transmission level needs to be changed (S210). That is, the server 120 uses the performance information received from the client 110 to determine whether the current screen transmission level is a burden to control the client 110, if the current transmission level is the performance level of the client If it is determined to be over, it lowers the transmission level to an appropriate level, and conversely, if the current transmission level is assigned lower than the performance level of the client, it is raised to an appropriate level.

The server 120 transmits screen data suitable for the performance level of the client to the client 110 (S212). Here, the level of screen data transmits the screen frame to be transmitted as it is, a part of the complicated or decorative screen frame, the level of omitting and transmitting other animations, and only partially transmitting the screen frame necessary for control. Level, the level that delivers only text and corresponding location information and shape information for menu output that are separately created for low performance clients, omitting the original screen frame, and pure text and corresponding output location information Level of delivery. This can enable the desired level of control in the client if accurate text-based information can be delivered without compromising the quality of the screen. In addition, by simply transforming complex menu images into simple figure information and the like, a low-level image decoding client can serve a desired level of menu interface.

Accordingly, the client 110 may install the screen data suitable for the received performance level of the client 110, and perform the necessary control on the server 120 in an optimal screen state.

As described above, according to the present invention, by providing a screen on the server or a separate control screen inside the server to the client, even if there is no control program for controlling a specific application in the client, the screen is selected according to the performance of the client itself and received from the server It is possible to realize a remote screen control method that allows the remote control of the control target of the server.
