The present invention relates to a network system such as a home network, and more particularly to a network system based on a remote user interface (Remote User Interface, hereinafter referred to as RUI) protocol and a recording medium on which a program .

The RUI protocol is used to move digital media content between an RUI client and a RUI server connected to the same network as a Universal Plug and Play (UPnP) based home network. That is, the RUI client requests RUI (Remote User Interface) information to the RUI server through the RUI protocol and, when RUI information is received from the RUI server, reproduces the received RUI information. In this way, the RUI client provides the RUI service to the user by sharing the RUI information provided by the RUI server.

When the RUI client and the RUI server respectively support the pointing device function, the existing RUI client generates a pointing event every time the user's selection action using the pointing device is performed, To the RUI server. The user's selection action using the pointing device corresponds to a click event of a mouse button when the pointing device is a mouse. Accordingly, the RUI server provides RUI information according to the received pointing location information and the pointing event information to the RUI client. When the RUI client and the RUI server respectively support the function of the pointing device, the RUI client provides the RUI service to the user by sharing the RUI information of the RUI server every time a pointing event is generated.

However, the RUI information of the RUI server supporting the function of the pointing device may include RUI information related to the movement of the pointing device in addition to the pointing event. For example, the RUI information of the RUI server may include RUI information for providing an RUI service such as a roll-over service or a highlight service according to the movement of the pointing device.

However, the RUI client included in the existing RUI protocol-based network system does not generate an event according to the movement of the pointing device. Therefore, when the pointing device is moving in the RUI client, there is no information transmitted from the RUI client to the RUI server. Therefore, even if the RUI server has the RUI information according to the movement of the pointing device, the RUI client can not share the RUI service according to the movement of the pointing device supported by the RUI server.

The present invention provides a RUI protocol-based network system in which an RUI client and an RUI server can share an RUI service according to movement of a pointing device, a method thereof, and a recording medium on which a program for performing the method is recorded have.

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

1 is a functional block diagram of a network system according to an embodiment of the present invention. Referring to FIG. 1, the network system includes a server 100, a network 110, and clients 120.

The server 100 provides a remote user interface (RUI) service for a pointing device movement event generated from at least one client among the clients 120 connected through the network 110.

When at least one client of the server 100 and the client 120 is connected through the network 110, the server 100 generates RUI information and transmits the RUI generated by the client connected to the server 100 And transmits information. RUI information generation in the server 100 may be defined as RUI capture. This is because the RUI information that can be provided to the server 100 is provided in advance and captures and provides the corresponding RUI information from the provided RUI information. The RUI information transmitted from the server 100 to the client connected to the server 100 can be transmitted as an image file using a protocol such as eXternal Beam Radiation Therapy (XRT) or VNC (Virtual Network Computing).

The connection between the server 100 and the clients 120 can be performed by the clients 120 using a URL (Uniform Resource Locator) of the server 100 or a URI (Uniform Resource Identifier). The connection from the clients 120 to the server 100 is a model example of 2 boxes or 3 boxes defined by UPnP or the like and is connected to DLNA (Digital Living Network Alliance) V2, CEA ) Working Group (WG) 7.9.

After the RUI information is transmitted to the client connected to the server 100, when the pointing device movement event and the corresponding position information are received from the client connected to the server 100, the server 100 transmits the received pointing device movement event And RUI information corresponding to the corresponding position information. That is, the server 100 captures the RUI information according to the pointing device movement event and the corresponding location information.

The server 100 transmits the generated RUI information to the client connected to the server 100. At this time, the server 100 can check whether there is an RUI service corresponding to the received pointing device movement event. For example, when the server 100 can provide a rollover service or a highlight service according to the movement of the pointing device, when the received pointing device movement event is a service available from the server 100 It is possible to check whether the event is a pointing device movement event corresponding to the pointing device movement event. If the received pointing device movement event is a pointing device movement event corresponding to the RUI service that can be provided by the server 100, the server 100 generates RUI information corresponding to the received pointing device movement event to connect to the server 100 Lt; / RTI >

When an event other than the pointing device movement event and the corresponding location information are received, the server 100 generates RUI information according to the received event, and transmits the generated RUI information to the client connected to the server 100.

When disconnection is requested from the client connected to the server 100, the server 100 terminates the RUI service function for the client connected to the server 100.

The clients 120 include first through n-th clients 120_1 through 120_n. The first to nth clients 120_1 to 120_n may display RUI information such as a PDA (Personal Digital Assistant), a multifunction printer, a camcorder, a DSC (Digital Still Camera), an MP3 player, ≪ / RTI >

The client connected to the server 100 is at least one of the first to nth clients 120_1 to 120_n included in the clients 120. [ In other words, the client connected to the server 100 may receive all of the first through n-th clients 120_1 through 120_n or some of the first through n-th clients 120_1 through 120_n, 120_1 to 120_n may be applicable.

Accordingly, all of the first to n-th clients 120_1 to 120_n are connected to the server 100 to receive the RUI service for the pointing device movement event and other events provided by the server 100, Some of the clients 120_1 to 120_n are connected to the server 100 to receive the RUI service for the pointing device movement event and the other events provided by the server 100 or the first to nth clients 120_1 to 120_n May be connected to the server 100 to receive the RUI service for the pointing device movement event provided by the server 100 and other events.

The first to n-th clients 120_1 to 120 - n generate a pointing device movement event for a position where the movement of the pointing device stops when each pointing device (not shown) does not move for a predetermined time.

The network 110 is connected to a RUI such as DLNA (Digital Living Network Alliance) V2, CEA (Consumer Electronics Association) WG (Working Group) 7.9 according to a model example of 2 boxes or 3 boxes defined by UPnP The server 100 and the clients 120 are connected to each other in a defined manner to transmit and receive information based on the RUI protocol.

In order to operate as described above, the server 100 may be configured as shown in FIG. 2 is a functional block diagram of the server 100 shown in FIG. Referring to FIG. 2, the server 100 includes a communication unit 201, an RUI information generation unit 202, and a control unit 203.

The communication unit 201 transmits and receives information between at least one of the first through n-th clients 120_1 through 120 - n included in the clients 120 and the server 100. The RUI information generation unit 202 generates RUI information for a pointing device movement event. However, the RUI information generation unit 202 may be configured to further generate RUI information of an event other than the above-described pointing device movement event.

When the client 100 connected to the server 100 accesses the server 100 via the network 110, the control unit 203 transmits the RUI information to the client connected to the server 100 through the communication unit 201. The control unit 203 controls the RUI information generating unit 202 to receive the pointing device movement event and the corresponding position information from the client connected to the server 100 via the communication unit 201. Then, And generates RUI information according to the movement event. The control unit 203 transmits the generated RUI information to the client connected to the server 100 through the communication unit 201. [

Also, when an event other than the pointing device movement event and corresponding position information are received, the control unit 203 controls the RUI information generation unit 202 to generate remote user interface information according to the received event. The control unit (203) transmits the generated remote user interface information to the client connected to the server (100).

Meanwhile, a client connected to the server 100 may be configured as shown in FIG. Therefore, the first through n clients 120_1 through 120_n shown in FIG. 1 may be configured as shown in FIG. 3 is an example of a functional block diagram of the first to n-th clients shown in Fig. 3, a client connected to the server 100 includes a pointing device 301, a pointing device handler 302, a control unit 303, a communication unit 304, and a screen playback unit 305 .

The pointing device 301 is a device such as a mouse that can input commands.

The pointing device handler 302 monitors the operation of the pointing device 301 and provides the monitoring result to the control unit 303. [ In particular, the pointing device handler 302 monitors the operation of the pointing device 301 and, when the pointing device 301 stops moving for a predetermined time, generates a pointing device movement event to the control unit 303 do. However, the pointing device handler 302 may monitor the operation of the pointing device 301 and generate a pointing event to the control unit 302. [ The pointing event may be generated according to the user's selecting action using the pointing device 301. [

When the pointing device movement event is generated from the pointing device handler 302, the control unit 303 transmits the generated pointing device movement event and the corresponding position information to the server 100 through the communication unit 304. [ At this time, the transmitted data may have a format as shown in FIG.

4 is a diagram illustrating an example of the format of data transmitted from a client connected to the server 100 to the server 100. As shown in FIG. 4 is an exemplary diagram of a data format when a client connected to the server 100 and the server 100 transmit data in a TCP-based packet transmission scheme. This can be known based on the information defined in the fields (400) and (410).

In addition, FIG. 4 includes a 2-byte command length 421, 2-byte command identification information, and 4-byte data in the data field. The command ID may include a pointing device down (pointing device-down or mouse-down or key-down), a pointing device up (pointing device-up or mouse-up or key-up), and a pointing device movement -move or key-move) can be defined. The pointing device movement is an instruction indicating that the pointing device movement event has been generated as the pointing device 301 stops moving for a predetermined time. The pointing device down and pointing device up are instructions used to enable continuous input values to be distinguished from the server 100. [ The data includes the x coordinate (or the x position of the image) of the position where the movement stopped, the y coordinate (the y position of the image) of the position where the movement stopped, and the right button of the pointing device And button mask information indicating whether the left button is controlled may be defined.

The pointing device movement event is generated in a state in which the RUI screen is reproduced by the screen reproduction unit 305. [ Thereafter, when the RUI information is received from the server 100, the control unit 303 controls the screen reproduction unit 305 to reproduce the RUI screen according to the received RUI information. Accordingly, the RUI screen reproduced by the screen reproduction unit 305 is updated.

The communication unit 304 transmits and receives information between the server 100 and clients connected to the server 100. The screen reproduction unit 305 is controlled by the control unit 303 to reproduce the RUI screen.

A client connected to the server 100 can be configured as shown in FIG. Accordingly, the first through n clients 120_1 through 120_n shown in FIG. 1 may be configured as shown in FIG. 5 is another example of a functional block diagram of the first to n-th clients shown in Fig. 5, a client connected to the server 100 includes a pointing device 501, a pointing device handler 502, a timer 503, a control unit 504, a communication unit 505, (506).

The pointing device 501, the control unit 504, the communication unit 505 and the screen reproduction unit 506 are similar to the pointing device 301, the control unit 303, the communication unit 304, 305).

The pointing handler 502 monitors the operation of the pointing device 501. As a result of the monitoring, when the pointing device 501 stops moving, the timer 503 is driven at the point of time when the movement stops.

The timer 503 starts measuring time from the point in time when it is driven by the pointing device handler 502. [ The pointing device handler 502 monitors whether or not the pointing device 501 is moving and the time measured in the timer 503. If it is determined that the predetermined time has passed after the pointing device 501 stops moving, the control unit 504 generates a pointing device movement event. When the pointing device movement event is generated, the time measured in the timer 503 is cleared by the pointing device handler 502. [ The predetermined time is set in advance. For example, 0.5 seconds may be set to a predetermined time.

6 is a flowchart illustrating a method of operating a server in a method according to another embodiment of the present invention. The operation of FIG. 6 will be described with reference to FIG. 6, it is assumed that the client connected to the server 100 is the first client 120_1 of the clients 120. In this case, However, the client connected to the server 100 is at least one client among the first through n-th clients 120_1 through 120_n as described with reference to FIG. 1, and is at least one client among the clients included in the network system.

When a pointing device movement event is received from the first client 120_1, the server 100 generates RUI information according to the received pointing device movement event and the corresponding position information (601, 602). At this time, RUI information generation can be expressed by RUI information capture. When the RUI information is generated, the server 100 transmits the generated RUI information to the first client 120_1 (603). The generated RUI information may be defined as updated RUI information.

A method of operating the first client 120_1 with respect to the operation method of the server 100 is as shown in FIG. 7 is a flowchart illustrating an operation method of a client in a method according to another embodiment of the present invention.

As shown in FIG. 7, the client connected to the server 100 is assumed to be the first client 120_1, and the operation flowchart of FIG. 7 will be described with reference to FIG.

When the first client 120_1 generates a pointing device movement event, the generated pointing device movement event and the corresponding position information are transmitted to the server 100 (701, 702).

Next, when the RUI information according to the pointing device movement event is received from the server 100, the first client 120_1 reproduces the RUI information based on the received RUI information (703, 704). The RUI information reproduction in step 704 can be defined as RUI information update. This is because the pointing device movement event occurrence in step 701 can occur in a state where the RUI information is being reproduced.

FIG. 8 is a flowchart illustrating an operation method of a server in a method according to another embodiment of the present invention.

8, when the pointing device movement event is received from the first client 120_1, it is assumed that the server 100 receives the pointing device movement event among the RUI services that it can provide And checks whether there is a corresponding RUI service (801, 802). For example, when the server 100 is able to provide a rollover or highlight service according to a moving event of a pointing device, the received pointing device movement event is notified to the pointing device movement event that should provide the rollover or highlight service You can check if it is applicable.

If it is determined that the RUI service corresponding to the received pointing device movement event exists in the server 100, the server 100 generates RUI information according to the pointing device movement event and transmits the generated RUI information to the first client 120_1 (803, 804). On the other hand, if it is determined in operation 802 that the RUI service corresponding to the received pointing device movement event does not exist in the server 100, the server 100 performs RUI information generation and transmission operations according to the pointing device movement event And terminates the operation for the received pointing device movement event.

Unless RUI information generation and transmission is performed as described above, no information is transmitted from the server 100 to the first client 120_1. Therefore, even if a pointing device movement event is generated, the first client 120_1 does not update the RUI screen reproduced accordingly. At this time, the server 100 may notify that there is no RUI service for the corresponding pointing device movement event.

When the operation of the server 100 is performed as shown in FIG. 8, in operation of FIG. 7 of the first client 120_1, operation 703 may be modified to end the operation if the RUI information is not received.

Figure 9 is a flow chart of a client's operation in a method according to another embodiment of the present invention. 6, the first client 120_1 and the server 100 are connected to each other. For example, the operation of FIG. 9 will be described as follows.

The first client 120_1 accesses the server 100 in the same manner as described with reference to FIG. 1 (901). The server 100 may be defined as an RUI server.

After the first client 120_1 and the server 100 are connected, when the RUI information is received from the server 100, the first client 120_1 checks whether the pointing device of the first client 120_1 has stopped moving (902, 903).

If it is determined that the pointing device has stopped moving, the server 100 checks whether a predetermined time has passed after the pointing device stops moving (904). If it is determined that the predetermined time has passed after the pointing device stops moving, the first client 120_1 generates a pointing device movement event (905).

Next, the generated pointing device movement event and corresponding position information are transmitted to the server 100 (906). Thereafter, when the RUI information is received from the server 100, the first client 120_1 reproduces the RUI screen according to the received RUI information (908). Accordingly, the RUI screen reproduced by the first client 120_1 is updated.

10 is a flowchart illustrating the operation of the server 100 in the method according to another embodiment of the present invention, when the first client 120_1 is operated as shown in FIG. 9 .

The first client 120_1 and the server 100 are connected to each other via the network 110 in the same manner as described with reference to FIG. 1 (1001). The first client can be defined as an RUI client.

When the first client 120_1 and the server 100 are connected, the server 100 generates RUI information (1002). The generated RUI information is transmitted to the first client 120_1 (1003). Then, when a pointing device movement event is received from the first client 120_1, the server 100 checks whether there is an RUI service corresponding to the currently received pointing device movement event among the RUI services that the server 100 can provide (step 1005) .

If it is determined that there is an RUI service corresponding to the currently received pointing device movement event, the server 100 generates RUI information according to the pointing device movement event (1006). Then, the server 100 transmits the generated RUI information to the first client 120_1 (1007). Accordingly, the first client 120_1 updates the RUI screen reproduced as described with reference to FIG. 9 according to the received RUI information.

In a network system having at least one client and a server according to the present invention, a program for executing a server operating method and a client operating method for a remote user interface service may be embodied as computer readable code on a computer readable recording medium It is possible to do. A computer-readable recording medium includes all kinds of storage devices in which data that can be read by a computer system is stored. Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may be implemented in the form of a carrier wave (for example, transmission via the Internet) . The computer readable recording medium may also be distributed over a networked computer system and stored and executed as computer readable code in a distributed manner.

The present invention has been described with reference to the preferred embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense.

As described above, according to the present invention, in an RUI (Remote User Interface) protocol-based network, an RUI client shares a RUI service supported by an RUI server with respect to a pointing event as well as a pointing event, The scope of the RUI service can be expanded.

For example, an RUI client can share an advanced RUI service for a pointing device such as a rollover service or a highlight service according to movement of a pointing device supported by the RUI server.

In addition, the present invention can prevent the network from being wasted due to the occurrence of an unnecessary pointing device movement event, by causing the RUI client to generate the pointing device movement event at the coordinates at which the movement of the pointing device is stopped for a predetermined period of time.
