  On the other hand, in order to facilitate the description of the present invention, a basic concept related to the present invention is defined.

  'Service' is multimedia content expressed in one bundle, and many service components form one service.

  'Service component' is a part constituting a service, and includes a video component, an audio component, and a data component. At this time, the data component indicates an application existing in the service.

  In addition, the application is classified into an unbound application and a service bound application. However, since the unbound application is not related to a specific channel, the execution of the application is not affected by the channel change. Moreover, since it generally has a high priority, resources for execution are smoothly allocated. The monitor application corresponds to a special unbound application that may have the highest priority.

  On the other hand, the service bound application is related to the transmission stream, and generally has a lower priority than the unbound application. Service bound applications cannot perform decisive system functions, and have greater chances of giving up resource allocation than unbound applications when competition for resources occurs. There are two types of service bound applications: a linked type that operates in conjunction with a stream that is currently being transmitted, and a non-linked type that operates regardless of the stream that is being transmitted.

  'Service context' includes various resources, devices, and execution state information related to service execution, and represents an object that can control service execution.

  The 'display screen' means a physical device in which the service content is actually expressed, an external output port from which the service content is output, or a storage device in which the service is stored.

  An 'output screen' is a screen that is actually output to the display screen, and any service set directly on the output screen and expressed through the display screen, or mapped to a certain area of the output screen One or more logical screens are output through the display screen.

  The 'logical screen' is a space in which an arbitrary service is expressed, and before being mapped to the output screen, it exists only virtually on the memory and is not actually displayed on the display screen.

  In addition, the logical screen and the output screen are composed of a combination of a background still image, a video raster, and a graphic raster, where the graphic raster is a combination of text, lines, colors, and images, or A mix of video frames is provided.

  'Main service' means a service selected by a user as a main service through a menu or a remote control that appears on a display screen, or through an API, and a screen on which the main service is expressed is referred to as a 'main screen'.

  'PiP service' means a service that the user selects through the menu or remote control that appears on the display screen, or an application selected as a secondary service in the main screen through the API. Expressed.

  As shown in FIGS. 1A to 1D, a “PiP screen” is a screen that occupies a partial area in another screen, and an area that does not overlap with another screen as shown in FIGS. 1E and 1F. And a screen that can be seen at any position and area within the display screen or superimposed on other screens, as shown in FIGS. 1G and 1H. It is understood as a concept comprising

  FIG. 2 is an exemplary diagram illustrating a relationship between a logical screen and an output screen according to an embodiment of the present invention. Referring to FIG. 2, a service is expressed through logical screens 210, 212, and 214, and the logical screen is mapped and expressed on output screens 220, 222, and 224 by a predetermined mapping block 230.

  At this time, the output screen referenced by 220 is represented by mapping the logical screens referenced by 210 and 212, and the output screen referenced by 222 is mapped by the logical screens referenced by 212 and 214. The output screen referenced by 224 is represented by mapping the logical screens referenced by 210, 212, and 214.

  In this way, at least one or more logical screens on which the service is represented are mapped to any area of the output screen by the mapping block 230.

  Meanwhile, the mapping block 230 is understood as a collection of various information for mapping a logical screen and an output screen. Examples of such information include coordinate information of the area where the logical screen is mapped to the output screen, identification information that distinguishes the logical screen from the output screen, and information about the order in which multiple logical screens are represented on the output screen. sell.

  The mapping block 230 may resize the logical screen and assign it to a certain area of the output screen. That is, the mapping block 230 can perform a scaling function and a position assignment function for a logical screen. FIGS. 3A to 3E show a configuration of such a mapping block, that is, a screen including a mapper.

  Referring to FIG. 3A, the main screen composed of the combination of the background still image B, the video raster V, and the graphic raster G is mapped by the mapper over the entire output screen while maintaining the size. The PiP screen having only the video component is mapped to a certain area of the output screen by the mapper while the size is reduced. At this time, the mapped PiP screen is placed on the main screen, which is determined by the Z value. Z represents a z-order value, and z-order will be described later. An overlay screen is combined with the output screen. The overlay screen is a special screen placed on the outermost side, and is used when, for example, subtitles need to be provided. The PiP screen can have only a video component as shown in FIG. 3A, but can also consist of a combination of background still image B, video raster V, and graphic raster G as shown in FIG. 3B. .

  Referring to FIG. 3C, the main screen composed of the combination of the background still image B, the video raster V, and the graphic raster G is mapped to the entire output screen by the mapper while maintaining the size. Then, the two PiP screens # 1 and # 2 having only the video component are mapped to a certain area of the output screen by the mapper while the size is reduced. At this time, the mapped PiP screen is placed on the main screen, and at this time, the Z value is kept the same. An overlay screen is combined with the output screen. The screen configuration may comprise a plurality of PiP screens having only video components as shown in FIG. 3C, but a combination of background still image B, video raster V and graphic raster G as shown in FIG. 3D. It may be composed of a plurality of PiP screens.

  In FIG. 3E, a POP (Picture-Outside-Picture) screen is shown. However, if the PiP screen is a screen that is represented inside the main screen, the POP screen in the related art is represented outside the main screen. It is understood as a screen. Referring to FIG. 3E, a plurality of POP screens # 1 and # 2 composed of a combination of the background still image B, the video raster V, and the graphic raster G are reduced in size by the mapper, Maps to a certain area. At this time, the Z values of the mapped POP screens # 1 and # 2 are kept the same. An overlay screen is combined with the output screen and expressed.

  The mapping block 230 is implemented by an interface and a function created and executed in various computer program languages, and can generate or change the relationship between the logical screen and the output screen using the information as a parameter. .

  The mapping block 230 may be implemented as hardware so as to perform a mapping function between the logical screen and the output screen.

  On the output screen, services provided from various sources are expressed and output through the display screen, which is shown in FIG.

  Generally, there are sources that provide broadcasting services such as terrestrial broadcasting 320 and cable broadcasting 330 as sources that provide services, and are stored in a predetermined recording medium such as a PVR (personal video recorder) 340. Some sources provide services. In addition, although not shown in FIG. 4, sources that provide services through a wired or wireless network are also included here.

  At this time, the broadcast receiving apparatus 310 receives services from such a source, and generates a logical screen representing each service.

  Then, according to a preset scheme, a scheme set by a user or an application, any service is set directly on the output screen and expressed through the display screen 350, or is mapped to a certain area of the output screen. One or more logical screens are output through the display screen 350. FIG. 4 shows that services provided by the terrestrial broadcast 320, the cable broadcast 330, and the PVR 340 are expressed through the display screen 350.

  In FIG. 4, terrestrial broadcasting 320, cable broadcasting 330, and PVR 340 are shown as examples of sources that provide services. However, sources that provide services are not limited to this, and are represented by a single bundle. If multimedia content is provided, it is included in the source of the present invention.

  On the other hand, services in the present invention include abstract services and non-abstract services, which are shown in FIGS. 5A and 5B, respectively.

  An abstract service is a service that is not a service that is transmitted in real time from a broadcast signal and that is independent of a broadcast channel. Can correspond to an abstract service. For example, a service comprising an unbound application in the OCAP (Open Cable Application Platform) standard belongs here.

  A non-abstract service is understood as the rest of the service excluding the abstract service.

  In the present invention, independence can be given to each of the abstract service and the non-abstract service. For example, an abstract service is set directly on an output screen without going through a logical screen, and a non-abstract service is mapped to an output screen that is expressed on the logical screen and set with an abstract service. Then, the output screen is output through the display screen, whereby the abstract service and the non-abstract service are independently expressed on one output screen. In addition, after both abstract service and non-abstract service are mapped to separate logical screens, each logical screen may be mapped to one output screen. That is, the abstract service and the non-abstract service are expressed on the output screen as independent forms.

  On the other hand, the logical screen and the output screen in the present invention are defined as separate objects, but the 'screen' functions as a logical screen or is output depending on the attribute information of one object called 'screen'. It can also function as a screen.

  That is, it can be known whether the screen is a logical screen or an output screen through the type information among the attribute information regarding the screen object.

  As such screen object attribute information, there are 'Type', 'z-order', 'Display_Area', 'Visibility', 'Associated_Display_Screen', 'Associated_Service_Contexts', and 'Output' information.

  FIG. 6 shows types of screen object attribute information and an interface for processing such attribute information.

  The 'Type' attribute 510 is attribute information indicating whether the screen is a logical screen or an output screen.

  The 'z-order' attribute 520 is for determining the order on the z-axis when the logical screen is represented on the output screen, and in FIG. It illustrates how it can be seen by the order attribute.

  In FIG. 7, on the output screen 610, a first logical screen 620 and a second logical screen 630 are mapped and expressed in a certain area. At this time, the first logic screen 620 is represented on the output screen, and the second logic screen 630 is represented thereon. That is, the output screen 610, the first logical screen 620, and the second logical screen 630 are expressed in the z-axis direction. In such a case, the z-order attribute value of the first logical screen 620 is set to 1. And the z-order attribute value of the second logical screen 620 is set to 2. At this time, the z-order attribute value can be any number or character form as long as it is information indicating the order in which the logical screens are expressed on the z-axis of the output screen.

  The 'Display_Area' attribute 530 means information about the area of the output screen that is output by mapping the logical screen to the output screen, which is illustrated in FIGS. 8A and 8B.

  FIG. 8A shows that the logical screen 710 is mapped to the entire area of the output screen 720 and output, and FIG. 8B shows that the logical screen 730 is mapped to a partial area of the output screen 740 and output. Is shown.

  At this time, the information indicating the “Display_Area” attribute 530 is two-dimensional coordinate information on the output screen, or is expressed by a specific position on the output screen and an offset value from the specific position.

  The 'Visibility' attribute 540 is an attribute that determines whether or not a logical screen is seen on the output screen, and by changing this attribute value, the logical screen can be seen or disappear on the physical display screen. You can

  The 'Associated_Display_Screen' attribute 550 represents identification information of an output screen connected to the corresponding logical screen. Logical screens that are not connected to an output screen are not seen on the display screen or transmitted to other external outputs.

  The 'Associated_Service_Contexts' attribute 560 represents information about the service context connected to the logical screen or the output screen itself, but the service set in the service context is represented on the logical screen or the output screen.

  The 'OutputPort' attribute 570 represents information about a target on which the output screen is output, and can include a display screen, a wired / wireless communication medium, and various recording media as targets on which the output screen is output.

  On the other hand, an interface for obtaining or changing a value for the attribute information shown in FIG. 6 is provided, in which the value of the attribute information is set as shown in FIG. 'Set' interface to connect the logical screen with the output screen, add attribute information value, or 'add' interface to connect the logical screen with service, 'get' to get the attribute information value There is a 'remove' interface for deleting the value of the interface and attribute information. Such an interface is understood as a process, a function, a presever, and a method that perform the respective functions.

  For example, the 'getDisplayScreen (void)' method performs the function of returning the output screen associated with the current screen. For example, if the current screen is a logical screen, the associated output screen is returned; if the current screen is an output screen, reference information about the current screen is returned and the current screen is a logical screen. However, if there is no associated output screen, 'NULL' is returned.

  As yet another example, the 'public void setDisplayArea (HSScreenRectangle) throwSecurityException, IllegalStateException' method provides the ability to map the current logical screen to a predetermined area of the associated output screen. The instance provided for the parameter is the 'HSScreenRectangle' class type of the 'org havi.ui' package and has two-dimensional position information. Then, as exception processing for the ‘setOutputScreen (HSScreenscreen)’ method, a ‘SecurityException’ exception and an ‘IllegalStateException’ exception are performed. The 'IllegalStateException' exception is raised if the current screen is not a logical screen or if the area of the output screen associated with the current logical screen is not changed due to the nature of the hardware or software platform.

  As yet another example, the 'getOutputArea (void)' method returns information about the current screen area in the form of an 'HSScreenRectangle' class. If the current screen is the output screen, return the 'HSScreenRectangle' information with the same value as 'HSScreenRectangle (0,0,1,1)', and if the current screen is a logical screen , Information about the area occupied by the logical screen is returned in the associated output screen. Then, if the current screen is a logical screen but there is no associated output screen, a 'NULL' value is returned.

  Each of the interface names described above is merely a name for representing each function, and is not limited to the name, and must be understood as the function.

  FIG. 9 is an exemplary diagram illustrating a process in which two services are set on two logical screens, mapped to one output screen, and output. Referring to FIG. 9, the first service is a service in which all three service components of video / audio / data exist, and the second service is given as an example in which only the video component and the audio component exist. It is a thing. Of course, in the present invention, there are no restrictions on the service component, and FIG. 9 shows one possible example.

  As shown in FIG. 9, the first service and the second service appear on the display screen in a form similar to the conventional method. However, according to the present invention, a plurality of services can be displayed on the display screen through mapping without any number limitation. Can be expressed independently at various positions.

  FIG. 10 is a block diagram illustrating a configuration of a multi-screen providing apparatus according to an embodiment of the present invention. Referring to FIG. 10, the multi-screen providing apparatus 900 according to the present invention includes a digital signal processing module 940, an operation module 970, a user / application interface module 950, and a setting module 960.

  At this time, the term 'module' used in the present embodiment means software or a hardware component such as FPGA (Field Programmable Gate Array) or ASIC (Application Specific Integrated Circuit), and the module plays a role. Do. However, the module is not limited to software or hardware. A module may be configured to reside on a recording medium to be addressed or configured to cause one or more processors to play. Thus, by way of example, a module can be a software component, an object-oriented software component, a component such as a class component and a task component, a process, a function, an attribute, a pre-sector, a subroutine, a segment of program code, a driver, firmware, Includes microcode, circuits, data, databases, data structures, tables, arrays, and variables. The functionality provided in the components and modules may be combined into fewer components and modules or further separated into additional components and modules. In addition, the components and modules may be implemented to play one or more CPUs in a device or secure multimedia card.

  The digital signal processing module 940 receives various pieces of configuration information such as video information, audio information, or data information constituting a service such as multimedia contents from the broadcast signal receiving module 910, the recording medium 920a, or the external input module 930. .

  At this time, the broadcast signal receiving module 910 is a module that receives and transmits a satellite, terrestrial wave, or cable broadcast signal, and the recording medium 920a is a device in which video information, audio information, or data information constituting the service is stored. The external input module 930 is understood as a module that receives and transmits video information, audio information, or data information constituting a service from other devices connected to the network, such as a network interface module.

  The digital signal processing module 940 restores a service using the received service component, and may restore a plurality of services at this time. At this time, the restored service includes an abstract service or a non-abstract service.

  Here, “a plurality of services” may mean, for example, two or more services transmitted by the broadcast signal receiving module 910 and transmitted from each of the broadcast signal receiving module 910 and the recording medium 920a. It can also mean two or more services.

  Services restored in the digital signal processing module 940 may be restored by user selection through the user / application interface module 950. At this time, the user can select the main service and the PiP service.

  The operation module 970 operates the service restored by the digital signal processing module 940 on the logical screen, and then maps the logical screen to the output screen or operates the service directly through the output screen. For this purpose, the operation module 970 includes a service processing module 972 and an output module 974.

  The service processing module 972 generates one or more logical screens and output screens for representing the service restored by the digital signal processing module 940.

  The output module 974 maps and outputs a number of logical screens generated by the service processing module 972 to a predetermined area on the output screen. At this time, the mapping on the output screen has been set or set by the user or application through the user / application interface module 950.

  In addition, the service processing module 972 can generate multiple output screens. In such a case, only the output screen selected through the user / application interface module 950 is provided through the output module 974.

  Further, the service restored by the digital signal processing module 940 is not connected to the logical screen by the service processing module 972, but directly connected to the output screen and output by the output module 972.

  The output screen is output by the output module 974 through the physical display screen 980 or stored in the recording medium 920b. Here, the recording medium 920b is readable by a computer, and includes a floppy (registered trademark) disk, a hard disk, a CD-ROM (read only memory), a DVD, a DVD-ROM, a BD (Blue-ray Disc), and a semiconductor memory. Including.

  In addition, the information may be transmitted to other devices connected to the network through the external output module 990.

  To this end, the output module 974 may comprise a number of output ports to which an output screen is provided, but in such a case, either through a preconfigured basic output port or an output port specified through the user / application interface module 950. An output screen is provided.

  The setting module 960 plays a role of setting screen forms and connection relationships existing in the system. Here, it is understood that the setting reconfigures the form and connection relationship of the generated and output screen. However, for such a setting, the setting module 960 may detect a setting change of the screen.

  Here, the screen includes a logical screen on which the service is represented and an output screen to which the logical screen is mapped, and a setting change is a change of a basic screen on which an application is executed, a change of a service context connected to the screen, and an output. At least one of a change in the screen, a change in the coordinates of the area of the output screen to which the logical screen is mapped, a change in the video port of the screen, a change in the visual attributes of the screen, and a change in the order in which the logical screen is represented including.

  For setting of the setting module 960, the coordinate or size of the screen is changed (hereinafter referred to as the first setting), and the order in which the logical screen is expressed on the output screen, that is, the change of the z-order (hereinafter referred to as the second setting). ), Changing the screen layout method (hereinafter referred to as the third setting) and restricting the execution of the application on the screen (hereinafter referred to as the fourth setting).

  In performing the first setting, the setting module 960 may change the coordinates of the area to which the logical screen is mapped in the area of the output screen and the size of the logical screen.

  In performing the third setting, the setting module 960 may be arranged according to one of at least one arrangement method in which the logical screen is arranged on the output screen.

  Here, the arrangement method includes a first arrangement method in which the service is expressed on the output screen, a second arrangement method in which the output screen of the first arrangement method coexists with at least one overlapping screen, and a screen in which the service is expressed. Corresponds to the logical screen mapped to the entire area of the output screen, corresponds to at least one non-superimposed logical screen mapped to the output screen, and does not correspond to the superimposed screen in the third arrangement method and the third arrangement method A fourth arrangement method in which the screen coexists with at least one superimposed screen, and the screen on which the service is represented corresponds to a combination of at least two non-superimposed logical screens mapped to the entire area of the output screen.

Accordingly, an apparatus that executes a service such as multimedia content receives the above information and restores the corresponding service (S1010). At this time, the service to be restored is selected or preset by the user or application. The user can use a menu or remote control that appears on the display screen, or the application can select which service to connect to which screen using the API.

  On the other hand, the data information includes application information regarding applications existing in the service, and such application information includes signal information indicating whether the application is executed on the PiP screen. Examples of application information include AIT (Application Information Table) based on the MHP standard and XAIT (eXtended Application Information Table) based on the OCAP standard, and the signal information can be added to such application information.

  Next, the restored service is set to be represented by the logical screen according to the present invention (S1020), and after mapping the logical screen to the output screen according to the present invention (S1030), the display screen 980, the recording medium 920b or The output screen is provided through the network (S1040).

  As described above, when the logical screen and the output screen are generated, when the logical screen is mapped to the output screen, or when the output screen is output, the setting module 960 sets the output screen (S1050). ). The settings performed by the setting module 960 include the first to fourth settings described above, which are user control commands input through the user / application interface module 950 or application controls that manage the operation of the setting module 960. Done by command. The detailed description of the setting has been described above with reference to FIG.

  On the other hand, in FIG. 11, it is expressed that the restored service is provided through the output screen through the logical screen, but may be provided through the output screen directly without going through the logical screen.

  In addition, when the user selects the PiP service, the PiP service is expressed as two modes, but in the first mode, a separate logical screen for the PiP service, for example, a PiP screen is not generated, and the main mode is displayed. Only the video component of the PiP service selected on the screen is represented, and in the second mode, a separate logical screen for the PiP service is generated, and the selected PiP service is represented in the generated PiP screen.

  On the other hand, FIG. 11 illustrates a process in which one service is mapped to an output screen for convenience of explanation. However, a number of services can be transmitted through a plurality of logical screens or directly by using screen attribute information. Maps to any area in the output screen.

  Thus, if the output screen is provided through a display screen, a user or application can perform a number of services.

  FIG. 12 is an exemplary diagram illustrating a software architecture for providing multiple screens according to an implementation of the present invention. Referring to FIG. 12, a software architecture 1100 according to the present invention includes a device driver layer 1110, an API (Application Program Interface) layer 1120, and an application layer 1130.

  The device driver layer 1110 receives and decodes service components constituting services from various sources providing multimedia content. At this time, examples of the service component include video information, audio information, or data information.

  The API layer 1120 generates logical screens and output screens, and performs mapping between services, logical screens, and output screens.

  The application layer 1130 provides a user interface that allows a user to dynamically configure a logical screen on which a service is represented, or transmits a user command to the API layer 1120 to perform an operation according to the command. it can.

  The operation of the application layer 1130 is performed by performing a screen search operation through a currently transmitted application or a previously stored application.

  Meanwhile, the user can output the output screen to the device driver layer 1110 through the application layer 1130 through a physical display screen, or save the output screen in the recording medium 920b. Further, the output screen can be transmitted to another device through the network by the device driver layer 1110.

  To this end, the device driver layer 1110 may include multiple output ports that provide the output screen, but multiple output ports may be present in the API layer 1120.

  On the other hand, in order to dynamically configure a large number of logical screens on the output screen, the API layer 1120 may include a large number of software modules. Here, the 'MultiScreenManager' module, the 'MultiScreenContext' module, the 'MultiScreenContextListener' module , And the 'MultiScreenContextEvent' module will be described as an example, and the relationship between such modules is shown in FIG.

  The 'MultiScreenManager' module 1210 manages the 'MultiScreenContext' module and searches for a desired screen, informs device sharing information between screens, or plays a role of registering or canceling the 'MultiScreenContextListener' module 1250.

  The 'MultiScreenContext' module 1230 is an interface object to the screen object in connection with the screen object 1220, and the screen type of the screen object is determined as a logical screen and an output screen according to the interface operation of the 'MultiScreenContext' module 1230. Various attribute information shown in FIG. The ‘set’, ‘add’, ‘get’, and ‘remove’ interfaces are provided by the ‘MultiScreenContext’ module 1230.

  The 'MultiScreenContextEvent' module 1240 is an event class for notifying when the attribute information of the screen object 1220 is changed by the interface object 1230 of the 'MultiScreenContext' module, and the 'MultiScreenContextListener module 1250 is a This is a listener interface object embodied in a predetermined application class that wants to receive the message.

  On the other hand, the application 1260 is a module that operates in the application layer 1130. The application 1260 allows the user to select a desired service, and freely arranges a number of logical screens in a desired form on the output screen.

  Therefore, if the user dynamically arranges the logical screen and transmits a command related to the management to the MultiScreenManager module 1210, the application 1260 causes the MultiScreenManager module 1230 to perform an operation corresponding to the command through the MultiScreenContext module 1230. .

  Meanwhile, the MultiScreenContext module 1230 may manage the attribute information of the screen object 1220 shown in FIG. 6 in association with the screen object 1220, and may include various functions or methods for such management.

  Meanwhile, according to an exemplary embodiment of the present invention, the MultiScreenManager module 1210 may operate to receive service components provided from various sources from the device driver layer 1110 and represent them on a logical screen or an output screen. . Of course, such a function may be performed through a separate module (not shown).

  FIG. 14 is a flowchart illustrating a process of displaying a plurality of services on an output screen through a logical screen by each module illustrated in FIG.

  First, the MultiScreenManager module 1210 generates one output screen and logical screens as many as the number of services to be executed (S1310).

  Next, the MultiScreenManager module 1210 links each logical screen with the service received from the device driver layer 1110 (S1320). At this time, the 'addServiceContext' method of the logical screen object can be called for each logical screen using the service context object for the service to be linked as a parameter. Here, the 'addServiceContext' method is understood as a method for performing a function of connecting a logical screen and a service, and is provided by the MultiScreenContext module 1230.

  If the logical screen and the service are connected, the MultiScreenManager module 1210 connects each logical screen with the output screen (S1330). At this time, for each logical screen, the ‘setDisplayScreen’ method of the logical screen object can be called using the connected output screen object as a parameter. Here, the 'setDisplayScreen' method is understood as a method for performing a function of connecting a logical screen and an output screen, and is provided by the MultiScreenContext module 1230.

  For example, the 'setDisplayScreen' method is expressed in the form of 'public void setDisplayScreen (HSScreenscreen) throws SecurityException, IllegalStateException' which provides the function with the associated To do. At this time, the 'HSScreen' instance is preferably an output screen.

  The parameter of the 'setDisplayScreen (HSScreenscreen)' method may include 'NULL'. In this case, if the 'setDisplayScreen (HSScreenscreen)' method is executed without exception handling, the current logical screen is more than that. Not associated with the output screen.

  Then, as exception processing for the 'setDisplayScreen (HSScreenscreen)' method, a 'SecurityException' exception and an 'IllegalStateException' exception are performed.

  The 'IllegalStateException' exception is that the current screen is not a logical screen, or the output screen provided for a parameter due to the characteristics of the hardware or software platform is associated with a specific logical screen, and the current logical screen is This is done if it is not associated with the corresponding output screen.

  If the service and the logical screen, and the multiple logical screens and one output screen are connected, an output screen area representing each logical screen is set (S1340). At this time, for each logical screen, the method provided by the MultiScreenContext module 1230 can be invoked to set the area found on the output screen.

  FIG. 15 is an exemplary diagram illustrating an operation of the setting module 960 according to the embodiment of the present invention. The setting module 960 can perform the first to fourth settings 1510, 1520, 1530, and 1540 described above.

  In order to make such a setting, the setting module 960 may detect a change in the setting of the screen.

  In order to detect a setting change, the setting module 960 may detect an event reported by a 'notify' method. The 'notify' method is called when the basic HScreen or MultiScreenContext setting of the application is changed, and the parameter includes 'MultiScreenContextEvent'. Therefore, an application must register a listener in order to detect 'notify' method events.

  For listener registration and cancellation, the configuration module 960 can call the 'addScreenContextListener' and 'removeScreenContextListener' methods. The 'addScreenContextListener' method and the 'removeScreenContextListener' method are methods for registering or canceling a screen context listener, respectively, and include a 'MultiScreenContextListener' instance as a parameter.

  'MultiScreenContextEvent', which is a parameter of the 'notify' method, is a class that inherits Java.util.EventObject and is used to provide the following types of changes. That is, changes in the application's basic HSscreen, changes in the linked service context, changes in the linked output Hscreen, changes in a specified region in the linked output Hscreen, changes in the linked video output port, screen vision It is the change of the physical attribute and the change of the screen z-order.

  In order to detect such a change, the 'getId' method is used, and the 'getId' method has an integer type, and SCREEN_CANGEDED, SCREEN_CONTEXT_CHANGED CHANGED PORTEDSC Returns an identifier such as SCREEN_Z_ORDER_CHANGED.

  FIG. 16A is an example of code for detecting a setting change of the screen, and defines 'AContextListener' which is a class to be notified of the setting change, and generates an instance of the defined class. Represents registration and release as a listener.

  To perform the first setting 1510, the setting module 960 can call the 'setDisplayArea' method. The 'setDisplayArea' method is a method for changing the coordinates or size of the screen, which is provided by the 'MultiScreenConfigurableContext' class.

The 'setDisplayArea' method is called 'voidsetDisplayArea (org.havi.ui.HSScreenRectangle) throws.
It is expressed in the form of Java.lang.SecurityException, java.lang.IllegalStateException ', and logical HScreen is connected to the area of the output HScreen. The parameter “rect” means an “HSScreenRectangle” instance that clearly indicates the area of the output HScreen corresponding to the area occupied by the logical HSScreen.

  If authority is not granted, a 'java.lang.SecurityException' exception is made and the HSceen form is not 'SCREEN_TYPE_LOGICAL', or the area of the output HSscreen concatenated with the logical HSScreen is not changed, or the system If only the specific area of the output HScreen concatenated with is permanently used, a 'java.lang.IllegalStateException' exception is made.

  FIG. 16B is an exemplary diagram of a code for changing the coordinates or size of the screen, and is a code for changing the coordinates or size of the screen depending on whether it can be changed. That is, the screen coordinates and size are changed by applying the ‘setDisplayArea’ method of ‘configurableScreen’, which is an instance of the given ‘MultiScreenConfigurableContext’ class.

To perform the second setting 1520, the setting module 960 can call the 'setZOrder' method. The 'setZOrder' method is a method for changing the z-order of a logical screen, which is provided by the 'MultiScreenConfigurableContext' class. The 'setZOrder' method is called 'voidsetZOrder (inorder) throws'
It is expressed in the form of Java.lang.SecurityException, java.lang.IllegalStateException ', and the z-order of the corresponding logical HScreen is changed among the logical HScreens on the same output HScreen. The parameter “order” is an integer having a positive value and means a z-order of the corresponding logical HScreen.

  If authority is not granted, a 'java.lang.SecurityException' exception is made and the HSceen form is not 'SCREEN_TYPE_LOGICAL', or the z-order of the relevant logical HScreen is not changed, or the system is in the relevant logical HSscreen. If only the specific z-order for is permanently used, a 'java.lang.IllegalStateException' exception is made.

  FIG. 16C is an exemplary diagram of a code for changing the z-order. That is, the z-order of the corresponding logical HScreen is changed to 3 by applying the ‘setZOrder’ method of the ‘configurableScreen’ which is an instance of the given ‘MultiScreenConfigurableContext’ class.

  In order to perform the third setting 1530, the setting module 960 can call a 'getScreenConfigurations' method, a 'getScreenConfiguration' method, and a 'setScreenConfiguration' method.

  The 'getScreenConfigurations' method is used for extraction of a screen layout method provided from the multi-screen providing apparatus 900 with the returned data form being 'MultiScreenConfiguration []'.

  The 'getScreenConfiguration' method is used for extraction of the currently activated screen layout method with the data form of 'MultiScreenConfiguration'.

  If authority is not granted in the 'getScreenConfigurations' method and the 'getScreenConfiguration' method, a 'java.lang.SecurityException' exception is made.

The 'setScreenConfiguration' method is used to activate the selected screen layout scheme. The 'setScreenConfiguration' method is called 'publicvoidsetScreenConfiguration (MultiScreenConfiguration configuration) throws.
It is expressed in the form of Java.lang.SecurityException, java.lang.IllegalArrangementException, java.lang.IllegalStateException '. The parameter 'configuration' means an instance of 'MultiScreenConfiguration' indicating the screen layout method to be activated.

  If no authority is granted with the 'setScreenConfiguration' method, a 'java.lang.SecurityException' exception is made.

  The 'getScreenConfigurations' method, the 'getScreenConfiguration' method and the 'setScreenConfiguration' method are provided by the 'MultiScreenConfiguration' class, but the screen layout method provided by this class corresponds to the screen on which the application is executed. Single screen form, superposed screen form in which a single screen coexists with at least one superposed screen, a screen on which an application is executed corresponds to a logical screen mapped to the entire area of the output screen, and is mapped to the output screen Corresponding to at least one non-superimposed logical screen, superimposing PiP screen form that does not correspond to clean, superimposed PiP screen form in which the PiP screen coexists with at least one overlaid screen, at least two non-printed areas in which the screen on which the application is executed is mapped to the entire area of the output screen It corresponds to a combination of superposition logic screens, and a PoP screen form that does not correspond to a superposition screen, a PoP screen in which the PoP screen coexists with at least one superposition screen, and any one of the above forms Including at least one of the non-general forms.

  In addition, in order to confirm a specific setting form of the corresponding screen, the search module can call a 'getScreenConfigurationType' method. Here, the 'getScreenConfigurationType' method is a method for returning the setting form of the currently activated screen, and is provided by the MultiScreenConfiguration module.

For example, the 'getScreenConfigurationType' method is
'inttScreenScreenConfigurationType ()
{ReturnSCREEN_CONFIGURATION_NON_PIP,
SCREEN_CONFIGURATION_NON_PIP_WITH_OVERLAY,
SCREEN_CONFIGURATION_PIP,
SCREEN_CONFIGURATION_PIP_WITH_OVERLAY,
