Then, will serve arbitrarily by predefined method or by the method for user or application program setting and be set directly on the display screen that to be presented on the physical display.In addition, at least one logical screen that is mapped to the arbitrary region of display screen is presented on the physical display 350.In brief, the service that is provided by terrestrial broadcasting merchant 320, wired broadcasting merchant 330 and PVR is displayed on the physical display 350.
Shown in Fig. 5 A and Fig. 5 B, service can be divided into abstract service (abstract service) and non-abstract service (non-abstract service) according to an exemplary embodiment of the present invention.
Abstract service is not the service that broadcast singal provided of real-time Transmission, but is independent of the service of broadcast channel.Abstract service only comprises the broadcast data component, i.e. application program, and do not comprise video component and audio frequency component.The example of abstract service comprises the service with measured not binding application program.
Non-abstract service is considered to the service except abstract service.
According to current exemplary embodiment of the present invention, abstract service and non-abstract service are independently.For example, abstract service can not be set directly on the physical display by logical screen, and non-abstract service can be displayed on the logical screen.Then, described logical screen can be mapped to the display screen that is provided with abstract service.Afterwards, can pass through physical display output display screen curtain.Like this, abstract service can be independent of non-abstract service and is displayed on the display screen.In addition, abstract service can be mapped to different logical screens with non-abstract service.Afterwards, these logical screens can be mapped to a display screen.In other words, abstract service can be independent of non-abstract service and is displayed on the display screen.
According to current exemplary embodiment of the present invention, logical screen can be divided into different objects with display screen.Alternatively, according to the attribute information of a screen object, screen can be used as logical screen or display screen.
Say that at length screen object is that logical screen or display screen depend on " Type (the type) " information in the attribute of screen object.
The attribute of screen object comprises " Type ", " z-Order (z order) ", " Display_Area (viewing area) ", " Visibility (visuality) ", " Associated_Display_Screen (relevant display screen) ", " Associated_Service_Contexts (related service context) " and " OutputPort (output port) ".
The interface that Fig. 6 illustrates the attribute information of screen object and is used to handle the attribute of screen.
Attribute " Type " 510 is used for determining that screen type is logical screen or display screen.
Attribute " z-Order " 520 is used for determining the ordering of a plurality of logical screens along the z axle.Fig. 7 illustrates the combination for logical screen " z-Order " property value, the configuration of the logical screen on the physical display.
With reference to Fig. 7, first logical screen 620 and second logical screen 630 are mapped to the presumptive area of display screen 610 respectively.Say that at length first logical screen 620 is displayed on the display screen 610, second logical screen 630 and first logical screen 620 are presented on the display screen with overlapping.In other words, display screen 610, first logical screen 620 and second logical screen 630 are disposed in order along the z direction of principal axis.In this case, " z-Order " attribute that " z-Order " attribute of first logical screen 620 can the value of being set to 1, the second logical screen 630 can the value of being set to 2." z-Order " attribute of first logical screen 620 and second logical screen 630 can be set to any numeral or character, as long as the certain order that first logical screen 620 and second logical screen 630 are arranged along the z axle can be represented in these numerals or character.
Attribute " Display_Area " the 530th is with the relevant information in display screen zone (shown in Fig. 8 A and Fig. 8 B) of logical screen.
Fig. 8 A illustrates the whole zone that logical screen 710 is mapped to display screen 720, and Fig. 8 B illustrates the subregion that logical screen 730 is mapped to display screen 740.
" Display_Area " attribute can comprise specifies the information of logical screen with the two-dimensional coordinate of the predetermined portions of the display screen that is mapped to, perhaps can comprise what deviant the precalculated position of specifying on the display screen and logical screen have been offset with respect to the described precalculated position on the display screen information.
Attribute " Visibility " 540 definite logical screens will visually be presented on the display screen still will be presented on the display screen not visiblely.Can logical screen be appeared on the display screen or from display screen by the value that changes attribute " Visibility " 540 disappears.
Attribute " Associated_Display_Screen " the 550th is about the information of the display screen relevant with logical screen.Not relevant with any display screen logical screen can not be displayed on the physical display, also can not be transferred to outside output device.

Attribute " OutputPort " the 570th, with the information that the device of output display screen curtain is relevant, such device comprises indicator screen, wire/wireless communication medium and various medium.
Can provide shown in Figure 6 being used to discern or change the interface of property value.With reference to Fig. 6, described interface can comprise: interface " Set " is used to set property or logical screen is connected to display screen; Interface " Add " is used to add property value or logical screen is connected to service; Interface " Get " is used for the recognition property value; Interface " Remove " is used for the delete property value.These interfaces can comprise process, function, process or the method for the function of carrying out them respectively.
For example, method " getDisplayScreen (void) " is returned the display screen relevant with current screen.Say that at length if current screen is a logical screen, then method " getDisplayScreen (void) " is returned relevant display screen.If current screen is a display screen, then method " getDisplayScreen (void) " is returned the reference information relevant with current screen.In addition, if current screen is a logical screen, but do not have screen associated, then method " getDisplayScreen (void) " is returned " NULL " value.
According to another example, method " public void setDisplayArea (HScreenRectangle rect) throws SecurityException, IllegalStateException " is provided for current logical screen is mapped to the function of the presumptive area of relevant display screen.The example that is provided as parameter is the class " HScreenRectangle " of bag " org.havi.ui ", and has two-dimensional position information.Can carry out the execution of method " SecurityException " and " IllegalStateException ", as the exception operation of method " setOutputScreen (HScreen screen) ".Can be when current screen be logical screen, perhaps in the part of the display screen relevant with current logical screen because the characteristic of host platform and can not change the time, manner of execution " IllegalStateException ".
According to another example, method " getOutputArea (void) " is returned the area information of current screen as HScreenRectangle information.If current screen is corresponding to display screen, then method " getOutputArea (void) " is returned its value and the identical HScreenRectangle information of HScreenRectangle (0,0,1,1).If current screen is a logical screen, then method " getOutputArea (void) " return with display screen on the relevant information in zone that occupied by current screen.If current screen is a logical screen, but this screen and any display screen are all uncorrelated, and then method " getOutputArea (void) " is returned " NULL " value.
All the time use particular term to represent special interface in the following description.Yet, it should be appreciated by those skilled in the art that the specific function name just in order to represent its function.Detailed description to exemplary embodiment is not to be in order to distinguish the function of title difference (and not function difference).
Fig. 9 illustrates the diagrammatic sketch that two services are set at the process on two logical screens that are mapped to a display screen.
With reference to Fig. 9, first service comprises all three service components, i.e. video, audio frequency and data component, and second service only comprises video and audio frequency component.Yet the present invention does not force any restriction to the service component, and first service and second service shown in Figure 8 only are schematic.
