Service according to exemplary embodiment of the present invention can be classified as abstract service and non-abstract service, as Figure 16 and shown in Figure 17.
Abstract service is not the service that the broadcast singal of transmission in real time provides, but is independent of the service of broadcast channel.Abstract service only comprises data component (promptly using) and does not comprise video component and audio component.The example of abstract service comprises the service that not binding is used that has based on the OCAP standard.
Non-abstract service is understood that the service except abstract service.
According to current exemplary embodiment of the present invention, abstract service and non-abstract service have independence.For example, can abstract service directly be set on physical display, and can on logical screen, show non-abstract service by logical screen.Then, logical screen can be mapped to the display screen that is provided with abstract service.Can pass through physical display output display screen curtain thereafter.Like this, can be independent of non-abstract service and on display screen, show abstract service.In addition, abstract service can be mapped to different logical screens with non-abstract service.Logical screen can be mapped to single display screen thereafter.In other words, can be independent of non-abstract service and on display screen, show abstract service.
According to current exemplary embodiment of the present invention, logical screen can be classified as different objects with display screen.Perhaps, screen can be used as logical screen or display screen according to the attribute information of a screen object.
That is to say, can confirm that screen is logical screen or display screen based on the type information among the attribute information of screen object.
The attribute information of screen object comprises multiple attribute: " z-Order ", " Display_Area ", " Visibility ", " Associated_Display_Screen ", " Associated_Service_Contexts " and " OutputPort ".
Figure 18 illustrates the attribute information of screen object and is used for the type of the interface of processing attribute information.
Attribute " Type " the 505th, the indication screen is the logical screen or the attribute information of display screen.
Attribute " z-Order " 510 be used for determining a plurality of logical screens along the z axle with which kind of sequence arrangement.Figure 19 is to the difference configuration of the logical screen on the combined physical display unit of the value of the attribute " z-Order " that is illustrated in logical screen.
With reference to Figure 19, first logical screen 620 and second logical screen 630 are mapped to the presumptive area of display screen 610 respectively.At length, first logical screen 620 is presented on the display screen 610, and second logical screen 630 and first logical screen 620 are presented on the display screen 610 with overlapping.In other words, the direction along the z axle is arranged in order display screen 610, first logical screen 620 and second logical screen 630.In this case, the attribute " z-Order " that the attribute of first logical screen 620 " z-Order " can the value of being set to 1, the second logical screen 630 can the value of being set to 2.The attribute " z-Order " of first logical screen 620 and second logical screen 630 can be set to any numeral or character, as long as they can represent the particular order that first logical screen 620 and second logical screen 630 are arranged along the z axle.
Attribute " Display_Area " the 520th is about the information in the display screen zone of logical screen, as Figure 20 and shown in Figure 21.
Figure 20 illustrates the whole zone that logical screen 710 is mapped to display screen 720, and Figure 21 illustrates the subregion that logical screen 730 is mapped to display screen 740.
Attribute " Display_Area " can comprise the information of the two-dimensional coordinate of the predetermined portions of specifying the display screen that logical screen is mapped to, and can comprise that perhaps the information of specifying the precalculated position on the display screen and indication logical screen depart from what the deviant of precalculated position on the display screen.
Attribute " Visibility " 530 determines that logical screen shows still demonstration invisibly visibly on display screen.Can logical screen be occurred on display screen by the value that changes attribute " Visibility " 530 or disappear from display screen.
Attribute " Associated_Display_Screen " the 540th is about the information of the display screen relevant with logical screen.The logical screen that all has nothing to do with any display screen can not be presented on the physical display or not be sent to outside output device.
Attribute " Associated_Service_Contexts " the 550th is about the information of the service context that is connected to logical screen or display screen.The service that is provided with in this service context can be displayed on logical screen or the display screen.
Attribute " OutputPort " the 560th, about the information with the device of output display screen curtain, this device comprises display screen, wire/wireless communication medium and various storage medium.
Can be provided for discerning or changing the interface of the value of the attribute shown in Figure 18.With reference to Figure 18, interface can comprise: be used to set property or with logical screen be connected to display screen interface " SET ", be used to add property value or with logical screen be connected to service interface " ADD ", be used for the interface " GET " of recognition property value and be used for the interface " REMOVE " of delete property value.These interfaces can comprise processing, function, program 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.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 about current screen.In addition, if current screen is a logical screen, but there are not screen associated, then method " getDisplayScreen (void) " return value " NULL ".
According to another example, method " public void set-Display Area (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 has the class " HScreenRectangle " of bag " org.havi.ui ", and has two-dimensional position information.The execution of method " SecurityException " and " IllegalStateException " is as the abnormal operation of method " setDisplayScreen (HScreen screen) " and carry out.When current screen is logical screen or in the part of the display screen relevant with current logical screen because the characteristic of host platform can not change the time, executing method " IllegalStateException ".
According to another example, method " getOutputArea (void) " is returned the area information of current screen as HScreenRectangle information.If current screen and display screen are corresponding, then method " getOutputArea (void) " is returned the HScreenRectangle information that has identical value with HScreenRectangle (0,0,1,1).If current screen is a logical screen, then method " getDisplayArea (void) " is returned the information in the zone on the display screen that occupies about current screen.If current screen is a logical screen, but not relevant with any display screen, method " getDisplayArea (void) " return value " NULL " then.
The particular term of Shi Yonging is meant special interface in the following description.Yet, it should be appreciated by those skilled in the art that specific function is named and only be used to indicate it functional.This detailed description of exemplary embodiment is not to want distinguishing function nominally, but distinguishes on function.
By service context is relevant with screen, can on screen, show the content in the service, below, the operation that service context is relevant with screen is meant services selection.In this case, can a screen is relevant with a plurality of service context.Can operate by services selection and show service.
The service context that is used for services selection can be used for abstract service or non-abstract service.In addition, the screen that is used for services selection can be logical screen or display screen.
Because hardware or software limitations realize that device of the present invention (for example, after a while with the multi-screen generator of describing 700) has limited services selection.
For example, when service context is used for non-abstract service, exist not allow the restriction relevant of a plurality of service context with same screen.This restriction is used to reduce the complexity that occurs when showing two or more video components and background component on a screen.If the service component of same type is distributed to screen, then be difficult to specify the service component that will be presented on the screen.For example, as shown in figure 22, when before relevant with screen 50 service context 60 comprises video component 62, do not allow to comprise that another service context 70 of new video component 72 is relevant with screen 50.
In addition, being used for a plurality of service context of abstract service can be relevant with single screen.For example, be connected under the situation of screen, can will provide second of Weather information to use in addition and be connected to screen in first application that stock information is provided.
In this exemplary embodiment, carry out the services selection operation in order to use to use, can use the interface of describing with reference to Figure 18.Specifically, provide method " addServiceContexts (ServiceContexts, associateDefaultDevices) " to carry out the relevant of service context and screen.For example, when display screen on physical display, on the corresponding screen of physical display, show the content of the service context that provides.When service context is relevant with screen, be necessary whether the service of determining can be presented on the screen, that is to say, because whether above-mentioned constraint has limited the services selection operation.
What simultaneously, method " removeServiceContext (ServiceContexts) " removal method " addServiceContexts (ServiceContexts, associateDefaultDevices) " was carried out is relevant.In addition, method " getServiceContext (Service Context) " is determined the service context relevant with screen by the services selection operation.
In this embodiment, provide method " checkServiceContextCompatibility (ServiceContexts) " whether relevant with predetermined screen to check the reservation service context.
Figure 23 is illustrated in the diagrammatic sketch that the processing of two services is set with being mapped on two logical screens of single display screen.
With reference to Figure 23, first service comprises all three service component (being video component, audio component and data component), and second service only comprises video component and audio component.Yet the present invention does not apply any restriction to service component, and the service of first shown in Fig. 8 and second service are exemplary.
As shown in figure 23, as in the prior art, show that in much at one mode first service and second serves on physical display.According to current exemplary embodiment of the present invention, can on physical display, show a plurality of services independently of one another, and the quantity that can be presented at the service on the single display screen not carried out any restriction.
Figure 24 is the block diagram of equipment that is used to provide a plurality of screens according to exemplary embodiment of the present invention.
With reference to Figure 24, be used to provide the equipment 900 of a plurality of screens to comprise digital signal processing module 940, screen generation module 950, services selection module 955, output module 960 and user/AIM 965.
