Abstract service is not the service that the broadcast singal by real-time transmission provides, but is independent of the service of broadcast channel.Abstract service includes only data component (that is application program) and does not have video component and audio component.The example of abstract service comprises the service that not binding is used that has based on open cable application platform (OCAP) standard.
Non-abstract service can be regarded as the service except that abstract service.
According to current exemplary embodiment of the present invention, abstract service and non-abstract service all have independence.For example, abstract service can not be set directly on the physical display by logical screen, and non-abstract service can be presented on the logical screen.Then, logical screen can be mapped to the display screen that abstract service is set.After this, can come the output display screen curtain by physical display.Like this, abstract service can be independent of non-abstract service and be presented on the display screen.In addition, abstract service can be mapped to different logical screens with non-abstract service.After this, logical screen can be mapped to single display screen.In other words, abstract service can be independent of non-abstract service and be presented on the display screen.
According to current exemplary embodiment of the present invention, logical screen and display screen can be categorized as different objects.Perhaps, screen can be used as logical screen or display screen according to the attribute information of a screen object.
At length, if having predetermined value and other screen object attribute has fixing value corresponding to the screen object attribute of the characteristic of logical screen, then screen object can be used as logical screen.In other words, if having predetermined value and other screen object attribute has fixing value corresponding to the screen object attribute of the characteristic of logical screen, then screen object can be used as display screen.
The attribute information of screen target comprises a plurality of attributes: " z-Order ", " Display_Area ", " Visibility ", " Associated_Display_Screen ", " Associated_Service_Contexts ", " Associated_Logical_Screen " and " OutputPort ".
If attribute " z-Order ", " Display_Area ", " Visibility ", " Associated_Display_Screen " and " Associated_Service_Contexts " have predetermined value and attribute " Associated_Logical_Screen " and " OutputPort " and have fixed value, then screen object can be used as logical screen.
On the other hand, if attribute " Associated_Service_Contexts ", " Associated_Logical_Screen " and " OutputPort " have predetermined value and attribute " z-Order ", " Display_Area ", " Visibility " and " Associated_Display_Screen " has fixed value, then screen object can be used as display screen.
Fig. 5 illustrates the attribute information of logical screen and display screen and the diagrammatic sketch of interface.
With reference to figure 5, attribute " Type " 510 is used for determining screen type-logical screen or display screen.
Attribute " z-Order " 520 is used for determining a plurality of logical screens with what order are arranged along the z axle.Fig. 6 (a) and Fig. 6 (b) illustrate the different configurations of the logical screen on physical display of various combination of the value of the attribute " z-Order " that is used for logical screen.
With reference to figure 6 (a), 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 at display screen 610, the second logical screens 630 and is presented at and first display screen, 620 partly overlapping display screens.In other words, display screen 610, first logical screen 620 and second logical screen, 630 sequence arrangement are on the direction of z axle.In this case, the attribute " z-Order " of first logical screen 620 can be set to 1, the attribute " z-Order " of second logical screen 630 can be set to 2.The attribute " z-Order " of first logical screen 620 and second logical screen 630 can be set to any numeral or symbol, as long as the particular order that on behalf of first logical screen 620 and second logical screen 630, they can arrange along the z axle.
With reference to figure 6 (b), when the value of the attribute " z-Order " of first logical screen 620 shown in Fig. 6 (a) becomes 2 by 1, and the value of the attribute of second logical screen 630 " z-Order " becomes at 1 o'clock by 2, and first logical screen 620 and second logical screen 630 are mapped to the presumptive area of display screen 610 respectively.In this case, display screen 610, first logical screen 620 and second logical screen 630 according to the value sequence arrangement of the change of attribute " z-Order " on the direction of z axle.
As mentioned above, the order of a plurality of logical screens arrangements of attribute " z-Order " indication.Attribute " z-Order " also can specify in the order of the component arrangement of logical screen or display screen.
For example, as mentioned above, logical screen or display screen can be the combinations of stationary background image, video raster and figure grating.Simple for what describe, (for example provide the stationary background image, background image) example (or object) will be called as " HBackgroundDevice ", provide video (for example, moving image) example (or object) will be called as " HVideoDevice ", provide the example (or object) of figure (for example, application data) will be called as " HGraphicsDevice ".In addition, example (or object) " HBackgroundDevice ", " HVideoDevice " and " HGraphicsDevice " will be collectively referred to as " HScreenDevice ".
Here, can determine the order of the example " HScreenDevice " of on z direction of principal axis permutation logic screen or display screen.
Preferably, with " HBackgroundDevice ", " HVideoDevice " and " HGraphicsDevice " sequence arrangement.Therefore, the value of the attribute " z-Order " of example " HVideoDevice " is greater than the value of the attribute " z-Order " of example " HBackgroundDevice ", and the value of the attribute " z-Order " of example " HGraphicsDevice " is greater than the value of the attribute " z-Order " of example " HVideoDevice ".
If there is example " HBackgroundDevice " in current screen, the value of attribute " z-Order " of example " HBackgroundDevice " that then is placed on the extreme lower position (being seen as at current screen backmost from observer's viewpoint) of current screen is 0.
If current screen does not have example " HBackgroundDevice ", and example " HVideoDevice " is arranged, the value of attribute " z-Order " of example " HVideoDevice " that then is placed on the extreme lower position (being seen as at current screen backmost from observer's viewpoint) of current screen is 0.
If current screen had not both had example " HBackgroundDevice " not have example " HVideoDevice " yet, the value of attribute " z-Order " of example " HGraphicsDevice " that then is placed on the extreme lower position (being seen as at current screen backmost from observer's viewpoint) of current screen is 0.
In addition, the value of attribute " z-Order " that is included in the example " HVideoDevice " in the current screen is greater than the value of the attribute " z-Order " that is included in any example " HBackgroundDevice " in the current screen, and the value of attribute " z-Order " that is included in the example " HGraphicsDevice " in the current screen is greater than the value that is included in any example " HVideoDevice " attribute " z-Order " in the current screen.Because these " HScreenDevice " with value of bigger attribute " z-Order " are placed on the front near current screen, so they and observer's distance is shorter.
When coming example alignment " HBackgroundDevice ", " HVideoDevice " and " HGraphicsDevice " with aforesaid order, can determine the putting in order of example " HScreenDevice " of same type arbitrarily.
Example " HGraphicsDevice " can comprise a plurality of examples (or object), and each forms be called as " HScene " of example " HGraphicsDevice ".Each example " HScene " can be understood that to carry out the air-frame of application, and a plurality of application can be gone up at an example " HScene " and be carried out.Can determine the putting in order of example " HScene " in example " HGraphicsDevice " by attribute " z-Order ".Just, attribute " z-Order " can be indicated putting in order of logical screen, and perhaps the component of logical screen or display screen puts in order.In addition, attribute " z-Order " can be indicated the putting in order of component of example " HGraphicsDevice ".
Discern putting in order of example " HScene " for use attribute " z-Order ", class object " HSceneManager " is set up.Class object " HSceneManager " can obtain the attribute " z-Order " of example " HScene ".
Class object " HSceneManager " becomes applications registry to be used for the processor of the change of handling all examples " HScene " that belong to example " HGraphicsDevice ".
Shown in Fig. 7 (a) and Fig. 7 (b), attribute " Display_Area " the 530th is about the information in the display screen zone of logical screen.
Fig. 7 (a) illustrates the whole zone that logical screen 710 is mapped to display screen 720, and Fig. 7 (b) 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 maybe what deviant the information that specifies in the precalculated position on the display screen and indication logical screen have been offset from the precalculated position on the display screen.
Attribute " Visibility " 530 determines that logical screen still invisibly is presented on the display screen visibly.Logical screen is disappeared in the display screen appearance or from display screen.
Attribute " Associated_Display_Screen " the 540th is about the information of the display screen relevant with logical screen.The logical screen relevant with any display screen can not be presented on the physical display, and can 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 " Associated_Logical_Screen " the 560th is about the information of the logical screen relevant with display screen.
Attribute " OutputPort " the 570th, about the information of the device of output display screen curtain, this device comprises display screen, wire/wireless communication medium and various storage medium.
The interface that is used to discern or change the value of attribute as shown in Figure 5 can be provided.With reference to figure 5, this interface can comprise: " SET " interface, the value that is used to set a property or logical screen is connected to display screen; " ADD " interface is used to add the value of attribute or logical screen is connected to service; " GET " interface is used for the value of recognition property; " REMOVE " interface is used for the value of delete property.These interfaces can comprise processing, function, process or the method for carrying out its function separately.
For example, method " setZOrder (int order) " is provided with or changes aforesaid attribute " z-Order ".Parameter " order " is meant the attribute information that is presented at the order of display screen interval scale display logic screen when logical screen.At length, method " setZOrder (int order) " is to be used to set a property the interface that is provided with of " z-Order ".
But the abnormality processing of implementation method " setZOrder (int order) ".When current screen is not that the attribute " z-Order " of logical screen or current screen is because the characteristics of hardware or software and can implement this abnormality processing can not be changed the time.
Corresponding to method " setZOrder (int order) ", method " getZOrder (viod) " is provided at the attribute information of " z-Order " in the current screen and need not any parameter, and returns the value of non-negative " z-Order ".If current screen is a display screen, method " getZOrder (viod) " preferably returns 0, and logical screen preferably has the natural number greater than 1.Method " getZOrder (viod) " be used to obtain attribute " z-Order " information obtain interface.
In addition, method " setZOrder (HScreenDevice[]) " is provided with or changes the value of the attribute " z-Order " of the example " HScreenDevice " in logical screen or display screen.The parameter of method " setZOrder (HScreenDevice[]) " is the set of the value of its attribute " z-Order " example " HScreenDevice " that will be set up or change.At length, method " setZOrder (HScreenDevice[]) " be used to be provided with example " HScreenDevice " " z-Order " attribute information interface is set.
