Service can be classified as abstract service and non-abstract service according to an exemplary embodiment of the present invention, shown in Fig. 4 A and Fig. 4 B.
Abstract service is not the service that is provided by the broadcast singal that is sent out in real time, but is independent of the service of broadcast channel.Abstract service only comprises data package (that is, application program), and does not comprise video component and audio-frequency assembly.Based on the OCAP standard, the example of abstract service comprises having the not service of the application of binding.
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 all have independence.For example, abstract service can directly be set on physical display by logical screen, and non-abstract service can be displayed on the logical screen.Then, logical screen can be mapped to the display screen that abstract service is set.Then, display screen can be output by physical display.Thereby abstract service can be independent of non-abstract service and be displayed on the display screen.In addition, abstract service can be mapped to different logical screens with non-abstract service.Then, logical screen can be mapped to single 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 classified as different objects with display screen.Selectively, screen can be used as logical screen or display screen according to the attribute information of a screen object.
At length, screen object is that logical screen or display screen depend on " Type " information in the screen object attribute.
The screen object attribute comprise " Type ", " z-Order ", " Display_Area ", " Visibility ", " Associated_Display_Screen ", " Associated_Service_Contexts " and " OutputPort ".
Fig. 5 illustrates the screen object of the attribute that is used to handle screen and the attribute information of interface.
Attribute " Type " 510 is used for determining that screen type is logical screen or display screen.
Attribute " z-Order " is used for determining a plurality of logical screens with what order are arranged along the z axle.Fig. 6 illustrates the configuration of the logical screen on the combined physical display unit of value of the attribute " z-Order " that is used for logical screen.
With reference to Fig. 6, 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 displayed on the display screen 610, and second logical screen 630 be displayed on first logical screen, 620 partly overlapping display screens on.In other words, display screen 610, first logical screen 620 and second logical screen 630 are arranged on the z direction of principal axis continuously.In this case, the attribute of first logical screen 620 " z-Order " can the value of being set to 1, and the attribute of second logical screen 630 " z-Order " 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 symbol, as long as these numerals or symbol can be represented the particular order that first logical screen 620 and second logical screen 630 will be arranged along the z axle.
Attribute " Display_Area " the 530th is about the information in the display screen zone of logical screen, shown in Fig. 7 A and Fig. 7 B.
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 and specify the information of logical screen the two-dimensional coordinate of the predetermined portions of mapped display screen, perhaps can comprise and specify the information and the logical screen in the precalculated position on the display screen to depart from what deviant from the precalculated position on the display screen.
It is visible or invisible that attribute " Visibility " 540 determines that logical screen is displayed on the display screen.Can make logical screen appear on the display screen or and disappear by changing the value of attribute " Visibility " 530 from display screen.
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 is not sent to outside output device.
Attribute " Associated_Service_Contexts " the 560th is about the information of the service linguistic context that is connected to logical screen or display screen.The service that is provided with in this service linguistic context can be displayed on logical screen or the display screen.
Attribute " OutputPort " the 570th, the information of the device that will be output about display screen, and 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 attribute shown in Figure 5.With reference to Fig. 5, 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; And interface " REMOVE ", be used for the delete property value.These interfaces can comprise processing, function, process respectively or carry out the method for its function.
For example, method " setVisible (boolean visible) " makes current logical screen visible or invisible.At length, answering understanding method " setVisible (boolean visible) " is to be used to set a property the interface of " Visibility ".In this case, parameter " as seen " is meant and is illustrated in the visible or sightless attribute information of current logical screen on the display screen relevant with current logical screen, and data type preferably logic as seen be worth.
When manner of execution " setVisible (boolean visible) ", if current screen is not logical screen or the attribute " Visibility " that can not change current screen owing to the characteristic of hardware or software, then can implement unusual (exceptional) operation.
Corresponding to method " setVisible (boolean visible) ", can understand, method " getVisible (void) " is the interface of the information of the attribute " Visibility " that is used to obtain current screen.Method " getVisible (void) " can determine logical screen on display screen whether as seen.If current screen is a display screen, then display screen can be continuously visible.On the contrary, if current screen is a logical screen, then current screen can be visible or sightless continuously.The return value of method " getVisible (void) " can be preferably the Boolean type.
Under the situation of utilizing method " setVisible (boolean visible) " and method " getVisible (void) ", any service can be shown or can not be displayed on the logical screen of physical display, and this depends on user's selection.
In addition, when the user wants periodically to receive any service, for example, when the terrestrial broadcast service is provided on first logical screen, and when the data broadcasting service relevant with stock information is provided on second logical screen, the information of the attribute of second logical screen " Visibility " is by periodic variation, thereby the user can receive stock information in the preset time section when receiving the terrestrial broadcast service.
According to another 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 do not have relevant screen, then method " getDisplayScreen (void) " is returned " NULL " value.
According to another example, method " public void setDisplayArea (HscreenRectangle rect) throws Security Exception, IllegalStateException " provide a kind of function that is used for current logical screen is mapped to 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.As abnormal operation to method " setDisplayScreen (HScreen screen) ", but the execution of implementation method " SecurityException " and " IllegalStateException ".At current screen is logical screen or because the characteristic of host platform, when the part of the display screen relevant with current logical screen can not change, and 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 with the identical value of HScreenRectangle (0,0,1,1).If current screen is a logical screen, then method " getOutputArea (void) " is returned the information about the zone on the display screen that is occupied by current screen.If current screen is a logical screen, but not relevant with any display screen, method " getOutputArea (void) " return value " NULL " then.
Run through the employed particular term of following description and be meant special interface.Yet, it will be understood by those skilled in the art that and name specific function simply to indicate its function.The detailed description of this exemplary embodiment is not to attempt to distinguish between the function that title rather than function is different.
