Detailed description of the invention
The invention provides method and device that a kind of user interface presents, it is possible to while realizing UI design, reduce the workload of APP exploitation, reduce the homework burden of developer.
In order to make those skilled in the art be more fully understood that the present invention program, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is explicitly described, obviously, described embodiment is only the embodiment of a present invention part, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, all should belong to the scope of protection of the invention.
In description of the present invention, claims and accompanying drawing, the term " first " of appearance, " second " and " the 3rd " etc. are for distinguishing different objects, and are not intended to the specific order of description. Additionally, term " including " and " having " and their any deformation, it is intended that cover non-exclusive comprising. Such as contain series of steps or the process of unit, method, system, product or equipment are not limited to step or the unit listed, but also include step or the unit do not listed alternatively, or also include other step intrinsic for these processes, method, product or equipment or unit alternatively.
In one embodiment of the invention, the method that described user interface presents includes: when monitoring digital television application routine call entry condition and accessing menu function, obtains described entry condition and accesses the data message of menu; Data stream is generated according to described data message; Described data stream is sent to described application program so that described application program draws menu according to described data stream by call back function.
As it is shown in figure 1, Fig. 1 is a kind of prior art, in Fig. 1, the integrated use technical method of DVBC middleware is: the business function interface that application layer utilizes middleware to provide, and self-organization, safeguards related service function menu.
It is the Organization Chart that a kind of user interface that one embodiment of the invention provides presents that the core concept of the present invention refers to Fig. 2, Fig. 2.
The core concept of the present invention be maintained by middleware, the business function that embodies in each CA (CA is the abbreviation of ConditionalAccess) menu and the interactive relationship between each menu; Application layer only need to input the demands such as parameter transmission and menu content renewal realize the menu translation template of a set of satisfied requirement for the presenting of menu content, user control command transmission, user; This template can be converted to the UI data from middleware the UI menu of correspondence, is therefore no longer necessary to be concerned about implementing of each function menu.
Such as: in middleware (DTVMidware), increase CAMenuEngine module (being abbreviated as CME), thus profit CME organizes and maintenance menu structure and information, response application layer menu request event, transmit menu information to application layer.
Such as: in DTVApp (App is writing a Chinese character in simplified form of Application), the CAMenu module in MenuTranslator module (being abbreviated as MTL) alternate figures 1 is used; The menu data that the with good grounds CME transmission of major responsibility comes up draws menu, and the control instruction responding user in the menu drawn is handed down to CME.
As it is shown on figure 3, Fig. 3 is the schematic flow sheet of the method that a kind of user interface that one embodiment of the invention provides presents. Wherein, as it is shown on figure 3, the method that a kind of user interface that one embodiment of the present of invention provides presents includes herein below:
