Embodiment
Under set hardware platform; the present invention is by the reasonable management and control to intelligent television large data placard information; dynamically memory management not only can effectively protect intelligent television product; internal memory can be caused when avoiding a large amount of placard picture to load to rise suddenly and sharply the problem that movement can be made to generate heat rapidly; extend product useful life; and when user carries out video request program preview; effectively can promote video placard information and load the speed refreshed; solve the problem that user focus switch card pauses simultaneously, improve the fluency of Consumer's Experience.
This routine technical scheme realizes as follows:
Create data page display model by 3D modeling software blender in prior art, in 3D interactive interface, various animation effect can be realized very easily, and animation effect is smooth, vividly.Data page display model quantity is determined jointly by intelligent television display layout and animation effect.The stored memory that supposing the system distributes to video placard image data is N, and every page of 12 data models in 3D model.Store M can only open placard data under set internal memory N, therefore M need be the integral multiple of 12.
The conversion of placard pictorial information, the placard pictorial information that intelligent television obtains from the Internet is all png, jpg form, and playing up of 3D model carries out graph rendering by calling Android OpenGL ES2.0 interface, it is Bitmap form that picture is played up in requirement, 3D data model is by managing texture and material in addition, and texture and material not only comprises the texture information of picture, also has illumination, shadow informations etc., this example has only used the picture texture information in texture and material.User is when carrying out video request program preview, placard picture number is huge, and data display model quantity is certain, therefore must bind dynamically to tie up with solution to model and placard picture texture and operate to ensure that the correct of placard pictorial information mates, these are all current those skilled in the art's common technology means, explain no longer further herein.
In order to promote key response and placard Data import refresh rate, the Focal Point Shift of intelligent television is movably arranged in main thread by this example, OpenGL ES2.0 graph rendering is movably arranged in 3DUI thread, the loading of placard picture, the refreshing of placard picture and memory management are movably arranged in Buffer thread, achieve the preemptive type management of multitask like this.
The loading of placard picture, refreshing, memory management activity, inside same thread, carry out user the process that video request program page turning preview all can see a placard Data import, refreshing so at every turn.Therefore, in order to placard loading efficiency can be promoted further, time at one's leisure, namely user is when carrying out video request program preview, 5 seconds when not carrying out any button operation, system carries out prestrain to placard picture on backstage automatically, and like this when user's page turning preview, very fast just plays up out by placard picture.
