Each pixel of the image of the CPU pointwise traversal user interface of step 20, TV box, judges whether the Alpha value in each pixel ARGB equals 0; Be, do not operate, flow process finishes; No, enter step 30;
The image data format that the frame buffer layer of step 30, judgement TV box is supported is RGB888 or RGB565, is RGB888 form, and the B component value of the point that is 0 by the B component of all image slices vegetarian refreshments of the user interface in frame buffer layer is all set to 1; Be RGB565 form, the B component value that the B component of all image slices vegetarian refreshments of the user interface in frame buffer layer is less than to 8 point is all set to 8, thereby the black region at completing user interface also can show on video playback interface.
Further, between step 10 and step 20, further comprising: the video of step 11, TV box is when broadcast state, the view data of user interface is stored in a buffer area, when user carries out vision operation, on video, eject user interface, now by the image data transmission of user interface to frame buffer this layer.
Tool of the present invention has the following advantages: whether the present invention needs to show according to the black region in user interface, each pixel ARGB value and the Alpha value of black region is set; Each pixel of the image of the CPU pointwise traversal user interface of TV box, the Alpha value of finding out in each pixel ARGB is not equal to 0 point; The form of supporting according to frame buffer layer, the B component of image slices vegetarian refreshments is processed, thereby the black region at completing user interface also can show on video image simultaneously.When the present invention has realized video playback, when the black region of part appears in user interface, can not be filtered, can show, improve user's experience.
