Abstract

The invention discloses a display system and a display method applied to an embedded digital entertainment on-demand system. The method includes the steps: dividing image data about to be displayed in display equipment into a background layer and a text layer by means of layering technology, and dividing a text layer area into at least two blocks including a text display area and a text preparation area outside the display area respectively, wherein each of the background layer and the text layer is in a memory compatible DC (dual channel) form; stacking the text display area of the text layer with the background layer of a display area of the display equipment, storing the stacked text display area and the background layer into a frame, and outputting the frame to the display equipment for display; and moving the text layer relative to a background layer area, generating data after the text layer is moved every time to be stacked with the background layer and outputting the data to the display equipment for display. The display system and the display method are capable of improving efficiency of scroll captions in the embedded digital entertainment on-demand system.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a display system and method applied to an embedded digital entertainment on-demand system. Background technique [0002] In the production process of existing multimedia or web works, rolling subtitles (also known as revolving lanterns) is a display effect that is often used, and the fade-in and fade-out effect is often used; it can make our messages more humane However, this function is rarely available in embedded products. In the existing text revolving lantern application of the digital entertainment on-demand system, the revolving revolving lantern is also directly output to the screen. There is no effective transition effect, which directly leads to the revolving lantern It is very abrupt to break directly during the movement. And this method directly violates the smooth, dazzling, and cool elements of the entertainment on-demand system. [0003] Moreover, in the abov...
