Abstract
Video display apparatuses and display methods thereof. The apparatus includes a first buffer, a second buffer, a third buffer, a blending engine and a display engine. The first buffer stores a video source. The second buffer stores on screen display (OSD) source data. The third buffer stores a parameter for a transparent effect, and position information corresponding to at least one partition, in which the parameter determines the transparency of the video source in the partition. The blending engine performs the transparent effect on the video source and the OSD source data according to the parameter and the position information, thus generating blended source data. The display engine fetches and displays the blended source data from the blending engine on a display device.
