Abstract: An embedded system for processing an on-screen display (OSD) includes an input apparatus, a user interface resource storage unit and a two-dimensional (2D) graphic engine. The method for processing the OSD includes receiving a control command associated with a 2D image processing procedure, the 2D image processing procedure generating a transitional image according to a first 2D image and a second 2D image, and displaying the first 2D image, the transitional image and the second 2D image to render a three-dimensional-like (3D-like) OSD.

Abstract: A device and method for displaying a caption window is provided. The method receives a first window-defining command by a TV controller, with the first window-defining command including a first window size and first caption content. A first caption data according to the first caption content is generated and stored into a system memory. a first portion of the first caption data stored in the system memory is accessed and displayed. A first offset stored in an offset register is updated to a second offset after a predetermined period. A second portion of the first caption data is accessed and displayed according to the second offset and the first window size.

Abstract: A method for displaying caption windows in a TV system is provided. The method includes steps of receiving a first window-defining command at a first time point, receiving a second window-defining command at a second time point, and determining an output state of the window-defining commands according to a comparison result between a first global priority value corresponding to the first window-defining command and a second global priority value corresponding to the second window-defining command. The first global priority value includes a first priority value of the first window-defining command and a first age parameter. The second global priority value includes a second priority value of the second window-defining command and a second age parameter. The first and second age parameters are associated with a sequence of the first and second time points.

Abstract: A method for setting caption window attributes and an associated television system are concerned. The method includes steps of providing a plurality of attributive bit sets corresponding to a plurality of pixels in a caption; utilizing a window condition to compare the plurality of attributive bit sets in response to a setting caption window attribute command for changing window color to a destination color-change value, so as to selectively update partial bits of the attributive bit sets in response to the window condition; and displaying colors of the pixels according to the attributive bit sets and a palette, thereby changing the color of the caption window.
