A data-playing controller includes a register for storing a plurality of control parameters, a first-in-first-out buffer (FIFO) for storing data, and a control circuit capable of accessing a memory dynamically. The register can be electrically connected to a data-playing device. The control circuit can store the control parameters via the FIFO to the memory first, and then transfer the control parameters stored in the memory via the FIFO to the register during a synchronizing blank period.

A method of image processing is provided for separating an image object from a captured or provided image according to a three-dimensional (3D) depth and generating a synthesized image from the image portions identified and selectively modified in the process. The method retrieves or determines a corresponding three-dimensional (3D) depth for each portion of an image, and enables capturing a selective portion of the image as an image object according to the 3D depth of each portion of the image, so as to synthesize the image object with other image objects by selective processing and superimposing of the image objects to provide synthesized imagery.

A clock and phase detect algorithm detects the best sample result for back-end system to recover the sample clock from front-end system. The algorithm of the present invention gets the sample result from ADC by applying slope variation sum (SPVS), which is used in turning points of sample result. The exact sample clock will always get the maximum SPVS value no matter how special or difficult the pattern is. It can detect not only most of normal patterns, but also the special patterns like block, linear piece pattern. The use of SPVS result allows back-end systems to distinguish which clock is the exact clock to sample the analog signal, and make the back-end convert quality is almost the same as the front-end. This function can be operated by system maker and maintain the quality of display automatically, no manual operation is need.

A method is for scaling data from a source data to a destination data, wherein a function f(x) is determined to describe the destination data, in which x is a deviation from a current reference point 0. Two source data of f(0) and f(1) with respect to the point 0 and the point 1 are used as reference data. The method is performed by setting an initial condition about a primary slope D =f(1)−f(0), f(0.5)=[f(1)+f(0)]/2, a gain factor G>1, and f′(0.5)=DG=[f(1)−f(0)]G The f(x) is taken by a quadratic equation of f(x)=ax2+bx+c, which should pass f(0), f(1), f(0.5) and satisfy the slope of f′(0.5). Coefficients of a, b, and, c, are respectively solved in two ranges of 0≦x

A method using a dual point cubic-like slope (DPCSC) for scaling a source data to a destination data, wherein a function f(x) is determined to describe the destination data, in which x is a deviation from a current reference point 0, and two reference data of f(0) and f(1) are used as reference data. The method comprises setting an initial condition about a slope D with respect to the function f(x) at the point 0, a gain factor G to time the slope D, and f′(0)=f′(1)=DG. The f(x) is a quadratic equation of f(x)=ax2+bx+c, which should pass f(0), f(1), and a middle point f(0.5) by a quantity of f(0.5)=[f(0)+f(1)]/2. The coefficients of a, b, and, c, are solved in two ranges of 0≦x

A low cost user interface display system, like on screen display (OSD), using texture mapping method is presented. The present invention only uses a little texture memory and can generate very fancy user interface display. With the method of texture mapping, even the low cost system can have a colorful, fancy user interface display. A user interface display apparatus using texture-mapping method, comprising a image module, texture patterns, display code-buffer, texture mixer and outline shape index generator to texture-maps the predefined image module in the mixing area with the texture patterns. For some existing OSD devices, the texture-mapping method also can provide a low cost approach to fancy the original OSD display output in the display device. Moreover, changing the texture pattern is very easy to system manufacture, and it can make the user interface looks good and different.

A display controller for displaying multiple windows and associated memory access method are provided. The display controller receives a first video source and a second video source for displaying multiple windows, and includes a line buffer, a deinterlacer, a scaler, and a memory interface unit. The line buffer buffers pixel data of a non-overlapped area of a main image associated with the first video source, and pixel data of a sub image associated with the second video source. The deinterlacer is coupled to the line buffer for selectively deinterlacing data in the line buffer. The scaler is coupled to the deinterlacer for selectively scaling data outputted from the deinterlacer. The memory interface unit is coupled to the line buffer for accessing an external memory.
