20110254814 | SYSTEM AND METHOD FOR HANDLING IMAGE DATA TRANSFER IN A DISPLAY DRIVER - In a display driver, image data are assembled with synchronization information to form a stream of digital data. The stream of digital data is transmitted from a timing controller to a data driver along with a timing signal having phase-delayed pulses obtained from an external clock received by the timing controller. In response to the timing signal, the data driver can extract a synchronizing signal from the synchronization information embedded in the stream of digital data, and use the synchronizing signal for generating an internal clock signal. Encoded image data in the stream of digital data then can be retrieved according to the internal clock signal. | 10-20-2011 |
20110250860 | RECEIVER AND METHOD FOR DYNAMICALLY ADJUSTING SENSITIVITY OF RECEIVER - A receiver and a method for dynamically adjusting sensitivity of the receiver are provided. The receiver includes a detection unit and a receiving unit. The detection unit detects an input signal group, and outputs a detection result. The receiving unit receives the input signal group according to a sensitivity. Wherein, the receiving unit dynamically adjusts the sensitivity used for receiving the input signal group according to the detection result of the detection unit. | 10-13-2011 |
20110249870 | METHOD OF OCCLUSION HANDLING - In a method of occlusion handling, a reference frame and a current frame are first provided, and at least one foreground object is determined. At least a covered region or an uncovered region with respect to the foreground object is determined. The covered region is then interpolated exclusively accordingly to the current frame, or the uncovered region is interpolated exclusively according to the reference frame. | 10-13-2011 |
20110249188 | METHOD OF BLOCK-BASED MOTION ESTIMATION - In a method of block-based motion estimation a motion vector map is obtained by obtaining a motion vector of each macroblock (MB) in the current frame with respect to the reference frame. The motion vector of each MB in an interpolated frame is then determined according to the motion vector map. | 10-13-2011 |
