Abstract: PROBLEM TO BE SOLVED: To provide an improved digital to analog converter circuit of an LCD panel column driver. SOLUTION: The digital to analog converter (DAC) circuit operates over an upper range and a lower range. An upper voltage node is designated AVDD; a middle voltage node is designated HVDD; and a lower voltage node designated ground. An upper DAC stage has at least one NMOS transistors that produces an output to an upper range output node when the output is in the upper range. A lower DAC stage has at least one PMOS transistors that produces an output to a lower range output node when the output is in the lower range. A body bias control circuit couples the body of the upper NMOS transistor to a voltage source equal to HVDD-Vbe and connects the body of the lower PMOS transistor to voltage source equal to HVDD+Vbe.

Abstract: PROBLEM TO BE SOLVED: To solve a problem of stereo sound playback in at least 5.1 speakers system and resolve scalability issues in standpoints of calculation and memory use. SOLUTION: The invention adopts a multi-band processing to allow to handle different frequency bands separately. This achieves better channel separation when more than one dominant signals exist in an arbitrary time. Since chances in which a dominant band falls into different frequency bands as the number of the frequency bands increases, uncertainness in decoding decreases. A problem of a plurality of dominant signals is decreased by implementing slow attenuation of surround signal when one dominant central signal exists and vice versa. This is based on an assumption that not all dominant signals are always active. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: The invention relates to a method of motion estimation for use in a video picture encoder. A first macroblock of a present picture is compared with a plurality of macroblocks within a search window of a previous or next picture for determining a second macroblock within the search window which is spatially displaced from the first macroblock by an amount represented by a motion vector at a full pixel resolution level. The comparison of the present picture and the previous or next picture is performed by the encoder using packed operations. The method includes the step of storing each pixel of the first macroblock or the search window using two bytes per pixel for avoiding byte misalignment during the packed operations.

Abstract: In a communications system having incoming communications signals and outgoing communications signals the outgoing communications signals may undesirably include an echo signal derived from the incoming communications signals. Accordingly, echo cancellation techniques may be applied in the communications system, incluiding generating weighting filter coefficients based on linear prodictive coding coefficients calculated from a block comprising a plurality of sequential samples of the incoming communications signals. The incoming communications signals are filtered through a weighting filter utilising the weighting filter coefficients to produce a weighted incoming communications signals. Estimated echo signals are generated by filtering the incoming communications signals through an adaptive transversal filter, the adaptive transversal filter using adaptive filter coefficients. Then, the estimated echo signals can be subtracted from the outgoing communications signals to produce error signals. Advantageously, the adaptive filter coefficients are determined for each sample in said block on the basis of the weighted incoming communications signals and the error signals.
