PURPOSE: A motion vector extractor based array and method thereof are provided to minimize delay time by reading motion and writing motion of a memory. CONSTITUTION: A comparison operation unit(20) includes a plurality of comparators. The plurality of comparators receive a current SAD(Sum of Absolute Difference) value outputted from a relevant SAD tree block among a plurality of SAD tree blocks. The plurality of comparators compares the current SAD value and existing calculated SAD value. A motion vector merger(22) combines a motion vector values of pixels based on a comparison result values of the plurality of comparators and arranged the motion vector values.
Abstract:
A small low-power embedded system and a preemption avoidance method thereof are provided to avoid preemption of a task based on dual priority scheduling while guaranteeing simultaneous operations of tasks. At least one periodic task is registered in a periodic run queue(110). At least one aperiodic task is registered in an aperiodic run queue(120). At least one device is used in running the periodic and aperiodic tasks. A scheduler(150) periodically runs a periodic task of the periodic run queue. The scheduler periodically runs an aperiodic task of the aperiodic run queue. The scheduler runs the periodic task and the aperiodic task by avoiding preemption of a task based on dual priority scheduling while guaranteeing simultaneous operations of tasks.
Abstract:
A device and a method for detecting STBC(Space-Time Block Coding) are provided to improve a detection performance of STBC-OFDM(Orthogonal Frequency Division Multiplexing) by removing erroneous propagation of a DF(Decision Feedback). A device for detecting STBC includes a matching filter(100), and whitening filters(110a,110b). The matching filter(100) receives a demodulation symbol of a base band, and has a filter coefficient of h^H. The first and second whitening filters(110a,110b) receive an output of the matching filter(100), and has filter coefficients of (R1^H)^-1 and (R2)^-1. The device for detecting the STBC transmits data x=[x1,x2]^T through two transmission antennas. The device for detecting the STBC detects data x^=[x1^,x2^]^T from a demodulation symbol y=[y1,y2]^T of the base band which is demodulated from the signal received through two receiving antennas.

Abstract:
A DMB(Digital Multimedia Broadcasting)/DAB(Digital Audio Broadcasting) receiver and a method for receiving the DMB/DAB by using the receiver are provided to offer audio/video/data service information through a screen and a speaker of a TV by using a PIP(Picture In Picture) function of the TV. A DAB/DMB receiving module(260) receives DAB/DMB signal through an antenna and outputs audio/video/data service information to a control member(210) of a television system(200). The control member outputs the received audio/video/data service information to output devices corresponding to each data. A PIP control member(220) produces a video screen so that a PIP type screen is displayed by the received audio/video/data service information.
