Abstract: The present invention relates to an apparatus and a method of detecting a sync pattern. The method includes the steps: creating a plurality of windows by dividing a data stream by a preset unit length and arranging the windows in parallel to each other to form a matrix; performing a transform process of sequentially dividing a bitstream of the window by 4 bits and converting the bitstream in a hexadecimal format; repeating the transform process by shifting the window by one bit; counting a repetition frequency of a plurality of sequences, which is created by grouping the transformed hexadecimal numbers by a preset digit number, within a plurality of windows; marking a position of a sequence having the repetition frequency exceeding a preset threshold value by a predetermined marker; deducing straight lines having the same slope, which connect markers to each other based on the positions of the markers marked on the matrix; and detecting a sync pattern based on the bitstream of the window matched with the marker on the straight line. The periodicity of a received data stream is detected by making the data stream in the form of an image even when a frame length, a position of the sync pattern, and a length of the sync pattern are not given, so that the sync pattern can be detected.

Abstract: PURPOSE: A direction detecting device is provided to improve a direction-detection accuracy by adding a weight to a portion where the accuracy is excellent. CONSTITUTION: A direction detecting device comprises a calculation block(610) which converts video signals of odd and even channels to measure maximum values of odd and even channels. A selector calculating part(620) receives the maximum values from the calculation block(610) to calculate a sector value. A channel compensating block(630) compensates the nonlinear characteristics with regard to an output signal of the calculation block(610) with reference to the sector value. An amplitude difference calculating block(640) calculates an amplitude difference of the odd channel and an amplitude difference of the even channel, and an amplitude difference of adjacent beams in response to an output signal of the block(630). A period direction calculating block(650) calculates period directions of the odd and even channels and of the adjacent beams. An intersection amplitude period direction calculating part(660) obtains a channel amplitude difference by comparing the period directions from the block(650) with a sector direction of the calculation part(620), and calculates a direction of a mixing amplitude period by adding a weight to a sector where a direction-detection accuracy is stable.
