Abstract: PURPOSE: A method for correcting a focus in a monitor system is provided to adjust gain of an inputted video signal by use of the parabola signal, of which level increases in proportion to reaching an edge of a screen, so as to prevent defocusing at the edge thereof. Also, in association with adjustment of contrast or sub contrast, a waveform of a parabola signal is automatically varied through a parabola signal generating circuit, so that the focus of the edge is efficiently corrected. CONSTITUTION: In a method for correcting a focus at an edge of a screen, a first signal having a level corresponding to a first control signal, is generated. Next, a horizontal parabola signal is generated, which is synchronized to a horizontal flyback pulse(HFBP), and can be varied according to the first signal and a second control signal. Next, the first signal and the horizontal parabola signal are synthesized, to generate a parabola signal, of which level rises in proportion to going to the edge of the screen. Last, adjusting a gain of an inputted video signal leads to correct the focus, so that the gain gets to be higher around the screen.

Abstract: PURPOSE: A method and a system are provided for timing recovery of a sine curve preamble with a short loop waiting time. CONSTITUTION: By obtaining coefficient in advance, the phase shift of an FIR filter is estimated and the phase error of input to the FIR filter (201) is determined. Because of asymmetric setting of the coefficient, phase shift through the FIR is not zero. For preferable execution example, the duration of an acquisition mode timing loop is decreased by eliminating the duration of the FIR filter (201) itself. The coefficient is programmed in a memory (205) or applied as a part of LMS application. Because of inference, multiplying operation is avoided and adding operation and a single divider are used. The inferred partial phase error is next totaled by a 'FIR bypass mode' phase detector (204) and entire shift is provided.
