Abstract: A video signal processing method includes: a step for deriving an intra prediction mode of a current block; a step for constructing a reference sample around the current block; a step for generating a prediction sample of the current block by using the reference sample on the basis of the intra prediction mode; and a step for restoring the current block on the basis of the prediction sample. The step for generating the prediction sample may include: a step for setting a filter flag value which specifies a filter coefficient of an interpolation filter applied to the reference sample on the basis of the width and height of the current block; and a step for performing filtering on the reference sample by using the interpolation filter having the filter coefficient specified by the filter flag.

Abstract: The clock generator is provided and includes a phase detector, a voltage generator, a voltage-to-current converter, and an oscillation circuit. The voltage generator generates a control voltage. The voltage-to-current converter converts the control voltage into an internal current having a level based on a resistance value of a resistor circuit, the resistance value set based on first control information. The oscillation circuit generates a output clock having a frequency based on the level of the internal current and a capacitance value of a capacitor circuit, the capacitance value set based on second control information. The clock generator maintains a frequency value and varies jitter characteristics of the output clock in response to the first control information and the second control information.
