Patent ID: 8160428

Claim:
A video player providing a video signal to a display device, comprising: a selection unit outputting a first signal of an interlaced format or outputting a second signal of a progressive format according to a state of a selection signal; a frequency generator outputting a first frequency or a second frequency according to the state of the selection signal, wherein the selection unit outputs the first signal of the interlaced format when the selection signal is at a first logic level, and the selection unit outputs the second signal of the progressive format when the selection signal is at a second logic level; an adjuster executing a first operation with the signal output from the selection unit for generating a process signal according to the frequency output from the frequency generator, wherein the frequency generator outputs the first frequency when the selection signal is at the second logic level, and the frequency generator outputs the second frequency when the selection signal is at the first logic level; and a processor executing a second operation with the process signal for generating the video signal.
