Abstract: An apparatus for calibrating an optical storage device includes a clock generator, a jitter meter, and a calculation unit. The clock generator is utilized for providing a clock signal; the jitter meter is utilized for obtaining a plurality of data-to-data jitter values of a plurality of radio frequency (RF) signals according to the clock signal; and the calculation unit is utilized for determining a minimum jitter value among the plurality of data-to-data jitter values.

Abstract: A method for processing an audio/video bit-stream includes the steps of receiving an input bit-stream, detecting whether the input bit-stream has a startcode emulation prevention pattern, and removing the startcode emulation prevention pattern from the input bit-stream to generate an output bit-stream and setting a flag signal as a first designated flag value when the startcode emulation prevention pattern is detected. The method further includes the step of detecting whether the input bit-stream includes a startcode, and directly outputting the input bit-stream and setting the flag signal as a second designated flag value when the startcode is detected.

Abstract: A method for tracking and focusing enhancement of disk drives and related devices. The method performs feedforward compensation for an output signal generated by a feedback compensator of a disk drive. The output signal is utilized for controlling a tracking position or a focusing position of a read/write module of the disk drive. The method includes obtaining the output signal, within which a dominant signal is a periodic wave corresponding to a tracking error or a focusing error of the disk drive, identifying a waveform of the dominant signal, generating a correction signal according to the waveform of the dominant signal, and superposing the correction signal on the output signal to correct the dominant signal.
