Abstract: A method and system of automatically correcting a sampling clock in a digital video system are disclosed. Sampling clocks with different phases are generated and subjected in turn to analog-to-digital conversion (ADC). A difference of at least a pair of neighboring data out of the ADC with respect to each phase is determined. A maximum difference is determined, and the sampling clock with the phase corresponding to the maximum difference is thus generated.

Abstract: A method for playing multimedia data on a computer system. The computer system has a central processing unit (CPU) used to control operations of the computer system, a storage device used to retrieve the multimedia data, a bridge circuit electrically connected between the CPU and the storage device for coordinating data transmission between the CPU and the storage device, and an output device. The method includes providing the computer system with a playback controller electrically connected to the storage device and the output device, controlling the storage device to transmit the multimedia data to the playback controller without activating the bridge circuit, utilizing the playback controller to receive and process the multimedia data, and utilizing the playback controller to drive the output device to play the multimedia data.
