Patent attributes
The present invention provides for a method for reducing undesirable skipping during playback of a compact disc in a compact disc player. A lens system of the compact disc player reads audio data and subcode data from the compact disc. The subcode data includes Q channel bits and P channel bits. The actual time lapse of the compact disc playback is calculated from the Q channel bits and the P channel bits, while a target time lapse is calculated based on data received from a real-time clock. The difference between the two time lapse values is calculated, and if the differences is greater than a predetermined threshold, the lens system is repositioned to read the audio data from the compact disc corresponding to a predetermined time interval in advance of the current position of the lens system.
