ABSTRACT:
Disclosed is a compact disc apparatus having automatic start capabilities. The compact disc apparatus includes a digital signal processor for reading sectors that have a plurality of EFM frames, and the EFM frames contain at least a data component and a subcode component. Also included is a Q-subcode extractor for retrieving a Q-bit from each of the plurality of EFM frames being read by the digital signal processor. An auto-start unit is further included to analyze and process the retrieved Q-bits from each of the plurality of EFM frames, such that a determination is made as to whether a minute/second/frame derived from the retrieved Q-bits matches a desired start minute/second/frame location. Wherein the data being read from sectors by the digital signal processor starts transferring data to a memory beginning with the desired start minute/second/frame when the match is found by the auto-start unit.
