Abstract
A control system for a compact disc jukebox detects skips in the compact disc by reading an apparent elapsed time signal from the compact disc that is encoded on the compact disc. A timer is simultaneously started and outputs a real elapsed time signal. A comparison is made between the real elapsed time signal and the apparent elapsed time signal. If the difference between these two signals exceeds a predetermined amount of time, a skip is recorded. The detection of a skip may be recorded as to a particular selection on a particular CD, along with the time of the skip. Appropriate action may be taken in response to the recording of a skip, such as cancelling the selection or stopping the CD.
