Abstract:
A method for controlling remote reproduction of an information-stored medium in a reproduction apparatus that includes a reproduction unit for reproducing the information-stored medium in which an identification (ID) information is recorded in constant angular velocity (CAV) drive mode, and an external device for communicating with a remote server for playback permission of said information-stored medium, the method comprising the steps of:transmitting CAV rotating speed information for reproduction of said ID information from said external device to said reproduction unit; and comparing information on an actual rotation speed of the information-stored medium rotating under servo-control in the reproduction unit with the transmitted CAV rotation speed information, and reading out said ID information when the difference of the comparison result falls within an allowable predetermined difference range, wherein the allowable predetermined difference range is determined based on the number of ID information read-out trials.
