Abstract:
1. A method for reproducing digital data from a signal source, comprising the steps of: reading out recording control information supplied by said source, said recording control information indicating the playback mode of said source and including copy management information indicating whether copying of only digital data is inhibited or copying of both digital data and analog signals is inhibited; and performing a pre-set conversion operation on said digital data and/or an analog signal generated from said digital data, based on said recording control information; wherein said pre-set conversion operation for said analog signal includes a color burst inverting operation in which the phase of a front part of a color burst signal in said analog signal is inverted; wherein said color burst signal follows a pre-period burst signal inserted on the trailing side of a horizontal blanking pulse in said analog signal; said pre-period burst signal having the same phase as the inverted front part of the color burst signal.
