Patent ID: 7065211

Claim:
A method for reproducing a video signal, comprising the steps of: receiving a video signal with appended copy management information at a reproducing device via a satellite communication link; said copy management information including an indicator of whether copying of only digital data is inhibited or copying of both digital data and analog signals is inhibited; detecting said copy management information that has been appended to the video signal; providing a copy permission indicator in the received video signal by generating a protect code signal based on said copy management information, said protect code signal having plural coded bits and being operable to indicate a generation limitation on copying of the video signal, and arraying said protect code signal at a pre-set position in the video signal; and performing a pre-set conversion operation on said digital data and/or an analog signal generated from said digital data, based on said copy management 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.
