COPY CONTROL APPARATUS AND METHOD OF VIDEO SIGNAL

摘要

PURPOSE: A copy control apparatus and method of a video signal is to detect a copy protection signal and to interrupt recording operation, informing a user that a record carrier to be copied is a copy protected one, when the video signal with the copy protection signal inserted therein is recorded. CONSTITUTION: A copy control apparatus comprises: a video signal processing unit(203) for separating a composite synchronization signal from a video input signal to be recorded and for performing modulation and demodulation of the video signal; a determination unit(204) of presence/absence of a copy protection signal for receiving the composite synchronization signal and for determining if the copy protection signal is included therein; and a control unit(205) for generating a copy protection control signal to interrupt a recording execution mode, when the copy protection signal is determined to be included. Further, a copy control method comprise the steps of: determining if a copy command is inputted; comparing a time(T1) read from a timer with a threshold value(T0); determining whether the copy protection signal is detected from the video signal to be recorded, if the T1 is T0 or more; and interrupting a copy mode when the copy protection signal is detected.
