 MACROVISION Definition
We define MACROVISION |
MACROVISION - A method of copy protection that rapidly modulates colorburst signals and pulses the vertical blanking signal in order to make videotaped copies of protected materials unwatchable. Some older VCRs even have trouble viewing Macrovision-protected movies. DVD players typically have Macrovision circuits built-in to make copying of DVD movies impossible; however, some DVD players allow Macrovision to be disabled. |
