The साल is 1983. In 1983, A San Francisco security company launched. It was called Macrovision. Macrovision was created for घर Video (Prerecorded Betamaxs, VHS, Laserdiscs, DVDs, and Blu-Rays) to prevent viewers from copying it. आप rented a Betamax tape from Blockbuster Video and आप made a copy on a blank Betamax tape but the screen suddenly scrambles. Well, That's the sign of Macrovision. They are there to prevent आप from copying it. Macrovision signal is on the tape itself. If आप want to know if the Betamax tape is copy-protected, Here is how! I have the oscilloscope. The signal will appear on the clear pulps part on the scope. It cause the screen to scramble and go crazy. On modern Betamax recorders and on DVD Recorders, It just stops the recording and gives आप the blue screen of death error that reads: "RECORDING ERROR!: This program is not allowed to be recorded!"
