DVD copy protection is a set of techniques to prevent unauthorized disruption and copying of DVDs. This is important for video creation because it protects you from piracy. The techniques ensure that the content on your DVD can only play on authorized devices and prevent people from making duplicate copies.
Content Scramble System (CSS)
This is among the earliest and most commonly applied ways to copy protected DVD services. It uses encryption to scramble the data on the DVD, rendering it unreadable unless you use a decryption key.
You can remove this protection using WinxX DVD Ripper Platinum, DVD Shrink, WinX DVD Copy Pro, and VLC.
Analog Protection System (APS)
Also referred to as Macrovision or Copyguard, this protection scheme adds pulses to the analog signals of the videos on the DVD. That negatively affects the AGC circuit of recording devices such that the images copied from the DVD are unwatchable and garbled.
You can remove this protection using WinX DVD Copy Pro or WinX DVD Ripper Platinum.
Regional coding
Encoding DVDs with a regional code restricts playback to certain geographical regions. This restriction matches region numbers to the configuration flags in DVD players. That helps content creators and producers to make and distribute content to different markets.
- Region 1– The US and Canada
- Region 2– Japan, South Africa, Europe, and the Middle East
- Region 3– Homg Kong and Southeast Asia
- Region 4– New Zealand, Australia, and Latin America
- Region 5– Eastern Europe, Russia, Africa (except South Africa), and India
- Region 6– China
- Region 7– For future use
- Region 8– Specific international venues like cruise ships and airplanes
- Region 0– All regions (Mostly used for ‘region-less’ or ‘region-free’ DVDs)
While you can bypass this system by changing the region on a DVD drive, there is a limit to the number of times you can do that.
