What is copy protection?

Copy protection includes technological barriers that either prevent electronic content from copying or making a task more difficult. The techniques used have evolved together with technology, especially digital content growth. Some systems have caused controversy because users believe that they unfairly reduce what can be considered legitimate use. It was a system used to prevent video cassette copying. It used that some of the rows used to transmit the TV signal do not appear on the screen itself. By inserting a specially coded signal into these lines, protection meant that any copies had poorly distorted images. Most DVD recorders are set to stop recording if they detect the Makrovision signal from the video recorder connected to them.

When the videotapes were replaced by DVD, the threat of illegal copying increased. This is because the content is stored digitally, the macro can be made an exact copy without losing quality. It is also possible to copy the digital obsAh as fast as the computer can process information rather than have to play content in real time. The DVD branch uses a form of protection against a copy known as CSS, which is an abbreviation for the Scramble Content system. This locks the contents, so it can only be played using keys that can be read by a DVD player, but are stored in a disk that is not copied to a computer.

While there are several computer programs that can overcome CSS restrictions, they are illegal in many countries. In the United States, they are covered by the Act on Copyright for the Digital Millennium. This prohibits any software that bypasses the protection of digital copy. Many such programs are available from a website based in countries with more free laws on copyright. The actual networks tried to launch what charged as a legal component of copying DVDs in 2008, although since April 2009 it has been banned by a courtUntil the Civil Court.

Copy protection itself is not so popular in digital sound content, although some commercial CDs include technology to prevent copying. Downloading digital rights is the Chief Anti-Piration technique for music files for download. This encodes the relevant files to play only on a specific computer or portable device, although some systems allow the composition to play on a fixed number of devices. This system has caused controversy because some users believe that as soon as they buy digital music files, they should be able to play them anywhere, as with CDs. There are also claims that digital rights management unfairly limits listeners to the use of specific audio programs or music players produced by specific manufacturers.

with computer software, copy protection usually does not include literally preventing files from copying files. There are a number of techniques deposited to stop the used copyV version. In some cases, this may include the delivery of a reserved user name and a license number to legitimate customers. Other techniques include the user to activate the software before it works fully, usually by connecting to the manufacturer via the Internet so that the file can be checked and verified as legitimate.
