The Macrovision Analog Protection System (APS), also known as Copyguard by some people, is a videocassette and videodisc copy protection system originally developed by Macrovision Corporation. The system was developed to prevent bootlegging of original videocassettes and DVDs.
System History
The Analog Protection System was originally introduced in 1985 with the home video release of the 1984 film The Cotton Club by Embassy Home Entertainment. It was intended to replace the StopCopy protection system first introduced in 1978. By 1990, most of the major film distributors were using the APS system for their releases, with the main holdout coming from RCA/Columbia Pictures Home Video.
