Definition Edit

DivX is

the brand name of products created by DivX, Inc., including the DivX Codec, which has become popular due to its ability to compress lengthy video segments into small sizes while maintaining relatively high visual quality. It is one of several codecs, or digital data encoding and decoding programs, com­monly associated with ripping, where audio and video multimedia are transferred to a hard disk and transcoded. As a result, DivX has been a center of controversy because of its use in the reproduction and distribution of copyrighted DVDs.[1]

Overview Edit

[DivX], which is available over the Internet for nothing, with the investment of some time and effort, permits compression of the decrypted files to sizes that readily fit on a writeable CD-ROM. Copies of such CD-ROMs can be produced very cheaply and distributed as easily as other pirated intellectual property. While not everyone with Internet access now will find it convenient to send or receive DivX’d copies of pirated motion pictures over the Internet, the availability of high speed network connections in many businesses and institutions, and their growing availability in homes, make Internet and other network traffic in pirated copies a growing threat.”[2]

DivX is capable of compressing decrypted files constituting a feature length motion picture to approximately 650 MB at a compression ratio that involves little loss of quality. While the compressed sound and graphic files then must be synchronized, a tedious process that took plaintiffs’ expert between 10 and 20 hours, the task is entirely feasible. Indeed, having compared a store-bought DVD with portions of a copy compressed and synchronized with DivX (which often are referred to as ‘DivX’d’ motion pictures), the Court finds that the loss of quality, at least in some cases, is imperceptible or so nearly imperceptible as to be of no importance to ordinary consumers.”[3]
