analog hole

A loophole for evading the copy protection applied to digital music and movies. Audio/video equipment typically has both analog and digital outputs, and most analog signals are not subject to copy protection. Therefore, the analog outputs can be used to re-record the content without restriction.

For example, the output of the headphone jack on a music player and the output of the analog composite or component video jacks on a Blu-ray or DVD player can be recorded free of digital rights management (see DRM). See analog sunset, component video and composite video.
