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
