Any design of a device that allows it to act against the intention of its owner constitutes a case of [[Right to own|eroded ownership]] over the device. | |||
A DRM technology is, by design, an artificial restriction of capabilities of a device, either in general or only for certain protected types of content. | A DRM technology is, by design, an artificial restriction of capabilities of a device, either in general or only for certain protected types of content. From a perspective of the rights holder (whose rights DRM protects), such restrictions need to be effective when the device or a copy of a creative work is in user's physical possession. And physical access inherently allows for many techniques of analysis and reverse engineering that may be used to devise a way to circumvent the restrictions. Therefore to be effective, a DRM technology needs to withstand the circumvention techniques available to consumers. This presents a significant engineering challenge, seemingly with no perfect solution, because solutions to date have failed or compromised various additional functions in different ways. | ||
For example, Netflix requires HDCP DRM for playback of its video content in advertised quality. And on multi-monitor systems HDCP only works if ''all'' connected monitors support it, not just the one that displays the video.<ref>{{Cite web |date=2024-02-24 |title=Netflix requires all monitors to be HDCP 2.2.
