High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection developed by Intel Corporation to prevent the copying of digital audio and video content as it travels across digital connections including HDMI.

Any device associated with this type of DRM will often have an HDCP transmitter chip. It uses the Image Constraint Token (ICT). This protocol flag can cause the downsampling of high-definition video content on Blu-ray to DVD quality video and not be able to enjoy high-definition video from such discs. It faced several breaches including a 2010 master key leak, making HDCP useless.
