HDCP 2.2 is frequently seen in the projector and display industry. What is HDCP 2.2?
HDCP refers to High-bandwidth Digital Content Protection technology developed by Intel. It can prevent copying of digital audio and video content.
The technology is widely applied to high-speed digital video interfaces, including HDMI and DVI. In order to ensure that the high-definition signal transmitted by HDMI or DVI will not be recorded illegally, HDCP technology appears. When users copy illegally, the technology will interfere and reduce the quality of the copied image, so as to protect the content.
HDCP 2.2 is a new version of HDCP, which was first released in 2012 and updated for different devices in later years. When users copy illegally, the technology will interfere and reduce the quality of the copied image, so as to protect the content.
Put it simply, HDCP 2.2 is a hardware-based copyright protection mechanism, and it requires the hardware, interfaces, and software to support this function.
Therefore, it is necessary to check whether the device interface supports HDCP 2.2 or not to ensure a smooth HD content play, especially for 4K UHD content. In addition, you’d better use premium HDMI cables to avoid play failure.
