What is HDCP?

High-Bandwidth Digital-Content Protection (HDCP) is a
device used for protecting the original content while
transferring the content from a computer, satellite television receiver, or DVD player to
the television screen or computer monitor. It is a form of Digital
Right Management developed by Intel Corporation to control digital audio and video content
while transferring across Digital Visual Interface (DVI) or High-Definition Multimedia Interface
(HDMI) connections. For using HDCP, a license is essential provided by Digital Content Protection,
LLC, a subsidiary of Intel.
The DRM device exists in the computer, DVD player or
Set Top Box, that keep control the digital audio and video content and ask for
the license, if HDCP license is present, it allows the content to display on the
screen. Whenever power is on or the system has been on, the content immediately
checks the existence of HDCP license. HDCP also control over the graphical images
while traveling over high bandwidths and keep it as safe and unchanged as
original images without any distortion or cross contamination, on the other hand
it also restricts to DAT quality (analog quality) on digital audio output. HDCP
licensees restricted to make copies of the content.
Nowadays the trends of wireless
technology is being popular and with WI-FI technology, the value
of HDCP has been increased as it protects the
information. So more and more computer manufacturers are making computer systems
with HDCP code.
