What is HDCP?
Digital content protection with high bandwidth (HDCP) is a form of Digital Rights (DRM) created by Intel. It has been designed to protect the transmission of high quality digital content from a video source such as a computer, a satellite TV receiver or a DVD player on a receiver such as a TV screen or a computer monitor. Specifically, technology has tried to achieve some copyright protection in sound and video content, such as movies, videos and television. Although not all computers are compatible with HDCP, some computer manufacturers have turned to HDCP to ensure that additional protective measures are introduced. For example, Windows® Vista® computers usually have HDCP specification. HDCP specifications can be found in some digital video interfaces (DVIS) - the video interface standard found in display devices such as a flat panel LCD. HDCP can also be found in many monitors, game consoles, players with blue PAmushes who have a high -resolution multimedia interface (HDMI), as well as monitors and systems of domestic cinema that have the DisplayPort interface.
HDCP works basically as follows. When a DVD or blue beam is placed on a computer or DVD player or when a satellite receiver is on, the transmitter immediately checks the transmitter to ensure that the receiver is licensed with HDCP keys. If the machine does not have the correct license, it will not be allowed to receive and display the HDCP protected material. If the correct HDCP controls are introduced, the computer or TV screen DVD or audio and video content is displayed on this monitor.
HDCP license is checked for during the reconnaissance session - not just the beginning of transmission. In general, HDCP controls allow friendly exchange between transmitter and receiver, while blocking other receivers in capturing, theft or otherwise viewing the content.
HDCP license can result in a fine and your ability to view the content of protected HDCP may be canceled. In 2001, a group of scientists claims to have created a hack for HDCP and bypass encryption protection. Nevertheless, the Federal Communication Commission approved the protective technology in 2004.
