What is HDCP?
HDCP is “High-bandwidth Digital Copy Protection.” HDCP is a form of digital copy protection and was developed to protect digital audio and video content as it travels across digital connections. Contractual requirements from content providers require DISH Network and all other cable and satellite providers to activate HDCP on your receiver. With these new requirements, your TV and your digital video connection to your TV must be HDCP-capable in order to view Pay-Per-View and Video On demand content through a digital connection.
“HDCP” was developed to protect the intellectual property of software/movie studios and distributors. It stands for ‘High-bandwidth Digital Content Protection’), and is a digital code buried within the bitstream which is output from the digital source. This prevents unauthorised copying of protected materials, much like Macrovision did for analogue recordings. Only since the introduction of this standard have hardware manufacturers been allowed to offer DVI-D or HDMI outputs on their DVD players, High Definition TV tuners etc. Any device which bears the label “HDCP” simply means that it is complaint with the requirements. It does not change the output signal in terms of quality, it only refers to the additional code which it contains. All HDMI products are HDCP compliant and most DVI products are. Products which are not HDCP compliant will not work with products which are. A common area where this problem is encountered is from a DVI-D video card to HDMI display.
High Bandwidth Digital Content Protection System (HDCP) HDCP is a specification developed by Intel Corporation to protect digital entertainment content across the DVI and HDMI interface. The HDCP specification provides a transparent method for transmitting and receiving secure digital entertainment content to HDCP enabled DVI and HDMI digital displays.
What does HDCP mean? What does HDCP mean? HDCP is shorthand for high band width digital-content protection. This is a specification that was developed by Intel for the protection of digital entertainment content that uses the DVI interface. HDCP provides encryption for the transmission of digital content between the video source, or transmitter, like a computer, a DVD player, or a set-top box, and the digital display, or the receiver, like a monitor, a television or a projector. HDCP was not designed to prevent the copying or the recording of digital content, but to protect the integrity of the content as it is being transmitted. To implement HDCP, a license is required that is obtainable from the Digital Content Protection, LLC, which will then issue a set of unique secret device keys to all the authorized devices. During the authentication, the receiver will only accept the content once it demonstrates a knowledge of the secret keys. Plus, to prevent any eavesdropping and stealing of
