Silicon Image at the Forefront of HDCP 2.2 Compatible Technologies

Oct 17, 2014
 

High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection and Digital Restrictions Management developed by Intel Corporation to prevent copying of digital audio and video content as it travels across connections, including DisplayPort (DP), Digital Visual Interface (DVI), and High-Definition Multimedia Interface (HDMI). The system is meant to protect HDCP-encrypted content from being played or copied on unauthorized devices. Before sending data, a transmitting device such as a set-top box, DVD or Blu-ray Disc player, or computer video card checks that the receiver, such as a TV or digital projector, is authorized to receive the content. If it is, the transmitter encrypts the data as it is sent to the receiver. 

In September 2010, a master key that allowed for the generation of valid device keys under HDCP 2.0 and 2.1 was released to the public, rendering the key revocation, or receiver checking, feature of HDCP useless. This created the need for a new, secure HDCP standard: version 2.2. HDCP 2.2 will allow video content creators to release data, including 4K UltraHD content, with the confidence that their work will be protected. 

Silicon Image is an industry leader in the HDCP specification, and is staying at the forefront of technology by creating products that will be able to receive 4K content under the new 2.2 standard, along with products that will bridge the gap between HDCP 2.2 and HDCP 1.x.
