HDCP overview

The TFP513 provides high-bandwidth digital content protection (HDCP) by encrypting the transmitted active

pixel data stream sent to an HDCP receiver (like the TFP501). The HDCP algorithm is fully incorporated, and

only requires an external source of HDCP keys and a software driver to implement an HDCP host.

The HDCP technology requires adherence to the HDCP license’s compliance (available from

www.digital-cp.com) and robustness rules. These rules require that HDCP implementation both protect the

confidentiality of keys and other values from compromise as well as deliver the desired protection for high-value

video content. The TFP513 provides a complete, easily implemented solution to these requirements.
