Digital Transmission Content Protection ("DTCP") technology protects high-value digital motion pictures, television programs and audio against unauthorized interception and copying in the home and personal environment (e.g., between a digital set top box and gateway or between a personal computer and a digital TV).
There are two gstreamer filter elements that are used for content encryption/decryption.
A device enabled with DTCP determines whether it is connected to other devices that implement the DTCP protection technology. Content encoded for DTCP protection is encrypted and securely transmitted only to recording and display devices that implement DTCP. The content carries information indicating whether and to what extent the content may be copied.
All DTCP encryption and decryption uses common set of provided gstreamer elements, The gstreamer elements uses DTCP manager API. Each SoC provides binary DTCP encryption/decryption library to support the DTCP Manager API.
