The present invention provides for an interface between two seemingly incompatible and different content protection systems. Accordingly, protected content may be transferred between the respective security kernels of a conditional access (CA) and digital rights management (DRM) systems, while maintaining security of the content and any associated protection information. The transfer and consumption of protected content and the associated content protection information may be achieved by temporarily or permanently binding the respective security kernels of the CA and DRM systems, transcribing content protection information, and potentially transcribing the content.
