Abstract: A method, apparatus and system enabling software access to navigational data in a decrypted media stream while protecting stream payloads. In one embodiment, a filter may route an encrypted content stream and associated information to a secure partition having a trusted computing component for decryption. Upon decryption, the trusted computing component may store the decrypted payload of the content in a secure storage location accessible to the trusted computing component. Thereafter, the decrypted navigational header information of the content may be used to navigate to the decrypted content via a trusted component such as a trusted rendering unit in the secure partition.
