Abstract
Disclosed herein are representative embodiments of tools and techniques for facilitating decoding of protected media information using a secure operating system. According to one exemplary technique, encoded media information that is encrypted is received at a secure process of a secure operating system of a computing system. At least a portion of the encoded media information that is encrypted is decrypted in the secure process. The portion of the encoded media information includes header information. Additionally, the header information is sent from the secure operating system to a software decoder for control of decoding hardware. The software decoder is included in a process for an application. Also, the decoding hardware is securely provided access to the encoded media information for decoding of the encoded media information to produce decoded media information.
