HARDWARE ENFORCED OUTPUT SECURITY SETTINGS |
摘要 |
<p>Generally, aspects of this disclosure are directed to copy protection techniques. Areas in memory may be secured to establish a secure memory area in the memory that is not accessible by unauthorized clients. A request to decode video content stored in the secure memory area may be received. If the video content to be decoded is stored in the secure memory area, a first MMU associated with the hardware decoder may enforce a rule that the video content is to be decoded into one or more output buffers in the secure memory area. A request to display the decoded video content stored in the secure memory area may be received. If the decoded video content is stored in the secure memory area, a second MMU associated with a hardware display processor may enforce a rule that a secure link be established between the hardware display processor and an output device.</p> |
