System and method for copy protection for digital signals |
摘要 |
Embodiments of the present invention provide for the copy protection of distributed material after conditional access is applied, regardless of where the material is distributed. The solutions described provide the advantage of being sufficiently simple in implementation to qualify as "curb high" solutions. "Curb high" solutions provide a range of security from minimal security to a high level of security while requiring relatively fewer system resources to implement than prior approaches. |
