| // * Concrete key system |
| // A key system string that can be instantiated, such as |
| // via the MediaKeys constructor. Examples include "org.w3.clearkey" and |
| // "com.widevine.alpha". |
| // * Abstract key system |
| // A key system string that cannot be instantiated like a concrete key system |
| // but is otherwise useful, such as in discovery using isTypeSupported(). |
| // * Parent key system |
| // A key system string that is one level up from the child key system. It may |
| // be an abstract key system. |
| // As an example, "com.example" is the parent of "com.example.foo". |
