All Known Subinterfaces:

ICencDRMInfo2
```
public interface ICencDRMInfo
```
Interface for Common Encryption (CENC) DRM information classes. DRM system-specific metadata can be attached to a stream's CENC data to indicate that a stream or a media segment within that stream is protected by the particular DRM system, and may be authorized and decrypted by a player client using the provided DRM system metadata. The metadata provided by classes implementing ICencDRMInfo is inserted into a stream's manifest and/or fragment files. CENC DRM support is in accordance with the Common Encryption standard (ISO/IEC 23001-7).

    license acquisition URL string
  - setURL
```
void setURL(String url)
```
    Sets the license acquisition URL.
    Example: "http://www.mycompany.com/sdrm/rightsmanager.asmx"
    
    Parameters:
    
    url - license acquisition URL string
  - getNameSpaces
```
String getNameSpaces()
```
    Returns a string defining zero or more custom xml name space strings to be inserted into an xml-formatted manifest, such as an MPEG-DASH MPD.
    Example: xmlns:sdrma="urn:mycompany:superdrm:a" xmlns:sdrmb="urn:mycompany:superdrm:b"
    
    Returns:
    
    zero or more xml name space strings separate by spaces, with a "" or 'null' return indicating no custom namespaces
  - getMPEGDashCPSubElements
```
String getMPEGDashCPSubElements(boolean keyRotation)
```
    Returns a string defining zero or more custom xml elements to be inserted as sub-elements to the ContentProtection element that defines the DRM system in an MPEG-DASH MPD. The element would typically contain Base64-encoded system-specific metadata.
    Example: <sdrma:hdr></sdrma:hdr>
    The resulting ContentProtection element would look something like:
    <ContentProtection schemeIdUri="urn:uuid:12345678-1234-1234-1234-123456789012" value="SuperDRM"> <sdrma:hdr></sdrma:hdr> </ContentProtection>
    
    Parameters:
    
    keyRotation - indicates whether key rotation is enabled
    
    Returns:
    
    string defining the MPEG-DASH ContentProtection sub-elements
  - getSystemName
```
String getSystemName()
```
    Returns a string defining the DRM system name. This string would be used as the value of the value attribute in the ContentProtection element that defines the DRM system in an MPEG-DASH MPD.
    Example: "SuperDRM"
    The resulting ContentProtection element in an MPEG-DASH MPD would look something like:
    <ContentProtection schemeIdUri="urn:uuid:12345678-1234-1234-1234-123456789012" value="SuperDRM"> <sdrma:hdr></sdrma:hdr> </ContentProtection>
    
    Returns:
    
    string defining the DRM system name
