/**
|
||
|
|
* IMediaCasService is the main entry point for interacting with a vendor's
|
||
|
|
* cas HAL to create cas and descrambler plugin instances. A cas plugin instance
|
||
|
|
* opens cas sessions which are used to obtain keys for a descrambler session,
|
||
|
|
* which can in turn be used to descramble protected video content.
|
||
|
|
*
|
||
|
|
* The 1.2 must always create 1.2 ICas interfaces, which are
|
||
|
|
* returned via the 1.1 createPluginExt method.
|
||
|
|
*
|
||
|
|
* To use 1.2 features the caller must cast the returned interface to a
|
||
|
|
* 1.2 HAL, using V1_2::ICas::castFrom().
