Embodiment Construction

[0031] see figure 2 , is the method flowchart of the present invention, and concrete implementation steps are as follows:

[0032] S1. The mobile terminal acquires DRM-encrypted media content information and related decryption information, the most important thing is to obtain information such as a decryption key;

[0033] S2, the mobile terminal analyzes the obtained DRM media content information data packet, and can obtain the type of encrypted media content information by analyzing the packet header information, such as audio stream information, video stream information, or game software program code, etc.;

[0034] S3. Set the DRM media type registry in the mobile terminal to store the processing interface corresponding to the DRM media type; such as setting audio stream information and / or video stream information and / or game software is performed by a hardware processing chip processing, other media type information is processed by the corresponding software interface. ...
