Research and Implementation of Content Security Protection for Live Broadcasting Satellite Push Terminals
Because of the application characteristics that the live broadcasting satellite push terminal can't interact with the content protection front-end,this paper puts forward a content protection method that adapts to the live broadcasting satellite push terminal in the satellite broadcasting environment.It provides a secure content protection mechanism for the live broadcasting,recording,push,and other contents in the push terminal,so that the stored content and output content of the live broadcasting satellite push terminal is encrypted data,with the ability to receive and distribute secret keys.Under the premise of meeting the requirements of content security protection,the push terminal,mobile phones,PADs,and other clients connected to this machine can decrypt and play encrypted content,effectively ensuring the rights and interests of content providers and users in content security protection and use.
