The invention discloses a
system and a method for multi-condition receiving and support on the set-top box; the method is used in the set-top box
system formed by an interlayer, a
software development kit module and a
portable application programming interface module. The interlayer comprises a video and audio control object, a
service information engine object and a condition receiving object interface. The method comprises two concurrent processes of a background
processing of the
authorization management information and a radio
station processing. The multi-condition receiving and
support system used in the set-top box of the invention comprises an interlayer and a
portable application programming interface module, and the interlayer further comprises: a video and audio control object and a condition receiving object interface, and a
service information engine object used to acquire the related control information of the condition receiving according to analyzing the
service information form; the
portable application programming interface module can be used to support the
broadcasting of the video and audio, the receiving of the service information and the condition receiving data, the transmission of the
smart card data, the usage of the descrambling device and the invoke of the
operating system.
