Abstract: PURPOSE: A conditional access system of a digital cable broadcasting system and a receiving system and method using the conditional access system are provided to conditionally receive broadcast using DVS-167 or DOCSIS as an out-of-band channel transmission method. CONSTITUTION: A conditional access system includes a demultiplexer(322), an out-of-band channel signal processor(323), a conditional access processor(325), and a multiplexer(321). The demultiplexer receives broadcast data transmitted through an in-band channel and an ECM(Entitlement Control Message) including a control word from a subscriber receiver(310) and demultiplexes the broadcast data and the ECM. The out-of-band channel signal processor receives an EMM(Entitlement Management Message) transmitted through an out-of-band channel from the subscriber receiver and processes the EMM. The conditional access processor descrambles scrambled broadcast data using the EMC and EMM. The multiplexer multiplexes the descrambled broadcast data and provides the multiplexed broadcast data to the subscriber receiver.

Abstract: PURPOSE: A system and method for descrambling transport stream data are provided to descramble TS packet data inputted to a point of deployment module. CONSTITUTION: A system for descrambling transport stream data includes a transport stream packet input unit(20), a descrambling controller(30), and a descrambler(50). The transport stream packet input unit judges whether or not the transport stream data is descrambled using a header value of the TS packet data and outputs the judged result and TS packet data. The descrambling controller outputs a control signal to the TS packet input unit to allow the TS packet input unit to read the TS packet data and outputs a scrambling judgement signal according to the judged result. The descrambler judges whether or not the TS packet data is scrambled according to the scrambling judgement signal to vary descrambling process.
