Modular broadcast receiver system and method

A signal receiving system comprising:na receiver configured to receive a scrambled signal corresponding to a first broadcasting provider or a second broadcasting provider;a filter to extract information of a desired program from the scrambled signal to generate an extracted scrambled signal, the filter extracting only packets for the desired program from a transport stream, in which the desired program is included, by referring to a packet ID;a first descrambler configured to descramble an extracted scrambled signal corresponding to the first broadcasting provider;a second descrambler configured to descramble an extracted scrambled signal corresponding to the second broadcasting provider; anda selector configured to select one of first descrambler and second descrambler,wherein the receiver and filter are controlled by a first microprocessor unit, and the filter is coupled to a first digital interface, andwherein the system further comprises a second digital interface for receiving a descrambled signal generated by either of the first descrambler or second descrambler, a demultiplexer for demultiplexing a signal received from the second digital interface, and a second microprocessor unit for controlling the demultiplexer.

A signal receiving method comprising:nreceiving a scrambled signal corresponding to a first broadcasting provider or a second broadcasting provider by a receiver;extracting information of a desired program from the scrambled signal to generate an extracted scrambled signal, the information of the desired program being extracted from a transport stream, in which the desired program is included, by referring to a packet ID; andselecting one of first descrambler and second descrambler by a selector,wherein the first descrambler descrambles the extracted scrambled signal corresponding to the first broadcasting provider and the second descrambler descrambles the extracted scrambled signal corresponding to the second broadcasting signal,wherein the steps of receiving and extracting are controlled by a first microprocessor unit, and the extracted scrambled signal is coupled to a first digital interface, andwherein the a descrambled signal generated by either of the first descrambler or second descrambler is coupled to a second digital interface, a demultiplexer demultiplexes a signal received from the second digital interface, and the demultiplexer is controlled by a second microprocessor unit.
