Abstract:
An intelligent transceiver comprising:a bus; a modular front-end block coupled to said bus, said modular front-end block comprising: an in-band tuner adapted to receive from a digital broadcast system in-band digital signals comprising audio content and video content; and a second tuner for receiving digital signals via the Internet, wherein digital signals received via said second tuner comprise a scramble key used in descrambling a scrambled digital signal; a modular conditional access block coupled to said bus, said modular conditional access block adapted to descramble said scrambled digital signal; and a plurality of other modular functional blocks coupled to said bus, said other modular functional blocks comprising a central processing unit and functional units adapted to decode said audio and video content and to generate an output audio/video signal for rendering on a display device; wherein said in-band tuner and said second tuner communicate with said other modular functional blocks via said bus using a shared bus interface and bypassing said modular conditional access block.
