Patent ID: 8189689

Claim:
A receiver receiving a transport stream to demodulate the transport stream into a final output stream, the transport stream comprising a plurality of symbols at least one of which carrying at least one program clock reference (PCR) value, the final output stream comprising a plurality of demodulated symbols each comprising a plurality of packets, the receiver comprising: a Reed-Solomon decoder configured to decode the transport stream to generate a MPEG (Motion Pictures Expert Group) packet; a MPEG memory configured to store the MPEG packet; a descrambler; and a transmission parameter signal decoder configured to extract information containing transmission parameters related to an applied modulation from the transport stream, and provide the transmission parameters to the descrambler; wherein the descrambler is configured to: read the MPEG packet from the MPEG memory with a reading rate of the descrambler that is dynamically decreased according to the transmission parameters, and descramble the MPEG packet into one of the packets of the demodulated symbols of the final transport stream, whereby bursts of the packets of the demodulated symbols of the final output stream are reduced.
