Patent ID: 8020080

Claim:
A receive apparatus comprising: first and second receive channels configured to receive first and second distinct modulated and coded signals, the first receive channel comprising a first demodulator capable of receiving the first modulated and coded signal and of providing a first coded signal to a first decoding system and the second receive channel comprising a second demodulator coupled to a second decoding system, the first decoding system being capable of receiving the first coded signal and of providing a first decoded signal comprising portions considered correct; a delay device having an input connected to the input or the output of the first demodulator; a multiplexer with two inputs and one output, a first input of the multiplexer being coupled to the delay device and a second input of the multiplexer coupled to the output of the second demodulator or configured to receive a second modulated and coded signal, the output of the multiplexer being coupled to the input of the second demodulator or the input of the second decoding system; a control device comprising means for generating a corrected signal from signals provided by the first decoding system and means for controlling the second decoding system and/or the second demodulator; and a circuit capable of providing a selection signal controlling the multiplexer and the control device, wherein, when the selection signal is positioned to let through the signal provided by the delay device, the second decoding system and/or the second demodulator are capable of providing a second decoded signal from the first coded signal or the first modulated and coded signal and from the portions considered correct of the first decoded signal.
