Television transmission system using two stages of spead-spectrum processing

A spread-spectrum television receiver for receiving a transmission signal that was derived from a television production signal, said receiver comprising:

• a first direct sequence decoder processing a received television transmission signal to generate a set of hybrid signals;
• a quantizer quantizing members of a set of signals derived from said set of hybrid signals to produce a set of quantized signals;
• means for subtracting said set of quantized signals from said set of hybrid signals to produce a first set of analog signals;
• a second direct sequence decoder processing said set of first analog signals to generate a second set of analog signals;
• and
• means for reconstructing the television production signal from said second set of analog signals and said set of quantized signals.

A spread-spectrum television receiver for receiving a transmission signal that was derived from a television production signal, said receiver comprising:

• a direct sequence decoder processing a received television transmission signal to generate a set of hybrid signals;
• an N.times.N linear matrix means for removing crosstalk from said hybrid signals and thereby generate a set of derived signals, where N is the number of signals in the set of hybrid signals;
• a quantizer quantizing members of said set of derived signals to produce a set of quantized signals;
• means for subtracting said set of quantized signals from said set of hybrid signals to produce a set of analog signals;
• and
• means for reconstructing the television production signal from said set of analog signals and said set of quantized signals.
