Abstract:
1. A method for staggercasting that is operated by a transmitter, the method comprising the steps of: encoding a first signal representing content for generating a first encoded signal comprising successive independent decoding segments; encoding a second signal representing the content for generating a second encoded signal comprising successive independent decoding segments respectively corresponding to the independent decoding segments of the first encoded signal; and wherein the encoding used for said second signal is different from the encoding used for said first signal, delaying the first encoded signal with respect to the second encoded signal; generating a composite signal comprising the delayed first encoded signal and the second encoded signal; and channel encoding the composite signal such that the portion of the composite signal representing the first encoded signal is channel encoded differently from the portion of the composite signal representing the second encoded signal, wherein each independent decoding segment has an associated time duration; and in the delaying step, the first encoded signal is delayed by the associated time duration with respect to the second encoded signal.
