1. A method comprising:

  • receiving from a transmitter a first transmission and deriving first received bits from the first transmission, the transmitter having (i) segmented a first content block from digital content according to a first block segmentation scheme, (ii) encoded the first content block to produce first channel bits therefrom, and (iii) caused all or a portion of the first channel bits to be communicated over radio frequency channels, thus resulting in the first transmission;

    after receiving said first transmission, receiving from the transmitter a second transmission and deriving second received bits from the second transmission, the transmitter having (i) segmented a second content block from the digital content according to a second block segmentation scheme, (ii) encoded the second content block to produce second channel bits therefrom, and (iii) caused all or a portion of the second channel bits to be communicated over radio frequency channels, thus resulting in the second transmission;

    combining into combined bits a subset of the first received bits and a subset of the second received bits; and

    providing to a decoder, together with the combined bits, those of the first received bits that were not combined,wherein the second block segmentation scheme differs from the first block segmentation scheme,wherein the first content block is not identical to the second content block,wherein a substring in the first content block is identical to a substring in the second content block, andwherein the first received bits that are combined into the combined bits relate to particular bits of the substring in the first content block, and the second received bits that are combined into the combined bits relate to the same particular bits of the substring in the second content block.
