1. An apparatus for processing a first and a second stream of digital data, each stream of digital data including data blocks, the apparatus comprising:
- a stagger multiplexer that processes the first and the second streams of digital data concurrently to output a combined stream of digital data; and
a stagger demultiplexer that processes the combined stream of digital data to output a first and a second stream of extrinsic digital data, wherein data blocks of the first stream of extrinsic digital data include alternating groups of information blocks and zero blocks and data blocks of the second stream of extrinsic digital data include alternating groups of parity blocks and zero blocks.
