Abstract
A digital data stream comprises alternating groups of information blocks and groups of parity blocks, each group of information blocks includes multiple information blocks and each group of parity blocks includes multiple parity blocks. An apparatus for receiving a digital data stream comprises a demodulator that receives and demodulates a digital data stream. An equalizer compensates for distortions in the digital data stream. A delay buffer generates a first stream of digital data representing the compensated digital data stream and a second stream of digital data representing a delayed version of the compensated digital data stream. A forward error correction block receives and processes the first and second streams of digital data from the delay buffer, and outputs an error corrected stream of digital data. A transport block receives and processes the error corrected stream from the forward error correction block for display.
