Bit error detection and recovery for X2D MMR coded bitstreams

This paper proposes a bit error recovery method for Extended 2 Dimensional MMR coded bitstreams. When an error occurs in an MMR coded bitstream, the bitstream cannot be decoded correctly after the error point. To prevent losing valid information after an error, we developed an error recovery system that detects bit errors and applies bit-inversion to correct the errors. In case the bit-inversion cannot correct the error, the system applies new algorithms that utilize syntactical structure information of the coded bitstream to recover nearly all the data.
