%description
libcorrect is a library for Forward Error Correction. By using libcorrect,
extra redundancy can be encoded into a packet of data and then be sent
across a lossy channel. When the packet is received, it can be decoded to
recover the original, pre-encoded data.

%description -n libcorrect%{sover}
libcorrect is a library for Forward Error Correction. By using libcorrect,
extra redundancy can be encoded into a packet of data and then be sent
across a lossy channel. When the packet is received, it can be decoded to
recover the original, pre-encoded data.

libcorrect accomplishes this task with two algorithms, Convolutional codes
and Reed-Solomon. Convolutional codes are robust to a constant background
noise, while Reed-Solomon error correction is effective at dealing with
noise that occurs in bursts. These algorithms have played an important role
in telecommunications. libcorrect uses a Viterbi algorithm decoder to decode
convolutional codes.
