NAME

       drs232_ldpc - Horus SSTV reception using the codec2 library.

SYNOPSIS

       drs232_ldpc usage: InputOneBitPerChar OutputPacket [-v[v]]

DESCRIPTION

       Looks  for a unique word in series of soft decision symbols.  When found, deframes a RS232
       encoded frame of soft decision bit, LDPC decodes, and outputs a  frame  of  packed  bytes.
       Used for high bit rate Horus SSTV reception.

         Frame format:

           16  bytes  0x55  -  0xabcdef01 UW - 256 bytes of payload - 2 bytes CRC - 65 bytes LPDC
       Parity

         Each byte is encoded as a 10 bit RS232 serial word:

           0 LSB .... MSB 1

OPTIONS

       The first argument, InputOneSymbolPerFloat is the file name of a file with  Horus  encoded
       bits. If "-" is given the input is taken from stdin.

       The  second  argument,  OutputPackets  is the file name of a file to be created with modem
       sample data. If "-" is given the output is sent to stdout.

       The optional third argument, [-v] [-vv] set the verbosity of the output.
