     4.4 +This describes the program as shipped with cdrkit, a spinoff from the
     4.5 +cdrtools project. However, the cdrtools developers are no longer 
     4.6 +involved in the development of this spinoff and therefore shall not
     4.7 +be made responsible for any problem caused by it. Do not try to get 
     4.8 +support for this program by contacting the original authors.
     4.9 +
    4.10 +This is a small description for the Reed-Solomon library intended for
    4.11 +CD sector formatting.
    4.12 +
    4.13 +Basics:
    4.14 +It is assumed that you have a basic knowledge of cd sector formats.
    4.15 +
    4.16 +The library can handle three types of sector data:
    4.17 +  data sectors,
    4.18 +  audio sectors, and
    4.19 +  sub channel r-w sectors
    4.20 +
    4.21 +Currently only encoding is implemented. Decoding and optionally
    4.22 +error correction is planned for later.
    4.23 +
    4.24 +Stages:
    4.25 +
    4.26 +The process of sector formatting has several stages. Beginning with
    4.27 +a data sector (2048, 2324, or 2336 bytes) a sector of 2352 bytes is
    4.28 +built. This format can be read raw by SCSI MMC-2 and ATAPI drives and
    4.29 +is accepted by cd burners. The additions are an optionally 32 bit CRC
    4.30 +checksum and two layers of Reed-Solomon codes (called Reed-Solomon
    4.31 +Product Code RSPC).
    4.32 +This sector is then scrambled (exor'ed with a bitstream).
    4.33 +The result is called F1 frames. Afterwards even and odd bytes are
    4.34 +swapped, this is called F2 frames. The result is equivalent to an
    4.35 +audio sector and is treated as such by the cd burner.
    4.36 +So, if we wrote a series of sectors (F2 frames) into a CDR file and
    4.37 +later burned them as 'audio', they would turn up as perfect data sectors.
    4.38 +
    4.39 +So, now we are at the level of audio sectors. Audio sectors get their
    4.40 +own error correction data (called CIRC). Sector size goes up to 
    4.41 +3136 bytes (that is 4/3 times 2352 bytes). Furthermore different
    4.42 +words get delayed differently and swap positions. The result is ready
    4.43 +to be fed into the so-called EightFourteenModulator (when subchannels
    4.44 +have been added).
    4.45 +
    4.46 +Now, only sub channels are missing. While the p and q sub
    4.47 +channels have to be generated elsewhere, any supplied r-w subchannel
    4.48 +user data is protected by two levels of error correction
    4.49 +codes. This format is read by cd burners when burning cd+graphics.
    4.50 +The cdimage is a sequence of sectors, each containing audio data and
    4.51 +after that subchannel data.
    4.52 +Similar to audio sectors delaying and permutation of words
    4.53 +takes place. After that the cd burner would mix sub channel data with
    4.54 +the formatted audio sectors to feed the EFModulator.
    4.55 +
    4.56 +NOTE: Most of the described stages need not to be done in order to
    4.57 +prepare sectors for burning, since all cd burners do at least CIRC,
    4.58 +delaying and swaps. For data sectors they also do scrambling and f2
    4.59 +frame generation.
    4.60 +
    4.61 +Encoding routines:
    4.62 +
    4.63 +For data sectors
    4.64 + int do_encode_L2(unsigned char *inout, int sectortype, unsigned address);
    4.65 +
    4.66 + encodes data sectors. The returned data is __unscrambled__ and not in
    4.67 + F2-frame format.
    4.68 +
    4.69 +Parameters are:
    4.70 +  inout        pointer to an array of at least 2352 bytes.
    4.71 +  sectortype   One of the MODE_* constants from ecc.h. This defines
    4.72 +               how to format the sector.
    4.73 +  address      The logical address to be used in the header 
    4.74 +               (150 = 0:2.0 MSF).
    4.75 +
    4.76 +NOTE: the data portion has be to aligned properly for performance
    4.77 +reasons (see ecc.h for details). So, no moves are necessary here.
    4.78 +
    4.79 +Generating f2 frames to be used like audio sectors
    4.80 + int scramble_L2(unsigned char *inout)
    4.81 +
    4.82 + generates f2 frames in place from sectors generated by do_encode_L2().
    4.83 +
    4.84 +Parameters are:
    4.85 +  inout        pointer to an array of at least 2352 bytes.
    4.86 +
    4.87 +
    4.88 +
    4.89 +For sub channels
    4.90 + int do_encode_sub(unsigned char in[LSUB_RAW*PACKETS_PER_SUBCHANNELFRAME],
    4.91 +		unsigned char out[(LSUB_RAW+LSUB_Q+LSUB_P)*
    4.92 +					PACKETS_PER_SUBCHANNELFRAME],
    4.93 +		int delay1, int permute);
    4.94 +
    4.95 + repack user data and add error correction data. P and q subchannels
    4.96 +should be added later, since all bytes are in place then.
    4.97 +
    4.98 +Parameters are:
    4.99 +  in           pointer to an array of at least 72 bytes. It contains
   4.100 +               the user data for one frame.
   4.101 +  out          pointer to an array of at least 96 bytes. Here is
   4.102 +               output frame is placed.
   4.103 +  delay1       do low level delaying, when set to 1.
   4.104 +  permute      do low level permutations, when set to 1.
   4.105 +
   4.106 +NOTE: Probably both options need either to be set on (1) or off (0) together.
   4.107 +
   4.108 +There is more, but that is seldomly used.
   4.109 +
   4.110 +Tests:
   4.111 +The library is accompanied by small verify programs, that compare real
   4.112 +raw sectors with the formatted results. They are also intended as demo
   4.113 +applications (how to use the library). In order to be able to feed
   4.114 +real raw sectors into them, the package read2448 is recommended/needed.
   4.115 +You can only verify sector streams of one sector type, currently no mix.
