@chapter CD-TEXT from the User Viewpoint
CD-TEXT records attributes of disc and tracks on audio CD.
The attributes are grouped into blocks which represent particular languages.
Up to 8 blocks are possible.
There are 13 defined attribute categories, which are called Pack Types and are
identified by a single-byte code:
@table @kbd
@item 0x80
Title
@item 0x81
Performers
@item 0x82
Songwriters
@item 0x83
Composers
@item 0x84
Arrangers
@item 0x85
Message Area
@item 0x86
Disc Identification (text-and-binary)
@item 0x87
Genre Identification (text-and-binary)
@item 0x88
Table of Contents (binary)
@item 0x89
Second Table of Content information (binary; 0x8a to 0x8c are reserved.)
@item 0x8d
Closed Information
@item 0x8e
UPC/EAN code of the album and ISRC code of each track
@item 0x8f
binary: Size Information of the Block
@end table
Categories @kbd{0x86}, @kbd{0x87}, @kbd{0x88}, @kbd{0x89}, @kbd{0x8d}
apply to the whole disc.
Categories @kbd{0x80}, @kbd{0x81}, @kbd{0x82}, @kbd{0x83}, @kbd{0x84},
@kbd{0x85}, and @kbd{0x8e} have to also be attributed to each
track if they are present for the whole disc.
Category @kbd{0x8f} describes the overall content of a block and in part of all
other blocks.
The total size of a block's attribute set is restricted by the fact that
it has to be stored in at most 253 records with 12 bytes of
payload. These records are called Text Packs. A shortcut for repeated
identical track texts is provided, so that a text that is identical to
the one of the previous track occupies only 2 or 4 bytes.
@node Content Specification
@chapter Content Specificiation
Pack types @kbd{0x80} to @kbd{0x85} and @kbd{0x8e} contain 0-terminated
cleartext. If double-byte characters are used, then two 0-bytes
terminate the cleartext. The meaning of @kbd{0x80} to @kbd{0x85} should
be clear by above list. They are encoded according to the Character Code
of their block. Either as ISO-8859-1 single byte characters, or as 7-bit
ASCII single byte characters, or as MS-JIS double byte characters. More
info on @kbd{0x8e} is given below.
Pack type @kbd{0x86} (Disc Identification) is documented by Sony as
"Catalog Number: (use ASCII Code) Catalog Number of the album". So it is
not really binary but might be non-printable, and should contain only
bytes with bit7 = 0.
Pack type 0x87 contains 2 binary bytes, followed by 0-terminated cleartext.
The two binary bytes form a big-endian index to the following list.
@table @kbd
@item 0x0000
Not Used --- Sony prescribes to use this if no genre applies.

Sony documents the cleartext part as "Genre information that would supplement
the Genre Code, such as ``USA Rock music in the 60s\'''. Always ASCII encoded.
Pack type @kbd{0x88} records information from the CD's Table of Content, as of
READ PMA/TOC/ATIP Format 0010b (mmc5r03c.pdf, table 490 TOC Track Descriptor
Format, Q Sub-channel).
See below, Format of CD-TEXT packs, for more details about the content of
pack type @kbd{0x88}.
Pack type @kbd{0x89} is yet quite unclear. It might be a representation
of Playback Skip Interval, Mode-5 Q sub-channel, POINT 01 to 40
(mmc5r03.pdf 4.2.3.7.4). If so, then this seems not to apply to write
type SAO, because the CUE SHEET format offers no way to express Mode-5
Q. See below, Format of CD-TEXT packs, for an example of this pack
type.
Pack type @kbd{0x8d} is documented by Sony as "Closed Information: (use
8859-1 Code) Any information can be recorded on disc as
memorandum. Information in this field will not be read by CD TEXT
players available to the public." Always ISO-8859-1 encoded.
Pack type 0x8e is documented by Sony as ``UPC/EAN Code'' (POS Code) of
the album. This field typically consists of 13 characters." Always
ASCII encoded. It applies to tracks as "ISRC code [which] typically
consists of 12 characters" and is always ISO-8859-1 encoded. MMC calls
these information entities Media Catalog Number and ISRC. The catalog
number consists of 13 decimal digits. ISRC consists of 12 characters: 2
country code [0-9A-Z], 3 owner code [0-9A-Z], 2 year digits (00 to 99),
5 serial number digits (00000 to 99999).
Pack type 0x8f summarizes the whole list of text packs of a block.
See the next section for details.
@node CD-TEXT Packet Format
@chapter CD-TEXT Packet Format
The attributes are represented on CD as Text Packs in the sub-channel of
the Lead-in of the disc. The file @file{doc/cookbook.txt} of the
libburnia distribution ddescribe write the readily formatted CD-TEXT
pack array to CD, and how to read CD-TEXT packs from CD.
The format is explained in part in MMC-3 (mmc3r10g.pdf, Annex J)[2] and in
part by the documentation in Sony's cdtext.zip[3].
Each pack consists of a 4-byte header, 12 bytes of payload, and 2 bytes
of CRC.
The first byte of each pack tells the pack type. See above for a list of
types.
The second byte tells the track number to which the first text piece in
a pack is associated. Number 0 means the whole album. Higher numbers are
valid for types 0x80 to 0x85, and 0x8e. With these types, there should
be one text for the disc and one for each track. With types 0x88 and
0x89, the second byte bears a track number, too. With type 0x8f, the
second byte counts the record parts from 0 to 2.
The third byte is a sequential counter.
The fourth byte is the Block Number and Character Position Indicator.
It consists of three bit fields:
@table @var
@item bits 0-3
Character position. Either the number of characters which the current
text inherited from the previous pack, or 15 if the current
text started before the previous pack.
@item bits 4-6
Block Number (groups text packs in language blocks)
@item bit 7
Double Bytes Character Code (0= single byte characters)
@end table
The 12 payload bytes contain pieces of 0-terminated texts or binary data.
A text may span over several packs. Unused characters in a pack are used for
the next text of the same pack type. If no text of the same type follows,
then the remaining text bytes are set to 0.
The CRC algorithm uses divisor @kbd{0x11021}. The resulting 16-bit
residue of the polynomial division is zero extended in the upper bits
(xor-ed with @kbd{0xffff}) and written as big-endian number in bytes 16
and 17 of the pack.
The text packs are grouped in up to 8 blocks of at most 256 packs. Each block
is in charge for one language. Sequence numbers of each block are counted
separately. All packs of block 0 come before the packs of block 1.
The limitation of block number and sequence numbers imply that there are at
most 2048 text packs possible. (READ TOC/PMS/ATIP could retrieve 3640 packs,
as it is limited to 64 kB - 2.)
If a text of a track (pack types @kbd{0x80} to @kbd{0x85} and
@kbd{0x8e}) repeats identically for the next track, then it may be
represented by a TAB character (ASCII 9) for single byte texts,
resp. two TAB characters for double byte texts. (This should be used
because 256 * 12 bytes is few space for 99 tracks.)
The two binary bytes of pack type @kbd{0x87} are written to the first
@kbd{0x87} pack of a block. They may or may not be repeated at the start
of the follow-up packs of type @kbd{0x87}.
The first pack of type @kbd{0x88} in a block records in its payload bytes
as follows:
@table @var
@item 0
PMIN of POINT A1 = First Track Number
@item 1
PMIN of POINT A2 = Last Track Number
@item 2
unknown, 0 in Sony example
@item 3
PMIN of POINT A2 = Start position of Lead-Out
@item 4
PSEC of POINT A2 = Start position of Lead-Out
@item 5
PFRAME of POINT A2 = Start position of Lead-Out
@item 6 to 11
unknown, 0 in Sony example
@end table
The following packs record PMIN, PSEC, PFRAME of the POINTs between the
lowest track number (min 01h) and the highest track number (max 63h).
The payload of the last pack is padded by 0s.

Pack type @kbd{0x89} is yet quite unclear. Especially what the information shall
mean to the user of the CD. The time points in the Sony example are in the
time range of the tracks numbers that are given before the time points:
@smallexample
01 02:41:48 01 02:52:58

89 0d 2b 00 04 04 00 00 00 00 37 0d 1a 37 1f 32 0b 62
@end smallexample
The track numbers are stored in the track number byte of the packs. The
two time points are stored in byte 6 to 11 of the payload. Byte 0 of the
payload seems to be a sequential counter. Byte 1 always 4? Byte 2 to 5
always 0?
Pack type @kbd{0x8f} summarizes the whole list of text packs of a block.
So there is one group of three 0x8f packs per block.
Nevertheless each 0x8f group tells the highest sequence number and the
language code of all blocks.
The payload bytes of three @kbd{0x8f} packs form a 36-byte record.
The track number bytes of the three packs have the values 0, 1, 2.
@smallexample
Byte :
0 : Character code for pack types 0x80 to 0x85:
0x00 = ISO-8859-1
0x01 = 7 bit ASCII
0x80 = MS-JIS (japanese Kanji, double byte characters)
1 : Number of first track
2 : Number of last track
3 : libcdio source states: "cd-text information copyright byte"
Probably 3 means "copyrighted", 0 means "not copyrighted".
4 - 19 : Pack count of the various types 0x80 to 0x8f.
Byte number N tells the count of packs of type 0x80 + (N - 4).
I.e. the first byte in this field of 16 counts packs of type 0x80.
20 - 27 : Highest sequence byte number of blocks 0 to 7.
28 - 36 : Language code for blocks 0 to 7 (tech3264.pdf appendix 3)

@node Sony Text File Format (Input Sheet Version 0.7T)
@chapter Sony Text File Format (Input Sheet Version 0.7T)
This text file format provides comprehensive means to define the text
attributes of session and tracks for a single block. More than one
such file has to be read to form an attribute set with multiple blocks.
The information is given by text lines of the following form:
purpose specifier [whitespace] = [whitespace] content text
[whitespace] is zero or more ASCII 32 (space) or ASCII 9 (tab) characters.
The purpose specifier tells the meaning of the content text.
Empty content text does not cause a CD-TEXT attribute to be attached.
The following purpose specifiers apply to the session as a whole:
@smallexample
Specifier = Meaning
Text Code = Character code for pack type 0x8f
"ASCII", "8859"
Language Code = One of the language names for pack type 0x8f
Album Title = Content of pack type 0x80
Artist Name = Content of pack type 0x81
Songwriter = Content of pack type 0x82
Composer = Content of pack type 0x83
Arranger = Content of pack type 0x84
Album Message = Content of pack type 0x85
Catalog Number = Content of pack type 0x86
Genre Code = One of the genre names for pack type 0x87
Genre Information = Cleartext part of pack type 0x87
Closed Information = Content of pack type 0x8d
UPC / EAN = Content of pack type 0x8e
Text Data Copy Protection = Copyright value for pack type 0x8f
"ON" = 0x03, "OFF" = 0x00
First Track Number = The lowest track number used in the file
Last Track Number = The highest track number used in the file
@end smallexample
The following purpose specifiers apply to particular tracks:
@smallexample
Track NN Title = Content of pack type 0x80
Track NN Artist = Content of pack type 0x81
Track NN Songwriter = Content of pack type 0x82
Track NN Composer = Content of pack type 0x83
Track NN Arranger = Content of pack type 0x84
Track NN Message = Content of pack type 0x85
ISRC NN = Content of pack type 0x8e
@end smallexample
The following purpose specifiers have no effect on CD-TEXT:
@smallexample
Remarks = Comments with no influence on CD-TEXT
Disc Information NN = Supplementary information for use by record companies.
ISO-8859-1 encoded. NN ranges from 01 to 04.
Input Sheet Version = "0.7T"
@end smallexample
The following purpose specifiers accept byte values of the form 0xXY.
Text Code , Language Code , Genre Code , Text Data Copy Protection
E.g. to indicate MS-JIS character code (of which the exact name is unknown):
Text Code = 0x80
Genre Code is settable by 0xXY or 0xXYZT or 0xXY 0xZT.
Genre Code = 0x001b
Purpose specifiers which have the meaning "Content of pack type 0xXY"
may be replaced by the pack type codes. E.g.:
0x80 = Session content of pack type 0x80
Track 02 0x80 = Track content of pack type 0x80 for track 2.
Applicable are pack types 0x80 to 0x86, 0x8d, 0x8e.
Text Code may be specified only once. It gets speficied to "ISO-8850-1"
automatically as soon as content is defined which depends on the text
encoding of the block. I.e with pack types 0x80 to 0x85.
If a track attribute is set, but the corresponding session attribute is not
defined or defined with empty text, then the session attribute gets attached
as empty test. (Normally empty content is ignored.)

@chapter CDRWIN Cue Sheet with CD Text
A CDRWIN cue sheet file defines the track data source (@kbd{FILE}),
various text attributes (@kbd{CATALOG}, @kbd{TITLE}, @kbd{PERFORMER},
@kbd{SONGWRITER}, @kbd{ISRC}), track block types (@kbd{TRACK}), track
start addresses (@kbd{INDEX}). The rules for CDRWIN cue sheet files are
described at @url{http://digitalx.org/cue-sheet/syntax/} [4].
There are three more text attributes mentioned in the cdrecord manual
page for defining the corresponding CD-TEXT attributes: @kbd{ARRANGER},
@kbd{COMPOSER}, @kbd{MESSAGE}.
An Example of a CDRWIN cue sheet file:
