@chapter CD Text Categories (Pack Types)
CD Text provides a way to give disk and track information in an audio
CD. This information is used, for example, in CD players to
provide information about the audio CD.
The information is grouped into blocks, each one in a particular
language. Up to 8 languages (or blocks) can be stored.
Within a block, there are 13 categories of information, called @emph{Pack
Types}.
The CD Text categories are identified by a single-byte code.
@xref{table:categories}.

Some additional information regarding specific pack types:
@itemize
@item Pack Types @kbd{0x8a} to @kbd{0x8c} are reserved.
@item Pack Types @kbd{0x86},@kbd{0x87}, @kbd{0x88}, @kbd{0x89}, @kbd{0x8d} apply to the whole
disc, and can not be attached to individual tracks.
@item Pack Types @kbd{0x80}, @kbd{0x81}, @kbd{0x82}, @kbd{0x83}, @kbd{0x84},
@kbd{0x85}, and @kbd{0x8e} have to be attributed to each
track if they are present for the whole disc.
@item Pack Type @kbd{0x8f} describes the overall content of a block and in part of all other blocks.
@end itemize
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 @emph{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 Text Packs
@chapter Text Packs
Pack types @kbd{0x80} to @kbd{0x85} and @kbd{0x8e} contain a
NUL-termintated string. If double-byte characters are used, then two
zero bytes terminate the text. Pack types @kbd{0x80} (Title) to
@kbd{0x85} (Message Area) are encoded according to their block's
Character Code. This could be either as ISO-8859-1 single byte
characters, as 7-bit ASCII single byte characters, or as MS-JIS double
byte characters. Pack type @kbd{0x8e} (album/track code) is described
below.
For pack type @kbd{0x86} (Disc Identification) here is how Sony describes this:
@quotation
Catalog Number: (use ASCII Code) Catalog Number of the album
@end quotation
So it is not really binary but might be non-printable, and should contain only
bytes with bit 7 set to zero.
Pack type @kbd{0x87} (Genre Identification) contains 2 binary bytes
followed by NUL-byte terminated text. Categories associated with
their Big-endian 16-bit value are listed in @ref{table:genres}.

@end float
Sony documents report that this field contains:
@quotation
Genre information that would supplement
the Genre Code, such as ``USA Rock music in the 60's''.
@end quotation
This information is always ASCII encoded.
Pack type @kbd{0x88} records information from the CD's Table of
Contents, as of READ PMA/TOC/ATIP Format 0010b (mmc5r03c.pdf, table
490 TOC Track Descriptor Format, Q Sub-channel).
Pack type @kbd{0x89} (Second Table of Contents) is not yet clear. 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 @ref{TOC Pack Types} for more details about the content of pack
types @kbd{0x88} and @kbd{0x89}.
Pack type @kbd{0x8d} Sony documents says:
@quotation
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.
@end quotation
It is always ISO-8859-1 encoded.
Pack type @kbd{0x8e} is documented by Sony as:
@quotation
UPC/EAN Code (POS Code) of the
album. This field typically consists of 13 characters.
@end quotation
This is 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 @kbd{0x8f} summarizes the whole list of text packs of a block.
See the next section for details.
@node Text Pack Contents
@chapter Text Pack Contents
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
@url{http://libburnia-project.org/,libburnia} distribution describes how
to write the CD Text pack array to CD, and how to read CD Text packs
from CD.
The format is explained in part in MMC-3 (@ref{mmc3r10g.pdf,,
mmc3r10g.pdf Annex J}), and in part by the documentation in Sony's
@ref{cdtext.zip,,cdtext.zip}.
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 @kbd{0x80} to @kbd{0x85}, and @kbd{0x8e}. With these
types, there should be one text for the disc and one for each track.
With types @kbd{0x88} and @kbd{0x89}, the second byte bears a track
number, too. With type @kbd{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 @dfn
@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
Is Double Byte Character? Is 0 if single byte characters, 1 if double-byte
characters.
@end table
The 12 payload bytes contain pieces of ASCII NUL- or
@code{\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}.
@node TOC Pack Types
@chapter TOC Pack Types
The first pack of type @kbd{0x88} (Table of Contents) records in its
payload bytes as follows:
@smallexample
0 : PMIN of POINT A1 = First Track Number
1 : PMIN of POINT A2 = Last Track Number
2 : unknown, 0 in Sony example
3 : PMIN of POINT A2 = Start position of Lead-Out
4 : PSEC of POINT A2 = Start position of Lead-Out
5 : PFRAME of POINT A2 = Start position of Lead-Out
6 to 11 : unknown, 0 in Sony example
@end smallexample
The following packs record @kbd{PMIN}, @kbd{PSEC}, @kbd{PFRAME} of the
POINTs between the lowest track number (1 or @code{01h}) and the highest
track number (99 or @code{63h}). The payload of the last pack is padded
by zeros.
Using the @kbd{.TOC} example from Sony documents as an example:
@smallexample
A0 01
A1 14
A2 63:02:18
01 00:02:00
02 04:11:25
03 08:02:50
04 11:47:62
...
13 53:24:25
14 57:03:25
@end smallexample
Encoding the above gives:
@smallexample
88 00 23 00 01 0e 00 3f 02 12 00 00 00 00 00 00 12 00

@end smallexample
It is unclear what Pack type @kbd{0x89} is used for, and 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
06 23:14:25 06 23:29:60
07 28:30:39 07 28:42:30
13 55:13:26 13 55:31:50
@end smallexample
Encoding the above gives:
@smallexample
89 01 28 00 01 04 00 00 00 00 02 29 30 02 34 3a f3 0c
89 06 29 00 02 04 00 00 00 00 17 0e 19 17 1d 3c 73 92

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?
@node Block Pack Type
@chapter Block Pack Type
Pack type @kbd{0x8f} summarizes the whole list of text packs of a
block. So there is one group of three @kbd{0x8f} packs per block.
Nevertheless each @kbd{0x8f} group indicates 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.
For the format of this pack type see @ref{table:block-pack}.
@float Table,table:block-pack
@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

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

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 specified ISO-8850-1
automatically as soon as content is defined which depends on the text
encoding of the block, that is, with pack types @kbd{0x80} to @kbd{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.

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}.
