bytes and one or more text packs of 18 bytes each. Suitable would be the
|
||||
file 'cdtext.dat' which gets extracted from CD media by options -vv -toc
|
||||
and shown in human readable form by -vvv -toc.
|

.br

The header, if present, must tell the file size minus 2, encoded as big-endian

A text pack consists of a pack type byte, a track number byte, a counter byte,
|
||||
a Block Number and Character Indicator byte, 12 text characters or data bytes,
|
||||
two optional CRC bytes.
|
||||
.br
|

Pack types are: 0x80=Title, 0x81=Performers, 0x82=Songwriters,
|

0x83=Composers, 0x84=Arranger, 0x85=Messages, 0x86=Disc Identification,

0x87=Genre Identification, 0x88=Table of Content Information,
|

0x89=Second Table of Content Information, 0x8e=UPC/EAN resp. ISRC,
|

0x8f=Size Information of the Block.
|

.br
|
||||
Track number 0 means the whole disc. Higher numbers are valid for types 0x80
|
||||
to 0x85, and 0x8e. With these types, there has to be one text for the disc
|
||||
and one for each track.
|
||||
.br
|
||||
Block Number and Character Position Indicator consists of three bit fields:
|
||||
Bit 7 indicates two-byte characters. Bit 4 to bit 6 record the block number,
|
||||
which groups texts into language blocks.
|
||||
Bit 0 to bit 3 is 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.
|
||||
.br
|
||||
The texts are terminated by 0 bytes. 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.
