3.8 Defining file source information

3.8.1 Definition of subheader information

Format: SubHeader
parameters: none
function: Declare that data with subheaders will be used as a file source.
remarks: The validity of subheader information is not checked. Also, the builder does not set any information in the subheader. Therefore, please specify directory information such as file number so that it is consistent with subheader information.

Format: DataType form
parameters: form: Form name (FORM1 or FORM2)
function: Specifies the form format of file source data.
remarks: Valid only within the MODE2 track.

parameters

srctype: File source type

function

Specifies the type of file source data.

(1) File source type

type name	explanation
DATA	data
AUDIO	Audio (audio data other than ADPCM)
VIDEO	video
MONO_A	ADPCM monaural level A
MONO_B	ADPCM monaural level B
MONO_C	ADPCM monaural level C
STEREO_A	ADPCM stereo level A
STEREO_B	ADPCM stereo level B
STEREO_C	ADPCM stereo level C
CDDA	CDDA data
ISO11172	ISO11172 stream (MPEG system layer)
MPEG_VIDEO	MPEG video stream

remarks

Valid only within the MODE2 track.

Format: AutoEOR
parameters: none
function: Sets the EOR bit of the subheader of the sector that stores the last byte of the file source.
remarks
Valid only within the MODE2 track. In the case of MPEG source definition, it is automatically added, so there is no need to write it.

Format: RealTime
parameters: none
function: Indicates that the file source is a real-time file, and sets the RealTime bit in the subheader of the sector to be recorded.
remarks
Valid only within the MODE2 track. If the data type specified in the MpegStream line is AUDIO or VIDEO, it will automatically become a real-time file, so there is no need to write it.

Format: CodingInformation codeinf
parameters: codeinf: Coding information value
function: Sets the specified value in the coding information field of the subheader that records the file source.
remarks: When using MpegMultiplex, if you specify the data type as VIDEO with the MpegStream command, it will be set to 0FH, and if you specify it as AUDIO, it will be set to 7FH.

3.8.2 Defining file placement control information

Format: BeginTimeF relpos
parameters: relpos: Starting position to place the file source (relative time from the beginning of the file)
function: Places the file source starting at the specified position.

Format: EndTimeF relpos
parameters: relpos: End position to place the file (relative time from the beginning of the file)
function: Places the file ending at the specified position relpos.

Format: Offset of length
parameters: ofs: File source reading start position (in bytes); length: Size to read the file source (in bytes)
function: Reads data of size length from position ofs in the file source.

Format: UnitSize usize
parameters: usize: Number of sectors in a unit (a sequence of sectors in which the same channel is placed consecutively)
function: During channel interleaving, sectors of the same channel are recorded in units of the specified unit size.
remarks: If the UnitSize command is omitted, the unit size is 1.

Format: GapSize gsize
parameters: gsize: Number of sectors in the gap (sector sequence between units)
function: When channel interleaving, units are recorded at intervals of the specified gap size.
remarks: If the GapSize command is omitted, the gap size is 0.

Format: BitRate bps [seqno]
parameters: bps: Bit rate (in bits/second); seqno: MPEG stream sequence number (default = 0)
function: Records channel data at the specified bitrate.
remarks
Bitrate is a number with a decimal point. For integer values, add .0. seqno is kept for compatibility. No need to write.
