The following line is specified between <MpegStream line> and <EndMpegStream
line>:
• BitRate
Specifies the data bit rate in bps units.
The following commands can be used as the MPEG file definition:
• BeginTimeF
The start position in an ISO9660 file is specified by the relative position from the beginning of the
file. When the “+” symbol and not the relative position is specified in the parameter, the start
position continues at the end of the previously defined file source.
• EndTimeF
The end position in an ISO9660 file is specified by the relative position from the beginning of the
file. When the “-” symbol and not the relative position is specified in the parameter, the start
position continues at the beginning of the previously defined file source.
• AutoEOR
Shows the recording of EOR (EndofRecord) to the sector subheader that stores the final file source
bytes. This command is valid only in MODE2-type tracks.
• RealTime
Shows that this file source is a real-time file.
Defining File Sources
A file source is an MS-DOS file that stores the data that is the source for configuring
ISO9660 files. The file source is defined between
<FileSource line> and
<EndFileSource line>. The FileSource line parameter becomes the data file name.
The following line specifies the data file’s characteristics. All of the following com-
mands can be omitted.
• SourceType
Specify one of the following types to the parameter:
— MONO_A
Data is ADPCM at mono_level A.
— MONO_B
Data is ADPCM at mono_level B.
— MONO_C
Data is ADPCM at mono_level C.
— STEREO_A
Data is ADPCM at stereo_level A.
— STEREO_B
Data is ADPCM at stereo_level B.
