B.2.2.3 bitrate

The bitrate property, expressed in bits/sec., specifies the bit rate at which the MPEG data file was encoded. This number also specifies the rate at which the file is to be played by the server to the network.

B.2.2.4 indexfile

The indexfile property is a string that specifies the pathname to the index file. The index file is an ASCII file that specifies how the bit stream being described is related to the bit stream at normal play speed. The index file is used to switch among bit streams in a content package. It is described in detail in Section B.5 “Index File Requirements” on page B-10.

B.2.2.5 indexsize

The indexsize property is an integer that specifies the number of entries in the index file identified by the indexfile property. An index file entry consists of a time/file- offset pair. See Section B.5 “Index File Requirements” on page B-10 for a description of index file entries.

B.2.2.6 datafile

The datafile property specifies the attributes of the MPEG data for a given bit stream, as described by the DataFileObjects structure.

B.2.3 DataFileObjects

The DataFileObjects structure is a sequence of data files that make up the described bit stream’s MPEG data.

B.2.3.1 segment

The segment property is an integer that specifies the sequence number of the data file in a multi-segment data file. See Section B.4 “TOC File for Large Files” on page B-9 for a description of the use of this parameter.
