Appendix B Creating a Content Package B-3
FIGURE B-1 Structure of a Content Package
Note – If your content consists of a single bit stream, you do not need an index file.
You content package will consist of only a Table of Contents file and the single bit
stream.
B.2 The TOC File
The Table of Contents (TOC) file is an ASCII file that contains:
■ a list of all of the bit streams in the content package;
■ the individual data and index files that make up these bit streams;
■ relevant attributes of these bit streams.
The structure of the TOC file is specified using the Abstract Syntax Notation One
(ASN.1). ASN.1 is a standardized way for describing structured information. See
Section B.8 “References” on page B-18 for the standards that specify ASN.1.
