FIGURE B-1Structure 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.
