B.1 Content Package
A content package is a collection of separate MPEG streams that represent the content
of a title (including audio and video) at various playback speeds.
There are two types of files that together describe each of the (potentially) multiple
bit streams that make up a content package:
■ the data file containing the MPEG-encoded data;
■ the index file that contains information on how a specific data file is related to the
rest of the content.
In addition to a data file/index file pair for each bit stream, a content package
contains a single Table of Contents (TOC) file. The TOC file contains information on
each of the bit streams in the content package. The TOC file is covered in detail in
the following section.
A content package must contain at least one bit stream, the bit stream representing
the movie at normal playback speed. See Section 2.2 “MPEG Encoding
Requirements for Trick Play” on page 2-2 for a discussion of the use of additional bit
streams to support VCR-like functions, such as fast-forward and rewind.
FIGURE B-1 illustrates the concepts inherent in a content package.
