Example
This section provides an example of a content package—the TOC file and the index
and data files for each bit stream—and its storage on a tape using the
tar
format.
The names of the files that make up our example content package are shown in the
tar
output, below:
The
tar tf
command above lists the table of contents on a
tar
file or device,
/dev/rmt/0
in this example. The
tar
output indicates that the content package
consists of a TOC file,
bambi.TOC
, and five bit streams associated with the content
at various speeds. Each bit stream contains an index file (
.index
) and an MPEG
data file (
.mpeg
).
In our example, as in
FIGURE B-2
on page B-13, the index files for a content package
appear immediately after the TOC file on the tape.
