Replacing and Inserting Section Data (MTG300 Only)
The MTG300 MPEG Generator provides the capability to replace section data
such as CATs, NITs, PATs, and PMTs in a transport stream with user-specified
data. The MPEG generator also allows you to insert user-specified section data
into a transport stream.
These features allow you to change the status of SI or PSI tables to check if a
receiver is operating correctly when the table information is updated.
NOTE. The MPEG generator uses files stored in the /main/usr/insert directory on
the hard disk to replace or insert user-specified section data. Therefore, before
you can replace or insert section data, an appropriate section file must be stored
on the hard disk.
For example, if you want to replace the PMT in a transport stream, you must
first store a *.pmt file in the /main/usr/insert directory on the hard disk.
This subsection provides instructions on how to replace or insert section data
into the transport stream.
Replacing Section Data
Perform the following procedure to replace section data in the transport stream:
1. Use the Icon cursor to select the transport stream item in the hierarchy
display that you want to replace. If the Icon cursor is not displayed, press the
MENU button to enable the Icon cursor.
2. Press the Replace Section... bezel button. This opens the Select Replace
File dialog box shown in Figure 3-23.
3. In the Select Replace File dialog box, select the section file that you want to
use as the replacement file.
4. After you select the desired replacement file, press the OK bezel button.
This closes the Select Replace File dialog box and opens the Replace Setup
dialog box shown in Figure 3-24.
