Hierarchical layer C: The value depends on the settings of the hierarchical
layers A and B.

Bit Rate Display Area
Displays the maximum and current bit rates of the selected transport stream. These
values are calculated by 188 bytes/packet.
Maximum: Displays the maximum bit rate calculated from the current
parameter settings.
Current: Displays the total information bit rate of the selected transport
stream.
NOTE. If the Current value is larger than the Maximum value, the background of
the Current field will turn red to indicate that you cannot perform any
remultiplexing proce ss under the current parameter settings.
If Partial Reception is set to ON, you may not perform any remultiplexing process
even if the Current value is smaller than the Maximum value.
If the time length of an elementary stream data is shorter than that of a transport
stream file, the Curr ent bit rate for the layer that has the elementary str eam data is
not displayed correctly (see the illustration below). In this case, if you r emultiplex
the file, relative time values of PCRs and PTS/DTSs in a created ISDB-T transport
stream file may become incorrect.

Layer Change Buttons
By default, all of the transport stream components are assigned to the hierarchical
layer A. Y ou can change the lay er assignment for the components using the buttons
in the Check and Change Layer field.
A/B/C buttons: Changes the hierarchical layer of the transport stream
component that have a check mark to the hierarchical layer corresponding to
the button.
¢ button: Replaces the transport stream component that have a check mark
with a null packet.
ALL button: Selects all the check boxes of the transport stream components.
Clear button: Clears all the check boxes of the transport stream components.
Perform the following steps to change the hierarchical layer assignment for a
transport stream component:
1. Click the check box(es) of the component(s) for which you want to change the
hierarchical layer. If necessary, use the ALL or Clear button. You can select
check boxes by dragging a mouse on components with the left-mouse button
pressed. (If you drag a mouse on components with the right-mouse button
pressed, you can clear check boxes).

2. Click the A, B, C, or ¢ button to change the assignment.
Y ou can also change the hierarchical layer assignment by clicking a layer name
on the hierarchy display. In this case, the layer name changes to A-B-C-¢ in
turn.
There are some restrictions on the hierarchical layer assignment for the transport
stream components:
You cannot assign the hierarchical layer that does not set the number of
segments.
If a PCR is included within a packet that has the same PID as the other
component, you cannot assign different hierarchical layers to the
components.
If there are two or more components that have the same PID, when you
change a hierarchy layer of a component, the other components are also
changed to the same hierarchical layer.

Regenerated PCR. Selects whether to recalculate PCR values when remultiplexing
a transport stream.
NOTE. Be sure to clear the command if you have set the parameters in both Current
and Next tabs. In addition, if you play a remultiplexed transport stream created
using the Current and Next tabs from the MTX100/A or the RTX100/A, set the
Update command in the Play menu of the instrument to Off.
Duplicate Packet. Specifies whether to duplicate P AT , NIT , and CAT in null packets
in the hierarchical layer A when the following conditions are met:
1. Partial reception is specified in hierarchical layer A
.
2. Either the hierarchical layer B or C is the most robust layer.
3. PAT, NIT, or CAT is included in hierarchical layer B or C.

Operating Basics
Open Setting for no PAT TS. Enables loading a transport stream that does not
contain any P A T s (Program Association T ables) by specifying PID values for PMT s
(Program Map Tables).
When you select Utility > Open Setting for no PAT TS, a dialog box appears as
shown in Figure 2-10.
Figure 2-10: Open Setting for no PAT TS dialog box
Automatically apply this data when no PAT was found in the stream:
Sets whether to load the transport stream by using the PMT PID values that are
specified in the dialog box when loading a transport stream that does not
contain any P ATs (if a transport stream contains any PAT, it is loaded using the
P AT). If you clear the check box, a transport stream that does not contain a P AT
cannot be loaded. By default, the check box is selected.
PMT PID: Specifies each PID value for PMTs in a transport stream to be
loaded. By default, the upper eight PID values are set to those that are allocated
by the ARIB TR-B14 standard. If you do not specify a PID value for a PMT, it
is not recognized as a PMT.
If you click the Advanced button, text boxes to set more PID values and program
numbers of PMT s are displayed. Use these text boxes to load PMTs with the same
PID value but a different program number . In addition, a text box to set a PID value
for an NIT (Network Information Table) is displayed. By default, it is set to
0x0010.

Open button.
After the file is loaded, the “Analysis Complete” message appears.
3. Click the OK button in the dialog box.
4. Set the transmission parameter for remultiplexing the transport stream in the
parameters setting area.
a. Set the transmission mode in the Mode list box.
b. Set the guard interval ration in the Guard Interval list box.
c. Set the number of segments for hierarchical layers A and B in the Segment
list boxes.
d. Set whether or not partial reception is available in the hierarchical layer A
in the Partial Reception list box.
e. Set the carrier modulation scheme for each hierarchical layer in the
Modulation list boxes.
f. Set the inner-code coding rate for each hierarchical layer in the Code Rate
list boxes.

g. Set the time interleaving length for each hierarchical layer in the Time
Interleaving list boxes.
If you use the Employment Parameter command in the Utility menu, you
can set the parameters to the hierarchical transmission pattern defined in
ARIB TR-B14.
5. In the hierarchy display area, change the hierarchical layer assignment (A, B,
C, or, ¢) for transport stream components (refer to Layer Change Buttons on
page 2-6).
6. If necessary, click the Next tab and repeat steps 1 through 5 to set the
parameters.
