1kHz(L)+400Hz(R) A tone signal (left: 1 kHz and right: 400 Hz) is used (factory
default).
About the 1seg monoscope patterns
• The 1seg monoscope is derived by reducing the 720×480 (16:9) image. Scales and
charts are not adjusted to the 320×180 screen size, so this monoscope pattern cannot
be used to perform operations such as checking the original resolution. Only use the
1seg monoscope to check patterns.
When Fixed Pattern is selected, regardless of the settings that are described in section
3.2.2, “MANUAL,” the modulation p
arameters are fixed to the following settings.

● Explanation of function keys
• F4 PID Select
Press to select the PIDs to assign to each of the PN's layers
See section 3.1.6, “PID SELECT.”
• F5 Format
Select the format of the TS that you will apply.
MPEG-TS Use this setting for normal TS signals (factory default).
Depending on the carrier modulation settings, the upper limit of the TS
rate that can be applied varies. Use a TS that conforms to the settings
that you have made. For an MPEG TS, both a TS conversion that occurs
because of the encoding and a data rate conversion are carried out, so
there is no problem even if you apply an asynchronous signal to the LG
3810.
Also, the “Null Packet Filter” and “PCR Update” features are enabled. See
section 3.1.1, “TS SETTING.”
ISDB-T
Use this setting when you want to apply a broadcast TS that is defined in
ARIB STD-B31.
For a broadcast TS, note that there are the following conditions.
• Because there is no broadcast TS specification in ARIB STD-B29, only
the current television settings are used.
• Apply the signal to the SPI connector. The LG 3810 cannot handle
broadcast transport streams that are applied to the ASI connector.
• The modulation settings depend on the IIP packets within the TS.
• Apply a 32.507937 Mbps TS signal that is synchronized to the LG 3810.
If you apply an asynchronous signal, a correct signal will not be
generated.
• PID settings are ignored.

To assign the layers, follow the procedure below.
1. On the SOURCE screen, set Source to External and Format to MPEG-TS.
2. On the CODING screen, configure the modulation settings.
See section 3.2, “CODING.”
3. On the SOURCE screen, press F4 PID Select, and then specify PID number 1.
4. Enter the PID value as described in section 3.1.6, “PID SELECT.”
Enter the top PID value that is shown in Figure 3-8, 0x03F0.
Press F3 Layer to select A for the layer that this PID is assigned to.
5.
This completes the settings for PID number 1.
6. Specify PID number 2, and assign 0x0130 to layer A.
7. Repeat these steps to assign the remaining 11 PIDs that are shown in the figure to
layer A and C.
8. Press F5 Undefined PID Layer to select B.
All packets that you have not assigned by following this procedure up to step 7 will be
assigned to layer B.
9. To enable the settings that you have made, press UP MENU to return to the previous
screen or press and hold UP MENU to return to the top screen.
Notes regarding layer settings
• Use a TS whose PID tree structure is already known when you configure the LG 3810
with the above settings. The LG 3810 does not have TS tree analysis or display
features.
• The information rate that can be applied to each layer depends on the modulation
settings (guard interval, modulation method, code rate, and number of segments). If a
packet load that exceeds these settings is received, the internal buffer overflows, and
this causes the LG 3810 to generate an incorrect signal.
• You can assign up to 32 PIDs to a layer.
• Descriptor insertion and PSI editing are not supported.

3.1.8 Multiplexing PCR Packets
The LG 3810 supports the features discussed in the section titled “Multiplexing PCR
packets at the partial-reception hierarchical layer” in ARIB STD-B29 and B31. Use the LG
3810 under the following conditions.
Supported layers Partial-reception hierarchy (when used for television
PCR multiplexing position From the start of the first OFDM frame to the first
Number of multiplexed PCR packets One packet per OFDM frame (Mode 1)
Important notes regarding PCR multiplexing
• PCR multiplexing is only supported at the partial-reception hierarchical layer.
• If partial reception is enabled in the modulation settings, and PCR Update is turned ON,
the LG 3810 performs PCR packet multiplexing at the partial-reception hierarchical
layer.
• Do not use this feature with PCR packets whose adaptation field control is not “10”
(adaptation field only). If you do, payload data will be lost.
• Partial-reception hierarchical layer PCR packets that are multiplexed into a TS are
discarded.
• Only assign a single PCR packet to the partial-reception hierarchical layer. Assignment
of multiple PCRs is not supported.
• You cannot change the PCR packet multiplexing position.
• If the insertion interval exceeds the multiplexing interval (58 ms or higher in Mode 3,
GI1/8), this feature increases the number of layer A PCR packets, so be careful of the
layer overflowing.

About other segments during sequential transmission
• During sequential transmission, the LG 3810 uses dummy data to modulate and
generate the segments other than those specified above—the other seven segments
for ISDB-Tsb (8-1seg) and the other five segments for ISDB-Tsb (8-3seg). This means
that these segments may not be properly received. Even if these segments are
received, because they are random TS data, they cannot be used for tests such as BER
measurements.
